Oyo State is bordered to the north by Kwara State, to the east by Osun State, and to the southwest by Ogun State and the Republic of Benin. With a projected population of 7,840,864 in 2016, Oyo State is the fifth most populous in the Nigeria.
In 2020, 97.7% of Indians had access to the basic water and sanitation facilities. India faces challenges ranging from sourcing water for its megacities to its distribution network which is intermittent in rural areas with continuous distribution networks just beginning to emerge. Non-revenue water is a challenge.
The Ugandan water supply and sanitation sector made substantial progress in urban areas from the mid-1990s until at least 2006, with substantial increases in coverage as well as in operational and commercial performance. Sector reforms from 1998 to 2003 included the commercialization and modernization of the National Water and Sewerage Corporation (NWSC) operating in cities and larger towns, as well as decentralization and private sector participation in small towns.
Drinking water supply and sanitation in Benin has been subject to considerable progress since the 1990s, in particular in rural areas, where coverage is higher than in many other African countries, and almost all development partners follow a national demand-responsive strategy, which has been adopted in 1992. New strategies to increase water supply in rural and urban areas have been adopted in 2005 and 2006. Tariffs in urban and rural areas are usually high enough to cover the costs for operation and maintenance.
Drinking water supply and sanitation in Pakistan is characterized by some achievements and many challenges. In 2020, 68% Pakistanis, 72% Indians, 54% Bangladeshi had access to the basic sanitation facilities. Despite high population growth the country has increased the share of the population with access to an improved water source from 85% in 1990 to 92% in 2010, although this does not necessarily mean that the water from these sources is safe to drink. The share with access to improved sanitation increased from 27% to 38% during the same period, according to the Joint Monitoring Program for Water Supply and Sanitation. There has also been considerable innovation at the grass-root level, in particular concerning sanitation. The Orangi Pilot Project in Karachi and community-led total sanitation in rural areas are two examples of such innovation.
Water supply and sanitation in Iran has witnessed some important improvements, especially in terms of increased access to urban water supply, while important challenges remain, particularly concerning sanitation and service provision in rural areas. Institutionally, the Ministry of Energy is in charge of policy and provincial companies are in charge of service provision.
Water supply and sanitation in Israel are intricately linked to the historical development of Israel. Because rain falls only in the winter, and largely in the northern part of the country, irrigation and water engineering are considered vital to the country's economic survival and growth. Large scale projects to desalinate seawater, direct water from rivers and reservoirs in the north, make optimal use of groundwater, and reclaim flood overflow and sewage have been undertaken. Among them is the National Water Carrier, carrying water from the country's biggest freshwater lake, the Sea of Galilee, to the northern part of the Negev desert through channels, pipes and tunnels. Israel's water demand today outstrips available conventional water resources. Thus, in an average year, Israel relies for about half of its water supply on unconventional water resources, including reclaimed water and desalination. A particularly long drought in 1998–2002 had prompted the government to promote large-scale seawater desalination. In 2022, 85% of the country's drinkable water was produced through desalination of saltwater and brackish water.
The water resources of Palestine are fully controlled by Israel and the division of groundwater is subject to provisions in the Oslo II Accord.
Water management in the Metropolitan Region of São Paulo, Brazil faces several challenges, including pollution of drinking water reservoirs that are surrounded by slums, water scarcity leading to conflicts with the Campinas Metropolitan area to the north, inefficient water use, and flooding. The sprawling Metropolitan Region of São Paulo (MRSP) with close to 20 million people is the seventh most populous urban area in the world and the economic, financial and technical hub of Brazil. The main stakeholders in water management in MRSP are the state government, the state water and sanitation utility Sabesp and 39 municipal governments. A basin committee for the Alto Tietê basin, which covers the entire area of the MRSP and supplies half of its water, brings together all stakeholders. It has drawn up two master plans for the management of water resources in the basin. The first was approved in 2003 and focused on urban sprawl. The second was approved in 2009 and focused on water use conflicts.
Chinyere Ike Nwosu was a Nigerian Military Administrator of Abia State and then of Oyo State during the military regime of General Sani Abacha.
Prince Amen Edore Oyakhire was the Military Administrator of Taraba State, Nigeria between August 1996 and August 1998 during the military regime of General Sani Abacha. He was then administrator of Oyo State during the transitional regime of General Abdulsalami Abubakar, handing over to the elected civilian governor Lam Onaolapo Adesina in May 1999 at the start of the Nigerian Fourth Republic.
Adeyemi Ambrose Afolahan was appointed the first Administrator of Taraba State, Nigeria in August 1991 after the state was created from part of the old Gongola State during the military regime of General Ibrahim Babangida. He handed over to the elected civilian governor Jolly Nyame in January 1992 at the start of the Nigerian Third Republic.
Namibia is an arid country that is regularly afflicted by droughts. Large rivers flow only along its northern and southern borders, but they are far from the population centers. They are also far from the country's mines, which are large water users. In order to confront this challenge, the country has built dams to capture the flow from ephemeral rivers, constructed pipelines to transport water over large distances, pioneered potable water reuse in its capital Windhoek located in the central part of Namibia, and built Sub-Saharan Africa's first large seawater desalination plant to supply a uranium mine and the city of Swakopmund with water. A large scheme to bring water from the Okavango River in the North to Windhoek, the Eastern National Water Carrier, was only partially completed during the 1980s.
Responsibility of water supply in Nigeria is shared between three (3) levels of government – federal, state and local. The federal government is in charge of water resources management; state governments have the primary responsibility for urban water supply; and local governments together with communities are responsible for rural water supply. The responsibility for sanitation is not clearly defined.
The Oba River is a river in Oyo and Osun States in Nigeria. It is the main tributary of the Osun River. The landscape varies from wooded savanna in the north to rain forest in the south. The river is heavily polluted. Most of the people who live along its length practice farming and fishing.
Cocoa production is important to the economy of Nigeria. Cocoa is the leading agricultural export of the country and Nigeria is currently the world's fourth largest producer of cocoa, after Ivory Coast, Indonesia and Ghana, and the third largest exporter, after Ivory Coast and Ghana. The crop was a major foreign exchange earner for Nigeria in the 1950s and 1960s and in 1970 the country was the second largest producer in the world but following investments in the oil sector in the 1970s and 1980s, Nigeria's share of world output declined. In 2010, cocoa production accounted for only 0.3% of agricultural GDP. Average cocoa beans production in Nigeria between 2000 and 2010 was 389,272 tonnes per year rising from 170,000 tonnes produced in 1999.
Iranamadu Tank is an irrigation tank in northern Sri Lanka, approximately 3 mi (5 km) south east of Kilinochchi.
Water supply and sanitation in Georgia is characterized by achievements and challenges. Among the achievements is the improvement of water services in the capital Tbilisi where the water supply is now continuous and of good quality, major improvements in the country's third-largest city Batumi on the Black Sea where the country's first modern wastewater treatment plant now is under operation, as well as a general increase in access to drinking water in the entire country. Water and sewer tariffs remain affordable, with the private water company Georgian Water and Power (GWP) serving the capital being financially viable and profitable, while the public water company serving most of the rest of the country remains financially weak. The improvements were achieved after the Rose Revolution of 2004 when the government decided to reform the sector and to invest in it after many years of neglect.
National Policy Dialogues on Integrated Water Resources Management in Azerbaijan for managing water resources are aimed at developing a state strategy based on "Convention on the Protection and Use of Transboundary Watercourses and International Lakes" of United Nations Economic Commission for Europe and European Union Water Framework Directive and the "Water and Health" Protocol of that convention as well as other principles of the United Nations and the EU.
