Seasonal cycles and persistence in an acarine predator-prey system on cassava in Africa por Hanna, R., Onzo, A., Lingeman, R., Yaninek, John S., Sabelis, M.W.

“…We applied time series analysis and a mechanistic predator-prey model to long-term data of monthly population counts of the herbivorous pest mite Mononychellus tanajoa and its introduced phytoseiid predator Typhlodromalus aripo from a cassava field in Benin, West Africa. In this approach, we determined the extent to which the main features of the observed predator-prey fluctuations in cassava fields can be explained from biotic traits inherent to the biology of predator and prey, and the extent of the significance of abiotic factors in determining population levels. …”

CTA Project Completion Report: Capitalizing on experiences for greater impact in rural development por Chavez-Tafur, Jorge

“…Following the structure and the list of activities outlined in the project proposal, during these 3 years the project • helped complete the FAO/IMARK learning module on experience capitalisation and supported the production of the Spanish and French versions; • built and maintained a thematic website, and completed it with an online repository with guidebooks and manuals as well as with the results of different capitalisation processes; • prepared, used and shared a series of training materials, together with a facilitators’ guidebook – building on the resources already available, but more specifically on the experience accumulated by the project; • ran a series of training workshops and supported the completion of experience-capitalisation processes in East Africa, Mozambique, India, West Africa (in French and in English), South East Asia, the Pacific region and Latin America; • completed the editing, layout and publication of 10 booklets with the results of the capitalisation processes started in different parts of the world (with more than 120 cases in total), together with two additional booklets focusing on the capitalisation process itself and on its institutionalization; • worked together with other organisations, such Farm Radio International and the International Land Coalition, in the analysis and documentation of their projects’ activities; • ran a series of webinars for online facilitators, focusing on the organisation and facilitation of a community of practice, and invited different participants to guide and facilitate the regional communities - in English (East and West Africa and in the Pacific region), French (West Africa), Portuguese (Brazil and Mozambique) and Spanish (Latin America); • presented the results achieved in international conferences and seminars (in Benin, Mauritania and the Netherlands); and • helped prepare a series of capitalisation processes within CTA, as part of a thorough analysis of its different intervention areas.…”
