El Calentamiento Global, también llamado Cambio Climático, ha generado un gran impacto en la opinión pública. Nos estamos volviendo concientes que el accionar humano afecta el planeta en que vivimos. Indudablemente hay un sinnúmero de impactos producidos en el ecosistema tales como la tala de bosques, la pérdida de flora nativa y el efecto que esto tiene sobre la fauna, la caza indiscriminada, la contaminación del agua y el suelo, entre otros.

Possible consequences of climate change in one of the world?s largest wetlands (Ibera, Argentina) were analysed using a multi-scale approach. Climate projections coupled to hydrological models were used to analyse variability in wetland water level throughout the current century. Two potential scenarios of greenhouse gas emissions were explored, both resulting in an increase in the inter-annual fluctuations of the water level. In the scenario with higher emissions, projections also showed a long-term negative trend in water-level.

Quels types de solutions climatiques pourrions-nous envisager si nous faisions passer les besoins des êtres humains et de la planète en premier? Quelles seraient les solutions appropriées si nous prenons réellement au sérieux le souci d’équité exprimé par l’Accord de Paris?

Hidden in the food we buy every day, from chocolate to ice cream, are commodities like palm oil and soy that are driving deforestation across the world. From Indonesia to the Peruvian Amazon, vast areas of carbon-rich forest are being cleared to produce these agricultural commodities, contributing to climate change and social conflict.

As climate change makes precipitation shocks more common, policymakers are becoming increasingly interested in protecting food systems and nutrition outcomes from the damaging effects of droughts and floods (Wheeler and von Braun, 2013). Increasing the resilience of nutrition and food security outcomes is especially critical throughout agrarian parts of the developing world, where human subsistence and well-being are directly affected by local rainfall.

In addition to global events and food policy changes, 2015 also saw important developments with potentially wide repercussions in individual countries and regions. This chapter offers perspectives on major food policy developments across the major regions: Africa, the Middle East and North Africa, Central Asia, South Asia, East Asia, and Latin America and the Caribbean.

In addition to global developments and food policy changes, 2014 also saw important developments with potentially wide repercussions in individual countries and regions. This chapter offers perspectives on major food policy developments in various regions including Africa, the Middle East and North Africa, Central Asia, South Asia, East Asia, and Latin America and the Caribbean.

The 2013 Global Hunger Index (GHI) report-the eighth in an annual series- presents a multidimensional measure of national, regional, and global hunger. It shows that the world has made some progress in reducing hunger since 1990, but still has far to go. The 2013 GHI report focuses on resilience in theory and in practice. The relief and development communities have long struggled to understand why some people fare better than others when confronting stresses or shocks.
