The analysis shows the presence of spatial autocorrelation in rainfall shocks, which compromises the exogeneity of rainfall shocks in many applications. South Africa and the Democratic Republic of the Congo in particular are considered Megadiverse countries. Currently, they are creating 1 km models of rainfall based on the data received from World Community Grid. Other parts of the region average 30 inches of annual rainfall. In this atlas, the African continent is divided into 6 climate types distributed symmetrically around the equator as equatorial, humid tropical, dry tropical, Sahelian, desert and Mediterranean climate types. dry years in 1973, 1982, 1983 and 1992, but also notable differences, for instance in 1985 and 1993. Sub-Saharan Africa has a wide variety of climate zones or biomes. Through the Africa Rainfall Project, researchers at Delft University of Technology will create high-resolution computer simulations of localized rainstorms in sub-Saharan Africa. In the upper right of (a)–(c) is Pearson's correlation coefficient between these time series. Annual rainfall Sub-Saharan Africa has the highest share of rain-fed agriculture globally at 95 percent . We use annual variations in rainfall to examine the effects that exogenous, transitory income shocks have on remittances in a panel of 41 Sub-Saharan African countries during the period 1970–2007.

Africa has approximately 30% of the earth’s remaining mineral resources. African deserts are the sunniest and the driest parts of the continent, owing to the prevailing presence of the subtropical ridge with subsiding, hot , dry air masses. (2004). By 2050, air temperatures are expected to increase throughout maize mega- environments within sub-Saharan Africa by an average of 2.1°C. Temperatures average around 64 degrees year round everywhere except at the more temperate southern tip of the continent and in cooler upland zones. Across the whole of sub – Saharan Africa , maximum 20-yr trends expressed as percent of long-term means have ranged from ±3% per annum for rainfall and from −15% to +11% per annum for river flow (not shown). Whereas in 1993 about 25% of the world’s poorest 5% lived in sub-Saharan Africa, by 2008 it was nearly 60%. The mean age at first marriage is only 18.6 years in sub-Saharan Africa and 17.7 years in India. However, because rainfall in this area is often localized—sometimes almost at the level of one farm—it's difficult to forecast accurately with … Electricity access has fallen for the first time in seven years in sub-Saharan Africa, but a boost to solar power could offer a way forward, says the chief of the International Energy Agency (). Moreover, year-to-year variation in rainfall is a plausibly exogenous shock to Sub-Saharan African economies that is of highly transitory nature: the sample average AR(1) coefficient on rainfall is 0.17 and a distributed lag model shows that the significant effect … Then, your computer contacts the World Community Grid server to let it know that it has completed the simulation, which is then uploaded to our server. The study conducts a household survey of 24 countries in Africa and Sub-Saharan Africa (SSA), a representative of more than half of the African population and two-thirds of the SSA. Development Indicators (2010), the average share of agriculture in value added is about one third in the Sub-Saharan African countries. Here we assess the influence of wetlands on rainfall across sub‐Saharan Africa (SSA). Across the whole of sub – Saharan Africa , maximum 20-yr trends expressed as percent of long-term means have ranged from ±3% per annum for rainfall and from −15% to +11% per annum for river flow (not shown). South Africa Summer temperatures typically average around 82 degrees Fahrenheit (28 degrees Celsius), while winter temperatures hover around 64 degrees Fahrenheit (18 degrees Celsius), with some variation depending on the city. This will help scientists better understand these storms and improve forecasting models. According to the United Nations, it consists of all African countries and territories that are fully or partially south of the Sahara . The findings 1. Results show that all the reanalyses precipitation data sets provide a relatively good representation of the long‐term statistics of spatiotemporal drought characteristics in sub‐Saharan Africa. The central portion of the continent is wetter, with tropical rainforests, grasslands, and semi-arid climates . World Community Grid receives the results you send back (often called work units or research tasks), combines them with hundreds of thousands of results from other volunteers all over the world, and sends them to the Delft research team. The production of crops and livestock other than pigs in Sub-Saharan Africa is typically located in semiarid regions (Barrios et al. Temperatures average around 64 degrees year round everywhere except at the more temperate southern tip of the continent and in cooler upland zones. For sub-Saharan Africa, which has experienced more frequent and more intense climate extremes over the past decades, the ramifications of the world’s warming by more than 1.5° C would be profound.

Join World Community Grid today so you and your computer can help accelerate this vitally important research. Rainfall Variability and Drought in Sub-Saharan Africa Rainfall variability at a time scale from years to days is as much a characteristic of climate as the total amounts recorded. Low values, however, do not necessarily lead to drought, nor is drought necessarily associated with low rainfall. Hence, year-to-year variation in rainfall can have large effects on aggregate incomes per capita and on the return to capital, that go in the same direction, through rainfall's effect on productivity. Location of Sub-Saharan Africa on World Map ... and country-specific time trends. We study the effect of rainfall shocks on intimate partner violence in sub-Saharan Africa. This has never been done for rainstorms in this region. Average precipitation is the long-term average in depth (over space and time) of annual precipitation in the country. The equator runs through the middle of Africa , as do the Tropic of Cancer and the Tropic of Capricorn, making Africa the most tropical continent. Southern Africa has a climate somewhat similar to that of West Africa and southern Sudan. For this purpose, we use panel data and apply econometric methods. Conservation agriculture (CA) has become a dominant paradigm in scientific and policy thinking about the sustainable intensification of food production in sub-Saharan Africa. Rainfall and river flow variability in Sub-Saharan Africa during the twentieth century. The desert valley reached highs of 56.7 degrees in the summer of 1913, which would apparently push the limits of human survival. Sub-Saharan Africa is more vulnerable than any other region to climate change, threatening lives and livelihoods, and undermining economic growth, the IMF chief said on Wednesday. 2008). African Safari - Home Site Map Currency Converter Search Links Blog Africa … However, deficiencies are found in the estimation of drought severity, … It investigates the climate change risks and the use of climate services in decision-making and makes recommendations for actions to enhance the resilience of hydropower schemes. In sub-Saharan Africa, 95 percent of agriculture depends on rainfall, which makes accurate weather forecasts absolutely crucial. In Bots- This average CPIA score for Sub-Saharan Africa remains slightly below the average of 3.2 for other IDA countries. However, because rainfall in this area is often localized—sometimes almost at the level of one farm—it's difficult to forecast accurately with satellite data, which show larger weather patterns. Ultimately, this can lead to more accurate rainfall forecasts for sub-Saharan Africa. The main features of the rainfall climatology in West Africa. Rainfall and vegetation greenness trends were analysed for 759 administrative regions of sub‐Saharan Africa to identify those regions that have experienced a negative, positive or stable rainfall/vegetation trend over the period 2001–2010. Low values, however, do not necessarily lead to drought, nor is drought necessarily associated with low rainfall. It summarises a Dots indicates average across equal-size bins. A significant fraction of women are marrying before age 18: 44.7% and 54.1% in sub-Saharan Africa and India, respectively. capacity in Africa could almost quadruple over the next 20–30 years.3 This policy brief focuses on large hydropower infrastructure in sub-Saharan Africa. Here we review the projected climate change scenarios for Africa’s maize growing regions using the outputs of 19 global climate models. By 2080, Sub-Saharan Africa will be the only region in the world with a … Located just south of the Sahara is a narrow semi-desert steppe (a semi-arid region) called the Sahel, while Africa's most southern areas contain both savanna plains, and its central portion contains very dense jungle (rainforest According to the World Development Indicators (2010), the average share of agriculture in value added is about one third in the Sub-Saharan African countries. Rainfall, brain infection linked in sub-Saharan Africa by Pennsylvania State University Credit: Steven Schiff 2. Africa is the world’s hottest continent with deserts and drylands covering 60% of land surface area (e.g. Rainfall shortage is predominant, occurring when rainfall is average and low. This paper investigates the effects of rainfall shocks caused by climate change on food security in sub-Saharan Africa (25 countries) compared to developing countries (77 developing countries) over the period 1960-2008. Our main finding is that these income shocks have a significant positive effect on remittances, but that the effect is significantly decreasing in the share of domestic credit to GDP. A robust debate about the effects of climate change on conflict occurrences has attained wide public and policy attention, with sub-Saharan Africa generally viewed as most susceptible to increased conflict risk. We use annual variation in rainfall to examine the effects that exogenous, transitory income shocks have on remittances in a panel of 42 Sub-Saharan African countries during the period 1960-2007. The countries of Sub-Saharan Africa belong to the latter group. Highlights We study how climate affects diarrheal prevalence in children in Sub-Saharan Africa. 95% of agriculture in Africa depends on rainfall. And when your computer is idle or not using its full computing power, it will run a simulated experiment in the background. 5 times less than global average of $12,820.29 23.29 million sq km. High levels of absolute poverty—Sub-Saharan Africa has the world’s largest shares of population living under US$1.90 and US$3.10 a day . Required fields are marked *, The scramble for africa describes what event. There were enhanced summer monsoon precipitation in West Africa; increased short rain in East Africa due to the pattern of Indian Ocean warming; increased rainfall extremes of landfall cyclones on the east coast (including Madagascar). Climate in Sub-Saharan Africa Level 1 This article first appeared as part of a textbook with readings about science. April and May form one rainy season, October and November the other. It has a dry winter season and a wet summer season. This is because seventy percent of the continent lies between the tropic of Cancer and the tropic of Capricorn. Sub-Saharan Africa | 39: 384: 2011: Morocco: 149: Middle East & North Africa | 5: 346: 2011: … Downloadable (with restrictions)! There are some common features between this group and Group 2, e.g. Most of sub-Saharan Africa has a tropical climate. The enormous desert spans 11 countries: Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia.The Sahara desert has a variety of land features, but is most famous for the sand dune fields that are often depicted in movies. What is Africa famous for? The starting point of our empirical analysis of Sub-Saharan African countries is that year-to-year variation in rainfall is a shock to agricultural productivity. These vulnerabilities contribute to short term income losses and increased food insecurity. 17% of world Combined Land area. A linear regression line based on the ungrouped data is also shown. Here we assess the influence of wetlands on rainfall across sub‐Saharan Africa (SSA). production in Sub-Saharan Africa is particularly vulnerable to the effects of climate change, with rainfed agriculture accounting for approximately 96 % of overall crop pro-duction (World Bank 2015a). In turn, this could give farmers more timely information about when to plant, help them obtain insurance, and become more resilient in the face of climate change.
