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.

What’s the goal here? To sustainably manage forests, combat desertification, halt and reverse land degradation, and halt biodiversity loss. Two billion hectares of land on Earth are degraded, affecting some 3.2 billion people, driving species to extinction and intensifying climate change. Goal 15: Life on land Human life depends on the earth as much as the ocean for our sustenance and livelihoods. Plant life provides 80 percent of the human diet, and we rely on agriculture as an important economic resources.

Facts and Figures: ➡ Every minute, 23 hectares of arable land are lost due to drought and desertification. ➡ Over the last two decades, approximately 20 per cent of the Earth’s vegetated surface has shown persistent declining trends in productivity, mainly due to unsustainable land and water use and management practices. ➡ Every year, 13 million hectares of forest are lost that are home to more than 80 per cent of all land-based species and which provide livelihood to 1.6 billion people.

Meeting the Sustainable Development Goals requires drylands sustainability. Treating drylands as global environmental commons enables better tailored governance responses. Key nested governance elements for drylands involve setting goals, monitoring and delivering sanctions across scales. The present global governance system for drylands only partially delivers these elements. Drylands require a particular focus on linking local and global governance.

In the past decades, debates on agriculture, land use and management of natural resources have coined a wealth of new terms. In many cases, these are in full vogue for just a period, replace older ones or are used for political reasons. Meanwhile, there are so many terms that it is difficult to keep track and distinguish them from each other.

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. Meanwhile, recent assessments remind us that two billion hectares of land are now degraded worldwide. This represents an area larger than the territory of the Russian Federation, the biggest country in the world.

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.

Two billion hectares of productive land are degraded worldwide. This is an area larger than South America or twice the size of China, and 500 million hectares of this is abandoned agricultural land. We continue to degrade another 12 million hectares of productive land every year. We need to break this destructive cycle because the benefits of preventing land degradation and reversing it are far greater than the gains from degrading new land year after year.

The remit of this paper is to identify and examine “success” stories in combating desertification.

The Intergovernmental Panel on Climate Change (IPCC) published its Climate Change and Land: An IPCC Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems in 2019 (www.ipcc.ch/srccl). We refer to the IPCC’s report in short here as the Special Report on Climate Change and Land. The Special Report was a response to proposals from governments and observer organisations to the IPCC.

Vast swathes of land, from Africa to the Middle East, are being left useless by climate shifts and human pressures such as deforestation, mining and farming, threatening to hike migration and conflict. The accelerating damage could cost the global economy a staggering $23 trillion by 2050 - and rich countries as well as poor will pay the price.

Interview with Ibrahim Thiaw

Land provides crucial ecosystem services for human existence and human well-being, including provisioning, regulating, supporting and cultural services. Those services provide among others the production of fresh air, food, feed, fuel and fibre. They regulate the risks of natural hazards and climate change, offer cultural and spiritual values to our society, and support key ecological functions such as nutrient and water cycling, filtering and buffering, and are central to economic vitality.
