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.

The livelihoods of many rural dwellers are dependent on having secure and equitable access to land. Tenure security is also a prerequisite for sustainable land management. The massive interest of commercial investors has increased the pressure on land globally. This article describes the international community’s efforts to improve the responsible governance and management of land.

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.

Since 2006, a European Union-wide strategy on soil conservation has been in existence that is to address the complex roles that soil plays as a natural resource. However, a legally binding agreement has so far met with opposition by a blocking minority of EU Member States. Does the EU nevertheless offer prospects for soil conservation?

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.

With more than 900 million people world-wide affected by chronic hunger, international action on soil conservation is urgently required. The United Nations Convention to Combat Desertification (UNCCD) enjoys substantial support, and the author of this article demonstrates that it could play a key role as a global policy and monitoring framework in addressing land and soil degradation.

Zimbabwe used to be well-known for its high-quality meat exports. The sector was hard hit by the economic crisis that set in during the 1990s and coincided with the impact of a failed land reform and recurrent drought. Now, a new livestock-fattening scheme is to contribute to the survival of the branch and help resource-poor smallholders earn a living by marketing their meat.

In order to adequately address the important role of soils and land for sustainable development, a holistic approach is needed. This article discusses why biophysical but also socio-economic aspects have to be considered – using the example of Guatemala, one of the first countries to support the proposal to create the Sustainable Development Goals.

Soil carbon is important for soil structure and related nutrient and water holding properties. Increasing soil carbon stocks results in improved crop growth and contributes to enhanced climate resilience. In addition, the increase in soil organic carbon through sustainable agricultural land management (SALM) practices, such as the use of cover crops, residue management and agroforestry, will also reduce the need for synthetic nitrogen fertiliser at a given level of crop production.

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.

In a world of rapidly changing conditions, enhancing the adaptability and hence the resilience of family farms is crucial to their viability. Here, diversity plays an important role, as the following article demonstrates.

Family farms are often associated with greater sustainability. But the definition of sustainability is a highly disputable topic. The School of Agricultural, Forest and Food Sciences (HAFL) in Switzerland has developed a method enabling a more objective evaluation of sustainability in agriculture. Response-Inducing Sustainability Evaluation (RISE) covers ten sustainability indicators and supplies the foundation for agricultural advice.
