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.
Bush encroachment is a matter of growing concern in the semi-arid regions of Namibia. Locally adapted, long-term solutions for land restoration must be elaborated. It is crucial that local scientists are empowered to map and monitor the degradation process themselves, our authors maintain.
This eco-type map presents land units with distinct vegetation and exposure to floods (or droughts) in three villages in the Barotseland, Zambia. The knowledge and eco-types descriptions were collected from participatory mapping and focus group discussions with 77 participants from Mapungu, Lealui, and Nalitoya.

As climate change makes precipitation shocks more common, policymakers are becoming increasingly interested in protecting food systems and nutrition outcomes from the damaging effects of droughts and floods (Wheeler and von Braun, 2013).
Recent estimates show that one third of the world’s land and water resources are highly or moderately degraded. Global economic losses from land degradation (LD) are as high as USD $10.6 trillion annually.
Urban agriculture is said to be increasing with global urbanization. However, there is little examination of the temporal or spatial dynamics of urban agriculture. We investigated the benefits and challenges experienced by community gardeners in four towns in South Africa, along with GIS analysis of the number, area, and location of urban food community gardens over the last three decades.
Agriculture influences and shapes the world’s ecosystems, but not always in a positive way. More than 2.5 billion people are globally involved as stewards of land and water ecosystems that constitute the natural resource base for feeding the current and future world population.
