Smallholder livelihoods in the Peruvian Altiplano (central Andes) are frequently threatened by weather extremes, including droughts, frosts and heavy rainfall. A project was undertaken to investigate characteristics of smallholder households that explain the link between climate vulnerability and food security. This study revealed distinct groups of smallholders with regard to their ability to meet food requirements. Taking up the basic concept of pattern analysis, vulnerability was assessed based on similarities at the household level. The pattern approach was extended in testing the validity of the identified patterns using outcomes of a specific exposure and reported mechanisms from independent information sources. Such a validated and manageable categorization of the heterogeneous characteristics of smallholder households provides a solid basis for advancing regional development initiatives.
