Without transformative change like the Asian Green Revolution, African food systems will continue to impede human development
Global food systems have been battered by overlapping crises in recent years. Key among these are the COVID-19 pandemic, the Russo-Ukraine war and extreme weather events resulting from climate change. These have resulted in forced migration, loss of employment, climate stress, loss of biodiversity, and economic instability.
In Africa, which is home to 1.5 billion people, these shocks and stressors have slowed – or even reversed – decades of progress in improving food security and nutrition. For example, 37 million people in the Greater Horn of Africa are facing acute hunger in one of the region’s worst droughts in decades.
These multiple crises have forced the world to recognise that improving nutrition and food security requires more resilient global and national food systems. Food systems are the sum of actors and interactions along the food value chain — from input supply and production to transport, processing, retailing, wholesaling, preparation, consumption and disposal.
As set out in the Sustainable Development Goals (SDG2), the journey towards food and nutritional security for Africa has a clear destination – zero hunger. The target is to ensure access to safe, nutritious and sufficient food for all people by 2030.
The recently launched Africa Agriculture Status Report examines the continent’s progress towards food and nutritional security.
We co-edited the report, which has six key themes. It charts a roadmap to get to the goal faster while adapting to a changing environment. Our report coincided with World Food Day 2022, whose theme is safer food, better health.
Without transformative change like the Asian Green Revolution, African food systems will continue to impede human development. They will also continue to be overly dependent on food imports. Without a strong drive for sustainable agricultural practices, the continent’s food systems will worsen environmental destruction. Urgent action is needed to anticipate megatrends, rally political will, mobilise investments and strengthen capacity.
Development practitioners working in Africa need true cost accounting for our food systems. It should explicitly consider all the environmental, social and human health outcomes associated with the way food systems are organised. For example, 74 per cent of agricultural production growth in sub-Saharan Africa since 2000 has been achieved through area expansion and only 26% from increased yields. This is far from ideal. Reliance on area expansion has converted forests and grasslands into cropland on a massive scale. The result has been substantial damage to the region’s stock of natural resources and ecosystem services.
A true cost accounting framework sets out the costs of this approach. It would lead to the recognition that technical innovation is important to improve yields on existing farmland. It would show that this is a more sustainable approach to production growth, better health and improved nutrition.
African governments must be prepared for the big demographic, economic, environmental, and social trends shaping the continent’s food systems. These include:
rapid population growth, associated land scarcity and rapidly rising land prices
rapidly growing demand for food, driven by rapidly growing urban areas, rising incomes and purchasing power
more frequent and intense weather disruptions associated with climate change
global health crises, economic disruptions, and civil conflicts such as the Russo-Ukraine war
technical innovation in digital agriculture.
Africa’s food systems continue to evolve in response to these drivers. Food policies and investment strategies need to change too. We are chasing a moving target.
Leadership is essential to harness collective effort, shared responsibility, stakeholder engagement and political will to transform food systems.
Political leaders can either push the accelerator or step on the brakes. The complex nature of our food systems requires that key actors, including national governments, international agencies, civil society, farmer organisations and the private sector, work together towards the common goal.
Governments and regional bodies are at the centre of food systems interventions.
Financing is the fuel needed to accelerate transformation. Based on recent estimates from New Growth International, a network based management consulting firm, food systems transformation in Africa requires up to US$77 billion a year from the public sector and up to US$180 billion from the private sector.
Mobilising financing at scale requires African governments to:
commit to financing priority actions
enhance coordination between government and private sector
ensure good governance and accountability.
Africa must invest in domestic human, institutional and system-wide capacities and capabilities. Capacity development efforts should be guided by seven core principles: country ownership and leadership; alignment with national needs and priorities; use of national systems and local expertise; no “one-size-fits-all” tactics; multi-level approaches; and mutual accountability.
We also note that even though agricultural research capacity has increased by 90% between 2000 and 2016 there has been a decline in public investment in agricultural research systems. This threatens Africa’s capacity to adapt the latest technologies to local conditions.
There’s an urgency to transforming African and global food systems to make them more resilient and sustainable. Failure is not an option.
Transformation will require a coordinated approach from governments, development partners, the private sector and civil society. It is time to put into action the carefully designed strategies, policy reforms and investment plans highlighted in the latest report.
