| Brazil is a country with one the largest areas of forest plantations in the world. The state of Paraná (PR) has the largest area of designated plantations in the country. The main cultivated species belong to the genus Eucalyptus. In this work, the areas of better favorability for planting the main species of commercial value eucalyptus were defined. Additionally, changes may also occur in these zones in the coming decades, due to global climate change. For this purpose, future scenarios were elaborated using a stochastic time series simulation software, to assess the possible changes of the climate and indicate potential consequences regarding the changes of eucalyptus plantation zones. The results show that there will be an increase in areas favorable to... |

| The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter, arguably the number-one environment-related public health threat facing the nation. We present an integrated process model of the engineering economics of technologies to reduce methane and ammonia emissions at dairy operations in California. Three policy options are explored: greenhouse gas offset credits for methane control, particulate matter offset credits for ammonia control, and expanded net metering policies to provide revenue for the sale of electricity generated from captured methane gas. Individually, any of these policies appears to be sufficient to... |

| Brazil holds a series of favorable climatic conditions for agricultural production including the hours and intensity of sunlight, the availability of agricultural land and water resources, as well as diverse climates, soils and biomes. Amidst such diversity, Brazilian coffee producers have obtained various standards of qualities and aromas, between the arabica and robusta species, which each present a wide variety of lineages. However, temperatures in coffee producing municipalities in Brazil have increased by about 0.25 C per decade and annual precipitation has decreased. Therefore, the agricultural sector may face serious challenges in the upcoming decades due to crop sensitivity to water shortages and thermal stress. Furthermore, higher temperatures may... |

| El presente trabajo presenta un resumen de información sobre cambio climático observado en Uruguay y la región y posibles escenarios futuros. Dicha información se basa fundamentalmente en estudios conducidos y finalizados recientemente (2005-2009) en el país, en el marco del programa “Assessment of Impacts and Adaptation to Climate Change” (AIACC-START, TWAS, GEF) ( AIACC, 2006), en el “Análisis de la Estadística Climática y Desarrollo y Evaluación de Escenarios Climáticos e Hidrológicos de las principales Cuencas Hidrográficas del Uruguay y la Zona Costera” (Unidad de Cambio Climático de la DINAMA del MVOTMA de Uruguay, PNUD, GEF, 2005), en el estudio de “Identificación de Posibles Impactos del Cambio Climático en la Producción de Pasturas Naturales y de... |

| The Kyoto Protocol (1997) to the United Nations Framework Convention on Climate Change (1992) may come into force without U.S. participation, but its effects on climate change will be trivial. At the same time, the economic and scientific consensus points to the need for a credible international approach. A reasonable starting point is the Framework Convention on Climate Change (FCCC), which was signed by 161 nations and ratified by 50, including the United States, and entered into force in 1994. In this paper, I remain agnostic on the question of the Kyoto Protocol's viability. Some analysts see the agreement as deeply flawed, while others see it as an acceptable or even excellent first step. But virtually everyone agrees that the Protocol is not... |

| An RFF Workshop brought together experts from around the world to assess the feasibility of using biological sinks to sequester carbon as part of a global atmospheric mitigation effort. The chapters of this proceeding are a result of that effort. Although the intent of the workshop was not to generate a consensus, a number of studies suggest that sinks could be a relatively inexpensive and effective carbon management tool. The chapters cover a variety of aspects and topics related to the monitoring and measurement of carbon in biological systems. They tend to support the view the carbon sequestration using biological systems is technically feasible with relatively good precision and at relatively low cost. Thus carbon sinks can be operational. |

| Após a divulgação das projeções de mudanças climáticas globais pelo IPCC, a avaliação de impacto das mudanças climáticas sobre a agricultura para tornouse uma necessidade para a quantificação da vulnerabilidade dos sistemas agrícolas. Este trabalho teve como objetivo simular cenários futuros para a cana-de-açúcar no Estado de São Paulo em função de cenários regionalizados de projeções climáticas, utilizando um banco de dados de 78 estações meteorológicas com séries de, pelo menos, nove anos. Para cada estação meteorológica foi associado um determinado perfil do solo e todas as séries foram expandidas para 30 anos utilizando geradores de dados. As simulações foram feitas para a variedade RB72454, considerando dois cenários futuros de mudanças climáticas... |

| This publication aims to summarize some of the most important contributions that Embrapa has given to society on these issues. In Chapter 1, context is briefly presented, followed by problem identification in Chapter 2. Contributions to SDG 13 targets were organized in the following three chapters: Chapter 3 regarding Brazilian agriculture resilience and adaptability to risks posed by climate change; Chapter 4 discusses integrated actions to fight climate change within national plans by means of public policies. Chapter 5 deals with the contribution of the agricultural sector to mitigate GHG emissions and to adapt to climate change. Finally, in Chapter 6, a summary of the contributions of Embrapa to SDG 13 is presented and the major challenges on the... |

| The amount of carbon dioxide (CO2) of the Earth´s atmosphere is increasing, which has the potential of increasing greenhouse effect and air temperature in the future. Plants respond to environment CO2 and temperature. Therefore, climate change may affect agriculture. The purpose of this paper was to review the literature about the impact of a possible increase in atmospheric CO2 concentration and temperature on crop growth, development, and yield. Increasing CO2 concentration increases crop yield once the substrate for photosynthesis and the gradient of CO2 concentration between atmosphere and leaf increase. C3 plants will benefit more than C4 plants at elevated CO2. However, if global warming will take place, an increase in temperature may offset the... |
