摘要

A detailed agro-ecosystem characterization was carried out in the Kpene catchment of the Jolo-Kwaha watershed in Northern Ghana at a scale of 1:5000. The objective was to examine the environmental and socio-economic characteristics of the Kpene area and identify the constraints on sustainable agricultural production, especially soil and water management. Environmental data, particularly land use and soil types were obtained through transect surveys while socio-economic data through participatory rural appraisal (PRA) techniques. The area falls within the Guinea Savanna agro-ecological zone of Ghana with a unimodal rainfall regime. With a Land Use Ratio (LUR) of almost 100%, land use is very intense and fallow is almost non-existent the fanning system. The uplands have mainly deep, well - drained and non-concretionary Lixisols, and the lowlands, deep and imperfectly to poorly drained Planosols and Gleysols. The Kpene community has an average of 40 persons per household, with majority (45%) being between 15-45 years of age. The major occupation is farming with land ownership being entirely through inheritance. Major crops grown are maize, yam, rice and groundnuts. In soil fertility management, 70% apply mineral fertilisers, especially to rice. Some constraints on agricultural production are erratic and unreliable rainfall, low soil fertility and poor water management. Levelling for proper water conservation in the valley bottoms and water harvesting can enhance agricultural production.
