The need to meet the food demand of a growing global population runs into one major self-defeating cycle: intensive conventional agriculture damages biodiversity—what with chemicals and monocrops destroying plants diversity and wildlife habitats. Eventually, reduced biodiversity jeopardizes long-term food security. Introducing organic farming in a conventionally-farmed landscape would help mitigate the issue, according to scientific research. Agricultural practices than banish chemical and inorganic fertilizers, and allow for higher crop diversity, leads to higher weed diversity locally and in nearby conventionally farmed fields, according to a study published yesterday in Proceedings of the Royal Society of London.
