Soil organic carbon (SOC) is a major attribute of soil quality that responds to land management activities which is also important in the regulation of global carbon (C) cycling. This study evaluated bulk soil C and nitrogen (N) contents and C and N dynamics in three soil organic matter (SOM) fractions separated by density.

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 revitalise small-scale irrigation schemes in Masvingo Province in Zimbabwe.

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.

Twenty-seven nations are classified as ‘water scarce’, a further 16 as ‘water stressed’. This situation, coupled with the fact that many surface and groundwater systems are shared between two or more states, has led governments to develop sustainable water management strategies.
