Net primary productivity (NPP) is the net amount of carbon assimilated after photosynthesis and autotrophic respiration over a given period of time (Clark et al. 2001) and is typically represented in units such as kg/ha/yr. NPP is a variable time consuming and costly to estimate, for that reason, we rely on remotely sensed information to derive indicators of NPP.&lt;/span&gt;&lt;/p&gt;

In Trends.Earth we make use of bi-weekly products from MODIS and AVHRR to compute annual integrals of NDVI (computed as the mean annual NDVI for simplicity of interpretation of results). These annual integrals of NDVI are then used to compute each of the productivity indicators explained below.&lt;/span&gt;&lt;/p&gt;

Trends.Earth computes a linear regression at the pixel level to identify areas experiencing changes in primary productivity for the period under analysis. A Mann-Kendall non-paremetric significance test is then applied, considering only significant changes those that show a p-value ≤ 0.05. Positive significant trends in NDVI would indicate potential improvement in land condition, and negative significant trends potential degradation.&lt;/span&gt;&lt;/p&gt;

The indicator is computed as follows:&lt;/span&gt;&lt;/p&gt;
&lt;ol style=&quot;margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; -qt-list-indent: 1;&quot;&gt;&lt;li style=&quot; font-family:'Ubuntu'; font-size:11pt;&quot; style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Define the baseline period (historical period to which to compare recent primary productivity).&lt;/li&gt;

It is recommended to use a 3-year to avoid annual fluctuations related to climate.&lt;/li&gt;
&lt;li style=&quot; font-family:'Ubuntu'; font-size:11pt;&quot; style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;For each pixel, use the annual integrals of NDVI for the baseline period to compute a frequency distribution. In case the baseline period missed some extreme values in NDVI, add 5% on both extremes of the distribution. That expanded frequency distribution curve is then used to define the cut-off values of the 10 percentile classes.&lt;/li&gt;

Assign to the mean NDVI for the baseline period the number corresponding to that percentile class. Possible values range from 1 (lowest class) to 10 (highest class).&lt;/li&gt;
&lt;li style=&quot; font-family:'Ubuntu'; font-size:11pt;&quot; style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Compute the mean NDVI for the comparison period, and determine the percentile class it belongs to. Assign to the mean NDVI for the comparison period the number corresponding to that percentile class. Possible values range from 1 (lowest class) to 10 (highest class).&lt;/li&gt;

If the difference is ≥ 2, that pixel would indicate a recent improvement in terms of primary productivity. Pixels with small changes are considered stable.&lt;/li&gt;&lt;/ol&gt;

Trends.Earth uses the unique combination of soil units (soil taxonomy units using USDA system provided by SoilGrids at 250m resolution) and land cover (full 37 land cover classes provided by ESA CCI at 300m resolution) to define this areas of analysis. The indicator is computed as follows:&lt;/span&gt;&lt;/p&gt;

From this distribution determine the value which represents the 90th percentile (we don’t recommend using the absolute maximum NDVI value to avoid possible errors due to the presence of outliers). The value representing the 90th percentile will be considered the maximum productivity for that unit.&lt;/li&gt;

&lt;li style=&quot; font-family:'Ubuntu'; font-size:11pt;&quot; style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;If observed mean NDVI is lower than 50% than the maximum productivity, that pixel is considered potentially degraded for this indicator.&lt;/li&gt;&lt;/ol&gt;
