Framework for valuing ecosystem services in the Himalayas - An ICIMOD technical report
This document by ICIMOD outlines a general framework for economic valuation of ecosystem services in the Hindu Kush-Himalayan (HKH) region Posted on 17 Feb, 2012 12:12 PM

This has been a generic first attempt that can be fine-tuned and customised for each type of ecosystem and each kind of service value. Ecosystem services are defined by the Millennium Ecosystem Assessment as ‘the benefits people obtain from ecosystems'.

Mountains occupy 24% of the global land surface area and are home to 12% of the world’s population. Mountains have an ecological, aesthetic, and socioeconomic significance, not only for those living in the mountain areas, but also for people living beyond them. However, the importance of ecosystem services arising from mountains is not properly recognised. The HKH region is endowed with a rich variety of gene pools and species, and ecosystems of global importance. It is a storehouse of biological diversity and a priority region in many global conservation agendas. The region has many unique ecosystems that play a critical role in protecting the environment and in providing livelihoods for much of Asia and beyond.

Climate change in the Hindu Kush-Himalayas -The state of current knowledge - A book by ICIMOD
This book by ICIMOD presents an analyses of the available data on climate change in the Hindu Kush-Himalayan region, and identifies persisting insufficiencies in the data. Posted on 16 Feb, 2012 01:10 PM

The Hindu Kush-Himalayan region has had very few resources to develop a detail scientific understanding needed to assess climatological, environmental, and other data in the past and there is very little information upon which a baseline for comparison with the present can be formed and future impacts can be anticipated.

Stress of urban pollution on largest natural wetland ecosystem in East Kolkata - Causes, consequences and improvement

Living rivers, dying rivers: Rivers in the Western Ghats

River stories from Maharashtra: Many morals to learn 

Parineeta Dandekar’s presentation began with an account of some statistics related to Maharashtra, the third largest state in India. Regarding the state of water resources in Maharashtra, she noted that of the five river basin systems, 55 percent of the dependable yield is available in the four river basins (Krishna, Godavari, Tapi and Narmada) east of the Western Ghats. These four river basins comprise 92 percent of the cultivable land and more than 60 percent of the population in rural areas. 45 percent of the state's water resources are from west flowing rivers which are mainly monsoon specific rivers emanating from the Western Ghats and draining into the Arabian Sea.

With 1821 large dams and more in the offing, Maharashtra has the maximum dams in the country (35.7%). However, the proportion of gross irrigated area vis a vis the gross cropped area at 17.8 percent is much lower than the national average of 44.6 percent. The contradictions from the state, which is home to the highest number of dams, were discussed. In nearly 70 percent of the state’s villages (around 27,600 villages), water is either not available within 500 metres distance, or within 15 metres below ground level or when available is not potable (World Bank, Promoting Agricultural Growth in Maharashtra, Volume 1, 2003).

Dandekar discussed the World Bank funded Maharashtra Water Sector Improvement Project (MWSIP) initiated in 2005 whose main components were establishment, operationalisation and capacity building of Maharashtra Water Resources Regulatory Authority (MWRRA); establishment of river basin agencies in Maharashtra; and restructuring and capacity building of the Water Resources Department. The MWRRA Act (2005) has been amended, taking out the clause for equitable water distribution, and granting the Cabinet the rights to have the last say about water entitlements. This has led to a diversion of water for irrigation from the vulnerable, suicide-prone Vidarbha region to thermal power plants. According to Prayas, “entitlements of more than 1500 MCM have been changed from agriculture to industries and cities”.

Looking beyond Durban:Where to from here - An article in EPW
In this paper published in the Economic and Political Weekly, Navroz Dubash argues that 'India needs to re-articulate and enrich its position on equity in climate negotiations'. Posted on 20 Jan, 2012 03:58 PM

The Durban climate negotiations have set into motion new negotiations, with the possibility of re-opening old and contentious issues, while at the same time leaving the global climate regulatory framework unchanged. While disappointing, this does create a possibility of starting anew.
