Soybean rust is a highly mobile infectious disease and can be transmitted across short and long distances. Soybean rust is estimated to cause yield losses that can range between 1%-25%. An analysis of spatio-temporal infection risks within the United States is performed through the use of a...

Ethics and agriculture is a complex debate, but one in which agricultural economics students must be prepared to participate. There are many links between economics and ethic or moral philosophy. Classroom teaching tends to focus on discussion of issues involving behavioral ethics and disregards...

Consistency of functional characteristics in wheat is a concern confronting buyers and sellers. This research analyzes the cost and risk of different procurement strategies for importers. A stochastic simulation model is used to determine the probability of functional characteristics being...

This study examines the impact of climate change on cropland in Africa, using a Ricardian cross-sectional approach. Relying on farm data from an 11-country survey of over 9500 farmers, annual net revenue is regressed on climate and other variables. The study confirms that current climate affects...

Economic modelling of semi-arid rangelands has received much attention in recent literature. A major outstanding issue is how stochastic rainfall and the feedback effect of heavy grazing pressures on vegetation productivity can be accounted for in these models. This paper presents a model for...

This paper examines the impact of climate change on primary crops grown in Africa. An innovative approach is presented that bridges the gap between agro-economic and traditional Ricardian models. We label it a ‘structural Ricardian model’. It first captures the type of crop a farmer...

This paper examines the effect of changes in climatic averages on agricultural production at the national level in Cameroon. The empirical results reveal that Cameroon’s agriculture is influenced by climate variables. The economic value of the projected output in 2050 ranges from USD3.5...

This study uses the inverse almost ideal demand system (IAIDS) to estimate demand flexibilities for beef, small ruminant (sheep and goat) meat, pork and poultry in Tanzania. Own uncompensated price flexibilities were less than one in absolute value, implying that both direct and indirect induced...

This paper discusses the possible effects of various ways of charging for water in an integrated modeling framework adapted to the Drâa River Basin in southeastern Morocco. Declining surface water availability in the basin has led to an increase in groundwater use for irrigation in recent...

Climate change and increasing climate variability threaten the attainment of the Millennium Development Goals (MDG), and some of the worst effects on human health and agriculture will be in sub-Saharan Africa, particularly in vulnerable regions. The relationships between climate change and the...
