Water Productivity

The international journal “Paddy and Water Environment” has brought out a special issue in March 2011 (Volume 9, Number 1) on “Paddy and Water Management with the System of Rice Intensification (SRI)” which brings together the results of formal research on SRI in a number of countries (Part I) and also reports on initiatives by government agencies, NGOs, universities, or the private sector, bringing knowledge of SRI to farmers in a wide range of agroecological circumstances (Part II). It has six articles and nine technical reports from Afghanistan, China, the Gambia, Kenya, India, Indonesia, Iraq, Mali,  Pakistan, Panama, and Thailand as well as several review articles.

The System of Rice Intensification (SRI), developed in Madagascar almost 30 years ago, modifies certain practices for managing plants, soil, water, and nutrients with the effect of raising the productivity of the land, labor, and capital devoted to rice production. Certain production inputs are reduced—seeds, inorganic fertilizer, water, and fuel where water is pumped—with increased yield as a result.

The paper by Challenge Programme on Water and Food (CPWF) attempts to assess and improve water productivity in conservation agriculture systems in the Indus-Gangetic basin, in which during the past 40 years an intricate mosaic of interactions between man & nature, poverty & prosperity and problems & possibilities has emerged. Rapid expansion in agricultural water use is a common theme across these interactions and access to water is central to the livelihoods of the rural poor.Read More

Earth Policy Institute, is a non-profit environmental research organization dedicated to providing a vision of an eco-economy and a roadmap on how to get there. The Institute was founded in 2001 with the following goals: 

• to provide a global plan (Plan B) for moving the world onto an environmentally and economically sustainable path
• to provide examples demonstrating how the plan would work, and
• to keep the media, policymakers, academics, environmentalists, and other decision-makers focused on the process of building a Plan B economy.

The basic research of the Institute has been published in the form of seven books:Read More

This paper introduces a theoretical model to examine farmers’ response to changes in power tariff and water allocation regimes vis-a-vis energy and groundwater use. The author begins by explaining the context as one where the existing direct & indirect regulations and direct management interventions have been ineffective in arresting groundwater depletion. Also, there is an absolute paucity of sufficient empirical data to compare and analyze the differential impacts of different levels of pricing of electricity, and groundwater rights allocations on water and energy productivity.

The paper presents a review of farm sector pricing theories and thereafter analyses the potential impact of different modes of electricity pricing on productivity of groundwater use.Read More
