Summary
Artisanal fishers on Lake Victoria face significant drowning risks. Visual journey risk maps, co-created with fishers, highlight safety needs and intervention opportunities for improved fishing safety.
Area of Science:
- Occupational Safety and Health
- Human-Centered Design
- Aquatic Risk Management
Background:
- Artisanal fishing on Lake Victoria is a vital livelihood but poses substantial drowning risks.
- Understanding daily activities and associated hazards is crucial for effective safety interventions.
Purpose of the Study:
- To document and understand the daily activities and risks faced by artisanal fishers on Lake Victoria.
- To identify opportunities for intervention design to mitigate drowning risks.
Main Methods:
- Employed human-centered design techniques combined with drowning risk analysis.
- Developed visual journey risk maps for two distinct fishing methods: long-line and seine net fishing.
- Engaged fishers in a participatory mapping process to capture their insights on risks and mitigation.
Main Results:
- Two visual journey risk maps were created, detailing "before," "during," and "after" stages for both fishing types.
- Identified specific risks including storms, boat capsizing, collisions, fatigue, and equipment failure.
- Highlighted the need for holistic safety interventions such as weather forecasts, buoyancy devices, and formal training.
Conclusions:
- Co-creating visual journey risk maps with fishers and experts provides deep insights into livelihood risks.
- The process visually presents opportunities for risk mitigation and intervention design.
- Further research should combine design tools with scientific analysis to pinpoint effective control measure implementation points.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
39
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Design Example: Measuring Distance Between Two Points with Obstructions
26
When measuring distances in areas with physical obstructions, such as a lake in a field, surveyors must employ techniques to calculate accurate lengths without direct line measurements. One effective method is the offset technique, which allows for precise distance estimation over inaccessible stretches.In this scenario, a surveyor must measure a side of an area that crosses a lake. Since the measuring tape cannot span the lake, the surveyor begins by establishing a baseline that aligns with...
