Cash/valuable crop production on polluted land

Earth's land degradation and contamination occur by releasing metal(loid)s and organic pollutants (benzene, asbestos, paints, plastics, crude oil, pesticides, herbicides, etc.) due to rapid industrialization, urbanization, mining, waste disposal, and agricultural practice. All these lead to loss, deterioration, and fragmentation of habitat, deforestation, and desertification of lands and pose a serious threat to human health. Sustainable land management addresses phytoremediation and efficient bioeconomy of valuable crops on polluted lands. Cash crops are plant species that are planted to make a profit and they are used for biofuel, fibers, dye, essential oils, timber/firewood, and floriculture. Cash crops can be used for phytoremediation of polluted lands because they tolerate drought/extreme temperatures/salinity/toxicity and achieve ecosystem stability, resilience, and economic benefit. Phytomanagement of cash crops on polluted lands includes phytoremediation and revitalization of contaminated sites, high yield harvest and efficient use of biomass, increase in biodiversity, an increase of organic carbon, low production cost, cooperation between science, government, and farmers with public transparency, market certification, and high ethical standards. Industrially driven agriculture can be changed through the “restoration economy” and “regenerative agriculture practice” presenting a new challenge and alternative platforms for advance practice and a sustainable bio-economy of degraded lands worldwide.
