“…Rising aquifer levels due to over-irrigation are contributing to soil-salinization across the Rufiji River Basin [98] and other agricultural areas [99,100]. Moreover, groundwater is increasingly polluted as a result of human activities, notably by nitrates from poor sanitation and fertilizer use [101][102][103].…”

“…Consequently, addressing the challenges facing food production, including soil salinization has become a major focus in recent decades (29,30). In Tanzania, the alarming condition of salt-affected soils has been reported by several researchers (31)(32)(33). Kashenge-Killenga et al (31) found that 7-15% of rice irrigation schemes were affected by salts, and about 2-10% of rice fields were abandoned.…”

“…Alteration of these successive electrons transfers electrons to oxygen molecules which leads to the formation of reactive oxidative species that normally act as signaling molecules and may induce oxidative damage at high concentrations and reduce the rate of photosynthesis [13]. Saline soils are estimated to cover about 5-10 % of the world's arable land [9]. However, 20% of the world's irrigated land is adversely influenced by salinity and the problem is further increasing because of poor drainage and climate changes [22], [9].…”

“…Saline soils are estimated to cover about 5-10 % of the world's arable land [9]. However, 20% of the world's irrigated land is adversely influenced by salinity and the problem is further increasing because of poor drainage and climate changes [22], [9]. In Tanzania, the challenge is increasing rapidly as reported by FAO in 2003 about 3.5 million hectares are prone to salinity covering both the semi-arid, low land and irrigated and non-irrigated areas [14].…”
