sahel region drought case study

Case study - the impact of drought in a developing country: the Sahel The Sahel is located directly south of the Sahara desert and stretches from the east to the west of Africa.

Understanding the Sahel drought of the late 20th century and improving our future projections for the hydrological cycle in this region is a major challenge for climate dynamics and climate modeling. It has been understood since the 1980's ( Folland, Palmer, and Parker ) that changes in ocean temperature played a significant role in producing ...

Between the 1960s and 1980s severe drought plagued the Sahel, resulting in widespread famine and displacement. Although rainfall has subsequently increased in the region, it is not known whether ...

The Sahel region of Africa has long experienced a series of historic droughts, dating back to at least the 17th century. The Sahel region is a climate zone sandwiched between the Sudanian Savanna to the south and the Sahara desert to the north, across West and Central Africa. While the frequency of drought in the region is thought to have ...

This paper is a critical synthesis of the causes, effects and challenges of the Sahelian droughts. The results show that the four main causes of the Sahelian droughts are as follows: sea surface temperature changes, vegetation and land degradation, dust feedbacks and human-induced climate change. However, human-induced climate change is seen as the major drought-determining factor because it ...

Abstract. This paper synthesizes a set of national case studies conducted in the Sahelian countries during 2019-2020 as a collaboration between national universities and research institutes, and the Center for Development Research (ZEF), University of Bonn, with contributions from the Agrhymet Regional Centre, Permanent Interstate Committee for Drought Control in the Sahel (CILSS).

Since the late 1960s, the Sahel—a semiarid region in West Africa between the Sahara desert and the Guinea coast rainforest—has experienced a drought of unprecedented severity in recorded history. The drought has had a devastating impact on this ecologically vulnerable region and was a major impetus in the establishment of the United Nations Convention on Combating Desertification and ...

One of the first environmental crises to attract interest in development initiatives and aid was the great drought of the 1970s in the Sahel. This study investigates the extent of damage caused by natural disasters from one of the most widely used databases—EM-DAT—with a sample size of 16 Sahelian countries over the period 1960-2020. These countries have been divided into three regions ...

Precipitation in the Sahel declined by ~ 30% in the 1960s, initiating a severe multi-decadal drought that represents one of the most significant climate change episodes in the global instrumental record (Christensen et al. 2013), with devastating socio-economic impacts.The contributions of global warming and land use to this event, however, are still not clearly understood, partly because of ...

DROUGHT IN THE SAHEL The Sahel is one of the world's most vulnerable drought hazard regions. Drought hazard can be defined as a condition of abnormally dry weather, resulting in a serious hydrological imbalance. The consequences for people can include loss of standing crops, water shortages for livestock and human populations, and damage

The Sahel is a major global agroecological region and its success in adaptation will influence the achievement of the global Millennium Development Goals. From simple typologies of adaptation strategies, our understanding of adaptive capacity has evolved over time (with accumulating observations) into a contextual model which places drought ...

23 January 2022 Humanitarian Aid. Millions of hectares of farmland are lost to the desert each year in Africa's Sahel region, but the UN Food and Agriculture Organization (FAO) is showing that traditional knowledge, combined with the latest technology, can turn arid ground back into fertile soil. Those trying to grow crops in the Sahel region ...

Examining a specific case study in the Sahel region sheds light on the complexities and impacts of desertification. In a particular community, unsustainable farming methods and drought have led to soil erosion and degradation. The once-fertile land has turned into arid, unproductive soil, forcing farmers to abandon their livelihoods and seek ...

The African Sahel experienced a prolonged dr y episode in the latter decades of the. twentieth century, characterised by years in wh ich annual rainfall totals were consistently. below the long ...

The region is semiarid, though less dry and desert like than the Sahara to the north. The Sahel is prone to drought and includes nomadic groups, semi-pastoral farmers/herders, mostly settled communities, and, increasingly, urban areas. Climate change has exacerbated these drought conditions, making the region more susceptible to disruptions.

Due to infrequent rainfall, high temperatures, and degraded land, the Sahel region often suffers from droughts. The Sahel region is considered as one of the world's driest and extreme environmental conditions. In order to assess spatiotemporal vulnerability of potential drought impacts, we used remote sensing and ground station data to evaluate drought conditions in the Sahel region from ...

Scientists say that the current drought in the Sahel began as far back the 1960s. Between the vast Sahara Desert and the dense foliage of the African Rainforest is a band of semi-arid grassland ...

The study area comprises the Sahel ecoclimatic region, mainly the area extending between the longitudes 18°W-20°E and latitudes 10°N-20°N (Fig. 1).In this region, the climate is mainly semi-arid with a short rainy season (4-5 months) and a long dry season.

The case for a new approach to the resilience-challenges of the Sahel has been made elsewhere and will not be documented at length here.2 The two figures annexed (Figure 1 & Figure 2) capture the essence of the drama unfolding in the region. Figure 1 documents the increase in the frequency and severity of food crises in recent years and the ...

Burkina Faso - desertification. This video shows the Sahel region south of the Sahara is at risk of becoming desert. Elders in a village in Burkina Faso describe how the area has changed from a fertile area to a drought-prone near-desert. The area experiences a dry season which can last up to eight or nine months.

The northern Sahel region is experiencing a 30-40% annual departure from normal rainfall. 25-30% below that, and 20-25% in the southern Sahel. Human factors act like a feedback loop. Humans enhance the impacts of drought by the over-abstraction of surface water from rivers and ponds, and of groundwater from aquifers. Key human factors ...

The 1983 drought in the West Sahel: a case study. Ju¨rgen Bader•Mojib Latif. Received: 3 June 2009/Accepted: 27 October 2009/Published online: 12 November 2009 Springer-Verlag 2009. Abstract Some drought years over sub-Saharan west Africa (1972, 1977, 1984) have been previously related to a cross-equatorial Atlantic gradient pattern with ...
