Soil erosion is a global environmental problem and a pervasive form of land degradation that threatens land productivity and food and water security. Some of the biggest sources of sediment in catchments are cultivated and abandoned lands. However, the abandonment of cultivated fields is not well-researched. Our study assesses the level of degradation in cultivated and abandoned lands using a case study in South Africa. We answer three main questions: (1) What is the extent of crop field degradation on used, partly used, and abandoned fields?

From 24 to 26 November 2020, the three organisations comprising the Life After Coal campaign, Earthlife Africa (Johannesburg), the Centre for Environmental Rights and ground Work, met virtually to develop a shared Open Agenda on the Just Transition. We used the Open Agenda for a Just Transition - developed at the National Coal Exchange in Middelburg, Mpumalanga, in July 2019 - as a starting point.

According to South African government records, there are no fewer than 400 abandoned coal mines.The risks from unrehabilitated mines extend far beyond the people who access the sites –they risk polluting the water of millions of South Africans. Coal across South Africa is found predominantly in ores with sulfur-bearing minerals. When these ores come into contact with water and air, sulfuric acid is created, which can lead to further leaching of heavymetals from ores. This reaction poses significant risks to water and agricultural land in many parts of South Africa, including in Mpumalanga.

Agricultural activities are directly dependent on the availability and quality of natural resources, particularly land and water. While the availability of land has featured strongly in South Africa’s growth and transformation policy agendas, this piece focusses on presenting a more detailed view of the quantity and quality of South Africa’s land resource, and how this impacts the agricultural use and viability of land resources in sustaining South Africa growth objectives.

This is the PDF version of an online data story published by Land Portal on 28 April 2022.
Colonial and apartheid land dispossession in South Africa was the most extensive of any country in sub-saharan Africa. Despite a land reform programme initiated after the transition to democracy in 1994, equitable access to land remains an unresolved question in both urban and rural areas.

Nature-based solutions (NbS) include all the landscape’s ecological components that have a function in the natural or urban ecosystem. Memorial Parking Trees (MPTs) are a new variant of a nature-based solution composed of a bioswale and a street tree allocated in the road, occupying a space that is sub-utilised by parked cars. This infill green practice can maximise the use of street trees in secondary streets and have multiple benefits in our communities. Using GIS mapping and methodology can support implementation in vulnerable neighbourhoods.

As of 2017, SGP has awarded over 3,800 small grants to land degradation projects in over 120 countries, many of which are in regions with extreme levels of poverty and food insecurity across Africa and Latin America. Africa, in particular, is experiencing the highest population growth of the developing world, while being exposed and vulnerable to the rising impact from climate change.

Dryland mountains are among the least-known environments in the world, and certainly one of the most overlooked by decision- and policy-makers. Dryland mountains have an outstanding strategic value. They act as water towers for surrounding dry lowland areas, as shown by the examples of the Rocky Mountains of North America, the Central Andes, the mountains of the Mediterranean Basin, the Sahara and Sub-Saharan Africa, West Asia, and Central Asia

Today, the Coalition for Urban Transitions releases a new report ‘Seizing the Urban Opportunity’, which provides insights from six emerging economies on how national governments can recover from COVID-19, tackle the climate crisis and secure shared prosperity through cities. Launching as a call to action for national governments ahead of COP26 in Glasgow, it builds on the Coalition’s flagship 2019 report: Climate Emergency, Urban Opportunity.
