Technical Report of Project entitled Study on Mining Affected Areas and its Impact on Livelihood Meghalaya- Community Led Landscape Management Project Meghalaya Basin Management Agency Shillong 2019 Prof. O. P. Singh Principal Investigator/Consultant Department of Environmental Studies North-Eastern Hill University Shillong- 793022 Meghalaya Project Number: P 157836 Contract Number: MBMA/CLLMP/PP/Mining/46/2017 Preface The indiscriminate and unscientific mining and absence of post mining treatment and management of mined areas have made the fragile ecosystems of Meghalaya more vulnerable to environmental degradation and depletion of natural resources. As a consequence, the natural resources such as soil, water, forest and forest products, biodiversity etc. have been severely affected both in terms of their quality and quantity in the mining areas of the state. The traditional livelihood options linked to these resources have also been found affected. The information on effects of coal, limestone, sand mining etc. on land, water, forest resources and the community are fragmentary and thus needed consolidation with recent data. The meagre information available on the effect of mining on human health, natural resources with special emphasis on soil, water and biodiversity, livelihood of the people with particular reference to agriculture including horticulture, livestock, aquaculture and fishery are scattered, hence needed compilation. Such information is essential to strengthen the community led natural resource management practices in order to facilitate community led planning coupled with technical inputs and funding broadly in the areas of forest, water and soil in Meghalaya. Hence, the need was felt to compile available information in order to identify the drivers of degradation and also for promoting activities towards conservation of forest, soil and water resources with reference to sustainable livelihood. Hence, the project entitled ‗Study on Mining Affected Areas and its Impact on Livelihood‘ under the Meghalaya-Community Led Landscape Management Project (CLLMP), Meghalaya Basin Development Authority, Shillong was undertaken with the major objectives of strengthening community led natural resource management of mining affected area of Meghalaya During the study information was collected and compiled based on field visits, discussion with the stakeholders, questionnaire survey, laboratory analyses and consultation with experts. Local bodies, research and voluntary organizations, communities, Green Volunteers, NGO representatives etc. were also consulted. Based on the information generated and gathered from primary and secondary sources this report has been prepared. The information included give a generalized view of the state of environment of mining areas of Meghalaya based on scientific studies and peoples‘ perception on mining and its impact on natural resources and livelihood based on questionnaire survey. Measures to mitigate the adverse impacts of mining activity on environmental components and livelihood of the people have also been suggested. Options to restore and rehabilitate the mining affected areas are also included for improvement of livelihood options and life of the affected people. It is expected that information included in this report will help in strengthening the community led natural resource planning and management of different landscapes in Meghalaya.
