   The Lawra district of the Upper West region was selected as the case study. This study compared crop yields for FMNR and non-FMNR farmers. FMNR farmers are classified as having at least 8 trees per acre, with an average of 13 trees per acre (33 per ha) and a maximum of 40. Non-FMNR farmers are classified as having between 1 and 7 trees per acre, with an average of 5.Qualitative (focus group discussion) and quantitative (household survey) data were collected in April to May 2019. Over 500 households were interviewed in both CIKOD intervention communities and control sites.

   Land has a value for each and every one of us. Fertile soil provides us with plant life, vegetables, grains, and fibres. Forests supply us with timber and firewood. We benefit from fresh water, food, and many other ecosystem services that land provides us with. Land is also emotionally valuable to people as well, perhaps through associating treasured memories such as playing on it as a child. In any case, all societies and people assign historical and cultural value to their landscapes, their nature, and all natural phenomena associated with land. However, lands are in danger.

   Land degradation and desertification reduce the provision of ecosystem services by lands and soils. This constrains development, reduces water, food, and energy security, and triggers resource conflicts. Although biophysical processes and economic impacts are increasingly understood, efforts to combat degradation have been failing thus far to prevent further losses of land productivity, a cost estimated at 42 billion USD/year (Dregne & Chou, 1992; Requier-Desjardins, 2007).

   As the world’s population continues to rise, there is
   an ever increasing demand for our land to produce
   a diverse range of products such as food, timber,
   and fuel. Our growing need for these goods is
   leading to higher levels of competition between
   different land uses and, as a result, land users. Not
   only is the quantity of land available for production
   under current technical and economic conditions
   limited, but there is also growing evidence that the
   quality of our land is degrading (Safriel, U. N. 2007;

   Jordan Case Study An economic valuation of a large - scale rangeland restoration project through the Hima system in Jordan

   Jordanian rangelands are a source of valued livestock produce, carbon storage, biodiversity, and medicinal plants. They also serve as watersheds that receive rainfall, yield surface water, and replenish groundwater throughout the area east and south of the western Jordan highlands. Appropriate land management, which is currently lacking, can protect and maximize these services for society. With the acceleration of desertification, land degradation and drought during the twenty-first century in the arid and semi-arid regions of Jordan, these services are becoming jeopardized.

   The Kelka forest in the Mopti region of Mali is important for the provision of ecosystem services like carbon sequestration and maintenance of the hydrological cycle. The Kelka forest area occupies more than 300, 000 hectares with 15
   villages within and around its boundaries. The forest resources and soil fertility of the forest are in continuous decline due to a combination of climatic and human induced factors. For example, the availability of firewood has halved

   Soil erosion and deposition values were estimated using pixel based landscape information and the Unit Stream Power Erosion Deposition (USPED) model, which works with the Universal Soil Loss Equation (USLE) parameters. The USPED model was adapted to Ethiopian conditions based on evidence from the Soil Conservation Research Programme, and calibrated and validated using data from former research stations as well as the Abbay (Blue Nile) Basin. Additionally, some of the USLE parameters were reduced in order to achieve a satisfactory approximation of sediment loss for the Abbay Basin.

   Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

    With around one third of the world’s arable land degraded, estimated annual losses of 6.3 to 10.6 USD trillion, and a projected need to increase food production from land by 70 per cent by 2050, we simply cannot afford to neglect the loss of potential production from careless land management. Whenever land is not producing at its potential,it is an under-performing asset that requires investments to ensure the future supply chains that many industries depend upon.
