These findings highlight the importance of increasing the size of harvest areas and production to support the growth of the agricultural sector, which is one of the largest contributors to GDP. one of the largest contributors to GDP. Key challenges include climate change and price fluctuations, which require adaptive policies as well as technological support. This research provides insights for the development of strategies that focus on on the sustainability of the agricultural sector to strengthen national food security.
