Integrated wetlands for food production

Abstract

The widespread use of compound pelleted feeds and chemical fertilizers in modern food production contribute to a vast amount of residual nutrients into the production system and adjacent ecosystem are major factors causing eutrophication. Furthermore, the extensive development and application of chemical compounds (such as chemical pesticides, disinfectants and hormones used in enhancing productivity) in food production process are hazardous to the ecosystems, as well as human health. These unsustainable food production patterns cannot sustain human living in the long run. Wetlands are perceived as self-decontamination ecosystems with high productivities. This review gives an overview about wetlands which are being integrated with food production processes, focusing on aquaculture.

Unravelling the potential of halophytes for marine integrated multi-trophic aquaculture (IMTA)— a perspective on performance, opportunities and challenges

“…For that reason, if the main goal is water remediation, CWs are the most cost-effective choice and can be used in both open and closed aqua culture systems. Eventually, as highlighted by Chen & Wong (2016), a hybrid approach comprised of both types of growing systems would allow to take advantage of both mechanisms, maximizing nutrient removal and plant biomass production.…”

“…3). The growing modules for halophytes were either hydroponics-or substrate-based, and it appears that the choice of medium depends on the type of intensification being employed for the production of the target fish species (semi-intensive vs. intensive/recirculating aquaculture system [RAS]), as well as halophyte species and biofilter main purpose (wastewater treatment vs. plant biomass production) (Buhmann & Papenbrock 2013b, Chen & Wong 2016. Farmed species from which the effluents originated included different fish and shrimp, and in some studies, artificial solutions mimicking the or ganic load of aquaculture effluents were used , Quintã et al 2015a, de Lange & Pau lissen 2016.…”

Hábitos Alimentares Em Peixes De Água Doce: Uma Revisão Sobre Metodologias E Estudos Em Várzeas Brasileiras

“…De acordo com Junk et al (2014), áreas úmidas são ecossistemas formados a partir da interface entre ambientes terrestres e aquáticos, continentais e costeiros, naturais ou artificiais, permanentes ou periodicamente inundados ou com solos encharcados. Cunico et al (2002) e Fajardo et al (2009) consideram como áreas úmidas as planícies inundáveis ou várzeas, regiões constituídas por solos hidromórficos, com fertilidade variável e elevada produtividade, sendo reconhecidas por possuírem uma rica biodiversidade, um regime hidrológico complexo e por serem os filtros naturais, devido à sua capacidade de retirar compostos potencialmente danosos da água (Chen & Wong 2016). Além disso, as várzeas são dotadas de propriedades edáficas específicas e abrigam uma vegetação com adaptações voltadas à influência espacial e temporal da água (Hesslerová et al 2013, Beuel et al 2016raising concerns about potential impacts on wetlands and the long-term sustainability of such land use trends.…”

Humusica 2, article 17: techno humus systems and global change − three crucial questions

“…Organic products are "better" than corresponding non-organic's because their confection by plants and animals is achieved with a complex living network of relationships. It is well known that agricultural organic soils are more biodiverse than those under intensive agriculture, or that a monoculture must be integrated in a biodiverse landscape in order to resist sustainable exploitation (Chen and Wong, 2016;Dauber and Miyake, 2016;Cluzeau et al, 2009;Ekroos et al, 2016;Funabashi, 2016;Gathorne-Hardy, 2016;German et al, 2017;Hernández et al, 2014;Juárez and Diaz, 2016;Landis, 2017;Rahmann et al, 2017;Soto and Muñoz, 2002;Suso and Del Río, 2015). Living organism's relationships are the accomplishment of a long-term co-evolution.…”
