    Agreement is developing among agricultural scientists on the emerging inability of agriculture to meet growing global food demands. Changes in trends of weather conditions projected by global climate models will challenge physiological limits of crops and exacerbate the global food challenge by 2050. These climate- and constraint-driven crop production challenges are interconnected within a complex global economy, where diverse factors add to price volatility and food scarcity. Our scenarios of the impact of climate change on food security through 2050 for internationally traded crops show that climate change does not threaten near-term US food security due to the availability of adaptation strategies. However, as climate continues to change beyond 2050 current adaptation measures will not be sufficient to meet growing food demand. Climate scenarios for higher-level carbon emissions exacerbate the food shortfall, although uncertainty in projections of future precipitation is a limitation to impact studies

    Food security, farming, and climate change to 2050: Scenarios, results, policy options

    As the global population grows and incomes in poor countries rise, so too, will the demand for food, placing additional pressure on sustainable food production. Climate change adds a further challenge, as changes in temperature and precipitation threaten agricultural productivity and the capacity to feed the world's population. This study assesses how serious the danger to food security might be and suggests some steps policymakers can take to remedy the situation.global food security, Climate change, Food prices, Agricultural productivity,

    Climate change: Impact on agriculture and costs of adaptation

    Get PDF
    "The Challenge The unimpeded growth of greenhouse gas emissions is raising the earth’s temperature. The consequences include melting glaciers, more precipitation, more and more extreme weather events, and shifting seasons. The accelerating pace of climate change, combined with global population and income growth, threatens food security everywhere. Agriculture is extremely vulnerable to climate change. Higher temperatures eventually reduce yields of desirable crops while encouraging weed and pest proliferation. Changes in precipitation patterns increase the likelihood of short-run crop failures and long-run production declines. Although there will be gains in some crops in some regions of the world, the overall impacts of climate change on agriculture are expected to be negative, threatening global food security. Populations in the developing world, which are already vulnerable and food insecure, are likely to be the most seriously affected. In 2005, nearly half of the economically active population in developing countries—2.5 billion people—relied on agriculture for its livelihood. Today, 75 percent of the world’s poor live in rural areas. This Food Policy Report presents research results that quantify the climate-change impacts mentioned above, assesses the consequences for food security, and estimates the investments that would offset the negative consequences for human well-being. This analysis brings together, for the first time, detailed modeling of crop growth under climate change with insights from an extremely detailed global agriculture model, using two climate scenarios to simulate future climate. The results of the analysis suggest that agriculture and human well-being will be negatively affected by climate change: * In developing countries, climate change will cause yield declines for the most important crops. South Asia will be particularly hard hit. * Climate change will have varying effects on irrigated yields across regions, but irrigated yields for all crops in South Asia will experience large declines. * Climate change will result in additional price increases for the most important agricultural crops–rice, wheat, maize, and soybeans. Higher feed prices will result in higher meat prices. As a result, climate change will reduce the growth in meat consumption slightly and cause a more substantial fall in cereals consumption. * Calorie availability in 2050 will not only be lower than in the no–climate-change scenario—it will actually decline relative to 2000 levels throughout the developing world. * By 2050, the decline in calorie availability will increase child malnutrition by 20 percent relative to a world with no climate change. Climate change will eliminate much of the improvement in child malnourishment levels that would occur with no climate change. * Thus, aggressive agricultural productivity investments of US$7.1–7.3 billion are needed to raise calorie consumption enough to offset the negative impacts of climate change on the health and well-being of children." from TextAdaptation, Agriculture, Climate change, Developing countries, food security,

    O EFEITO ABORTIVO DA VINCRISTINA EM CÃES RELATO DE CASO

    O TVT é mais acometido por animais errantes, sendo ele tratado com quimioterápicos, surge a preocupação com os efeitos adversos que decorrem com o tratamento. O sulfato de vincristina leva à toxicidade de reprodução, toxicidade de desenvolvimento e crescimento. O objetivo da utilização dos quimioterápicos na veterinária é prolongar o tempo de sobrevida do animal após o diagnóstico e controlar a progressão da doença. O presente trabalho teve como objetivo relatar um caso de tumor venéreo transmissível na região vulvar, onde o animal encontrava-se gestante, por conta da quimioterapia levou ao aborto e reabsorção dos fetos

    Crash-testing policies; How scenarios can support climate change policy formulation A methodological guide with case studies from Latin America

    Get PDF
    The objective of this handbook is to guide policy makers and practitioners from the public, private and research sector in the development and use of scenarios to support the inclusive formulation of policies and other decision-making processes related to complex issues taking place in changing environments. The lessons shared are based on nine policy formulation processes for climate in Latin America supported by the CCAFS future scenarios project since 2013. Five of these cases are discussed to exemplify the steps described to use scenarios and support the development of policies

    The future of food security, environments and livelihoods in Eastern Africa: four socio-economic scenarios

    Get PDF
    This report presents 4 scenarios for the future of food security, agriculture, livelihoods and environments in East Africa. These scenarios were developed by the CGIAR Research Program on Climate Change, Agriculture and Food Security in collaboration with a wide range of regional stakeholders. The report discusses the theory and development process of the scenarios, then presents detailed scenario narratives, semi-quantitative assumptions for a range of indicators, and finally outputs generated by 2 agricultural economic models, IMPACT and GLOBIOM. The report goes on to discuss the key results from the scenarios and then to describe the use of the scenarios in processes to guide decision-making in the context of East African food security and climate adaptation
