Click on the interactive map (top) to display maps of land health indicators and vegetation performance diagnostics. Shift+drag a window in the map to zoom into your area of interest. Click and drag on the map to pan/move to a different location.
Once you click on the map, a set of indicators are extracted for a 25 square km area around where you clicked. You can explore these indicators below.
The colors of the boxes indicate whether the indicator in question represents a risk. Red or Orange = “Warning!”; Blue = “OK!”
Soil erosion is an important indicator of land health. It can be the result of a number of processes, including:
inherent soil properties (e.g. high pH)
poor drainage or infiltration capacity
When erosion is severe, it leads to the loss of productive topsoil and also the loss of seed stocks in the soil, especially for grasses. The result is that the grasses do not grow back even when there are good rains.
Shows predictions of erosion for an area around the point you clicked on in the map (TOP). Red indicates erosion >75%, which is very high. Black indicates no/low erosion.
Shows the distribution of erosion values within the circle on the erosion map.
Soil pH is an important indicator of soil health. In the case of Turkana, soils have inherently high pH values. When pH values are higher than 7.5, the soil is generally considered alkaline. At values higher than 8 there is considerable risk of salinisation.
Shows predictions of pH for an area around the point you clicked on in the map (TOP). Red indicates low erosion (<5); green-blue between 5 and 7.5; purple higher than 7.5.
Soil organic carbon (SOC) is an important indicator of soil health, but also regulates a number of other ecosystem functions. These include hydrology (e.g. infiltration capacity). When SOC values are lower than 15 g/kg, this is generally considered low SOC, however it is when values drop below 5 g/kg that we have critically low SOC in the soil.
Shows predictions of SOC for an area around the point you clicked on in the map (TOP). Yellow indicates low SOC (<5) while brown shows higher SOC.
Shows the distribution of SOC values within the circle on the SOC map. The vertical red line shows the 15 g/kg threshold.
The boxplot on the left shows a summary of livestock numbers aggregated to village level, based on the HSNP data. You can aggregate the data further by selecting administrative units from the dropdown menu.
