Soil fertility decline is a major constraint to crop productivity on smallholder farms in Africa. The objective of this study was to evaluate the long-term (up to nine years) impacts of nutrient management strategies and their local feasibility on crop productivity, soil fertility status and…
The dominant modes of vegetation variability over Zimbabwe are investigated using principal component analysis (PCA) on National Oceanic and Atmospheric Administration Advanced Very High Resolution Radiometer (NOAA-AVHRR) normalized difference vegetation index (NDVI) monthly imagery from 1982 to…
Adequate operation and maintenance (O&M) of irrigation infrastructure sustains irrigation scheme facilities, reduces repair costs, helps the system last longer, and keeps irrigation efficiency at design levels. In cases where farmers do not have sufficient capacity to operate and…
The knowledge of runoff discharged by a catchment at its outlet is important for water accounting and water allocation to competing uses. Runoff generated by a catchment is important in determining the catchment water balance, estimating pollutant loads, and quantifying sediment yield and…
An evaluation of available opportunities to revive irrigation on a long abandoned irrigation scheme in a dry region of Zimbabwe is presented by assessing water availability at catchment level. The aim is to enhance the livelihoods, income and nutrition of the communities that depend on the…
The constitution was drafted by a Parliamentary Select Committee and approved by Parliament before being signed by President Mugabe.
This paper presents a methodological framework for revitalising small-scale irrigation schemes which are no longer performing well due to a combination of infrastructural, social-economic, institutional and governance problems, among others. The framework was developed as part of a project to…
Agriculture is one of the biggest sources of greenhouse gases. Rice production has been identified as one of the major sources of greenhouse gases, especially methane. However, data on the contributions of rice towards greenhouse gas emissions in tropical Africa are limited. In Zimbabwe, as in…
Water has a low profile in Comprehensive Africa Agriculture Development Programme (CAADP) processes in the Southern African Development Community (SADC), presenting an opportunity to develop stronger ties between the agriculture and water sectors in the region.
