Land markets are evolving in response to increasing population pressure in Africa.
High population pressure leads to land use intensification on very small farms.
Population growth in densely populated rural areas leads to increasing rural–urban youth migration.
Tenure security enhancing land reforms enhance investments and sustainable land use intensification.
Pro-poor development strategies should target the strengthening of land governance.

The UNEP foresight report contains a description of the 21 emerging environmental issues identified through the UNEP Foresight Process. The process resulted in a list of 21 emerging environmental issues tagged 21 Issues for the 21st Century covering the major themes of the global environment including food, land, freshwater, marine, biodiversity, climate change, energy, waste, and technology, as well important cross-cutting issues ranging from the need for better environmental governance, to the need for human behavioral change towards the environment.

Land degradation is a pervasive, systemic phenomenon: it occurs in all parts of the terrestrial world and can take many forms. Combating land degradation and restoring degraded land is an urgent priority to protect the biodiversity and ecosystem services vital to all life on Earth and to ensure human well-being

The negative consequences of human actions have brought our world and our future to a dangerous crossroads: will we be able to avert the worst impacts of climate change? How can we stop and reverse the loss of fertile soil, biodiversity, and other natural capital that supplies all our food and other basic needs? Where are the jobs for millions of unemployed young people?

The support plan for the Sahel is a regional approach to collectively address the root causes of disruptions such as poverty, migration and youth unemployment, climate change, insecurity, governance and institutional issues in the region. In this report an overview of the current situation for each of the priority areas of the UN Support Plan is presented to demonstrate that the full implementation of the plan could utilize an existing momentum of development not seen in decades in the Sahel.

Desertification is a silent, invisible crisis that is destabilizing communities on a global scale. As the effects of climate change undermine livelihoods, inter-ethnic clashes are breaking out within and across states and fragile states are turning to militarization to control the situation.

Almost one-quarter of the world’s land area has been degraded over the past 50 years because of soil erosion, salinization, peatland and wetland drainage, and forest degradation. The resulting damage, in terms of lost ecosystem goods and services, costs the world an estimated US$6.3 trillion a year. Almost a quarter of the world’s land area has been degraded over the past 50 years.
This is the result of soil erosion, salinization, peatland and wetland drainage, and forest degradation.

Life on Earth depends on healthy soils. The soil under our feet is a living system – home to many fascinating plants and animals, whose invisible interactions ensure our well-being and that of the planet. Soils provide us with nutritious food and other products as well as with clean water and flourishing habitats for biodiversity. At the same time, soils can help slow the onset of climate change and make us more resilient to extreme climate events such as droughts and floods. Soils preserve our cultural heritage and are a key part of the landscapes that we all cherish.

In a world in which poverty is increasingly concentrated in vulnerable or fragile states, and fragility is increasingly driven by climate change, climate-induced displacement has become one of the most visible manifestations of the relationship between ecological and societal breakdown. Newest figures from the Internal Displacement Monitoring Centre reveal that over 70% of the 33 million newly displaced people (2019) had climate-related triggers.

According to the U.N. and World Bank, 40 percent of the global population is affected by water scarcity, and by 2030, up to 700 million people could be displaced as a result.
Having spent his youth spent living through a series of droughts and famine, Ibrahim Thiaw is not only a face to these numbers but also on a mission, as Executive Secretary of the U.N. Convention to Combat Desertification (UNCCD), to ensure that even if the statistics are forgotten, the lands and lives they involve are not.

Between 1981 and 2003, nearly a quarter of global land got degraded, says UNCCD Executive Secretary Ibrahim Thiaw.
