Salinity crisis in soils stems from global irrigation, climate change and inequitable policies; epigenetics offers one tool among many

Historical salinization events, from the Sumerian irrigation canals to the 19th‑century cotton boom in the American Southwest, reveal a pattern where intensive water use without drainage leads to long‑term soil degradation. These precedents warn that short‑term productivity gains often incur irreversible ecological costs, underscoring the need for preventive infrastructure.
Soil salinization is a symptom of historic and contemporary water mismanagement, climate change, and inequitable agrarian policies, not merely a biological hurdle solvable by epigenetics alone.
Indigenous and farmer‑generated knowledge of halophytes offers time‑tested strategies that can be synergistically combined with molecular tools, provided that governance reforms secure fair water distribution and drainage. Historical precedents warn that without systemic safeguards, technological fixes become temporary band‑aids that mask deeper structural injustices. By integrating cross‑cultural practices, participatory breeding, ecosystem restoration, and climate‑aligned financing, a resilient agricultural future can emerge that honors both scientific innovation and the lived expertise of marginalised communities.
