With current rates of land degradation reaching ten to twelve million ha per year, there is an urgent need to scale up and out successful, profitable and resource-efficient sustainable land management practices to maintain the health and resilience of the land that humans depend on. As much as 500 million out of two billion ha of degraded land, mainly in developing countries, have restoration potential, offering an immediate target for restoration and rehabilitation initiatives.1 In the past, piecemeal approaches to achieving sustainable land management have had limited impact.

Although advances in remote sensing have enhanced mapping and monitoring of irrigated areas, producing accurate cropping information through satellite image classification remains elusive due to the complexity of landscapes, changes in reflectance of different land-covers, the remote sensing data selected, and image processing methods used, among others. This study extracted agricultural fields in the former homelands of Venda and Gazankulu in Limpopo Province, South Africa.

In recent decades, many countries in sub-Saharan Africa have pursued national water permit systems, derived from the colonial era and reinforced by “global best practice.” These systems have proved logistically impossible to manage and have worsened inequality in water access. A new study conducted by the International Water Management Institute (IWMI) and Pegasys Institute, with support from the UK government, traces the origins of these systems, and describes their implementation and consequences for rural smallholders in five countries – Kenya, Malawi, South Africa, Uganda and Zimbabwe.

A survey of 76 public smallholder irrigation schemes in the Limpopo Province was jointly conducted by the International Water Management Institute (IWMI), Department of Agriculture, Forestry and Fisheries (DAFF), South Africa, and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the ‘Revitalization of Smallholder Irrigation in South Africa’ project.

This report summarizes the findings of a collaborative effort to map and assess irrigated areas in the Limpopo Province, South Africa. The study was conducted by the International Water Management Institute (IWMI) in collaboration with the Department of Agriculture, Forestry and Fisheries (DAFF) and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the DAFF-supported ‘Revitalization of irrigation in South Africa’ project.

Recent developments in Environmental Flow (E-flow) frameworks advocate holistic, regional scale, probabilistic E-flow assessments that consider flow and non-flow drivers of change in socio-ecological context as best practice. Regional Scale ecological risk assessments of multiple sources, stressors and diverse ecosystems that address multiple social and ecological endpoints, have been undertaken internationally at different spatial scales using the relative-risk model since the mid 1990's.

This report is a synthesis of research implemented for the project on Wetlands-based livelihoods in the Limpopo basin: balancing social welfare and environmental security. The research was motivated by the dependency of many people on wetlands for their livelihoods. It was therefore founded on the basis that the potential of wetlands to contribute to livelihoods is closely related to their ability to maintain ecosytem functions (such as regulating river flows), which is a consequence of their unique hydrological characteristics.

Despite challenges in many river
basins, overall the planet has
enough water to meet the full range
of peoples’ and ecosystems’ needs
for the foreseeable future, but
equity will only be achieved through
judicious and creative management.
