How Extreme Weather Is Increasing Unplanned Pregnancies in Sub-Saharan Africa

Droughts in Sub-Saharan Africa are increasing unintended pregnancies by limiting access to contraception, worsening economic stress, and reducing women’s decision-making power. The result is poorer health outcomes for children and weaker economic stability for women, highlighting a hidden human cost of climate change.

In the drought-prone regions of Sub-Saharan Africa, climate change is doing more than drying up crops and shrinking incomes. A new study by the World Bank's Africa Gender Innovation Lab, along with researchers from the Policy Studies Institute, Mekele University, and other institutions, shows that extreme weather is quietly reshaping family life. The research finds that droughts are increasing the number of unintended pregnancies, revealing a deeply human side of the climate crisis that often goes unnoticed.

The study uses data from 18 African countries collected over more than two decades. By combining health surveys with detailed rainfall data, researchers were able to track how changing weather patterns affect fertility decisions. Their conclusion is clear: when drought hits, more women end up having pregnancies they did not plan.

When Drought Hits, Choices Shrink

Drought affects households first and foremost through money. Many families in Sub-Saharan Africa depend on farming, so when rains fail, incomes drop quickly. Food becomes scarce, and priorities shift toward survival. In such situations, spending on healthcare and contraception often falls.

Access to clinics may also become harder, especially in rural areas. With fewer resources and less access to services, family planning becomes more difficult. As a result, unintended pregnancies become more common. The study shows that drought increases the likelihood of such pregnancies by about one to two percentage points. While that may sound small, across millions of people, it represents a major change.

Pressure on Women and Girls

The effects of drought go beyond economics. Social pressures also increase during tough times. Families facing financial stress may arrange early marriages for their daughters to reduce costs or secure financial support. These young brides often have little say in reproductive decisions, leading to early and unplanned pregnancies.

At the same time, women's decision-making power within households can weaken. Stress and uncertainty can also affect behavior, making it harder to consistently use contraception. In some cases, women may turn to risky coping strategies just to survive, which further increases the chances of unintended pregnancy.

Even education, which usually helps women make informed choices, does not fully protect against these pressures. The study finds that drought affects both educated and uneducated women in similar ways, showing how strong these structural challenges are.

The Cost for Children and Mothers

Unintended pregnancies have serious consequences for both mothers and children. Children born from such pregnancies are less likely to receive proper care before and after birth. They are less likely to be delivered in health facilities and more likely to suffer from illnesses like fever, cough, and diarrhea.

These early health problems can affect a child's growth, learning, and future opportunities. Over time, this can trap families in cycles of poverty.

For women, the impact is also significant. An unplanned child can make it harder to maintain stable employment. The study shows that women with unintended pregnancies are more likely to move from steady jobs to occasional or informal work. This reduces their income and independence, making it even harder to recover from economic shocks.

Rethinking Climate Solutions

The findings highlight an important message: climate change is not just about the environment. It also affects health, gender equality, and family well-being. As droughts become more frequent, these hidden impacts are likely to grow.

This means climate policies need to go beyond agriculture and infrastructure. Governments and organizations must ensure that reproductive health services remain available even during crises. Access to contraception, stronger healthcare systems, and better education for women can help reduce the risks.

The study makes it clear that protecting people from climate change is not only about saving crops or managing water. It is also about protecting choices, especially for women. In the face of a changing climate, the ability to decide when to have a child becomes even more important.

As the climate crisis deepens, its effects are reaching into everyday life in ways that are easy to overlook. This research brings attention to one of those hidden impacts, showing that behind every drought statistic is a story about families, futures, and the choices people are forced to make.
