dc.description.abstractEswatini became a signatory to the Ramsar Convention on the 15th of June, 2013. To date, the country does not have a national wetland inventory. This study applies a newly developed wetland mapping technique (produced in South Africa) to Eswatini, to provide baseline information on the potential distribution of wetlands across the country. Results of this study show that when applying the mapping technique as it was applied in South Africa, watercourses (rivers, drainage lines, and riparian zones) are more frequently mapped than true wetlands. Given that Eswatini currently uses the broad Ramsar definition of a wetland, the potential wetland map produced in this study is well suited to identify wetlands falling under such definition. However, the technique does not suffice where a more specific definition for wetlands is used. To improve the initial potential wetland map, this study made use of data, obtained from 2 000 points distributed across the initial wetland map, by classifying areas with the highest potential of being wetlands into hydrogeomorphic units. Results indicate that the methods used to improve the initial map areable to distinguish watercourses with a higher potential of being a true wetland and identify certain hydrogeomorphic units. This method can therefore be used to provide baseline data of potential wetland distribution for countries that do not possess the means, or attribute data to produce a comprehensive wetland map.en_US
