“…Kandrika and Dwivedi (2013) extracted a digital elevation model from the high‐resolution (2.5 m) Cartosat‐I PAN stereo images for reclamative grouping of badlands in respect of gully depth and width in the Mahoba district in Uttar Pradesh. Pani (2012) and Tagore et al (2021) classified LISS III (23.5 m) scenes of the Morena district of Madhya Pradesh in conjunction with visual assessment of Survey of India topographical maps (1:50,000 scale) for badlands delineation. In the Bhind district in Madhya Pradesh, Dwivedi and Ramana (2003) used the same data, but emphasized on the extraction of relief information from the topographical maps in order to obtain badlands’ depth classes.…”

Mapping of Land Degradation Vulnerability in the Semi-Arid Watershed of Rajasthan, India

Global soils are under extreme pressure from various threats due to population expansion, economic development, and climate change. Mapping of land degradation vulnerability (LDV) using geospatial techniques play a significant role and has great importance, especially in semi-arid climates for the management of natural resources in a sustainable manner. The present study was conducted to assess the spatial distribution of land degradation hotspots based on some important parameters such as land use/land cover (LULC), Normalized Difference Vegetation Index (NDVI), terrain characteristics (Topographic Wetness Index and Multi-Resolution Index of Valley Bottom Flatness), climatic parameters (land surface temperature and mean annual rainfall), and pedological attributes (soil texture and soil organic carbon) by using Analytical Hierarchical Process (AHP) and GIS techniques in the semi-arid region of the Bundi district, Rajasthan, India. Land surface temperature (LST) and NDVI products were derived from time-series Moderate-Resolution Imaging Spectroradiometer (MODIS) datasets, rainfall data products from Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS), terrain characteristics from Shuttle Radar Topography Mission (SRTM), LULC from Landsat 9, and pedological variables from legacy soil datasets. Weights derived for thematic layers from the AHP in the studied area were as follows: LULC (0.38) > NDVI (0.23) > ST (0.15) > LST (0.08) > TWI (0.06) > MAR (0.05) > SOC (0.03) > MRVBF (0.02). The consistency ratio (CR) for all studied parameters was <0.10, indicating the high accuracy of the AHP. The results show that about 20.52% and 23.54% of study area was under moderate and high to very high vulnerability of land degradation, respectively. Validation of LDV zones with the help of ultra-high-resolution Google Earth imageries indicates good agreement with the model outputs. The research aids in a better understanding of the influence of land degradation on long-term land management and development at the watershed level.

“…Changes made during this process were purely cosmetic and no alterations to the science or conclusions have been made since acceptance of the article. approaches including data sources, definitions, classification, scale, and so on resulted in diverse values of degraded lands in India (Tagore et al 2021). Therefore, the Indian Space Research Organization, Ministry of Environment, Forest and Climate Change, and Arid Forest Research Institute, jointly reported causes of land degradation and its distribution using digital Indian Remote Sensing Advanced Wide Field Sensor (IRS AWiFS) data of -2005and 2011-2013(GOI 2016.…”

The land in India is under severe threat of degradation. According to the 2016 Atlas of Land Degradation and Desertification, 29.3% of the total geographical area of India has been degraded or converted to deserts. To maximize ecological and economical benefits through the restoration of degraded ecosystems, India became a party to Bonn Challenge and United Nations Decade on Ecosystem Restoration 2021–2030 and has pledged to restore 26 million hectares of degraded land by 2030 during conference of parties 14 of United Nations Convention to Combat Desertification at Delhi. In Paris Agreement 2015, India has also pledged to increase forest tree cover through reforestation and afforestation initiatives, bringing degraded ecosystems under restoration, and sequester additional 2.5–3 billion tonnes of CO2 by 2030. These positive commitments are encouraging, but developing effective strategies for implementation of ecological restoration on the ground we need to understand (1) distribution of differently degraded ecosystems; (2) the status of scientific thoughtfulness and practices of restoration; and (3) review of empirical studies those can scientifically guide to pave the road to land degradation neutrality in India. Therefore, this study briefs about the distribution of degraded ecosystems, development of the science of restoration ecology, and its understanding and provide a synthesis of appropriate case studies on different degraded ecosystems, including forests, mined areas, and degraded and/or abandoned lands.
