The effect of organic farming on water reusability, sustainable ecosystem, and food toxicity

Authors: Parizad, S. and Bera, S. (2021)


Abstract:

Water is a fundamental necessity for people’s well-being and the ecosystem’s sustainability; however, its toxicity due to agrochemicals usage for food production leads to the deterioration of water quality. The poor water quality diminishes its reusability, thus limiting efficient water usage. Organic farming is one of the best ways that does not only reduce the deterioration of water quality but also decrease food toxicity. In organic farming, the crop is grown with no/less chemical usage. Besides, organic farming maintains biodiversity and reduces the anthropogenic footprint on soil, air, water, wildlife, and especially on the farming communities. Fields that are organically managed continuously for years have fewer pest populations and were attributed to increased biodiversity and abundance of multi-trophic interactions as well as to changes in plant metabolites. Fewer insect pests (pathogen vectors), in turn, would result in fewer crop diseases and increase crop production. This review highlights that organic farming may play a critical role in the reduction of pests and pathogens, which eventually would reduce the need for chemical reagents to protect crops, improving yield quality and water reusability.
