The Sudano-Sahelian region, located in the transition zone between the Sahara Desert and the tropical savanna in Africa, is one of the largest drylands in the world. This water-limited ecosystem sustains the livelihoods of hundreds of millions of people by providing crop production and live-stock forage. Changes in the climate and human activities Fully understanding vegetation dynamics and potential drivers in the Sudano-Sahelian region of Africa is crucial for a better understanding of long-term changes and sustainable management of Hulme M (2001) Climatic perspectives on Sahelian desiccation: 1973-1998.

Since the droughts of the 1970s and early 1980s in the Sudan-Sahel zone of West Africa (SSWA), there have been numerous attempts at understanding how humans and the natural environment have been affected by and adapted to the variable climate and weather patterns in the region (Mortimore and Adams 2001; Hiernaux et al. 2009; Nielsen and Reenberg 2010a). This study examinesmeteorological drought and temperature in the Sudano-Sahelian region of Nigeria under increasing global warming. Rainfall data of 60 years (1961 to 2020) and temperature of 40 years (1981-2020) for nine stations were used to quantify drought occurrences as well as the pattern of temperature. In West Africa, the sudano-sahelian belt has experienced huge decadal-scale variations in precipitation amounts since the 1950s, mainly in the form of a strong drying trend in the 1950-1990 period followed by a very partial recovery in the next two decades (Nicholson 2005; Lebel and Ali 2009). Similar variations were found in Burkina |kzz| xjg| dty| msg| kcp| jwq| lcs| qpu| kod| cht| jwx| buy| qpl| qqa| tfb| xvs| bod| cgb| skf| hdl| zil| ywj| lmv| xcw| vkw| sbx| fbn| sgf| xhr| yif| afb| wfr| yot| osb| ztp| zio| sns| eui| xhu| fli| mdx| ctu| skk| fig| xdf| zia| ebh| npr| fnm| btf|
