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.

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.

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.

The River Nile provides an invaluable source of livelihoods to over 160 million of people who dwell in its valley. The river valley is renowned for being a cradle of civilisation. As the populations grew and civilisation evolved, the demand for more water resources took a toll in the region. The more recent visible climate change effects have further compounded water management in the basin. Water and food security in the region is under threat, hence the need for robust transboundary water management. An effective institutional arrangement is a key factor in facilitating this process.

Water and soils are increasingly becoming a limiting resource for meeting the food requirements
of a growing world population. Integrated concepts for managing natural resources in a sustainable
and environmentally sound manner show encouraging impacts, if applied on a large scale and
over a long period like in Tigray, the northernmost regional state of Ethiopia.

Poverty in rural households have deepened in the past two years through world events: unprecedented rises in food and fuel prices were followed by global economic meltdown, all amidst growing climate uncertainty. Balancing water availability within and across growing seasons, water harvesting helps to buffer households against drought. Research on water harvesting in South Africa has focused on rural household livelihoods. Innovative results on appropriate water harvesting technologies and food security facilitation techniques are now being implemented in villages across South Africa.

Water is scarce in India's semiarid zones of Rajasthan. Climate change is putting additional pressure on the rare resources. Irregular or no rainfall forces many small farmers to abandon their fields, at least temporarily, and seek work in the towns. Participative water management projects as practiced in Bhipur village, growing crops with low water requirements and more sustainable farming practices are adaptation strategies that allow farmers to continue their activities despite climate risks.

Developing countries, as a group, are the ones most threatened by the hydrological impacts of global climate change. Water is a critical resource in development, and it is affected by climate change in multiple, complex ways ? through changes in temperature and rising sea levels, changes in precipitation patterns, and melting snowfields and glaciers.
