These "before-after" satellite map images from the UNOSAT website depict the impact of the 2004 Tsunami on the Tamil Nadu coast.

This papers models the saline water intrusion in the Bardez taluk of Goa.

The study is replete with hydrogeological maps and data. These include topographic contours, soil, landuse, rainfall, geology, location of observation wells etc.

A member of the PLC Watsan group Dhani behn, has built an Ecosan toilet for herself - one of the first in Gujarat-about a year back. This is one of the best toilets on Ecosan I have seen and the simple and elegant story of the same is hugely impressive. It is located in Bhavnagar Saurashtra - Gujarat. She was part of an exposure visit of PLC WatSan to a MYRADA project in Karnataka implementing ecosan. She has one simple reason for use of the toilet- it's less use of water. Even with a twin pit pour flush about 5 litres of water gets used for a single flush and in a day 20 to 25 litres of water can get flushed by one person. Even this is too much in arid and semi arid Gujarat. The transfer of knowledge has resulted in an elegant solution to an otherwise vexing issue that can be made applicable on a larger scale across the state. There exists tremendous interest in Eco-san from other parts of Gujarat too including the coast with its high and saline water table and the tribal hamlets with its hard rock terrain and the rest with a lot of water shortage.

This post deals with the recommendations and outcomes of the recent workshop on "Mangrove Forest Ecology, Management and Restoration" held at Rajanagar (boundary of Bhitrakanika National park) on 26th-27th November 2008, organized by Action for Protection of Wild Animals (APOWA) and sponsored by Ministry of Environment and Forets, Govt of India. The workshop was attended by 101 participants from the community representatives, teachers and lecturers of coastal schools and colleges, NGOs, CBOs, PRIs, Govt authority, Scientists, researchers, media etc. Witnessing firsthand the rapid devastation of the Orissa's mangrove forest wetlands and their associated coastal ecosystems, the participants, resource persons were recommended to form a network to save the mangroves.

On June 28, 2008, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured these images of Qingdao and the bay of Jiaozhou Wan. It shows the officials and residents of Qingdao (also known as Tsingtao) struggling with a stubborn adversary: algae. The top image is a natural-color image similar to what a digital camera would photograph.

Due to the heat from the Sun the water in the rivers, lakes and Oceans becomes water vapour. As this hot moist air rises into the sky the temperature gets reduced at 7oC per km height in the sky.
