As climate change makes precipitation shocks more common, policymakers are becoming increasingly interested in protecting food systems and nutrition outcomes from the damaging effects of droughts and floods (Wheeler and von Braun, 2013).
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
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.
Accurate biomass estimation is critical to quantify the changes in biomass and carbon stocks following the restoration of degraded landscapes.
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.
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.
Existing approaches and methodologies that investigate effects of land degradation on food security vary greatly.
The results of this study reveal that the full inclusion of crop production in the forest landscape restoration approach could produce largescale,
worldwide benefits for food security and therefore facilitate a wide uptake of restoration practices and the implementation of large
