Improving watershed conservation and household food security has been one of the major development challenges in the semi-arid areas of northern Ethiopia. The initial survey by ILRI’s Improving Productivity and Marketing Success project has revealed that physical conservation measures alone do not result in higher farmers’ income. However, the introduction of market-oriented commodity development such as beekeeping, sheep-fattening, and high value crops resulted in farmers’ income rising fivefold from 2005 to 2009.

If the current trend in global meat demand persists, meat production will need to rise from 300 million tons today to 470 million tons by 2050. Climate and our natural resources would lose out, our author warns.

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.

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.

King prawns are a delicacy worldwide, but some breeding processes are responsible for extensive environmental damage, especially in mangrove forests. The widespread use of antibiotics also has a negative impact on human health. The cultivation of 'organic prawns' could be a real alternative.

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.

Climate change is one of the major threats to the development of rural Africa, and without wide-ranging adaptation strategies the challenge it presents cannot be met. Although appropriate measures have been identi? ed, international funding for adaptation has not materialised at the rate that was pledged. This is irresponsibly delaying the implementation of adaptation measures.

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.

Soils around the world are degrading rapidly, reducing ecosystem diversity and some important functions, threatening food and other human securities, and increasing vulnerability to climate change. This is a vicious cycle created by and leading to further unsustainable land-use practices. Integrated (‘nexus’) soil, land, water and ecosystem management can help to turn it into a virtuous cycle.

The importance of forests for climate change mitigation and species conservation, as water stores and oxygen producers, soil protectors and humus providers, is well known. However, over 13 million hectares of forest are lost each year, mainly in the tropics.

Rangelands cover 30 per cent of the global land surface. They support a considerable share of the global ruminant value chains, are habitat for a high plant and animal diversity and have various ecological, economic and social functions. But rangelands are currently under pressure from global change processes. A focus on humananimal- environment interactions is necessary to avoid resource overexploitation and degradation.

In rural areas of many developing countries fuelwood constitutes the only energy source – often with negative impacts on humans and the environment. Wise management and modern technology can guarantee a sustainable use of this valuable resource, as some examples from Latin America demonstrate.
