Modern agronomic innovations for climate resilience and enhanced food security: A review of cutting-edge tools and practices

Abstract

Global agriculture faces a dual imperative: to ensure food security for a growing population while simultaneously building resilience against the escalating impacts of climate change. Traditional agronomic practices, while historically productive, are increasingly insufficient to address these intertwined challenges (Godfray et al., 2010) [41]. This review paper comprehensively examines modern agronomic innovations, focusing on cutting-edge tools and practices that are transforming the agricultural landscape towards greater climate resilience and enhanced food security (Pretty et al., 2011) [95]. We delve into the advancements in precision agriculture, smart farming technologies, and advanced crop modeling that enable data-driven decision-making and optimized resource use (National Research Council, 2010) [83]. The paper explores innovative water management strategies, including advanced irrigation systems and water harvesting techniques, crucial for adapting to changing precipitation patterns (FAO, 2017) [31]. Furthermore, we analyze the principles and applications of regenerative agriculture, vertical farming, and sustainable nutrient management, highlighting their potential to enhance soil health, reduce environmental footprints, and secure food supply chains (Lal, 2015; Despommier, 2009) [67, 24]. The review also provides a detailed overview of enabling technologies such as remote sensing, GIS, robotics, and advanced diagnostics, which are revolutionizing farm operations and pest/disease management (Lowenberg-DeBoer & Erickson, 2019) [74]. Beyond their immense potential, we critically discuss the implementation complexities and systemic boundaries, including economic viability, the digital divide, policy and regulatory hurdles, and social acceptance (Kremen & Miles, 2012) [65]. Finally, the paper concludes with recommendations for fostering an environment conducive to the widespread adoption of these innovations, emphasizing the need for interdisciplinary collaboration and supportive policy frameworks to build a truly resilient and food-secure future (Foley et al., 2011) [34].
