Cocoa Intensification Scenarios and Their Predicted Impact on CO2 Emissions, Biodiversity Conservation, and Rural Livelihoods in the Guinea Rain Forest of West Africa

Autor: Jim Gockowski, Denis J. Sonwa

Publikováno v: Environmental Management. 48:307-321

The Guinean rain forest (GRF) of West Africa, identified over 20 years ago as a global biodiversity hotspot, had reduced to 113,000 km2 at the start of the new millennium which was 18% of its original area. The principal driver of this environmental

TECHNICAL EFFICIENCY AND PRODUCTIVITY POTENTIAL OF COCOA FARMERS IN WEST AFRICAN COUNTRIES

Autor: Joachim Nyemeck Binam, Jim Gockowski, Guy Blaise Nkamleu

Publikováno v: The Developing Economies. 46:242-263

This paper uses survey data to examine the technical efficiency and productivity potential of cocoa farmers in West and Central Africa. Separate stochastic frontier models are estimated for farmers in Cameroon, Ghana, Nigeria, and Cote d’Ivoire, al

GROUNDNUT, MAIZE AND CASSAVA YIELDS IN MIXED-FOOD CROP FIELDS AFTER CALLIANDRA TREE FALLOW IN SOUTHERN CAMEROON

Autor: S. Badjel-Badjel, Christian Nolte, Jim Gockowski, T. Tiki-Manga, Stefan Hauser

Publikováno v: Experimental Agriculture. 41:21-37

Shortened fallow periods lead to a decline in crop yields in traditional mixed-food crop fields in southern Cameroon. Farmers use no inputs such as fertilizers for crop production in these field types. Planted fallows with adapted tree species might

Effects of calliandra planting pattern on biomass production and nutrient accumulation in planted fallows of southern Cameroon

Autor: T. Tiki-Manga, Stephan Weise, S. Badjel-Badjel, Stefan Hauser, Christian Nolte, Jim Gockowski

Publikováno v: Forest Ecology and Management. 179:535-545

Shortening of fallow periods due to pressure on land by population growth is a common problem throughout the forest zone of West and Central Africa. Crop yields after short-term fallows with natural vegetation are often low as a consequence of low nu
