The latest updates from the UNCCD e-Library

The Sahara Desert has expanded by about 10 percent since 1920, according to a new study by University of Maryland scientists. The research is the first to assess century-scale changes to the boundaries of the world's largest desert and suggests that other deserts could be expanding as well. The…
The population is estimated to reach nine billion by 2050, putting huge strains on food outputs. Combine this with climate change and desertification – leading to smaller amounts of arable land for crop production – and existing irrigation practices that over-extract groundwater and you begin to see…
Soil, a natural four‐dimensional body at the atmosphere–lithosphere interface, is organic‐carbon‐mediated realm in which solid, liquid, and gaseous phases interact at a range of scales and generate numerous ecosystem goods and services. Soil organic carbon (SOC) strongly impacts soil quality,…
Climate change can both directly and indirectly drive human migration. Despite this, strong understanding of the system of determinants of migration and their interactions, remains a knowledge gap resulting in large uncertainties and ill-informed interventions
Worsening land degradation caused by human activities is undermining the well-being of two fifths of humanity, driving species extinctions and intensifying climate change. It is also a major contributor to mass human migration and increased conflict, according to the world’s first comprehensive…
Biodiversity is vanishing at an alarming rate across most of the world, find the most comprehensive assessments of global ecosystem health to be done in decades. The five reports, published in the past week, are the culmination of three years’ work by the Intergovernmental Science-Policy Platform on…
Competition for land is increasing as demand for multiple land uses and ecosystem services rises. Food security issues, renewable energy and emerging carbon markets are creating pressures for the conversion of agricultural land to other uses such as reforestation and biofuels. At the same time,…
For over a decade, the European Capacity Building Initiative(ecbi) has adopted a two-pronged strategy to create a more level playing field for developing country in the UN Framework Convention on Climate Change (UNFCCC): training for new negotiators; and opportunities for senior negotiators from…
Plastic pollution is a globally recognized problem, with an estimated 322 million metric tons produced in 2016, excluding plastic fiber production. When evaluating the risks three main sources of microplastics (MPs) should be considered; polymer nanoparticles manufactured for specific purposes like…
Dryland areas are being seriously affected by degradation processes. The use of organic amendments in ecosystem restoration is an effective technique for accelerating soil regeneration processes in degraded drylands. This recovery is a result of the rapid increment of organic matter and clay…
Much research has been carried out on modelling soil erosion rates under different climatic and land use conditions. Although some studies have addressed the issue of reduced crop productivity due to soil erosion, few have focused on the economic loss in terms of agricultural production and gross…
Studies show that women disproportionately bear the adverse impacts of land commercialization in the global South. Investments in agribusiness, mining, or logging have resulted in loss of land and displacement of local communities, loss of livelihoods, and loss of communal assets—and the effects are…
Healthy and productive land resources form the basis of societal livelihood systems. Entire populations are directly dependent on the ecosystem services provided by land resources for their well-being. It was estimated in 2011 that up to 25% of the world’s land and soil resources can be classified…
The new UNCCD reporting process has been launched. To accommodate the highly technical nature of the new reporting process and enhance national capacity to generate, analyze, interpret and use Earth observation data, UNCCD has developed a series of online tutorials on how to use the available…
Soil erosion severely threatens the soil resource and the sustainability of agriculture. After decades of research, this problem still persists, despite the fact that adequate technical solutions now exist for most situations. This begs the question as to why soil conservation is not more rapidly…
The Intergovernmental Technical Panel on Soils has completed the first State of the World's Soil Resources Report. Globally soil erosion was identified as the gravest threat, leading to deteriorating water quality in developed regions and to lowering of crop yields in many developing regions. We…
The protection and sustainable management of soils is a precondition for sustainable development and moreover for the survival of humankind. Degraded soils, in particular in Africa, cause famine, poverty, migration and, under certain circumstances, even wars. Although insufficient protection and…
The International Yearbook of Soil Law and Policy is a book series that discusses central questions in law and politics with regard to the protection and sustainable management of soil and land – at the international, national and regional level. Volume 2 of the International Yearbook of Soil Law…
This editorial represents a clarion call for the aeolian research community to provide increased scientific input to theIntergovernmental Panel on Climate Change (IPCC) and the United Nations Convention to Combat Desertification (UNCCD) and an in-vitation to apply for ISAR funding to organize a…
A recent article "Sampling bias in climate–conflict research" in Nature Climate Change has spurred a new chapter in the lively scholarly debate over the potential relationship between climate change and violent conflict. We agree with the article’s authors that there are several forms of sampling…
Preventing and Remediating degradation of soils in Europe through Land Care (RECARE) have collated novels, movies, maps, children's books and more - all with a 'soily' theme
The international community has, for good reason, sought to emphasize the importance of migration as a global public policy issue. With heightened awareness of the multiple implications of poorly managed migration, and with the international community focused on developing a new global compact to…
The report " Making Every Drop count" released last week by the High Level Panel on Water (HLPW) indicates that the world may face a 40% shortfall in water availability by 2030. To put it another way, the current water crisis in Cape Town, South Africa, could become reality for other cities and…
The 2018 Global Report on Food Crises provides the latest estimates of severe hunger in the world. An estimated 124 million people in 51 countries are currently facing Crisis food insecurity or worse (the equivalent of IPC/CH Phase 3 or above). Conflict and insecurity continued to be the primary…
FuturePolicy.org is an online database designed for forward-thinking policy-makers, to simplify the sharing of existing and proven policy solutions to tackle the world’s most fundamental and urgent problems. Grown from the conviction that solutions exist for the most essential challenges to humanity…
