In commemoration of the World Soil Day 2019, it is pertinent to note that erosion is recognised as one of the world’s most serious environmental problems. In Nigeria, especially the southeastern part, agricultural productivity, sustainability and management for food security/sustenance has been undermined by the menace of soil erosion. This entails the danger of soil exhaustion, of which accelerated erosion is often only a symptom in Nigeria. Soil erosion, by definition, is a systematic removal of soil, including plant nutrients, from the land surface by the various agents of denudation. This occurs in several parts of Nigeria under different geological, climatic and soil conditions. But the degree of occurrence varies considerably from one part of the country to the other.
Equally varied are the factors responsible for the inception and development of erosion, as well as the types that exist in several parts of the country. It is believed that globally, about 80 per cent of the current degradation of agricultural land is caused by soil erosion. In Northern Nigeria, desertification is one of the major environmental problems while the high torrential rainfall of the southern Nigeria creates the enabling environment for catastrophic soil erosion in the region. Erosion is particularly pronounced and ecologically vulnerable in areas of southeastern Nigeria where population densities and least land per capita ranks among the highest in rural Africa. Dr. Adewale Nafiu, Head of Inspectorate and Education Department of Nigerian Institute of Soil Science (NISS), said the soil in Nigeria is very fragile, hence susceptible to erosion if not handled with care. #StopSoilErosion Nigerian Tribune
