This paper examines climate change impacts on South American agricultureusing a set of Ricardian regressions estimated across different samples of farms in SouthAmerica. Regressions are run for the whole sample and for subsamples of crop-only,mixed, and livestock-only farms. The results indicate that climate sensitivity varies agreat deal across each type of farm. The analysis also reveals that the impacts will varysubstantially across South America. The hot and wet Amazon and Equatorial regionsare likely to lose the most from warming scenarios whereas the more temperate highelevation and southern regions of South America will likely gain.

<p>After several coups assisted by US agencies since the fifties in Latin America, and deep economic crises in the eighties and the nineties in South America explained by “the rule of markets” enforced by multilateral organizations, the US leadership in the Americas has been lost, and democratic countries have turned against neoliberalism with wide popular support inside a new “South American revolution” with important projects of integration. Colombia has become the capital in South America for US leadership in economics and politics, and the only country that still has guerrillas, paramilitary armies, and internal conflict. What has been the role of the US in Colombian conflict? What is in stake with the new peace process in Colombia? How this process will affect the US leadership in Latin America? These are some questions that will be reviewed by Noam Chomsky, one of the most influential thinkers of our times.</p>

The late-Holocene expansion of the Tupi–Guarani languages from southern Amazonia to SE South America constitutes one of the largest expansions of any linguistic family in the world, spanning ~4000 km between latitudes 0°S and 35°S at about 2.5k cal. yr BP. However, the underlying reasons for this expansion are a matter of debate. Here, we compare continental-scale palaeoecological, palaeoclimate and archaeological datasets, to examine the role of climate change in facilitating the expansion of this forest-farming culture. Because this expansion lies within the path of the South American Low-Level Jet, the key mechanism for moisture transport across lowland South America, we were able to explore the relationship between climate change, forest expansion and the Tupi–Guarani. Our data synthesis shows broad synchrony between late-Holocene increasing precipitation and southerly expansion of both tropical forest and Guarani archaeological sites – the southernmost branch of the Tupi–Guarani. We conclude that climate change likely facilitated the agricultural expansion of the Guarani forest-farming culture by increasing the area of forested landscape that they could exploit, showing a prime example of ecological opportunism.

In this paper, we assess the economy-wide impact of Climate Change (CC) on agriculture and food security in 20 Latin American and the Caribbean (LAC) countries. Specifically, we focus on the following three channels through which CC may affect agricultural and non-agricultural production: (i) agricultural yields; (ii) labor productivity in agriculture, and; (iii) economy-wide labor productivity. We implement the analysis using the Integrated Economic-Environmental Model (IEEM) and databases for 20 LAC available through the OPEN IEEM Platform. Our analysis identifies those countries most affected according to key indicators including Gross Domestic Product (GDP), international commerce, sectoral output, poverty, and emissions. Most countries experience negative impacts on GDP, with the exception of the major soybean producing countries, namely, Brazil, Argentina and Uruguay. We find that CC-induced crop productivity and labor productivity changes affect countries differently. The combined impact, however, indicates that Belize, Nicaragua, Guatemala and Paraguay would fare the worst. Early identification of these hardest hit countries can enable policy makers pre-empting these effects and beginning the design of adaptation strategies early on. In terms of greenhouse gas emissions, only Argentina, Chile and Uruguay would experience small increases in emissions.

This chapter explains the role of human activities in driving climate change, and some of its most significant impacts. It discusses justice issues raised by climate change, including causal responsibility, future development rights, the distribution of climate change harms, and intergenerational inequity. The chapter also provides a status update on current health inequities, noting the now recognized role of political, economic, commercial, and social factors in determining health. This section also discusses environmental epidemiology and the shift to eco-social approaches and eco-epidemiology, noting that while eco-epidemiologists have begun to research the influence of climate change on health, this research has not yet considered in depth the influence of social systems. The chapter concludes with an overview of how climate change exacerbates existing health inequities, focusing on the health implications of significant climate change impacts, including extreme weather events, rising sea levels, heat stress, vector-borne diseases, and food insecurity.
