The economic and political crisis in Sri Lanka has set an unsuccessful example of the transition from conventional farming and a complete ban on synthetic inputs. According to Ponisio et al., 2015 this can result in reduced yield and lower yield stability (Knapp and van der Heijden, 2018).
Large agri-businesses have control over organic seed and fertilizers. Commercialization of organic farming favours large businesses and causes small farmers disadvantaged (Source). So the question arises whether organic farming would be able to reduce hunger and malnutrition sustainably.
Natural Farming does not rely on agrochemicals, completely based on local farm produce so can be a good alternative to reduce harmful impacts on the environment. However, reduced tillage, use of crop residues and intercropping are similar aspects of conventional and natural farming (Ravishankar et al., 2020).
