Previous studies of deforestation have focused on agriculture, population and migration, timber exploitation, macroeconomic policies and geographic factors to explain the variability of deforestation rates among countries. This study tests the hypothesis that countries with a high proportion of p...

Forest-based farmers are faced with rapidly changing economic opportunities due to many factors. In response, farmers are changing their main economic activities and land uses. This study compares the financial costs and benefits of the principal land use options in two sub-districts of East Kali...

This paper aims at analyzing fuel consumption in households of forest zones, and at showing the place of fuelwood as a source of energy in the region. The study was carried out in Cameroon and it was based on a survey done in 1996. A sample of 400 households from Yaounde, Mbalmayo and Ebolowa was...

Agricultural intensification of farming systems in sub-Saharan Africa is a prerequisite to alleviate rural poverty and improve livelihoods. Legumes have shown great potential to enhance system productivity. On-farm experiments were conducted in different agro-ecological zones (AEZ) in Western Ken...

Trypanosomiasis, a disease transmitted by the tsetse fly, is a major constraint to livestock production and mixed farming in Africa. This study examines the economics of the village production of trypanotolerant cattle recently introduced in an affected area of Togo that was previously virtually ...


Itty, P.Rowlands, G.J.Morkramer, G.Defly, A.D'Ieteren, G.D.M.[The economics of recently introduced village cattle production in a tsetse affected area. (II): Trypanotolerant cattle in southern Togo]The economics of recently introduced village cattle production in a tsetse affected area. (II): Trypanotolerant cattle in southern Togo

A whole farm simulation approach was used to assess the economic impacts of five alternative strategies for controlling East Coast fever (ECF), a cattle disease, on farms from two sites in Kenya. The strategies were also ranked using the stochastic dominance criterion to determine the most prefer...


Nyangito, H.O.Richardson, J.W.Mukhebi, A.W.Zimmel, P.Namken, J.Perry, Brian D.[Whole farm simulation analysis of economic impacts of East Coast fever immunization strategies on mixed crop-livestock farms in Kenya]Whole farm simulation analysis of economic impacts of East Coast fever immunization strategies on mixed crop-livestock farms in Kenya

Presents results of economic analysis carried out in southwestern Nigeria to determine the profitability of alternative land use systems, taking into account the short and long-run impact of soil erosion on agricultural productivity. The fallow systems include 1. two continuous cultivation alley ...

Describes the production and herd characteristics of Zebu cattle in Arusha, northern Tanzania. Uses the production and herd structure parameters in a simulation of herd growth, under various rates of mortality, production and offtake.


Ngategize, P.K.[Economic evaluation of improved management for Zebu cattle in northern Tanzania]Economic evaluation of improved management for Zebu cattle in northern Tanzania

Evaluates alley farming models with small ruminants based on field and experimental data from southwest Nigeria, and compares them to basic alley cropping and to fallow systems. Describes the basic fallow model, the basic alley cropping model without animals, the alley farming model with goats, a...

Low soil fertility is a fundamental constraint to crop production in western Kenya. Although researchers have developed many soil fertility-improving technologies, the adoption of these technologies is low due to inadequate awareness of the technologies, poor access to requisite resources and uns...
