A sustainable food system is made up of environment, process and people by which farmers produce products that are processed and bought in the market without any harm to the ecosystem, natural resources and with long term environmental benefits. The food production method must be changed globally to reduce the effect on resources so that it does not become depreciated and support for food production in future. It is a major concern in the growing population in the world to ensure sustainable supply of food as it is one of the fundamental areas that lacks awareness today.
Usually developing country farmers are working to improve the sustainability of food production. Sustainable agriculture can help increase the yields. It helps improve food production and security in short term and long term. It helps ensure resources are available indefinitely, barring some abrupt circumstances. This means these nations can feed their populations and become self-sustaining. Like other inexpiable activities, food production adds to water shortage, climate change and soil deterioration.
The degree of ecological effect of food production identifies with where and how the nourishment is delivered and the neighborhood accessibility of characteristic assets, for example, water and soil.
Farmers may likewise utilize reused wastewater, which may somehow or another have been disposed of, to help moderate this major resource. Doing so could likewise help improve sanitation on the board. The extension of horticulture has been perhaps the biggest effect on the earth. It has changed environments and is perhaps the best strain for biodiversity.
With changes in precipitation designs, farmers face double dangers from flooding and dry season. The two boundaries can crush crops. Flooding washes away rich topsoil that farmers rely upon for productivity, while desiccation dries it out, making it all the more effortlessly overwhelmed or washed. Higher temperatures increment harvests\' water needs, making them much increasingly defenseless during dry periods. Various types of weeds, creepy crawlies profit by higher temperatures and raised CO2, expanding their capability to harm crops and making budgetary hardship for ranchers. Moving atmospheres additionally imply that agrarian nuisances can grow to new zones where ranchers hadn\'t recently managed them.\nWith higher temperatures, the vast majority of the world\'s glacial masses have started to retreat; influencing farmers who rely upon cold tempered water for irrigation. Rising ocean levels, in the meantime, elevate flood perils for beach front homesteads, and increment saltwater interruption into seaside freshwater springs—making those water sources unreasonably salty for irrigation. For using the natural resources productively, we should do the following:
The nourishment supply, especially as far as discharge of ozone depleting substances, has impacts at all phases of the ecosystem. On the other hand, the rural stage is the single biggest ozone depleting substances producer with meat and dairy items as the most ozone harming substances serious nourishments. Even so, the job of people and their utilization designs significantly affect the food management and its production and the populace allowance of faith based expectations and mentalities will address whether the long term maintainability of the food store network can be accomplished.
