Water is life. Investing in water, sanitation and hygiene is essential for human well-being and economic development. Economist Impact compiled a new briefing paper to highlight the social and economic benefits of investment in water and sanitation services in Africa and to explore funding alternatives for meeting the water investment needs in the region.

The toplines: six key takeaways for Africa’s finance ministers.

1. Investing in water, sanitation and hygiene (WASH) not only serves as a fundamental necessity for public health, education and societal benefits but also generates substantial economic returns of up to 700%. Every US$1 invested in climate-resilient water and sanitation returns at least US$7 for African economies. Sub-Saharan Africa alone could gain more than 5% of its GDP, equivalent to US$200bn annually, if sufficient investment in water and sanitation are made. Historically, the GDP of low-income economies with improved access to water and sanitation services grew much faster (3.7% annually), compared with those without (0.1%).

2. Developing access to safe water and sanitation will disproportionately benefit women and girls, unlocking economic value while advancing gender equality and inclusion. Sustainable Development Goal (SDG) 6 on water and sanitation for all cannot be met without addressing equal access. Across sub-Saharan Africa, women and girls collectively spend around 16m hours per day fetching water, time that could otherwise be spent on education or paid work. This is crucial when we consider that an additional year of education for girls in Africa leads to a 14% increase in future income, compared to an 11% increase for boys.

3. Climate change, population growth and urbanisation all strengthen the economic case for water, sanitation and hygiene investment in Africa. Population growth and urbanisation will both exacerbate the need for adequate water, sanitation and hygiene. Water plays a pivotal role in ensuring food security and is essential for achieving all the SDGs. At least 50% more food and ten times more water for energy production is needed to enable growth and development in Africa. Agriculture, services, manufacturing and energy sectors all stand to gain from supply chain security and increased productivity generated by investment in water, sanitation and hygiene.

4. Water, sanitation and hygiene services save lives and increase productivity. Tackling diarrhoea worldwide can generate US$86bn per year in increased productivity and reduced health costs. This is crucial when considering that 45% of global deaths due to diarrhoea, equivalent to 700,000 people, occur in sub-Saharan Africa.

5. Realising the budgetary resources required is urgent and achievable: at least an additional US$30bn/year needs to be invested across Africa towards water security and sustainable sanitation. Existing plans show this is achievable, with domestic resource mobilisation accounting for US$17.5bn and savings and efficiencies from enhanced sector governance contributing US$11.5bn. This represents an empowering opportunity for national governments, as they can raise US$29bn independently as long as they have access to affordable capital.

6. Governments can drive transformation in the water, sanitation and hygiene sector. The funding challenge in the water sector stems from a historical reliance on projectbased financing and central government support. This challenge, coupled with the limited amount of sector-specific data, has resulted in uneven investment in the water, sanitation and hygiene sector. Governments can explore an approach that encompasses budget programming for the entire sector. This approach ideally includes key aspects such as political commitment, leadership and governance reforms to enhance the attractiveness of water as an investment opportunity.
