Water diversion and irrigation has allowed humans to grow crops in areas where natural supplies have been limited. A major challenge that exists in these regions has been ________.
salinization of soils high pesticide use low crop diversity high trophic-level efficiency soil erosion
A major challenge that exists in these regions has been salinization of soils. When water is diverted for irrigation, especially in arid and semi-arid regions, the evaporation of water can lead to the accumulation of salts in the soil, which can negatively impact crop growth and soil health.
