A seamless vegetation type map of India (scale 1: 50,000) prepared using medium-resolution IRS LISS-III images is presented. The map was created using an on-screen visual interpretation technique and has an accuracy of 90%, as assessed using 15,565 ground control points. India has hitherto been using potential vegetation/forest type map prepared by Champion and Seth in 1968. We characterized and mapped further the vegetation type distribution in the country in terms of occurrence and distribution, area occupancy, percentage of protected area (PA) covered by each vegetation type, range of elevation, mean annual temperature and precipitation over the past 100 years. A remote sensing-amenable hierarchical classification scheme that accommodates natural and semi-natural systems was conceptualized, and the natural vegetation was classified into forests, scrub/shrub lands and grasslands on the basis of extent of vegetation cover. We discuss the distribution and potential utility of the vegetation type map in a broad range of ecological, climatic and conservation applications from global, national and local perspectives. Weused 15,565 ground control points to assess the accuracy of products available globally (i.e., GlobCover, Holdridge’s life zone map and potential natural vegetation (PNV) maps). Hence we recommend that the map prepared herein be used widely. This vegetation type map is the most comprehensive one developed for India so far. It was prepared using 23.5m seasonal satellite remote sensing data, field samples and information relating to the biogeography, climate and soil. The digital map is now available through a web portal (http://bis.iirs.gov.in).

Water quality of Himalayan rivers has been steadily deteriorating over several decades due to anthropogenic activities, dumping of treated or untreated effluents, poor structured sewerage and drainage system, etc. In the present study, the water quality of five important rivers namely, Gola, Kosi, Ramganga, Saryu and Lohawati rivers were investigated which flow through the different districts of Kumaun region of Uttarakhand Himalaya. The water of all these rivers serves as the major source for drinking and irrigation purposes in these districts of the Kumaun region of Uttarakhand. River water samples collected in pre-monsoon and post-monsoon seasons of the years 2011 and 2012 were analyzed for various water quality characteristics. Statistical analyses indicate positive correlation among most of the chemical parameters. Piper diagram illustrates that all the water samples fall in Ca–Mg–HCO3 hydrochemical facies, Moreover, the suitability of water for drinking purposes determined by water quality index indicated that river water in both the seasons is unsuitable. Irrigation water quality of all the river water was found suitable during both the seasons according to the result of sodium adsorption ratio, sodium percentage and residual sodium carbonate. The present study revealed that major factors contributing to deterioration of water quality of all the rivers might be eutrophication, tourism, anthropogenic and geogenic processes. Therefore, to restore the vitality and water quality of all these rivers, proper water resource planning programme should be developed.

The assessment of groundwater vulnerability is essential especially in developing areas, where agriculture is the main source of the population. In the present study, four different overlay and index method, namely, DRASTIC, modified DRASTIC, pesticide DRASTIC and modified pesticide DRASTIC are implemented with a view to identifying the most appropriate method that predicts the vulnerable zone to groundwater pollution. Sensitivity analysis reveals that net recharge is the most influential parameter of the vulnerability index. Cross comparison of model output shows the highest similarity of 97% is observed between drastic and modified drastic while the maximum difference in models prediction of 49% is observed between modified drastic and pesticide drastic. Reported nitrate concentrations in groundwater are considered for validation of model-generated final output map. The prediction power of the models are assessed using success and prediction rate method and it highlights DRASTIC model as the most suitable model with 89.69% and 84.54% of the area under area under the curve (AUC) for success and prediction rate respectively.

Effective implementation of environmental regulations is an important concern for emerging economies that face serious environmental degradation. In this paper we analyze compliance and enforcement of environmental regulations in India. In particular, we model: (i) plant-level compliance with water and air pollution control laws in the state of Punjab, and (ii) the decisions of the regulatory agency, namely, the Punjab Pollution Control Board to enforce these laws through inspections and other administrative actions. The two decisions are interrelated. For a sample of 117 large water polluting plants and 109 large air polluting plants the probability of inspection influences plant-level compliance and vice versa. We also find enforcement activity is targeted towards frequent violators. Plants that belong to dirty industries are more stringently monitored but those belonging to more profitable firms less so. Plants with high abatement costs and those that are new comply less frequently.

COVID-19 induced lockdowns have had far reaching impacts on the rural sector, particularly on women farmers. These impacts have been exacerbated by lack of access to reliable and timely agriculture information. Using panel phone survey data from India and Nepal, we study how women's access to agricultural extension was impacted by the lockdowns and its effect on agricultural productivity. We find that women's already low access to formal extension was reduced further, leading to an increased reliance on informal social networks. In both countries, nearly 50% farmers reported negative impacts on productivity due to inaccessibility of information during the lockdown. In India, we find that access to formal extension is mediated by crop type, geographic location and caste identity. We discuss ways in which extension systems in India and Nepal can be made more inclusive and resilient to future crisis, including by adapting group and community-based approaches to post-pandemic best practices.

Northwestern India has been identified as a significant hotspot of groundwater depletion, with major implications for groundwater sustainability caused by excessive abstraction. We know relatively little about the detailed spatial and temporal changes in groundwater storage in this region, nor do we understand the interplay of factors controlling these changes. Groundwater managers and policymakers in India require such information to monitor groundwater development and make strategic decisions for the sustainable management of groundwater. Here, we characterise high-resolution spatio-temporal variability in groundwater levels and storage change across northwestern India through analysis of in situ measurements of historical groundwater level data. We note a slow gain in groundwater storage of + 0.58 ± 0.35 km3 for the pre-monsoon and + 0.40 ± 0.35 km3 for the post-monsoon period between 1974 and 2001. However, from 2002 to 2010, groundwater storage was rapidly depleted by -32.30 ± 0.34 km3 in the pre-monsoon and -24.42 ± 0.34 km3 in the post-monsoon period. Importantly, we observe marked spatial heterogeneity in groundwater levels and storage change and distinct hotspots of groundwater depletion with lateral length scales of tens of kilometers. Spatial variability in groundwater abstraction partially explains the depletion pattern, but we also find that the sedimentological heterogeneity of the aquifer system correlates broadly with long-term patterns of groundwater-level change. This correlation, along with the spatial agreement between groundwater level change and water quality, provides a framework for anticipating future depletion patterns and guiding groundwater monitoring and domain-specific management strategies.

Nepal’s labor migration history dates back to the colonial period in India when Nepali youths were recruited in the army of the East India Company in the early 19th century, and even prior to this period, Nepali men served in the army of Shikh ruler Ranjit Singh in Punjab (included territories of present-day India and Pakistan). This was followed by seasonal and longer-term labor migration to India. In the last 30 years, migration has reached exceptionally high levels, with the new generation of labor migrants heading to the Gulf States and Malaysia, as well as other destinations such as South Korea, Japan, Poland and Romania. The 1981 Nepali census classified over 400,000 household members as ‘absentees’ (those who were away or intend to be away from home for six or more months) and this increased to about 2.2 million by 2021. The destination of migrants over these years changed considerably. While in 1980, an overwhelming majority (93%) went to India, from the 1990s onwards, this shifted to the Arabian Gulf States and Malaysia, which accounted for over 90% of migrants by the 2010s, with fewer than 10% continuing to travel to India.
