In the recent few years, there has been a  larger degree of awareness among people about the negative effects of chemical-based farming, which is significantly dependent on synthetic pesticides and fertilizers. Conventional farming relies heavily on these toxic substances, which enter the food chain, pollute the groundwater sources, accumulate in living organisms' bodies by biological magnification and end up causing a great deal of harm to the ecosystem. 
So, the need of the hour is to research and develop alternate systems that are ecologically sustainable and complement efforts to preserve the environment. Such alternate methods of agriculture can be called 'Organic Farming'.
This method of cultivation is supplemented by biological pest control, manure, compost etc. and opts to undertake practices such as crop rotation and drop irrigation to avoid over-straining cultivable land. It produces safe, healthy and nutritious food without damaging the environment. 
It replenishes and safeguards the stock of natural resources in human possession. Moreover, there is an growing demand for such organically grown food to provide food safety, security and adequate nourishment to people around the world. 
Organic farming is very beneficial to both producers and consumers. It relies on cheap, organic inputs as opposed to expensive chemical-based agricultural agents. It ensures environmental safety while producing food that has a high nutritional value. 
The challenges that lie before us to promote and encourage organic farming are many. Organic farming is still relatively unpopular due to lack of appropriate agricultural policies, as well as inadequate infrastructural facilities. In order to overcome these hurdles, the relevant authorities must commit themselves to incentivize organic farming.
A wonderful initiative is the International Federation of Organic Agriculture Movements, which represents close to 800 affiliates in 117 countries. Its mission is to, "Lead, unite and assist the organic movement in its full diversity." and its vision is the "worldwide adoption of ecologically, socially and economically sound systems, based on the Principles of Organic Agriculture."  Inspite of many challenges, organic farming helps in sustainable development and allows us to enjoy a better standard of food safety and security.
