Introduction Salt-affected soils are a global issue, affecting 1 billion hectares worldwide, including 80 million in Africa. In sub-Saharan Africa (SSA), these originate from marine, geological, and hydrogeological sources, as well human activities arid climatic condition-induced salinization. Methods This systematic review, conducted using the PRISMA framework, provides an in-depth analysis of salt-affected SSA 1970 to present. It highlights historical trends emerging patterns salinization region. Results Discussion The review estimates that 65.6 land salt-affected, with key hotspots coastal zones, river deltas like Nile Delta, areas intensive irrigation. Generally, Eastern Africa, Southwest West African inland Delta Lake Chad Basin most vulnerable. Ethiopia is affected country, 11 affected, primarily due poor irrigation drainage infrastructure. study also research gaps, revealing countries such Senegal, Tanzania, Kenya better studied than Mali. found available heavily rely on FAO report 1988, based Solonchaks (saline soils) Solonetz (sodic soils). was produced Soil Map World at scale 1:5,000,000, which created between 1981. Due its coarse resolution, high generalization, environmental changes have occurred over decades, it may be considered outdated, presenting need for updated data. creation digital fine-scale maps by integrating field laboratory data, soil data World, HWSD, WoSIS databases remote sensing highly suggested this regard. Saline agriculture utilizing brackish water salt-tolerant crops, improved salinity detection monitoring, practices, application gypsum organic amendments (e.g., pressmud), phytoremediation halophytes recommended. projects efforts could double agriculturally yields areas, improving food security economic resilience.

Environmental research has become increasingly important due to the human impact on ecosystems, with a particular need study how different drainage systems affect water quality. Improperly functioning can result in significant losses of biogenic substances, soil erosion, eutrophication, and declining biological capacity. This addresses existing knowledge gap by consolidating critically analyzing recent scientific literature controlled free draining types over forty years (1986–2024) using Web Science Scopus databases. The objective this systematic review is collect summarize information various systems, their advantages disadvantages, effect environmental A 144 selected papers from past four decades indicates that installation, use, upgrading remains subject extensive debate within community, particularly regarding leaching substances into open bodies. results obtained indicate nitrogen (N) (found 54 papers) phosphorus (P) 48 are primary elements affecting aquatic ecosystems eutrophication processes. Also, compared mathematical tools 42 articles), there lack application AI for modeling predicting quality climate change. Consequently, ongoing area crucial, offering researchers, practitioners, wild society insights overall environment, opportunities improvement unexplored directions systems.
