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.

The purpose of this thesis is to examine the nature and scope of the linkages between the resource environments, livelihoods and food security of households and individuals. These are analyzed using the livelihood systems framework with the biophysical environment as the entry point. The biophysical and socio-economic environments are investigated as the conditioning and influencing factors that help define the relationships along the production-consumption continuum. The context is spatial, in this case that of fragile areas, where most of the poor and food insecure live and work.

Dust storms are capable of transporting sediment over thousands of kilometers, but due to the Middle East and North Africa (MENA) region’s proximity to the Sahara Desert, the region is one of the dustiest in the world. While natural sources such as the Sahara are the main contributors to dust storms in MENA, land-use changes and human-induced climate change has added anthropogenic sources as well.

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

Les dynamiques migratoires dans les zones agricoles, liées à la conjugaison de facteurs structurels et conjoncturels, prennent de l’ampleur et posent de nouveaux défis dans la gestion des conflits fonciers. Les mécanismes traditionnels et modernes de gestion foncière doivent régulièrement se renouveler et s’adapter, afin de résoudre efficacement et durablement les différends fonciers causés par les déplacements de populations.
