Note:
         i) Each node represents a key element and its corresponding SDG target(s) for achieving sustainable development at the river basin scale.
         ii) Each link has a direction indicated by an arrow showing the causal relationship from one node to another.
         iii)The value (between -1 and 1) over the line (by putting the cursor on the line) indicates the strength of the link between the pair targets. When the links cannot be quantified due to data unavailability, qualitative results are provided
             based on an expert survey. For qualitative results, “S” indicates a strong link and “W” indicates a weak link.
         iv) Green links indicate positive relationships between the pairs of nodes, red links indicate negative relationships, and blue links indicate either positive or negative relationships depending on the conditions.
         v) v) Solid links indicate the quantified results based on the data of the location. For data source, please see the PDF file here. Dotted links indicate the qualitative results based on an expert survey, which are applied instead of the quantified data due to its              unavailability. See Methodology for details.
