Emerging digital technologies such as AI, precision agriculture, and the IoT are powering smart farming that has the potential to transform agricultural production in developing countries. The chapter mainly discusses how embracing smart farming matters in developing countries from an economic and policy perspective. It has been proven that smart farming can help farmers make more profit and secure food supply by raising the amount of crops they grow, making better use of resources, and lowering production expenses. The main obstacles to using mobile technology more broadly are subpar infrastructure, very many knowing how to use technology, high start-up costs, and vague legislation. The article recommends using subsidies, running extension services through digital media, and increasing rural access to broadband as ways to help close the technology gap. It concludes that using smart farming, underdeveloped countries may be able to grow their agriculture, but success will only come if governments, the private sector, and global bodies come together to fix serious and institutional problems.
