According to World Bank reports, approximately 225 Sundarbans residents die annually from diarrhea alone, with around 1.5 million cases of waterborne illnesses reported each year. The contaminated water supply has become a breeding ground for cholera, dysentery, hepatitis A, typhoid and other communicable diseases that spread rapidly through communities lacking adequate sanitation infrastructure. The situation is particularly dire during the monsoon season when flooding further contaminates already compromised water sources, creating ideal conditions for disease transmission.

The lack of access to safe drinking water has forced many communities to consume brackish water with elevated salt content, leading to immediate health complications including severe dehydration, electrolyte imbalances and gastrointestinal disorders. Children are particularly vulnerable to these conditions, as their smaller body mass and developing immune systems make them more susceptible to the harmful effects of contaminated water consumption.

Salinity-Induced Health Complications

The progressive salinization of the Sundarbans environment has created a unique set of health challenges that extend far beyond water contamination. Climate change has driven progressive river salinization in the low-lying coastal areas, fundamentally altering the chemical composition of the environment in which communities live and work. Villagers in blocks of North and South 24 Parganas have been reporting increasing incidents of skin ailments, discoloration and endocrinological disorders directly linked to prolonged exposure to high-salinity environments.

The consumption of saline water has led to a range of cardiovascular complications, including hypertension and heart disease, as the human body struggles to process the excessive sodium intake. Long-term exposure to high salinity levels has been associated with kidney dysfunction, as the organs work overtime to filter out excess salt, leading to chronic kidney disease in many community members. The dermatological impacts are equally severe, with residents experiencing persistent skin infections, rashes and other dermatological conditions that resist conventional treatment methods.

Workers in the region, primarily women engaged in fishing and aquaculture activities, suffer from occupational health issues including PIDs, problems with eyesight and various skin diseases. The high salinity environment has created conditions where minor cuts and abrasions become infected more easily, leading to chronic wounds that are difficult to heal in the harsh environmental conditions.

Nutritional Deficiencies and Food Security Challenges

Climate change has severely compromised food security in the Sundarbans, leading to widespread malnutrition and dietary deficiency diseases. The increasing salinity in soil and water has made traditional agriculture nearly impossible, forcing communities to abandon crops that have sustained them for generations. The degradation of agricultural land has resulted in reduced crop yields and limited dietary diversity, creating conditions conducive to malnutrition, particularly among children and pregnant women.

The disruption of traditional fishing patterns due to changing water conditions and ecosystem degradation has reduced protein availability in local diets. Fish populations have declined or migrated to different areas, leaving communities without their primary source of protein and essential nutrients. This protein deficiency has contributed to stunted growth in children, anemia in women, and overall weakened immune systems across the population.

The lack of fresh fruits and vegetables due to soil salinization has led to widespread micronutrient deficiencies, including vitamin A, vitamin C, iron and zinc deficiencies. These nutritional gaps have resulted in increased susceptibility to infectious diseases, delayed wound healing, and impaired cognitive development in children. The situation is compounded by limited access to diverse food sources due to geographic isolation and economic constraints.

Mental Health and Psychological Impacts

The psychological toll of climate change on Sundarbans communities has been profound and far-reaching, with mental health disorders significantly increasing following extreme weather events. After Cyclone Aila in 2009, mental health issues including post-traumatic stress disorder, anxiety and depression became prevalent throughout the region. The constant threat of natural disasters, combined with the gradual loss of traditional livelihoods and environmental degradation, has created a persistent state of psychological stress among residents.

The uncertainty surrounding future climate impacts has led to chronic anxiety and depression, particularly among adults who bear the responsibility of providing for their families in increasingly challenging conditions. The loss of traditional knowledge and cultural practices due to environmental changes has created a sense of displacement and cultural grief that affects entire communities. Women, who often bear the brunt of resource scarcity and family care responsibilities, experience particularly high levels of stress and anxiety.

Children in the region show signs of developmental trauma related to repeated exposure to extreme weather events and environmental instability. The disruption of educational systems due to frequent flooding and infrastructure damage has created additional psychological stress for young people, affecting their long-term development and mental health outcomes.

Gender-Specific Health Impacts on Women

Women in the Sundarbans face disproportionate health impacts from climate change due to their traditional roles in water collection, food preparation, and family care. The increased difficulty in accessing clean water has placed additional physical and time burdens on women, who must travel longer distances to find safe water sources. This increased workload has led to physical exhaustion, musculoskeletal problems, and reduced time for self-care and income-generating activities.

Reproductive health issues have become increasingly common among women in the region, with high salinity exposure linked to complications during pregnancy and childbirth. The lack of access to clean water and adequate sanitation facilities has increased the risk of maternal infections and complications during delivery. Many women report irregular menstrual cycles and fertility problems that they attribute to environmental stressors and poor nutritional status.

The psychological stress of managing household needs in the face of resource scarcity has contributed to high rates of depression and anxiety among women. The increased domestic violence rates, partly attributed to economic stress and resource conflicts, have created additional health risks for women in the region. Limited access to healthcare services due to geographic isolation and damaged infrastructure has left many women without adequate medical support during critical health events.

Pediatric Health Crises and Child Development

Children in the Sundarbans face a multitude of health challenges that threaten their immediate well-being and long-term development. The high incidence of waterborne diseases among children has created a cycle of illness that impairs physical growth and cognitive development. Chronic diarrhea and frequent infections have led to malnutrition and stunted growth in many children, with long-term consequences for their physical and intellectual development.

The consumption of saline water by children has resulted in early onset of cardiovascular problems and kidney dysfunction, conditions typically associated with adult populations. The developing nervous systems of children are particularly vulnerable to the effects of dehydration and electrolyte imbalances caused by contaminated water consumption. Skin conditions and respiratory problems are common among children due to exposure to polluted air and water.

Educational disruption due to frequent flooding and infrastructure damage has affected the cognitive development and future prospects of children in the region. Many children are forced to participate in labor activities to support family income, further compromising their health and development. The lack of adequate nutrition during critical growth periods has resulted in irreversible developmental delays that will affect these children throughout their lives.

Community-Wide Health System Challenges

The health system in the Sundarbans faces enormous challenges in addressing the complex health needs of the population. Healthcare infrastructure is frequently damaged by storms and flooding, leaving communities without access to essential medical services during critical times. The isolation of many communities makes it difficult to deliver emergency medical care and regular health services.

During extreme weather events, water, sanitation and hygiene facilities in emergency shelters are often inadequate, making life particularly difficult for vulnerable populations including the elderly, pregnant women and persons with disabilities who require constant care and assistance. The lack of skilled healthcare providers willing to work in remote and challenging conditions has created gaps in medical care that affect all community members.

The traditional knowledge systems that communities have relied upon for healthcare are being disrupted by environmental changes, leaving people without familiar treatment options. The increased prevalence of new diseases and health conditions requires medical interventions that are often unavailable or inaccessible to remote communities. The economic burden of healthcare costs has become insurmountable for many families already struggling with climate-related income losses.

Occupational Health and Economic Impacts

The changing environment has created new occupational health hazards for workers in the Sundarbans. Fishermen and aquaculture workers face increased risks of injury and disease due to rough seas and unpredictable weather conditions. The high salinity environment has created conditions where occupational injuries are more likely to become infected and heal more slowly. Agricultural workers who have attempted to continue farming in saline conditions face unique health challenges including respiratory problems from salt-laden air and skin conditions from contact with contaminated soil.

The lack of alternative employment options has created situations where people must choose between immediate economic survival and long-term health consequences. This economic pressure has particularly affected women and young people who may engage in risky occupations out of necessity.
