Cel African farmers operate under the deleterious effects of a rapidly degrading resource base, particularly from nutrient depletion and soil erosion. Soil organic matter plays a key role in crop sustainability primarily through its interactions with soil chemical and physical properties in relation to nutrient release, cation retention and maintenance of soil structure. By improved management of organic resources, soil erosion is reduced, soil fertility is more sustainable, farm productivity is increased and the quality of life of farmers is enhanced. The principal objective of this proposal is to develop and test an innovative methodology for modification and improvement of the indigenous soil fertility management practices of smallholder farmers in four countries in East and Southern Africa, by increasing the efficiency of use of organic and inorganic resources. Simultaneously, the project aims to enhance the capability of research institutions in these four countries to conduct farmer participatory research in resource management. The research approach involves three phases, which will be conducted in case-study sites in each of the four countries: Kenya, Tanzania, zambia, and zimbabwe. In the first phase, a multi-disciplinary team of social, soil, and biological scientists will work with farmers to identify research priorities, formulate hypotheses, and characterise available resources for their potential in alleviating the primary constraints limiting productivity in key components of the agroecosystems. In the second phase, soil biological process studies will be conducted on-station and on-farm to test strategies for modifications to indigenous soil fertilitv management practices to improve resource use efficiency. In the third phase, spatial models will be constructed in order to determine the applicability of extrapolation of improved management practices to wider areas. The project builds on the experimental approach, methodologies and African research network of the Tropical Soil Biology and Fertility programme Dziedzina nauki social sciencessociologydemographyfertilitysocial scienceseconomics and businesseconomicsproduction economicsproductivityagricultural sciencesagriculture, forestry, and fisheriesagriculturesocial scienceseconomics and businessbusiness and management Program(-y) FP3-STD 3 - Specific research and technological development programme (EEC) in the field of the life sciences and technologies for developing countries, 1990-1994 Temat(-y) Data not available Zaproszenie do składania wniosków Data not available System finansowania CSC - Cost-sharing contracts Koordynator BBSRC Institute of Arable Crops Research Wkład UE Brak danych Adres Rothamsted Experimental Station AL5 2JQ Harpenden Zjednoczone Królestwo Zobacz na mapie Koszt całkowity Brak danych Uczestnicy (7) Sortuj alfabetycznie Sortuj według wkładu UE Rozwiń wszystko Zwiń wszystko Institut Français de Recherche Scientifique pour le Développement en Coopération (ORSTOM) Francja Wkład UE Brak danych Adres 70-74 route d'Aulnay 93143 Bondy Zobacz na mapie Koszt całkowity Brak danych Kenya Agricultural Research Institute Kenia Wkład UE Brak danych Adres Nairobi Zobacz na mapie Koszt całkowity Brak danych Misamfu Research Station Zambia Wkład UE Brak danych Adres Kasama Zobacz na mapie Koszt całkowity Brak danych Sokoine University of Agriculture Tanzania Wkład UE Brak danych Adres Morogoro Zobacz na mapie Koszt całkowity Brak danych UNIVERSIDAD COMPLUTENSE DE MADRID Hiszpania Wkład UE Brak danych Adres Isaac Peral 28040 MADRID Zobacz na mapie Koszt całkowity Brak danych UNIVERSITY OF COPENHAGEN Dania Wkład UE Brak danych Adres 83,Solvgade 83 H 1307 KOEBENHAVN K/COPENHAEGEN Zobacz na mapie Koszt całkowity Brak danych University of Zimbabwe Zimbabwe Wkład UE Brak danych Adres MP 167 Harare Zobacz na mapie Koszt całkowity Brak danych
