Climate change and its impact on natural resources
(Elsevier, 2021) Jyoti Kushawaha; Sivaiah Borra; Abhishek Kumar Kushawaha; Gurudatta Singh; Pardeep Singh
The places, population, and flora and fauna are at stake because of climate change. Natural resources regulate the economic, social, and cultural lives. Water is a basic need in everyday life, and its cycle is inextricably linked with climate change. The main concern is the changing scenario of the water resources and the factors supporting the condition of water scarcity. Forest resources have a very high value as a maximum of the national population, and the whole tribal community is dependent on the forest resources. Moreover, water itself plays a vital role directly or indirectly to affect the climate change on the oceans including warming, sea-level rise, changes in ocean currents pattern, coastal flooding, ocean acidity, and sea ice. These effects can, in turn, lead to significant changes in regional climate, climate pattern, and human migration. This chapter discusses climate change, its indicators and its impact on natural resources, especially on water, ocean, and forest resources. Moreover, the impact of climate change on water resources is the fundamental concern in this chapter. The industrialization leads to the emergence of employment, economic growth, development, and high living standards, but along with this the climate change poses a fundamental threat to ecology and environment because of the exploitation of the natural resources recklessly. © 2021 Elsevier Inc.

Geochemical assessment of groundwater quality in Keonjhar City, Odisha, India
(Springer Science and Business Media Deutschland GmbH, 2020) Sughosh Madhav; Ashutosh Kumar; Jyoti Kushawaha; Arif Ahamad; Pardeep Singh; S.B. Dwivedi
This study intended at the recognition of hydrogeochemical processes and groundwater excellence by applying different quality indices for intake and farming functions. Thirty groundwater samples were taken from the Keonjhar city, Odisha, and different hydrogeochemical parameters were analyzed to understand groundwater excellence. In the current work, cation chemistry shows the sequence of Na+ > Ca2+ > Mg2+ > K+ and anions chemistry HCO3−>Cl−>SO42−>NO3. Gibbs plot indicates that groundwater samples are found in rock dominance. Different ratios of the major ions indicate that silicate weathering and anthropogenic activities were the major sources of ions in the groundwater. Factor examination also validates that both natural and anthropogenic actions are contributing ion in the aquifer. Based on diverse indices used for agriculture purpose, the greater part of the groundwater in the investigative region is appropriate for farming function. Groundwater quality is a dynamic process and subject to seasonal and spatial changes, so continuous assessment and monitoring is required. This study provides the severity of NO3 contamination in the study area as 40% of samples show the values more than the permissible limit. So, proper remediation measures are required prior to consumption of groundwater. © 2020, Springer Nature Switzerland AG.
Spatial Identification of Vulnerable Coastal Ecosystems for Emerging Pollutants
(Springer Science and Business Media B.V., 2022) Anuradha Kumari; Rahul Harshawardhan; Jyoti Kushawaha; Ipsita Nandi
Coastal ecosystems play a crucial role in maintaining ecosystem services. These also harbor diverse groups of flora and fauna. Increased anthropogenic activities are degrading coastal ecosystem at a very fast pace. This in turn is adversely affecting species biodiversity as well as impacting human health and well-being. Among various pollutants affecting coastal ecosystem, certain contaminants known as emerging pollutant are causing great loss to its services and biodiversity. These contaminants are given undue concern in the past but are adversely affecting humans and marine biodiversity. These contaminants require different strategies for their detection, impact, as well as management. Hence it is required to have a complete insight into source, chemistry, and potential impact of these pollutants. In this chapter, a vulnerability map is created for the states along Indian coastline based on their potential sources and population of states. It was also observed that a wide knowledge gap exists among different coastal states regarding the occurrence of emerging pollutant. This study might act as an eye-opener for scientific community toward existing knowledge gap and further direct toward their investigation and management. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
