In the 1960s, the Green Revolution — which included the development of high-yielding crop varieties, the expansion of irrigation infrastructure and the distribution of modern fertilizers and pesticides to developing-country farmers — bolstered agricultural production worldwide. However, chronic hunger remains pervasive, particularly in developing countries, which are affected most by crop shortages and food-price volatility.
By 2050, the global human population is expected to exceed 9 billion. Achieving food security means ensuring that all people have consistent, affordable access to the right nutrients, despite land and water limitations, climate change and the growing prevalence of resource-intensive Western-style diets that accompany rising incomes.
Surmounting these challenges will not be easy. However, by taking concerted action to encourage innovation, strengthen market linkages and support smallholder farmers and women, developing countries can build productive, stable, resilient and equitable agricultural sectors, achieve sustainable economic growth and guarantee food security for all.
First, the public and private sectors must ramp up investment in research and development, as well as in the extension and adoption of effective, accessible and affordable technologies — whether conventional, intermediate or new-platform — according to each country or region’s individual needs. Given that little suitable land remains unused, and that much of what is being farmed is increasingly degraded and eroded, investment in sustainable intensification (systems for increasing crop yields, while using fewer resources and minimizing environmental damage) is crucial.
For example, conservation agriculture, which aims to reduce or eliminate the need for damaging and labor-intensive interventions like mechanical soil tillage, can increase yields while protecting vulnerable areas from erosion and improving soil fertility.
In Zambia, research conducted by local governments, in collaboration with the anti-poverty charity Concern Worldwide, found that new hybrid seeds produced roughly 4 tonnes to 5 tonnes of maize per hectare, compared with Africa’s average of 1 tonne per hectare.
Moreover, smallholder farmers — who are essential to productive, stable, resilient and equitable agricultural development — should be given the needed tools and support to capture more benefits from value chains, while minimizing risk.
This requires building and maintaining fair and efficient input and output markets that connect them — as well as larger-scale farmers — physically and virtually to opportunities to increase their incomes.
The Alliance for a Green Revolution in Africa has worked with governments, international organizations, charitable foundations, private industry and farmers’ groups to train and support more than 5,000 agrodealers in eastern and western Africa as they open stores to sell key inputs in small, affordable quantities. As a result, farmers can travel shorter distances to acquire needed supplies. In one area of Kenya, farmers who had to travel 17km to reach an agrodealer in 2004 had to travel only 4km three years later.
At the same time, smallholder farmers need easier access to markets to sell their crops for a fair price, rather than relying on expensive middlemen or inefficient government bodies. An alternative would be to establish some form of cooperative or contract-based farm association that can negotiate fair prices.
