Spineless!

~ millennialmatriarchs ~ Leave a comment

Fountain of Bees, Rome

They make up over 90 per cent of life on earth.

There are about 1.3 million species of them.

They are found in every part of the world.

They range from one-fifth the thickness of a strand of your hair, to the 30 ft long giant squid.

These are the invertebrates—animals without a backbone. Why backbones, in fact, invertebrates don’t any bones at all! Invertebrates include ants, spiders, worms, snails, bees, butterflies, corals, lobsters, crabs…they are the spineless majority!

As the famous biologist EO Wilson put it, ‘Invertebrates don’t need us, we need invertebrates’.  Critically, they pollinate flowers, hence allowing plants to propagate so that there is food for all. They are at the base of all food-chains.  Humans also eat invertebrates—think crabs, lobsters etc. They maintain the ecological balance by eating each other and being eaten! Earthworms and some related creatures help dig up and aerate the soil, and make it fertile. They are important in another way too—most parasites are invertebrates!

All invertebrates are cold-blooded and about 80 per cent of them are terrestrial. Most of them undergo metamorphosis.

They fall into nine phyla, compared to vertebrates which all belong to one phylum.

In spite of their ubiquitous presence and the role they play in our lives, we don’t pay enough attention to these co-inhabitants of our world. For instance, while most countries have national animals or birds, few have national invertebrates. Exceptions include Denmark, which lists the Small Tortoiseshell as its national butterfly; Estonia which lists the Swallowtail; Finland which lists the Seven-spot Ladybird as its national insect and Latvia which has the Two-spot Ladybird for its. Several US states have State Insects, as does Karnataka (the honeybee). Many Indian states also have State Butterflies.

India is unique in that it has named a National Microbe—the Lactobacillus bulgaricus. This was done in 2012, based on a nation-wide completion. It was selected based on its importance in making yogurt or curd. Some US states also have State Microbes. The first state to declare an Official State Microbe was Oregon which chose brewer’s or baker’s yeast as the Official Microbe because of its importance to the craft beer industry there.

Designating such national and state symbols is important, given that we don’t focus enough on these creatures which make up about 95 per cent of all species on earth. Creating a buzz brings attention to them, hopefully leading to more studies and research, ensuring their well-being which is so critical to ours.

In order to increase awareness about invertebrates, last year the well-known British newspaper The Guardian started an ‘Invertebrate of the Year’ contest. This was confined to the UK. This year’s competition, the second of the series, has gone international. So any of us can send in a nomination for an invertebrate, along with reasons why we favour this particular one.

To give you an idea, last year’s winner was the earthworm, which was voted in with 38 per cent of the total votes. The least number of votes was garnered by the invasive Asian or yellow-legged hornet.

Surely you have an invertebrate you love or hate. This is your chance to put it on the world map. Submit your entries at https://www.theguardian.com/environment/2025/feb/12/nominate-your-invertebrate-species-of-the-year by midnight (GMT) on Tuesday 4 March.

Pulses Rule!

~ millennialmatriarchs ~ 1 Comment

They are at the heart of every meal; they come in many colours, shapes and sizes; they can be used in a large range of permutations and combinations. They are the pulses that are an integral part of all cuisines in India. In a country with such immense diversity in culinary traditions, food habits, and meals, pulses are the one common as well as essential element. Our daily meal is incomplete with a dish made from a pulse, and many of our favourite snacks would not be what they are without pulses. Yet there is much that we have never stopped to really think about.

Technically pulses are the edible seeds obtained from the cultivation of leguminous plants for both food and feed. India has an immense diversity of pulses at the genetic and species level, as well as their uses at the culinary level. What makes pulses the original ‘wonder food’?

These seeds are a rich source of nutrients, mainly proteins, that are crucial for a healthy and balanced diet. It is estimated that 100 grams of dry lentils contain about 25 grams of protein. Thus pulses can become a backbone of a vegan diet.

They are naturally low in fat and contain no cholesterol, reducing the risk of cardiovascular diseases. They are also low in sodium chloride or salt which is a contributor to hypertension. They are high in potassium which plays an important role for digestive and muscular functions.

Pulses are a good source of iron and a great answer to address iron deficiency. The iron in pulses is best absorbed in the body by combining them with foods containing vitamin C. They are an excellent source of folate, a B-vitamin essential for nervous system function. They have a low glycaemic index, which makes them suitable for people with diabetes. They are naturally gluten-free, making them an ideal option for those who are gluten intolerant.

They can be stored for a long time and can be used even when fresh seasonal fruits and vegetables are not available. Their long shelf-life prevents food loss and wastage.

Pulses are incredibly versatile and can be used in an endless variety of cuisines and dishes in numerous forms. 

That is so far as human health goes, and most people are, at some level, aware of these attributes of pulses (a lot of which is passed down through generations by family recipes and ‘granny’s words of wisdom’). But there is not as much awareness about the fact that pulses are as important for environmental health as they are for human health.

Pulses play a vital role in soil health by providing essential nutrients, maintaining soil biodiversity, and enhancing soil structure. They improve soil health by hosting helpful bacteria, called rhizobia, in their roots. These bacteria convert nitrogen from the air into fertilizers in the soil. Additionally, other bacteria and fungi help release phosphorus in the soil, providing essential nutrients for plants and promoting soil diversity. The fertilizers produced by pulses benefit not only the pulses, but also other crops grown alongside them, reducing the need for chemical fertilizers. This makes pulses ideal for sustainable farming practices like intercropping or crop rotation. Additionally, pulses and their by-products are utilized as animal feed.

The benefits are not limited to soil alone. Pulses also perform other ecosystem services. Many pulse species are drought tolerant and resilient to adverse climate, such as drought and heat. Their cultivation optimizes fertilizer use, thus reducing greenhouse gas emissions.

Pulse crops have a lower carbon footprint than most foods because they require a small amount of fertilizer to grow. They also have a low water footprint as they are adapted to semi-arid conditions and can tolerate drought stress.

Despite their immense value for human and environmental health, pulses are not generally ‘stars’; they are often undervalued and under-recognized. In an effort to highlight the importance, as well as potential, of pulses as a global food the United Nations declared 2016 to be the International Year of Pulses. As the then UN Secretary General Mr Ban-ki-Moon said: “The International Year can help overcome this lack of knowledge. Much work needs to be done to end hunger and provide food security and nutrition for all. One concrete, promising opportunity lies with pulses. Let us join forces to raise awareness of the benefits of pulses”.

As the world was embarking on efforts to achieve the newly-adopted Sustainable Development Goals it was hoped that this International Year would help raise awareness of the benefits of pulses globally. The year-long celebration was implemented by the Food and Agriculture Organization (FAO), a specialized agency of the United Nations. The year was a success, and recognizing the potential of pulses in further achieving the Sustainable Development Goals, since 2019 the United Nations General Assembly has designated 10 February as World Pulses Day to be celebrated every year.  

This celebration is a recognition of the decisive role that pulses can play in achieving the comprehensive, far-reaching and people-centred set of universal and transformative goals and targets of the United Nations’ 2030 Agenda for Sustainable Development.

The World Pulses Day celebrations are an opportunity to raise public awareness about pulses and the fundamental role they play in the transformation to more efficient, inclusive, resilient and sustainable agrifood systems for better production, better nutrition, a better environment, and a better life, leaving no one behind.

This is a good day to look more closely at our own meal! What is the original colour of the pulse on your plate? Green, yellow, red, brown, orange, black, white…

In what form are you eating your pulses? As a Dal (sweet Gujarati or Punjabi tadka?) Rajma-chaval or chana puri? As a part of your idli-sambar? As the partner to rice in khichadi? As the coating on your pakodas? As the sweet moong dal halva or payasam? Each platter will have a different version of pulses!

Whatever the form and whatever the taste, pulses rule our plates and palates!

Avian Ambassadors: National Birds

~ millennialmatriarchs ~ Leave a comment

A news item that President Joe Biden had signed a bill on Christmas Eve 2024 that designated the bald eagle as the national bird of the USA was confusing, to say the least. One had always assumed that this had always been so, given that it was seen on all official US documents, and indeed even the US passport. It turns out that while the bald eagle has been the national symbol since it appeared on a copper cent in 1776, and has been appearing on the Great Seal of the US since 1782, the bird had never been legally recognized as the national bird till 24 December 2024.

Behind this lies an old story. On 4 July 1776, the Declaration of Independence was signed whereby the 13 American colonies severed their political connections to Great Britain. Following this it was decided that the new nation should have an official seal. It took three committees and six years before the seal was finalized on20 June 1782. The seal denoted a bald eagle grasping an olive branch and arrows in its talons. The significance of this is explained thus: ”The olive branch and the arrows held in the eagle’s talons denote the power of peace and war. The eagle always casts its gaze toward the olive branch signifying that our nation desires to pursue peace, but stands ready to defend itself”.

The bald eagle lives only in North America and to the people of the newly-born republic this bird was a symbol of courage, strength and freedom. It soon became a cultural and political symbol appearing on official documents, US currency, military insignia, and popular merchandise. Thus the bird remained a national emblem in the US for nearly 250 years, but it had not been officially designated to be the national bird until Congress passed the bill.

Many countries have a national bird. These are usually representative, in one way or another, of the country that they are the designated symbol of. The designation is done in different ways. The approaches range from the official, semi-official or unofficial, ranging from government decrees to popular vote. The choice is usually from among birds that have a high recognition factor.

Some countries in Central and South America have selected flamboyant birds as their national symbols, while some have selected bird species that are unique to their country. Among these are Gautemala’s Resplendent Quetzal and Papua New Guinea’s Raggiana Bird-of-paradise, which are spectacularly colourful. A beautifully matched choice is that of the Cuban Trogon or Tocororo whose colours exactly match the colours of Cuba’s flag. These birds cannot survive in captivity, and thus symbolizes the people’s love of freedom.

Some countries have selected threatened species in the hope to promote their conservation measures, like Bermuda’s Cahow or Bermuda Petrel (endangered) and Cambodia’s Giant Ibis (critically endangered). While Dodo is the unofficial mascot of Mauritius, seen as a symbol everywhere, it is sadly extinct. Thus the country has officially adopted the Mauritius Kestrel as its national bird. This is a rare bird of prey, endemic to the island and its recovery from near extinction (only four known individuals in the wild in 1974) to over 350 kestrels today, is a successful conservation story.  

Some Arab states have also designated other species of falcons as national birds. These birds represent grace, elegance, ability and alertness, and are considered a symbol of bravery. A variety of eagles have been a favoured choice of several countries for these very attributes. These include golden eagle (national bird of Albania, Mexico, Kazakhstan, Scotland, Serbia, and Germany), African fish eagle (Namibia, Zambia, Zimbabwe), harpy eagle (Panama), Javan hawk-eagle (Indonesia), Philippine eagle (Philippines), and the white-tailed eagle (Poland).

The raptor with the largest wing span in the world, the Andean condor of South America has been designated the national bird by several countries in that continent for its different qualities–Bolivia (for boundary-less pursuit), Chile (for strength), Colombia (for liberty and order), and Ecuador (for power, grandeur, and valour).

Whereas Japan could have adopted the Red-crowned crane as its national bird because of its scientific name Grus japonensis, it has chosen the kiji or Green pheasant. This bird is said to be particularly sensitive to earthquakes, to which Japan is prone. It is also features in many literary works.

Curiously, Grus japonensis was selected to be the national bird of China through an internet survey which was launched by the Chinese Wildlife Animals Protection Association and about 20 news organizations in 2004. The Red-crowned crane was the choice of about 1.3 million Chinese netizens to be the national bird.

Britain was pretty late in the naming of its national bird. In 2015 there was an online poll of over 200,000 people in Britain to vote for a national bird in response to a campaign started by ornithologist David Lindo. From an original list of 60 birds, online voters arrived at a shortlist of 10 birds. The Robin won first place with 34% of the vote, followed by the barn owl and blackbird.  

Another popular vote led to the change in Denmark’s national bird. Till 1984, the Skylark was the national bird, but a poll held by a TV show indicated that the more popular choice was the mute swan. The mute swan’s Danish name (Knopsvanen, literally meaning ‘the knob swan’) refers to the black knob it has over its orange beak. This selection was not based on natural history criteria but rather the association of the bird with Hans Christian Anderson’s famous fairy tale about the ugly duckling that grew into a swan.

Thus there are many reasons and many avenues that make a national bird. Closer to home, there is an interesting tale. In the 1960s the Government of India was encouraged by international bird conservation organisations to select a national bird. It was suggested that this could be a bird species that was in immediate need of protection, and thus attention. The most obvious choice at the time was the Great Indian Bustard that was already endangered then, with less than 1300 individuals in the wild. The famous ornithologist Salim Ali emphasised that this spectacular bird required “an urgent, nation-wide effort” to save it from its impending doom. As the story goes, in this respect, the Bustard was a logical choice. But there was a concern that its name could easily be misspelt or mispronounced, leading to much embarrassment! Whether this is just jest or a fact, it was the peacock which made the title in 1963, not because of its conservation status, but because of its cultural significance, religious and legendary associations, beauty, and widespread distribution in the country.

Contested Hedges

~ millennialmatriarchs ~ Leave a comment

Contested borders are in the news every day. You can’t miss the claims and counter-claims between neighbouring countires—in our case, mainly China.

But it seems that disputes between neighbours on humble garden hedges are as serious. In the UK, disputes between neighbours on this issue have even resulted in deaths, with one Mr. Wilson of Lincolnshire, dying from gunshot wounds sustained during an argument over hedges, and a Mr. Reid dying of a heart attack after a heated dispute with his neighbour on the same subject. While not so drastic, many people have been levied stiff fines on the charge of trespass for cutting their neighbours’ encroaching hedges. In all, there were 1,00,000 hedge disputes in the UK prior in 2003.

Why do these disputes arise? A major reason is that the hedge blocks too much light to a neighbour’s house or garden; or that the hedge blocks a view. Or a neighbor’s overgrown hedge may encroach on your property. Also, branches or roots may cross into your property from a neighbor’s property or a public road.

This serious situation led to the passing of laws to manage the situation. In 2003, UK passed laws to manage disputes related to hedges. The UK Law essentially is about ‘high hedges’ defined as those over 2 meters in height. Transgressions of hedge-related law come under the definition of Anti-Social Behavior, since 2003!

The situation is understandable, given the extent of hedges in the UK. Laser scanning has shown that the UK has 390,000 km of hedges and hedgerows (1-6 metres tall) on field boundaries– enough to go round the world almost 10 times.

A step back. What is a hedge? A hedge is a line of shrubs (and occasionally trees), planted closely (3 feet or closer) which form a barrier or mark the boundary of an area, such as between neighbouring properties. Hedgerows on the other hand are hedges used to separate a road from adjoining fields, or one field from another, and which may incorporate larger trees. Apart from demarcating boundaries, hedges and hedgerows may serve as windbreaks to improve conditions for crops, as. A hedge is also called a “live fence”.

Under the UK Law, these disputes don’t go to court. Neighbours are encouraged to reach negotiated settlements. If this does not work, a written complaint may be given to the local Council, which will look into both sides of the argument and give a decision. Either the Council will reject the complaint, or they will give an order to cut the hedge to the mandated height. The cutting has to be done keeping in mind The Wildlife and Countryside Act 1981 which makes it an offence to destroy any bird’s nest that is either in use or being built!

Few other countries have such elaborate laws on the subject. However, some local authorities in the US do regulate the height or placement of hedges. For example, a resident of Palo Alto was arrested for allowing her xylosma hedge to grow too tall.

So go ahead. Do grow your Photinia, Duranta, Golden Cypress, Nerium, Hibiscus, Copper Leaf, Ixora, Tecoma, Vilayati Mehendi or whatever else takes your fancy. But make sure they don’t inconvenience your neighbours and get your behaviour labelled as anti-social—at least under the UK laws!

If everyone could plant hedges and learn to maintain them with discipline, maybe we will also learn to manage other boundary disputes without resorting to violence.  It could make for a world where boundary disputes become a thing of the past!

The Ultimate Flower-Clock

~ millennialmatriarchs ~ Leave a comment

Wouldn’t it be beyond-beautiful if we had a clock which did not tell time by mundane numbers and needles, but by a particular flower blooming? Imagine if you peeped out of the window and you could look at this clock, and tell if it was 12 noon, or 1 pm or 2 pm by the flower that was blooming!

This was the kind of clock that Carl Linnaeus dreamed of.  Linnaeus’s flower clock or Horologica Floræ is a garden-plan thought up by Linnaeus that would take advantage of plants that open or close their flowers at particular times of the day, to accurately indicate the time.

As most of us would remember from school-biology, Linnaeus was the Swedish naturalist who laid down the principles for defining genera and species of organisms, and created a uniform system for naming them (the binomial nomenclature). His book, Systema Naturae (The System of Nature) consisted of only 11 pages but laid the foundations of taxonomy. It presented a hierarchical classification or taxonomy, of the three kingdoms of nature: stones, plants, and animals. Each kingdom was subdivided into classes, orders, genera, species, and varieties. All modern classification systems in biology have their roots in the Linnaean classification system which is based on similarities—for instance, Linnaeus grouped together organisms that shared obvious physical traits, such as number of legs or shape of leaves.

The Linnaean system of classification consists of a hierarchy of groupings, called taxa (singular, taxon). Taxa range from the kingdom to the species. The kingdom is the largest and most inclusive grouping. It consists of organisms that share just a few basic similarities. Examples are the plant and animal kingdoms. Then come the phylum, then the class, order, family, genus, and finally the species–the smallest and most exclusive grouping. It consists of organisms that are similar enough to produce fertile offspring together.

Linnaeus greatest contribution to science was his method of naming species. This method, called binomial nomenclature, gives each species a unique, two-word Latin name consisting of the genus name and the species name. An example is Homo sapiens, the two-word Latin name for humans, literally meaning “wise human.”

But if Linnaeus saw order in the natural world around him, he saw beauty too. In around 1748 he started thinking about the flower-clock. It builds on the fact that there are species of plants that open or close their flowers at set times of day. In his publication Philosophia Botanica, he gives 46 examples of flowering plants that are open during particular parts of the day. He brought together 43 of these under the heading Horologium Florae, or Floral Clock, arranging them in a time sequence from 3 am to 8 pm. The time at which each flower opens and closes is given in whole and half hours.

To give you a glimpse, here are a few rows from Linnaeus’ table:

Botanical nameCommon nameOpening timeClosing time
    
Tragopogon pratensisGoat’s-Beard3 a.m.–
Cichorium intybus L.Chicory4–5 a.m.–
Reichardia tingitana (L.) RothFalse Sow thistleby 6 a.m.10 a.m.
Taraxacum officinale WeberDandelion5 a.m.8–9 a.m.
Crepis alpina L.Hawk’s beard5 a.m.11 a.m.
Hieracium umbellatum L.Hawkweed6 a.m.5 p.m.

Though Linnaeus worked for years on this, the observations and hence selection and organization of flowers were not complete.  Linnaueus’ son Carl the Younger was given the task for completing the table so that the clock could be built. Unfortunately, Linnaeus the Younger’s floral clock was never completed, and his observations on the opening and closing of flower have not been found among his surviving papers.

Alas, no one has actually built such a clock, and it is not even clear that it is possible.  There are many practical issues to overcome. For instance, it would only function for part of the year since plants don’t flower through the year; the time shown would be indicative at best since blooming times are in a range and would vary with specifics like weather and other atmospheric conditions; many of the plants that Linnaeus observed and selected were wildflowers from Sweden and may not be found in other places, or would behave differently in other places. And then, the clock may not work at all in some seasons, if there are not enough flowers which bloom then.

Well, in this digital age, there are some ingenious people who have created an app based on the idea. They have selected 24 flowers, one for each hour that would normally flower at that time of the day or night. Floræ – Linnaeus’ flower clock app is free on appstore for Apple and iPhone.

So maybe we have make do with that, till some genious actually builds the Horologica Floræ to blow our minds!

The Black-eared One: Caracal

~ millennialmatriarchs ~ Leave a comment

It is arguably the least-known cat-species of India. Its popular vernacular name based on the Persian words is syah (black)and gosh (ear). This is the caracal—the black-eared one. Caracals inhabit dry, arid regions and moist woodlands, living in small herds. They mark territory by clawing trees and releasing scent from glands on their faces and between their toes. They communicate with meows, hisses and spits.

A medium-sized cat (about the size of a jackal) with fur in varying shades from reddish-fawn to dull sandy, the caracal is distinguished by its ears. The ears are longer than in most felines and are pointed at the tips that end in an erect tuft of hair. The ears have almost 20 different muscles that control independently the motion of each ear and aid in their wide range of movements, which they use for a variety of communication. The ear tufts act as sensitive antennae, with the ability to detect even minute vibrations.

Strongly muscled with tall rear limbs the caracal is the athlete of the cat world. It can run at a top speed of 80 km an hour and can change direction in mid-air. It can launch its whole body as high as 10 feet above the ground in one jump, and can even catch birds in flight. This litheness enables it to be an effective predator; its diet includes rodents, rabbits and birds, it is known to subdue prey much larger than itself.

It is this ability that that made the caracal a favoured hunting or coursing animal in medieval India. The caracal was a favourite pet among royalty, dating back to the time of the Mughal emperors and on to the Maharajas in the British times. Caracals were tamed and trained to hunt game, especially birds. They used to be transported to hunting grounds hooded and leashed on a bullock cart, from where they were set after prey. Using its speed and agility, the cat would swiftly bring down large game birds like cranes, hares, antelopes and even foxes. However once it had successfully hunted the caracal would ferociously hang on to it, making it difficult to retrieve the kill. 

Caracals feature commonly in literature from the Mughal through to the British rule period, indicating that they were fairly common, and considered significant. In later years these cats began to disappear from the landscape and literature. As a result the caracal remains one of the least studied species of Indian felines. Their shy and elusive nature makes them difficult to spot in the wild; they are rarer to spot than a tiger.

Conservation biologist Dharmendra Khandal who has spent many years looking for studying this elusive creature has spotted the cat only five times in twenty years compared to the hundreds of times he has seen tigers. Today he is one of the few caracal experts in India. Research on this elusive nocturnal cat is incredibly difficult  because there are no captive caracals in the country.

Once found all across Central Asia and the Indo-Gangetic plains, today these cats are rarely, if ever, sighted in these parts. While the cheetah got hunted to extinction, the reasons for the vanishing of the caracal in India are not clear. While they may face a variety of threats. Increasing area under irrigated agriculture in the arid and semi –arid region that the caracal inhabits has led to habitat modification and loss. This has also affected its diet which earlier consisted largely of birds, but now includes rodents. Human intrusion due to increasing population, and increased activity such as large scale mining and setting up wind factories in the already fragile landscape has driven these cats to near extinction.

And indeed they have vanished. A 2015 study threw up the grave concern that only two populations of the cat remain in India. It estimated that only some 28 caracal individuals were believed to be in the Ranthambhore Tiger Reserve in Rajasthan, and around 20 in Kutch in Gujarat. Scientists fear that after the Asiatic cheetah, that was declared extinct in 1952, the caracal will be the second cat species to be wiped out from the country.

While the species is listed under “least concern” under the IUCN Red List globally, it has been listed as “near threatened” by the Conservation Assessment and Management Plan and IUCN Red List assessment in India. The species is included in the Schedule-I category of the Indian Wildlife (Protection) Act, 1972, offering it the highest possible protection.

Currently, three Protected Areas, namely, Ranthambore National Park and Kailadevi Wildlife Sanctuary in Rajasthan and Narayan Sarovar Wildlife Sanctuary in Kachchh, Gujarat are the only known strongholds of Caracals in India. Viable populations outside these protected areas remain either unknown or poorly monitored. 

In 2021, the National Board for Wildlife and the Ministry of Environment, Forest and Climate Change announced a Species Recovery Plan for the conservation and population revival of 22 species in India, including the caracal.

A ray of hope comes in the form of the recent news that the royal family of erstwhile princely state of Kachchh has transferred the ownership of Chadva Rakhal, part of their ancestral property to the state government of Gujarat for conservation of biodiversity.  The Government has transferred the 4,900-hectare woodlot to the Forest Department to support conservation efforts. The area will also include a caracal conservation breeding centre which will focus on the protection and breeding of the rare and critically endangered Caracal.

 A heartening gesture indeed.

Counting cows…

~ millennialmatriarchs ~ Leave a comment

We the people of India have been waiting to be counted for over four years now. The decadal census of people, which is supposed to be the basis of policy-making has been delayed since 2021, breaking a tradition after seven fairly on-time exercises.

Well, our four-legged co-inhabitants are luckier. The 21st Livestock Census started last week, and will take places over almost five months, from October 2024 to February 2025. It will cost about Rs. 200 crore, and around 1 lakh field officials–mostly veterinarians or para-veterinarians–will be involved in the enumeration process. Though 95.8% of livestock population is in rural areas, the census will cover both rural and urban areas.

Livestock is defined as ‘domesticated animals raised in an agricultural environment to produce labour and commodities such as meat, eggs, milk, fur, leather and wool’. This particular census will collect data on15 species of livestock– Cattle, Buffalo, Mithun, Yak, Sheep, Goat, Pig, Camel, Horse, Ponies, Mule, Donkey, Dog, Rabbit and Elephant, capturing data on 219 indigenous breeds of 16 species. Apart from livestock,the headcount of poultry birds — Fowl, Duck, Turkey, Geese, Quail, Gini Fowl, Ostrich and Emu — will also be taken. The age, sex and use of each individual animal will be documented.

The census will involve officials going from door-to-door to collect detailed data on domesticated animals and birds across the nation—including not just households (about 30 crore), but also household enterprises, non-households (private sector, cooperative sector, etc.) and institutions. Information about the animals will be collected, as also information on instruments and machinery used for animal husbandry. This census will leverage mobile technology for data collection and transmission and hopefully, this will enhance the accuracy and efficiency of data collection.

The Livestock Census has a hoary history in India, with the first one being conducted in 1919-1920. It is conducted every five years with the 20th Livestock Census taking place between October 1, 2018 and September 20, 2019. It put the total Livestock population at 536.76 million, showing an increase of 4.8% over Livestock Census-2012.  Total Bovine population (Cattle, Buffalo, Mithun, and Yak) was 302.79 million in 2019 which shows an increase of 1.0 per cent over the previous census.

The livestock sector is critical in our country given that it provides livelihoods to over 2.1 crore people. It contributes about 6 per cent to the total GDP, and 25 per cent to the Agricultural GDP. The share of livestock in agricultural sector GDP growth has been increasing faster than the crop sector. This is fuelled by rising incomes, a rising population and increased urbanization, which are all propelling demand for livestock products, and hence the rising importance of this sector. As per the 20th Livestock census, the total livestock population shows an increase of 4.6 per cent over the Livestock census 2012. India has the largest population of cattle of any country in the world, with about 33 per cent of the total number.

Worldwide, livestock make up almost 10 per cent of vertebrate biomass—more than human beings, wild birds and wild animals put together! While today cattle make up the largest livestock group worldwide, it was sheep which were among the first animals to be domesticated—probably as early as 10,000 bce.

While there is enormous potential for livestock to contribute to livelihoods of the poor especially women, there are many challenges in India—from disease, to lack of access to veterinary care, vaccination, insurance, fodder and clean water, to diminishing grazing lands,  to challenges in increasing productivity, to lack of organized markets which leads to the exploitation of the sellers, to tackling the contribution of this sector to climate change.

The Livestock census aims to provide data to frame policies and programmes which will hopefully improve the situation.

But as they count cows, maybe they need to count humans too. We too could do with better policies and programmes in many, many areas of life!

River as a Living Entity

~ millennialmatriarchs ~ Leave a comment

World Rivers Day is marked across the world on the fourth Saturday of September every year. In times when rivers in every country in the world face an array of threats, this day is an opportunity to highlight the integral role of rivers in the environment and lives of all living beings, and to encourage the improved stewardship of all rivers.

The proposal for a global event to celebrate rivers was led by Mark Angelo an internationally-renowned river advocate. The proposal was accepted by the United Nations which had launched the Water for Life Decade in 2005 to help create greater awareness of the need to better care for the world’s water resources. The World Rivers Day was observed for the first time in 2005. Since even as people are reminded of the critical role of rivers as indicators of a healthy ecosystem, rivers across the globe are being sapped of their vital lifeblood.

Whanganui River

The ancient civilizations and peoples not only understood this role of rivers, but also revered it. Perhaps the most telling example of this reverence is the link between the indigenous Maori community in New Zealand, and their deep connection with the Whanganui River. The Whanganui tribes have for centuries lived along the river from which they get their name, and fished in it for food and livelihood. But for them the river is equally central to their spiritual practices; it is sacred. It defines their self-identity; as their proverb indicates: I am the river. The river is me.

The large-scale advent of European settlers to New Zealand in the 1840s changed the situation. Increasing trade and riverboat traffic began to take a toll on the river ecosystem. While Maori chieftains and the British Crown signed a treaty to guarantee the Maori the continuation of their rights and privileges, the situation on the ground was very different. Over time, the different resources of the river–water, aquatic life, riverbed gravel, the waterways that supported trade and transport, and the land along the river bank were each exploited separately for their utility to the settlers called Pākehā by the local people, and parcelled out to individual ownership, even as the indigenous inhabitants were being pushed to the brink. This was completely against the traditional belief that the river was a single and indivisible entity, and not something to be owned. The tribes believed that rivers resources could be used but only the people who contributed to the community had the right to benefit. Under Māori belief, all things have mauri – a life force and personality. When the river’s water quality was degraded, the mauri of the river wasn’t respected, in turn affecting the mauri of the local people, who relied on the river to sustain them. The local people protested, and even initated legal action to claim an independent identity and right for the Whanganui River. The earliest of such petitions date back to 1873.

The case went on through the century and into the next. Tribunals were set up and hearings were conducted. In 1999 the Tribunal agreed that the river was a treasure, but that the local people did not have legal rights over the river. Once again, the litigation stalled. It took another two decades to gain legal recognition for the river itself. The local people, many who were descendants of the original litigants, continued their fight. The case went on to become one of New Zealand’s longest-running court cases.

Finally on March 15, 2017, after over 160 years of negotiation, Whanganui gained “legal status as a person.” The river henceforth will be considered as a living entity. This means that polluting or damaging the river is now legally equivalent to harming a human. Two representatives from the Māori tribes can speak on the river’s behalf, and it can be represented in court cases in an arrangement similar to a legal trust.

The Whanganui River became the world’s first natural resource to be granted its own legal identity, with the rights, duties, and liabilities of a legal person. Having the river recognised as a legal person means that harming it is the same as harming the tribe. If there is any kind of abuse or threat to its waters, such as pollution or unauthorised activities, the river can sue. It also means it can own property, enter contracts and be sued itself.

The legal identity reinforces the deep and inalienable connection that the Māori have to the river, which they consider to be an ancestor, and acknowledges their inherent role in maintaining its well-being. The river continues to be the font of their spiritual sustenance and renewal. It is a caregiver, a guardian, and a totemic symbol of unity.

This case is also indicative of a growing movement called Rights of Nature. This initiative which was launched in 2010 is a broad alliance of civil society organizations in partnership with governments, Indigenous Peoples, members of the scientific community, and future generations delegations.

The Rights of Nature model seeks to recognize Nature and her elements as rights holders, providing them with a voice through representation, and reorienting western law around principles of relationship, interconnection, reciprocity, responsibility, and the recognition that all Earth’s beings, ecosystems, and components have fundamental rights to exist, thrive, and evolve.

The movement is committed to advocating, accelerating, and escalating the global adoption and implementation into legal systems of the Rights of Water Ecosystems (e.g. rivers, mangroves, ocean, and others) and in general, the Rights of Nature.

The Whanganui River which became the first waterway in the world to be granted legal personhood, provided a boost to the movement which is today active in several parts of the world. It seeks to repositioning people and Nature as members of a collective whole working together towards a shared vision of a healthy and livable planet, promotes holistic water management approaches.

Fever Tree

~ millennialmatriarchs ~ Leave a comment

Clay tablets from Mesopotamia mention this deadly disease. Indian writings of the Vedic period (1500 to 800 BC) call it the ‘king of diseases.’ Traces of the disease have been found in remains of bodies from Egypt dating from 3200 and 1304 BC. The 270 BC Chinese medical canon has documented the disease’s headaches, chills, fevers and periodicity. The Greek poet Homer (circa 750 BC) mentions it in The Iliad, as do Aristotle (384-322 BC), Plato (428-347 BC), and Sophocles (496-406 BC) in their works.

The disease? None other than malaria, a disease that has taken its toll on not only humans down the ages, but our Neanderthal ancestors too. In the 20th century alone, malaria claimed between 150 million and 300 million lives, accounting for 2 to 5 per cent of all deaths!

Many have been the scientists who spent their lives trying to understand malaria. Charles Louis Alphonse Laveran (1845-1922) a French army doctor during the Franco-Prussian played a key role. He as the first to postulate that malaria was not spread by bad air, but rather that ‘Swamp fevers are due to a germ’. He was also the earliest scientist to detect crescent-shaped bodies in the blood of affected individuals, and then the four stages of the development of the parasite in the blood. These findings were confirmed by Camillo Golgi. Dr. Charles Ross and India played a huge part in the unravelling of the whole cycle and Ross received the Nobel Prize for discovering the mosquito-stages of malaria.

The story of uncovering the cure for malaria has been dramatic too. For centuries, when no one had a clue what caused malaria, treatments included blood-letting, inducing vomiting, and drastic things like limb amputations, and boring holes in the skull. Herbal medicines like belladonna were used to provide symptomatic relief. 

Cinchona-nitida-quinine
Cinchona Tree whose Bark yields Quinine

But the cure strangely came from South America—a region not originally plagued with the diease. It was probably brought from the outside around the 16th century. The native Indians were the first to discover the cure. The story goes that an Indian with a high fever was lost in the Andean jungles. Desperate with thirst as he wandered the jungles, he drank from a pool of stagnant water. The taste was bitter and he thought he had been poisoned. But miraculously, he found his fever going down. On observation, he found that the pool he had drunk from had been contaminated by the surrounding quina-quina trees. He put two and two together, and figured that the tree was the cure. He shared his serendipitous discovery with fellow villagers, who thereafter used extracts from the quina-quina bark to treat fever. The word spread widely among the locals.

It was from them that Spanish Jesuit missionaries in Peru learnt about the healing power of the bark between 1620 and 1630, when one of them was cured of malaria by the use of the bark. The story goes that the Jesuits used the bark to treat the Countess of Chinchon, the wife of the Viceroy who suffered an almost fatal attack. She was saved and made it her mission to popularize the bark as a treatment for malaria, taking vast quanitities back to Europe and distributing it to sufferers. And from then, the use of the powder spread far and wide. It is said that it was even used to treat King Louis XIV of France.

The tree from which the bark came was Cinchona, a genus of flowering plants in the family Rubiaceae which has at least 23 species of trees and shrubs. These are native to the tropical Andean forests. The genus was named so after the Countess of Chinchon, from the previous para. The bark of several species in the genus yield quinine and other alkaloids, and were the only known treatments against malaria for centuries, hence making them economically and politically important. It was only after 1944, when quinine started to be manufactured synthetically, that the pressure on the tree came down.

Not unusually, the tribe who actually discovered it is forgotten. The medicine came to be called “Jesuit Powder’ or ‘Chincona powder’ or “Peruvian powder’. Trees in the genus also came to be known as fever trees because they cured fever.

May the many indigenous community, their knowledge and their practices which are at the base of so many medicines today get their due recognition, credit and due.

Private Gardens for Public Pleasure

~ millennialmatriarchs ~ Leave a comment

Last week, we delved into the making of the Butchart Garden in Victoria, Canada—a private garden which is completely open to the public. This is not common. For the most part, public gardens are public, and private gardens are private—open only to the enjoyment of the owners, their families and friends.

A public garden is defined by the American Public Gardens Association as: “An institution that maintains collections of plants for the purposes of public education and enjoyment, in addition to research, conservation, and higher learning. It must be open to the public and the garden’s resources and accommodations must be made to all visitors. Public gardens are staffed by professionals trained in their given areas of expertise and maintain active plant records systems.”

On the other hand, a private garden is ‘a type of Urban Green Spaces Areas in immediate vicinity of private (privately owned or rented) houses, cultivated mainly for ornamental purposes and/or non-commercial food production’ and is not usually open to the public.

While Jennie Butchart, creator of the Butchart Gardens was clear right from the start that she wanted as many people as possible to see and enjoy her gardens, not all owners have been so open. Or even if they wanted to, didn’t know how to go about it. But that would be such a loss, because some of these private gardens are spectacular.

And hence, the various initiatives in many parts of the world which try to make private gardens accessible to the public.

For instance, in the US, the Garden Conservancy organizes Open Day programmes. This institution is a nationwide community of gardeners and garden enthusiasts who teach and learn about gardens. Believing that there is no better way to improve as a gardener than by seeing and experiencing firsthand a wide range of gardens, they organize these Open Days, which since 1995, have seen ‘more than 1.4 million visitors into thousands of inspired private landscapes—from urban rooftops to organic farms, historic estates, to innovative suburban lots—in 41 states’. These events are curated and ticketed and open up some of America’s best private gardens to the public for a few days. The organization even brings out an annual publication—‘The Garden Conservancy’s Open Days Directory’ This is a yearly guide to hundreds of private gardens across the United States. The directory includes information on the gardens’ types, such as organic, scenic, or historic, and how and when they can be visited.

In the UK,  London Parks & Gardens organizes the Open Gardens London event every year, helping visitors enjoy hallowed private London gardens including roof gardens, city farms, allotments, spaces steeped in history, and much more. A ticket to the event gives visitors access to every garden on display across the whole weekend, with children under 12 allowed in for free!

Under the Open Gardens South Australia programme, garden owners generously open their gardens for a weekend. The NGO helps owners plan and promote their opening. Some of the ticket money is usually donated to a charity of the owner’s choice

In Ireland, the Gardens Open initiative of Garden.ie lists around 300 gardens open for visiting, some year-round, others by appointment.

Mughal Gadens

The Rashtrapati Bhavan gardens, previously known as the Mughal Gardens are not private. However, they are not open to the public all the time. Constructed by Sir Edwin Lutyens in 1917 in the traditional Persian Charbagh style the Gardens were renamed Amrit Udyan in 2023. The 12-acre beautifully cultivated gardens are open to visitors in Feb-March and Aug-Sept every year and a popular tourist spot in New Delhi.

India has some large public gardens, but no well-known large private gardens—certainly none open to the public. Maybe it is time for some people with the means and the green thumbs to create such green oasis in our crowded, polluted, frantic cities. That would be social responsibility indeed!
