AgroHidro: rede de pesquisa em agricultura e recursos hídricos.
O crescimento populacional demandará mais alimentos e fibras, fato que, aliado às novas demandas bioenergéticas de bases renováveis, alterará os padrões atuais de uso dos recursos hídricos no meio agrícola. O aumento da competição pelo uso da água entre os diversos setores da sociedade implica na necessidade de utilizar esse recurso hídrico de modo mais eficiente, garantindo a sustentabilidade da produção nos diferentes setores da sociedade. Isto assegurará o desenvolvimento e a competitividade econômica do País, de forma diferenciada de outros
A manifesto for future generation cloud computing: research directions for the next decade
The Cloud computing paradigm has revolutionised the computer science horizon during the past decade and has enabled the emergence of computing as the fifth utility. It has captured significant attention of academia, industries, and government bodies. Now, it has emerged as the backbone of modern economy by offering subscription-based services anytime, anywhere following a pay-as-you-go model. This has instigated (1) shorter establishment times for start-ups, (2) creation of scalable global enterprise applications, (3) better cost-to-value associativity for scientific and high performance computing applications, and (4) different invocation/execution models for pervasive and ubiquitous applications. The recent technological developments and paradigms such as serverless computing, software-defined networking, Internet of Things, and processing at network edge are creating new opportunities for Cloud computing. However, they are also posing several new challenges and creating the need for new approaches and research strategies, as well as the re-evaluation of the models that were developed to address issues such as scalability, elasticity, reliability, security, sustainability, and application models. The proposed manifesto addresses them by identifying the major open challenges in Cloud computing, emerging trends, and impact areas. It then offers research directions for the next decade, thus helping in the realisation of Future Generation Cloud Computing
National Assessment of Human Health Effects of Climate Change in Portugal: Approach and Key Findings
In this study we investigated the potential impact of climate change in Portugal on heat-related mortality, air pollution–related health effects, and selected vectorborne diseases. The assessment used climate scenarios from two regional climate models for a range of future time periods. The annual heat-related death rates in Lisbon may increase from between 5.4 and 6 per 100,000 in 1980–1998 to between 8.5 and 12.1 by the 2020s and to a maximum of 29.5 by the 2050s, if no adaptations occur. The projected warmer and more variable weather may result in better dispersion of nitrogen dioxide levels in winter, whereas the higher temperatures may reduce air quality during the warmer months by increasing tropospheric ozone levels. We estimated the future risk of zoonoses using ecologic scenarios to describe future changes in vectors and parasites. Malaria and schistosomiasis, which are currently not endemic in Portugal, are more sensitive to the introduction of infected vectors than to temperature changes. Higher temperatures may increase the transmission risk of zoonoses that are currently endemic to Portugal, such as leishmaniasis, Lyme disease, and Mediterranean spotted fever

Viabilidade Tecnica da Irrigacao em Citros no Norte e Nordeste do Parana.
As regioes Norte (Londrina) e Noroeste (Paranavaí) do Parana foram estudadas quanto a viabilidade tecnica da irrigacao em citros. Utilizou-se a metodologia de comparacao entre regioes sob os aspectos de clima e solo, tomando como parametros a temperatura, insolacao, precipitacao, capacidade de armazenamento de agua no solo e balanco hidrico diario. A «condicao-padrao» assumida foi a area citricola irrigada da Fazenda Sete Lagoas, em Mogi Guaçu, SP. Os resultados permitiram verificar alto potencial de resposta da producao de frutos citricos sob irrigacao nas diferentes condicoes estudadas
