The Long-Term Ecological Observatories (LTEO) Program was introduced by the Ministry of Environment, Forests, and Climate Change (MOEFCC). This multi-institutional, interdisciplinary effort will help policymakers at the national and regional levels better understand how climate change will affect India's varied ecosystems and taxa.

The initiative covers a number of areas, including soil, forests, grasslands, invertebrates, fish, herpetofauna, birds, animal movement, and marine ecosystems. This article will explain to you about Long Term Ecological Observatories (LTEO) which will be helpful in preparing the Environment Syllabus for the UPSC Civil Service exam.

What is Long Term Ecological Observatories (LTEO)?

• Through a network of scientific institutions, the LTEO Programme aims to understand the biophysical and anthropogenic drivers of ecosystem change in the selected biomes, as well as their effects on social-ecological responses.
• Among the activities are experimental work to assess changes in structure and function in natural ecosystems, identification of patterns and drivers of change in natural ecosystems through monitoring populations of fresh water fish, birds, mammals, herbivores and carnivores, animal movements, soil processes in forests and grasslands, biophysical climatic variables, and so on.

What is the need of LTEO?

To address the following needs, the Government of India's Ministry of Environment, Forests, and Climate Change has launched the Long-Term Ecological Observatories (LTEO) programme as part of the country's Climate Change Action Programme.

• Global climate change caused by humans is now accepted as an undeniable fact. The state of knowledge on the projected effects of climate change, on the other hand, remains highly variable.
• Countries such as India have been identified as being particularly vulnerable to the effects of climate change due to their reliance on climate-dependent resources such as agriculture, water, and forestry.
• Because of the large proportion of the population that is at risk, as well as a lack of fine-scaled information on which to base mitigation and adaptation measures, India may face major threats as a result of projected climate changes.
• Information is especially needed on how climate change is likely to alter the distribution and quality of natural ecosystems and resources, as well as the effects on people's livelihoods.

LTEO - Features

• The Climate Change Division of the Ministry of Environment, Forest and Climate Change, Government of India, administers and manages the LTEO initiative.
• The network of scientists working on the program was from the institutions and organizations dedicated to science all around the nation.
• Each site's study is overseen by a local organization with easy access to the location, or by an organization or research group with a sizable research presence and resources there.
• The Ministry of Environment, Forest, and Climate Change has established institutions to handle site-level logistics and the national scientific endeavor.
• A Coordination Cell of the Indian Institute of Science's Centre for Ecological Sciences oversees the coordination of the national program.
• The first phase of the LTEO Programme entails establishing a network of field sites to assess the health of the country's eight different biomes, namely the Western Himalaya, Eastern Himalaya, North-Western Arid Zone, Central Indian Forests, Western Ghats, Andaman & Nicobar Islands, Jammu & Kashmir, and Sundarbans.

LTEO - Goals

• Understanding the biophysical and anthropogenic drivers of ecosystem change and their effects on social-ecological responses is the primary foundation of the Long Term Ecological Observatories (LTEO) initiative.
• The targeted goals of LTEO are:
• Through extensive, interdisciplinary research, to comprehend the ecology of key biomes and social ecosystems at various spatial and temporal dimensions.
• To educate the public, policymakers, and the scientific community about the causes of climate change and its effects on social-ecological systems.
• To support environmental education and training in India through extensive social-ecological research and monitoring.

LTEO - Program Highlights

• Through consistent, ongoing financing for climate change research, students and young scientists will also receive training as part of this program.
• Additionally, the project will assist the nation in developing its own scientific database in this crucial area without relying on studies conducted abroad.
• Further, long-term scientific monitoring of the environment's grasses, mammals, birds, fishes, and insects will be done.
• It will also give its scientists the opportunity to participate in global projects related to the issue and to offer empirical evidence regarding the effects on various ecosystems.

LTEO - Bird Symposium

• For assessing the health of ecosystems, birds are crucial indicator taxa.
• On March 26 and 27, 2021, an online symposium was held by the LTEO Bird theme in collaboration with CEDAR, Bird Count India, and the Nature Conservation Foundation.
• The symposium on "Bird Monitoring in India" recognized key studies in this area and invited participants to share their work on a single stage.
• A discussion on the "Future of bird monitoring in India" was also held during the symposium.
• Inadequate training, permissions, motivation, communication, focus on less well-studied species, diversity, and inclusiveness, and other issues were discussed as a result.

Significance of Ecology

• Ecology enables us to comprehend the impact of our actions on the ecosystem.
• It demonstrates to individuals the degree of environmental devastation we inflict.
• The destruction of land and the environment has resulted from a lack of understanding of ecology.
• Certain species have also become extinct or endangered as a result of it. Dinosaurs, white sharks, mammoths, and so on.
• As a result, studying the environment and creatures aids us in protecting them from harm and danger.
• Ecological knowledge allows us to determine which resources are required for the survival of various organisms.
• For their growth and development, all creatures require energy. Due to a lack of ecological awareness, energy resources such as light, nourishment, and radiation are over-exploited, resulting in their depletion.

Conclusion

A number of developed and developing nations, including India, are working on the LTEO Programme. Thus, through a network of academic institutions, the Long Term Ecological Observatories considerably assists in understanding the biophysical and anthropogenic drivers of ecosystem change in the selected biomes and their effects on social-ecological responses.
