Food system perspective on fisheries and aquaculture

-4-28 · ‘Food systems’ are receiving renewed interest as means of moving beyond the productivist agendas that tend to dominate food policy (Béné et al. ).Central to food systems thinking is the transdisciplinary analysis of social and environmental trade-offs and synergies across the whole set of production, provisioning, and consumption activities that affect food security (Ericksen 2008

If the soil is way too wet, the roots are smothered, the roots can''t get any oxygen from the air, and the cells in the roots die. Without those root cells, the rest of the plant dies. Some plants have evolved adaptations to deal with extremely wet soil. Mangroves are trees that live in swampy environments along the coast in the tropics.

2015-6-20 · Increasing resource use efficiency— “more crop per drop”—is important, but if a large fraction of the “crop” is not beneficially used the net result of gains in production are reduced. These kinds of imperfections not only apply to the use of water and food. Similar observations can be made regarding other resources and commodities.

Feeding Methods - an overview | ScienceDirect Topics

Feeding methods (hand-feeding, blower feeding, automatic feeders or demand feeders) may affect tilapia performance. Hand-feeding is recommended in small-scale tilapia farms because it allows the feeder to regulate the amount of feed required, prevent overfeeding and observe fish behaviour and feeding activity. However, automatic feeders, feed blowers and demand feeders are usually used with
