Title |
Monitoring of sustainable land management using remotely sensed vegetation cover, NSW, 2010-2021 |
Abstract |
This dataset provides maps and data that identify the sustainability of land management over NSW over the period 2010 to 2021. It is based on a new method for monitoring sustainable land management using widely available remotely sensed data: MODIS fractional vegetation cover data. The method relies on maintaining sufficient vegetation cover to prevent hillslope water erosion beyond tolerable soil erosion targets. The targets were based on long-term natural erosion rates plus a small constant and are spatially and temporally variable. Results were initially generated for individual months then were amalgamated into yearly sustainable land management indices (SLMI), presented as raster maps (100 m spatial resolution). These results were further stratified by land uses and natural resource management regions, revealing useful data and trends. Data on rainfall patterns over the preceding 12 months (relative rainfall index, RRI) can aid interpretation of the results. The method and sample results were presented in an international journal paper: Gray et al. (2023). Monitoring of sustainable land management using remotely sensed vegetation cover and variable tolerable soil erosion targets across New South Wales, Australia. https://doi.org/10.1111/sum.12876 |

Lineage |
In overview, the broad approach adopted was to assess whether vegetation cover across NSW lands was sufficient to prevent hillslope water erosion beyond tolerable levels. The tolerable erosion rate has two components: (i) spatially variable long-term natural erosion rates (varies for each pixel) plus (ii) a small additional tolerable erosion rate (constant across all lands). The sum of these two components gives the required spatially variable tolerable erosion rates across the State. Where the actual vegetation cover for each month (derived from MODIS satellite data) is more than the vegetation cover required for effective prevention of non-tolerable erosion, the land is considered to be sustainably managed for that month. Monthly results are combined into a yearly index, the sustainable land management index (SLMI). Recent rainfall conditions are also qualitatively considered through a relative rainfall index (RRI) when interpreting the results. The process is presented and described in more detail in the published journal paper (Gray et al 2023: https://doi.org/10.1111/sum.12876) |
