Adivasis' rights over forest lands diminishes

Land use changes  hydrologic system and have potentially large impacts on water resources. An assessment in an area with seasonally limited water availability and which is subject to rapid socio- economic development and population growth will provide an exemplary view on the local impacts of major recent developments in India. In this backdrop this paper analyzes past land use changes between 1989 and 2009 and their impacts on the water balance in the Mula and Mutha Rivers catchment upstream of Pune. The aim of the paper is:

• assess the land use changes between 1989/1990 and 2009/2010
• analyze the impacts of these changes on the long-term water balance components in the Mula and Mutha Rivers catchment upstream of the city of Pune.

Groundwater contamination is a serious, but relatively ignored issue in the country. This contamination occurs in either through geogenic or anthropogenic means. Fluoride contamination is one such example of geogenic contamination that is widely found in the Kolar district of Karnataka. However, the fluoride levels in the town of Mulbagal are lower than those in the surroundings. Earlier, a study was conducted on the impact of pit toilets on the groundwater in the area. The present paper investigates the presence of any link between these two phenomena.

This handbook by Central Water Commission aims to provide necessary guidance to the field engineers in the state and central for design, appraisal, construction and monitoring of the flood management works covering all the relevant BIS codes, design manuals, guidelines, technical specifications for construction materials and practices etc. to meet new challenges in the flood management in India.

This guideline is prepared by the Centre of Excellence in the area of Decentralized Wastewater Management, in the Department of Civil Engineering at Indian Institute of Technology, Madras, which comes under Ministry of Urban Development

The February edition of the TRINet has the following highlights: 

The city corporation of Madurai decides to power all the parks with solar energy.

In the recent times visual representation has acquired significant attention. These are in forms of photographs, sketches and schematic diagrams. At school level they are helpful in introducing abstract concepts in science. For this purpose they need to be appropriately integrated in the textbook. In the backdrop of this context this paper in Contemporary Education Dialogue is based on the analysis of the science textbooks of the National Council of Educational Research and Training (NCERT) and the Maharashtra State Board (MSB) for Classes 3–10.
