Regreening Africa: A bottom-up transformation of degraded lands

Reports & Research
Novembro, 2020
África

It is estimated that 20% of global land is either degraded or undergoing degradation, leading to an annual loss of 12 million hectares of productive land (UNCCD 2017). In Africa, some 715 million ha are degraded, including 65% of all arable land, 30% of all grazing land and 20% of all forests. This is due to increasing populations, poor land management, institutional challenges and climate change (Gnacadja and Wiese 2016).

Established in 1994, the United Nations Convention to Combat Desertification (UNCCD) is the sole legally binding international agreement linking environment and development to sustainable land management. The Convention addresses specifically the arid, semi-arid and dry sub-humid areas, known as the drylands, where some of the most vulnerable ecosystems and peoples can be found.

Successive surveys related to land degradation in India, reveal that despite several announcements and policy changes, the desertification and degradation of land and forest continues to rise. It has posed serious threats to environment, biodiversity, local economy and food security. Globally and nationally, India has been very vocal to address this issue.

In September 2015, the global community agreed on “The 2030 Agenda for Sustainable Development”, including 17 Sustainable Development Goals (SDG) and 169 targets. Goal 15 urges countries to “protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss”.

Unraveling Misunderstandings about Desertification: The Paradoxical Case of the Tabernas-Sorbas Basin in Southeast Spain

From its origins, the concept of desertification has been controversial. The prevailing confusion between two desertification visions, one that considers it as the expansion of deserts and another that emphasizes its anthropogenic component, has been transferred to society.

Desertification is defined as land degradation occurring in the global drylands. It is one of the global problems targeted under the Sustainable Development Goals (SDG 15). The aim of this article is to review the history of desertification and to evaluate the scientific evidence for desertification spread and severity. First quantitative estimates of the global extent and severity of desertification were dramatic and resulted in the establishment of the UN Convention to Combat Desertification (UNCCD) in 1994. UNCCD’s task is to mitigate the negative impacts of desertification in drylands.

Reducing Vulnerability to Desertification by Using the Spatial Measures in a Degraded Area in Thailand

Peer-reviewed publication
Fevereiro, 2020
Thailand

The process of desertification is complex, involving interaction between many factors, both environmental and anthropogenic. However, human activities, especially from land-use change and inappropriate land use, are the most influential factors associated with the desertification risk. This study was conducted in Huay Sai, a degraded land in Thailand. The Environmentally Sensitive Area Index (ESAI) model incorporating Geogracphic Information System (GIS) was applied to investigate and map the desertification sensitivity area.

Orientations stratégiques de la France à l’international pour lutter contre la dégradation des terres et la désertification (2020-2030)

La désertification est une dégradation progressive des sols dans les zones sèches, affectant leur potentiel de productivité biologique et économique. Aujourd’hui, plus de 3,2 milliards de personnes dans le monde vivent sur environ 2 milliards d’hectares de terres dégradées. Par ailleurs, 500 millions de personnes habitent dans des zones déjà touchées par la désertification. Ce phénomène, s’amplifiant et touchant aujourd’hui tous les continents, représente un réel danger pour la santé humaine, la biodiversité, le climat, la sécurité alimentaire, la stabilité et la sécurité.

Desertification Risk and Rural Development in Southern Europe: Permanent Assessment and Implications for Sustainable Land Management and Mitigation Policies

Peer-reviewed publication

Global

The United Nations Convention to Combat Desertification defines ‘land degradation’ as a reduction or loss of the biological and economic productivity resulting from land-use mismanagement, or a combination of processes, such as soil erosion, deterioration of soil properties, and loss of natural vegetation and biodiversity. Land degradation is hence an interactive process involving multiple factors, among which climate, land-use, economic dynamics and socio-demographic forces play a key role.

The latest IPCC report highlights that a change in diets for richer nations, and smarter land use, could ensure food security and mitigation of potential climate impacts.

Land surface processes — agriculture, forestry and other land use — account for 28% of anthropogenic emissions. However, natural land processes absorb about a third of the emissions from fossil fuel burning and energy production.

Sustainable rangeland management in Sub-Saharan Africa - Guidelines to good practice

Journal Articles & Books

Global

In Sub-Saharan Africa, the popular perception of rangelands and their management is that these vast areas have major problems without solutions: the common narrative focuses on overgrazing, herds of undernourished livestock, erosion and desertification, drought, famine, and conflict.

However, evidence compiled and analysed in this book show that such a view of rangelands – as being unproductive and mismanaged systems – does not reflect reality. It needs reconsideration and revision.
