Variability in woody plant species, vegetation assemblages and anthropogenic activities derails the efforts to have common approaches for estimating biomass and carbon stocks in Africa. In order to suggest management options, it is important to understand the vegetation dynamics and the major drivers governing the observed conditions. This study uses data from 29 sentinel landscapes (4640 plots) across the southern Africa. We used T-Square distance method to sample trees.

Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

Volume 8 Issue 7
Publication évaluée par des pairsjuillet, 2019Botswana, Zambie, Mali, République-Unie de Tanzanie, Cameroun, AfriqueRecent debates in social anthropology on land acquisitions highlight the need to go further back in history in order to analyse their impacts on local livelihoods. The debate over the commons in economic and ecological anthropology helps us understand some of today’s dynamics by looking at precolonial common property institutions and the way they were transformed by Western colonization to state property and then, later in the age of neoliberalism, to privatization and open access.

The promotion of land, soil and water conservation measures has been a widespread development in sub-Saharan Africa in a bid to tackle degradation and improve productivity. As a result, several governments have launched various campaigns on soil, land and water conservation measures. The aim of this study is to determine some of the factors that influence farmers’ awareness (knowledge) and adoption of land, soil and water conservation practices. Data for this study was collected from 312 households using a questionnaire survey in the Chinyanja Triangle of Southern Africa.

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. We used two Landsat 8 Enhanced Thematic Mapper (TM) images taken in March 24th and July 14th, 2014 (path 175, row 71) to calculate water level and vegetation type which are the two main criteria used by Lozi People for differentiating eco-types.

This case study draws on research that investigated the financial sustainability of cities in the Southern African region. The research was undertaken by the South African Cities Network (SACN). The project was jointly sponsored by the Public Private Infrastructure Advisory Facility and the World Bank. The contribution by SACN of the material for this document is gratefully acknowledged. The learning material presents an outline of the many challenges of financial sustainability and effective service delivery facing Southern African cities.

Geospatial datasets and analysis techniques based on geographic information systems (GIS) have become indispensable tools in the planning, implementation and evaluation of a wide range of development programmes, including actions addressing sustainable agriculture and rural development. The growing volume of spatially explicit environmental information, combined with the widening utilization of GIS, allows ecological and socioeconomic factors to be integrated more fully into the decision-making process, thus laying the foundation for a holistic approach to development.
