This study illustrates a methodology to measure empirically household food vulnerability. Food vulnerability is defined in terms of the probability now of being undernourished in the future. The empirical analysis is based on panel data from northern Mali, collected in 1997-98. Our empirical results clearly show that even though the groups of currently(More)

The CSW RTP program, which adopted the two-part, revenue neutral design first introduced by Niagara Mohawk, was introduced(More)

We developed a deterministic, multi-period linear programming (LP) model of the dual-purpose (milk-beef) cattle production system in the Sur del Lago region of Venezuela. The LP model selected animal, forage, and purchased feed activities subject to nutritional, land, and herd composition constraints to maximize discounted herd net margin. A cattle(More)
Agriculture's multifunctional role as provider of non-commodity outputs has received increased attention in the debate on the future of agricultural policy. To identify appropriate economic policies, a distinction must be made between concerns involving market failure and a consequent misallocation of resources, and those relating to distributional issues.(More)
Household food insecurity indicators are typically static in nature, thereby ignoring a key dimension of food insecurity. This paper develops an explicitly forward-looking food insecurity indicator that takes into account both current dietary inadequacy and vulnerability to dietary inadequacy in the future. Application of this measure to data from northern(More)
To achieve a given level of an environmental amenity at least cost, decision-makers must integrate information about spatially variable biophysical and economic conditions. Although the biophysical attributes that contribute to supplying an environmental amenity are often known, the way in which these attributes interact to produce the amenity is often(More)
Shifting cultivation is the primary means of livelihood for subsistence farmers throughout the humid forests of the tropics. Sustainable use of the resource base as a source of fertile land for cultivation requires long periods of fallow and the ability to move the zone of active cultivation from one location to another over time. At the individual patch or(More)
