The Soil Science Society of Nigeria (SSSN) says at least $27.3 billion is lost annually to salinity-induced soil degradation around the world. The President of SSSN, Prof. Bashiru Raji, represented by his deputy, Prof. Damician Asawalam, said this in Abuja on Sunday at a press briefing organised by the group to mark this year\u2019s World Soil Day (WSD).<\/p>\n
The News Agency of Nigeria (NAN) reports that at its 68th General Assembly in 2013, the United Nations designated Dec. 5 of every year as WSD following the recommendation by the International Union of Soil Science (IUSS) in 2002.<\/p>\n
NAN also reports that the theme for this year\u2019s celebration is \u201cHalt Soil Salinisation, Boost Soil Productivity.\u201d<\/p>\n
Raji described soil salinisation as a major land degradation process that reduces soil fertility and promotes desertification processes in dry land areas. He also described salinity as a situation where salt accumulates in the root zone of crop plants and adversely affects crop growth and yield.<\/p>\n
\u201cSalinity is a growing problem around the globe, especially in soils of the semi-arid and arid regions. Excess salt in the root zone of crops disperses soil aggregates, making it difficult for plant roots to extract water and nutrients from the soil”<\/p>\n
\u201cThe World Bank estimates that soil salinisation due to inappropriate irrigation practices affects about 60 million ha(hectares) of land”<\/p>\n
\u201cSalinisation accounts for 50 per cent of irrigated land in Africa, almost 35% of the agricultural land in Egypt and is a growing problem in India, Pakistan, China, and Central Asia. The annual cost in crop production loss due to salinity induced soil degradation is estimated at USD 27.3 billion” he said.<\/p>\n
He said some states like Nasarawa, Kano and Kebbi among others might experience the problem.<\/p>\n
Raji, who called for urgent action against soil salinisation, said SSSN had joined the rest of the world to also call for conscious actions to limit the expansion of saline soils.<\/p>\n
\u201cWith this theme, soil scientists all over the world are calling on governments, organisations, communities and individuals around the world to commit proactively to maintaining a healthy ecosystem and improving soil health by conscious actions to limit soil salinisation\u201d he said.<\/p>\n
Raji further said that human life is organically linked to the soil, stressing that whatever reduces the productive potential of the soil diminishes human welfare.<\/p>\n
He also said that soil salinisation must be halted to boost soil productivity.<\/p>\n
He advocated the adoption of sustainable farming systems adapted to saline and sodic environments, while encouraging people to avoid unsustainable practices that could lead to soil salinisation.<\/p>\n
Raji, who noted that SSSN had celebrated WSD from its inception in 2014, said the society joins the rest of the global community yearly to celebrate the soil that is our source and sustenance.<\/p>\n
