However, mapping these particular land use patterns in rural heterogeneous landscapes is challenging because their potential signatures on the landscape cannot be positively identified without fine-scale land use data for validation. Using field-mapped resource areas and household survey data from participatory mapping research, we combined various Landsat-derived indices with ancillary data associated with human habitation to model the intensity of grazing and NTFP collection activities at 100-m spatial resolution. The study area is situated centrally within a transboundary southern African landscape that encompasses community-based organization (CBO) areas across three countries. We conducted four iterations of pixel-based random forest models, modifying the variable set to determine which of the covariates are most informative, using the best fit predictions to summarize and compare resource use intensity by resource type and across communities. Pixels within georeferenced, field-mapped resource areas were used as training data. All models had overall accuracies above 60% but those using proxies for human habitation were more robust, with overall accuracies above 90%. The contribution of Landsat data as utilized in our modeling framework was negligible, and further research must be conducted to extract greater value from Landsat or other optical remote sensing platforms to map these land use patterns at moderate resolution. We conclude that similar population proxy covariates should be included in future studies attempting to characterize communal resource use when traditional spectral signatures do not adequately capture resource use intensity alone. This study provides insights into modeling resource use activity when leveraging both remotely sensed data and proxies for human habitation in heterogeneous, spectrally mixed rural land areas.<\/jats:p>","DOI":"10.3390\/rs13040631","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T16:12:10Z","timestamp":1613146330000},"page":"631","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Modeling Community-Scale Natural Resource Use in a Transboundary Southern African Landscape: Integrating Remote Sensing and Participatory Mapping"],"prefix":"10.3390","volume":"13","author":[{"given":"Kyle D.","family":"Woodward","sequence":"first","affiliation":[{"name":"Department of Earth and Ocean Sciences, University of North Carolina Wilmington, 601 S College Road, Wilmington, NC 28403, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6591-7237","authenticated-orcid":false,"given":"Narcisa G.","family":"Pricope","sequence":"additional","affiliation":[{"name":"Department of Earth and Ocean Sciences, University of North Carolina Wilmington, 601 S College Road, Wilmington, NC 28403, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9328-3753","authenticated-orcid":false,"given":"Forrest R.","family":"Stevens","sequence":"additional","affiliation":[{"name":"Department of Geography and Geosciences, Lutz Hall, University of Louisville, Louisville, KY 40292, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4898-1587","authenticated-orcid":false,"given":"Andrea E.","family":"Gaughan","sequence":"additional","affiliation":[{"name":"Department of Geography and Geosciences, Lutz Hall, University of Louisville, Louisville, KY 40292, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0527-058X","authenticated-orcid":false,"given":"Nicholas E.","family":"Kolarik","sequence":"additional","affiliation":[{"name":"Department of Geography and Geosciences, Lutz Hall, University of Louisville, Louisville, KY 40292, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0774-2034","authenticated-orcid":false,"given":"Michael D.","family":"Drake","sequence":"additional","affiliation":[{"name":"Environmental Studies Program, Sustainability, Energy, and Environment Community, University of Colorado Boulder, 4001 Discovery Drive, Boulder, CO 80303, USA"}]},{"given":"Jonathan","family":"Salerno","sequence":"additional","affiliation":[{"name":"Department of Human Dimensions of Natural Resources, Graduate Degree Program in Ecology, Colorado State University, Campus Box 1480, Fort Collins, CO 80523-1480, USA"}]},{"given":"Lin","family":"Cassidy","sequence":"additional","affiliation":[{"name":"Okavango Research Institute, University of Botswana, P\/Bag 285, Maun, Botswana"}]},{"given":"Joel","family":"Hartter","sequence":"additional","affiliation":[{"name":"Environmental Studies Program, Sustainability, Energy, and Environment Community, University of Colorado Boulder, 4001 Discovery Drive, Boulder, CO 80303, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7610-8646","authenticated-orcid":false,"given":"Karen M.","family":"Bailey","sequence":"additional","affiliation":[{"name":"Environmental Studies Program, Sustainability, Energy, and Environment Community, University of Colorado Boulder, 4001 Discovery Drive, Boulder, CO 80303, USA"}]},{"given":"Henry Maseka","family":"Luwaya","sequence":"additional","affiliation":[{"name":"Department of National Parks and Wildlife, Private Bag 1, Kafue Road, Chilanga, Zambia"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"139","DOI":"10.1023\/A:1023630924100","article-title":"Rainfall Variability and Changes in Southern Africa during the 20th Century in the Global Warming Context","volume":"29","author":"Fauchereau","year":"2003","journal-title":"Nat.
