Agroforestry is essential for enhancing water quality compromised by human activities including chemical compounds, such as nitrogen (N) and phosphorus (P) in modern agricultural practices (MAPs). This cutting-edge study seeks to reevaluate the impact of agroforestry systems (AFS) on climate change, soil preservation, and groundwater quality. This review is new because it shows that agroforestry systems (AFS) may make water cleaner, keep nutrients from being lost, and help the soil's biological, chemical, and physical qualities. It is important to note that the slope gradient, soil types, topography, and other surface geological elements might change a watershed that is mostly made up of agroforestry lands. Also, human activities, like farming, may make the water quality in basins with a lot of AFS area worse. This review is also new since it shows how AFS may be used to clean up polluted soils by lowering levels of aluminum (Al), mercury (Hg), and cadmium (Cd), among other things. So, AFS may be used to clean up water, fight climate change, adapt to climate change, and protect soil. Additional study is necessary to examine the role of AFS in soil integrity.
