In the debate on climate change, it is frequently argued that the number of “climate refugees” is going to grow world-wide. So far, however, only little evidence has been provided of links between climate change, environmental changes and migration. The transdisciplinary research project “micle”– migration, climate & environment – has examined this link in selected areas of the Sahel zone.

German Development Cooperation has developed an approach for the sustainable production of charcoal that has proved to have a considerable impact in Northern Madagascar. Since both environmental and socioeconomic aspects are addressed in a very effective way, this approach has high potential referring to global challenges such as land degradation, rural poverty and climate change.

Tropical forage grasses and legumes as key components of sustainable crop-livestock systems in Latin America and the Caribbean have major implications for improving food security, alleviating poverty, restoring degraded lands and mitigating climate change. Climate-smart tropical forage crops can improve the livestock productivity of smallholder farming systems and break the cycle of poverty and resource degradation.

China has a longstanding tradition of using biogas for decentralised energy supply. Already, there are nearly 42 million household digesters in the rural areas, a figure set to double by 2020. But the country has even more ambitious plans. In order to achieve its own climate targets and raise the share of renewables in overall energy supply to 15 per cent by 2020, it wants to set up 16,000 middle- and large-scale biogas plants. However, implementation isn’t quite so easy.

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.

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.

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.

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.

Every year, 13 million hectares of forest are lost worldwide; that is an area the size of Austria and Switzerland combined. 90 percent of this deforestation involves tropical forests. Forest loss has devastating effects on the climate and is the source of between 15 and 20 percent of global greenhouse gas emissions. If global warming is to be kept below the critical threshold of two degrees Celsius, forest loss and degradation must be halted without delay

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.
