In order to minimize environmental effect and maintain the long-term viability of our food supply, sustainable food production systems are crucial. Conventional farming methods have been a major factor in environmental problems such as soil erosion, shortages of water, climate change, and biodiversity loss. These issues endanger future food security in addition to harming the environment. To solve these issues, a shift to sustainable agriculture is essential. Sustainable practices promote approaches that are socially, economically, and environmentally responsible, thereby improving all four pillars of food security: availability, access, utilization, and stability. Humans can reduce farming's detrimental effects on the environment, protect natural resources, and increase the resilience of agricultural ecosystems by implementing sustainable food production systems. By using a comprehensive strategy, food production may be made to fulfil current requirements without sacrificing the ability of future generations to meet their own. In the end, sustainable agriculture aims to ensure a stable and secure food supply for all by promoting a positive link between farming and the environment. It goes beyond simply producing food. This paper explains how green technologies can support sustainable food production. Digital agriculture, urban farming, and food nanotechnologies are deeply explained and highlighted for promoting sustainable practices. This paper stresses on the need for sustainable practices that balances long-term food security.
