Currently, southern Louisiana faces extreme land loss that could reach an alarming rate of about one football sized swath of land every hour. The combined effect of land subsidence and predicted sea level rise threaten the culture and livelihood of the residents living in this region. As the most vulnerable coastal population in Louisiana, the communities of south Terrebonne Parish are called to adapt by accommodating, protecting, or retreating from the impacts of climate change. For effective preparation planning, the state of Louisiana needs to 1) understand the adaptation preferences and responses of these residents and 2) involve these vulnerable communities in adaptation related decision making. The study uses a survey-based methodology to analyze current adaptation preferences. Findings suggest that protection is the preferred adaptation response. The present study additionally uses participatory techniques to develop a land loss awareness mobile application to illustrate the importance and benefits of community collaboration.
