The insatiable hunger for cheap meat
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.

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.
Not only is biodiversity a valuable asset, but it also represents a possible source of income for rural communities. The article shows how Peru is making use of this potential in the context of the BioTrade concept to sustain both, rural livelihood and conservation of native biodiversity. It further analyses the challenges farmers face and how targeted support for supply chains can help to overcome these challenges.
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.
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?
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
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.
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.
