Community Capability

Coal mining policies and activities in addition to having a positive impact on state income, job creation and business, also have a negative impact on ecosystems and communities in the mining area. The study was conducted in two mining communities in South Kalimantan using an emic and etic approach to explore community resilience and food insecurity due to ecological changes and the impact of mining policies and activities. Coal mining policies and activities in South Kalimantan causes catastrophic floods, land damage, and crop failure on lowland rice fields that have an impact on potential food insecurity at the household and community level. The pattern of community resilience in the two communities is in the form of social movements as a form of social adaptation, and agricultural land recovery and changing agricultural commodities as a form of ecological adaptation. The process of community resilience in the two communities is at the level of recovery towards a stable community condition, not yet at the transformation stage. Community capability is the most influential factor on the degree of community resilience so that the handling of food insecurity based on community resilience needs to be done by developing strategies to increase community capability.

The Impact

The coal-mining industry plays a vital role towards meeting the energy demands of the people of India. Whether the mining is opencast or underground, however, it affects the environment and ecology of the region. Land is a non-renewable resource and is the main component damaged by mining. In India, exploitation of minerals was carried out in early days with virtually no regard for land protection. Underground mining causes subsidence of strata, mine fires, disturbance of the water-table, topographic disorder, and damage to the land-use pattern.A fact-finding survey was made at an underground coal project of Raniganj Coalfield in Eastern India, to assess the impact of mining on the topsoil, the study area being described. Generally the soils of the local agricultural land are brownish-grey and smooth while those of the ‘danga’ lands are yellowish brown with fine rock materials, the textural quality being, respectively, sandy loam and loamy sand. Field tests such as infiltration rate and field capacity were measured at all the sampling locations, and graphical representation of the infiltration rates are given.Infiltration rates of ‘danga’ land were found to be higher than those of agricultural land, due to their generally coarser texture. Field capacity of agricultural lands were found to range from 17.94 to 21.05%, and of ‘danga’ lands from 12.86 to 14.65%. Wilting coefficients were found to range from 5.31 to 6.75% for agricultural land and from 4.70 to 5.25% for ‘danga’ land. Bulk density, soil pH, conductivity, moisture content, and fertility status of the area, were also studied and the results discussed. Soils are deficient in nutrients. Kharif crops give an average yield of 5.05 quintals (each of 100 kg) per acre (0.405 ha) and Rabi crops only 4.88 quintals per acre. Underground mining activity will create land subsidence and disturb the water-table, finally having a negative impact on the topsoil of the area.

The Impact

This study examines the impact of agricultural land use change into a petroleum mining area to farmers’ socioeconomic conditions around petroleum mining project area in Gayam District of Kabupaten Bojonegoro. The analyses used a mix method, using both quantitative and qualitative approaches. The quantitative approach is used to determine the impact of agricultural land use change on the social and economic aspects with the respondent farmers were supported with a scoring method to determine the condition of socioeconomic vulnerability of farmers, while the qualitative approach carried out through in-depth interviews to some informants who have been affected by the project. The results shows that the presence of the petroleum mining industry has not had a positive impact yet on the farmers’ socioeconomic conditions. By the 700 hectares of agricultural land conversion, the agricultural production capacity of the area tends to decrease, including by the decreasing of the productivity of some agricultural land in a radius of 500 m from the fenceof the mining area as they are affected by the fence’s spotlight. The farmers' income also tends to decrease because of the decreasing of their working hours as the big loss of agricultural land in the area. As a result, many farmers should work outside of the area to search replacement of the arable land. These situations lead to a moderate condition of social and economic vulnerability for the farmers, especially for those who still have sufficient assets to meet the needs of their economic.

To better protect the ecological environment during large scale underground coal mining operations in the northwest of China, the authors have proposed a water-conservation coal mining (WCCM) method. This case study demonstrated the successful application of WCCM in the Yu-Shen mining area. Firstly, by using the analytic hierarchy process (AHP), the influencing factors of WCCM were identified and the identification model with a multilevel structure was developed, to determine the weight of each influencing factor. Based on this, the five maps: overburden thickness contour, stratigraphic structure map, water-rich zoning map of aquifers, aquiclude thickness contour and coal seam thickness contour, were analyzed and determined. This formed the basis for studying WCCM in the mining area. Using the geological conditions of the Yu-Shen mining area, the features of caved zone, water conductive fractured zone (WCFZ) and protective zone were studied. The equations for calculating the height of the “three zones” were proposed. Considering the hydrogeological condition of Yu-Shen mining area, the criteria were put forward to evaluate the impact of coal mining on groundwater, which were then used to determine the distribution of different impact levels. Using strata control theory, the mechanism and applicability of WCCM methods, including height-restricted mining, (partial) backfill mining and narrow strip mining, together with the applicable zone of these methods, were analyzed and identified. Under the guidance of “two zoning” (zoning based on coal mining’s impact level on groundwater and zoning based on applicability of WCCM methods), the WCCM practice was carried out in Yu-Shen mining area. The research findings will provide theoretical and practical instruction for the WCCM in the northwest mining area of China, which is important to reduce the impact of mining on surface and groundwater.

The Impact

This paper studies the impact of food insecurity on civilian–rebel interactions. We argue that food price volatilities affect the incentives of insurgent groups and their subsequent treatment of civilians. The hypotheses developed in this study are empirically evaluated across a battery of statistical models using monthly data from a sample of 112 first administrative districts in sub-Saharan Africa. The results show that increases in food insecurity substantially raise the likelihood of insurgent groups committing violence against civilians and that districts with a higher proportion of agricultural land are at greatest risk of civilian victimization by rebel groups during these episodes of food insecurity. The implications of this analysis suggest that the human impact of food insecurity does not simply relate to nutrition and questions of governance. Food price volatilities also incentivize the use of violence against civilians by non-state actors, which is a pertinent concern of human rights organizations and policymakers.

Abstract This paper investigates the impact of farm-nonfarm diversification (FND) on household income and food expenditure in urban Ghana using propensity score matching (PSM) technique to account for potential selection bias. We find diversified households to be statistically different from undiversified households in terms of household characteristics. Age, gender, educational attainment of the household head, household size, ownership of livestock and agricultural land, and receipt of miscellaneous and rent incomes are positive and significant determinants of FND in urban Ghana. In addition, we find that participation in both farm and nonfarm activities positively and significantly impacts household income and food expenditure. In the light of growing urbanization, with its implications for unemployment, poverty and food insecurity, we recommend diversification among urban households as a means of smoothing income and consumption.

This study focuses globally on the effects of desertification and drought on agricultural lands. Desertification, which shows more its effects from region to region all over the world and particularly on certain continents, contains factors that will disturb the human future. One of these negative factors is the risk of creating food vulnerability by directly damaging agricultural areas. The risk of desertification reducing the quality of human life and threatening other living plants and habitats is a very important issue that should be highlighted by the international system. In this context, the study draws attention to the negative impact of global desertification, as well as the reduction of agricultural and arable land and the risks of declining crop yields. Among other problems caused by desertification, the study emphasizes socio-economic instability due to migration and climate-related conflicts, world hunger and lack of grain and food. In the study, the literature on global desertification, drought and arable agricultural land was searched and selected source information from the literature is included in the study. In addition, the study was supported by maps, graphs, and tables, as well as desertification researches and analyzes. Due to the limitation of the pages, other factors, such as global warming triggering desertification, have not been addressed, and environmental issues, which are directly damaged by desertification other than arable agricultural areas, are excluded from the field of this study.

The Impact

For the purpose of ensuring sustainable development, one of the important factors is to increase labor productivity and minimize the number of workers directly working in the mine. In the context of increasing requirements for underground coal mining, the number of workers tends to decline due to shifting to other types of economy. Therefore, the mechanization investment in coal mining is the inevitable destination, which guarantees the long - term strategic development of the coal mining industry. Although the mechanized mining has obtained several achievements, the annual coal mining output is still not high, specifically reaching 73.8%; 51.3%; 61.4% according to the plan respectively for the years of 2013, 2014 and 2015. A total of mechanized lines has been invested and applied in Vietnam National Coal - Mineral Industries Holding Corporation Limited, but there are only six lines in operation until at this time. For five recent years, when the mining industry has accumulated a lot of experience in using mechanization technology, it is found that the potential factors causing production interruption have resulted in the effectiveness of these longwalls not achieved as expected. Summary of advantages, difficulties, and unsuccessful implementation of mechanization technology in the condition of Quang Ninh mine area has shown a big gap in production organization that should be specifically studying. In this study, the author wants to build a basic background in determining the impact of potential factors conscious of the longwall mechanized.

Background: The massive exploration of coal in Samarinda could lead to various environmental consequences, such as metal contamination of soil, toxic materials and sediments in rivers and air pollution. Scanning and exploring the impact of mining on environmental quality will strategic to develop and carry out rehabilitation on damaged ecosystems and as a preventive and adaptive action of the community in responding the threat of global environmental change.Objective: This paper mainly focused on determining environmental quality based on water and air quality parameters (sulfur dioxide/SO2, Nitrogen dioxide/NO2, Carbon monoxide CO and TSP/dust) also determining community perception about the environment.Methods: Water sample taken from Betapus river (upstream and downstream) and well. Air sample taken around residential in coal mining area. Household survey of 305 respondents conducted in five community neighborhoods in area that affected by mining activities. In general, the air quality parameters such as SO2, NO2, CO and TSP at normal condition.Result: The measurement result of wells water revealed that only the pH (power of hydrogen) at normal condition, while BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), Iron (Fe) exceed the threshold and almost all water sample exceeds the threshold in Manganese (Mn). The results of river quality in pH and COD showed that both in the upstream, midstream and downstream on normal condition, while Fe, COD exceeds the threshold. The BOD in the upper, middle parts of the river exceed the threshold.Conclusion: This study found that there had been anomaly in water environment compounds. These indicate that mining has led to the occurrence of water pollution. Therefore, needs reevaluation analysis of environmental impacts document of the mining companies in Bayur Village. It is also important to treating Mn and Fe of well or river water, especially if the water use for drinking.

<p>This study focuses on the impact of climate change on rainfall-runoff pattern, and to assess the surface runoff and groundwater recharge potential from the intensified rainfall for the effective management of surface and groundwater resources in Tirunelveli city. The rainfall contribution is consistent, dependent, maximum and intensified during the month of November followed by October and December. The intensified rainfall in these months causes a temperature decrease and the climate becomes more and more colder than ever. The indices SPI and DI clear show that there is a change in climatic pattern. Landuse Landcover (LULC) analysis shows that the residential area and mining area is on the increasing trend, Village area is slightly increasing, agricultural area and dense scrub area is on the decreasing trend. The present capacity of the storage tanks available in Tirunelveli city is less than the maximum runoff generated during the month of November. The increase in residential area in LULC reflects the direct linear relation with the population increase of the city. The impact of urbanization leads to LULC change with the loss of agricultural land and water bodies.</p>
