Previous studies have combined climate, crop and economic models to examine the impact of climate change on agricultural production and food security, but results have varied widely due to differences in models, scenarios and input data. Recent work has examined (and narrowed) these differences through systematic model intercomparison using a high-emissions pathway to highlight the differences. This paper extends that analysis to explore a range of plausible socioeconomic scenarios and emission pathways.
This event, hosted at ODI in London, was convened to discuss the use of new technologies to map and document land rights, and their impact on land registration and administration, and pr
Climate change is a significant and growing threat to food security—already affecting vulnerable populations in many developing countries, and expected to affect ever more people in more places, unless action is taken beginning today. Current scenarios for business-as-usual farming under climate change project growing food security challenges by 2050. Worst hit will be underdeveloped regions of the world where food insecurity is already a problem and populations are vulnerable to shocks (Rosegrant et al. 2014).
Property rights to land represent the key institutional asset on which rural people build their livelihoods. In fact, in many countries, landlessness is the best predictor of poverty. The nature of farmers’ property rights to land substantially impacts their willingness and ability to adopt productivity-enhancing inputs and investments.
O PCP insistiu e o Governo aceitou recuar. Pelo menos por agora, porque a ideia é voltar à carga depois do projecto piloto do cadastro simplificado. E, aí, já só será preciso um decreto-lei do Governo. Proposta será votada esta noite no Parlamento.
Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are a further threat. But the world can produce more food and can ensure that it is used more efficiently and equitably.
Segundo projeto, serão destinados 100 hectares de terras para cultivar milho, mandioca e outras culturas para serem comercializados em cinco feiras livres.
A maior reserva indígena de Dourados, no sul de Mato Grosso do Sul, vai receber subsídio e orientação para produção de produtos orgânicos. O projeto da Secretaria de Agricultura Familiar vai preparar 100 hectares de terra para cultivar milho, mandioca e outras culturas para comercializar o excedente em cinco feiras livres na cidade.
