| Increasing water scarcity, rising costs of irrigation subsidies, and general economic liberalization are creating strong incentives for comprehensive water reform with establishment of tradable water rights and the development of markets in these rights. Experiences in Chile, Mexico, and California indicate that water allocation through markets in tradable water rights offers a viable approach to improving the efficiency of water allocation, and should receive serious consideration from developing country policy makers. Laws establishing tradable rights should be simple and comprehensive, should clearly define the characteristics of water rights and the conditions and regulations governing the trade of water rights; should establish and implement water... |

| Sustainable irrigation water management should simultaneously achieve two objectives: sustaining irrigated agriculture for food security and preserving the associated natural environment. A stable relationship should be maintained between these two objectives now and in the future, while potential conflicts between these objectives should be mitigated through appropriate irrigation practices. Lessons learned from unsustainable water management practices around the world demonstrate the necessity—and growing urgency—of applying sustainability principles to water management in river basins where irrigation is a major factor. This paper presents the operational concepts and analytical framework for sustainability analysis of irrigation water management in... |

| In this paper, we conduct two "counterfactual" simulations for the 30-year period 1970-2000-the first holding 1970 crop genetic improvements (CGI) constant and the second presuming the International Agricultural Research Center (IARC) system had not been built. Both these counterfactuals apply to developing countries only. The core estimates on which the counterfactuals are based include country fixed effects , and the key estimates are for the Dietary Energy Sufficiency (DES) equation. DES affects birth rates, death rates, child mortality rates and malnutrition rates, making it possible to "endogenize" population growth in developing countries, in the counterfactuals. Reduced DES levels (from reduced CGI contributions) will lead to more births, more... |

| The sources of production risk are many and diverse in nature. Estimating risk as a black box, without explicit recognition of its sources, can lead to inferior estimates of optimal inputs under risk aversion. In this paper, a method is presented for estimating production functions with measurable stochastic inputs and for generating the parameters of the probability distributions of yield for various environments and input levels. Based on this method, it appears that moderate risk aversion can account for a 6.7 per cent to 16.7 per cent reduction in nitrogen use (relative to the risk-neutral solution) for selected rice producing areas of the Philippines. Estimating optimal inputs without environment specific information about the sources of risk leads to... |

| Increasing competition for water across sectors increases the importance of the river basin as the appropriate unit of analysis to address the challenges facing water resources management; and modeling at this scale can provide essential information for policymakers in their resource allocation decisions. This paper introduces an integrated economic-hydrologic modeling framework that accounts for the interactions between water allocation, farmer input choice, agricultural productivity, nonagricultural water demand, and resource degradation in order to estimate the social and economic gains from improvement in the allocation and efficiency of water use. The model is applied to the Maipo River Basin in Chile. Economic benefits to water use are evaluated for... |
