Aquaculture is a major source of protein in Sub-Saharan Africa (SSA), region experiencing rapid population growth, changing lifestyles and preferences, increased health awareness. However, the industry still underdeveloped subsistence nature. Climate change has impacted aquaculture production (AQUAP) SSA because greenhouse gas (GHG) emissions. AQUAP activities also results GHG In SSA, causal effect emissions not yet been empirically established quantified.

Potential of integrated multitrophic aquaculture to make prawn farming sustainable in Bangladesh

Frontiers in Sustainable Food Systems, Journal Year: 2024, Volume and Issue: 8

Published: Oct. 9, 2024

Farmed freshwater prawn ( Macrobrachium rosenbergii ) and black tiger shrimp Penaeus monodon comprise a significant portion of Bangladesh’s seafood exports, raising concerns about their environmental impacts. Freshwater farms, which require relatively high amount feed supply, release 1.0 MT CO 2 -equivalents/year, equating to 18.8 kg e/MT prawn, contributing significantly global warming climate change risks. Integrated Multi-Trophic Aquaculture (IMTA) offers an alternative farming method conventional systems, as it minimizes greenhouse gas (GHG) emissions Systematically reviewing 112 scientific articles on IMTA, this article recommendations for adopting IMTA promote sustainable in Bangladesh. is undergoing extensive experimentation practice many parts the world, offering economic benefits, social acceptability, sustainability. In addition native species, various indigenous organic extractive mollusks, inorganic plants are available can seamlessly be used tailor system.

Environmental Sustainability in the Culture of Macroalgae, Oysters, and Low-Trophic Fish

Fishes, Journal Year: 2025, Volume and Issue: 10(3), P. 108 - 108

Published: March 3, 2025

Aquaculture plays a crucial role in meeting the needs of growing human population and achieving sustainable development goals outlined Agenda 2030. However, it is essential that this sector grows sustainably. In study, we hypothesized environmental sustainability decreases as trophic level farmed species increases higher integrated systems compared to monocultures. To test these hypotheses, conducted comparative analysis indicators some aquaculture systems, including farming primary producers, filter feeders, low-trophic phagotrophs. We compiled secondary data on eighteen from seven systems. Five are monocultures, macroalgae (Hypnea pseudomusciformis), oysters (Crassostrea gazar) tropical environment, subtropical well tambatinga (hybrid Colossoma macropomum × Piaractus brachypomus) tambaqui (Colossoma macropomum). Additionally, two systems: raised hapa nets (small cage-like enclosures) within Amazon river prawn (Macrobrachium amazonicum) ponds, prawns cohabitating freely same ponds. A benchmark tool was utilized establish reference values for comparing between method developed create indices integrate all indicators. Environmental tends decrease levels rise, supporting initial hypothesis. revealed Integrated Multi-Trophic (IMTA) ultimately have lower than which contrary our expectations.

Increasing soil organic carbon (SOC) in cropland soils improves health and water quality, crop productivity, resilience to climate-driven changes by influencing key processes. However, research on SOC sequestration based bibliometric analyses of highly cited documents is lacking. This study investigated the current status development characteristics, impact, intellectual base, hotspots using Web Science Core Collection databases from 2012 2022. The analysis visualization tools such as Biblioshiny, VOSviewer, CiteSpace, Power BI, Flourish Studio, provided a comprehensive approach for evaluation, identifying trends, knowledge mapping research. findings indicate that United States China dominate global research, with Chinese Academy Sciences leading institution. Key journals include Soil Biology Biochemistry Geoderma. e. trend topic graph indicated “soil carbon” matter” are most persistent themes since 2015. In contrast, recent focuses “climate change mitigation,” health” aggregation”. Moreover, burst citation keywords revealed significant insights into potential role microbes transforming stabilizing matter. present emphasized adopting management practices aimed at enhancing inputs increases C croplands, thus improving help advancing Sustainable Development Goals (SDGs).
