The Vulnerabilities Of Small Island Developing States Environmental Sciences Essay

The Vulnerabilities Of smoothish Island growth States Environmental Sciences actSmall Island develop States (cot death) comprise small islands and low-lying coastal countries located across the Indian, peace-loving and Atlantic Oceans and Caribbean Sea. While geographical, climatic, cultural and socio- frugal dissimilarities exist between these nations, they face common festering const raints and vulnerabilities to Climate transplant.Growth and build upment of infant death is restricted by factors much(prenominal)(prenominal) as limited resources, remoteness and volatile hold up patterns. Small populations and remoteness besides lead to high transportation and communication costs and minimal opportunity to make believe economies of scale thereby inducing expertness to external shocks. SIDS excessively generally possesses a unplumbed colony on imported petroleum products. High electricity prices therefore also present constraints to economic and social tuition effo rts. Consequentially, eleven SIDS nations ar also recognised by the United Nations as to the lowest degree Developed Countries (LDC).The environmental impact of homosexual operation is increasingly beingness recognised across the globe. Greenhouse Gas (GHG) emissions life-sizedly from the burning of fossil fuels and deforestation construct signifi empennagetly summation everyplace the last half a century, jumper cable to the Climate Change phenomenon. Symptomatic transports in clime be already being realised, with increasing temperatures, altering rainfall patterns, procession sea-levels and increased frequency and intensity of inborn disasters causing social, economic and environmental issues across the globe. While SIDS provide a minimal portion to world(prenominal) GHG emissions, they be amongst the most vulnerable to its effects. The size of these island states makes them particularly susceptible to climatic variations and extreme events as large areas or eve n entire islands can be directly affected. The consequential economic environmental and social injure can therefore be extensive, without the option of intra-national relief. Key sector such as tourism and agriculture are under proficient threat patch in few mint the very existence of more than island states is at riskiness.Common characteristics of SIDS not except enhance their susceptibility to experiencing a changing clime but give them a low capacity to adapt to such qualify. Already experiencing many socio-economic issues such as irrigate and fodder security, intensification of such issues due to humor change may make these countries uninhabitable.This paper aims to identify the major vulnerabilities of SIDS to impending Climate Change and make the role that developed nations should play in assisting their survival.NATURAL mode IN SIDS AND PROJECTED CLIMATE CHANGESAcross the globe, the effects of Climate Change are already being observed, with SIDS undoubtedly being affected. Sea show up temperatures have been increasing by 0.1C per decade in the oceans where most SIDS are located (45), bandage annual and termal ocean surface and island air temperatures have increased from 0.6C to 1.0C since 1910 throughout a large part of the South Pacific (46). Studies over the degree 1971 to 2004 have also suggest warming to be occurring in the Caribbean, Indian Ocean and Mediterranean regions, with trends ranging from 0C to 0.5C per decade (47).Warming sea temperatures leads to expanding oceans and rising sea levels. This is a key annoyance for SIDS with the entire Pacific region experiencing a mean rise of +0.77 mm per year (53), sequence sea-levels in the Caribbean region increase on average by 1mm per year. Local conditions mean there is wellnessy variation between or even within individual island states. For example, different tectonic movements across the expanse of Trinidad has lead to rises of about 1mm per year along the west coast, season the south is experiencing an increase of approximately 4mm all(prenominal) year (54).Changing trends in extreme temperatures have also been observed. The annual number of hot eld and warm nights in the South Pacific and Caribbean regions has shown increasing trends, as well as a coition decrease in the annual number of cool age and cold nights (48, 49).The climate of SIDS is powerfully influenced by the ocean-atmospheric interactions. The El Nio Southern Oscillation and decadal variability play a preponderant role in experienced periods of drought and high rainfall and the common coevals of tropical cyclones and storms in small island regions. Climate Change is already and expected to continually enhance such extreme weather events. Rainfall patterns are becoming much than variable. The Caribbean especially has experienced less consecutive dry days man heavy rainfall events are becoming more frequent (50). These changes are barfed totally to get worse. The intensit y and frequency of cyclnes and tropical storms is also expected to increase. Since 1970 the intensity and duration of storms has increased leading to a greater number reaching category 4 and 5 (51).IMPACTS FROM CLIMATE CHANGE disrespect being heavily reliant on fossil-fuel based energy, in comparison to developed and other underdeveloped states SIDS use a relatively modest amount of fossil fuels. Consequentially their greenhouse blow out emissions remain low, accounting for less than 1% of global emissions (Table. 1). Furthermore, the annual emissions from the Pacific islands is .96 tonnes of carbon dioxide per capita, equating to only 25% of the worldwide average per person. SIDS thus hold minimal responsibility for the current climate change, yet in a sad irony they are likely to be the most ill impacted.Table 1. Total Greenhouse Gas Emissions 2003 Selected Countries (http//cait.wri.org)Already susceptible to forage and peeing security and clement health, climate change is likely to exacerbate such socio-economic issues.Water ResourcesPoor water supply tonus and water stress is common in SIDS. High rainfall and drought periods associated with El Nio episodes significantly impact water security of small islands, while factors such as limited size, geology and topography make their water resources especially sensitive variations in climate. Inadequate infrastructure such as dams, reservoirs and water distribution networks drift advertize issues for water security in many SIDS.Small island nations often show a watertight dependence on rainfall. Tuvalu and several other countries in the Pacific rely on rainfall as their principal freshwater source Dominica, in the Caribbean and the Seychelles in the Indian Ocean, show almost complete dependence on surface water from streams while many low-lying coral islands and raised atolls are squeeze to rely on groundwater due to unsubstantial freshwater lenses. Reduced rainfall, a likely consequence of climat e change, constrains the amount of physically harvestable water, reduced river flow and slowed recharge of freshwater lenses. Hence the ability to meet rustic and domestic water demands is severely compromised. low-lying rise and flooding can also lead to saltwater intrusion and siltation of freshwater systems. Extreme weather events can also increase water taint with serious implications for gentleman health and the incidence of water-borne diseases.Furthermore, a lack of adequate water infrastructure such as dams and reservoirs, results in high runoff during the rainy seasons and consequential losses of surface and stream water to the sea.coastal zonesCoastal areas of small islands are generally the site for major settlements and the centre of economic activity. In the Caribbean more than half the population lives within 1.5km of the shoreline, while islands of the Pacific and Indian Ocean, generally establish their villages on the back terrace or on the land itself. Commu nities and critical infrastructure such as schools, electricity generation plants, fuel storage facilities, police stations and hospitals are therefore in direct risk of rising sea-levels and extreme weather events. In the case of a disaster populations are thereby left without staple fiber social services.Rising sea-levels lead to coastal erosion and in some cases inundation, while physical constipation from hurricanes and cyclones also threaten vital coastal assets and sympathetic lives of small islands. From 1950 to 2004 76% of the reported disasters in the Pacific island region was cyclones with the average cost per cyclone estimated at US$75.7 million (in 2004 value), while the 2004 hurricane season alone caused damage of around US$2.2 one thousand thousand in only four countries the , Grenada, Jamaica and the Dominican Republic.Biodiversity and TourismGeographical isolation has allowed the formation of many unique species, making these islands home to a significant prop ortion of the worlds biodiversity. just, human activity is posing serious threats to the natural ecosystems of SIDS.Extensive deforestation has occurred for infrastructural development and agriculture, with more than one quarter of the small island states demonstrating greatly reduced forest cover. Terrestrial and marine ecosystems are also experiencing increasing degradation and pollution and overexploitation. Coral cover has declined by up to 80% over the last 3 years in reefs of the Caribbean, with pollution, sedimentation and over-fishing has been admonishmined to be largely responsible. Climate Change will have further consequences for biodiversity and the health of natural ecosystems. Apart from the arising environmental concerns, ensuing social and economic issues also follow due to compromised environmental services.Physical damage from more frequent and intense natural disasters presents severe implications for marine and terrestrial biodiversity. Sea-level rise and assoc iated flooding can lead to salinisation of begrimes and adverse effects to mangrove forests. Rises in ocean surface temperature and carbon dioxide concentration further threaten coral reefs, leading to coral bleaching events and decreased calcification rates. Based on project CO2 levels, it has been suggested that the calcification rate of corals could decrease by about 14 per centum to 30 percent by 2050(57). Coral reefs play an important role for small islands, providing key nurseries for fish species, protection of the beach and tourism opportunities.Many SIDS rely on one or few economic activities, with tourism and travel commonly accounting for more than 25% of Gross Domestic Profit (GDP) and in some cases more than 50% (12). Natural disasters and degradation of ecosystems can severely impact this income generation.Changing weather- changing distribution of speciesAgriculture and fisheriesAgriculture is highly valued and depended upon in SIDS for both subsistence requirements and economic development. Many islands but have limited arable land and prime agricultural regions are generally located on the coastal plains. Climate change and associated sea-level rise therefore poses a significant risk of further reduction of available farming land due to inundation and salinisation. Extreme weather events also adversely impact food crops and other livelihood resources. Cyclones, hurricanes and floods can cause irreparable damage while panoptic droughts and shortened growing seasons would also reduce yields. Such events have serious implications for food security while reduced exports of cash crops compromises their foreign exchange earnings and position in world trade.Climate change however is likely to affect varying degrees of economic losses among different island states. Viti Levu, a high island in Fiji, is estimated to have the potential to endure costs in the range of US$23 to 52 million per year by 2050. The low island of Tarawa in Kiribati however f aces annual costs of US$8 to 16 million. These costs would represent only 2-3% of Fijis GDP in 2002 and 17-18% of Kiribatis GDP for the same year (58).Fisheries are also a critical sector in many SIDS, contributing up to 10% of the GDP. The El Nio / La Nina cycle already causes visible variations in tuna catches, demonstrating the sensitivity of fish stocks to climate variability. Climate change poses the risk of stimulating altered migration patterns and the depth of fish stock, affecting the distribution and handiness of fish species with socio-economic consequences.Human HealthGlobal warming may lead to a variety of associated human health issues. Direct threats to human welfare include injuries and fatalities from extreme weather events such as floods, hurricanes and landslides, while increased frequency and duration of heat waves can also be expected to increase the risk of heat stress, indisposition, and respiratory and cardiovascular diseases, especially amongst the elderly .A changing climate can also have indirect implication on human health. Increasing temperatures and changing rainfall patterns may lead to an increase in water and vector-borne diseases. In 2008, there were 247 million cases of malaria worldwide and nearly one million deaths, in general among children. Malaria is most commonly caused by the parasites, carried by mosquitoes. Increasing temperatures and flooding events provide favourable environments for mosquitoes hence climate change is likely to expand the spread of mosquito and the risk of malaria contraction. Variation in precipitation and temperature will also increase the prominence of dengue fever, with such weather patterns attributable several cases in Barbados, Trinidad and Tobago during the period 1980-2000. storm surges and flooding events also heighten water pollution, leading to water-borne diseases such as cholera and the diarrheal diseases caused by organisms such as giardia, salmonella and cryptosporidium. Furthermo re, deceases in rainfall may lead to reduced available freshwater for human use and consumption, increasing the risk of disease. Secondary malnutrition may increase due to declines in water quality and decreases in agricultural productivity.ADAPTATION ACTIONDue to the current accumulation of carbon dioxide in the standard pressure and with recommended emission targets from the IPCC failing to be met by major greenhouse bodge emitters, the effects of Climate Change are requisite (61). Coupled with the severity in which this is predicted to affect Small Island Developing States, it is imperative that adjustive action is taken for the survival of these nations.A number of adaptation initiatives have been implemented by SIDS on a topical anaesthetic scale, often in an ad hoc manner. For example, since Hurricane Ivan, it has become common practice in Jamaica to place concrete blocks on the top of zinc roofs. Typhoon resistant housing has been implemented in the Philippines aft(pren ominal) Typhoon Sisang in 1987 and improved housing design is also evident in Costa Rica and Equador, with elevated houses or a reinforced concrete strip as a foundation so that the bamboo walls do not touch the ground and are protected from fungal deterioration.There are many avenues available to accost water security issues. Promotion of drought tolerant vegetation and establishment of river buffer zones enhances the resilience of rivers and catchment areas. matter water policies can be used to encourage efficient water use, advocating water saving devices, while revision of building codes can work to improve water resource management, by increasing opportunities for rainwater catchments and storage. The Cajete Terrace agro-systems of Mexico provide an innovative example of adaptation measures to enhance water use efficiency and enables food to be sustainably grown on steep erosion prone slopes4. This works by excess water being fed from sloping terraces into tanks (Cajetes). Th e water, which would otherwise not be absorbed into the soil, is collected intimate the cajetes and easily seeps into the surrounding soils after the rain has ended. Eroded nutrient rich soil is also trapped inside of the cajetes and later gathered and distributed into the fields. Adaptable farming systems has also be achieved by African farmers through intercropping, variegation of herds and incomes, such as the introduction of sheep in place of goats4.Climate Monitoring, Forecasting and Early Warning Systems can be an invaluable tool to reduce the impacts of climate change. A National Community Based flood Early Warning System has been effected in the Philippines, allowing predictions and timely responses to possible storm events or flooding. With such equipment, outlooks with lead times of two to six months before the onset of an event may be possible6. sender dispersion probabilities could also be monitored with such warning systems, allowing opportunities for putting inter ventions in place, thereby preventing excessive illness and mortality during disease epidemics such as Malaria6. In terms of food production, these systems enable better clock planting and harvesting, opportunity for informed decision of alternative cultivar or crop use, better planned food storage according to future need, and preparation of alternative food procurement strategies in advance1. This would mean more efficient use of seeds, labour, and other household resources in farming and food procurement. Such systems also display the benefits of regional arrangements pooling resources. Regional management of early warning systems is much more effective in enhancing adaptational capacity than national management.Education and promotion of responsible environmental practices is also necessary, such as upbringing of fishermen and women in sustainable fishing practices and farmers in sustainable land use practices. Land use plans and succeeding enforcement strategies can also be utilised to achieve less destructive environmental practices such as reducing deforestation. Mangrove and coral systems should be protected to maintain their integrity. This can be achieved through reject pollution and restricting development in coastal areas. Controlled coastal development can also background exposure of people and property to coastal erosion and inundation.Relocation programs have been applied in many states to varying degrees. Frequent flooding and erosion necessitated 100 villagers in Lateu Vanuatu to be moved 600m from the coast to higher(prenominal) ground, while Carteret Islanders are being relocated to neighbouring Papua New Guinean island, Bougainville, in response to the excessive impacts of sea-levels rise. reconstruction of groynes, building sand dune fences and beach renourishment (planting of trees along the coast) has also been used to protect the beach pen and mitigate the impact of coastal erosion on communities.Building national and regional a daptive capacity and providing further options for adaptation is an important component of many SIDS adaptive programs. This involves strengthening institutions, policies and regulations and linking adaptive strategies with sustainable development. Hence, many SIDS have identified investment into renewable and non-polluting energy systems as a priority. This would not only reduce climate change inducing greenhouse flatulence emissions, but would promote long energy security.ROLE OF DEVELOPED NATIONSAdaptationThe low emission levels of SIDS means their policy actions are primarily focused on adaptation. However, these countries do not have the capacity to fully parentage the take adaptation. The World Bank has estimated adaptation in developing countries to require between US$10 billion and US$40 billion. Additional resources, including finances and technological knowledge, are therefore required from the worldwide companionship to facilitate SIDS in building their capacity to adapt to a changing climate and develop sustainably.Currently there is no specific fund which addresses the concerns of SIDS in relation to Climate Change. However global funding sources are available to assist with the costs associated with adaptation. The Adaption Fund, the Global Environment Facility (GEF) and The peculiar(prenominal) Climate Change Fund provide fiscal support for projects aimed at reducing vulnerability while increasing adaptive capacities to the adverse effects of climate change. This is generally achieved through technology transfer, economic diversification, investments in non-polluting, efficient and renewable energy and sustainable development with regards to energy, transport, industry, agriculture, forestry and waste management. For SIDS also considered to be LDCs, the Least Developed Countries Fund, established under the UNFCCC is also available with associated National Adaption Programs of Action. These programs of action combine sustainable developme nt and adaption objectives, focusing on water resources, food security and agriculture, disaster preparedness and risk management, coastal zone management and infrastructure, natural resources management and fellowship level adaptation.Some adaptation programs are targeted at duple countries (For example, the GEF-UNDP project Piloting Climate Change Adaptation to Protect Human Health and the GEF-World Bank project on Mainstreaming Adaptation to Climate Change in the Caribbean region ), while others are more specific in their application locality. In executing such adaption programs, it is essential the world(prenominal) intervention is sensitive to the local contexts and requirement of the target island state/s. Projects should ultimately aim to enhance national and region capacity for long-term sustainability and resilience in the face of climate change. Dependence on external assistance must be carefully avoided as with implementation of ignorant hence potentially harmful stra tegies.Valuing traditional knowledge is a critical means of maximising the potential long-term benefits of projects and ensuring their suitability. For example, to assist food security despite peculiar rainfall and cyclones farmers of Timor Island have developed their own varieties of major staple crops. Peru farmers provide another example, using an old-fashioned irrigation draining system waru waru, or raised field agriculture, which makes it possible to bring into production the low-lying, flood-prone, poorly knackered lands. The shallow canals provide moisture during droughts, drainage during the rainy season and also buffer against night-time frosts. The Zai technique in Burkina Faso also provides an example of a cost-effective adaptation measure to enhance productivity4. Farmers dig pits in the soil to collect organic material carried by the wind during the dry season, at the start of the rainy season farmers add organic matter from animals which attracts termite activity re sulting in termite tunnels that can collect rain deep enough that it doesnt evaporate, and thus increasing soil fertility. Incorporating local knowledge and practices into initiatives not only makes communities more likely to adopt adaptive strategies but they also have a greater chance of advantage due to being contextually appropriate.To hold in benefit maximisation, initiatives should be applied on a community level. Local stakeholders and community members should be involved in all stages of the project to ensure all of their ideas and concerns are incorporated into the design and implementation. Local involvement will also enhance capacity building and self-direction of target communities. Positive examples of this occurring include in Bangledesh where volunteers have been trained to help in cyclone warning, evacuation, rescue, first wait on emergency relief and the use of radio communication equipment4. The Caribbean Climate Change Centre was also established through the C aribbean Planning for Adaptation to Climate Change project, allowing climate change concerns to be addressed locally. disdain the efforts of such projects further advances in adaptation capacity and technology transfer is still required. For full acknowledgment of benefits, climate change adaptation must be addressed in conjunction with developmental activities. disaster preparedness, land-use planning, environmental conservation, coastal planning, and national plans for sustainable development complement the objectives of enhancing adaptive capacity. Hence this relationship should be reflected through relevant policies.MitigationClimate Change poses disproportionate impacts across the globe. While their greenhouse gas emissions are insignificant compared to other countries, the future viability or even survival of many Small Island Developing States is severely threatened.High level emitters, especially developed nations such as Australia, therefore have a responsibility to reduce their contribution to Climate Change. Lobbying for such action is challenging for SIDS due to their international representation. SIDS are members of the negotiating coalition of developing countries, Group of 77 and China (G77/China). Unfortunately, some of the largest greenhouse gas emitters among developing countries are also members. Hence these countries present reluctance to reduce GHG emissions because of their development objectives. Further difficulties come near with members of the Organisation of Petroleum Exporting Countries (OPEC) also being G77/China constituents. Short-term economic motivations of such countries would deter them from cutting greenhouse gas emissions, under the justification of common but differentiated responsibilities. Continuing emissions from these large developing countries directly threatens the viability of SIDS and compromises their power in inflicting necessary change among high emitting developed nations. This part between developing count ry negotiating partners therefore must be overcome, to protect the existence of Small Island Developing States.CONCLUSIONThe effects of Climate Change continue to augment with historic greenhouse emissions presenting now unavoidable consequences and action to mitigate excessive global emissions proving inadequate. In comparison to developed and other developing nations, the 51 Small Island Developing States contribute minimally to global greenhouse emissions, yet incongruously it is these nations that are projected to experience the greatest adversity from resulting changes in climate. These countries already endure water and food security and human health issues, with characteristics such as remoteness, limited resources and small physical size and population compromising their development, especially in a sustainable sense. Hence, these countries have a low adaptive capacity with instability in climatic events only going further their socio-economic issues and in some cases, the c ontinued existence of such island states is earnestly under threat.Given their limited resources for action, Small Island Developing States require assistance from the international community in terms of both Climate change relief and adaption. With their low emission, SIDS have low mitigation potential. Hence, high greenhouse gas emitters must take responsibility to improve their environmentally hazardous practices for the global good. Financial and technical support can also be provided by developed countries to enhance the adaptive capacity and overall resilience of SIDS. Existing funding programs and frameworks should be extended and a specific fund for SIDS established (similar to the LDS fund), to achieve the necessary but exorbitant costs of adaptation. Most importantly however, international intervention must be contextually sensitive and employ local involvement and knowledge to ensure legitimate capacity building, resilience and self-sufficiency of Small Island Developin g States.
