Human Trafficking, Gender Violence, and Environmental Challenges in South Asia

When we talk about security, the image that usually comes to mind is soldiers, borders, and weapons. But over the last few decades, scholars and institutions have argued that the real test of security is whether ordinary people can live free from fear and free from want. This is the idea of human security, and South Asia is one of the clearest places to see why it matters. Behind the region’s growth stories lie three deeply connected crises: violence against women and girls, the trafficking of human beings, and an environment under severe stress. None of these can be solved by guarding a border. They demand a much broader understanding of what keeps people safe.

From state security to human security 🔗

The traditional view treats the state as the thing to be protected. The human security approach shifts the focus to the individual, asking whether people have enough food, health, dignity, and protection from harm. This reframing is especially useful for South Asia, home to roughly a quarter of humanity packed into a relatively small landmass with high population density, widespread poverty, and fragile institutions.

The three threats covered here are not separate silos. Gender violence pushes vulnerable women and girls into the hands of traffickers. Environmental shocks deepen poverty and uproot families, which in turn feeds both trafficking and gender-based abuse. Treating them as one interlocking problem is the heart of the human security lens.

Gender violence and the unequal start of life 🔗

For millions of girls in the region, insecurity begins before birth. Discrimination is woven into family decisions about who deserves to be born, fed, and educated. This is not violence in the dramatic sense, but a slow, structural harm that shapes entire lives.

The problem of the missing girls 🔗

A strong preference for sons, combined with the dowry system that treats daughters as an economic burden, has driven sex-selective abortion and, in some areas, female infanticide and the neglect of girl children. The United Nations Population Fund has documented how prenatal diagnostic technologies introduced from the 1970s onward were misused to alter the sex composition of children, distorting sex ratios across India and neighbouring countries. The economist Amartya Sen famously described the result as tens of millions of “missing women” across Asia. A skewed sex ratio is not just a demographic statistic. It is linked to rising trafficking of women for marriage and sex work, creating a vicious circle.

Malnutrition and the denial of education 🔗

Unequal nutrition: When food is scarce, girls often eat last and least. UNICEF reports that roughly one in five adolescent girls in South Asia is malnourished, and that son preference can even shape discrimination in breastfeeding. Interrupted schooling: Girls are also more likely to be pulled out of school for domestic work or early marriage. This matters beyond fairness. Educated women tend to have more agency over family decisions, which is why education is one of the most powerful long-term tools against gender-based discrimination.

Violence across the life cycle 🔗

Domestic violence, dowry-related harassment, sexual assault, and early marriage follow many women throughout their lives. During crises such as floods or displacement, the breakdown of normal protections leaves women and girls even more exposed to abuse. The World Bank has highlighted how gender-based violence and trafficking are tightly connected challenges across the region, requiring survivor-centred services rather than one-off interventions.

Human trafficking: modern slavery in the region 🔗

Human trafficking is often called modern slavery because victims are bought, sold, and forced into labour or sexual exploitation against their will. South Asia carries one of the heaviest burdens in the world, both as a source and as a destination.

Who is trafficked, and why 🔗

Women and girls make up the overwhelming majority of trafficking victims, pushed into forced prostitution, domestic servitude, and bonded labour in places like brick kilns and quarries. UN Women notes that women and girls are disproportionately affected, and that the Asia region accounts for a large share of those trafficked globally. Trafficking rarely stands alone. It intersects with the smuggling of drugs and arms and with wider organised crime networks.

Cross-border routes 🔗

Open and porous borders make the region especially vulnerable. The 2025 Trafficking in Persons Report on India describes how traffickers fraudulently recruit Nepali and Bangladeshi women and girls for sex trafficking inside India, sometimes disguising exploitation as marriage. Rohingya refugees, already displaced and without legal protection, are also exploited in both sex and labour trafficking. The same report points out that India has one of the world’s largest emigrant populations, and traffickers prey on migrant workers seeking jobs abroad.

The drivers: poverty, social norms, and weak enforcement 🔗

The Asian Development Bank’s regional study on Bangladesh, India, and Nepal traces trafficking back to a familiar set of root causes. Poverty and the lack of economic opportunity make false promises of good jobs irresistible. Social norms that devalue women lower the cost of treating them as commodities. Weak law enforcement and corruption allow traffickers to operate with little fear of punishment, and survivors often receive little support from justice systems. Because the trade crosses borders so easily, no single country can fix it alone, which is why regional cooperation is repeatedly stressed as essential.

Environmental insecurity and the scramble for resources 🔗

The third pillar of insecurity is environmental. South Asia is one of the most climate-vulnerable regions on the planet, and environmental stress steadily erodes the foundations of human well-being: clean water, food, and a stable place to live.

Climate change as a threat multiplier 🔗

Climate change rarely creates conflict on its own. Instead it acts as a multiplier, worsening existing pressures. Retreating Himalayan glaciers, erratic monsoons, and more frequent floods and droughts strike a region where a large share of people still depend on agriculture and live close to the poverty line. The Stimson Center has examined how the contested high mountains of the Himalaya-Karakoram-Hindukush, including the Siachen glacier disputed by India and Pakistan, sit at the intersection of melting freshwater sources and unresolved military tensions. When basic needs like drinking water and electricity become daily struggles, the line between an environmental problem and a security problem blurs.

Displacement, migration, and conflict 🔗

Environmental disasters do not just damage property. They move people. The Center for American Progress documented how floods in Assam in 2012 displaced around 1.5 million people, while Cyclone Aila in 2009 uprooted some 2.3 million. Large-scale movement of people strains the resources of host communities and can spark competition and tension over land, water, and jobs. World Bank projections cited widely in climate-security research suggest that, without strong action, climate change could displace well over a hundred million people within their own countries across regions including South Asia by 2050.

How environmental stress feeds the other crises 🔗

Here the three threats fold into one another. When a flood destroys a family’s livelihood, daughters may be married off early or sent away for work, walking straight into trafficking networks. Displaced people living without legal status are among the easiest targets for exploitation. A report on climate security in South Asia maps out how risks around water, ecosystems, loss and damage, and migration are deeply interconnected, and argues that disaster risk management can actually become a vehicle for building trust and cooperation between rival states.

Towards comprehensive human security 🔗

If insecurity is interconnected, then so must be the response. A few priorities consistently emerge from the research. Sustainable development: Tackling chronic poverty removes much of the desperation that traffickers and exploiters rely on. Investing in women and girls: Education, nutrition, and legal protection address gender violence at its roots and reduce vulnerability to trafficking. Regional cooperation: Because trafficking routes, rivers, and climate impacts ignore national boundaries, shared frameworks and information-sharing are far more effective than isolated national policies. Stronger institutions: Genuine enforcement of existing laws, supported by survivor-centred services, closes the gap between good legislation and real protection.

The deeper lesson is that security cannot be measured only by the strength of armies or the integrity of borders. It must also be measured by whether a girl is allowed to be born and educated, whether a worker can migrate without being enslaved, and whether a family can survive the next flood. Until these everyday freedoms are secured, the region’s progress will remain incomplete.

What do you think? Should governments treat climate change and trafficking as national security threats on par with military ones, and what would change if they did? And in your view, is regional cooperation across South Asian states realistic given existing political tensions, or are national solutions the more practical path?
