The construction and operation of large hydroelectric dams can severely disrupt local food security by diminishing access to and consumption of vital food sources like fish. This resource management research insight is drawn from a 2023 study published in Environmental Conservation. Using Longitudinal observational study, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing large-scale projects that alter natural environments, prioritize understanding and mitigating impacts on local food systems and resource availability to ensure community well-being.

Key Findings
- 01Fish became less common in the diet over time.
- 02The quantity of fish consumed per person decreased.
- 03Adding more fish species to the diet did not increase overall consumption per person.
- 04The most significant changes in fish consumption occurred between 2013 and 2016, during the post-construction and pre-full operation phase, and were exacerbated during drought periods.
- 05Environmental impacts of the dam, rather than solely climatic events, were identified as the primary driver of reduced fish consumption.
Application
Design takeaway
When designing large-scale projects that alter natural environments, prioritize understanding and mitigating impacts on local food systems and resource availability to ensure community well-being.
How to apply
Before initiating projects that modify river systems or natural habitats, conduct thorough research into the dietary dependencies and resource access of local populations. Develop adaptive management plans that address potential disruptions to food security.
Project actions
- 01When researching a project, consider how your design might affect the availability of natural resources for local communities.
- 02Think about the long-term consequences of your design choices on ecosystems and the people who depend on them.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Longitudinal data collection over a significant period (2012-2021).
- +Inclusion of construction, operation, and drought periods provides a comprehensive view of impacts.
Limitations
It can be challenging to isolate the exact impact of a single project on resource availability and consumption, as many other environmental and social factors are usually at play.
Reliability & validity
The study's reliability is supported by longitudinal data collection. Validity is enhanced by considering multiple factors (dam operation, drought) and their interactions, though isolating exact causal links can be challenging.
Think critically
To what extent can the impacts of large infrastructure projects on food security be fully mitigated, and what are the ethical responsibilities of designers in such scenarios?
Design Principles
"Resource alteration projects must proactively assess and mitigate impacts on local food security and ecosystem services."
This research highlights the critical need for designers and engineers to consider the cascading socio-ecological impacts of large infrastructure projects. Understanding how resource extraction and alteration affect local communities' food systems is essential for developing more sustainable and equitable designs.
What This Means for Your Design
Building big dams can make it harder for people living nearby to get and eat enough fish, which is a main food source for them.
How to use in your project
- 1.Use this research to justify the importance of considering social and environmental impacts in your design process, especially when dealing with resource management.
- 2.Reference this study when discussing the potential negative consequences of altering natural environments and the need for sustainable solutions.

Paragraph starter
The Belo Monte Dam case study illustrates how large-scale infrastructure projects can significantly impair local food security by disrupting natural resource availability. Lopes et al. (2023) found a marked decrease in fish consumption among Amazonian riverine communities due to the dam's environmental impacts, underscoring the critical need for designers to integrate comprehensive social and ecological impact assessments into their project planning.
