Land Productivity Dynamics (LPD) maps based on approaches recommended by the United Nations Convention to Combat Desertification (UNCCD) for the Brazilian Semiarid Region (BSR).

Maps of the land productivity dynamic (LPD) based on approaches recommended by the United Nations Convention to Combat Desertification (UNCCD) for the Brazilian Semiarid Region for the period 2001-2015. LPD from Trends.Earth (TE), LPD from the Joint Research Center (JRC-LPD), and LPD from the Food and Agriculture Organization – World Overview of Conservation Approaches and Technologies (FAO-WOCAT LPD). In addition, TE-based LPD with climate correction based on Rain Use Efficiency (RUE), Residual Trend Analysis (RESTREND), and Water Use Efficiency (WUE) calculated using the procedures described in the second version of the Good Practice Guidance for SDG Indicator 15.3.1. The annual LCLU maps from the MapBiomas project at 30 m spatial resolution for 2001 and 2015, and the 16-day MOD13Q1 NDVI dataset from 2001 to 2015 were used as inputs. ********************** A total of seven GeoTIFF files in Geographic Tagged Image File Format (GeoTIFF) format are provided at 250 m spatial resolution. Coding for the LPDs. Value Meaning -32768 No data 1 Declining 2 Moderate decline 3 Stressed 4 Stable 5 Increasing Funding: this study was undertaken as part of the Satellite Desertification Monitoring Program in the Brazilian Semiarid Region [Grant Number 403223/2021-0] supported by the CNPq. It also had the support of Capes, through Notice no. 28/2022 – PDPG Social Vulnerability & Human Rights [Grant Number 88881.705050/2022-01].本数据集涵盖2001-2015年巴西半干旱区基于联合国防治荒漠化公约（United Nations Convention to Combat Desertification, UNCCD）推荐方法生成的土地生产力动态（Land Productivity Dynamic, LPD）地图。数据来源包含三类：Trends.Earth（TE）产出的LPD、联合研究中心（Joint Research Center, JRC）的LPD（JRC-LPD），以及联合国粮食及农业组织-保护措施与技术全球概览（Food and Agriculture Organization – World Overview of Conservation Approaches and Technologies, FAO-WOCAT）的LPD（FAO-WOCAT LPD）。 此外还提供经气候校正的TE-LPD数据，该校正方案结合了降雨利用效率（Rain Use Efficiency, RUE）、残余趋势分析（Residual Trend Analysis, RESTREND），以及依据《可持续发展目标指标15.3.1良好实践指南》第二版所述流程计算得到的水分利用效率（Water Use Efficiency, WUE）。 本数据集以2001年与2015年30米空间分辨率的MapBiomas项目年度土地覆盖与土地利用（Land Cover and Land Use, LCLU）地图，以及2001至2015年的16天合成MOD13Q1归一化植被指数（Normalized Difference Vegetation Index, NDVI）数据集作为输入数据源。 ********************** 本次共提供7份空间分辨率为250米的地理标记图像文件格式（Geographic Tagged Image File Format, GeoTIFF）数据。 土地生产力动态的编码规则如下：值-32768代表无数据；1代表下降；2代表中度下降；3代表受胁迫；4代表状态稳定；5代表上升。 资助说明：本研究作为巴西半干旱区卫星荒漠化监测项目的一部分实施，获得了巴西国家科学技术发展委员会（Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq）的资助（项目编号：403223/2021-0），同时得到巴西高等教育人员发展协调局（Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, Capes）通过第28/2022号公告-PDPG社会脆弱性与人权项目的支持（项目编号：88881.705050/2022-01）。
