"This paper investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favored production environments of a developing agricultural economy.

The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country.

Extreme interannual variability of precipitation within Ethiopia is not uncommon, inducing droughts or floods and often creating serious repercussions on agricultural and non-agricultural commodities.

The paper develops a framework for the design and analysis of pluralistic agricultural advisory services and reviews research methods from different disciplines that can be used when applying the framework.

Changes in India’s seed regulations during the 1990s favored the growth of privately- as compared to publicly-funded sectors.

Compared to both Canada and the United States, Australia has been slow to approve commercial planting of transgenic crops. Two probable reasons exist for the slow approval rate of transgenic crops in Australia.

"A vast literature has accumulated since crop varieties with transgenic resistance to insects and herbicide tolerance were released to farmers in 1996 and 1997.

" Hungarian home gardens are small-scale farms managed by farm households using traditional management practices and family labor.

The paper discusses the application of the Water Poverty Index (WPI) as a monitoring tool for Benin’s water sector.

This paper reviews current trade–related regulations of genetically modified (GM) food and discusses their effects on developing countries. There is a large heterogeneity in current import approval and marketing policies of GM food worldwide.

This paper analyzes the current and proposed biosafety systems in Kenya, Tanzania, and Uganda using a set of components and characteristics common to functional and protective biosafety regulatory systems.

The regulatory approval of genetically modified crops in the field initially requires small, restricted experimental trials known as confined field trials.

Les réglementations relatives à l’approbation de cultures génétiquement modifiées exigent, initialement, des petites expérimentations restreintes appelées essais au champ confinés.

This study examines farmers’ preferences for seed of new rice varieties and their willingness to pay for seed-related information in villages of Nigeria and Benin.

A lack of data often makes biological management decisions difficult and has been an area of contention in the debate over the approval of transgenic crops.

Pollution of the environment by metals and organic contaminants is an intractable global problem, with cleanup costs running into billions of dollars using current engineering technologies.

Phytoremediation is the use of living plants, known as hyperaccumulators which absorb unusually large amounts of metals in comparison to other plants.

We examine access to, use of, and participation in decisions on improved water supply in the Volta basin of Ghana, one of the first countries to introduce a community-based approach to rural water supply on a large scale.
