The study is focused on the development and the application of a stochastic economic optimisation model by which optimal levels of applied water and sprinkler spacing are determined. Data on crop-water production function and uniformity of water application are taken from a sprinkler irrigation...

A theory of settlement planning focussing on village-level production services is presented, and settlement plans are compared. The analysis draws on the modern theory of local public goods. Conditions for optimal level of services and optimum settlement size are derived, together with rules of...

The impact of uncertain salt balances in irrigate fields is assessed with a hydroeconomic model that incorporates the effects of salinity. Uncertainty in two parameters that jointly determine root zone salinity is investigated and the conclusions prove to depend upon the way in which these...

In order to stimulate organic farming governments generally use a mix of temporary hectare payments and provision of public services for stimulating the development of the organic sector. In this paper a conceptual model is developed for determining a socially optimal hectare payment for any...

Environmental and health risk concerns associated with the use of agricultural chemicals in the United States are increasing. In response, public policies designed to alter farming practices and the use of agricultural chemicals are being proposed and implemented. In addition, agricultural price...

With some agri-environmental restrictions, municipal wastewater can be utilized for agricultural irrigation and river rehabilitation. This paper develops a single-year planning model for a region in Israel which consists of a city and three potential wastewater consumers. The model incorporates,...

This paper investigates the effects of first-best policies to regulate nitrogen application. Some nitrogen fertilizer is applied ex ante before a random rainfall, but sidedressed nitrogen may be applied ex post. First-best policy is a tax or a quota on ex ante application, because sidedressed...

The study investigates the value of additional information on the response function to soil salinity of a given crop (potatoes), with regard to a stochastic long-run optimization model for utilization of saline water to a single farm framework. The analysis provides a conceptual and...

The economic implications of plant density for irrigation water use under saline conditions are investigated, utilizing the involved physical and biological relationships. The analysis considers a single crop and is applied to cotton data. The results suggest that treating plant density as an...
