Book Description
This paper attempts to understand gender issues in micro-irrigation technology by exploring the dynamics of gender, water and rural livelihoods. Based on an empirical study in the rural areas ofWest Nepal undertaken in 2003, the paper assesses the socioeconomic impact of drip-irrigation systems on men and women􀂶s lives. A combination of participatory research tools, participant observationand secondary sources were used to generate data. The study revealed that women extensively contributed to vegetable farming under the drip-irrigation systems. The total time (mean hours) spent by women in vegetable production is significantly higher than those spent by their male counterparts. The benefit cost analysis of vegetable farming has shown overall viability in terms of net present value, benefit cost ratio, internal rate of return and payback period. Based on the study findings, thepaper suggests that similar technological interventions could be considered in places of similar socioeconomic and biophysical characteristics to help empower rural women. Finally, the paper raisessome significant questions in relation to rural livelihoods and womens entitlements.

Book Description
This book aims to bring forth and address the major issues confronting the irrigation sector of India and also to suggest policy pointers to sustain it. As the policy and reform canvas is large for a huge and diverse country, this book has particular focus on the most important and immediate issues and future options. The chapters not only focus on new research, in-depth analysis and technical details, but also provide a balanced review of the state of irrigation sector and comprehensive presentation of major issues, challenges and future options. With the presentation of in-depth analysis and synthesis of available knowledge, the work can act as a handbook for major irrigation water issues, actual policy changes, and potential reform that could turnaround the sector. Given the temporal and spatial data analysis of the irrigation sector, this book will be effective and useful as a research and teaching tool to students and researchers both in India and globally. Besides its professional audience within the academic, research and policy community, the non-technical format of the book will appeal to a general audience in the media, policy, and donor circles

Book Description
This book uses resource economics costing approaches incorporating externalities to estimate the returns for the country's irrigation, and demonstrates how underestimating the cost of water leads farmers to overestimate profits. The importance of the subject can be judged in light of the fact that India is the largest user of groundwater both for irrigation and for drinking purposes, pumping twice as much as the United States and six times as much as Europe. Despite water's vital role in ensuring economic security for the nation and farmers alike by supporting more than 70% of food production, water resource economists are yet to impress upon farmers and policymakers the true value of water and the urgent need for its sustainable extraction, recharge and use. In an endeavor to promote more awareness, the book further delineates the roles of the demand side and supply side in the economics of irrigation, and explains how the cost of water varies with the efforts to recharge it, crop patterns, degrees of initial and premature well failure, and degrees of externalities. It also discusses the importance of micro-irrigation in the economics of saving water for irrigation, estimating the marginal productivity of water and how it improves with drip irrigation, the economics of water sharing and water markets, optimal control theory in sustainable extraction of water, payment of ecosystem services for water, and how India can effectively recover. In closing, the book highlights the role of socioeconomic and hydrogeological factors in the economics of irrigation, which vary considerably across hard rock areas, and the resulting limitations on generalizing.

Book Description
This book takes stock of micro irrigation systems (MIS), the technological intervention in India’s agricultural and water management sectors, over the past couple of decades. Based on empirical research from the major agriculturally dynamic states, viz., Gujarat, Rajasthan, Maharashtra, Tamil Nadu, Andhra Pradesh and Karnataka, the book provides a nuanced understanding and objective assessment of the implementation and adoption of MIS across these states. It addresses several of the questions related to adoption and impacts of MIS in India. On the adoption side, the key question that the book addresses is which segment of the farming community adopts MIS across states? The impacts analysed include those on physical, agronomic and economic aspects. At the macro level, the question being asked is about the future potential of MIS in terms of saving water from agriculture and making more water available for environment. The book also addresses the question of the positive/negative externalities and real social benefits and costs from the use of MIS, a major justification for heavy capital subsidies for its purchase by farmers. It also brings out certain critical concerns pertaining to MIS adoption, which need to be addressed through more empirical research based on longitudinal panel/ cross sectional data. The book would be of great use to researchers (agricultural water management, irrigation economics), students of water resource engineering, irrigation engineering and water resources management, as well as to policy makers and agricultural water management experts – national and international.
