Climate change could potentially interrupt progress toward a world without hunger. A robust and coherent global pattern is discernible of the impacts of climate change on crop productivity that could have consequences for food availability. The stability of whole food systems may be at risk under climate change because of short-term variability in supply. However, the potential impact is less clear at regional scales, but it is likely that climate variability and change will exacerbate food insecurity in areas currently vulnerable to hunger and undernutrition. Likewise, it can be anticipated that food access and utilization will be affected indirectly via collateral effects on household and individual incomes, and food utilization could be impaired by loss of access to drinking water and damage to health. The evidence supports the need for considerable investment in adaptation and mitigation actions toward a “climate-smart food system” that is more resilient to climate change influences on food security.
The marginality concept calls for the integration of poverty concepts with those of social exclusion, geography, and ecology. The difficulties in reaching people at the margins of systems are explained by a set of distances, (i.e., physical distances such as being located in remote or harsh environments), social distances (being excluded, discriminated against, or not having rights or access to services or opportunities), but may also be related to technological and institutional infrastructure deficiencies. A review of policies intended to reduce marginality suggests that none of the marginality determinants need to be accepted as long term. Coherent policies and actions, however, need to match the systemic causality of marginality in order to be effective.
The complex inter linkages between trade and climate change governance are increasingly recognised. Examples in point are emissions trading schemes, border carbon measures, and carbon labelling schemes, and various support measures for clean energy—all climate related policies with possible implications for trade and trade law. Against this background, this information note explores the potential for synergy and cooperation between the trade and climate change regimes. This paper will help those working on climate change to better answer questions such as: How can trade measures better address climate change mitigation? Can current climate response measures restrict trade? And how can a strengthened trade and climate governance make them more constructive?
This book offers a global overview of the present status of action on climate change and on the efforts devoted to develop innovative economic tools. Drawing on the most recent data, this collective book analyses the development of carbon markets in Europe and worldwide and assesses the involvement of major sectors such as agriculture, forestry, transport and housing in the fight against global warming.
In less than a decade, clean energy transitioned from novelty products to the mainstream of world energy markets. The sector emerged not so much in a linear fashion as episodic – in fits and starts associated with the worldwide economic downturn, continent-wide debt crises, national policy uncertainty, and intense industry competition. Through it all, however, the clean energy sector moved inexorably forward, with overall investment in 2012 five times greater than it was in 2004.
Although 2012 investment levels worldwide declined 11 per cent, to US$ 269 billion, the clean energy sector weathered the withdrawal of priority incentives and initiatives offered by governments in numerous key markets, demonstrating its resilience. Reliable clean energy investment data have been collected for nine years now. Looking at the data in three-year increments, average clean energy investment increased by at least US$ 90 billion triennially – from an average of US$ 64 billion in the 2004-06 period to an average of US$ 156 billion in 2007-09 and US$ 245 billion in 2010-12.
