This study is based on a panel survey interviewing 416 farmers practising conservation agriculture for at least five cropping seasons. Farmers obtained higher yields on conservation agriculture plots than on nonconservation agriculture ones. The mean maize yield on conservation agriculture was...

L'objectif de cet article est de calculer l'efficacité économique et environnementale liée à l'utilisation des eaux souterraines dans les petits périmètres irrigués de la Tunisie. L'impact environnemental pris en compte dans notre étude est le niveau d'épuisement de l'eau dans les...

Smallholder farms in the humid highlands of East Africa are undergoing changes that question the notion of the rural space. Characterized by land degradation, increasing population pressure, intensive farming and continuous cropping in small plots, smallholder farmers have increasingly embraced...

Jatropha curcas L. (or physic nut), a previously underutilized tree species in smallholder farming systems, is fast gaining formal recognition as a very important tree crop in improving rural livelihoods. The Government of Zimbabwe is vigorously promoting the growing of Jatropha in marginal...

Recent studies on the economics of agricultural water management in Tunisia report a low water productivity of some presently widely cultivated crops such as durum wheat. The objective of this study is to estimate water productivity and marginal value of irrigation water applied to durum wheat...

The main objective of this study was to understand the rural energy consumption of the farming households. The data used for the study were obtained through a four-stage sampling procedure which resulted in a sample size of 120 households. Logistic regression procedure was used to determine the...

Preserving, managing and improving the health of forest ecosystems worldwide will require equitable leadership and participation from both women and men. Understanding gendered motivations to conserve forest ecosystems may contribute to the design of programs that enable sustainable management...

This study employs stochastic DEA approach for measuring irrigation water efficiency of wheat farms in irrigated areas of Chbika (Central Tunisia). Data was collected from 170 wheat farms during 2010-2011cropping season. The empirical results show that the average water use efficiency calculated...

Etant donné l’ampleur du phénomène de la salinité en Tunisie, sa prise en compte dans le calcul économique devient de plus en plus indispensable. il s’agit d’internaliser cette externalité à travers l’ajustement des coûts par la valeur économique de la dégradation. Le choix a...

The efficiency with which farmers use available resources is very important in agricultural production. This study examines the resource use efficiency of cassava-based mixed crop farmers in Ogun and Oyo States, Nigeria. Cross-sectional data were collected from 265 cassava-based farmers (150 in...
