Biodiversity and nutrition in rice-based aquatic ecosystems

摘要: Abstract The cultivation of most rice crops in irrigated, rainfed and deepwater systems offers a suitable environment for fish other aquatic organisms. Indeed, it comes as no surprise those who produce that rich source biological diversity is to be found rice-based ecosystems. Wild gathered foods, from the habitat, provide important diversity, nutrition food security resources ricefield environments supply essential nutrients are not adequately diet. Development plans focus only on increasing yields may possibly give people more eat, but at same time take away many animals plants harvested around fields. Many organisms ecosystems also play an role control agents vectors pests. Moreover, farmers have experienced concurrent culture with often increases yields. This reflected increase net income which reportedly 7–65% higher rice-fish farms compared monoculture farms. Rice fields harbour species under threat extinction. understanding value biodiversity needs well integrated into national agricultural embrace concepts ecosystem approach agrobiodiversity environment.
