The rapid growth of the global population coupled with the challenges posed by climate change and environmental degradation has intensified the need for sustainable agricultural practices. Genomic innovations in plant breeding and genetic advancements offer promising solutions to these challenges by enhancing crop resilience, productivity, and nutritional value while reducing the environmental footprint of farming. This article explores the role of key genomic tools such as genomic selection, CRISPR-Cas9 gene editing, marker-assisted selection, and polyploidy in advancing sustainable agriculture. These technologies enable the development of drought-tolerant, pest-resistant, high-yielding, and nutritionally enhanced crops, contributing to food security and environmental sustainability. However, challenges related to cost, accessibility, and ethical considerations remain. The article concludes that continued research and responsible application of genomic tools are essential for shaping the future of agriculture.
