In many hillside neighborhoods on the edges of Lima, the hardest part of seeing a doctor is the walk down. When the only route to the main road is a loose dirt slope, every trip to a clinic, school or market carries a risk of falling. That is why we think about infrastructure and health as one conversation.
In this article, you will learn:
Public health experts talk about the social determinants of health: the conditions where people live, work and move that shape wellbeing long before anyone reaches a doctor. Physical infrastructure is one of the most visible. In hillside communities, it affects health in three main ways.
A health post can be open and staffed and still be out of reach. The UN Secretary-General’s High-Level Advisory Group on Sustainable Transport describes mobility as a means to reach jobs, education and the services that support healthy lives. Sustainable mobility frameworks also stress equity: access should not depend on income or location.
On a steep hillside with no safe path, these groups face the hardest climb:
When the journey feels dangerous, people may postpone care until a manageable problem becomes serious.
Many homes in Lima’s human settlements were built by families on rocky, unstable hillsides, often with reed mats or plywood. Without stairs or railings, everyday tasks become fall risks:
Seasonal events make this worse. You can read more about how El Niño affects Lima’s settlements and why slope stability matters there.
Infrastructure also has a legal side. In communities like 2 de Diciembre, the chain works like this:
Staircase → supports land title efforts → land titles are often required for public water and electricity → better sanitation and safer homes
Health is also mental. Living with constant physical risk adds stress, a theme we explore in our article on the psychological impact of safe housing.
The 2 de Diciembre staircase is a clear example of infrastructure and health working together.
| Partner | Role |
|---|---|
| Community residents | Worked on site and know where people actually walk and which homes need connecting |
| Local architects and engineers | Led the technical work and know the terrain |
| Student volunteers | Joined from universities across the United States to mix cement, lay bricks and install handrails |
| Before | After |
|---|---|
| Trips to school, work or the clinic meant crossing dangerous slopes, especially in rainy weather | Children have a safer route to school |
| Reaching health services was difficult and risky | Families can reach health services more easily |
| Elderly residents risked injury just to leave home | Elderly residents and people with limited mobility can move safely |
No new clinic was built, yet reaching care became safer for the whole neighborhood. That is why we treat a staircase as a healthcare intervention: it removes a physical barrier between people and services that already exist.
For students in civil engineering, architecture or urban development, a staircase project turns classroom concepts into real decisions:
The program also runs in Cusco, Peru, and Tena, Ecuador, where projects can include greenhouses, home construction and other community infrastructure. Read how students gain real-world experience with Safe Homes, or explore our development service learning trip options.
On a hillside, the link between infrastructure and health is easy to see: fewer risky trips and easier access to care.
If you are a student interested in engineering, architecture or community development, or an educator looking for a program with real technical depth, fill out the form to get more information about the Development Service Learning Trip.
You will work alongside local professionals and communities in Lima, Cusco or Tena.
