The way we use land has fundamentally altered the way that many of our soils work. Intensive cultivation and grazing cause massive soil loss, with sediments leaving fields to clog up watercourses. Machinery and animal hooves have also caused many soils to become compacted so that, instead of absorbing water, holding it and slowly letting it go, it runs off hard impermeable surfaces all at once.

Because of intensive farming reliant on inorganic fertilizers, there has also been a widespread reduction in the proportion of soils comprising decaying plant remains the so-called organic matter. Soils depleted in this way hold less water than when they have a healthier proportion of once living material, thereby further altering their ability to ameliorate flood risk.
