During a study conducted in January 2010 by researchers of the Columbia University Mechanical Engineering Department in New York City, approximately 300 farmers were surveyed in rural Mali. Farmers were randomly sampled via standard proportional, stratified, cluster techniques. Data collection took place through the use of HTC G1 smartphones running Google’s Android operating system. The phones were equipped with Open Data Kit (ODK) software; a system that immediately digitizes data for analysis, allows for remote monitoring of the collection progress, and facilitates the gathering of data, eliminating the need for paper surveys and therefore significantly reducing survey times. ODK has the potential for a profound impact on the future of data gathering, particularly in development applications where locations may be remote and budgets tight, yet where mobile phone use is rapidly increasing with the expansion of service
coverage.
