“…For example, respondents in the present study mention that a landslide occurred in 2008 after prolonged rainfall, and the geological surveys of Uddin et al (2013) and Alam and Islam (2017) have demonstrated that heavy rainfall, deforestation, and channel formation were responsible for landslides and sedimentation in this study area. Different mining activities, particularly "rat-hole mining", sand and stone extraction, and the slash-and-burn method of agriculture practiced in the neighboring hills, also eliminate vegetation cover, promoting soil erosion and subsequent sedimentation, as shown by past research (Dikshit & Dikshit, 2014;Lamare & Singh, 2016;McDuie-Ra & Kikon, 2016;Singh, 2019) that has illustrated how different mining activities in Meghalaya increase soil depletion and subsequent sedimentation.…”

“…Large-scale limestone mining has also taken place around the haor region over the past decade, with both private individuals and cement companies involved in this mining, depending on their capacity. In most cases, the limestone is quarried in open-pit mines, where miners remove vegetation from the hills, then drill and blast the rock, after which the limestone is excavated and broken into smaller pieces that are transported to the cement plant (Lamare & Singh, 2016). Limestone production in the Jaintia and Khasi hill regions of Meghalaya between 2008 and 2015 totaled c. 38 MT (Government of Meghalaya: Department of Mining and Geology, 2022).…”

“…At present, >7,000 km 2 of land in Meghalaya has been cultivated using this method, and the percentage use of this method is increasing (Yadav et al, 2012). Similarly, various studies in Bangladesh and India have shown that exploitation of swamps and rainforests, together with various unplanned and unsustainable methods of cultivating crops on hillsides, are major causes of soil erosion and siltation of wetlands (Hassan et al, 2005;Lamare & Singh, 2016;Sarma & Barik, 2011). For example, in Hail Haor, Bangladesh, Uddin et al (2013) found that the cultivation of various citrus fruits and pineapples accelerated soil erosion because farmers traditionally grew these fruits in rows aligned with the slope of the land, which promoted erosion.…”

Introduction and BackgroundThe haor landscape (Figure 1) comprises a large, shallow tectonic depression in the northeastern part of Bangladesh that becomes inundated to a depth of 5 m or more during the monsoonal annual rainy season. Haor covers an area of approximately 2 million hectares (19,998 km 2 ) and supports a population of 19.37 million people (Chakraborty et al., 2021;Kamal et al., 2018). The haor basin is actively subsiding, and its hydrological, topographical, geomorphological, and socioeconomic features are distinctive as compared to other parts of Bangladesh (Chakraborty, Mondal, et al., 2012;IUCN, 2015). The geology of the haor basin consists of 13-20 km thick alluvial and deltaic deposits underlain by gneisses and granites, and the basin is bounded by the Shillong Plateau to the north (Figure 1), the Indo-Burman Range to the east, and the Indian Shield to the west. Non-calcareous, non-saline gray alluvium and acidic, alkaline clays are the most common soils within the basin (DBHWD, 2017), which is predominantly topographically flat but possesses some low hills that are covered with rainforest, tea and rubber plantations. The haor is very close to the towns of Cherrapunji (Figure 1) and Mawsynram, which are considered to be the rainiest places in the world, with an average annual rainfall of 11,755 mm and an average rainfall of 1,700 and 7,400 mm in the pre-and post-monsoon seasons, respectively (Basher et al., 2018;Rahman et al., 2020). As a result, the haor region receives significant runoff from 23 small transboundary rivers, including the Surma-Baulai, Kalni-Kushiyara, and Kangsa-Dhanu rivers, which originate in the hill regions of neighboring India. Seventy percent of the total catchment area of these rivers depends on three Indian States: Meghalaya, Assam, and Tripura (CEGIS, 2012). This abundant runoff enables the annual flooding of the haor region (Figure 2) to depths of 5-7 m, and much of the area is thus characterized by regular yearly inundation.

“…The main causes listed were deforestation, fire, agricultural expansion, construction, overgrazing, urbanization, and unscientific exploitation of forests. The results of Lamare and Singh [87,88] also indicated that extraction of limestone and the open dumping of overburden from adjacent mines have a negative impact on soil, water, and air quality, as well as on forest health and water availability, which eventually affects the flora and fauna of the study area.…”

Diabetes mellitus is the world’s major public health issue and has been dubbed the “Silent Epidemic” of the twenty-first century. This is the first ethnobotanical exploration to document the folk medicinal usage of plants with therapeutic antidiabetic properties by the Pnar tribes of East Jaintia Hills, Meghalaya. Forty-one practitioners and knowledgeable people were interviewed using a semi-structured questionnaire. Field inventories were then conducted to collect plant material for botanical identification. In this study, 51 plant species belonging to 34 families and 45 genera have been identified. This study indicates that herbs were the most prevalent living form used (N = 23) for the treatment. Rhus semialata is one of the most frequently cited medicinal plants, with a Relative Frequency of Citation (RFC) of 0.73. Moreover, the details about the phytochemicals and the pharmacological activities of identified plant species have been reviewed and disclosed. Agricultural expansion, deforestation, urbanization, and unscientific exploitation of the forests were cited most when respondents were asked about the threat to medicinal plants. Of the 51 plant species, 12 are included on the IUCN Red List. Therefore, this documentation of indigenous plants would create awareness about the importance of medicinal plants and their conservation and protection.

“…The habitat destruction and fragmentation severely reduce the grassland's ability to provide ecosystem services with severe impacts on the native ora and fauna surrounding the quarries (Sala et al, 2010). For example, in areas affected, successional processes cannot proceed and are stuck at the early stages of colonization, mainly due to thin topsoil, without seed banks and rootstocks (Flavenot et al, 2015;Lamare & Singh, 2016).…”

Quarrying generates signi cant changes in the grasslands, by reducing ecological functions, reducing connectivity, impairing biodiversity, and degrading soil. Unlike other forms of destruction such as agriculture or urbanization, mining is characterized by eliminating soil and exposing the bedrock, facilitating groundwater contamination processes. Quarrying in Pampean grassland has been expanding for a century and little is known about the extent and distribution of quarries over the native environment.In this work, we analyze the spatiotemporal variation of quarrying activity on the Highland grassland in the Tandilia mountains of Argentina. Based on Landsat 5, 7, and 8 satellite imagery, from 1996 to 2022, and using QGIS software, we identi ed the location and extension of quarries, and we analyzed their change through time. Quarries covered 6428 ha, which was originally part of the Pampean grassland.The number of open quarries increased by 129%, from 69 in 1996 to 158 in 2022, and the area used for this activity increased by 172%, with a greater expansion being detected in the last ten years. At least 87 quarries were abandoned in 2022. Quarries are often abandoned without any kind of remediation, leading to further ecosystem deterioration. The current extension of quarrying activity (active and abandoned quarries) reduced the connectivity and a signi cant area (5.2%) of the Highland grassland of the Tandilia Mountains. Grassland conservation planning should include quarrying as a signi cant threat, and management actions must be considered to reduce its impact.
