“…As zonas ripárias têm uma importância fundamental na conectividade dos habitats em ambientes urbanos (ATKINSON; LAKE, 2020), contudo as alterações urbanas mais visíveis se dão diretamente nos canais fluviais, como por exemplo na canalização dos rios em função do crescimento urbano (LI et al, 2016;PALMER;RUHI, 2019). A oferta e a qualidade das águas no Brasil e no mundo são influenciadas não só pelas condições meteorológicas mas também pelo mau gerenciamento das bacias hidrográficas, incluindo a reduções de florestas ripárias, legalmente estipuladas, e o aumento do desmatamento de cabeceiras (COHEN, 2016;RANDHIR, 2018). Em Sorocaba as áreas de APPs representam 18,90% (8.499 ha) da paisagem e apenas 44,7% dessa área é ocupada por remanescentes florestais, sendo o restante tomado por atividades agrícolas, áreas urbanas e campos antrópicos (MELLO et al, 2014).…”

Resumo: Devido aos impactos ambientais e custos de coleta, transporte e disposição final de resíduos sólidos domiciliares, a compostagem descentralizada da fração orgânica desses resíduos (próximo à fonte geradora como condomínios, escolas, restaurantes etc.) representa uma estratégia financeira, social e ambiental atraente. A compostagem descentralizada é recomendada principalmente para países em desenvolvimento, nos quais, a maior porcentagem do lixo gerado é constituída de matéria orgânica passível de compostagem. O objetivo do presente estudo foi testar e aprimorar um reator de compostagem de aeração forçada com fluxo ascendente para tratar resíduos de cozinha de restaurantes de uma área turística e portuária na cidade de Kalmar, na Suécia. O equipamento foi originalmente desenvolvido por um grupo de técnicos e pesquisadores suecos com a capacidade para processar aproximadamente 120 kg dia -1 . O estudo, com vistas à tropicalização da mencionada tecnologia fez parte de um projeto mais amplo de cooperação entre a antiga Universidade de Kalmar (atualmente Linnaeus University) e a Universidade do Estado do Rio de Janeiro (UERJ). O presente artigo baseou-se nos resultados obtidos durante o período de treinamento e teste do reator, no verão europeu, para o tratamento dos resíduos orgânicos provenientes de três restaurantes de pequeno porte localizados na marina, e cujos resíduos orgânicos apresentavam alto percentual de carboidratos, gordura e frutas cítricas, característico das comidas servidas no local.Palavras-chave: compostagem, reator de aeração forçada, pH, resíduo orgânico domiciliar.

“…Forested watersheds worldwide are related to better water quality than watersheds with other land uses [8] [9] [10] [11]. Keeping forest areas in agricultural or urban watersheds can control biogeochemical cycles, protect against erosion, reduce pollutant loading, decrease nutrient runoff, and lower water temperature [12] [13]. Thus, native vegetation in watersheds can provide many water-related ecosystem services, including drinking water, regulating water streamflow and flood events, climate regulation, fish production, and creating opportunities for water-based recreation and culture [14] [15].…”

Payments for ecosystem services (PES) have been created worldwide to assist watershed management and improve or maintain water quality. Considering their importance, we conducted a holistic review of payment for water-related ecosystem services to understand how this instrument has been applied in watershed management worldwide. First, we identified the watershed management actions considered by the PES programs and the challenges of implementing water-related PES. After we identified the methods and criteria used to define priority areas for water-related PES. Our review considered articles published on the Web of Science from 2011 to 2022. We found 236 articles relating PES to water resources, highlighting the main water conservation strategies: native vegetation conservation, native vegetation restoration, and implementing best agricultural practices. The method most frequent was interview, followed by the use of technologies, document analysis, and hydrological models. Another significant result was that priority areas for receiving PES are mainly riparian zones, areas near or with native vegetation cover, areas with higher erosion potential, steep areas, and areas with socially vulnerable communities. This review was crucial to identify efficient water resource conservation strategies and potential challenges in the implementation and development of PES programs.

“…Natural vegetation has an important role in biogeochemical cycles in tropical agricultural watersheds, and studies show that these ows are stronger in low-order streams, providing protection against erosive processes, sedimentation in water bodies, pollutants retention, excessive leaching of nutrients, and increased water temperature (Schilling and Jacobson 2014;Tanaka et al 2016;Taniwaki et al 2017;Mello et al 2018a). Forest conservation and restoration of watersheds have been recommended as the best solution for keeping or improving water quality for public water supply (Bu et al 2014;Vettorazzi and Valente 2016;Mello and Randhir 2018;Bakure et al 2020).…”

Low-order streams are important regions for river formation and are highly vulnerable to changes in terrestrial systems. Thus, the land-use/land-cover plays an important role in the maintenance of water quality. However, only its composition may not explain the spatial variation in water quality, because it does not consider landscape con gurations. In this context, the study aimed to evaluate the forest cover pattern effects on water quality on low-order streams, which integrated an agricultural landscape. Applying a paired watershed method, we selected watersheds classi ed according to their morphometry and average slope to discard other physical factors that could in uence the water quality. Land-use/landcover pattern was analyzed for composition and forest cover con guration using landscape metrics, including the riparian zone composition. Water quality variables were obtained every two weeks during the hydrological year. This way, watersheds had similar morphometry, slope, and land-use/land-cover composition but differed in landscape con guration. Watershed with more aggregated forest cover had a better water quality than the other one. The results show that forest cover contributes to water quality maintenance, while forest fragmentation in uences the water quality negatively, especially in sediment retention. Agricultural practices are sources of sediment and nutrients to the river, especially in steep relief. Thus, in addition to land-use/land-cover composition, landscape pattern must be considered in management of low-order streams in tropical agricultural watersheds.
