    http://www.dsr.inpe.br/sbsr2011/files/p0665.pdf; International audience; In recent years, several works have been accomplished in order to analyze the spectral response of coffee crop fields cultivated in full sun. However, the number of papers related to the monitoring of shaded coffee systems is reduced although this kind of cultivation is very important from the perspective of climate change and agriculture. In addition, the biomass of coffee systems can store carbon, which is a mitigation action. In this context, this paper presents the assessment of the meteorological variation joined with the biomass increase in three different coffee plantation systems: full sun, shaded coffee associated with legumes (SAF), and shaded coffee with Macadamia trees. We used Landsat-5 images from 2004 to 2010, and the NDVI and SAVI indexes. LAI index measured in the test area during all 2009 year. The results showed that the shaded coffee systems presented the NDVI and SAVI indexes with higher values than those found with the system of planting in full sun what corroborates the idea of greater amount of biomass in this type of planting. All indexes present the seasonal rain variation. One month after a large period of drought the indexes NDVI, SAVI and LAI decrease. The NDVI and SAVI indexes presented high correlation with the measured LAI. The shaded coffee system and the full sun coffee reached high vegetation indexes what indicate a high concentration of biomass. This factor should be considered in the decision making process since is important to take advantage of cultivation systems acting as carbon sinks.

    National audience ABSTRACT. Great droughts of the past (such as 1959, 1976, 1989 or 2003) have had heavy impacts on important socio-economical activities for the economy of the Brittany, such as agriculture. In a climate change context it seems important to evaluate the possible ways of evolution of that risk in this region. These evolutions have been studied by using climate simulations from three IPCC’s scenarios: A1B, A2 and B1. In order to monitor droughts, the methodology used is a soil water balance and the implementation of the evaporation deficit. Results revealed an increase of drought intensity during the 21st century, more specifically in the eastern part of the region. The south coastline would be the most sensitive area in terms of droughts’ intensity and frequency. In that area a similar intensity as the one measured during the 1976 drought, other things being equal, would be frequently reached. Exceptional past droughts could become common in the future, impacting both agriculture and water cycle. This could cause a decreasing in runoff aquifer's levels and force farmers to adapt both crops and cropping methods. RESUME. Les grandes sécheresses du passé (1959, 1976, 1989 ou 2003) ont entrainé des dommages importants sur des activités essentielles pour l’économie de la Bretagne, telles que l’agriculture. Dans un contexte de changement climatique, il apparait donc important d'analyser les évolutions possibles du risque de sécheresse à l’échelle de la région à partir de simulations climatiques du modèle Arpège-Climat pour trois scénarios du GIEC : A1B, A2 et B1. La méthodologie retenue est celle du bilan hydrique et le calcul du déficit d’évaporation. Les résultats montrent une augmentation de l’intensité des sécheresses au cours du 21ème siècle, principalement pour la moitié est de la Bretagne. Le littoral sud serait la région la plus sensible à une augmentation de la fréquence et de l’intensité des sécheresses. En termes d’intensité, on dépasserait ici les valeurs relevées lors de la sécheresse de 1976, toutes choses égales par ailleurs. Ce risque de voir des sécheresses exceptionnelles par le passé devenir communes à moyen terme, impacterait fortement l’agriculture, ainsi que le cycle de l’eau, sur une grande partie de l’année. Cela pourrait entrainer une diminution des écoulements de surface alimentant les nappes phréatiques bretonnes et contraindre les agriculteurs à adapter leurs cultures et leurs pratiques. RESUMO. As grandes secas do passado (1959, 1976, 1989 ou 2003) resultaram em danos significativos às atividades essenciais para a economia da Bretanha, como a agricultura. Por isso, no contexto das mudanças climáticas, parece importante analisar possíveis mudanças quanto ao o risco de seca na escala regional. Essas mudanças são estudadas por meio de simulações climáticas do modelo Arpège-Clima para três cenários do IPCC: A1B, A2 e B1. Para monitorar as secas, a metodologia utilizada é o balanço hídrico e o cálculo do déficit de evaporação. Os resultados mostram um aumento na intensidade das secas durante o século 21, principalmente para a metade oriental da Bretanha. A costa sul seria a região mais sensível para o aumento e a frequência da intensidade das secas. Em termos de intensidade, seriam ultrapassados os valores registrados durante a seca histórica de 1976, inalteradas as circunstâncias. O risco de seca excepcional no passado tornou-se comum em médio prazo e teria um impacto forte sobre a agricultura e o ciclo da água durante uma grande parte do ano. Isso pode causar uma diminuição no escoamento que alimenta o lençol freático na Bretanha e forçar os agricultores a adaptar as suas culturas e práticas agricolas.

    No marco do Programa SERVIR-Amazonia, uma iniciativa da Administração Nacional de Aeronáutica e Espaço dos Estados Unidos (NASA) e da Agência dos Estados Unidos para o Desenvolvimento Internacional (USAID), se organizou a oficina de trabalho: “Consulta sobre as Necessidades dos Usuários do Programa SERVIR-Amazonia” Brasília-DF, nos dias 23 e 24 de outubro de 2019. O principal objetivo da oficina, a qual contou com a participação de 71 representantes de 36 organizações, foi o de obter uma aproximação primária, desde a perspectiva dos atores envolvidos, sobre os principais problemas/ameaças que afetam a Amazônia emolduradas nas 4 áreas temáticas trabalhadas pelo Programa. Com base nesta informação, e através de um processo participativo de dois dias, identificaram-se as necessidades de informação e as oportunidades para as melhores decisões que permitam priorizar o co-desenho de serviços. Durante a oficina, uma discussão inicial foi facilitada sobre as percepções dos participantes quanto ao estado atual da tomada de decisão ambiental com base em informações geoespaciais no Brasil. O mapeamento dos serviços existentes e dos principais atores foi realizado de forma participativa e orientado pelas áreas temáticas. Esse mapeamento é o principal elemento para a priorização dos serviços a serem desenvolvidos durante o Programa e será usado na fase de definição e desenvolvimento do mesmo. Este exercício mostrou que já existem muitas informações, atores e serviços existentes. Além disso, 5 principais categorias de necessidades foram identificadas com relação à melhoria do uso de informações geoespaciais no Brasil: integração de banco de dados e informação; aprimoramento de tecnologias de monitoramento; articulação de atores institucionais; padronização da informação; e capacitação e treinamento.

    Mozambique is considered one of the countries that will suffer significant negative effects of climate change, in particular droughts, floods and cyclones. The district of Chicualacuala, due to its geographical location, in an area with semi-arid characteristics, will suffer the consequences of cyclical droughts and floods, high temperatures and desertification. The population will be negatively affected by these phenomena, as their survival is dependent on farming and the exploitation of natural resources. On top of these factors, there is weak development of infrastructure and social services in the district. The main effects of climate change include: the reduction of agricultural productivity, loss of crops, decrease in the availability of pasture, reduction in the availability of water, higher incidences of disease and death of livestock, and land degradation. This could, therefore, lead to the reduction of household income, increased food and nutritional insecurity, and the increase in the number of cases of diseases such as malaria, cholera and diarrhea in this population.

    Authors: Dubos-Raoul, Marine;

    International audience The sugar-energy industry sector, responsible for the production of sugar cane and its transformation in ethanol and/or electric energy, has been known since the beginning of the XXI century a new expanded phase based in the real terms of the sustainable development. The aim of this article was to analyse in the contemporary period in what way the public politics, national and international ones, together with the agri-business sugar-energy industry and local actors borrowed the speech of sustainability. We also intended to understand how the measures from this new paradigm concluded to justify the expansion of the sugar-energy industry sector. The methodology is based on the bibliography research, in the farming data surveys as well as in the analysis of developing programs and finally in the camping research. The work highlight that the assumption of the sustainable development speech became strategy to the maintenance and expansion of the sugar-energy sector, showing its action in favor of the environment. However, it was seen that the actors admit contradictions existing between the principles of conservation of the environment and the reality of the actors from the sustainability speech El sector sucroenergético, responsable por la producción de caña de azúcar y su transformación en azúcar, alcohol y/o energía eléctrica, ha encontrado desde inicios del siglo XXI una nueva forma de expansión basada en los términos actuales del desarrollo sostenible. El objetivo de este artículo fue analizar en el periodo contemporáneo, de qué modo las políticas públicas nacionales e internacionales, aliadas a las agroindustrias sucroenergéticas y actores locales, se apropiaron del discurso de la sostenibilidad. Así como comprender cómo las medidas derivadas de este nuevo paradigma terminaron por justificar la expansión del sector sucroenergético. La metodología aplicada fue basada en la revisión bibliográfica, colecta de datos agropecuarios, también como en investigaciones de campo. Fue posible evidenciar que la apropiación del discurso sobre desarrollo sostenible se volvió estratégico a fin de mantener y expandir el sector sucroenergético, exponiendo sus acciones a favor del medio ambiente. Aún así, se pudo verificar el reconocimiento por parte de los actores, sobre las contradicciones existentes entre los principios de la conservación del medio ambiente y la realidad de las acciones que derivan del discurso sobre la sustentabilidad. O setor sucroenergético, responsável pela produção de cana-de-açúcar e sua transformação em açúcar, álcool e/ou energia elétrica, conhece desde o início do século XXI uma nova fase de expansão baseada nos termos atuais do desenvolvimento sustentável. O presente artigo objetiva analisar no período contemporâneo o modo como as políticas públicas nacionais e internacionais, juntamente com o agronegócio sucroenergético e os atores locais, apropriaram-se do discurso da sustentabilidade, bem como compreender como as medidas decorrentes desse novo paradigma findaram em justificar a expansão do setor sucroenergético. A metodologia é baseada na pesquisa bibliográfica, no levantamento de dados agropecuários, assim como na análise de programas de desenvolvimento e, por fim, em pesquisas de campo. O trabalho evidencia que a apropriação do discurso do desenvolvimento sustentável se tornou estratégico para a manutenção e expansão do setor sucroenergético, expoente as suas ações em favor do meio ambiente. Contudo, foi verificado que os atores admitem as contradições existentes entre os princípios da conservação do meio ambiente e a realidade dos atos decorrente do discurso da sustentabilidade.

    http://www.dsr.inpe.br/sbsr2011/files/p0665.pdf; International audience; In recent years, several works have been accomplished in order to analyze the spectral response of coffee crop fields cultivated in full sun. However, the number of papers related to the monitoring of shaded coffee systems is reduced although this kind of cultivation is very important from the perspective of climate change and agriculture. In addition, the biomass of coffee systems can store carbon, which is a mitigation action. In this context, this paper presents the assessment of the meteorological variation joined with the biomass increase in three different coffee plantation systems: full sun, shaded coffee associated with legumes (SAF), and shaded coffee with Macadamia trees. We used Landsat-5 images from 2004 to 2010, and the NDVI and SAVI indexes. LAI index measured in the test area during all 2009 year. The results showed that the shaded coffee systems presented the NDVI and SAVI indexes with higher values than those found with the system of planting in full sun what corroborates the idea of greater amount of biomass in this type of planting. All indexes present the seasonal rain variation. One month after a large period of drought the indexes NDVI, SAVI and LAI decrease. The NDVI and SAVI indexes presented high correlation with the measured LAI. The shaded coffee system and the full sun coffee reached high vegetation indexes what indicate a high concentration of biomass. This factor should be considered in the decision making process since is important to take advantage of cultivation systems acting as carbon sinks.

    National audience ABSTRACT. Great droughts of the past (such as 1959, 1976, 1989 or 2003) have had heavy impacts on important socio-economical activities for the economy of the Brittany, such as agriculture. In a climate change context it seems important to evaluate the possible ways of evolution of that risk in this region. These evolutions have been studied by using climate simulations from three IPCC’s scenarios: A1B, A2 and B1. In order to monitor droughts, the methodology used is a soil water balance and the implementation of the evaporation deficit. Results revealed an increase of drought intensity during the 21st century, more specifically in the eastern part of the region. The south coastline would be the most sensitive area in terms of droughts’ intensity and frequency. In that area a similar intensity as the one measured during the 1976 drought, other things being equal, would be frequently reached. Exceptional past droughts could become common in the future, impacting both agriculture and water cycle. This could cause a decreasing in runoff aquifer's levels and force farmers to adapt both crops and cropping methods. RESUME. Les grandes sécheresses du passé (1959, 1976, 1989 ou 2003) ont entrainé des dommages importants sur des activités essentielles pour l’économie de la Bretagne, telles que l’agriculture. Dans un contexte de changement climatique, il apparait donc important d'analyser les évolutions possibles du risque de sécheresse à l’échelle de la région à partir de simulations climatiques du modèle Arpège-Climat pour trois scénarios du GIEC : A1B, A2 et B1. La méthodologie retenue est celle du bilan hydrique et le calcul du déficit d’évaporation. Les résultats montrent une augmentation de l’intensité des sécheresses au cours du 21ème siècle, principalement pour la moitié est de la Bretagne. Le littoral sud serait la région la plus sensible à une augmentation de la fréquence et de l’intensité des sécheresses. En termes d’intensité, on dépasserait ici les valeurs relevées lors de la sécheresse de 1976, toutes choses égales par ailleurs. Ce risque de voir des sécheresses exceptionnelles par le passé devenir communes à moyen terme, impacterait fortement l’agriculture, ainsi que le cycle de l’eau, sur une grande partie de l’année. Cela pourrait entrainer une diminution des écoulements de surface alimentant les nappes phréatiques bretonnes et contraindre les agriculteurs à adapter leurs cultures et leurs pratiques. RESUMO. As grandes secas do passado (1959, 1976, 1989 ou 2003) resultaram em danos significativos às atividades essenciais para a economia da Bretanha, como a agricultura. Por isso, no contexto das mudanças climáticas, parece importante analisar possíveis mudanças quanto ao o risco de seca na escala regional. Essas mudanças são estudadas por meio de simulações climáticas do modelo Arpège-Clima para três cenários do IPCC: A1B, A2 e B1. Para monitorar as secas, a metodologia utilizada é o balanço hídrico e o cálculo do déficit de evaporação. Os resultados mostram um aumento na intensidade das secas durante o século 21, principalmente para a metade oriental da Bretanha. A costa sul seria a região mais sensível para o aumento e a frequência da intensidade das secas. Em termos de intensidade, seriam ultrapassados os valores registrados durante a seca histórica de 1976, inalteradas as circunstâncias. O risco de seca excepcional no passado tornou-se comum em médio prazo e teria um impacto forte sobre a agricultura e o ciclo da água durante uma grande parte do ano. Isso pode causar uma diminuição no escoamento que alimenta o lençol freático na Bretanha e forçar os agricultores a adaptar as suas culturas e práticas agricolas.

    No marco do Programa SERVIR-Amazonia, uma iniciativa da Administração Nacional de Aeronáutica e Espaço dos Estados Unidos (NASA) e da Agência dos Estados Unidos para o Desenvolvimento Internacional (USAID), se organizou a oficina de trabalho: “Consulta sobre as Necessidades dos Usuários do Programa SERVIR-Amazonia” Brasília-DF, nos dias 23 e 24 de outubro de 2019. O principal objetivo da oficina, a qual contou com a participação de 71 representantes de 36 organizações, foi o de obter uma aproximação primária, desde a perspectiva dos atores envolvidos, sobre os principais problemas/ameaças que afetam a Amazônia emolduradas nas 4 áreas temáticas trabalhadas pelo Programa. Com base nesta informação, e através de um processo participativo de dois dias, identificaram-se as necessidades de informação e as oportunidades para as melhores decisões que permitam priorizar o co-desenho de serviços. Durante a oficina, uma discussão inicial foi facilitada sobre as percepções dos participantes quanto ao estado atual da tomada de decisão ambiental com base em informações geoespaciais no Brasil. O mapeamento dos serviços existentes e dos principais atores foi realizado de forma participativa e orientado pelas áreas temáticas. Esse mapeamento é o principal elemento para a priorização dos serviços a serem desenvolvidos durante o Programa e será usado na fase de definição e desenvolvimento do mesmo. Este exercício mostrou que já existem muitas informações, atores e serviços existentes. Além disso, 5 principais categorias de necessidades foram identificadas com relação à melhoria do uso de informações geoespaciais no Brasil: integração de banco de dados e informação; aprimoramento de tecnologias de monitoramento; articulação de atores institucionais; padronização da informação; e capacitação e treinamento.

    Mozambique is considered one of the countries that will suffer significant negative effects of climate change, in particular droughts, floods and cyclones. The district of Chicualacuala, due to its geographical location, in an area with semi-arid characteristics, will suffer the consequences of cyclical droughts and floods, high temperatures and desertification. The population will be negatively affected by these phenomena, as their survival is dependent on farming and the exploitation of natural resources. On top of these factors, there is weak development of infrastructure and social services in the district. The main effects of climate change include: the reduction of agricultural productivity, loss of crops, decrease in the availability of pasture, reduction in the availability of water, higher incidences of disease and death of livestock, and land degradation. This could, therefore, lead to the reduction of household income, increased food and nutritional insecurity, and the increase in the number of cases of diseases such as malaria, cholera and diarrhea in this population.

    International audience The sugar-energy industry sector, responsible for the production of sugar cane and its transformation in ethanol and/or electric energy, has been known since the beginning of the XXI century a new expanded phase based in the real terms of the sustainable development. The aim of this article was to analyse in the contemporary period in what way the public politics, national and international ones, together with the agri-business sugar-energy industry and local actors borrowed the speech of sustainability. We also intended to understand how the measures from this new paradigm concluded to justify the expansion of the sugar-energy industry sector. The methodology is based on the bibliography research, in the farming data surveys as well as in the analysis of developing programs and finally in the camping research. The work highlight that the assumption of the sustainable development speech became strategy to the maintenance and expansion of the sugar-energy sector, showing its action in favor of the environment. However, it was seen that the actors admit contradictions existing between the principles of conservation of the environment and the reality of the actors from the sustainability speech El sector sucroenergético, responsable por la producción de caña de azúcar y su transformación en azúcar, alcohol y/o energía eléctrica, ha encontrado desde inicios del siglo XXI una nueva forma de expansión basada en los términos actuales del desarrollo sostenible. El objetivo de este artículo fue analizar en el periodo contemporáneo, de qué modo las políticas públicas nacionales e internacionales, aliadas a las agroindustrias sucroenergéticas y actores locales, se apropiaron del discurso de la sostenibilidad. Así como comprender cómo las medidas derivadas de este nuevo paradigma terminaron por justificar la expansión del sector sucroenergético. La metodología aplicada fue basada en la revisión bibliográfica, colecta de datos agropecuarios, también como en investigaciones de campo. Fue posible evidenciar que la apropiación del discurso sobre desarrollo sostenible se volvió estratégico a fin de mantener y expandir el sector sucroenergético, exponiendo sus acciones a favor del medio ambiente. Aún así, se pudo verificar el reconocimiento por parte de los actores, sobre las contradicciones existentes entre los principios de la conservación del medio ambiente y la realidad de las acciones que derivan del discurso sobre la sustentabilidad. O setor sucroenergético, responsável pela produção de cana-de-açúcar e sua transformação em açúcar, álcool e/ou energia elétrica, conhece desde o início do século XXI uma nova fase de expansão baseada nos termos atuais do desenvolvimento sustentável. O presente artigo objetiva analisar no período contemporâneo o modo como as políticas públicas nacionais e internacionais, juntamente com o agronegócio sucroenergético e os atores locais, apropriaram-se do discurso da sustentabilidade, bem como compreender como as medidas decorrentes desse novo paradigma findaram em justificar a expansão do setor sucroenergético. A metodologia é baseada na pesquisa bibliográfica, no levantamento de dados agropecuários, assim como na análise de programas de desenvolvimento e, por fim, em pesquisas de campo. O trabalho evidencia que a apropriação do discurso do desenvolvimento sustentável se tornou estratégico para a manutenção e expansão do setor sucroenergético, expoente as suas ações em favor do meio ambiente. Contudo, foi verificado que os atores admitem as contradições existentes entre os princípios da conservação do meio ambiente e a realidade dos atos decorrente do discurso da sustentabilidade.
