Labor requirements and profitability of alternative soil fertility replenishment technologies in Zambia AgEcon
Ajayi, Olu Clifford; Akinnifesi, Festus K..
Low soil fertility is a major concern in agricultural productivity and development policy discourse in sub-saharan Africa. The problem is exacerbated by government withdrawal from fertilizer input markets and the inability of private sector operators to fill the gap. This warranted a search for other nutrient sources to supplement chemical fertilizers. Based on field data collected in Zambia, this study assessed the labor inputs implications of “improved tree fallows”, continuous maize cropping with and without mineral fertilizer and, evaluated the financial profitability of the different land use systems. Results show that agroforestry-based land use systems are more profitable (NPV between $233 and $309 per ha) than farmers’ practice of continuous maize...

Labour inputs and financial profitability of conventional and agroforestry-based soil fertility management practices in Zambia AgEcon
Ajayi, Olu Clifford; Akinnifesi, Festus K.; Sileshi, G.; Kanjipite, W..
Several agro-ecological practices have been developed to increase the range of soil fertility management options available to farmers, but little information is available on their labour input requirement and profitability relative to conventional practices. This study used a multiple visit cost-route method to estimate labour inputs and financial profitability of agroforestry-based and conventional (with and without fertiliser) soil fertility management practices in eastern Zambia. Results show that aggregated over a five-year cycle, labour inputs used under agroforestry practices were lower than fertilised maize fields but higher than non-fertilised continuous cropped maize. Agroforestry practices were more profitable (NPV ranging between $233 and $327...

The Role of Food from Natural Resources in Reducing Vulnerability to Poverty: A Case Study from Zimbabwe AgEcon
Mithofer, Dagmar; Waibel, Hermann; Akinnifesi, Festus K..
Vulnerability to poverty is a major problem in the rural areas of Sub Saharan Africa. Rural Households are confronted with various covariate and idiosyncratic shocks and are often severely constrained in coping with such events. They frequently resort to food from natural resources such as indigenous fruits during times of crisis. The availability of such food sources is increasingly at risk due to deforestation and biodiversity loss. The objective of this paper is to quantify the contribution of indigenous fruit trees towards reducing vulnerability to food insecurity and poverty. The methodology used is a multi-period stochastic household income model. The data were collected in a case study in Zimbabwe using detailed monthly income and expenditure...
