Ecology and Environment

 News from Odia and English (Bhubaneswar internet editions)   news papers are put together at one place to provide an appreciation of Drought in Orissa periodically.

This Drought Update is being circulated among media, decision makers – legislatures, bureaucrats etc. with an aim to catalyze informed and expeditious decisions and actions.

This paper by the Challenge Programme for Water and Food (CPWF) presents a simplified approach to combine remote sensing, census and weather data to analyze basin rice and wheat water productivity (WP) in Indo-Gangetic river basin, South Asia. It presents an innovative approach to combine meteorological data, ground survey, national census with remotely sensed imagery to assess water use, yield, and finally crop water productivity for the Indo-Gangetic rice-wheat cropping system in South Asia. 

How would we judge ecological sensitivity? Scientists view an ecologically sensitive area as an area whose ecological balance, once disturbed, is very hard to restore. Thus, steep Western slopes of Western Ghats, subject to heavy rains and winds, if deforested, are likely to be quickly stripped of soil cover and for ever lose their pristine vegetation. We do have a scientific understanding of the environmental attributes that render areas more sensitive; we also have insights into processes that have resulted in irreversible ecological damage.

This working paper by the Challenge Program for Water and Food explores the intersection between water management, climate change, and adaptation in the Ganges River system, a basin vital to the security, economy, and environment of South Asia. 

Recognizing that an understanding of both the science and the policy of water management, climate change, and adaptation is rapidly evolving, it is not the intention of the paper to encompass all the issues related to these broad fields, but rather to provide a starting framework from which to further develop research questions and priorities for work in water and adaptation.

Amayam island in Kololambu, Edappal panchayath, Malappuram ditstrict, Kerala state which have rich in biodiversity and 40 acres of kol wet land is around the island is also rich in its rare biodiversity. This kol wet land is a part of vembanad backwaters (13,632 hectors) and declared as RAMSAR SITE (No. 1214) in 2002.

Midnight, August 6, 2010: "Link, wake up!  Water is coming in from the roof!"  My mother and I were in Leh, Ladakh, staying at "Eco-Homestay," the house of Mr. Sonam Gyatso and family, in Lower Sankar.  The house was made in a hybrid of traditional and modern construction techniques: the main hall in the house was concrete, while rooms surrounding it were made of sun-dried mud bricks, and roofed with Poplar beams, a mesh of willow branches, and a thick pad of fine clay-like mud.  The house incorporated passive solar building techniques, such as a direct-gain room, and a Trombe wall, and had solar-powered lighting.  It had been raining since evening, and by midnight the clay roof was saturated and began to leak.  

We were in Leh for the express purpose of meeting with Helena Norberg-Hodge, the founder of the International Society for Ecology and Culture, co-founder of the International Forum on Globalization, founder of the Ladakh Ecological Development Group, and founder of the Women's Alliance, Ladakh.  We had learned of her online, seeing an article of hers in CounterCurrents.org, and watching her video "Ancient Futures."  She is the only person who has critically witnessed the "development" of Ladakh, from complete self-sufficiency in an exceedingly fragile eco-system, to the disaster under which it writhes today.  She has seen how "development" pulls people into a money economy, increases the distance between production and consumption,  brings reliance on fossil fuels (especially apparent in Leh where fuel and commodities are trucked in over a hazardous two-day journey from lower altitudes), results in urbanization and rural-urban migration, and brings psychological impoverishment to the people it is inflicted upon.  For 35 years, she has been working to bring safe, stable, and ecologically sound development to the region through her organizations.  Her work today, no longer limited to Ladakh, is focussed on spreading economic literacy among people throughout the planet, educating about the deeper impacts of globalization and today's consumer mono-culture.  Garnered from her years of observation and research, she has an important message for humanity today, which is what prompted us to go and meet her.

This paper by the Institute of Social and Economic Change (ISEC) examines the extent of groundwater dependency and quality status in four South Indian cities viz., Hubli, Dharwad, Belgaum and Kolar cities. Widespread water shortage problems have resulted in increased dependency on groundwater with tapping the resources to unsustainable levels. In Karnataka, out of 208 urban local bodies that come under Karnataka Urban Water Supply and Drainage Board, 41 depend on groundwater.

The study by National Institute of Hydrology attempts to model seawater intrusion using FEFLOW, an interactive finite element simulation system in the coastal area of Bardez taluka in North Goa and evaluate the impact of increasing groundwater development on the phenomenon. Coastal tracts of Goa are rapidly being transformed into settlement areas and the poor water supply facilities have encouraged people to develop their own sources of water by digging or boring wells.

This study by the National Institute of Hydrology deals with simulation of soil moisture movement and determination of groundwater recharge from rainfall in Barchi watershed in the hard rock region of Karnataka using the numerical model, Soil Water Infiltration and Movement (SWIM).

This is a translation from the Nepali of an article that first appeared in Nepal magazine on 11 July 2010. Dipak Gyawali is member of the panel of experts reviewing the Mekong River Commission’s Basin Development Plan and vice-chair of the technical committee of the UN’s World Water Assessment Programme. He was Nepal’s Minister for Water Resources during 2002-03.

Many Nepalis would be shocked to hear that Bhutan will face load- shedding from the coming winter. The citizens of Nepal have, after all, been told for decades that Bhutan has done a great job of developing hydroelectricity, that it has earned significant money by exporting electricity to India, and thus it has been able to achieve the highest per capita income in Southasia. Conversely, Nepal has been ridiculed for wallowing in ‘empty nationalism’ and stirring ‘needless’ controversies over the Mahakali Treaty of 1996 (for water sharing on the Mahakali River) as well as hydropower projects such as the West Seti, both of which involve export of electricity to India.
