“…To improve the low suitability in Amsterdam and Ghent to a fair level, clarity should be increased, often in combination with a reduction of fecal pollution (for which E. coli bacteria are used as indicator) and/or cyanobacteria. These findings are in line with a study in a tropical urban lake (Azevedo Lopes et al 2020) that showed that suitability for contact recreation was most limited by low visual water clarity, fecal contamination and cyanobacterial blooms. The role of fecal pollution also has been reported in analyses of gastrointestinal illness outbreaks under urban canal or river swimmers in European cities (Hall et al 2017;Joosten et al 2017).…”

“…The role of fecal pollution also has been reported in analyses of gastrointestinal illness outbreaks under urban canal or river swimmers in European cities (Hall et al 2017;Joosten et al 2017). Studies in designated bathing water typically focus on water quality parameters only (e.g., Nagels et al 2001;Azevedo Lopes et al 2020). Our study in urban waterways, that are not designated bathing waters, indicates that for further improvement of the suitability for primary contact recreation to a good or excellent level, more parameters need to be considered, especially depth close to the shore.…”

Canals and canalized rivers form a major part of surface water systems in European delta cities and societal ambitions to use these waters increase. This is the first assessment of how suitability of these waters can improve for three important uses: transportation, thermal energy extraction (TEE) and recreation. We assess suitability with Suitability Indices (SIs) and identify which alterations in the water system are needed to improve SI scores in Amsterdam, The Netherlands, and Ghent, Belgium. The results show spatial variability in suitability scores. Current suitability for transportation is low (SI score = 1) to excellent (SI score = 4), for TEE fair (SI score = 2) to excellent (SI score = 4), and suitability for recreation is low (SI score = 1). Suitability could improve by enlarging specific waterway dimensions, increasing discharge and clarity, and by enhancing microbiological water quality. The same methodology can be applied to optimize designs for new water bodies and for more water uses.

“…Water quality deterioration of inland freshwater bodies is one of the main ecological and environmental challenges that has been faced by developing countries for decades. This undesirable phenomenon is evident in many areas from Latin America to Asia and Africa (Basturk 2019;Diaz-Casallas et al 2019;Gradilla-Hernandez et al 2020;Lopes et al 2020;Luyiga et al 2015). Increasing pollution in freshwater systems in less-developed regions such as Africa poses risks to public health, food security, and biodiversity (UN-Water 2016).…”

Tanzania is the only country bordering all three transboundary East African Great Lakes, i.e., Lake Victoria, Lake Tanganyika, and Lake Nyasa (Lake Malawi). This study investigated the spatiotemporal variability of basic physicochemical parameters of nearshore surface waters in Mwanza Gulf (Lake Victoria), Kigoma Bay (Lake Tanganyika), and Wissmann Bay (Lake Nyasa). Water quality was evaluated using the water quality index (WQI) method. Results showed that N and P nutrient pollution was relatively severe in central and southern parts of Mwanza Gulf owing to external agricultural emissions and internal release associated with physically disturbed sediment resuspension. External inputs from inflowing surface runoffs from the city of Mwanza typically enhanced N loading in northern parts of the gulf during the rainy season. Poor water quality was found in central and southern parts of Mwanza Gulf, especially in the rainy season. Algal blooms and NH 4 + -N (total P and total N) were the main factors driving water quality degradation in the rainy (dry) season. Kigoma Bay and Wissmann Bay both had good water quality, except in river mouth areas in Lake Nyasa during the rainy season. The degradation in water quality was caused primarily by increased land-based nutrient and turbidity inputs. To respond to challenges associated with climate change and local socioeconomic development, long-term monitoring of the lacustrine environment and systematic limnological studies will be required, not only in the three bays but also more widely throughout the three lakes and their basins.

“…Neste contexto, os processos de urbanização desordenados tem gerado diversos impactos ambientais (KOOP e VAN LEEUWEN 2017)associadosa alterações na dinâmica hidrológica (IPCC, 2014;SERRAO-NEWMAN et al, 2017), degradação na qualidade das águas superficiais (TUCCI, 2008;LOPES et al, 2019),redução da recarga de sistemas aquíferos (FELLIPE et al, 2011) e alterações climáticas locais (MACHADO e ASSIS, 2016).Além disso, o referido processo de "metropolização" não foi acompanhado, em níveis adequados, pelo atendimento da população urbana por serviços de saneamento básico. Com as deficiências no setor de saneamento básico, os planos e projetos de controle e/ou combate à degradação ambiental, tendem a tornar-se pouco eficazes (LOPES et al, 2003), expondo especialmente a populaçãoresidente nas periferias e subúrbios (ex.…”

A proposta de Macrozoneamento da Região Metropolitana de Belo Horizonte (RMBH), ocorrida entre 2013-2015, deu legitimidade à intervenção e regulação do poder público sobre a dinâmica territorial, intermediando conflitos e conciliando interesses, por meio da delimitação de Zonas de Interesse Metropolitano (ZIM). Deste modo, busca-se estabelecer conjuntos de uso e apropriação do território conforme suas características intrínsecas, tendências e necessidades, associando formas de apropriação do território às dinâmicas atuais e futuras. Neste contexto, este trabalho tem por objetivo a delimitação e definição de parâmetros que possibilitem a identificação de áreas, ou zonas, com similitudes quanto às suas características ambientais, especialmente em relação à necessidade deconservação/preservação, recuperação e uso, que subsidiem a delimitação das ZIM. Foi utilizado a metodologia relativa aos processos de zoneamento ambiental, disponibilizada pelo Ministério do Meio Ambiente e a técnica de análise multicritérios, visando determinar o grau de semelhança e a compatibilidade entre as áreas previamente sugeridas no processo de macrozoneamento e aquelas identificadas neste estudo. Conclui-se que, diante do significativo número de áreas degradadas e/ou precariamente protegidas, torna-se fundamental a efetivação do planejamento, gestão e manejo das áreas verdes e de proteção ambiental visando à promoção da sustentabilidade socioeconômica da população que reside na RMBH.
