Africa’s Food Future: Bread Basket or Basket Case?

It is one of the strangest paradoxes of my beloved continent: Africa holds the largest tracts of unconverted arable land and yet has the highest levels of malnutrition and food insecurity in the world. The result being that Africa is a net importer of food from countries far less endowed with fertile soils. This is set against the fact that agriculture is by far the most important employer on the continent (up to 70% of jobs) and has the greatest potential to lift Africans out of poverty. How can we reconcile these heart breaking contradictions?

Let’s start with food security….
Most of us tend to think of food security as the ability to produce enough food to meet demand. However, food insecurity in fact has two main dimensions: The one is related to agricultural productivity, the other is socio-economic.

Starting with agricultural productivity: For the most part, Africa has completely missed the so called ‘green revolution’ that saw the modernisation of agriculture and productivity surge in places like Asia, the Americas and Europe (Figure 1).



Figure 1: Agricultural productivity by region
This, set against an Africa with the fastest population growth rates and the highest urbanisation rates in the world, has quite simply left a continent with more people to feed and less food being produced per capita. With Africa’s population set to double to 2 billion in the next 35 years, and urbanisation rates accelerating, this situation is likely to intensify. High urbanisation rates pose a further challenge as the geographic distance between where food is produced and where it is consumed increases. Business as usual is unlikely to be a viable option.
Importantly from an ecological point of view, whilst yield improvements have led to a slowing and even reduction of the spatial area under cultivation elsewhere, low yields in Sub-Saharan Africa have led to a dramatic increase in the area under cultivation and hence conversion of natural areas to agriculture (Figure 2). This conversion has a significant impact on the biodiversity and ecosystem services that these natural areas provide to the poor, such as water provisioning and fuel wood etc.

The second dimension to food security is socio-economic. You see, food security is as much about production as it is about access. To have access, you either need to grow the food yourself (i.e. subsistence farming) or have access to cash to buy it from someone else. Subsistence farming in Africa is a high risk endeavour; the climate is erratic and crops and livestock are vulnerable to pests and diseases. In the past societies were far more nomadic and used this strategy to cope with local climatic variability. Forced into a more sedentary situation, farmers are left with very few options to mitigate these risks. Importantly, financial income levels in rural areas remain desperately low, leaving rural residents with little means to access food from other sources when crops fail. And so, food insecurity is as much about food production as it is about economic diversification and income generation in rural areas.

So what about Climate Change?

Climate change, which is largely as a result of fossil-fuel based industrialisation and wasteful over-consumption of the developed world has left the developing world most vulnerable to its impacts. Africa, is no exception and predicted climatic changes will further impair productivity levels of staple crops such as cereals (Figure 3). Climate variability and the frequency of natural disasters is also predicted to increase making ecosystem based adaptation absolutely essential for ameliorating impacts.

From threat to global opportunity…

Before we get too disheartened, let’s shift our lens on this issue…
As a result of an increasing global population and more specifically the shifting global diet of a growing middle class, the world will need to produce more food in the next 40 years than it has produced in the last 8,000 years combined. Meeting future food needs seems like an impossible task, but it is actually quite achievable…at least mathematically… The solution is threefold: 1) Decreasing global food wastage - which is as high as 50% in many places; 2) Shifting the diets of the growing middle class away from commodities that have the highest ecological footprints, such as red meat; and 3) improving agricultural yields.

Now, to the last point: Africa holds the both the greatest tracts of uncultivated arable land (more than 200 million hectares) and provides the greatest opportunities for increased agricultural productivity on existing agricultural land. Despite this potential, Africa currently contributes only 2% of global food trade and overall is a net importer of food. Even those segments of society most cauterised from purview of capitalism, will recognise this as one the biggest commercial opportunities of our time. Not surprisingly, this has not gone unnoticed, with foreign investors moving swiftly to get their hands on these precious productive lands (Figure 4). Many of these land transactions occur under highly unscrupulous circumstances. This, superimposed on a weak civil society and  a community-based land tenure system that is many cases undocumented, can lead to devastating impacts on the social fabric of rural communities.

Bread Basket or Basket case?

Right now Africa has choices, and the choices Africa makes will determine whether it becomes a bread basket for the world, or a basket case of missed opportunities and food insecurity. In my view, these choices will revolve around five main pivot points

1)     Responsible and pro-active modernisation of Africa’s agriculture sector

Africa has 33 million farms of less than 2 Hectares, accounting for 85% of all farms on the continent (Figure 5). This is very different from Europe and the Americas and more similar to Asia.
Figure 5: Farm sizes across the world
Productivity in Africa remains woefully low compared to the rest of the world, including Asia (Figure 1).  This is a result of a number of factors. Firstly, government budgetary expenditure on agriculture is around 4% in Africa compared to around 14% in Asia. This has led to low levels of modernisation, especially in relation to irrigation (only 6% of crops are irrigated compared to 40% in Asia), mechanisation (30 tractors per 100 km2 compared to more than 100 in Asia and 800 for Europe) (Figure 6), extension support, and the low use of fertilisers, pesticides and modern seeds.
Figure 6: Tractors per 100km2 of arable land
Clearly modernisation brings with it substantial social and ecological risks to rural areas.  However, this needs to be balanced against the impacts of uncontrolled conversion of natural areas to agriculture due to existing low yields and/or uncontrolled ‘land-grab’ style commercialisation that pits large-scale agribusiness interests against disempowered small-scale farmers. Proactive management of the modernisation of Africa’s agriculture sector that is able to find the balance between large scale agribusiness and modernised small-scale producers, will minimise these risks. Furthermore, being a late-bloomer has its advantages, and Africa has the benefit of learning from others that have been down this path. If the transition is managed proactively, Africa should be in a far better position to avoid these impacts.

2)     Empowered Rural Civil Societies

Global agribusiness is dominated by large powerful forces, almost all of which have considerable interest in Africa as the ‘last frontier’ of agricultural expansion. Rural communities in Africa are currently ill-equipped to deal with such forces. Land tenure is often very poorly documented, and communities are not aware of their rights, or how to engage in development planning and impact assessment processes. This will need to change if we are to positively shape Africa’s food revolution.
3)     Creating investor confidence in an African vision for agriculture in Africa.
Modernisation of Africa’s agriculture sector will require a significant and broad-based investment. This investment will only come with investor confidence in a vision for agriculture in Africa that is fit for purpose on the African continent. Current investment climate is seen as either being too risky on the one hand or driven largely by opportunism and self-interest (i.e. the ‘land-grab’ scenario).
Luring the needed broad-based investment into Africa’s agriculture sector will require the development of a vision that is able to: 1) Find the delicate mix of large scale commercial agriculture (which helps to secure lucrative global value chains) blended with small-scale production (which provide employment, poverty relief and social upliftment in rural areas); 2) Effectively deal with land ownership and tenure, and 3) Blend public sector investment into infrastructure with private sector investment in production and supply chains.

4)     Integrated land-use planning and optimisation of the ‘spatial economy’

As competing pressures on finite land resources increase, the importance of solid land-use planning that seeks to optimise Africa’s ‘spatial economy’ escalates. Simply put, not all land is equal. Land is spatially heterogeneous and has inherent assets and values. Some areas have very productive soils, others are critical for their biodiversity, others are important for water provisioning. In South Africa, WWF has found that just 8% of national land surface provides more than 50% of South Africa’s water, and that water supports over 75% of the economy. Clearly the that 8% of South Africa’s land surface should be managed as a national asset of great value. Optimisation of the spatial economy therefore requires land-use planning system that cognizant of the diversity and spatial heterogeneity of values and assets in landscapes.

5)     Building socio-economic and climate resilience in rural areas

As mentioned earlier, food insecurity is as much about food production as it is about socio-economic resilience. This includes access to capital as well as insurance. Only 6% of Africa’s farmers carry any form of insurance against weather or crop failure, making them extremely vulnerable to the increased climate volatility. Micro-finance and index-based insurance will play an important role in building this resilience.
 
Finally, healthy ecosystems will play a critical role in reducing the impacts of climate change. Managing and rehabilitating these ecosystems can both create jobs and financial income in rural areas as well as reduce climate risks – a double whammy for rural resilience in the face of climate change. The successful ‘Working for Water’ programme in South Africa is testament to this, creating over 30,000 jobs whilst at the same time rehabilitating catchments and releasing much-needed water for sustaining ecosystems and economic activities in rural areas.
