Recurring environmental crisises have become a very serious issue today, driven by two major reasons. Firstly, we have not paid adequate and sincere attention to the matter, and, despite discussions, debates, and dialogues, we have not arrived at any concrete solution that can address the issue from local to global levels. The impact of climate change and global warming is evident everywhere—from small communities to the global stage.  

Secondly, there has been a consistent lack of attention to the interconnected verticals of the environment and their scientific measurement. These aspects have rarely been studied in an integrated manner. Four key areas drive ecosystems, with water and forests being the most critical; besides these, soil and air are equally important.  

If we examine the global forest status, more than half of the world’s forests have been degraded or depleted. Unfortunately, afforestation programmes often fail to consider the compatibility of tree species with local climates. To improve survival rates, we frequently plant species that are economically beneficial but climatically unsuitable. For example, Tectona grandis, a species native to Kerala, is being planted in the foothills of the Himalaya. Similarly, under agroforestry, commercial species like eucalyptus and poplar are promoted and used for industrial purposes. Unfortunately, commercial species are prioritised over ecological ones. While the economy is an important factor in forestry, its robustness depends equally on ecologically valued tree species. We must focus on climatic forestry, which better supports soil, water, and air systems. Thorough scientific studies are required to validate climate forest species interconnected with soil, water, and air and compare them with other species.  

The second area requiring scientific intervention is soil status and health. The widespread use of chemical fertilizers has had visible negative impacts, increasing dependence on insecticides, pesticides, and excessive water usage. These practices have also raised concerns regarding human health and hygiene. Although chemical fertilizers cannot be entirely ignored due to food needs, there has been a lack of organised effort to partially replace them with locally available organic alternatives. For instance, different altitudes support different types of trees and are naturally suited to their ecosystem and consumption needs. Leaves from Shorea robusta forests make excellent compost for tuberous crops, conifer forest leaves benefit paddy crops, and oak tree leaves are valuable for vegetables and millets. These natural connections of forest trees, plants, and invading species for different altitudinal matches to respective crop systems have yet to be scientifically validated for wider understanding and use. Since this was overlooked in the past, chemical use continues to rise, even in mountainous regions now. Since water flows from mountains to flat lands, it carries infested soil too, damaging ecosystems downstream.  

Water is another critical concern. All water sources—glaciers, rivers, underground reserves, and water bodies—depend on showers. However, we have not effectively correlated and connected shifting rainfall patterns with various water bodies. Harvesting rainwater through understanding nature’s route and behaviour can help bridge the gap between the availability and crisis of water. This will allow water to be used throughout the year irrespective of changing rain patterns. In order to achieve this, scientific groundwork and connected analyses are lacking in our scientific approaches.  

Glaciers, which are receding rapidly due to rising temperatures, have been the subject of fragmented studies. Evidence suggests that local glaciers can be sustained through high-altitude artificial water-harvesting structures. This may ensure consistent irrigation for farmers locally as well as downstream. Similarly, the health of small tributaries of rain-fed rivers can be improved through investigating alternative recharge methods for watersheds, aquifers, and rivers by following the mechanisms of nature. Studies have shown that even non-forested catchments, when properly managed for water harvesting, can outperform forested areas in water retention and recharge.  

Interestingly, once the water regimes of degraded watersheds are restored, they naturally turn into vibrant ecosystems. Moisture-loving plant species begin to grow, creating habitats and developing food chains that attract wildlife. Scientific evaluation and examination are needed to understand how restoring water bodies can directly rejuvenate the entire ecosystem. This also addresses the issue of forest fires. These fires often start on the dry forest floor and quickly spread from the surface to the canopy. However, introducing water-harvesting structures and water holes in such prone areas raises surface moisture, reducing fire risk. This also encourages the conversion of vegetation from mono-species to multi-species. This process, known as ecological conversion, is a totally new concept for forestry. This approach needs to be subjected to research and development for further use.  

Even the air, which we refer to as Pranavayu, is influenced by forest cover and tree species. The impact of locally adapted trees on air purification and carbon sequestration must be studied in light of the air pollution situation in the country.  

We have disrupted the natural balance due to our poor understanding of ecological processes. It is crucial now to integrate new knowledge and technology with nature science. A dedicated stream of research focused on harmonising the economy with ecology is essential. Serious R&D efforts must be undertaken through collaborative institutional support. Conferences, workshops, and strategic dialogues must explore how such research can be undertaken and implemented.  

This must be one of the verticals in the Prime Minister’s National Research initiative, especially when we are heading towards becoming one of the top five economies of the world. Keeping the economy and ecology together is the challenge now, and this will be possible only when we show equal concern for environmental issues.
