Genetic Engineering for Drought Resistance in Crops: A Pathway to Food Security

Abstract

Drought presents a formidable challenge to global food security, particularly in the context of climate change. Genetic engineering emerges as a promising solution to develop drought-resistant crops capable of withstanding water scarcity while maintaining productivity. This paper provides an overview of the current state of genetic engineering technologies aimed at enhancing drought tolerance in crops and their implications for food security. Understanding the physiological and molecular responses of plants to drought stress is essential for identifying target genes and pathways for genetic manipulation. Various genetic engineering approaches, including transgenic techniques, marker-assisted selection, genome editing, and synthetic biology, offer versatile tools for enhancing drought resilience in crops. Despite their potential benefits, the adoption of genetically engineered drought-resistant crops faces regulatory, socio-economic, and environmental challenges. Harmonizing regulatory frameworks, addressing public concerns, and promoting equitable access to technology are essential for realizing the full potential of genetic engineering in agriculture. Looking ahead, advancements in genome editing technologies, integration of omics approaches, and climate-resilient breeding programs hold promise for developing tailored drought tolerance traits in crops. By fostering interdisciplinary collaboration and innovation, genetic engineering offers a pathway to building more resilient and sustainable food systems capable of ensuring food security for future generations in a changing climate.
