    It is encouraging to see that the United Nations Security Council is beginning to acknowledge the transboundary dimensions of fragility and conflict, as demonstrated by its newly launched Report of the Secretary-General on the situation in the Lake Chad Basin region.

    Drought and vegetation dynamics in the northern Xinjiang Uygur Autonomous Region of China (NXC), the centre of Asia with arid climate, were assessed using the standardized precipitation evapotranspiration index (SPEI) and the normalized difference vegetation index (NDVI). Analyses were performed through the use of Sen’s method and Spearman’s correlation to investigate variations in the NDVI and the impacts of drought on vegetation from 1998 to 2015.

    Limiting global warming to well below 2 degrees Celsius and better even to 1.5 degrees Celsius, according to Article 2 paragraph 1 of the Paris Agreement requires global zero emissions in a very short time. These targets imply that not only emissions from degraded peatlands have to be avoided, but conservation and rewetting of peatlands are also necessary to figure as sinks to compensate for unavoidable residual emissions. However, with regard to instruments for meeting these targets, measuring, depicting, and baseline definition are difficult for greenhouse gas emissions from peatlands.

    Nos systèmes alimentaires vivent un moment critique : l’ampleur et le rythme des changements qu’ils subissent au niveau mondial, régional, national et local sont sans précédent. Ils évoluent rapidement pour s’adapter à une demande croissante et changeante, mais ils ne répondent pas aux besoins de chacun. Au moment de mettre sous presse ce rapport, une nouvelle menace émergeait dans le monde : l’épidémie de coronavirus.

    Climate change is shaped and understood through assumptions of causality and temporality that enable and constrain feasible approaches to environmental governance, approaches that may reproduce inequalities. Reducing Emissions from Deforestation and Forest Degradation (REDD+) provides an entry point to examine the intersecting assumptions and politics around climate change and how it is managed. Actors in the REDD+ regime promote particular assumptions about the causality and temporality of climate change, which are often privileged over local ways of being and knowing.

    L’Afrique de l’Ouest et centrale abrite 25 % des forêts tropicales de la planète. La déforestation y est une préoccupation centrale au défi climatique. Face à cette menace, des lois nationales visent à protéger et à restaurer les forêts, ainsi qu’à encadrer leur utilisation pour le développement national.

    Climate change has led to more severe conditions throughout the world as well as in Morocco. In general, rainfall has declined and average temperatures have increased. These new rainfall patterns are threatening water supplies. Fluctuations and reductions in annual rainfall have led to severe and frequent droughts throughout the Central and West Asia and North Africa region. Consequently, water resources have become scarce. Increasing municipal and industrial demand for water has resulted in steadily decreasing allocations for agriculture.

    Agro-ecosystems in dry areas are sensitive to changes in climate
    and land use. The productivities of these agro-ecosystems are
    highly variable in both spatial and temporal scales. Accurate and
    up-to-date information on these production systems at farmscape to
    landscape scales are important for understanding the food security
    and sustainability of socio-ecological systems. Due to lack of such
    information, satellite remote sensing has been used to quantify the
    land productivity and degradation dynamics of agro-ecosystems

    Nomadic pastoralism is a precarious lifestyle and a significant form of land use involving some form of mobility within extensive rangeland areas (WISP, 2007). Pastoralism provides 10% of the world’s meat production and supports approximately 200 million households worldwide (FAO, 2001). A declining trend in pastoralism with a shift to sedentary agro-pastoral practices on smaller tracks of land and its major implications on rangeland management have been noted by the authors across many regions.
