Agricultural practices to improve irrigation sustainability
Palma, Patrícia; Tomaz, AlexandraAgriculture accounts for approximately 70% of global water usage [1,2]. Although the use of water in agriculture yields considerable gains in productivity, thereby contributing significantly to food production and security, the agricultural sector is increasingly required to justify its use of water and is under growing scrutiny [3,4,5]. To address water governance and ensure fair access to water across sectors...
Tools for managing metal contaminated areas: multidisciplinary approach to deve...
Oliveira, Rui Jorge; Caldeira, Bento; Palma, Patrícia; Costa, Maria João; Fialho, AnaThis work aims to develop an environmental management model specifically designed for mining areas that have been contaminated by toxic metals. A sustainable management model is suggested to be established, utilizing a combination of developed tools. This model will provide tools and strategies to effectively manage and mitigate the environmental impact of such contamination, with the goal of promoting an incre...
Instrumento de gestão de áreas contaminadas por metais combinando dados de Quím...
Oliveira, Rui Jorge; Caldeira, Bento; Palma, Patrícia; Costa, Maria João; Fialho, AnaO Projeto INCOME propõe a criação de um modelo de gestão ambiental para áreas mineiras contaminadas por metais tóxicos. Este modelo integra os resultados da aplicação de um conjunto de métodos analíticos e instrumentos de monitorização de áreas contaminadas, como análises biofísicas, química do solo e da água (parâmetros de qualidade e quantificação de metais potencialmente tóxicos em amostras de solo e água), ...
Optical characterization of the S˜ao Domingos Mine heaps with satellite imaging
Oliveira, Rui Jorge; Caldeira, Bento; Costa, Maria João; Palma, Patrícia; Fialhgo, AnaThe INCOME Project proposes the creation of an environmental management model for mining areas contaminated by toxic metals [1]. This model integrates the results of the application of a set of analytical methods [2] and instruments for monitoring contaminated areas, such as biophysical analyses, soil, and water chemistry, geophysics, and satellite [3] hyperspectral remote sensing. Data from all research will b...
Projeto ENGAGE: Uma abordagem transdisciplinar para a gestão colaborativa de nu...
Costa, Diogo; Potes, Miguel; Liu, Jian; Rodriguez, Divina; Palma, Patrícia; Dace, Elina; Pereira, Paulo; Elbakidze, MarineAs alterações climáticas estão a afetar a dinâmica de nutrientes em bacias hidrográficas, intensificando fenómenos como a poluição difusa e a eutrofização, com impactos diretos na qualidade da água, na integridade dos ecossistemas aquáticos e na resiliência das comunidades humanas. A diversidade regional dos fatores climáticos e antropogénicos que contribuem para a poluição por nutrientes na Europa acentua a co...
Patterns, risks, and forecasting of irrigation water quality under drought cond...
Tomaz, Alexandra; Catarino, Adriana; Tomaz, Pedro; Fabião, Marta; Palma, PatríciaThe seasonal and interannual irregularity of temperature and precipitation is a feature of the Mediterranean climate that is intensified by climate change and constitutes a relevant driver of water and soil degradation. This study was developed during three years in a hydro-agricultural area of the Alqueva irrigation system (Portugal) with Mediterranean climate conditions. The sampling campaigns included collec...
Avaliação de metais em solos com culturas de girassol e milho (caso de estudo: ...
Catarino, Adriana; Martins, Inês; Mourinha, Clarisse; Tomaz, Alexandra; Dôres, José; Patanita, Manuel; Palma, PatríciaO objetivo do trabalho foi avaliar a concentração e biodisponibilidade de metais, em três solos plantados com girassol e milho no aproveitamento hidroagrícola Brinches-Enxoé, durante o ciclo vegetativo de 2018 (início: T1 (abril) e final: T2 (outubro)). A análise foi realizada por espectrometria de massa com plasma indutivamente acoplado (ICP-MS), posterior a uma digestão com água-régia para metais totais e uma...
Multidecadal water quality trends across 15 European river basins along a Medit...
Costa, Diogo; Liu, Jian; Palma, PatríciaWater quality degradation is a major issue in Mediterranean regions, but identifying the key natural and human drivers remains challenging, requiring large–scale studies for meaningful synthesis and comparison. This study analyzed a vast Mediterranean dataset spanning 89,015 km 2 across 15 Iberian river basins along a climate gradient (cooler-wetter north to warmer-drier south), 3 decades, 3441 stations, 19 par...
Integrating ecotoxicological assessment to evaluate agricultural impacts on aqu...
Clarisse Mourinha; Custódio, Mariana; Anastácio, Pedro; Catarino, Adriana; Palma, PatríciaThis study analyzed the use of a toolbox to evaluate the impact of agricultural activity on the water quality/status classification of a hydro-agricultural reservoir (Lage reservoir, Southern Portugal). The framework integrated the quantification of a group of 51 pesticides and ecotoxicological endpoints with organisms from different trophic categories (the bacterium Aliivibrio fischeri, the microalga Pseudokir...
Produtos farmacêuticos ameaçam bacias hidrográficas europeias
Novais, Maria Helena; Palma, Patrícia; Morais, Manuela; Penha, Alexandra Marchã; Fialho, Luís; Horta, PedroThe concern with the presence of pharmaceuticals and their potential impacts on aquatic ecosystems, associated with the lack of systematized information, due to legislative gaps, motivated this literature review. Published studies on pharmaceuticals’ detection and quantification in treated effluents from WWTPs and in watersheds, in Portugal, Spain, France and the United Kingdom were consulted. The transversalit...
