6 Vulnerability and Adapta:on (IPCC, 2007) Vulnerability: the degree in which a system is suscep5ble to, and unable to cope with, adverse effects of climate change, including climate variability and extremes. Adapta5on: Ini5a5ves and measures to reduce the vulnerability of natural and human systems against actual or expected climate change effects.

7 Vulnerability and Adapta:on (cont.) Small Island Developing Na5ons (SIDS) have been iden5fied as more vulnerable to the nega5ve effects of climate change. Most SIDS are not big GHG emilers, yet are facing some of the most disastrous consequences. Geographical, poli5cal social, and economic characteris5cs contribute to their vulnerability Adapta5on measures are more strongly needed than mi5ga5on,.

8 Challenges for small island na:ons in the face of climate change (UNEP, 2008) High dependence on imports High reliance on fragile ecosystems Limited land and freshwater resources Lack of economies of scale Special vulnerability to sea- level rise and natural disasters

9 Why work with Caribbean island ci:es? Capital ci5es are o_en the main social, economic, and cultural centres of their island na5ons. There is a need to develop further analysis focusing on the role of ci5es and their vulnerability to the expected impacts. Ci5es on Caribbean islands can benefit form assessment tools against climate change impacts, in order to formulate sound adapta5on measures.

11 Aim Analyze the climate change vulnerabili5es in Caribbean island s capital ci5es and provide poten5al adapta5on measures

12 Objec:ves 1. Determine climate impacts in Caribbean Island and its capital ci5es and how comparable governments are dealing with similar issues 2. Create a Climate Change Urban Vulnerability Index (CCUVI) to help establish varia5ons in vulnerability to climate change impacts.

13 Objec:ves (cont) 3. Use the CCUVI to iden5fy areas most affected by climate change impacts and develop a series of adapta5on measures for the different affected areas 4. Develop a series of norma5ve and opera5onal recommenda5ons to direct efforts, resources, and capabili5es effec5vely

14 Methodology Background Analysis Vulnerability Index Crea5on Assessment Analysis

15 Case studies: San Juan, Puerto Rico St. George s, Grenada

16 Phase 1: Background Analysis San Juan, Puerto Rico Founded: 1508 Area: sq. km Popula5on: 434, 374 hab. Avg. temp: 25.6 C Avg. rainfall: 1,289.3mm

17 Phase 1: Background Analysis (cont.) St. George s, Grenada Founded: 1650 Area: sq. km. Popula5on: 3,629 hab. (2001) Average temp.: 27.5 C Average rainfall: 1,138.2 mm

18 Associated climate hazards for Caribbean islands and its ci:es The Caribbean has been a region vulnerable to the effects of many climate hazards. Climate change is expected to exacerbate these events

19 Phase 2: Crea:ng the CCUVI Looking at elements of vulnerability Exposure, Sensi5vity, Adap5ve Capacity Looking at dimensions of the city Socio- demographic, natural environment, built environment Data availability and per5nence, produced mainly by respec5ve local or na5onal governments

20 Phase 2: Crea:ng the CCUVI (cont) Climate Change Urban Vulnerability Index (CCUVI) Components # Indicator Justification 1 vulnerable population Population that are more needed of asssistance and care during climate hazards 2 steep slopes Areas prone to be affected by landslides and\or high winds 3 flood zones Areas prone to be affected by flooding events 4 average mean temp. changes Areas that are presenting variability in mean air temperature 5 building density Concentration of structures, communities and more urbanized areas 6 poverty levels Population group that are more susceptible to the effects of climate impacts 7 average rainfall variablity Areas that are expected to be more sensitive to rainfall variability 8 population density Concentration of population around the city will be priority areas for adaptative measures 9 Average income Families that have more economic means to adapt towards the expected impacts 10 education levels Population that have less education levels are in need of more assistance for adaptation measures 11 green spaces Green & Blue spaces provide benefits for climate adaptation 12 shelters Check the availability and location of shelters during climate hazard events 13 hospital occupancy 14 road density Check the capacity of the city to attend population with health issues during emergencies in climate impacts Show the variation in connectivity of the city, particularly important for mobilizing people, goods and assistance.
