A drought is a period of drier-than-normal conditions. A drought can last for days, months or years. Drought often has large impacts on the ecosystems and agriculture of affected regions, and causes harm to the local economy. Annual dry seasons in the tropics significantly increase the chances of a drought developing and subsequent wildfires. Periods of heat can significantly worsen drought conditions by hastening evaporation of water vapour, drying out forests and other vegetation and increasing fuel for wildfires.
A famine is a widespread scarcity of food, caused by several factors including war, natural disasters, crop failure, widespread poverty, an economic catastrophe or government policies. This phenomenon is usually accompanied or followed by regional malnutrition, starvation, epidemic, and increased mortality. Every inhabited continent in the world has experienced a period of famine throughout history. During the 19th and 20th century, Southeast and South Asia, as well as Eastern and Central Europe, suffered the greatest number of fatalities. Deaths caused by famine declined sharply beginning in the 1970s, with numbers falling further since 2000. Since 2010, Africa has been the most affected continent in the world by famine.
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both west and east.
The Sahel region or Sahelian acacia savanna is a biogeographic region in Africa. It is the transition zone between the more humid Sudanian savannas to its south and the drier Sahara to the north. The Sahel has a hot steppe climate and stretches across the southernmost latitudes of North Africa between the Atlantic Ocean and the Red Sea. Although geographically located in the tropics, the Sahel doesn't have a tropical climate.
A widespread famine affected Ethiopia from 1983 to 1985. The worst famine to hit the country in a century, it affected 7.75 million people and left approximately 300,000 to 1.2 million dead. 2.5 million people were internally displaced whereas 400,000 refugees left Ethiopia. Almost 200,000 children were orphaned.
Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution; new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
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 increased from the end of the 19th century, three long droughts have had dramatic environmental and societal effects upon the Sahel nations. Famine followed severe droughts in the 1910s, the 1940s, and the 1960s, 1970s and 1980s, although a partial recovery occurred from 1975-80. The most recent drought occurred in 2012.
A period of unusually hot summer weather occurred in the British Isles during the summer of 1976. At the same time, there was a severe drought on the islands of Great Britain and Ireland. It was one of the driest, sunniest and warmest summers (June/July/August) in the 20th century, although the summer of 1995 is now regarded as the driest. Only a few places registered more than half their average summer rainfall. In the Central England temperature record, it was the warmest summer in the series until being surpassed in the 21st century. It was the warmest summer in the Aberdeen area since at least 1864, and the driest summer since 1868 in Glasgow.
In 2006, an acute shortage of food affected the countries in the Horn of Africa, as well as northeastern Kenya. The United Nations's Food and Agriculture Organization (FAO) estimated on January 6, 2006, that more than 11 million people in these countries may be affected by an impending widespread famine, largely attributed to a severe drought, and exacerbated by military conflicts in the region.
Goure is a town in southeastern Niger, Zinder Region, Goure Department, of which it is the seat.
The 2010 Northern Hemisphere summer heat waves included severe heat waves that impacted most of the United States, Kazakhstan, Mongolia, China, Hong Kong, North Africa and the European continent as a whole, along with parts of Canada, Russia, Indochina, South Korea and Japan during May, June, July, and August 2010. The first phase of the global heatwaves was caused by a moderate El Niño event, which lasted from June 2009 to May 2010. The first phase lasted only from April 2010 to June 2010, and caused only moderate above average temperatures in the areas affected. But it also set new record high temperatures for most of the area affected, in the Northern Hemisphere. The second phase was caused by a very strong La Niña event, which lasted from June 2010 to June 2011. According to meteorologists, the 2010–11 La Niña event was one of the strongest La Niña events ever observed. That same La Niña event also had devastating effects in the Eastern states of Australia. The second phase lasted from June 2010 to October 2010, caused severe heat waves, and multiple record-breaking temperatures. The heatwaves began in April 2010, when strong anticyclones began to develop, over most of the affected regions, in the Northern Hemisphere. The heatwaves ended in October 2010, when the powerful anticyclones over most of the affected areas dissipated.
A large-scale, drought-induced famine occurred in Africa's Sahel region and many parts of the neighbouring Sénégal River Area from February to August 2010. It is one of many famines to have hit the region in recent times.
Occurring between July 2011 and mid-2012, a severe drought affected the entire East African region. Said to be "the worst in 60 years", the drought caused a severe food crisis across Somalia, Djibouti, Ethiopia and Kenya that threatened the livelihood of 9.5 million people. Many refugees from southern Somalia fled to neighboring Kenya and Ethiopia, where crowded, unsanitary conditions together with severe malnutrition led to a large number of deaths. Other countries in East Africa, including Sudan, South Sudan and parts of Uganda, were also affected by a food crisis.
A megadrought is an exceptionally severe drought, lasting for many years and covering a wide area.
2012 had a very severe drought in the Sahel, the semiarid region of Africa that lies between the Sahara and the savannas. Countries included in this region are Senegal, Mauritania, Mali, Burkina Faso, Niger, Nigeria, Chad, Sudan, and Eritrea. Droughts in the Sahel occur quite often and tend to reduce the already meager water supply and stress the economies of developing countries in that region.
In 2022, several areas of the world experienced heat waves. Heat waves were especially notable in East Asia, the Indian subcontinent, Australia, western Europe, the United States, and southern South America. 2022 heat waves accounted for record-breaking temperatures and, in some regions, heat-related deaths. Heat waves were worsened by the effects of climate change, and they exacerbated droughts and wildfires.
During 2022 and 2023 there were food crises in several regions as indicated by rising food prices. In 2022, the world experienced significant food price inflation along with major food shortages in several regions. Sub-Saharan Africa, Iran, Sri Lanka, Sudan and Iraq were most affected. Prices of wheat, maize, oil seeds, bread, pasta, flour, cooking oil, sugar, egg, chickpea and meat increased. The causes were disruption in supply chains from the COVID–19 pandemic, an energy crisis, the Russian invasion of Ukraine and some effects of climate change on agriculture. Significant floods and heatwaves in 2021 destroyed key crops in the Americas and Europe. Spain and Portugal experienced droughts in early 2022 losing 60-80% of the crops in some areas.
The climate of Nigeria is mostly tropical. Nigeria has three distinct climatic zones, two seasons, and an average temperature ranging between 21 °C and 35 °C. Two major elements determine the temperature in Nigeria: the altitude of the sun and the atmosphere's transparency. Its rainfall is mediated by three distinct conditions including convectional, frontal, and orographical determinants. Statistics from the World Bank Group showed Nigeria's annual temperature and rainfall variations, the nation's highest average annual mean temperature was 28.1 °C in 1938, while its wettest year was 1957 with an annual mean rainfall of 1,441.45mm.
