Farmers' loss due to Guinea worm disease: a pilot study

Area of Science:

• Public Health
• Agricultural Economics
• Tropical Medicine

Background:

• Guinea worm disease (GWD) causes significant disability and economic losses, particularly affecting farmers in endemic regions.
• Previous economic impact assessments often simplify disability by equating lost workdays to monetary values, potentially missing crucial contextual factors.
• Understanding the specific mechanisms of GWD-related loss within agricultural systems is essential for accurate impact evaluation.

Purpose of the Study:

• To qualitatively explore how Guinea worm disease affects farmers' productivity and economic well-being.
• To identify key factors, such as seasonality and crop type, that mediate the economic impact of GWD on farming households.
• To inform the design of future large-scale surveys and research on GWD's socioeconomic consequences.

Main Methods:

• A qualitative case study approach was employed.
• Twenty in-depth interviews were conducted with farmers affected by Guinea worm disease.
• Data analysis focused on understanding the relationship between the timing and duration of illness and agricultural activities.

Main Results:

• Farmers' economic losses due to Guinea worm disease are strongly influenced by the time of year they experience disability.
• The impact of GWD on productivity can vary depending on the flexibility of planting and harvesting schedules for different crops (e.g., cassava).
• The duration of the disability is a critical factor determining the extent of economic loss experienced by affected farmers.

Conclusions:

• The economic burden of Guinea worm disease on farmers is complex and context-dependent, influenced by agricultural calendars and crop types.
• Qualitative insights are crucial for developing more accurate and sensitive tools to measure the socioeconomic impact of GWD.
• Further longitudinal research is needed to fully understand the long-term effects of GWD on farming communities.
