Bush encroachment is a matter of growing concern in the semi-arid regions of Namibia. Locally adapted, long-term solutions for land restoration must be elaborated. It is crucial that local scientists are empowered to map and monitor the degradation process themselves, our authors maintain.

Every year in Africa, nearly 3 million hectares of forests are lost and sixty five percent (65%)
of the land is affected by degradation. An estimated 3 percent of GDP is lost annually from
soil and nutrient depletion on cropland. This places forest loss and land degradation among
the key challenges facing Sub-Sahara Africa (SSA). Exacerbated by climate change and
poor management of agricultural lands, forest degradation threatens the water supplies and
ecological functions vital to all SSA economies. Rural smallholder farmers and households

Due to recurring droughts and severe overgrazing, Jordan’s dry rangelands are exceptionally prone to degradation. Establishing both restoration and sustainable rangeland management practices are crucial to reverse the negative impacts on the ecosystem. However, a primary estimate of the native baseline’s water and sediment fluxes is essential to properly target a sustainable transition from degraded to a potentially revegetated landscape status.

Healthy soils are essential for productive and resilient agricultural systems. They are also increasingly recognized as a means to mitigate climate change risks. While solutions for restoring degraded soils and landscapes do exist, improved knowledge and tools are needed to enhance their impacts over time and at scale. WLE has assessed the impacts of various land restoration initiatives and developed a range of tools to better tailor and target investments and interventions to local contexts.

In the United States 20% of privately owned rangelands are vulnerable to accelerated soil loss. Estimated annual costs of direct and indirect damage caused by soil erosion in the United States is $27 billion dollars. More than 50% of Asia and 70% of Middle Eastern rangelands are degraded. Exact estimates of economic costs and total area degraded is unknown; however, costs may be significantly higher than in the United States due to the extent of degradation/desertification in these regions.

La conservation et la gestion durable de la forêt font partie des grandes priorités de développement de Madagascar. Néanmoins, la problématique de la déforestation et de la dégradation des forêts reste cruciale pour diverses raisons, liées notamment au contexte socioéconomique du pays, à la gouvernance des ressources naturelles et à la politique de développement.

The Asia-Pacific region, despite impressive economic growth, is home to 490 million people still suffering from chronic hunger and it accounts for 62 percent of undernourished people in the world. Other trends and topics that need to be taken into account include population growth, urbanization and change of dietary patterns, issues of malnutrition and food safety, climate change and disaster risk, and unsustainable production and environmental degradation.
