BECAUSE SUCH MAPS SYNTHESIZE A RICH ARRAY OF INFORMATION RELATED TO BOTH THE ECOLOGICAL CONDITION OF LAND AREAS AND THEIR EXPLOITATION BY HUMANS  THEY ARE WIDELY USED FOR MODEL-BASED INVESTIGATIONS THAT REQUIRE INFORMATION RELATED TO LAND SURFACE BIOPHYSICAL PROPERTIES (E.G.  TERRESTRIAL CARBON MODELS  WATER BALANCE MODELS  WEATHER AND CLIMATE MODELS  ETC.)  AND ARE CORE INPUTS TO MODELS USED BY NATURAL RESOURCE SCIENTISTS AND LAND MANAGERS. AS THE EARTH S GLOBAL POPULATION HAS GROWN OVER THE LAST SEVERAL DECADES  RATES OF LAND COVER CHANGE HAVE INCREASED DRAMATICALLY  WITH ENORMOUS IMPACTS ON ECOSYSTEM SERVICES (E.G.  BIODIVERSITY  WATER SUPPLY  CARBON SEQUESTRATION/EMISSIONS  LOSS AND EXPANSION OF AGRICULTURAL LAND  ETC.). HENCE  ACCURATE INFORMATION RELATED TO CHANGES IN LAND USE AND LAND COVER IS ESSENTIAL FOR BOTH MANAGING NATURAL RESOURCES AND FOR UNDERSTANDING THE ECOLOGICAL  BIOPHYSICAL  AND RESOURCE FOOTPRINT OF SOCIETY. WHILE A NUMBER OF GLOBAL LAND COVER PRODUCTS HAVE BEEN DEVELOPED  NEARLY ALL OF THESE DATA SETS ARE BASED ON COARSE SPATIAL RESOLUTION REMOTE SENSING (I.E.  300-500 METERS)  WHICH IS MUCH COARSER THAN THE SCALE AT WHICH MOST LAND COVER  LAND USE  AND LAND COVER CHANGE OCCUR. FURTHER  NO CURRENT PRODUCTS PROVIDE ACCURATE AND COMPREHENSIVE INFORMATION RELATED TO GLOBAL LAND COVER CHANGE  WHICH IS CRITICAL FOR MANY APPLICATIONS. HENCE  CURRENTLY AVAILABLE PRODUCTS DO NOT MEET THE NEEDS OF THE LARGE  DIVERSE  AND GROWING COMMUNITY OF BASIC AND APPLIED SCIENTISTS WHO REQUIRE BETTER QUALITY  HIGHER RESOLUTION  AND MORE TIMELY INFORMATION RELATED TO GLOBAL LAND COVER  LAND USE  AND LAND COVER CHANGE. TO ADDRESS THIS NEED  WE PROPOSE TO CREATE A GLOBAL LAND COVER  LAND USE  AND LAND COVER CHANGE (GLCUC) DATA RECORD BASED ON LANDSAT IMAGERY THAT WILL PROVIDE HIGH-QUALITY REPRESENTATION OF CONTEMPORARY GLCUC  ALONG WITH RETROSPECTIVE CHARACTERIZATION OF GLCUC AT ANNUAL TIME STEPS FROM 2001 TO 2020. THE GLCUC DATA RECORD THAT WE PROPOSE LEVERAGES DECADES OF COMBINED EXPERIENCE BY THE PROPOSAL TEAM DEVELOPING ALGORITHMS AND DATA SETS IN SUPPORT OF LOCAL-TO-GLOBAL SCALE MAPPING OF LAND COVER  LAND USE  AND LAND COVER CHANGE. TO CREATE THIS DATA RECORD WE WILL PARTNER WITH THE UNITED STATES GEOLOGICAL SURVEY  WHO HAVE PRIME RESPONSIBILITY FOR PROCESSING AND DISTRIBUTION OF LANDSAT DATA AND EXTENSIVE EXPERIENCE CREATING OPERATIONAL AND VALIDATED LAND COVER MAPS FOR THE UNITED STATES. AS PART OF OUR VALIDATION EFFORT WE HAVE RECRUITED A TEAM OF INTERNATIONAL EXPERTS WHO WILL HELP US COMPILE VALIDATION DATA AND QUANTIFY PRODUCT UNCERTAINTIES. FINALLY  TO ENSURE THAT THE USER COMMUNITY IS ABLE TO EASILY ACCESS THE GLCUC DATA RECORD  WE PROPOSE TO PARTNER WITH THE LAND PROCESSES DISTRIBUTED ACTIVE ARCHIVE CENTER (LP-DAAC) TO ARCHIVE AND DISTRIBUTE RESULTS FROM THIS EFFORT. ONCE COMPLETE  THE DATA SETS DEVELOPED THROUGH THIS PROJECT WILL PROVIDE ANNUAL HIGH-QUALITY MAPS OF 21ST CENTURY GLOBAL LAND COVER  LAND USE  AND LAND COVER CHANGE AT 30-M SPATIAL RESOLUTION  ALONG WITH DETAILED CHARACTERIZATION OF PRODUCT ACCURACY.","funder_award_id":"80NSSC18K0994","funder_id":"https://openalex.org/F4320306101","funder_display_name":"National Aeronautics and Space Administration"},{"id":"https://openalex.org/G804835566","display_name":"AGRICULTURE OCCUPIES 38% OF EARTH S ICE-FREE LAND SURFACE  OF WHICH NEARLY 70% IS USED FOR ANIMAL PRODUCTION (FOLEY ET AL.  2011). ALTHOUGH RANGELANDS OCCUPY A DISPROPORTIONATE SHARE OF AGRICULTURAL LAND  THEIR PRODUCTIVITY AND RESILIENCE ARE RELATIVELY UNDERSTUDIED COMPARED TO CROPLANDS (FOLEY ET AL.  2011; MUELLER ET AL.  2012; RAMANKUTTY ET AL.  2002). LACK OF UNDERSTANDING REGARDING THE DYNAMICS AND VULNERABILITIES OF GLOBAL RANGELANDS REPRESENTS A KEY KNOWLEDGE GAP BECAUSE RANGELAND ECOSYSTEMS ARE HEAVILY MANAGED BY HUMANS AND PLAY AN INCREASINGLY IMPORTANT ROLE IN LOCAL AND GLOBAL ECONOMIES. AS A RESULT OF IMPROVING SOCIO-ECONOMIC CONDITIONS IN THE DEVELOPING WORLD  BY 2030 GLOBAL MEAT AND MILK CONSUMPTION ARE PROJECTED TO INCREASE BY 68% AND 57%  RESPECTIVELY  RELATIVE TO 2000 (STEINFELD&GERBER  2010). OUR ABILITY TO INTENSIFY RANGELAND USE TO SATISFY INCREASED DEMAND WHILE DECREASING ENVIRONMENTAL IMPACT DEPENDS ON RANGELAND SENSITIVITY TO PERTURBATIONS CAUSED BY CLIMATE CHANGE. TO ADDRESS THIS KNOWLEDGE GAP  THE MAIN GOAL OF THE PROPOSED RESEARCH IS TO DEVELOP AN INTEGRATED OBSERVATION AND MODELING FRAMEWORK THAT EXPLOITS REMOTE SENSING  METEOROLOGICAL DATA SETS  AND LAND USE AND LAND COVER CHANGE INFORMATION TO IMPROVE OUR CAPABILITY TO MONITOR AND MANAGE THE LONGTERM SUSTAINABILITY OF THIS GLOBALLY EXTENSIVE  CLIMATE SENSITIVE  AND SOCIETALLY-CRITICAL LAND USE. THIS STUDY OF A COUPLED HUMAN-NATURAL SYSTEM WILL LEVERAGE REMOTE SENSING DATA SETS PRODUCED BY NASA TO QUANTIFY THE SENSITIVITY OF RANGELANDS TO CLIMATE VARIABILITY AND ANTHROPOGENIC DRIVERS  AND WILL IMPROVE OUR ABILITY TO MONITOR RANGELAND EXPANSION AND DEGRADATION. IN ADDITION TO ADDRESSING A CRITICAL KNOWLEDGE GAP  MY STUDY IS WELL-ALIGNED WITH NASA EARTH SCIENCE DIVISION S FOCUS ON CHALLENGES RELATED TO LARGE-SCALE GLOBAL ENVIRONMENTAL CHANGE  AND WILL CONTRIBUTE IMPORTANT NEW INFORMATION AND UNDERSTANDING TO BOTH FOOD SECURITY AND CLIMATE CHANGE
