Variability and trends of the rainy season in West Africa with a special focus ...
Mendes, Orlando; Correia, Ezequiel; Fragoso, MarceloThis study provides a novel assessment of trends in rainy season behavior (1981–2020) in West Africa by analyzing highresolution rainfall data from CHIRPS 2.0. Additionally, it presents the frst comprehensive study of rainy season characteristics in Guinea-Bissau, based on an analysis of the country's available observational data, over the same period. The agronomic method was used to determine the rainfall ons...
Recent changes in climate extremes in Guinea-Bissau
Mendes, Orlando; Fragoso, MarceloGuinea-Bissau has experienced the tangible effects of climate change in recent years. An examination of the annual and monthly precipitation patterns from 1960-2020 indicates an overall decreasing trend in climatological series. In contrast, the monthly average maximum and minimum temperatures exhibit significant increasing trends during the same period. Analysing daily rainfall and maximum and minimum temperat...
THE INFLUENCE OF ARTERIAL HYPERTENSION ON ISCHEMIC STROKE: CLOSE RELATIONSHIP T...
Saraiva, Bárbara; Ostapiuk, Ivanna; Tavares Valente, Catarina; Coelho, Sónia; Mendes, Orlando; Fernandes, Ana Rita; Blanco Torres, CelestinaIntroduction: The Cerebral Vascular Accident (CVA) is an important cause of death in Europe and the primary cause of death in Portugal, most of which is ischemic in origin (69-75%). Arterial hypertension (HTN) is the most important risk factor for cardiovascular morbidity and death, being a major risk factor for ischemic stroke. The present study aims to assess the prevalence of hypertension as a risk factor in...
The (dis)engagement of mangrove forests and mangrove rice in academic and non-a...
Sousa, Joana; Campos, Rita; Mendes, Orlando; Lopes, Paula Duarte; Matias, Madalena; Rosa, Ana Paula; Mendes Fernandes, Raul; Cruz, CristinaCoastal areas in Guinea-Bissau and elsewhere in West Africa are bordered by mangrove forests. In several of these places, swaths of mangrove forest have been removed and the landscape has been technologically adapted for the production of mangrove rice-a regionally important staple. However, the effects of global warming, in particular sea-level rise, pose challenges to these socioecological environments. In th...
Assessment of the record-breaking 2020 rainfall in Guinea-Bissau and impacts of...
Mendes, Orlando; Fragoso, MarceloThe impacts of Climate Change are quite visible in Guinea-Bissau. Greater irregularity at the beginning and end of the rainy season, as well as in relation to the interannual variability of precipitation, are evidence that shows these phenomena in West African countries and particularly in Guinea-Bissau, where the agriculture is rain-fed. The year 2020 was characterized as very rainy in comparison to the climat...

Indicadores das mudanças climáticas no leste da Guiné-Bissau e adaptação camponesa
Mendes, OrlandoA região de Gabú, localizada no leste da Guiné-Bissau e, em particular, os sectores de Pirada e Pitche, estão ameaçados pelo efeito das mudanças climáticas, já que nestes contextos a capacidade de adaptação a estas mudanças é limitada. Este trabalho identificou os principais indicadores das mudanças climáticas e as estratégias de adaptação dos camponeses. Foram realizados inquéritos sobre as perceções dos campo...
