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.
We measure the eco-efficiency (EE) of agricultural production in regard to soil erosion and decompose it into technical efficiency (TE) and soil conservation efficiency (SCE).
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.
The Sustainable Development Goals (SDGs) adopted by the United Nations General Assembly in September 2015 include a target on land degradation neutrality (LDN) (SDG 15.3). Attaining and maintaining LDN requires addressing a land governance challenge to steer land management towards avoiding, reducing and reversing land degradation.
When the UN Convention to Combat Desertification was created at the Rio Earth Summit over 25 years ago, it became the only international convention dedicated to protecting, managing and restoring our land. The environmental benefits of that work are already well documented, particularly when it comes to the inextricablelinks with climate change and biodiversity.
A new Model Land Use Bill is proposed to address the lapses identified in the Nigerian Land Use Act (LUA, 1978), such as poor administrative system for lands, ownership, and the absence of community participation. This policy brief promotes a new land management structure for ease of business, to improve social and environmental protection, and to reduce land-grabbing by dispossession.
A call to action: 20 interventions that will matter. The report’s Call to Action identifies 20 points where interventions can create transformative and accelerated progress towards multiple goals and targets in the coming decade.
Land restoration has tremendous potential to help the world limit climate change and achieve its aims for sustainable development. In its latest study, the International Resource Panel finds positive spin-offs to support all 17 Sustainable Development Goals agreed to by the world’s nations as part of the 2030 Agenda for Sustainable Development.
The UNCCD-SPI technical report “Realising the Carbon Benefits of Sustainable Land Management Practices: Guidelines for Estimation of Soil Organic Carbon in the Context of Land Degradation” provides decision guidance for the estimation of soil organic carbon (SOC) in support of appropriate deployment of sustainable land management (SLM) technologies, in order to maintain or increase carbon in th
The 2019 edition of the Land for Life Award puts the spotlight on individuals and organizations that made outstanding contributions to achieve land degradation neutrality on a large scale, with long-term changes and dedicated actions for 25 years or longer. Those remarkable projects involve local people, communities and the society, raising the level of their ambition.
