O artigo aborda as respostas educativas perante as mudanças climáticas globais. Analisam-se as políticas nacionais e apresentam-se, como exemplo, resultados de pesquisa transnacional sobre mudanças climáticas e práticas educativas, da qual a Universidade de São Paulo foi parceira. O texto enfatiza que, do ponto de vista da relação entre o processo ensino-aprendizado, se observa uma enorme lacuna em termos de pesquisa, intervenção e debates em torno dos temas mais candentes. Entende-se que o maior desafio é promover um ensino baseado no aprofundamento científico sobre o tema, como, por exemplo, através da confecção de materiais didáticos interdisciplinares com conhecimentos acumulados sobre clima e mudanças globais. No Brasil, a pesquisa científica ligada às mudanças climáticas está adquirindo gradualmente uma posição estratégica nos programas de ciência e tecnologia, revelando uma combinação original entre educação e conhecimento científico. A questão mais desafiadora é criar condições para que as iniciativas educacionais sejam estratégicas para realizar as mudanças necessárias para motivar os cidadãos a agir em direção às metas de sustentabilidade, dada a existência de barreiras estruturais e institucionais relativas à mudança rumo a uma sociedade mais sustentável.; The text presents the response from education facing global climate changes. It analyses the national policies and introduces as an example...

Este trabalho investiga a variabilidade do Sistema de Monções da América do Sul (SMAS) sobre o Brasil com particular interesse na região do cerrado brasileiro. O início, final e total de precipitação durante as monções de verão são examinados utilizando estimativas de precipitação por satélite (pêntadas) do Global Precipitation Climatology Project (GPCP) entre 1979-2004. Analogamente, as características do regime de monção simuladas pelo modelo climático global acoplado MIROC (Model for interdisciplinary Research on Climate) do IPCC (Intergovernmental Panel for Climate Change) são examinadas em dois cenários distintos: o clima do século XX (1981-2000) e o clima em uma condição com o dobro da concentração atual de CO2 (2xCO2) na atmosfera (2061-2080). Mostra-se que a variabilidade espacial do início da monção de verão sobre o cerrado na simulação do clima do século XX pelo MIROC corresponde bem às observações. Além disso, há indicação de uma mudança das caudas da distribuição sazonal da precipitação no Cerrado para um cenário com 2xCO2, comparativamente com o clima presente. Este resultado sugere uma mudança na probabilidade de ocorrência de eventos extremos (secos ou úmidos) em um cenário com 2xCO2 sobre o cerrado...

Estudos recentes mostram que as concentrações de gases de efeito estufa na atmosfera vêm aumentando desde a Revolução Industrial. A esse acréscimo de gases, originado principalmente por atividades antrópicas, como a queima de combustíveis fósseis e o desmatamento, atribui-se a responsabilidade principal pelo aquecimento global. Além da temperatura, a precipitação também tem sofrido variações decorrentes dessas práticas e as projeções climáticas para este século indicam a possibilidade de graves conseqüências para a humanidade. Dentre as atividades econômicas, a agricultura é a mais dependente dos fatores climáticos e as alterações desses fatores afetarão a produtividade das culturas, com efeito sobre o agronegócio como um todo. No presente trabalho, foi utilizado um modelo agrometeorológico para estimar a produtividade da cana-de-açúcar na região de Piracicaba, SP, e, com base nos cenários futuros apresentados no quarto relatório do Painel Intergovernamental sobre Mudanças Climáticas (IPCC), foram avaliados os possíveis impactos que alterações de temperatura, precipitação, insolação e concentração de CO2 na atmosfera poderão causar na produtividade dessa cultura, levando em conta também os avanços tecnológicos. Utilizando-se os cenários de mudanças climáticas adotados para a execução deste estudo...

Rust, caused by Puccinia psidii, is one of the most important diseases affecting eucalyptus in Brazil. This pathogen causes disease in mini-clonal garden and in young plants in the field, especially in leaves and juvenile shoots. Favorable climate conditions for infection by this pathogen in eucalyptus include temperature between 18 and 25 ºC, together with at least 6-hour leaf wetness periods, for 5 to 7 consecutive days. Considering the interaction between the environment and the pathogen, this study aimed to evaluate the potential impact of global climate changes on the spatial distribution of areas of risk for the occurrence of eucalyptus rust in Brazil. Thus, monthly maps of the areas of risk for the occurrence of this disease were elaborated, considering the current climate conditions, based on a historic series between 1961 and 1990, and the future scenarios A2 and B2, predicted by IPCC. The climate conditions were classified into three categories, according to the potential risk for the disease occurrence, considering temperature (T) and air relative humidity (RH): i) high risk (18 < T < 25 ºC and RH > 90%); ii) medium risk (18 < T < 25 ºC and RH < 90%; T< 18 or T > 25 ºC and RH > 90%); and iii) low risk (T < 18 or T > 25 ºC and RH < 90%). Data about the future climate scenarios were supplied by GCM Change Fields. In this study...

In this paper, we analyze the daily number of hospitalizations in São Paulo City, Brazil, in the period of January 01, 2002 to December 31, 2005. This data set relates to pneumonia, coronary ischemic diseases, diabetes and chronic diseases in different age categories. In order to verify the effect of climate changes the following covariates are considered: atmosphere pressure, air humidity, temperature, year season and also a covariate related to the week day when the hospitalization occurred. The possible effects of the assumed covariates in the number of hospitalization are studied using a Poisson regression model in the presence or not of a random effect which captures the possible correlation among the hospitalization accounting for the different age categories in the same day and the extra-Poisson variability for the longitudinal data. The inferences of interest are obtained using the Bayesian paradigm and MCMC (Markov chain Monte Carlo) methods.

Climate changes, at global and local levels, are associated not only natural atmospheric effects, but also to anthropogenic changes, with the release of CO2 into the lower layer of the atmosphere. The impacts of climate changes can be objects of study in hydrology through the use of mathematical models, rainfall output, with the hydro-climatic input data. Hydrological model in Geographic Information System - SIG, used in hydrologic studies of watersheds to predict and measure the system response to external conditions and interest of a watershed. The integration of SIG with hydrological information gave the possibility to obtain distributed information with a response of flow in watershed in different locations has been explored in distributed hydrological modeling. The objective of this study was to evaluate the MGB-IPH model (Modelo de Grandes Bacias) watershed in Paraíba do Meio River, influence of climate change predicted on Climate Change Panel - IPCC. The hydrological model for large basin, MGB / IPH was applied in the Paraíba do Meio river watershed and was calibrated manually. Simulations were conducted for the current scenario, and scenarios A1B and A2, on Climate Change Panel (IPCC), for the years 2071 to 2100, predicted to Brazil by CPTEC / INPE...

Climate models generally indicate that climate volatility may rise in the future, severely affecting agricultural productivity through greater frequency of yield-diminishing climate extremes, such as droughts. For Tanzania, where agricultural production is sensitive to climate, changes in climate volatility could have significant implications for poverty. This study assesses the vulnerability of Tanzania s population to poverty to changes in climate variability between the late 20th century and early this century. Future climate scenarios with the largest increases in climate volatility are projected to make Tanzanians increasingly vulnerable to poverty through its impacts on the production of staple grains, with as many as 90,000 additional people, representing 0.26 percent of the population, entering poverty in the median case. Extreme poverty-increasing outcomes are also found to be greater in the future under certain climate scenarios. In the 20th century, the greatest predicted increase in poverty was equal to 880...

Several studies addressing the supply and demand for food in China suggest that the nation can largely meet its needs in the coming decades. However, these studies do not consider the effects of climate change. This paper examines whether near future expected changes in climate are likely to alter this picture. The authors analyze the effect of temperature and precipitation on net crop revenues using a cross section consisting of both rainfed and irrigated farms. Based on survey data from 8,405 households across 28 provinces, the results of the Ricardian analysis demonstrate that global warming is likely to be harmful to China but the impacts are likely to be very different in each region. The mid latitude region of China may benefit from warming but the southern and northern regions are likely to be damaged by warming. More precipitation is beneficial to Chinese farmers except in the wet southeast. Irrigated and rainfed farmers have similar responses to precipitation but not to temperature. Warmer temperatures may benefit irrigated farms but they are likely to harm rainfed farms. Finally...

The authors use a Ricardian model to test the relationship between annual net revenues and climate across Israeli farms. They find that it is important to include the amount of irrigation water available to each farm in order to measure the response of farms to climate. With irrigation water omitted, the model predicts that climate change is strictly beneficial. But with water included, the model predicts that only modest climate changes are beneficial, while drastic climate change in the long run will be harmful. Using the Atmospheric Oceanic Global Circulation Models scenarios, the authors show that farm net revenue is expected to increase by 16 percent in 2020, while in 2100 farm net revenue is expected to drop by 60-390 percent varying between the different scenarios. Although Israel has a relatively warm climate, a mild increase in temperature is beneficial due to the ability to supply international markets with farm products early in the season. The findings lead to the conclusion that securing water rights to the farmers and international trade agreements can be important policy measures to help farmers adapt to climate change.

This study examines the impact of climate change on cropland in Africa. It is based on a survey of more than 9,000 farmers in 11 countries: Burkina Faso, Cameroon, Egypt, Ethiopia, Ghana, Kenya, Niger, Senegal, South Africa, Zambia, and Zimbabwe. The study uses a Ricardian cross-sectional approach in which net revenue is regressed on climate, water flow, soil, and economic variables. The results show that net revenues fall as precipitation falls or as temperatures warm across all the surveyed farms. In addition to examining all farms together, the study examined dryland and irrigated farms separately. Dryland farms are especially climate sensitive. Irrigated farms have a positive immediate response to warming because they are located in relatively cool parts of Africa. The study also examined some simple climate scenarios to see how Africa would respond to climate change. These uniform scenarios assume that only one aspect of climate changes and the change is uniform across all of Africa. In addition, the study examined three climate change scenarios from Atmospheric Oceanic General Circulation Models. These scenarios predicted changes in climate in each country over time. Not all countries are equally vulnerable to climate change. First...

Scientists are confident of a link between greenhouse gas emissions, the increasing concentration of those gases in the atmosphere, and climate change. However, the final impacts from climate change are difficult to estimate, since we have no direct experience with new climates. Past climate change has been small and slow, making the impacts hard to discern. Further, technological changes have obscured signals from historic climate changes. Despite these difficulties, the impact literature has made many strides toward understanding and quantifying climatic impacts.

This paper uses municipality level data to estimate the general relationship between climate, income, and life expectancy in Chile. The analysis finds that incomes are negatively related to temperature, while life expectancy is not significantly related to average temperatures. Both incomes and life expectancy are greater in areas with either very little rain or a lot of rain. The authors use the estimated relationships to simulate the effects of both past (1958-08) and future (2008-58) climate change. The findings indicate that past climate change has been favorable for the central, and most populous, part of Chile, and it has contributed to reduced poverty and reduced inequality of health outcomes. Whereas temperatures in the past have shown a downward trend for most of the Chilean population, climate models suggest that they will increase in the future, and that there will be a reduction in precipitation in the central part of Chile. The analysis simulates the likely effects of these projected climate changes over the next 50 years. The findings suggest that expected future climate will tend to reduce incomes across the whole country...

This paper uses quantitative methods to examine the way African farmers have adapted livestock management to the range of climates found across the African continent. The authors use logit analysis to estimate whether farmers adopt livestock. They then use three econometric models to examine which species farmers choose: a primary choice multinomial logit, an optimal portfolio multinomial logit, and a demand system multivariate probit. Comparing the results of the three methods of estimating species selection reveals that the three approaches yield similar results. Using data from over 9,000 African livestock farmers in 10 countries, the analysis finds that farmers are more likely to choose to have livestock as temperatures increase and as precipitation decreases. Across all methods of estimating choice, livestock farmers in warmer locations are less likely to choose beef cattle and chickens and more likely to choose goats and sheep. As precipitation increases, cattle and sheep decrease but goats and chickens increase. The authors simulate the way farmers' choices might change with a set of uniform climate changes and a set of climate model scenarios. The uniform scenarios predict that warming and drying would increase livestock ownership but that increases in precipitation would decrease it. The climate scenarios predict a decrease in the probability of beef cattle and an increase in the probability of sheep and goats...

This study examines the impact of climate change on crop farming in Cameroon. The country's economy is predominantly agrarian and agriculture and the exploitation of natural resources remain the driving force for the country's economic development. Fluctuations in national income are due not merely to the decline in world demand for Cameroon's traditional agricultural exports or to mistakes in economic policy making, but also to the vagaries of the weather. Based on a farm-level survey of more than 800 farms, the study employs a Ricardian cross-sectional approach to measure the relationship between climate and the net revenue from crops. Net revenue is regressed on climate, water flow, soil, and economic variables. Further, uniform scenarios assume that only one aspect of climate changes and the change is uniform across the whole country. The analysis finds that net revenues fall as precipitation decreases or temperatures increase across all the surveyed farms. The study reaffirms that agriculture in Cameroon is often limited by seasonality and the availability of moisture. Although other physical factors...

In countries such as Georgia, the risks of climate change for the agricultural sector are a particularly immediate and important problem because the majority of the rural population depends either directly or indirectly on agriculture for their livelihoods. The most effective plans for adapting the sector to climate change will involve both human capital and physical capital enhancements; however, many of these investments can also enhance agricultural productivity right now, under current climate conditions. Recommendations, such as improving the accessibility to farmers of agriculturally relevant weather forecasts, will yield benefits as soon as they are implemented and provide a means for farmers to autonomously adapt their practices as climate changes. In response to these challenges, the World Bank and the Government of Georgia embarked on a joint study to identify and prioritize options for climate change adaptation of the agricultural sector, with explicit consideration of greenhouse gas emission reduction potential of these options. The study was conducted in three stages: awareness raising; quantitative and qualitative analysis; and finalization of the analysis and menu of adaptation options. This report provides a menu of options for climate change adaptation in the agricultural and water resources sectors...

This paper uses a cross sectional method to analyze irrigation choice and crop choice across 8,405 farmers in 28 provinces in China. The findings show that Chinese farmers are more likely to irrigate when facing lower temperatures and less precipitation. Farmers in warmer places are more likely to choose oil crops, maize, and especially cotton and wheat, and are less likely to choose vegetables, potatoes, sugar, and especially rice and soybeans. In wetter locations, farmers are more likely to choose soybeans, oil crops, sugar, vegetables, cotton, and especially rice, and they are less likely to choose potatoes, wheat, and especially maize. The analysis of how Chinese farmers have adapted to current climate, provides insight into how they will likely adapt when climate changes. Future climate scenarios will cause farmers in China to want to reduce irrigation and shift toward oil crops, wheat, and especially cotton. In turn, farmers will shift away from potatoes, rice, vegetables, and soybeans. However...

As mudanças climáticas vêm sendo estudadas principalmente pelas ciências exatas e da natureza. Buscaremos nesse trabalho agregar o ponto de vista da antropologia ao estudos sobre o assunto. Nossa pergunta é: Como os povos da região do alto Juruá observam e vivem as mudanças climáticas? Eventos climáticos extremos, como chuvas inesperadas e grandes alagações ou inundações, fazem parte das memória desses moradores da floresta. Essas memórias são transmitidas por gerações. Assim, as histórias de inundação que se destacam no alto Juruá ainda permanecem vivas. O clima é muito importante para as pessoas que vivem na floresta, sendo um saber que está relacionado às necessidades práticas do mundo da vida. Para dar conta desse saber, coletamos observações de ex-seringueiros e agricultores, dos Huni Kuin e dos Ashaninka sobre o clima e suas variações, sobre estações e previsões. Com isso, obtivemos uma visão sobre diferentes olhares, dentro das respectivas visões de mundo, sobre as transformações climáticas. Esses grupos, ao longo de gerações, desenvolveram conhecimentos sobre o ambiente e sobre o clima. Entendemos que é parte do papel da Antropologia mostrar esses conhecimentos, visibilizando os saberes tradicionais sobre a natureza. Essa tarefa é hoje importante...

Climate changes impact biodiversity, which can influence the adaptation to that fact by the use of genetic resources in the development of new more resistant to global warming vegetable varieties, which can be judicially for the countries based on the intellectual property as a patent or by the right to protection to vegetable varieties. For this reason, international agreements about biodiversity (CDB), global warming (CQMC), desertification (CNUCD) and access to python genetic resources (TIRFAA) and international agreements about intellectual property are interrelated, what has created an articulation process among these agreements. The conclusion is that some amendments in their texts are required in order to give effectiveness to this articulation process and positive for the adaptation to the climate change and relieve of their effects.; A mudança do clima impacta a biodiversidade e esta, por sua vez, pode contribuir para a adaptação a este fenômeno pelo uso dos recursos genéticos para o desenvolvimento de novas variedades vegetais mais resistentes ao aquecimento global, as quais podem ser protegidas judicialmente nos diversos países pelo direito de propriedade intelectual na modalidade direito de patente ou na modalidade direito de proteção à variedade vegetal.
