Land reform was launched in the Republic of Georgia in 1992, about a year after the country gained its independence from the Soviet Union. While an impressive land individualization process has been in effect since then, the pace and the performance of this process are far from satisfactory....

Water management and reuse at the field level are analyzed under saline, limited drainage conditions. A function relating crop yield and deep percolation flows to applied water and salinity concentration is developed. This function fits simulated data well and is tractable for theoretical and...

This paper evaluates the effectiveness of changing land allocation among crops as a mechanism for increasing social welfare, where production profits and amenity benefits are augmented. A positive mathematical programming model is calibrated and applied to the northern part of Israel, using a...

We analyze the management of a coastal aquifer under seawater intrusion using distributed control methods. The aquifer's state is taken as the water head elevation, which varies with time and in space since extraction, natural recharge and lateral water flows vary with time and in space. The...

This article examines the decision of farmers to sell part of their farm output on the market, using data from the Republic of Georgia. A two-level empirical model is used, in which endowments and resource allocation decisions determine farm output and non-farm income, and these in turn...

This paper presents a comprehensive economic analysis of recycling organic wastes through composting. A mathematical programming model is developed to examine the optimal level of compost production from sources of organic municipal solid waste, livestock manure and wastewater-treatment sludge....

The purpose of this paper is to examine the situation of individual farms in Georgia using a survey conducted in 2003, in comparison to a similar survey conducted in 1996. The basic issue investigated is the progress of the land individualization process, and the consequences of this process for...

This article proposes a proactive approach for analyzing agricultural adaptation to climate change wherein agricultural production technologies are regarded as potential targets of research and development (R&D) efforts. We develop a structural land-use model wherein farmers maximize profit by...

We develop an empirical farmland allocation model based on explicit profit functions that is linked to a market demand model. The model accounts for corner solutions, enabling estimation with disaggregated data, and thereby allows treating prices as exogenous. The integrated model enables...

Drainwater management strategies include source control, reuse, treatment, and evaporation ponds; questions of interest are efficient management, policy instruments, and sustainability. A high level of source control is indicated absent reuse due to the relatively high cost of evaporation ponds;...
