“…Increase in demand for sand, gravel and stone implies an increase in sand/gravel mining activities at the detriment of agricultural activities and a resultant reduction in food security of people in urban and peri-urban areas. A similar finding was reported by Mngeni et al (2016) in their study of the effects of sand mining on rural communities of the wild coast of South Africa. They reported that sand mining carried out in an unguided manner portends negative consequences for land in the rural communities.…”

There is virtually no information on the effects of artisanal sand mining on peri-urban agriculture in Nigeria in general and Osun State in particular. This study assessed the effects of sand mining on peri-urban agriculture in Ife East and Ife Central Local Government Areas of Osun State during 2015-2019. In effect, the study sought to identify and explain the rate and extent of changes in land uses in the study area, evaluate the level of encroachment of sand mining activities into other land use classifications, and examine socioeconomic factors that determined parting of land for sand mining by landowners in the study area between 2015 and 2019. Data were generated from both primary and secondary sources. Multi-stage sampling technique was used to collect primary data from 60 landowners, 30 cultivators and 30 residents giving a total of 120 respondents using structured questionnaire. Mean ages of landowners, farmers and residents were 67.9 years, 39.6 years and 47.3 years respectively. Majority (68.3%) of landowners had no formal education, while majority (73.3%) and (90%) of farmers and residents had formal education. Majority (68.3%) of landowners were farmers while majority (66.7%) and (76.7%) of farmers and residents were employees of governments. Majority (93.3%) of landowners were males, 100% of farmers were males. Cultivated land area decreased from 48% to 23.2% (–24.8%), built-up area increased from 37.3% to 41.8% (4.5%) while sand-mined area substantially increased from 14.6% to 35% (20.4%). Parting of land for sand mining increased with increasing age, household size and primary occupation being farming while parting of land for sand mining decreased with higher level of education. It is therefore recommended that all levels of government in the country should embark on close monitoring of land use to prevent frequent occurrence of land and environmental degradation. Additionally, Land Use Act of 1978 should be reviewed by bringing all stakeholders together to deliberate on how to prevent multiple land ownership and conflicts.

Global sand demand due to infrastructure construction has intensified sand mining activities in many rivers, with current rates of sand extraction exceeding natural replenishment. This has created many environmental problems, particularly concerning riverbank stability, which adversely affects the livelihoods of people in the Vietnamese Mekong Delta (VMD). However, sand mining’s social impacts in the region remain inadequately understood. Here we assess locals’ perception of sand mining activities in the VMD and its impacts on riverbank erosion. Residents living along the Bassac River, a hotspot of sand mining, were interviewed. Our results showed that while sand mining is perceived as destructive to the environment, few were aware of its role in worsening riverbank erosion. Only residents directly affected by riverbank collapse were aware of the implications of sand mining and its negative effect on bank stability, as they seem to have actively sought clarification. Our findings highlight the need for greater awareness and understanding among the locals regarding sand mining’s impact on riverbank stability.

“…Surface mining is an activity that results in the destruction of the natural topography and a severe disturbance of soil (e.g. Lubke & Avis, 1999;Rate et al, 2004;Shrestha & Lal, 2006;Chaudhuri et al, 2013;Pallavicini et al, 2013;Pitchaiah, 2017;Gao et al, 2020) which in turn has social, economic and environmental impacts (Haigh et al, 2013;Martín-Moreno et al, 2013;Khan & Suzic, 2015;Mngeni et al, 2017a). Mineral sand mining, during which heavy minerals are extracted from coastal sand dunes, is one form of surface mining that is common in many places around the world (Moore, 2011;Gavriletea, 2017).…”

Availability of Residual and/or Applied Inorganic Phosphorus for Sugarcane Uptake and Growth in a Post-Mined Reconstituted Soil

Mineral sands mining is worldwide an environmental issue and also at the Hillendale mine in KwaZulu-Natal, South Africa. The post-mined soil is to be rehabilitated to sugarcane cropping. One of the concerns with the post-mined soil which is reconstituted with a 70:30 mixture of sand: slimes (silt-plus-clay fraction), is its low phosphorus (P) status, which could be limiting for optimum sugarcane production. A field experiment was conducted on a reconstituted soil at Hillendale to establish the availability of either residual or applied inorganic P to the plant and first ratoon sugarcane crop. Four treatments were evaluated including those where P fertilizer was omitted, applied at half the recommended rate or introduced equal to the recommended rate according to chemical analysis of the soil. In the fourth treatment, no fertilizer was applied at all, whereas nitrogen (N) and potassium (K) were added at recommended rates in the first three treatments. Phosphorus application had a significant effect on sugarcane fractional light interception and aboveground biomass yield of the plant and first ratoon crops, and stalk length and diameter of the first ratoon crop. Pol, brix, purity and fibre content and tiller number were not affected by P application. The application of P increased the foliar N, P, K, calcium (Ca), magnesium (Mg) and sulphur (S) contents of both crops. However, foliar N, P and K were deficient in the first ratoon crop even in the case where fertilizer was applied at the recommended rates, which could have been because of waterlogging. The possible effect of waterlogging on P uptake needs to be addressed in future studies in this reconstituted soil.
