Food security: solely a water problem?

-

 For my final post, I thought it would provide useful context to consider some of the other factors contributing to food-related issues in Africa to avoid framing it as a one-dimensional problem. This means that many of the solutions I have proposed throughout this blog will not alleviate food issues in Africa in isolation. The factors discussed in this post also play a significant role.

The previous post looked at the potential of virtual water to alleviate food shortages through importing water-intensive agricultural commodities. However, this approach appears far-fetched considering affordability issues of local produce in most African countries. Food affordability is the main driver of food choice and a barrier to consumption of nutritious foods. For example, only 24% of children in Eastern and Southern Africa receive a minimum balanced diet leading to widespread micronutrient deficiencies (UNCF, 2019). Interestingly, evidence suggests that issues of food affordability in Africa are unique. The lowest-spending quintile of Zambian households face far greater affordability barriers than the equivalent group in other countries, whereas affordability results are unchanged between the highest-spending Zambian households and other countries (Ryckman et al., 2021). This frames the food problem as one about access rather than production.

I thought it would be interesting to look at some of the underlying causes of this. From my research, I found that international trade policies have a telling impact on food affordability. African food imports from the EU total $20 billion per year. Agriculture is heavily subsidised in Europe making it cheaper than local produce. African farmers are pushed out of the market whilst dependence on food imports and sensitivity to international food price shocks increases (DPA, 2017). Furthermore, the EU uses escalation tariffs that tax processed commodities at a higher rate than raw ones. This punishes African exporters as they are forced to sell raw goods so don't profit from the significant value that arises during processing (Aziz et al., 2017). For a population so dependent on agriculture for livelihoods, a combination of these factors threatens food affordability.

Following on from the video in my first post, there is an unsurprisingly high correlation between conflict and food issues. The maps below reveal an inverse relationship between average levels of conflict and active cropland. While this is subject to a plethora of geopolitical factors, its impact in Africa is exacerbated due to barriers to investment that prolong the recovery effort. For example, it is widely agreed that infrastructural damage is the driver of current food insecurity in Angola as it hampers food distribution including that of foreign aid (Bowen & Steinberg, 2013).

To summarise, there are factors other than water that contribute to food issues in Africa. However, I hope that this blog has conveyed the potential of water through its depth and breadth of influence. That said, I believe the significance of managing water resources is only set to increase with climate change. Going forward, water could be the critical factor in determining Africa's food security.

Towards an irrigated future: Decolonising water

African nations have adopted a range of innovative solutions to control access to water resources in the face of challenging conditions discussed in this blog. Some have enjoyed more success than others. This post looks at South Africa's system of water permits and, crucially, its impact on the expansion of irrigated agriculture. The water permit system in South Africa is the legacy of colonial histories. Under Dutch rule from 1652 to 1810, water was seen as a public commodity. Between 1810 and 1925, British rulers replaced this with riparian law which favoured land owners. Therefore, water use was divided along racial lines by the end of the 19th century with most water allocated to the white population for commercial agriculture ( Tewari & Oumar, 2013 ). In response, the National Water Act (NWA) of 1998 attempted to balance between efficient use of water, equity and environmental issues, designating the state as the public trustee of the country's water resources.

Water Grabbing

 I concluded my previous post by emphasising the importance of tackling power and control abuses by governments and institutions over communities. This is the first of two posts looking into specific instances of this. Water grabs are the extensive acquisition of land by companies or governments where water is implicitly or explicitly given away with the land. Foreign investors have acquired huge quantities of fertile agricultural land in African countries like Zambia ( Chu, 2012 ). There is conflict over the viability of large-scale investment in Zambia where the aggregate of land deals is equivalent to 12.92% of total arable land, increasing pressures on farmland ( Keane, 2011 ). The common narrative behind these deals is governments from 'finance-rich, resource-poor' nations are turning to 'finance-poor, resource-rich' countries to secure their own future food and energy requirements ( Borras & Franco, 2010: 508 ). However, these land grabs become water grabs as ...

Virtual water: a useful policy tool?

-
Image
So far, this blog has focused on traditional methods of ensuring water and food security like irrigation schemes and groundwater extraction. However, there exist more abstract solutions, including virtual water, that may offer equally promising avenues. Put simply, virtual water measures the water that is 'lost' in the production of any commodity ( Allan, 1997 ). I isolate agricultural commodities due to their water-intensive nature - it requires 1000 cubic metres of water to produce a ton of grain ( Allan, 2003 ). Therefore, virtual water can be harnessed as another method of achieving water and food security. This view argues that the bluewater used in irrigation is an inefficient use of resources when these crops, at least highly water-intensive ones, can be imported from elsewhere ( Zeitoun et al., 2010 ). Whilst we've analysed issues of water and food scarcity on a strictly continental scale, this is a gross simplification of reality. Virtual water allows us to globali...
