    2014-6-16  8 Aromolaran (2012) studied the effects of sand mining activities of rural people on agricultural land in Agraiancommunities of Ogun state in Nigeria. His work revealed that mining of sand and gravel on agricultural land is one of the alternative livelihood activities of the V rural people in Nigeria and is now becoming an II environmental issue. He equally noticed that there is s increase in demand for sand for construction and other purpose as communities grow because the construction at present requires less wood and more concrete, which sprout a demand for low-cost sand. Mining of sand on farms and fallow agricultural land is becoming common and this is having noticeable impacts on the soil) structure, vegetation and local wildlife in the rural areas. H He noticed that sand mining is widespread, highly (unregulated, uncontrolled and is being carried out at an alarming rate.
