Abstract: Kutai Kartanegara (Kukar) is an area with quite extensive mining concession. However, Kukar is also the only district in East Kalimantan which experienced rice surplus. Although the amount of rice production is not significant, this condition should be appreciated, because in fact, the official releases shows its surplus is distinguish, compare to other district in East Kalimantan. Problems arise when massive mining operations occurred in those region. Some areas suffered real damage, especially agricultural land around the mining area. Damage is no longer a threat, but it has occurred and persisted. This study try to picture Kukar in the context of farming practices in the crush of mining Activities. There are three villages as observational study area, which are, Jembayan Dalam, Sedulang, and Sarinadi. The author’s findings show that in the three villages, it is interesting to observe and to describe how exactly the problem of agricultural land degradation surrounding the mining existed, and how the community respond to this condition. Jembayan Dalam village and Sedulang suffer severe damages, even the land can no longer being used for farming. However, in Sarinadi, the author found interesting findings since as a farming village, its system and social structure which was built by the community is able to shield themselves from the onslaught of the mining financiers. Keywords: Kutai Kartanegara, agriculture land, miningIntisari: Kutai Kartanegara (Kukar) adalah sebuah wilayah dengan konsesi pertambangannya cukup luas, akan tetapi, Kukar juga satu-satunya kabupaten di Kalimantan Timur yang mengalami surplus beras. Walaupun tidak terlalu besar namun harus diapresiasi, karena faktanya, rilis angka-angka resmi pemerintah menunjukkan itu. Persoalannya, dengan masifnya operasi pertambangan, beberapa wilayah mengalami kerusakan yang cukup serius, khususnya lahan pertanian sekitar pertambangan. Kerusakan bukan lagi ancaman, namun sudah terjadi. Kajian ini akan mencoba melihat Kukar dalam konteks bertani dalam himpitan tambang. Ada tiga desa yang menjadi observasi kajian yakni Desa Jembayan Dalam, Sedulang, dan Sarinadi. Temuan penulis dalam tiga desa ini cukup menarik untuk melihat dan menggambarkan bagaimana sebenarnya persoalan kerusakan lahan pertanian sekitar pertambangan, baik problem maupun respons masyarakat. Desa Jembayan Dalam dan Sedulang mengalami kerusakan yang cukup parah, bahkan lahannya tidak bisa digunakan untuk bertani. Namun di luar itu, Sarinadi sebagai sebuah desa pertanian cukup menarik untuk dilihat karena sistem dan struktur sosial yang dibangun oleh masyarakat mampu membentengi diri dari serbuan para pemodal tambang.

Mining activities are one of the activities that make a positive contribution to community life. However, in addition to making a positive contribution to mining activities, it also has a negative impact on society and the environment. This study was conducted to try to determine the role of benefits, impacts and community trust in influencing community acceptance of mining operations carried out by the company. This research will be carried out using questionnaires and conducting a question and answer directly to the people who live in the area around the mine. The population of this research is the entire community living around the mining area with a sample of about 210 community respondents living around the mining area in Lampung. The renewal of this study is that this study will add diversity and sample criteria compared to previous studies, such as people who live around the mine but also work in related mining companies, environmental activists, and civil servants who work in services that benefit from mining activities. company.

The study investigated the environmental effects of quarry operations in Abeokuta, Ogun state, while it specifically sought to identify corresponding environmental impacts posed in quarry operation and, assess the efforts towards minimizing environmental impacts of their operations. Primary data used for this study was obtained from 100 residents of the community and staffs of the company, randomly chosen and administered with structured questionnaires. Ninety one percent of the respondents noted that environmental problems like land degradation and pollution (including air, water and noise pollution) are associated with mining activities in their respective communities. Air pollution and noise pollution were found to have significant (p < 0.05). Long period (58.0%) of surface mining (71.7%) is prominent in the study area, while it posed some hazards to residents in the study area (84.0%). This includes (degradation of land and vegetation (72.0%), water pollution (44.0%), air pollution (44.0%) and noise pollution (56.0%). Noise and air pollution and governmental intervention in environmental degradation of Mining were found to have significant (p < 0.05) impact on host community as identified by staff of mine and residents. Efforts towards minimizing environmental impacts of quarrying include resettlement and compensation of affected communities (20%). Environmental effects such as land degradation and pollution of various forms (air, ground vibration and noise) in the surrounding communities where the mining activities (quarry operations) are carried out are associated with surface mining activities. It is therefore recommended that government agencies overseeing mining operations revise environmental management policy to ensure that the environmental effects of mining activities are reduced to the barest minimum.

Long-term continuous monitoring of the mining activities in open-pit coal mines is conducive to planning and management of the mining operations. Additionally, this faciliatates assessment on their environmental impact and supervises illegal mining behaviors. Interferometric Synthetic Aperture Radar (InSAR) technology can be effectively applied in the monitoring of open-pit mines where vegetation is sparse and land cover is dominated by bare rock. The main objective of this study is to monitor the mining activities of four open-pit coal mines in the Wucaiwan mining area in China from 2018 to 2020, namely No. 1, No. 2 (containing two mining areas), and No. 3. We use the normalized differential activity index (NDAI) based on the coherence coefficient as an indicator of the mine activity due to its robustness to temporal and spatial decorrelation. After analyzing and removing the decorrelation caused by rain and snow weather, 70 NDAI images in 12-day intervals are obtained from Sentinel-1A InSAR coherence images. Then, the annually-averaged NDAI images are applied to an RGB composite technique (red for 2018, green for 2019, blue for 2020) to express the interannual variation of the mining activities. Points of interest are then selected for NDAI time series analysis. The RGB composite results indicated that No. 1 and 3 open-pit coal mines were continuously mined during the three years; whereas, the two mining areas of No. 2 were mainly active in 2018. The 12-day NDAI time-series graphs of No. 2 open-pit coal mine also indicate that the coal piles located in the coal transferring area of the first mining area were not completely removed until April 2019. It is also seen that the second mining area was decommissioned in November 2018 and became rehabilitated in July 2019. Results were validated using the Sentinel-2A images and related background information confirming the efficiency of the proposed approach for monitoring the mining activity in open-pit mines.

This paper presents a study on assessment of water quality. According to a study, mining activities have a significant impact on water quality (lakes, surface water and groundwater), which has become a major problem globally. Due to mining and exploitation processes, lakes can be formed around these mines. Also, these lakes have been formed around the world and are steadily increasing. The purpose of this study is to watch the quality of water from the area around mining activities. This study refers to the, Groapa Burlacu lake around the mining exploitation Targu Ocna, Romania. This lake was formed on the northern bottle of the massive salt, strongly affected by the underground activities. Sampling for the determination the concentrations of Cl- and NaCl from the studied area was made at different depths (0 m, -5 m, -10 m, -15 m, -20 m, -25 m, -30 m, -35 m -40 m). Besides these concentrations, physical parameters of the water (pH, turbidity, electrical conductivity, dissolved oxygen and temperature) were also measured. To determine the physical parameters in the monitored area, sampling was done from four different points of the area and then put together for analysis. These parameters were measured on site using portable equipment. The data on the analyzed concentrations indicate that at depths of less than 5.0 m, the NaCl concentration values are more than 250 g/L.

Florida has a long history of phosphate-mining, but less is known about how mining affects nutrient exports to coastal waters. Here, we investigated the transport of inorganic and organic forms of nitrogen (N) and phosphorus (P) over 23 sampling events during a wet season (June–September) in primary tributaries and mainstem of Alafia River that drains into the Tampa Bay Estuary. Results showed that a tributary draining the largest phosphate-mining area (South Prong) had less flashy peaks, and nutrients were more evenly exported relative to an adjacent tributary (North Prong), highlighting the effectiveness of the mining reclamation on stream hydrology. Tributaries draining > 10% phosphate-mining area had significantly higher specific conductance (SC), pH, dissolved reactive P (DRP), and total P (TP) than tributaries without phosphate-mining. Further, mean SC, pH, and particulate reactive P were positively correlated with the percent phosphate-mining area. As phosphate-mining occurred in the upper part of the watershed, the SC, pH, DRP, and TP concentrations increased downstream along the mainstem. For example, the upper watershed contributed 91% of TP compared to 59% water discharge to the Alafia River. In contrast to P, the highest concentrations of total N (TN), especially nitrate + nitrite (NOx–N) occurred in agricultural tributaries, where the mean NOx–N was positively correlated with the percent agricultural land. Dissolved organic N was dominant in all streamwaters and showed minor variability across sites. As a result of N depletion and P enrichment, the phosphate-mining tributaries had significantly lower molar ratios of TN:TP and NOx–N:DRP than other tributaries. Bi-weekly monitoring data showed consistent increases in SC and DRP and a decrease in NOx–N at the South Prong tributary (highest phosphate-mining area) throughout the wet season, and different responses of dissolved inorganic nutrients (negative) and particulate nutrients (positive) to water discharge. We conclude that (1) watersheds with active and reclaimed phosphate-mining and agriculture lands are important sources of streamwater P and N, respectively, and (2) elevated P inputs from the phosphate-mining areas altered the N:P ratios in streamwaters of the Alafia River.

Though agricultural landscape biodiversity and ecosystem service (ES) conservation is crucial to sustainability, agricultural land is often underrepresented in ES studies, while cultural ES associated with agricultural land is often limited to aesthetic and tourism recreation value only. This study mapped 7 nonmaterial-intangible cultural ES (NICE) valuations of 34 rural farmers in western Taiwan using the Social Values for Ecosystem Services (SolVES) methodology, to show the effect of farming practices on NICE valuations. However, rather than a direct causal relationship between the environmental characteristics that underpin ES, and respondents’ ES valuations, we found that environmental data is not explanatory enough for causality within a socio-ecological production landscape where one type of land cover type (a micro mosaic of agricultural land cover) predominates. To compensate, we used a place-based approach with Google Maps data to create context-specific data to inform our assessment of NICE valuations. Based on 338 mapped points of 7 NICE valuations distributed among 6 areas within the landscape, we compared 2 groups of farmers and found that farmers’ valuations about their landscape were better understood when accounting for both the landscape’s cultural places and environmental characteristics, rather than environmental characteristics alone. Further, farmers’ experience and knowledge influenced their NICE valuations such that farm areas were found to be sources of multiple NICE benefits demonstrating that farming practices may influence ES valuation in general.
