Ecology and Environment

The focus is concepts that capture the hybridity of irrigation systems as complex systems, and cross the boundaries of the natural and social sciences. 

Changing climate, loss of native forests, disappearance of biodiversity, water shortages, desertification, the reduction of natural soil fertility — all add to the scenario of a world with increasingly complex environmental challenges.

The concept of Payment for Ecosystem Services (PES) has emerged as a challenge to the all-too-prevalent tradition of taking the Earth’s natural resources for granted. PES highlights a global continuum, illustrating the relationship between our lifestyles, the demands associated with our production and consumption patterns, and the effects those demands have on close or distant ecosystems.

This report by Institute of Financial Management and Research (Madras) and Indian Institute of Technology (Madras) deals with the impact of sea level rise on major infrastructure, ecosystems and land along the Tamil Nadu coast.

The Tamil Nadu coastline is about 1,076 km, with thirteen coastal districts, and it forms a fairly large contiguous and narrow coastal strip dotted with fragile ecological features and rampant development activities. There are major, existing and proposed, economic and infrastructure developments, including ports, power plants, highways and even airports, which are being planned very close to the shoreline along India’s coast.

This report by the Indian Institute of Technology (Delhi) for the Ministry of Environment and Forests (MoEF) deals with the scope, structure and processes of the proposed National Environment Assessment and Monitoring Authority (NEAMA). The findings and recommendations of the project are based on an analysis of various research and committee reports, a critical review of the implementation of EIA notification 2006, CRZ notification 1991 & CZM Notification 2010, and a review of the international practices.

This report by United Nations Environment Programme (UNEP) reviews the importance of inland fisheries as an ecosystem service, the pressures upon them, and management approaches to sustain them and thus helps inform future approaches to conservation and management of freshwater ecosystems.

There is an urgent need for major investment in policy and management approaches that address the direct and indirect drivers of aquatic ecosystem degradation and loss of inland fisheries taking into account their role in sustainable development and human well being. The UNEP Ecosystem Management Programme (UNEP-EMP) provides an effective framework for pursuing this challenge.

Agriculture is the main occupation of the tribe and they have a unique way of knowing plantation season for different crops by observing the flowering of some plants. The indicator plants are peach, wild cherry, camel foot and dancing girl.

This paper published in the Indian Journal of Traditional Knowledge highlights the findings of a study that correlates the indigenous knowledge and scientific knowledge in assessing the nutrient availability status of agricultural soil as practised by the Nyishi tribes who use visual properties such as colour, texture and topographic positioning of land/terrain.

This paper published in the Indian Journal of Traditional Knowledge makes an attempt to record the fisheries related indigenous technological knowledge in terms of fishing crafts and gears used in river Krishna.
