The report One Planet Living – The case for Sustainable Consumption and Production in the Post-2015 development agenda, a collaboration between Beyond 2015, Bond for International Development, and BioRegional, argues that sustainable consumption and production need to be included in the post-2015 development agenda that will succeed the Millennium Development Goals.
In this article, researchers consider the impacts of climate mitigation efforts on biodiversity and suggest that the negative consequences could in fact be equal to or exceed the direct effects of climate change on biodiversity. Looking specifically at one of the most likely human responses to curb climate change effects in agriculture - land use - the researchers analyse how changes in agricultural farming practices could impact conservation lands.
A series of studies aiming at assessing and improving agricultural economic models have been published recently in the Proceedings of the National Academy of Sciences (PNAS) and in a Special Issue of the journal Agricultural Economics. These represent the findings of a major international program “The Agricultural Model Intercomparison and Improvement project” (AgMIP) – an effort to produce improved integrated crop, climate and economic models. The AgMIP project links climate, crop, and economic modelling communities with cutting-edge information technology and aggregate crop model outputs as inputs to regional and global economic models. In doing so it is possible to determine regional vulnerabilities, changes in comparative advantage, price effects, and potential adaptation strategies in the agricultural sector.
This study maps the food systems of three capital cities, providing insight for future food security on how population growth, climate change and political instability will affect the open market. The three capital cities examined (Tokyo, Canberra and Copenhagen) and their accompanying capital regions or territories were chosen because they have populations that range over two orders of magnitude, and are situated within different global, climatic and physical locations and socio-economic contexts. The analysis provided is intended to provide a better understanding of the effects of a globally coupled food system.
This FAO key note presentation was given by Andrea Cattaneo at the 3rd Global Conference on Agriculture, Food and Nutrition Security and Climate Change, held in South Africa in December 2013.
In this report the Meridian Institute maps the funding activities of seventeen multilateral, bilateral, and philanthropic donors active in the climate change and agriculture arena. Each donor profile includes:
1) climate change and agriculture activities
2) financing for climate change and agriculture
3) geographic emphases, and
4) donor evolution over time.
This research quantifies the short-term costs of delaying action when confronted with the climate challenge. It concludes that the later climate policy implementation starts, the faster -- hence the more expensive -- emissions have to be reduced if states world-wide want to achieve the internationally agreed target of limiting global warming to 2 degrees above pre-industrial level.
The Living With Environmental Change (LWEC) Climate Mitigation Task Force has released a report which looks at where there might be a need for research activity on geoengineering. The report is a joint production between the Met Office Hadley Centre, University of East Anglia/Natural Environment Research Council and University of Exeter.
In this excellent Guardian article Myles Allen of Oxford University describes and comments on reactions to a paper that he and his colleagues published in the journal Nature Geoscience. Their paper gives a new best estimate for the amount of warming that is expected due to a doubling of GHG concentrations in the atmosphere. It estimates a warming of about 1.3˚C, somewhat lower than previous estimates of 1.8°C.
Tea 2030 project, run by the UK’s Forum for the Future, has published a report identifying 19 factors likely to drive future development of value chain – and it seeks your views.
New Zealand’s temperatures are warming, and its weather patterns shifting – trends consistent with those recorded around the globe. While a reliable water source – our surrounding oceans – will protect us from the severe aridity expected in some other parts of the world, it will not insulate land-based sectors from a more intense and variable climate. Temperatures will continue to warm, and carbon dioxide concentrations will increase.
The UK Energy Research Centre (UKERC), in collaboration with the Glasgow University Media Group and Chatham House has released findings from a qualitative study of audience beliefs and behaviours in relation to climate change and energy security.
Scientists from the American Meteorological Society (AMS) and University of California, Berkeley have demonstrated that plants and soils could release large amounts of carbon dioxide as global climate warms. This finding contrasts with the expectation that plants and soils will absorb carbon dioxide and is important because that additional carbon release from land surface could be a potent positive feedback that exacerbates climate warming.
A paper in Nature Climate Change finds that more carbon dioxide in the atmosphere and rising temperatures cause rice agriculture to release more of the potent greenhouse gas methane (CH4) for each kilogram of rice it produces.
A new study finds that Tanzania is one developing country that could actually benefit from climate change by increasing exports of corn to the U.S. and other nations. The study, published in the Review of Development Economics, shows that Tanzania has the potential to substantially increase its maize exports and take advantage of higher commodity prices with a variety of trading partners due to predicted dry and hot weather that could affect those countries' usual sources for the crop.
