Législation et politiquesRésolutions de l'ONUaoût, 2019GlobalAs per the provisions of rule 10 of the rules of procedures of the United Nations Convention to Combat Desertification (UNCCD) Conference of the Parties (COP), the second intersessional meeting of the Bureau of the thirteenth session of the COP (COP 13) held in Guiyang, China, on 26 February 2019, endorsed the inclusion of a new agenda item on land tenure, under new and emerging issues, for consideration at COP 14. The Bureau further requested the secretariat to submit a background document in that respect.

Rapports et recherchesdécembre, 2019GlobalThe Sustainable Development Goals (SDGs) adopted by the United Nations General Assembly in September 2015 include a target on land degradation neutrality (LDN) (SDG 15.3). Attaining and maintaining LDN requires addressing a land governance challenge to steer land management towards avoiding, reducing and reversing land degradation.

Publication évaluée par des pairsmars, 2021GlobalFrequent flooding worldwide, especially in grazing environments, requires mapping and monitoring grazing land cover and pasture quality to support land management. Although drones, satellite, and machine learning technologies can be used to map land cover and pasture quality, there have been limited applications in grazing land environments, especially monitoring land cover change and pasture quality pre- and post-flood events. The use of high spatial resolution drone and satellite data such as WorldView-4 can provide effective mapping and monitoring in grazing land environments.

The second phase of the Sustainable Management of Marginal Drylands (SUMAMAD-2) project began in 2009 following a preparatory meeting on the project held on 3–6 June 2008 in Amman and the Dana Biosphere Reserve, Jordan, and was hosted by the Royal Society for the Conservation of Nature (RSCN). The extended SUMAMAD-2 to other world regions included South America (Bolivia) and Africa (Burkina Faso).

The world’s drylands are among the most vulnerable ecosystems on our planet. Desertification and land degradation are affecting huge land areas, jeopardizing the livelihoods of millions of people. Unsustainable management practices in dryland cultivation and pastoralism have given rise to widespread soil erosion, reduction of the biological production of soils, reduction of vegetation cover, and depletion of surface and groundwater resources.

The conference reviewed the current state-of-knowledge of dryland ecosystems; it identified important knowledge gaps for defining future paths of research into drylands; and it commemorated fifty years of dryland research in the UN system in the context of the International Year of Deserts and Desertification. The conference - in a cross-cutting manner - also addressed issues related to research and science needed for dryland conservation, policy options for sustainable dryland development, and necessary interventions and

Millennium Development Goal Number Seven is particularly concerned with the safeguarding and provision of freshwater resources to all human.beings; this is a major challenge – and perhaps even the main challenge – for all the world’s drylands. SUMAMAD project aims at the sustainable management of marginal drylands, where the scarcity of water imposes restrictions for the productivity of each particular ecosystem. It is needed therefore to look into the entire water complex so as to promote a wise and sustainable water use. However,

As marginal drylands, all project sites share similar environmental constraints such as recurrent droughts,
water shortages, shallow soils and the threat of land degradation. As they occur in different economic,
political, social and cultural environments, it will be interesting to address similar bio-physical problems
from different perspectives stemming from varying anthropogenic factors. More importantly, the
