Bioremediation, its applications to contaminated sites in India - A state of the art report by Ministry of Environment and Forests
Bioremediation is emerging as an effective innovative technology for treatment of a wide variety of contaminants and is an invaluable tool box for wider application in the realm of environmental protection. Bioremediation approach is currently applied to contain contaminants in soil, groundwater, surface water, and sediments including air. These technologies have become attractive alternatives to conventional clean-up technologies due to relatively low capital costs and their inherently aesthetic nature.  It includes phytoremediation (plants) and rhizoremediation (plant and microbe interaction). Rhizoremediation, which is the most evolved process of bioremediation, involves the removal of specific contaminants from contaminated sites by mutual interaction of plant roots and suitable microbial flora.  The report documents the existing knowledge for the benefit of regulators, who evaluate the quality of environment and for practitioners, who have to implement and evaluate remediation alternatives at a given contaminated site. It is expected to provide basic understanding of the bioremediation mechanisms to the reader. The technical descriptions provided in this document concentrate on the functioning mechanisms: phytosequestration, rhizodegradation, phytohydraulics, phytoextraction, phytodegradation, and phytovolatilization.

Groundwater scenario in major cities of India – A report by Central Ground Water Board
It covers varying groundwater scenarios in the country including the highly developed metros, the hilly region, the coastal cities, the cities tapping unconsolidated and hard rock aquifers. The report briefly describes the administrative set up, status of water supply and demand, groundwater scenario, feasibility of rainwater harvesting and groundwater development strategy. It is an updated version of an earlier report on “Groundwater in urban environment in India” (2000). Since then, groundwater regime, urban demography and water demand have changed enormously. This report will form a scientific base for an in-depth understanding of urban groundwater system including aquifer geometry, water level behavior and groundwater quality. The possibility of artificial recharge to rejuvenate the urban aquifers has also been discussed.

Ecologically sound, economically viable community managed sustainable agriculture in Andhra Pradesh – A report by Society for Elimination of Rural Poverty and World Bank
This report by Society for Elimination of Rural Poverty and World Bank deals with Community Managed Sustainable Agriculture (CMSA) in Andhra Pradesh.  The paper also analyses the initial results of economic and environmental impact of CMSA, distills the key lessons learned from the Andhra Pradesh experience, and draws possible implications for future. To address the adverse impacts of green revolution, the alternative approach to manage agriculture i.e., CMSA is being tested and practiced in the State. The CMSA approach replaces the use of chemical pesticides with a combination of physical and biological measures—including eco-friendly bio-pesticides—and complements it by adopting biological and agronomic soil fertility improvement measures leading to reduced use of chemical fertilizers.

Hydrological and farming system impacts of agricultural water management interventions for sustainable groundwater use in North Gujarat - A paper by Institute for Resource Analysis and Policy
The report by Institute for Resource Analysis and Policy (IRAP) and Society for Integrated Land and Water Management (SOFILWM) presents the findings of a research study undertaken in north Gujarat region, an area which has been undergoing significant changes in its farming systems as a result of several developmental interventions. The study looked at a project initiated by IWMI and managed by SOFILWM in which water-efficient irrigation devices, water-efficient crops and land management practices were introduced among farmers in an effort to help them cut down groundwater use in irrigated agriculture without adversely affecting the economic prospects of farming.

Pampered views and parrot talks – In the cause of well irrigation in India – A paper by Institute for Resource Analysis and Policy
 It is widely held that surface irrigation is becoming increasingly irrelevant in India’s irrigation landscape in spite of increased investments, and therefore future investments in irrigation should be diverted for well irrigation.

Jalyatra: Exploring India's traditional water management systems
Jalyatra - Exploring India's traditional water management systems, by Nitya Jacob is an ecological travelogue that looks at links between water, society and places It describes in detail what existed, how it fitted into the socio-cultural milieu and was appropriate for the local climate and geography. It then examines reasons for their decline, as indeed most have, in recent decades. While recording the dismal state of traditional systems, the author stumbles upon small initiatives that have brought about significant transformation across regions. It refers to noisy hidrums and gharaats, the river-run flour mills of Uttaranchal, the technologies whose potential has yet to be fully realised. It looks at water harvesting structures of southern India—the eris and ooranis. However, it admits that the average person is singularly uninterested in protecting the environment. Jalyatra captures the efforts of NGOs and enlightened individuals striving to revive these systems. It makes the case for a mass movement to revive traditional water management systems, especially village ponds, across the country as the way to ensure water security in India. In Chambal, the author meets Brij Mohan Gujjar, dacoit turned water conservationist, who is doing valuable work on the check dams designed to control the flow of water in the ravines; and in Shillong, Lan Potham shows him the uses of the easily available bamboo to construct the shyngiar which irrigates his areca nut plantation.

Gujarat’s agricultural growth story: Reality check and important lessons for water management – A paper by Institute for Resource Analysis and Policy
 The agricultural ‘growth’ seen in the recent past in Gujarat is nothing but a good recovery from a major dip in production occurred during the drought years of 1999 and 2000, because of four consecutive years of successful monsoon and bulk water transfer through the Sardar Sarovar project. The real ‘miracle growth’ in Gujarat’s agriculture appears to have occurred during the period from 1988 to 1998.

NREGA and rural water management in India: Improving the welfare effects – An occasional paper by IRAP
NREGA is being eulogized by many in the academic, development and policy arena as a “silver bullet” for eradicating rural poverty and unemployment, by way of generating demand for productive labour force in villages and private incentives for management of common property resources.

Global equatorial sea-surface temperatures over the last 150,000 years: An update from foraminiferal elemental analysis – A paper in Current Science
 Solar insolation changes are amongst various factors that affect sea-surface temperature, which in turn modulate global climate. Out of all the oceanic regions, equatorial region receives the maximum solar insolation and thus is the locale for the warmest waters. However, how the equatorial sea-surface temperature affects global climate, is still not clear.
