Human activities that help to keep the natural resources of Earth available and clear of pollution. Soil salinization (salinisation) is the increase of salt concentration in soil and is, in most cases, caused by dissolved salts in the water supply. Due to climate change, sea levels are rising, which further accelerates the process of salinization. Salinization reduces biodiversity in rivers or fresh-water lakes, shortening aquatic populations solely to salt-tolerant species. The regulation of plant cell wall organisation under salt stress. Apart from visual estimation, there are more reliable methods to measure soil salinity, e.g., to assess the earths electric conductivity with specific devices.

Water is then pulled into the soil and unavailable to the plant, causing dehydration and loss of crops. The analysis suggested that an inclusive feedback-supported simulation model for managing soil salinization should be considered in future research as the existing models scarcely considered some vital aspects of the problem.
