“…This article further provides insight on an integrated climate‐sensitive restoration framework that recognizes the local participation in mapping degraded lands, identification of species that can support socio‐economic needs of the region as well as confronting the erratic climate pattern. Eco‐restoration successes for mines in India have a good history (Rajdeep et al, 2011; Soni & Gairola, 2011; Ahirwal & Pandey, 2021; Kumar et al, 2021). GIS tools have been a consistent and successful indicator in identification of successes of reclamation projects around India and the world (Karan et al, 2016).…”

The present study attempts to understand land use land cover change dynamics in an area subjected to opencast and underground coal mining for the last few decades in Kotma Coalmines of Anuppur District in Madhya Pradesh, India through geospatial techniques. Land use and land cover (LULC) change detection analysis was performed digitally classifying LANDSAT-5 (2001) as well as LANDSAT-8 (2020) satellite data using a maximum likelihood algorithm. Results revealed that area under dense native vegetation decreased drastically (by 13.74 km 2 ) with the gradual and consistent expansion in the activities of coal mines which showed the highest increase in area over time (15.84 km 2 ). Bivariate regression analysis showed the positive empirical relationships between vegetation indices and soil physico-chemical parameters. Studies suggested that soil and vegetation is degraded over the large mining areas consistently over a long time period. Despite the continuous reforestation activities on mined areas, the decline area under dense vegetation and sparse vegetation over the twenty-year time-scale indicates that the reclamation activities are still in its infancy.A land degradation vulnerability Index (LDVI) map was generated to understand the extent of decadal land degradation trends and it shows that 8.60% of the area is highly vulnerable to degradation. The land degradation index (LDI) inputs will help the planners to develop alternate strategies to tackle vulnerability zones for safe mining. Monthly estimation of various meteorological parameters was also recorded to generate heat plots for the period 2001-2020. The study concludes that monitoring and assessment of fragile ecosystems are indispensable for holistic environmental management.coal mining, decadal changes, heat plot, land degradation vulnerability index, land use land cover | INTRODUCTIONThe Anthropocene is a time of great risk for humanity due to emerging as well as rapidly evolving environmental consequences (Crutzen, 2002;Kareiva, 2014;Keys et al., 2019).

“…Compared to the previous estimate in 2017, the country’s carbon stock has increased by 42.6 Mt [ 35 ]. It also gives around 40 t of biomass ha −1 , which projected its potentiality towards the generation of bioenergy and environmental management [ 30 , 38 ].…”

“…Bamboo is best known for its three distinct features: flowering, rapid growth, and increased physical and mechanical characteristics [ 29 ]. Bamboo has a remarkable ability to store and capture carbon (C) and a high nitrogen (N 2 ) fixation ability, making it very appealing to biologists [ 30 ]. Humans have used bamboo for thousands of years, and it is used in India as a fiber, firewood, and food source.…”

Increasing population, industrialization, and economic growth cause several adverse impacts on the existing environment and living being. Therefore, rising pollutants load and their mitigation strategies, as well as achieving energy requirements while reducing reliance on fossil fuels are the key areas, which needs significant consideration for sustainable environment. Since India has considerable biomass resources, bioenergy is a significant part of the country’s energy policy. However, the selection of feedstock is a crucial step in bioenergy production that could produce raw material without compromising food reserve along with the sustainable environment. Higher growth capacity of bamboo species makes them a suitable lignocellulosic substrate for the production of high-value greener products such as fuels, chemicals, and biomaterials as well as an appropriate candidate for eco-restoration of degraded land. In that context, the current review discusses the multidimensional applications of bamboo species in India. The bioenergy potency of bamboo and probability of aligning its production, cultivation, and operation with economic and social development agendas are also addressed, making it an exceptional crop in India. Additionally, its fast growth, perennial root systems, and capability to restore degraded land make it an essential part of ecological restoration. Furthermore, this review explores additional benefits of bamboo plantation on the environment, economy, and society along with future research prospects.

Ecological restoration of fly‐ash disposal areas: Challenges and opportunities

Fly-ash (FA) is a by-product or residue that is produced during the combustion of coal for energy production in thermal power plants. The huge amount of FA generation is a global problem; and coal power generators still can find no safe and sustainable approach to FA disposal. FA dumps not only create air, water, and soil pollution but also pose a noxious impact on human health by introducing toxins in the food chain through biomagnification. A non-food vegetation cover can help to mitigate FA dump-related environmental health issues. However, alkaline pH, toxic metals, lack of soil microbes, and pozzolanic properties of FA limit plant growth. In this regard, ecological restoration of FA dumps through phytoremediation should be a holistic approach. This review focuses on the role of naturally occurring plants, tree plantation, and microbial inoculation in the ecological restoration of FA dumps and their role in the physicochemical changes of FA substrate. Application of organic material has been proved to help establish vegetation cover on FA dumps as they provide essential nutrients for plant and microbial growth. Morphological, physiological, and antioxidant responses of plants grown on FA dumps are also discussed in this study in detail. Overall, this review summarises the different comprehensive approaches of FA dump restoration and compiles ways to convert barren FA dumps into useful sites for deriving bioeconomy with phytoproducts. The outcomes of this study should be beneficial helping identify site-specific ecorestoration of FA dumps through an integrated approach.
