| Irrigation with saline waters is a major problem in many parts of the world. Economic questions have usually been addressed using synthesized production functions and theoretically based soil salinity relations. The purpose of this paper is to estimate functions relating crop yield and salt accumulation in the soil to initial soil salinity and water quantity and quality. Crop response functions and dynamic salt balance relations are estimated from experimental data for alfalfa and cotton. The estimated functions are then used in a dynamic programming model to determine optimal water applications for different levels of initial soil salinity and crop and water prices. |

| Groundwater resources (GW) account for nearly 30 percent of the world sustainable water supplies. Yet, this resource, which is fraught with externalities, has largely been left unregulated. The economic literature on GW is predominantly of a partial equilibrium type, taking the rest of the economy parametrically. We analyze GW regulation in a general equilibrium setting, focusing on the stabilization value of GW under natural (draught) and economic (rural-urban water transfer) shocks. A general equilibrium approach allows evaluating direct and indirect effects of GW regulation on agriculture and non-agriculture sectors and extends the scope for water policy. The analysis is applied to Morocco by extending an existing computable general equilibrium (CGE)... |

| Agricultural production in many semi-arid areas over the world is affected by poor drainage and saline conditions. Optimal agricultural management can be considerably different under these conditions than in locations where these problems do not occur. A long-run steady-state model is developed to analyse several management strategies for a farm with limited natural drainage and no access to off farm facilities. The model is applied to a representative farm in California. Under optimal management, the results suggest relatively small evaporation ponds, a reduction in water application, and little change in cropping patterns. Some drainage reuse is optimal when only variable reuse costs are considered. Returns to land and management are positive in all... |

| Cooperation among players requires a realization of economic benefits to all players and a meeting of efficiency requirements through economically driven allocations. Cooperation among political (and sometimes hostile) players may not meet these requirements. Political considerations, usually ignored in economic analyses, can hinder or even block possible arrangements. A framework is proposed that includes both economic and political considerations for evaluating transfers or trades of scarce resources. This method quantifies both the economic payoffs using n-person game theory and the political likelihood of any of the coalitions actually forming, using the PRINCE Political Accounting System. The economic-political approach is applied to a case of a... |

| This paper examines how farmers have adapted to the current range of climates across China. A cross sectional method is used to analyze irrigation choice and crop choice across 8,405 farmers in 28 provinces in China. We find that both irrigation and crop choice decisions are climate sensitive. Chinese farmers are more likely to irrigate when facing lower temperatures and less precipitation. Farmers in warmer places are more likely to choose oil crops, maize, and especially cotton and wheat, and are less likely to choose vegetables, potatoes, sugar and especially rice and soybeans. In wetter locations, farmers are more likely to choose soybeans, oil crops, sugar, vegetables, cotton and especially rice, and they are less likely to choose potato, wheat... |

| We use laboratory experiments to test three different water market institutions designed to incorporate instream flow values into the allocation. The institutions are (1) a baseline with fixed minimum flow constraints, (2) an environmental agent contributing to the cost of providing instream flows, and (3) creating an instream flow right in which an environmental agent can sell the right to reduced flows. Using a "smart" computer-coordinated market, we find that direct environmental participation in the market can achieve highly efficient and stable allocations. A particularly attractive and practical feature of the third institution is that it nests the status quo in the sense that, should the environmental agent choose not to participate in the... |

| This article describes the influence of input quality and scarcity, environmental conditions, human capital, water price, and other variables on adoption rates for modern irrigation technologies in terms of both speed and extent of application. An empirical model is developed to apply these relationships to citrus groves in Israel. Results show that modern irrigation technologies tend to be adopted sooner and to a greater extent (a) on groves located on relatively low quality land, (b) in regions with higher evaporation rates, (c) on groves planted with more sensitive rootstock, and (d) on groves grown under conditions of restricted water allotments and higher water prices. Management, human capital, and scale of operation also affect the level and speed... |

| This research uses laboratory experiments to test alternative water market institutions designed to protect third-party interests. The institutions tested include taxing mechanisms that raise revenue to compensate affected third-parties, and a free market in which third-parties actively participate. We also discuss the likely implications of a command-and-control approach in which there are fixed limits on the volume of water that may be exported from a region. The results indicate that there are some important trade-offs in selecting a policy option. Although theoretically optimal, active third-party participation in the market is likely to result in free-riding that may erode some or all of the efficiency gains, and may introduce volatility into the... |

| This paper examines the cost structure of emissions abatement through different types of Clean Development Mechanism (CDM) projects. Alternative models for abatement costs are specified and estimated using CDM project-specific data. Empirical results indicate that there exist economies of scale in emission abatement through the CDM projects, and that the marginal cost of abatement significantly varies across different types of projects. The distribution of various CDM project types corresponds to the relative attractiveness of the types, in terms of the structure of the estimated marginal cost function. Thus, empirical results suggest that the CDM market operates efficiently and sends the right signals to the investors, which further explains the shying... |

| This paper focuses on empirically assessing determinants of river basin management decentralization, which is poorly understood while growing in popularity world wide. Measuring decentralization as a shift of decision making responsibility to water users or governments at the river basin level or below, the analysis sheds light on the decentralization reform process and its success, using primary data from 83 river basins world wide. Contrary to common perception water scarcity is found to be a stimulus to reform and financially endowed or developed basins do not outperform poor an underdeveloped basins; conditions improving decentralization performance include: existence of dispute resolution mechanisms; greater financial responsibility of users; and... |

| Water policy is prone to error because of the complexity of irrigated agriculture. Agriculture is spatially dependent, it exists in the context of a nation's economy with which it must compete for resources, and water markets seldom exist. The process of collective action, as Douglas North has noted, typically involves a process that places emphasis on the direct effects of a policy outcome. The constraints of collective action tend to be such that this process is not capable of "solving" the simultaneous equations of a real economy as a decentralized market mechanism can be characterized as being able to perform. The contribution of the paper is to measure the direct and indirect effects of irrigation water policy in an economy-wide context for the case... |
