studies found a relation to temperature and/or precipitation for dengue47 but other results seemed to be neither consistent nor significant. This can be traced back to a large importance of non-climatic reasons for the spread of the illness48 but also to the varying conditions in the country, in particular for the precipitation which is often discussed as a factor. • Noting limited knowledge regarding the spatial distribution of vulnerability to climate change, most vulnerable areas found are drought prone areas housing populations strongly dependent on agricultural yields as food and income source. For regions further situated near the coast, additional risks contribute to an even higher vulnerability. All the coastal areas where coral reefs and mangroves are still present should be regarded as vulnerable. The same is true for the corresponding communities nearby. The possible disappearance of an ecotype seems to be of particular importance as the reversal is almost impossible. Much detailed knowledge regarding the spatial distribution can potentially be found in the listed case studies of Table 2 (next page).                                                                                                                 47 G.L.S.
