Prickly Pear Cactus : An Excellent Crop to Mitigate Climate Change

Significant variations in global temperatures and weather patterns over time are known as climate change. Although it occurs naturally, human activities—particularly the burning of fossil fuels, deforestation, and industrial processes—are accelerating these changes, which have various detrimental effects on the environment. This review aims to highlight the edapho-climatic requirements of this cactus and the advantages and challenges of its cultivation to mitigate climate change. The prickly pear cactus is a plant with numerous financial and environmental advantages. It needs well-draining, sandy or gravelly soil to avoid root rot and do best in full sun. With a strong tolerance for dryness, they thrive in arid or semi-arid regions with scorching summers and prefer sparing watering. Despite being suited to tropical climates, some species can tolerate freezing temperatures and sporadic frost. Once established, these hardy plants require little care and thrive in nutrient-poor soils, which makes them perfect for xeriscaping or challenging growing environments. Because of its high water use efficiency ratio and low water requirements, prickly pear can be grown in marginally dry and semi-arid areas. The cactus does contribute to the ecological and socioeconomic fight against climate change. For instance, it supports sustainable agriculture, biodiversity preservation, soil restoration, carbon sequestration, and effective water usage. Demarcating dry and semi-arid zones and fostering employment in these areas is beneficial from a socioeconomic standpoint. The prickly pear's traditional cultural heritage supports its current economic function as a crop that can withstand drought. While ecological threats necessitate balanced management, this adaptability promotes sustainable growth. Innovations in bioenergy and value-added goods build on its historical applications, increasing its socioeconomic advantages and, eventually, its worldwide significance.
