The logo of Measured Change is the Greek letter delta represented as a Penrose triangle.

Delta is the mathematical and scientific diacritic for change.

The Penrose triangle is an impossible object; what we think we see is not always what is happening.

The droplets, ear of wheat and tipi represent water and sanitation, nutrition and food security, and shelter - the most basic human needs for survival.

The rod of Aesclepius reflected in the triangle is a symbol of health or medicine. A symbol including two snakes around a staff, or a winged staff, is Caduceus, a symbol of commerce, though it is often mistakenly used to symbolise medicine especially in the military.
