Blue harvest – Inland fisheries as an ecosystem service – A report by UNEP
The report highlights the integrative ecosystem approach to inland fisheries. Posted on 24 Aug, 2011 11:34 AM

CoverThis 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.

This document presents the final report of the Keystone Foundation’s Small Wetlands Programme of IUCN-The Netherlands Committee. Posted on 02 Aug, 2011 07:48 PM

The initiative on hill wetlands in the Nilgiris Biosphere Reserve is supported through this. The area is located at the junction of the Eastern Ghats and the Western Ghats, or Sahyadris, the two prominent mountain ranges that run almost parallel to the coastlines of Peninsular India and is home to indigenous forest people and is a rare repository of mountain biodiversity.

The Nilgiris is home to unique wetlands that are the source of sustenance of numerous animals and human communities. Wetlands are among the more important reservoirs of biodiversity that nature has painstakingly crafted over millions of years.

Farmers groups conserve traditional rice varieties in Bastar region of Chhattisgarh
The Bastar region was once famous for over 20,000 rice varieties. These are now under threat. Dharohar Samiti, a farmer's organization is working to promote agro bio-diversity conservation and secure livelihood and nutrition to farmers. Posted on 28 Jul, 2011 03:17 PM

Farmers groups conserve traditional rice varieties in Bastar region of Chhattisgarh Chhattisgarh is traditionally known as the Rice Bowl of India. Over 20,000 rice varieties have been recorded in the region. These are a result of centuries of rice farming by indigenous communities through selection and adaptation to a variety of soil, water and micro-ecosystems conditions including predators.

Today these varieties are being lost with market forces promoting so called high-yielding varieties and synthetic fertilizer and pesticide-based agriculture that focuses only on yield, as well as the general but incorrect perception of traditional varieties as low yielding. There has also been tremendous loss of traditional knowledge associated with traditional agro-ecosystems and production practices.

CoverThis publication by International Centre for Integrated Mountain Development (ICIMOD) deals with Kailash Sacred Landscape Conservation Initiative (KSLCI), a project that seeks to conserve and sustainably manage a highly unique and special landscape through the application of trans-boundary ecosystem management approaches.

This region, like much of the rest of the Hindu Kush-Himalayas, faces many challenges, not the least of which are global warming, globalisation and environmental degradation. The Kailash region is considered sacred to five major religions and to a large number of people in Asia and throughout the world. This area is historically, ecologically, and culturally interconnected and is the source of four of Asia’s most important rivers.

The KSLCI is an attempt on the part of the three neighbouring countries of India, China and Nepal to join hands to help preserve the unique biological diversity, the many ecosystem goods and services, and the value-based cultural heritage of one of the most revered and sacred landscapes in the world.
