Final Thoughts

-
I have sadly come to the end of my blogging journey. In this post, I will briefly reflect on what has been covered and future trajectories.
 
Needless to say, the topic of water and food in Africa is extremely broad. Throughout my blog, I have explored the various ways in which nations across Sub-Saharan Africa (SSA) have sought to improve agricultural productivity and food security using different water management, extraction and distribution techniques. By focusing on individual nations for each case study and considering their unique situations, I have tried to avoid the all-too-common treatment of Africa as if it were one homogenous nation.

Upon reflection, I realise that my earlier posts are largely focused on institutional-level interventions and policies including virtual water trading, integrated water resource management and desalinisation schemes. Whilst these are effective to an extent, they do not always explicitly consider the needs of smallholders. As these farmers play a crucial role in agricultural production in several nations, I shifted my focus to solutions that considered their needs more directly, specifically with the cases of genetically modified crops and groundwater irrigation. 

Water Scarce or Rich? 

As seen in Figure 1, the prevailing issue in Sub-Saharan Africa appears to not be physical water scarcity but economic water scarcity. According to Rijsberman (2006), this occurs when water resources are adequate but investment in water infrastructure is not. This type of water scarcity certainly seemed to be present in a number of my case studies, notably for groundwater in Zambia.

These findings support the call to move beyond the application of Falkenmark's WSI and develop a more holistic water scarcity metric that is more representative of the actual situation on the ground. Maintaining the false rhetoric of physical water scarcity in SSA will only hinder progress and misguide attempts to improve nations' water and food security. 

Future Trajectories

I hope that my case studies have shown that there are many effective methods to improve food security in different nations across Africa, even in the some of the world's most challenging environments. It is also vital that scholarship moves beyond the false axiom of Africa being in constant need of Western aid. In order to be equitable and sustainable, strategies should use a combination of scientific, local and indigenous knowledge whilst considering the different needs of all stakeholders. 

There are many more ways through which food and water insecurity can be addressed than the five that I have explored in this blog. Even the most popular methods are not suitable for every environment. As mentioned in my opening post, Africa is an incredibly diverse continent and each nation has their own unique topography and socio-economic environment to which agricultural producers must adapt. Moving forward, it is imperative that these unique conditions are considered.

On a personal note, I have found this blogging journey to be a valuable opportunity to learn more about one of my areas of interest. I hope it has been equally interesting to read!

Why Water and Food in Africa?

  Welcome to my blog where I will be exploring the complexities of water and food in Africa. I hope to offer insight into some of the strategies being employed to address both water and food security in countries across the continent.   Water  Water is integral to humanity. It covers 71% of the Earth's surface but only 0.5% of this is  available  freshwater .  Different climates and physiography have produced an inequitable distribution of freshwater worldwide. Africa is home to 20% of the world’s population but has just 9% of total renewable freshwater .  To put this into perspective, the United States accounts for only 4.5% of the population yet 8% of renewable freshwater . Although freshwater levels have remained relatively stable (~3% of all water) since the Mesozoic era, population growth has resulted in a threefold increase in its use .  Faced with the growing uncertainty resulting from climate change, it is now more...

Virtual Water Trade: A Solution to Kenya's Agricultural Dilemma?

Kenya is said to be in crisis: a water crisis . This has veritable implications for the country's food production and security.  It is therefore  imperative that freshwater resources are better managed and distributed . This  post will consider the potential of Virtual Water Trade (VWT) in achieving both water and food security in Kenya.  Water in Kenya Kenya is generally characterised as water scarce. This has been attributed to a combination of  poor infrastructure, recurrent droughts and most notably, population pressures . With the nation's population predicted to   more than double by 2050 t o 85 million ,  per capita renewable blue water will diminish to 316m 3 , significantly below the quantity needed for an adequate diet. Moreover,  Kenya's freshwater resources are unevenly distributed  ( Figure 1 ). This is especially true for green water: arid northern and eastern regions have  annual precipitation rates as low as 200mm , ...

Seawater & Sunlight: A New Dawn for Somalia's Food Security?

Following my previous post on institutional freshwater management in one of Africa's wealthiest nations, this entry will do a  180° turn to explore a form of small-scale innovation in the continent's  second-poorest nation , Somalia.  Situating Somalia  Somalia is located in the Horn of Africa, one of the world’s most food-insecure  regions.  In past decades, it has been subject to recurrent droughts, water shortages and famine, the effects of which are exacerbated by long-standing civil conflict . Given harsh climatic conditions and incredibly low proportions of arable land , innovative approaches are being piloted as a means of achieving food security in the autonomous region of Somaliland. Here, we turn to Seawater Greenhouse’s desalination pilot project in Berbera.    A Bit About Berbera Berbera is characterised by its hot desert climate and low average precipitation (50mm per annum) . Summer months are intense: temperatures exceed 45 ˚C...
