c. 2348 BCE The Flood 0 cit. In Ussher's chronology the flood of Noah begins in 2348 BC and the ark comes to rest on the mountains of Ararat. The tradition records that Noah, his family, and the animals aboard the ark survive. environment / religion ●●●●

c. 1201 BCE The Pastoral Neolithic in the central Rift 6 cit. Before ironworking farmers arrived, herders kept cattle, sheep, and goats across the grasslands of the central Rift Valley. Louis and Mary Leakey excavated sites like Hyrax Hill and the Njoro River Cave cremation cemetery, defining the Elmenteitan tradition alongside the broader Savanna Pastoral Neolithic. Stone bowls, pottery, and burials show a settled herding world centuries before the Iron Age. environment / science ●●●

c. 1001 BCE El Molo settle Lake Turkana as fisher-foragers contested 5 cit. The El Molo are held to have reached the Turkana Basin from the north around 1000 BCE, speaking a Cushitic language related to those of Ethiopia and Somalia. In the arid lakeshore country they turned from herding or farming to fishing and hunting hippo, crocodile, and turtle. Whether they were always foragers or specialised into fishing after arriving is not settled. environment / exploration / society ●●

c. 701 BCE The word ocean descends from the god Oceanus legendary 0 cit. The Greeks pictured Oceanus as a Titan and a great river encircling the world, and his name gives us the word ocean. The Atlantic likewise recalls the Titan Atlas and the Aegean the legendary king Aegeus. culture / environment ●●

c. 1000 Bantu farmers settle the Taita Hills contested 3 cit. The Taita are a Bantu-speaking people who settled the isolated Taita Hills, a set of forested mountain blocks rising above the dry Tsavo plains. They grew out of several waves of migrants who clustered into tight hill communities and terraced the slopes for farming. The exact make-up of these early groups is reconstructed from language and oral tradition, so the details are debated. environment / society ●●

c. 1000 The Ogiek as forest-dwelling Southern Nilotic hunter-gatherers of the Mau contested 5 cit. The Ogiek (Okiek) are a Kalenjin-related, Southern Nilotic people long settled in the highland forests of the Mau Escarpment and around Mount Elgon. Their own traditions say they were always in these forests, while some scholars trace an earlier movement south from the highlands north of Lake Turkana. Whether they are an aboriginal remnant of the region or a Southern Nilotic group that specialised in forest foraging is debated. culture / environment / society ●●

c. October 1347 Black Death reaches Europe 0 cit. Genoese ships carry plague from the Black Sea to Sicily, and within five years the disease kills perhaps a third to half of Europe's people. Labor shortages, social upheaval, and religious crisis follow, loosening the medieval order. environment / society ●●●●●

c. 1492 The Columbian Exchange reshapes two worlds 0 cit. Sustained contact set off a two way transfer of crops, animals, people, and diseases between the Americas, Europe, and Africa. Old World epidemics killed most of the Indigenous population, while American crops reshaped diets worldwide. environment / science / society ●●●●

c. 1492 The Columbian Exchange 0 cit. The contact between the Old and New Worlds set off a vast transfer of crops, animals, people and diseases across the Atlantic. Old World epidemics killed a large share of indigenous Americans, while new crops reshaped diets worldwide. environment / society ●●●●●

c. 1500 Marakwet furrows carry mountain water down to a dry valley 0 cit. The Marakwet built a network of gravity-fed irrigation furrows that draws water from streams rising in the Cherangani Hills and carries it down more than a thousand metres into the dry Kerio Valley. The system is thought to be several centuries old, with dozens of channels running for tens of kilometres, historically built and repaired with wood, stone and packed earth. It let farmers grow sorghum, millet and other crops in country too dry for reliable rain-fed farming. economy / environment / technology ●●●

c. 1600 The Aweer as hunter-gatherers of the Lamu hinterland 3 cit. The Aweer, known to outsiders by the exonym Boni, are a Cushitic-speaking people who lived by hunting, gathering, and collecting honey in the forests between Lamu and the Somali border. Most of their food came from wild plants, roots, and honey, with hunting adding meat. Their Aweer language belongs to the Cushitic branch of Afroasiatic. culture / environment / society ●●

c. 1700 The Yaaku as Cushitic cave-dwelling foragers of Mukogodo 1 cit. The Yaaku lived by hunting, gathering, and beekeeping in the Mukogodo forest of Laikipia, sheltering in rock caves that gave rise to the name Mukogodo, roughly people who live in the rocks. They spoke Yaakunte, an Eastern Cushitic language unrelated to the Maa of surrounding pastoralists. Honey and forest game anchored their economy. culture / environment / society ●●

c. 1700 Aweer use honeyguide birds to find wild honey 3 cit. The Aweer are known for working with the greater honeyguide bird, following its calls and answering with whistles to locate wild bees' nests in the forest. Honey was both a staple food and a trade good. This partnership with a wild bird is one of the best-known human-animal cooperations in Africa. culture / economy / environment ●●

c. 1700 Councils of elders share out Marakwet furrow water by clan 0 cit. Furrows are owned and maintained by clans, and the work and the water are divided among them by long-standing rule. Councils of elders, the kokwo, decide the turns for taking water, organise repairs and settle disputes over shares. This customary management kept a scarce resource working for the whole community across generations without written law. environment / society ●●

c. 1730 The Norfolk four-course crop rotation spreads 0 cit. Landowners such as Charles Townshend promoted a rotation of wheat, turnips, barley, and clover that kept fields productive without fallow years. Turnips and clover also fed more livestock through winter. economy / environment ●●●

c. 1750 The Ogiek and their honey economy of the Mau Forest 4 cit. Honey sits at the centre of Ogiek subsistence, ritual, and exchange. Families keep named beehive sites in the forest, tapping different flowering zones through the year, and honey served as both food and a form of currency. Hunting and gathering rounded out a livelihood tied closely to the forest's seasons. culture / economy / environment ●●

c. 1750 Drought pushes the Keiyo up the escarpment 0 cit. The Keiyo first settled at the foot of the escarpment between the Kerio River and the high wall of rock. Drought and famine in the valley drove many to climb the escarpment and settle the cooler highland plateau toward Uasin Gishu. The result was a way of life spread across two zones, the dry valley floor and the wet highland above. environment / society ●

1769 to 1770 The Bengal famine of 1770 0 cit. Drought combined with the East India Company's rigid revenue demands to produce a famine that killed roughly a third of Bengal's population. The Company kept collecting taxes as millions starved. economy / environment ●●●

c. 1800 to c. 1900 The great coalfields power industry 0 cit. Coal from fields in the Midlands, the north of England, Wales, and Scotland fueled steam engines, furnaces, and homes. Cheap, plentiful coal underpinned the whole industrial economy. economy / environment ●●●●

c. 1800 to c. 1850 Industrial cities and slums grow rapidly 0 cit. Towns such as Manchester, Leeds, and Glasgow swelled as people arrived to work in factories. Crowded, unsanitary housing bred disease, and cholera outbreaks swept the slums. environment / society ●●●●

c. 1800 The El Molo fishing life on Lake Turkana 0 cit. The El Molo fished the lake from rafts lashed together out of doum-palm logs, using spears, harpoons, nets, and woven baskets. Unlike their pastoralist neighbours they kept no cattle and rarely ate meat, drawing most of their food from the water. They traded fish and ivory to nearby herders for milk, meat, and livestock. culture / economy / environment ●●

c. 1845 to c. 1852 The Great Famine in Ireland 0 cit. A potato blight caused mass starvation while food was still exported and government relief fell short. Roughly a million people died and millions more emigrated, permanently scarring Ireland. environment / society ●●●●●

3 March 1849 Founding of the Department of the Interior 0 cit. Congress creates a home department to manage public lands, Indian affairs, patents, and pensions as the country expands westward. Interior becomes the chief steward of federal lands and natural resources. environment / politics ●●●

c. 1850 Keiyo work two worlds, valley farms and highland herds 0 cit. The Keiyo built a livelihood that moved between the escarpment top and the valley floor. On the highland they kept cattle and grew grain in the wetter climate, while in the hot Kerio Valley they cultivated with the help of irrigation furrows like those of the neighbouring Marakwet. Moving stock and labour between the zones spread risk against drought. economy / environment ●

c. 1872 The chigoe flea reaches Africa 0 cit. The chigoe flea, or jigger, native to South America, took hold in Africa when a ship dumped ballast sand from Rio de Janeiro on the Angolan coast. Earlier introductions during the slave trade had died out; this one spread. The burrowing flea causes tungiasis, painful and disabling foot infestations. environment / society ●●●

1873 Founding of Rio Tinto 0 cit. British investors buy the ancient Rio Tinto copper mines in Spain from the Spanish government and float the company in London. It becomes one of the world's largest mining groups. economy / environment ●●

c. 1880 Cash-crop and extraction economies 0 cit. Colonies were reshaped to export raw materials and cash crops such as cotton, cocoa, rubber and palm oil to Europe. Taxes and forced cultivation pushed people into growing for export rather than food, leaving economies dependent and unbalanced. economy / environment ●●●

c. 1883 Bovine pleuropneumonia reaches the Maasai herds 0 cit. In the early 1880s contagious bovine pleuropneumonia, a lung disease of cattle, spread through Maasailand and began killing animals in large numbers. It was the first of the linked disasters the Maasai later remembered as the Emutai, the wiping out. The sickness struck a society whose whole economy and diet rested on healthy herds. economy / environment ●●●

c. 1889 Jiggers spread east across the continent 0 cit. Within two decades the jigger crossed Africa along caravan and trade routes, carried by porters and soldiers. Stanley's Emin Pasha Relief Expedition is credited with helping spread it into the Great Lakes region. It reached most Central, West, and East African colonies, and Madagascar by 1899. environment / society ●●●

c. 1891 The great rinderpest panzootic destroys the cattle contested 0 cit. Around 1890 to 1891 the rinderpest panzootic that swept down Africa reached the Maasai and killed the great majority of their cattle in a matter of months. Herds that had numbered in the thousands were reduced to a handful of survivors. Contemporary and later estimates of losses running above ninety percent of the cattle are widely cited but hard to verify precisely. economy / environment ●●●●

c. 1892 Smallpox sweeps the starving survivors 0 cit. With the cattle dead and people weakened by hunger, smallpox spread through the Maasai and killed many who had survived the loss of their herds. The disease hit crowded, desperate camps of people who had lost the means to feed themselves. It deepened a collapse that struck at families, herds and leadership together. environment / society ●●●

c. 1894 Drought and famine complete the Emutai contested 0 cit. Drought and famine finished what disease had begun, and the Maasai remembered the whole ordeal as the Emutai. Some accounts, including that of the missionary observers, suggested that a large share of the Maasai died in these years, with figures such as half or two-thirds sometimes quoted. Such death-toll fractions are estimates and remain disputed among historians. environment / society ●●●●

c. 1900 Jiggers reach Kenya with the caravans and the railway 0 cit. The jigger arrived in the East African interior with caravan porters, soldiers, and the Uganda Railway during the conquest. It caused crippling foot infestations among communities already broken by rinderpest, smallpox, and famine, adding disease to the disruption of colonization. environment / society ●●●

19 May 1900 London convention frames African hunting as a crime 0 cit. European powers signed the Convention for the Preservation of Wild Animals, Birds and Fish in Africa, setting rules for game across their colonies. In the East Africa Protectorate it fed game laws that licensed white sport hunters while treating African subsistence hunting as poaching. The same act that a Maasai or Kamba family used to feed itself became a punishable offence, and killing wildlife for meat was recast as a crime against the state. environment / politics / society ●●

c. 1900 The long Pokomo-Orma contest over the river 3 cit. Farmers and herders on the Tana have long competed for the same narrow strip of watered land. The Pokomo plant crops on the banks, while the Orma need to bring cattle to the river to drink, especially in drought. This clash of farming and grazing along one river has been a recurring source of tension for generations. economy / environment ●●

c. 1900 The Aweer of the Boni forest 0 cit. The Aweer, or Boni, are a small hunter-gatherer people of the Boni-Dodori forest in Kenya's far northeast. They lived by foraging, hunting and gathering wild honey, long tied as clients to Oromo and Somali herders around them. In recent decades they have been squeezed by forest conservation rules and by army operations against militants in the same forest, cutting them off from the land they depend on. environment / society ●●

c. 1906 Colonial game reserves clear people from the land 0 cit. The protectorate set aside large game reserves such as the Southern Reserve, following the Yellowstone idea that true wilderness holds no people. Africans who had lived, grazed and hunted in these areas were pushed to the edges or moved out. The model treated human presence as a threat to nature rather than part of it, an ideology later called fortress conservation. environment / politics / society ●●

25 August 1916 Founding of the National Park Service 0 cit. Congress creates a single agency to manage the national parks and monuments, which had grown haphazardly since Yellowstone became the first national park in 1872. The service is charged with keeping the parks unimpaired for future generations. environment ●●●

c. 1930 Colonial forest reserves cut the Ogiek off from the Mau 4 cit. British forest and game policy gazetted much of the Mau as protected reserve and treated the resident Ogiek as squatters with no title. Restrictions on hunting and residence began to sever the community from the resources they had always used. The state did not recognise the Ogiek as a distinct people with land claims. environment / politics / society ●●

c. 1931 Gold is found in the North Kavirondo native reserve 4 cit. Prospectors confirm workable gold deposits near Kakamega, inside the North Kavirondo reserve that had just been set aside for the Luhya. Word spread quickly through the colony and beyond. The find sat on land that the 1930 ordinance had supposedly placed off limits to outsiders. economy / environment ●●●

c. 1943 to c. 1944 The Bengal Famine 0 cit. Around three million people died of starvation in Bengal amid wartime disruption, hoarding, and government failure to divert food. It was one of the deadliest famines under British rule. environment / society ●●●●●

1943 to 1944 The Bengal famine of 1943 0 cit. Wartime policies, hoarding and the diversion of food and shipping caused a famine that killed around three million people in British-ruled Bengal. Relief was slow and inadequate as the empire prioritized the war effort. economy / environment ●●●

1 July 1946 Operation Crossroads at Bikini Atoll 0 cit. The United States begins postwar nuclear testing at Bikini Atoll after relocating its inhabitants. The islanders never return permanently, opening a long legacy of displacement and contamination in the Marshall Islands. environment / war ●●

December 1946 Nairobi National Park becomes Kenya's first 0 cit. Kenya gazetted Nairobi National Park, the country's first national park, on the plains south of the colonial capital. Maasai who grazed cattle across the area lost access to a stretch of their dry-season range. The park set the template for later ones, drawing a hard line between protected wildlife inside and the people kept outside. environment / politics / society ●●●

5 October 1948 Founding of the International Union for Conservation of Nature 0 cit. Governments and conservation groups, encouraged by UNESCO, sign an act at Fontainebleau creating the International Union for the Protection of Nature, now IUCN, keeper of the Red List of threatened species. diplomacy / environment / science ●●●

April 1948 Tsavo gazetted as a vast protected wilderness 3 cit. The colonial government created Tsavo National Park, one of the largest protected areas in the world at over twenty thousand square kilometres. Kamba, Orma and other communities who used the land for grazing, hunting and honey were excluded from the new park. Its sheer size showed how much territory the wilderness-without-people idea could remove from local use in a single stroke. environment / politics ●●

1948 Tsavo becomes a park and the Waata become "poachers" 3 cit. When Tsavo was gazetted as a national park in 1948, land the Waata and Orma had used became off-limits and Waata hunting was recast as criminal poaching. Colonial authorities pursued Waata hunters, with sweeps in the mid-1950s driving them out of the park. Barred from their grounds and unlicensed, they lost the basis of their livelihood. environment / politics / society ●●

1 March 1954 Castle Bravo test 0 cit. The largest American nuclear test yields 15 megatons, far beyond prediction, and showers fallout on Rongelap islanders and a Japanese fishing boat. The disaster galvanizes the global movement against atmospheric testing. environment / war ●●●●

1959 Serengeti and Ngorongoro evictions push the Maasai out 0 cit. When the Serengeti National Park was fixed in 1959 the Maasai living inside it were moved out and resettled in the neighbouring Ngorongoro Conservation Area. There they faced tightening limits on grazing and cultivation in the name of protecting wildlife. It began a long pattern in Tanzania of treating Maasai land use as a threat to conservation. environment / politics ●●●

29 April 1961 Founding of the World Wide Fund for Nature 0 cit. Julian Huxley, Peter Scott and fellow conservationists create the World Wildlife Fund, opening its first office at IUCN headquarters in Morges, Switzerland, to raise funds for protecting endangered wildlife. diplomacy / environment ●●●

1961 The Maasai Mara reserve takes the northern grasslands 0 cit. The Maasai Mara was set aside as a wildlife reserve on the Kenyan side of the Serengeti ecosystem and later enlarged. Grazing was restricted across some of the richest Maasai pasture so that wildlife and tourism could take priority. The reserve became a symbol of how land the Maasai depended on was turned into a protected asset managed largely for outsiders. economy / environment ●●●

c. 1961 Maasai pushed out of the Mara 0 cit. The Maasai Mara was set aside as a wildlife sanctuary and then a game reserve on Maasai grazing land in the southwest. Herders lost secure access to pasture and water in the core of the reserve, which was managed for tourism and wildlife. The Mara became one of Kenya's most famous parks and one of its clearest cases of pastoralists displaced for conservation. economy / environment / society ●●

1961 The Maasai Mara stays a county reserve, not a private park 2 cit. The core Maasai Mara was placed under local authority reserve management rather than made a Kenya Wildlife Service national park. That legal detail matters: the Mara is not private land, but a county reserve whose revenue, access rules and management contracts sit with local government. The private-looking part grows around it later, where subdivided Maasai land is leased into conservancies and tourism blocks. economy / environment / politics ●●●

27 September 1962 Publication of Silent Spring 0 cit. Rachel Carson publishes Silent Spring, documenting the damage pesticides do to ecosystems and human health. The book ignites the modern environmental movement. environment / science ●●●●

c. 1962 Ecology and environment 0 cit. Climate, pollution, biodiversity, land health, and the limits of extraction. The environment is not a side issue: it sets the conditions inside which every other pillar can function or fail. environment / pillar ●●●●●

1963 Independence and the loss of Yaaku forest rights 1 cit. With Kenyan independence in 1963 the Yaaku lost the protections that had loosely held the Mukogodo forest as their ground. Land and forest policy favoured other interests, weakening their claim to the ancestral woodland. Marginalisation as a small, absorbed community continued under the new state. environment / politics / society ●

2 July 1966 Moruroa's first nuclear test 0 cit. France detonates Aldebaran from a barge in the Moruroa lagoon, moving its testing from the Sahara to the Pacific. Nearly two hundred tests over thirty years leave lasting contamination and Polynesian resentment. environment / war ●●

April 1968 Club of Rome founded 0 cit. Scientists, economists, and business figures formed the Club of Rome to study global problems such as resource use and population. It is best known for commissioning influential reports on the limits of growth. economy / environment ●●●

13 December 1968 Garrett Hardin publishes The Tragedy of the Commons 0 cit. Ecologist Garrett Hardin argued in a 1968 essay that shared resources are inevitably overused and that population growth had to be limited, questioning voluntary restraint. His argument became a widely cited justification for coercive population policy. environment / science ●●●

1968 Paul Ehrlich publishes The Population Bomb 0 cit. Biologist Paul Ehrlich's 1968 bestseller The Population Bomb warned that overpopulation would cause mass famine and collapse within decades. Its dire predictions did not come to pass, but the book fueled decades of alarm and support for aggressive population control. environment / science ●●●●

1969 Founding of Friends of the Earth 0 cit. David Brower founds Friends of the Earth in San Francisco after leaving the Sierra Club over its stance on nuclear power. In 1971 it became an international network now active in over 70 countries. diplomacy / environment ●●

3 October 1970 Founding of NOAA 0 cit. A Nixon reorganization plan combines the Weather Bureau, coastal survey, and fisheries service into the National Oceanic and Atmospheric Administration within the Commerce Department. NOAA becomes the nation's weather, ocean, and climate agency. environment / science ●●

2 December 1970 Founding of the EPA 0 cit. Nixon's reorganization plan pulls pollution programs from across the government into a single Environmental Protection Agency. Armed with the new Clean Air and Clean Water acts, the EPA becomes the enforcer of American environmental law. environment / politics ●●●

22 April 1970 First Earth Day 0 cit. Some twenty million Americans join demonstrations and teach-ins for the first Earth Day. The event turns environmentalism into a mass movement and precedes a wave of environmental legislation. environment / society ●●●

1971 Founding of Greenpeace 0 cit. Canadian and American activists in Vancouver charter a boat to protest US nuclear testing at Amchitka, Alaska, founding the campaign that became Greenpeace, the global direct-action environmental organization. diplomacy / environment ●●●

15 December 1972 Founding of the UN Environment Programme 0 cit.

March 1972 The Limits to Growth published 0 cit. The Club of Rome published The Limits to Growth, a report using computer modeling to warn that unchecked growth could strain the planet's resources. It became one of the most widely discussed environmental studies of its time. environment / science ●●

March 1972 Club of Rome publishes The Limits to Growth 0 cit. The Club of Rome's 1972 report The Limits to Growth used computer models to warn that population and economic growth would exhaust the planet's resources. It became a foundational text for the movement to restrain both growth and population. economy / environment ●●●●

3 March 1973 CITES 1 cit. Convention regulating international trade in endangered species of wild animals and plants through a permit system. It protects tens of thousands of species. diplomacy / economy / environment ●●●

c. 1973 Endorois evicted from Lake Bogoria for a game reserve 0 cit. The Endorois community was moved off its ancestral land around Lake Bogoria so the area could become a game reserve for tourism. They lost access to the lake, its salt licks and the grazing central to their pastoral life, and received little compensation. The eviction cut a small community off from the place at the heart of its culture and religion. environment / politics / society ●●

6 February 1973 Earthquake strikes Luhuo County in Sichuan 0 cit. A magnitude 7.6 earthquake struck Luhuo County in the Garze region of western Sichuan. It leveled much of the county town and surrounding villages. Reports placed the death toll at roughly 2,200 people. environment / society ●●

c. March 1973 The great Mississippi River flood inundates the lower valley 0 cit. Heavy spring rains sent the Mississippi River over its banks in one of the worst floods on the lower river since 1927. The river stayed above flood stage for record stretches at St. Louis and downstream. Millions of acres were flooded and damage ran into the hundreds of millions of dollars. The strain nearly overwhelmed the Old River Control Structure in Louisiana. environment / society ●●

c. 1973 The Sahel drought and famine reach their peak 0 cit. Years of failed rains across the Sahel brought famine to a peak in 1973, spanning Mauritania, Mali, Niger, Chad, Upper Volta, and Senegal. Crops and herds were devastated and millions of people were displaced. Reports estimated that the drought killed well over 100,000 people across the region. It spurred a large international relief effort. environment / society ●●●

1974 Amboseli is fenced off and the Maasai lose the swamps 0 cit. The Amboseli basin, long used by Maasai herders for dry-season water and grazing, was gazetted as a national park in 1974. Herders were pushed out of the central swamps and springs that had kept their cattle alive in drought. Promised benefits and water schemes were slow and partial, and the Maasai lost reliable access to a key refuge. economy / environment ●●●

1974 Amboseli made a national park and the Maasai removed 0 cit. Amboseli, a key Maasai dry-season refuge around its swamps, was gazetted as a national park by presidential decree. The Maasai were barred from grazing cattle in the central basin they had relied on for generations. It became a textbook example of how a herding landscape was turned into a fenced tourist attraction, with the herders left outside. economy / environment / society ●●

1976 Reserves and hunting bans restrict Aweer forest use 3 cit. The gazetting of the Boni and Dodori national reserves, together with Kenya's hunting ban, cut the Aweer off from lands and game they had long relied on. Forced toward settlement and farming in a dry, marginal area, many faced food insecurity. The community's foraging economy was steadily squeezed. environment / politics / society ●●

May 1977 Kenya bans hunting and hardens the poaching line 0 cit. Kenya banned all hunting, ending licensed sport hunting but also cementing that any local killing of wildlife was poaching. Communities living beside parks now bore the cost of crop-raiding elephants and lost livestock with no legal way to use wildlife. Enforcement focused on catching African hunters, while the earlier era of licensed white hunters was over. environment / politics / society ●●

1977 Wangari Maathai founds the Green Belt Movement 1 cit. Wangari Maathai launched the Green Belt Movement under the National Council of Women of Kenya, paying rural women to plant trees and restore degraded land. What began as an answer to fuelwood shortages and soil erosion grew into a wide grassroots network. The movement tied care for the land to women's livelihoods and civic organizing. environment / society ●●●

1977 Kenya's 1977 hunting ban forces the Ogiek toward farming 5 cit. Kenya's nationwide ban on hunting outlawed a core part of Ogiek subsistence and pushed many families into settled agriculture and livestock keeping. Combined with continued eviction from reserved forest, the ban reshaped a way of life built on mobility and the forest. Some Ogiek kept beekeeping alive alongside the new crops. economy / environment / politics ●●

1 April 1979 Founding of FEMA 0 cit. Carter's reorganization merges scattered disaster and civil defense programs into the Federal Emergency Management Agency. FEMA becomes the federal face of hurricane, flood, and earthquake response, and joins Homeland Security in 2003. environment / society ●●

1983 Anna Merz and the Craigs start the Ngare Sergoi rhino sanctuary 0 cit. Anna Merz, together with David and Delia Craig, sets aside part of the Craig family's Lewa Downs cattle ranch as the Ngare Sergoi Rhino Sanctuary. It is a response to heavy rhino poaching in Kenya. The sanctuary is the seed from which the Lewa conservancy and the wider northern conservancy movement grow. environment ●●

1984 Kuki Gallmann turns Ol ari Nyiro into a private conservancy 3 cit. The Italian-born author Kuki Gallmann founds the Gallmann Memorial Foundation and converts her family's Ol ari Nyiro ranch, roughly 100,000 acres on the edge of Laikipia, into the Laikipia Nature Conservancy. It is one of the best-known examples of a single foreign-linked family holding a very large block of northern Kenyan land under a conservation banner. environment / society ●●

1985 to 1993 The Narmada dam controversy 0 cit. World Bank funding for the Sardar Sarovar dam drew fierce protest over the displacement of tens of thousands of people and environmental harm.
