Opening
Salinity ingress is a situation where the salinity of a region is affected by entry of salinity through other region or medium.
Causes of salinity ingress:
Body
(i) Sea level rise : leading to coastal erosion of the soil.
(ii) Marine Pollution : that involves dumping of wastes causing change in salinity ingress
(iii) Change in tidal flow or weakening of the Oceanic currents. (iv) change in upwelling or downwelling. or gulf current = saline.
(iv) Thawing of glaciers affect entry of salinity in region.
Consequences:
(i) Reduced fertility of soil - overall yield reduces.
(ii) Land degradation when done long term.
(iii) Need for excessive irrigation to convert the fallow land.
(iv) Reduction in earnings of farmers.
(v) Affect negatively on blue economy due to Eutrophication.
(vi) Hazards for habitation on coastal areas
(eg): India's 7500 km coastline has dense population.
Solutions :
→ Green Economy to reduce the emissions of GHGs.
→ Salinity treatment methods- like use of lime, gypsum.
→ Insitu conservation through bio-remediation.
Close
Salinity ingress has become a new disaster which must be studied deeply to reduce its ill effects.
