Which of the following is NOT an indicator of environmental risk in humanitarian settings?

• A. WASH-related disease incidence
• B. Vector indices
• C. Crop yield
• D. Waste accumulation

Answer: (C)

Environmental health risk indicators in humanitarian settings track exposure and transmission pathways of hazards in the environment. WASH-related disease incidence directly signals illnesses linked to water, sanitation, and hygiene conditions, showing how contaminated water or poor hygiene translates into disease risk. Vector indices reflect the presence and density of disease-carrying pests, indicating potential transmission risk. Waste accumulation points to unsanitary conditions that can spread disease and attract vectors. In contrast, crop yield is a measure of agricultural production and food security rather than a direct signal of environmental health risk or disease exposure in the immediate environment. It’s influenced by many factors beyond environmental hazards, such as farming practices and market conditions, so it’s not a direct environmental risk indicator. Therefore, crop yield is the not an indicator of environmental risk in humanitarian settings.
