In fact growing population, depleting resources and the increasing threat of climate change, it will be impossible to fulfill the needs of the future unless we transition to sustainable food and agricultural systems that would ensure world food security, provide economic and social opportunities, and protect the ecosystem. It takes into account biological methods of plant protection and ensures their integration, in order to control the development of pests while minimizing the use of chemical pesticides.

By adopting sustainable practices, farmers will reduce their reliance on nonrenewable energy, reduce chemical use and save scarce resources. Keeping the land healthy and replenished can go a long way when considering the rising population and demand for food. Sustainable agriculture and food systems such as organic agriculture and agro-ecology improve food security, eradicate hunger and are economically viable, while conserving land, water, plant and animal genetic resources, biodiversity and ecosystems and enhancing resilience to climate change and natural disasters. As against conventional farming, sustainable farming offers to provide healthy food by transitioning to agriculture that can adapt to unavoidable climate change whilst preserving biodiversity, sustaining the quality of soils, and improving the livelihood of farmers. With growing population, depleting resources and the increasing threat of climate change, it will be impossible to fulfill the needs of the future unless we transition to sustainable food and agricultural systems that would ensure world food security, provide economic and social opportunities, and protect the ecosystem. Sustainable agriculture and food systems such as organic agriculture and agro-ecology improve food security, eradicate hunger and are economically viable, while conserving land, water, plant and animal genetic resources, biodiversity and ecosystems and enhancing resilience to climate change and natural disasters. Sustainable agriculture protects and renews soil fertility and the base of natural resources. It also optimizes the management and use of farm resources. It reduces the use of non-renewable resources and purchased production inputs. Switching to sustainable farming practices can help reduce air, water, and soil pollution and protect the biodiversity that sustains human life. Combating climate change through sustainable food production decreases extreme weather, often leading to food insecurity. Sustainable food production practices can improve soil fertility and lessen erosion; prevent the pollution of water, land, and air; and support biodiversity, all of which are crucial for environmental health and sustained agricultural output. Sustainable agriculture is farming in such a way to protect the environment, aid and expand natural resources and to make the best use of nonrenewable resources.

In fact these crops protect and build soil health by preventing erosion, replenishing soil nutrients, and keeping weeds in check, reducing the need for fertilizers and herbicides. Reducing or eliminating tillage. Traditional plowing prepares fields for planting and prevents weed problems but can cause soil loss. Sustainable agriculture and food systems such as organic agriculture and agro-ecology improve food security, eradicate hunger and are economically viable, while conserving land, water, plant and animal genetic resources, biodiversity and ecosystems and enhancing resilience to climate change and natural disasters. Sustainable food production is “a method of production using processes and systems that are non-polluting, conserve non-renewable energy and natural resources, are economically efficient, are safe for workers, communities and consumers, and do not compromise the needs of future generations”. Sustainable agriculture can herald the second green revolution with high-yielding crop varieties, proper crop rotation, sustainable irrigation, modern farming methods, agri-tech and policy and marketing support. This will help the agriculture sector and agro-based industries, including the agri-tech sector. As against conventional farming, sustainable farming offers to provide healthy food by transitioning to agriculture that can adapt to unavoidable climate change whilst preserving biodiversity, sustaining the quality of soils, and improving the livelihood of farmers. The development of sustainable food production and biodiversity can help reduce hunger, improve the food security status and provide a nutritious diet for the world's population. Shifting food and fiber production to a sustainable system helps attain both objectives. Sustainable agriculture practices are intended to protect the environment, expand Earth's natural resources, and maintain and improve soil fertility.
