5 June has been marked annually as World Environment Day (WED). First held in 1973, and led by the United Nations Environment Programme (UNEP), WED is the largest global platform for environmental public outreach and is celebrated by millions of people across the world. This year, 2024, the kingdom of Saudi Arabia is hosting the global celebrations.
The focus of this year’s WED is land restoration, desertification and drought resilience.
As the world is seeing rapid advances in desertification, and land degradation, propelled by climate change, it is useful to go back and see nature’s in-built mechanisms for coping with such conditions.
Plants that grow in arid areas have special ways of dealing with extreme heat or cold, and other desert conditions. Desert plants fall into three categories according to the way they deal with the problem of surviving in arid or extremely arid conditions.
Drought evaders: Plants which remain as seeds in the sand, but are ready to spring up when it rains, to flower quickly, to produce another crop of seeds and die again. These are known as ephemerals.
Drought resisters: Plants which have evolved various ways of storing water, locating underground water or reducing their need for water by such methods as shedding their leaves. These are known as perennials. They manage to live from one rainy season to another.
Drought-endurers: Plants which have the capacity to tolerate drought for a longer period by adapting through condensed growth, small-sized leaves and very deep root system.
These natural adaptations have enabled these plants, over millennia, to grow in some of the toughest of conditions. In turn, these plants have also played an important role in supporting other life, including human life, in desert conditions. Perhaps no plant better exemplifies this than the Khejri tree.
Khejri or Prosopis cineraria is a tree that grows in the dry and arid regions of India and West Pakistan, Afghanistan and Iran where summers are very hot, winters are harsh, and rainfall is scant. It has a variety of common names in different states of India. Khejri or sangria (Rajasthan), jand (Punjab), kandi (Sindh), sami, sumri (Gujarat). Its trade name is kandri.
A moderate-sized evergreen thorny tree, with light bluish-green foliage, its sturdy older branches, and slender tender branches have conical thorns. It sprouts freely from the base, producing a fresh growth of leaves around March. Soon after the new leaves, the small yellow, creamy white flowers appear. These, in turn, give way to pods.
This drought-resister tree has a range of adaptations that enable it to grow well in highly arid and harsh conditions, where other plants cannot survive. It grows on a variety of soils, including moderately saline soils. It has a long and well-developed root system. This serves two purposes; it provides firm anchorage and also aids in obtaining moisture supplies from deep down. Its foliage also helps to absorb moisture from the rains, as and when there is rainfall.
The roots are a life saver not only for the tree, but are equally valuable for the environment in which the tree lives. The extensive root system helps to stabilize shifting sand dunes. The tree is useful as a windbreak shelter, and in afforestation of dry areas. It fixes nitrogen through microbial activity, and its leaf litter decomposition adds organic matter thus rejuvenating poor soils.
Often being the only kind of tree that grows in the arid conditions, the tree also provides much needed shade and shelter to local farmers, as well as livestock. Prosopis cineraria is a much valued fodder tree, which provides nutritious and highly palatable green as well as dry fodder which is readily eaten by camels, cattle, sheep and goats. Its dead leaves are fed to cattle to improve milk yield. Its dry pods are also nutritious animal feed. The pods are also eaten, in green as well as dry forms, by people who have scant access to a variety of fresh vegetables for much of the year.
The tree’s wood is suitable for construction, and is used locally for numerous purposes including making agricultural implements and tool handles, water pipes, yoke and spokes of carts. The high calorific value of the wood also makes it an efficient fuel wood. The bark of the tree is dry and acrid with a sharp taste. The bark extract is believed to have anti-inflammatory properties, and is used in traditional medicine to treat rheumatism, cough and colds, and asthma, as well as scorpion sting. The pod is also believed to have astringent properties.
A popular saying in the Thar desert encapsulates the value of the khejri. Death will not visit humans, even at the time of famine, if they have a khejri, a goat and a camel, since the three together help sustain humans even under the most trying conditions.
Thus for millennia the people of the Thar have revered the khejri as such a critical part of their lives. And they have given up their own lives to save the trees that sustain their lives.
Nothing highlights this better than the story of Amrita Devi and the Bishnois, or Twenty-niners, a sect that lived by simple tenets: Do not cut any green tree, do not kill any animal or bird, respect every living being, it has as much right to life as we humans do.
Amrita Devi’s story dates back to 1730. The then Maharaja of Jodhpur, Abhay Singh, wanted to build a new palace for which he required wood. He sent his soldiers to a village to cut down some khejri trees. But this was a Bishnoi village. For hundreds of years, generations of villagers had nurtured and protected their vegetation, land and wildlife. One of the villagers was churning butter when she heard the commotion. Her name was Amrita Devi. She saw the men sharpening their axes and her mind flashed back to her childhood. She remembered how, every morning, she would respectfully greet all the khejri trees and choose a special one for that day; she would hug it and thank it for all the gifts that it gave her and her people. Every child in the village had their own special tree.
Now the trees were in danger. Amrita Devi ran and confronted the axe men. She pleaded with them: “Leave our trees. They are our brothers and sisters, our village protectors. They are the breath of life, the water we drink, and our food.”
The axe men paid her no heed. They continued with their task. Amrita Devi hugged a tree. “Chop me first” she said, “take my life and leave my tree.” The axe men tore her away, but Amrita Devi was back at her tree, clinging for dear life. She did not let go of her tree; the axe men had to chop through her body to get to the tree. No sooner did Amrita fall than hundreds of villagers, young and old, rushed to the trees. Each one hugged a khejri tree. The king’s men continued to chop through them, until 363 people lay dead at the feet of the trees they hugged to save.
When the king heard of the incident, he could not believe that people would lay down their lives for trees. He personally visited the village to meet these people. They said: “The trees can survive without us, but we cannot survive without the trees.” The king was deeply moved the faith and humility of these people. He proclaimed that from then on no Bishnoi village would be called upon to provide timber or wildlife by hunting. Almost three centuries later, the Bishnoi community is intact. The twenty-nine tenets continue to live, even as the khejri trees give life to the land and its people. Amrita’s village came to be known as Khejarli after the trees she gave her life for.
Amrita Devi’s name is synonymous with her sacrifice. In 2001, a national award (the Amrita Devi Bishnoi Wildlife Protection Award) was created in her honour, to recognize people who had contributed to environmental conservation.
This World Environment Day, as the world looks ahead to combatting desertification, it is humbling to look back and remember the story of Amrita Devi and the khejri trees.
