Ten years after the first Year Book in this series appeared, a special e-book anniversary edition – UNEP Year Book 2014 – presents a fresh look at ten issues highlighted over the past decade.
A top China government advisor said at a recent Beijing conference that China, the world's biggest greenhouse gas emitter will limit its total emissions for the first time by the end of this decade. The Chair of China's Advisory Committee on Climate Change said that an absolute cap on emissions will be introduced sometime within the next five years. Although the advisor later stated that these were only his own opinions, commentators expressed a cautious optimism about the statement.
The CCAFS (CGIAR research program on Climate Change, Agriculture and Food Security) newsletter Agriculture-Climate Letters - A Science-Policy Bulletin, is a valuable resource for those interested in receiving further updates on the links between food and climate –with a particular focus on developing countries. In their latest issue Sonja Vermeulen, CCAFS head of research, highlights the special issue of Environmental Research Letters on mitigation in the agriculture and land use sectors in developing countries.
New official data from the European Union shows a 19.2 % reduction on GHG emissions on 1990 levels, suggesting that the union is within reach of its target to reduce emissions by 20% until 2020. Emissions fell by 1.3 % between 2011 and 2012, largely due to reductions in transport and industry and a growing proportion of energy from renewable sources. Italy alone accounted for 45 % of the total EU net reduction in emissions in 2012, largely due to lower emissions from transport and industry.
We include this initiative because it addresses the challenges of of ‘closing the food loop’. This innovative solar-thermal toilet was developed by a team led by CU-Boulder Professor Karl Linden to improve sanitation and hygiene in developing countries.
Climate policy progress assessment concludes that many countries are advancing to cut emissions at a similar rate as the UK. A report by the Global Legislators Organisation (GLOBE international) argues that only a "handful of countries" have not yet engaged with climate change as a policy problem or fail to see it as a legislative priority. Analysing the climate legislation of 66 countries (together accounting for 88 percent of greenhouse gas emissions) it finds that 62 of them have a 'flagship law'. And contrary to commonly held perceptions, it is not just rich countries that are introducing laws to tackle emissions. Countries including Ecuador, Costa Rica, Mexico, China, Indonesia, Kazakhstan, and Kenya are also taking firm legal measures.
This dissertation looks at the sustainability of the current food system and analyzes how environmental impacts could be reduced and health impacts could be increased through dietary change. The results from this work suggest that dietary change, in areas with unrestricted diets, could play an important role in reaching environmental and health goals, potentially reducing GHG emissions and land use requirements by up to 50%.
FAO published a new report in September 2013 with revised estimates for GHG emissions from livestock. The “Tackling Climate Change Through Livestock: a global assessment of emissions and mitigation opportunities” report and two accompanying technical reports are long awaited since they include an updated estimate of the livestock sector’s GHG contribution - putting the figure at a lower 14.5 percent of global human-caused emissions, compared to 18 percent in the previous report from 2006.
This policy brief from World Agroforestry Centre (ICRAF) addresses the major challenges of and opportunities for financing climate change mitigation and adaptation pathways for smallholder farmers in developing nations. It underlines the need for an innovative and integrated approach to climate finance that can connect rural farmers to public and private finance at the global level. It also provides recommendations for future actions that can meet adaptation, development and mitigation aims.
This CCAFS blogpost by Timm Tennigkeit and Andreas Wilkes argues that agriculture is a major driver of deforestation, but offers great mitigation potential if managed properly. The authors’ recently released research report finds that emission reduction approaches can also be cost competitive.
Consumers influence climate change through their consumption patterns and their support or dismissal of climate mitigation policy measures. Both climate-friendly actions and policy support comprise a broad range of options, which vary in manifold ways and, therefore, might be influenced by different factors.
A paper published in Nature Climate Change suggests that planting trees for use as a biofuel source, near populated areas, is likely to increase human deaths due to inhalation of ozone. Increased levels of isoprene emitted from such trees, when interacting with other air pollutants can lead to increased levels of ozone in the air which might also lead to lower crop yields.
