Potential distribution of GAS
Whilst there was nowhere in Kenya that was not suitable for GAS, the
extent to which areas were suitable varied significantly across the
country. Particularly high areas of suitability were found to the
South-East of the country, along the Tana river and the coast near
Mombasa (Figure 4). All three survey areas in this current study were
modelled as having high suitability for GAS. However, the occurrence can
only be realized in presence of rivers or irrigation water. Whilst no
GAS were found in Tana River and Kisumu counties, the high suitability
of these areas highlights the potential for further widespread
distribution of GAS into these areas.
Across the region, the countries with the highest suitability for GAS
were Malawi, Madagascar and Uganda. Mozambique, Tanzania and Ethiopia
also had areas of high suitability, but these were more concentrated in
specific areas of the country. In comparison, suitability across Sudan
and Somalia was very low (Figure 5).
