A development policy opting exclusively for value chain development and the integration of producers in modern markets overlooks the reality for the majority of smallholders, our author maintains. Policy should pay greater attention to addressing the area most small-scale producers are active in: the informal sector.

Supporting smallholder farmers is one of the best ways to fight poverty and ensure food security. Such support involving the active participation of smallholder farmers in Zambia has demonstrated a significant increase in farmers’ engagement in general and an improvement in milk production, resulting in nutritional food security both at household and national level and income for the poor farmers.

Crop yield improvement is dearly needed in sub-Saharan Africa, but remarkably, African farmers do not adopt the available ‘Green Revolution’ fertiliser technologies. This has many reasons, a crucial one being soil properties.

Soils are naturally poor in sub-Saharan Africa, and poor management has further reduced their productive capacity. The author argues that more fertiliser use is required to reverse further nutrient mining and productivity decline and that this agro-input is best used in combination with other measures to ensure that most of its nutrients are taken up by the crop.

The System of Rice Intensification (SRI) is a natural resource management technology that has supporters and opponents. Evidence of the technology’s impacts is mixed. Recent research results from Timor Leste suggest that SRI can improve yields and incomes of smallholder farmers when proper extension systems are in place.

Zambia’s small-scale farmers are even poorer today than they were 40 years ago. According to the 2010 Human Development Report, Zambia is one of just three nations whose development has fallen behind 1970 levels. And yet Zambia is one of Africa’s “lion states” with annual economic growth rates of more than 5 percent. It is not easy to explain such a contradiction, but a DIE study is drawing closer to ? nding an answer.

Twenty-seven nations are classified as ‘water scarce’, a further 16 as ‘water stressed’. This situation, coupled with the fact that many surface and groundwater systems are shared between two or more states, has led governments to develop sustainable water management strategies. This implies a real commitment by all water users – households, farmers, and industrialists – to use available supplies in ways that reap sustainable and equitable benefits for all.

Carbon labels for food are a new strategy of industrialised countries to reduce climate change-relevant gas emissions in agriculture. However, not every label includes the measurement of all emissions and may disadvantage and even exclude exporting farmers from developing countries. Policy-makers should reconsider this approach or at least focus on fair and non-discriminatory labels.

Not only has soil degradation in Niger been halted thanks to an integrated approach combining water harvesting technologies, the application of organic residues and planting of fruit trees and vegetables. The strategy has also enabled increases in farmers’ income as well as an active involvement of the country’s largely marginalised women in food production through their gaining access to land.

More than three times as much carbon is stored in soils across the world as it is in the atmosphere, making them one of the most important global carbon sinks. Therefore, processes impacting on the soil in which carbon is released, such as deforestation or agricultural activities, significantly contribute to climate change. The debate on the reduction of greenhouse gas emissions from agricultural activities and their consideration in the international climate negotiations has brought soils as carbon reservoirs more to the public eye.

Nerica – New Rice for Africa is the name of the great biotechnological success in rice breeding. What scientists created in the lab using modern methods, namely hybrids of African rice and Asian rice, had already come into being decades ago by chance in West African ?elds.

Since the 2008 food price crisis, foreign investors have been acquiring more and more land in poor countries for producing foodstuffs and biofuels for their own use. Such investments have the potential to promote rural development and food security worldwide. By the same token, however, there is the danger of countless small farmers losing their land, of food insecurity increasing in many places, and of social and ecological systems collapsing through pure "land grabbing".
