Introduction to the blog


Food production is intrinsically linked to water – when agricultural water supply or access dwindle, or dip suddenly, food security follows the trend soon after (World Bank, 2020). Sustainable Development Goal (SDG) 2, focusing on expanding global food security, has brought about intensive initiatives, which demonstrate the critical need for irrigation for food production globally. Agriculture across Africa is dominated by smallholder farmers, which make up some 60% of Sub-Saharan population and even more in other regions. Implementing SDG2 will require as much as 65 billion dollars in irrigation alone (Goedde et al., 2019).

African realities will draw on case studies from across the nations of the continent and report the figurative good, the bad and the ugly of water, as it pertains to food production. Africa is well suited for exploration of this topic, spanning a wide range of climatic conditions, from deserts to bi-annual rainy seasons in the Inter-Tropical Convergence Zone (ITCZ), and diverse geology, determining natural water storage capacities. Uganda, with ITCZ’s red soils not conducive to water storage fundamentally relies on water input from the plentiful rainfall it receives (Gumoteyo and Nayebare, 2020). Meanwhile there are huge aquifers of water beneath the Sahara Desert (McGrath, 2012) with virtually no rainfall. At the same time, African nations have the lowest, both, ratio of populations with access to safe water and per capita food production.  Agricultural productivity is key to structural transformation oriented towards growth. This year economy of Sub-Saharan Africa was estimated to expand by 3.6% and 3.1% in Eastern and Southern regions (World Bank, 2022).

 A note on ‘water scarcity’ metrics

Most commonly, water scarcity simply means that the demand for renewable freshwater exceeds supply, which is estimated using mean annual river runoff.  Realistically accurate water scarcity predictions, encompassing the politics involved in distribution of access and hydrological variability, are particularly important in African countries as the ramifications of water scarcity prove more severe in such climates (Damkjaer and Taylor, 2017). When used here, I mean to emphasise scarcity of water for agricultural irrigation and hence food production, rather than meaning that people do not have drinking water. 

African realities vs Africa’s reality

As Binyavanga Wainaina (2005) reminds us of and pokes fun at in his satire piece, Africa is not one place. There are 54 countries with over 1.4 billion diverse people (UN, 2022), inhabiting some of Earth’s most ill-served climates and hydrogeology. Africans can present the most realistic accounts of their national ‘socio-ecological systems’ (Ostrom, 2015) and local realities; publications such as Sahel Quarterly are an example. In this blog, over the coming weeks, I want to focus on authentic narratives and fact reporting, to render a multidimensional picture of water and food across the continent.

Integrated water management for food security

' Water is both an indispensable input and a key constraint ' .   As illustrated in previous entries, the current water condition in Africa, as it pertains to food production, needs more efficacy in water management, and increasingly so, due to climate change effects on hydrology. Expansion of irrigation, particularly groundwater, could be an effective adaptive strategy for the growing population. However, inherent hydrological inequalities pose great challenges and droughts threaten rain-fed livelihoods where potential for irrigation is limited. There exist methods of enhancing rain- fed productivity but they employ temporally and water quality sensitive approaches which are difficult to maintain.          (top)  Farming in Western Sahara; Source : Getty Images; (bottom) half-moon dam/swales in a field, used to save water during rainfall, Burkina Faso; Source : FAO.

African voices on the global climate arena - COP27

Global climate change influences freshwater availability and demand in Africa. This short entry briefly summarises the  African realities  of food systems as described in a  UNFCC report  prepared for Conference of Parties (COP27) in Sharm el-Sheikh, Egypt, with author list featuring prominent African experts.       COP 27 sign; Source : Scientific American Cry me a river - would water solve all problems? The report critiques the preoccupation with food production, as has also been my own focus in this blog, and calls for close consideration of other aspects of food security such as storage, processing, distribution and consumption. Rapid population growth and increasing urbanisation across the continent will also have collateral impacts on water in food systems and hence food security.  The previous entry already outlines the nexus of climate change, water, and food production, largely citing this report.  What do Africans think they need...
