Integrating research on food and the environment: An exit strategy from the rational fool syndrome in agricultural science
The thesis of this paper is that the "rational fool" syndrome can be applied to mainstream public sector agricultural research that is conducted in a way that is rational in the short term, but acts against its own long-term viability. Historically, a main concern of such research has been to maximize high levels of food production together with low prices to consumers. As a result, mainstream agricultural science has ignored negative impacts or externalities, which has contributed to a crisis of credibility with the general public and politically sensitive decision makers.
Intensifying production among smallholder farmers: The impact of improved climbing beans in Rwanda
While bush beans ( Phaseolus vulgaris check for this species in other resources L.) have long been the protein staple of Rwandan agriculture, improved climbing beans have been introduced within the last 10 years, enabling farmers to intensify, stabilize and better stagger production. Through a 1992-3 nation-wide survey of 1050 households, conducted in both major growing seasons, this study examines the adoption of improved climbing beans across regions and potential user groups.

Is it possible to mitigate greenhouse gas emissions in pastoral ecosystems of the tropics?
Climate change science has been discussed and synthesized by the world's best minds at unprecedented scales. Now that the Kyoto Protocol may become a reality, it is time to be realistic about the likelihood of success of mitigation activities. Pastoral lands in the tropics hold tremendous sequestration potential but also strong challenges to potential mitigation efforts. Here we present new analyses of the global distribution of pastoral systems in the tropics and the changes they will likely undergo in the next 50 years.
Is it worth to recuperate degraded pasturelands? An evaluation of profits and costs from the perspective of livestock producers and extension agents in Honduras
The objectives of this study were to: (a) estimate milk and beef yields obtained from cows grazing pastures in different stages of degradation; (b) estimate income losses as a result of the degradation process; (c) estimate the proportion of pasture areas found in each stage of degradation within the six administrative regions of Honduras; and (d) identify different strategies and costs to recuperate degraded pastures. Data came from two surveys executed during a workshop carried out in March 2004.
