Physical Measurement

How will you collect and/or retrieve data?

Evaluators can track physical change over time using agreed measurement units and procedures in their sector. Each sector has particular indicators that track important change – for example health and nutrition levels, soil quality and rain levels, level of atmospheric pollution etc.
Specific examples of direct measurement options (Guijt and Woodhill, 2002295) include:
  • “Health/Nutrition: measuring the upper-arm circumference of children under five, degree of stunting in boys and girls under five, attendance at local clinics, etc.
  • Agriculture: annual yield/production, amount of fencing/terracing constructed, seed or fertiliser expenditures, livestock numbers, number of bore wells constructed, etc.
  • Natural resource management: kilometres of contour bunds, presence of rare species per unit area, survival rate of seedlings planted, etc.”
The physical measurements cluster includes two particular types of options.
