Marginal lands, often characterized by low fertility, poor water availability, or extreme climatic conditions, present significant challenges to conventional farming practices. Research into crops that can thrive in these environments is essential for improving agricultural productivity and land use efficiency. Scientists are developing drought-tolerant, salt-resistant, and nitrogen-efficient crops that can flourish in harsh conditions. These crops can help transform previously unusable lands into productive agricultural areas, boosting food production in regions where resources are limited. By enhancing crop resilience to environmental stressors, this research ensures that farming remains viable in marginal areas, contributing to food security and sustainable land management.
