Short summary
Land use-land cover, agricultural nutrients, and irrigation impact the benefits that humans receive from landscapes (e.g., water quality, food production). We present here the methods for developing historical (1938–2020) maps of all three of these critical drivers, which can be used to analyze the immense changes as agriculture has intensified with more nutrient inputs and irrigation and less crop diversity. The data can also be used to drive models including those that estimate water quality.
