Introduction:
Vulnerability is a condition of well-being and is not the same for different populations living under different environmental conditions or faced with complex interactions of social norms, political institutions and resource endowments, technologies and inequalities. In any case, the most generally utilized definition is given by IPCC (2001), which characterizes vulnerability as “the degree to which a system is susceptible to, or unable to cope with, adverse effects of climate change, including climate variability and extremes.” In this line, vulnerability is comprehended as a component of: V¼f (E, S, AC), where E¼exposure (the character, size, and rate of environmental change, and the variety to which a framework is uncovered), S¼sensitivity (basic factors that either elevate or decrease the effect of introduction, for example, arrive residency), and AC¼adaptive limit (the capacity of a framework to conform to environmental change, including atmosphere fluctuation and boundaries, to direct potential harms, to exploit openings, or to adapt to the outcomes). As atmosphere is changing and weakness is expanding. Here major powerless networks and their degree of powerlessness are examined.

Regional vulnerable people:
In Asia, The quantity of seaside inhabitants in Asia adds up to 1.7 billion individuals, the likeness the greater part of the area’s populace. The principle effects of environmental change on waterfront zones of Asia will comprise of ocean level ascent and more regular and serious tempest occasions. Bangladesh and India are especially defenseless against tropical violent winds and tempest floods: around 76% of the aggregate loss of human lives from cyclonic tempests has happened in India and Bangladesh. Southeast Asia has right around 33% of the world’s mapped coral reefs, a significant number of which are as of now experiencing fast natural surroundings demolition. In Africa, countless in Africa are helpless against ascends in ocean level because of environmental change, as more than one-fourth of the number of inhabitants in Africa dwells inside 100 km of an ocean drift. It was assessed that upwards of 70 million individuals could be influenced by flooding in 50-60 years in view of beach front disintegration and ocean level ascent. In Latin America, Sea-level ascent in Latin America could be more prominent than the evaluated worldwide normal. Roughly 1600 km of coral reefs and 870km of mangroves are situated in the area of Central America. Effects of environmental change on these delicate biological systems could put in danger a huge number of animal categories and assets for rustic networks living in seaside territories. Seaside zones with economies that depend on angling and tourism will be most influenced via ocean level ascent. In Australia and New Zealand, Water shortage is relied upon to increment in southern and eastern Australia and in addition in the northern and eastern parts of New Zealand. Moreover, as a result of anticipated dry seasons and flames horticultural profitability and ranger service is relied upon to decrease. In Europe, Southern Europe and Central and Eastern Europe are relied upon to confront expanding water pressure and in Southern Europe the probability and recurrence of out of control fires is required to force additionally weight on a district effectively defenseless against aridity (IPCC 2007a).

Vulnerability of Indigenous people in the Arctic:
The dangers presented by environmental change to conventional networks are likely best archived for the indigenous people groups of the Arctic. They are additionally the main indigenous networks said in the rundown of IPCC’s Fourth Assessment Report. It is perceived that the Arctic is currently encountering the absolute most fast and serious environmental change on earth (ACIA, 2004), and that progressions will proceed at a quickened pace. Movements of vegetation zones, changes in creature species assorted variety, range and dissemination, decrease of the degree and thickness of ocean ice, ocean level ascent or expanding presentation to storm are a portion of the difficulties that Arctic people group should confront.
Vulnerability of the people of Small island states:
Most of the island states are situated in the ocean. These are small land of heterogeneous group although they share some common characteristics that make them vulnerable to climate change effect. They have limited area of resources with less developed infrastructure. So their adaption capacity to climate change is very much complicated. Sea level rising, water pollution, water temperature rising and many other climatic factor has immense effect on the people of this states. For example Maldives as lowest lying land are faced with the risk of extinction due to the sea level rise and may be the first “sea-level refugees” in the world. The oceans are a major reservoir of carbon sink may store 50 times more CO2 than the atmosphere. This huge amount of CO2 may cause acidification impact on marine biodiversity and may seriously affect the coral reefs which is ultimately the source of livelihood for millions of people.
Vulnerability of Indigenous Peoples in the tropical rainforest belt:
Significant populations of ethnically distinct indigenous peoples live in the major humid forest areas of the Amazon and Congo Basins, the islands of Borneo and New Guinea, the Guyana shield and Central America and in other humid forest areas in Asia, Africa and Latin America. Environmental change makes exceptional dangers for these people groups and their interests are once in a while considered in environmental change arrangements on moderation or adjustment alternatives. Indigenous people groups of the tropical rainforest belt are exceptionally reliant on the forest. A large number of them are as of now today influenced by the effects of ecological and environmental change and are struggling to adapt to the changing environment. The majority of these people groups are hunters gatherers. (e.g. the Dayak of Borneo, the Papuans of New Guinea, Amerindians in South America, Pygmies of the Congo Basin and so forth). Traditional knowledge of indigenous groups has changed due to the climate change. At present natural signals are less reliable than the previous due to climate change which was considered as trigger of different activities to the ethnic community. As the weather is getting warmer and migratory birds come at a different period, rainy season comes earlier or later which can lead the ethnic community to disorientation of their lives.

Vulnerability of dry land people:
About 40% of the earth’s terrestrial surface covers as dryland and are home to over 2 billion people, the majority of them are poorest people in the world (MA 2005b). Most of the ‘poorest’ people living in drylands are pastoralists, hunter-gatherers and other traditional communities that can be considered as indigenous peoples according to international standards (ILO Convention No.169 Article 1). Hence, drylands and the people living in drylands appear to be one of the most affected by climate change, given the already existing water stress, land degradation and the limited capacity to adapt in these regions (IPCC 2007a; MA 2005 a3).
Vulnerability of ethnic community lives in remote or mountainous area:
Mountains, for example, are areas of high cultural as well as biological diversity but are also considered among the regions which are expected to be most affected by adverse impacts of climate change. Mountain glaciers and snow packs feeding lakes and creeks have already declined significantly especially in the northern hemisphere and permafrost has degraded, leading to changes in land surface characteristics and drainage systems. (IPCC, 2007a). Climate change is likely to further aggravate the situation of indigenous and traditional peoples, especially those living in places that are susceptible to natural disasters, and will consequently further limit their ability to cope with or recover from shocks (DFID, 2004). Many indigenous peoples live within natural ecosystems and are therefore exposed to numerous health hazards mostly as a consequence of their difficult environment.
Vulnerability of Indigenous people in Bangladesh:
Bangladesh is noted for the ethnic homogeneity of its populace, of which around 897,828 individuals are indigenous as per the statistics of 1981 (marginally over 1% of the populace) (SDNP, 2004). Bangladesh is also one of the most highly disaster-prone countries of the world (Srinivasan, 2004) and is expected to be affected severely by sea-level rise due to climate change, as it is a flat deltaic land. It was predicted that a 1.5 meter rise would affect 17 million people (about 15% of the population) and 22,000 squar kilometer of land (about 16% of total land surface) (UNEP/GRID, 2007). Coastal peoples, whose livelihoods mainly depend on resources such as fisheries and mangroves, are expected to be severely affected by the effects of climate change and natural hazards. Impacts of climate change are already being felt in the country.
Vulnerability of Indigenous peoples in Borneo, Indonesia:
Changes in atmosphere have been detected by the Dayaks as a result of different indicators. They watched bird species that they had never observed, they observed that the level of water in the rivers is higher/lower than usual for the season and that the traditional plants used as medicinal remedies are disappeared. Behavior and migration patterns of birds have traditionally been used to guide hunting and cultivation activities but they no longer provide reliable guidance.
One of the remaining hunter-gatherer communities in East Kalimantan is the Punan people. Their activities are maintained by following lunar calendar. According to the phases of the moon, they decide upon activities such as planting agricultural and tree crops, clearing cultivation areas, hunting etc. But with the changes of climate these lunar signals may no longer coincide with the favorable times for these activities and the Punan may be misled in taking their decisions (Boedhihartono, 2004).

Vulnerability of indigenous peoples of South East Cameroon and Congo:
In the forests surrounding the village of Mambele in SE Cameroon and Bomassa in N. Congo, the Baka and the Bambendzele individuals have needed to adjust their lifestyle to improvement programs, particularly industrial logging and now they need to manage the environmental condition. Rainfall has reduced and harder to predict. Women who generally catch fish in streams in dry season are often unable to catch fish due to changing flood patterns of river. In West Africa deforestation connected in any event to a limited extent to environmental change has prompted flare-ups of infections in regions where they had not before caused issues. In parts of the Upper Guinea savannas of Ghana and neighboring nations meningitis flare-ups among rural individuals have been connected to environmental change.
Vulnerability of indigenous peoples in Nicaragua:
Miskito Indians make up the majority of Nicaragua’s 85,000-in number indigenous population. They live in Nicaragua’s western regions and subsist on crops that are planted on a couple of hectares of land and food hunted from the jungle and rivers. Floods occur in the summer followed by drought in the winter, so planting season is completely out of traditional rhythms of the Miskito culture. For this reason Miskito are already being severely affected by changes in climate. Furthermore, temperatures across Central America are expected to rise by 1°C-3°C and rainfall will decrease by 25% by 2070 (Kelly, 2007). Droughts, hurricanes and unseasonal flooding are just a few of the expected consequences of such a rapidly changing climate. However, the long-term ability of the Miskitos to adapt is looking increasingly uncertain.
Vulnerability of traditional and indigenous traditional peoples in Tanzania:
Depending on the present warming trend it has projected by expart that Mount Kilimanjaro’s glaciers will be disappeared by the year 2020. This increasing temperature and decreasing precipitation will increase frequent forest fire. This continuous climate trend, frequent forest fire and human intervention will reduce the rest of the sub-alpine forest of this mountain and seriously damage it’s water catchment and also its drainage system. Due to this condition mountain based traditional community will be hampered severely (Mwangi, 2002).
Vulnerability of Traditional Anangu ethnic community of Central Australia:
Anangu community people lives in central Australia maintained patch-burning mosaic vegetation as their cultural practice for livelihood and habitation. Actually they maintained this practice for hunting which is associated with their migration across vast area of the country though it is noticed in central Australia (Haydon et al., 2000). Increasing forest fire increases the risk of the community and changing the vegetation pattern. At the time of last very wet season in 1973-74, which was associated with La Nina effect strong vegetation was found throughout the central Australia that ultimately increased the fuel load, and McArthur and Luke (1978) describe the subsequent serious fire than after average rainfall years. So, fire management issue were the most challenging issue for Anangu ethnic community. At present climate fluctuation is influencing the fire and invasive species management. During la Nina years due to heavy rainfall invasive species grow in higher rate over the native important species that increases the fuel load and increases the frequent susceptibility of catching fire during hotter months because many species become less adapted during the establishment of vegetation (Bardsley and Edwards-Jones, 2007; Kriticos et al., 2010). So, climate change to both very wet and dry period will increase the fire risk of invasive species which need to be managed and this trend will hamper the socio-ecological condition of Anangu ethnic community and will make them more vulnerable to climate change than the previous.

Vulnerability of Indigenous and traditional peoples in Lima:
In Lima the most burdened and poorest individuals from the Peruvian population were compelled to possess the most exceedingly awful domains of the city which are vulnerable to immersions, disintegration and mudslides. An ongoing report by the Metropolitan Institute for Planning of the city of Lima has discovered that there is a reasonable connection between the social status of people and their exposure to risk (Villacorta et al., 2005). The building techniques and quality of housing are linked to the location of residence, the availability of local resources and the local culture. The way houses are built is often based on traditional knowledge. As access to non-local building materials is regularly limited because of logistical or economical constraints, houses are usually built out of locally available materials such as adobe, timber, bamboo, fiber, leaves or tree bark. Such houses are usually well adapted to local conditions, but may be less resistant to new hazards than houses built purposefully with more resistant materials, and may not endure the force of expected future hazards.

Vulnerability of miscellaneous indigenous peoples:
Indigenous peoples are among the first to face the direct consequences of climate change, owing to their dependence upon, and close relationship with the environment and its resources. Here some other indigenous peoples vulnerability are discussed-
? In Himalayas high altitude, glacial melts affecting hundreds of millions of rural dwellers who depend on the seasonal flow of water is resulting in more water in the short term, but less in the long run as glaciers and snow cover shrink.
? In the Amazon, the effects of climate change include deforestation and forest fragmentation, and forest fire consequently changes the Amazon region replacing with savanna that ultimately affect the livelihoods in this region.
? Reindeer is very much vital as food and cultural source to Saami communities In Finland, Norway and Sweden. But due to climate change rain and mild weather during the winter season often prevents reindeer from accessing to them that caused massive loss of reindeer
? In Africa’s Kalahari Basin vegetation is negatively affected by Rising temperatures, dune expansion, increased wind speeds, and loss of vegetation which hamper traditional cattle and goat farming practices by indigenous peoples.
Conclusion:
Even though it is not possible to make accurate projections for future global change in local places or for specific groups with the data currently available, it is nevertheless possible to locate broad regions which are likely to experience certain types of environmental change. The areas of high risk with regard to changes in precipitation and surface temperature include: the Arctic region, the Caribbean and the Mediterranean region, the very south of Latin America and the Amazon, southern Africa, the Arabian Peninsula and large parts of Australia. So, indigenous people living in this region will be affected severely due to climate change effect.
