THE FOLLOWING IS A PROPOSAL FOR WORK NECESSARY TO COMPLETE THE NASA NEW INVESTIGATOR PROGRAM GRANT (NNX15AC64G) FOLLOWING THE MOVE OF THE PRINCIPAL INVESTIGATOR FROM PRINCETON UNIVERSITY TO CLARK UNIVERSITY S GRADUATE SCHOOL OF GEOGRAPHY. THE ORIGINAL OBJECTIVES OF THE PROPOSAL WERE TO: 1. IDENTIFY PATTERNS OF CROPLAND CHANGE WITHIN ZAMBIA 2. IDENTIFY LANDSCAPE-SCALE TRENDS IN AGRICULTURAL PRODUCTIVITY WITHIN ZAMBIA S CROPLAND. 3. UNDERSTAND THE RELATIONSHIPS BETWEEN CHANGES IN CROP PRODUCTIVITY LANDCOVER AND CLIMATIC VARIABILITY. TO ACHIEVE THESE OBJECTIVES THE PROJECT WAS DESIGNED AROUND THREE PRIMARY TASKS: 1. DEVELOP A NEXT-GENERATION LANDCOVER MAPPING SYSTEM THAT CAN ACCURATELY DELINEATE SMALLHOLDERS FIELDS AND USE THIS SYSTEM TO TRACK CROPLAND CHANGES OVER TIME. 2. DEVELOP A METHOD TO ACCURATELY ESTIMATE SMALLHOLDERS CROP YIELDS BY INTEGRATING IN SITU ENVIRONMENTAL SENSING REMOTE SENSING AND NUMERICAL MODELING AND APPLY IT TO ESTIMATE HOW ANNUAL YIELDS HAVE CHANGED OVER TIME. 3. USING THE RESULTS OF TASKS 1 AND 2 UNDERTAKE STATISTICAL ANALYSES TO DETERMINE WHETHER A) PRONOUNCED CROP PRODUCTIVITY INCREASES ARE CORRELATED WITH AND PRECEDE INCREASES OR DECREASES IN FARMLAND AND B) WHETHER HIGHER YIELDS LEAD TO INCREASED OR DECREASED SENSITIVITY TO CLIMATIC VARIABILITY PARTICULARLY RAINFALL. THIS PROPOSAL NECESSITATED BY THE PI S CHANGE OF INSTITUTION (TO CLARK UNIVERSITY EFFECTIVE AUGUST 21 2017) ADDRESSES THE REMAINING WORK TO BE DONE TO COMPLETE THESE TASKS FACTORING IN THE PROGRESS MADE AGAINST THE ORIGINAL TASKS AND THE EVOLUTION OF THE PROJECT SINCE INCEPTION.
