“…Subsidence can be natural or Anthropogenic. Natural land subsidence comprises tectonics, coastal subsidence caused by extreme geometeorological events, Climate changes, regional sea level rise (RSLR), global warming, natural sediment compaction, glacial isostatic modification, and changes in sun earth geometry are sluggish and slow, [35,36,37,38,39].…”

Land subsidence events, natural or anthropogenic, will be future national challenges for India. The positioning of the Indian plate in the globe, and human activities on the frustum compel land subsidence everywhere, on mountains, in deltas, riverbeds and in settlements. Many mega deltas of the globe including India are sinking, shrinking, and subsiding which shall invite catastrophes. The present search uses the available datasets in print media, books, information technology and electronic media. The survey responses sourced from websites were physically ground verified, etc. Considering Bhuban data, Arc GIS software and Microsoft Excel, India's hazard, organic and inorganic maps are prepared to alert our forthcoming ancestors. Using those maps the zonal map of geo-hazards in various states of India can be prepared and future action plans can be shorted out. Studies reveal that geo-hazards in various zones of India are different. Hazards on mountains are land slide, torrential rain, and land subsidence, whereas the calamities along the coasts, and deltas are cyclones, coastal erosions, floods, and deltaic subsidence. With surging human activities, the frequency and intensity of geo-hazards are swelling presently. It is high time to plan to appease the vulnerability of the rising devastation to attain sustainability of SDG Targets 11.5, and 13 which will moderate the adverse effects of such disasters.

“…Nitrate is relatively nontoxic to fish and causes no health hazard except at exceedingly high levels (above 90 mg/l) (Stone and Thomforde, 2004;Santhosh and Singh, 2007). Nitrates have immense significance as major nutrients for the succession and productivity of phytoplankton and aquatic macrophytes (Mishra and Patro, 2015).…”

Anthropogenic activities causing deterioration in water quality and a decrease in meeting the ecosystem service potentials of surface water are considered one of the major basic environmental challenges. Water samples were collected from three sampling stations (Ogurugu, Otuocha, and Otu- Nsugbe) in the Anambra River Basin and analyzed following standard protocols and procedures for nine months. The cosystem services potentials of the Anambra River Basin were evaluated using physico-chemical parameters and some indices: Comprehensive pollution index (CPI), nutrient pollution index (NPI), salinity potential, and soluble sodium percentage (SSP). All the water quality parameters were within the standard level for drinking water, aquaculture practice, recreation (swimming/bathing) and agricultural purposes, with the exception of pH and phosphate, whereas dissolved oxygen met aquaculture criteria only in station II. Comprehensive pollution index (0.150 – 0.449), nutrient pollution index (0.07 – 0.46), and soluble sodium percentage (6.0% -26.92%) were within the category of non-polluted or excellent to sub-clean. Potential salinity (39.39 - 97.19) was high, indicating water from the Anambra River Basin contained crystallized solutes. Conclusion: the Anambra River Basin is not at risk of eutrophication but may not support irrigation program due to the high potential salinity. However, the river needs to be monitored, and anthropogenic activities need to be regulated.
