The M&E system should be designed to be capable of capturing a variety of positive and negative trends across the community over different time scales. Monitoring strategies should also consider that a variety of positive community-level impacts will occur. For example, rapid changes in and alleviation of “income poverty” is likely to produce significant improvement in the nutrition status of children under five years of age. Nutritional changes can occur both acutely (over days and weeks) and chronically (over months and years) with significant direct effects on other disease states, such as anemia, malaria, pneumonia, and so on. Nutritional-effects data are relatively easy to capture by systematically measuring height, weight, and age in children under age five.
