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.

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 in this predicament in terms of ‘adaptive capacity’? Solving the water-access-for-food-production problem will no longer suffice under climate change. It is extreme climate events which are the chief drivers of increasing acute food insecurity and malnutrition of millions. Between 2015 and 2019, an estimated 45.1 million people in the Horn of Africa and 62 million people in eastern and southern Africa required humanitarian assistance due to climate-related food emergencies.  The focus on food production also omits the significance and vulnerability of wild-harvested foods which simply rely on uncultivated ecosystem dynamics functioning uninterrupted. Non-timber forest products are consumed by an estimated 43% of all households in Burkina Faso and wild vegetables accounted for about 50% of total vegetable consumption in south-eastern Burkina Faso. Those non-cultivated species, while a source of food, will not have the benefit of farmland irrigation schemes. Communities in the Kalahari and Zimbabwe also report scarcity of wild foods due to drought.

Availability and price of seeds, lack of knowledge and training, and even inadequate labelling of seed supplies - a host of non-climatic factors, prevent effective adoption of resilient agricultural practices, such as diversifying crop varieties to more drought-tolerant ones. Looking to non-agricultural work for additional income can help household finances seasonally but often proves maladaptive at large and long term. For example, some take up charcoal production, increasing deforestation and carbon emissions. Whether off-farm activities constitute maladaptation depends on whether resources are available to upgrade skills or support investments that make a new business more lucrative. Without such resources, this option may lead to impoverishment. It is clear, therefore, that water access alone, while essential to food production, cannot ensure food security.

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.

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 ).              Colocynth fruit growing in the Sahara;  Source : Britannica.  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 to...
