Abstract
Abstract Nigeria is a signatory to the United Nations Sustainable Development Goals (SDGs). Target 6.2 of Goal 6 has requested countries who are parties to the SDGs to end open defecation by 2030. Notwithstanding this, the Government of Nigeria launched a far more ambitious National Road Map in 2016 to end open defecation in the country by 2025. Since water and sanitation are inextricably linked, this paper estimates Nigeria's freshwater requirement to attain open-defecation-free status by 2025. The analysis revealed that the quantity of freshwater required amounted to between 2.74 and 2.94 × 106 cubic metres (m3) per day or between 1.0 and 1.1 × 109 m3 per year under the assumptions made. This amount is relatively less than Nigeria's total water resources potential estimated at 375.1 × 109 m3/year. The data presented will help increase the reliability of estimates of water for sanitation in Nigeria.
Highlights
As a follow up to the Millennium Development Goals (MDGs) that ended in 2015, the 2030 Agenda for Sustainable Development and its Sustainable Development Goals (SDGs), adopted by countries on 25 September 2015, officially came into force on 1 January 2016 (United Nations a)
SDG target 6.2 is far more ambitious than the previous MDG target 7c, which aimed to halve the proportion of the population without access to sanitation by 2015
A state of emergency was declared on the water supply, sanitation and hygiene (WASH) sector on 8 November 2018 to eliminate the business as usual approach
Summary
As a follow up to the Millennium Development Goals (MDGs) that ended in 2015, the 2030 Agenda for Sustainable Development and its Sustainable Development Goals (SDGs), adopted by countries on 25 September 2015, officially came into force on 1 January 2016 (United Nations a). The 2030 Agenda has 17 goals and 169 specific targets addressing social, economic and environmental aspects of development, and seeks to end poverty, protect the Earth and ensure prosperity for all (WHO and UNICEF ) The Government of Nigeria has set a far more ambitious commitment to end open defecation in the country by 2025 through the formulation of a National Road Map (FMWR a) and the Partnership for Expanded Water Supply, Sanitation and Hygiene (PEWASH) (FGN ). A state of emergency was declared on the water supply, sanitation and hygiene (WASH) sector on 8 November 2018 to eliminate the business as usual approach
