Salinity is an agricultural problem that significantly affects rice production and is spreading in fields across the world. Poor irrigation practices, insufficient irrigation water during cropping seasons with low rainfall, high evaporation, increasing saline groundwater levels, and saltwater intrusion in coastal areas are among the significant causes of salinity.

Salinity cuts rice production by 30–50%. Because this growing environmental crisis plagues the world's largest rice-producing and exporting countries, such as Vietnam, Thailand, Bangladesh, and India, it threatens the future of agri-food systems that feed billions of people.
 
But millions of smallholder rice farmers living along the coastal areas of Asia and Africa are already feeling the brunt of this ever-spreading scourge.

A vast and lasting damage

Salinity inflicts long-lasting damage that affects generations of farmers. In October 1999, a tropical depression in the Andaman Sea gradually developed into a superstorm, the Paradip Cyclone, barrelling towards India. It became the most severe weather system to strike Odisha in the 20th century.
