A Study about the Causes for Low Adoption Rates of Agriculture Research Results in West and Central Africa : Possible Solutions Leading to Greater Future Impacts. by CGIAR Interim Science Council, International Institute of Tropical Agriculture, Brader, Lukas

“…As a consequence the system agreed to adopt a stronger regional orientation in its research planning and implementation, and to diversify and expand its partnerships to ensure that its limited resources are effectively leveraged in addressing the problems of the poor.The study means to contribute to this new approach by looking into the following issues in relation to the West and Central African region:- the appropriateness of currently available improved technologies giventhe agro-ecological and socio-economic conditions in the region,- the efficiency of the present technology transfer mechanisms in widelyreaching the producers,- the bottlenecks (technical, institutional, organizational and cultural)that restrain the generation, dissemination and adoption of improvedtechnologies, and- implications of the above issues for the new CGIAR regionalizationstrategy, leading into recommendations towards an increased impact ofits future research efforts.This report is an annex to the Interim Science Council's report entitled "Progress Report on Regional Approach to Research".The report was discussed at the stakeholder meeting at AGM02, agenda item 7.…”

Integrated pest management: good intentions, hard realities. A review by Deguine, Jean-Philippe, Aubertot, Jean-Noël, Flor, Rica Joy, Lescourret, Françoise, Wyckhuys, Kris A.G., Ratnadass, Alain

“…We believe that despite many good intentions, hard realities need to be faced. 1) We identify the following major weaknesses: i) a multitude of IPM definitions that generate unnecessary confusion; ii) inconsistencies between IPM concepts, practice, and policies; iii) insufficient engagement of farmers in IPM technology development and frequent lack of basic understanding of its underlying ecological concepts. 2) By diverting from the fundamental IPM principles, integration of practices has proceeded along serendipitous routes, proven ineffective, and yielded unacceptable outcomes. 3) We show that in the majority of cases, chemical control still remains the basis of plant health programs. 4) Furthermore, IPM research is often lagging, tends to be misguided, and pays insufficient attention to ecology and to the ecological functioning of agroecosystems. 5) Since the 1960s, IPM rules have been twisted, its foundational concepts have degraded and its serious (farm-level) implementation has not advanced. …”

Supporting the vulnerable: Increasing adaptive capacities of agropastoralists to climate change in West and southern Africa using a transdisciplinary research approach by Steeg, Jeannette van de, Herrero, Mario, Notenbaert, An Maria Omer

“…First a generalized downscaling and data generation method was used to take the outputs of a General Circulation Models (GCM) to describe some future climatology and to allow the stochastic generation of daily weather data that are to some extent characteristic of this future climatology, that can then be used to drive impact models that require daily (or otherwise aggregated) weather data. …”
