Sustainable development requires clean water. In Sweden, water supply has historically been good, but a changed climate may alter that situation. Islands such as oland and Gotland, which already have a strained water situation due to their location and bedrock, can be useful case studies for understanding how industries adapt and overcome obstacles in changing behaviour to be more sustainable. Focus groups and a postal questionnaire were conducted to study the water shortage mitigations of the tourism and agriculture industries. The results indicated four salient steps for these industries: awareness/knowledge, responsibility, behaviour and mitigation measures. While awareness was high among all respondents, the level of knowledge varied. Both the tourism and agriculture industries acknowledged their own responsibility but primarily placed the responsibility on each other and on other actors. All respondents had ideas about what behaviours needed to be changed in others, but not as much about their own behaviours, which is a natural consequence of the transfer of responsibility. Finally, there were many ideas for mitigation measures with the agricultural industry focusing on traditional approaches such as irrigation ponds and collecting rainwater, and the tourism industry having more innovative ideas such as re-circulating water and behaviour changes but had not progressed as far in their implementation. This study has shown that industries have different prerequisites and that providing them with tools to help them use preventive measures could speed up the transition to a more sustainable future.
