livelihood vulnerability index calculation

Mitig Adapt Strat Global Chang 4:267–281. This study aims to examine the willingness of Pakistani farmers to pay for insurance premiums by conducting a household survey. However, the present study concluded that for delineating the vulnerability state of any area, hybrid ensemble model can be a better option over others. This research provides an important starting point for directing future research into the vulnerability of fishery-based livelihood systems to climate variability and change. Sensitivity to climate variability and change is influenced by conditions at the community and household level. Adaptive capacity of households is limited because of the lack of physical, natural, and financial capital and limited diversification of livelihoods. Financial capital, particularly income, is also an important indicator of adaptive capacity. The communities across watersheds showed a relative difference in the overall livelihood vulnerability index. • Health/Nutrition Profiles and other Livelihood Outcomes (Health and diseases, access to water and sanitation, consumption patterns, dietary diversity and nutritional status) • Shocks and Vulnerability Information (History of natural disasters, historical shocks International Journal on Advanced Science Engineering and Information Technology. Results obtained from the survey conducted in 2018 and 2019 explore the co-existence of climate change vulnerability and resilience at the rural household level. this study made it possible to make a comparative analysis of the deprivations suffered by Depleting water resources alarms us our approach toward development and drives us to take sustainable approach to conserve our natural resources. p 50, Vietnam: Focus on the relationship between tectonic fractures and landslides. 2003; IPCC 2007). The result shows that, each of these metrics varied systematically where the lowland agro ecological zone is the most exposed zone, the highland is the most sensitive zone and the midland is the most in adaptive capacity to climate variability and change. Through such an index "diverse issues can be combined into a standardised framework...making comparisons possible". Where V, E, S and AC represent vulnerability, exposure, sensitivity and adaptive capacity of a household, respectively. While a number of studies have investigated the impact of climate change on the vulnerability and adaptive capacity of the fisheries sector at the national scale (e.g. Livelihood vulnerability index results. A composite index approach computes vulnerability indices by aggregating data for a set of indicators. market and house and climate change experience influence adaptationmeasure choices. The dataset from the sampled households was divided into quartiles of vulnerability (very high, high, moderate, and low), each representing a fourth of the population sampled for each indicator and index (Table 3). Application of livelihood vulnerability index to assess risks, ood vulnerability and climate variability, a case study in the Mekong delta of Vietnam. strategies and social networks; exposure to climate change and climate-induced extreme weather events, such as floods and droughts; and access to services and infrastructure. 38 Asia-Pacific Journal of Rural Development 29(1) Introduction An Giang is a province in the Mekong downstream area frequently affected by annual flood. At the local level, exposure and sensitivity are almost inseparable, and it is challenging to characterise them (Smit and Wandel 2006). doi:10.1111/j.1477-8947.2010.01302.x, Haddad BM (2005) Ranking the adaptive capacity of nations to climate change when socio-political goals are explicit. The normalised adaptive capacity sub-index was inverted (1- index) for inclusion in the vulnerability index because the potential impact (which is a function of exposure and sensitivity) of climate variability and change may be offset, reduced or modified by adaptive capacity (IPCC 2007). Among the 26 parameters , bank erosion, unhygienic condition, and Below Poverty Level (BPL) household parameters were found as highly dominating based on the findings of information and gain ratio. nancial, physical, and social capitals. Both could be usefully utilized into identification and prioritization of adaptation and mitigation policies at universal level. 54209. All three indicators of sensitivity are significant (p < 0.001 for most indicators) in distinguishing vulnerability classes in both communities. p 48. These components include competency, education, financial condition, livelihood strategy, social networks, socio-demographic profile, housing, water, energy, health, financial status, communication, climate extreme impact, geographic location, risk index and warning system. The qualitative data were transcribed in Bengali and analysed using coding techniques (Miles and Huberman 1994) before translation.

These factors are interrelated. Shannon’s entropy is one of the methods for assisting in making decision (ranking) objectively. 3.5 Livelihood vulnerability index calculation 3.5.1 Calculating the LVI: composit e index approach All eight major components of the LVI com prise several indicators or sub-components, and For instance, effective governance is important for adaptive capacity (Paavola 2008), but it is difficult to capture in an indicator (Vincent 2007). According to almost all the participants, floods are the most important determinant of vulnerability inland, while at sea it is cyclones. Proposed model accounted that about 36% to the total study area is under high to very high LVS and this area mainly covers the peripheral part of the charland. In Benin, agriculture fuels economic growth, offers investment opportunities and provides raw materials for the industry. Other impacts include physical injuries (Badjeck et al. ILRI (International Livestock Research Institute). 2009). ing the standardized scores of each main component: where M is one of the 13 major components, major component. doi:10.1007/s10113-010-0164-y, Smit B, Wandel J (2006) Adaptation, adaptive capacity and vulnerability. After normalisation the respective values were averaged to yield the three sub-indices for exposure, sensitivity, and adaptive capacity. Besides, local government should propagandize and mobilize farmers here to give up backward, Infrastructural factors affecting vulnerability to climate-induced health shocks were not, study area, access to safe water was nonexistent in Pa Vay Su and limited in Hien Luong, (9.1%) and Moc Chau (27.3%), although a clean water program has been widely imple-, mented in the rural areas in the northwestern provinces during 2001, Main water sources for crops and livestock are natural resources. Area under curve (AUC) in Receiver operating characteristics (RoC) reported that the accuracy level is 0.96 in case of proposed model over maximum 0.92 predicted by the others. The DPSIR framework helps in identifying the indicators of LVI and LEI vulnerability index as cause-effect relationship. nal sample size was 335 with completed questionnaires. measured by the number of natural disasters that have occurred in the past 6 years, while climate variability is measured by the average standard deviation of the maximum. 2007). was conducted to determine the level of livelihood vulnerability using sixteen components that measures adaptive capacity, sensitivity and exposure.

This enabled us to gain insights into the determinants of livelihood vulnerability among similarly exposed households (Eakin and Bojórquez-Tapia 2008). River island (locally charland) of Ganges river from Rajmahal hill to Farakka barrage in India is the human occupancy of the river bank erosion evicted people, but these areas are under different vulnerabilities like bank erosion, flooding, poor livelihood etc. All rights reserved. The DPSIR framework also provides the feedback of cause-effect continuous process which will be helpful in developing the capacities to cope or adapt to the vulnerability as responses factor. the effect of an infinitesimal change of temperature and rainfall in Northwest farming, marginal A field survey was conducted to assess the Livelihood Vulnerability Index (LVI), comprising major and sub-components of vulnerability for ten sub-districts in Pekan. A range of indicators such as the number of adult workforce, quality of house, number of fishery materials, natural capital, financial capital excluding income, per capita income, social capital, and number of income-generating activities are significant (p < 0.001–p < 0.05) in distinguishing vulnerability classes of households in both communities. livelihood strategies employed, and the stren, measured by assessing the current state of a commune, The major components are combined into the LVI, tributing factor. So, these. Climate change 2001: Impacts, adaptation, . Different documents regarding adaptation policies and sectoral vulnerability assessment was also collected. Extreme weather events such as cyclones and floods may further intensify these impacts by disrupting fishing operations and land-based infrastructure (Westlund et al. In the coming decades, the vulnerability of fishery-based livelihoods may substantially increase because of climate change. Purpose Consequently, there is limited knowledge available on the adoption of crop insurance in Pakistan. There is room for refining indicator-based approaches to vulnerability assessment as better indicators, models, and data become available. Typically, the index is a composite of multiple quantitative indicators that via some formula, delivers a single numerical result. The correlation with LVS and three individual models (exposure, adaptive capacity, and sensitivity) exhibited that the Exposure model was highly correlated (r = 0.87) with high statistical significance (0.001 level). LIVELIHOODS VULNERABILITY INDEX (LVI) Each of the seven major components of LVI comprises of several indicators or sub-components as shown in Table I. This increases the vulnerability of natural resources and sensitivity to, the climate change of Pa Vay Su and Hien Luong communities. Assessment of Natural disasters in Vietnam, . There is no hospital or clinic but 2 pharmacies dispense medicines. Nepal, where the majority of people are in a mixed agro-livestock system, is identified as the world’s fourth most vulnerable, The mixed crop–livestock system is a primary source of livelihood in developing countries. Descriptive statistic was used for the livelihood vulnerability index’s (LVI) and the LVI-Intergovernmental Panel on Climate Change’s (IPCC) index calculation. . Livelihood strategies with LVI value (0.49) and climate variability (0.48) were seen as the most vulnerable and health (0.12) as the least vulnerable component in the study area. Global Environ Chang 17:218–227. In a small-scale fishing community, households are involved in fishery-related activities such as fishing, post-harvest fish processing, fish trading, and making and mending of fishing materials (OECD 2001). Our results highlight that the highest livelihood vulnerability to climate variability and change does not coincide with highest sensitivity and lowest adaptive capacity. 2). These conclusions offer directions for community and national planners and policy makers in Trinidad and in other similar country circumstances where climate change is significant. However, upon closer, inspection, the analysis reveals a number of subtle, yet important, differences between these. The objective of this study was to assess the vulnerability of fishery-based livelihoods to the impacts of climate variability and change in two coastal fishing communities and their households in Bangladesh. By employing the livelihood vulnerability index (LVI), the Intergovernmental Panel on Climate Change LVI (LVIIPCC), and the livelihood effect index (LEI), this study evaluated livelihood, The purpose of the study is to develop a new Livelihood Vulnerability Index (LVI) model, which can assess and compare the vulnerability of farming communities to different extreme climate events. The findings of this study are expected to guide government, insurance companies, and policymakers in implementing crop insurance. Caroni on the other hand was more vulnerable in relation to other LVI indicators with the exception of food security. Research limitations/implications River island (locally known as charland) in river Ganges from Rajmahal hill to Farakka barrage of India is now under human habitat dominated by the environmentally evicted people triggered by bank erosion, but these are under different physical vulnerability like bank erosion, flooding etc. However, there is limited knowledge on how vulnerable mixed agro-livestock smallholders are and how their vulnerability differs across different ecological regions in Nepal.

The notion of vulnerability has become a potent diagnostic instrument for recounting conditions of susceptibility to damage, helplessness, and physical and social marginality, and for directing normative assessment of deeds to augment well-being through the diminution of risk (Adger, 2006). The range of LVI lies from 0 (least vulnerable) to 1 (high, The results of LVI values of all 13 major components calculated from 54 subcomponents of, Pa Vay Su, Hien Luong, and Moc Chau commune are presented collectively in a spider dia-, With scale in 0.1 unit increments, from 0 (less vulnerable) at the center of the web to 0.9, (most vulnerable) at the outside edge. 2011). VI-IPCC highlights three major components—exposure, adaptive capacity, and sensitivity. Therefore, the govern-, ment should continue to accelerate the new rural program, combining propaganda and. Nonetheless, based on the findings of this research, it can be tentatively said that efforts to reduce livelihood vulnerability in coastal fishing communities should be multifaceted so as to simultaneously tackle exposure, sensitivity, and adaptive capacity.

Introduction Flood occurs when water runs over its natural confines and inundates a large area of land (Lefever, Bluemle & Waldkirch 1999). Further work is needed in order to move towards an improved characterisation of vulnerability and to identify most suitable means for households and communities to cope with and adapt to the impacts of climate change. This study applied the livelihood vulnerability index (LVI) to estimate flood vulnerability of Phu Huu and Ta Danh villages in An Giang province. These impacts have already extended to fishery-dependent people in some regions (Perry et al. doi:10.1023/a:1009611621048, IPCC (2001) Climate change 2001: impacts, adaptation and vulnerability: Contribution of working group II to the third assessment report of the Intergovernmental Panel on Climate Change.

Design/methodology/approach – A logit model was used to explore farmers’ awareness and a binary The two communities have experienced similar variations in maximum temperature (Table 1) so no indicator on it was included in index calculation. The higher sensitivity of livelihoods in Kutubdia Para is due to their high dependence on climate-sensitive fisheries activities for employment, income, and nutrition (Table 4). Also, future vulnerability will be shaped not only by climate change but also by adopted development pathways (IPCC 2007). 2011). A few households depend on tailoring, grocery sales, and daily labouring in building construction for their livelihoods. The normalization method As the vulnerability of an agricultural livelihood system is different from that of fishery-based one, implications for vulnerability of one livelihood system to another is not necessarily transferable; more work is required in fishery-based systems. Implications for Climate, .

Understanding how these components and indicators influence the vulnerability of livelihoods provides an important starting point for directing future research and climate change coping and adaptation initiatives in developing countries, particularly those with fishery systems that are similar to those of Bangladesh. Population is only, The economy depends heavily on agriculture with low economic ef, the highest number of poor HHs in the country. This study examines the livelihood vulnerability of a variety of rural households by calculating the livelihood vulnerability index (LVI) with reference to the IPCC vulnerability framework and the sustainable livelihoods framework (SLF). Sensitivity of livelihoods to climate variability and change is determined by dependency on marine fisheries for livelihood because of unavailability of alternative livelihoods, lack of financial capital to invest in alternative livelihoods, lack of institutional support for livelihood diversification, and lack of human capital to engage in alternative livelihood strategies. World J Sci Technol Sustain Dev 13(4):250, Vietnam.

Dependency of indigenous communities over natural resources, like forest resources make more vulnerable in climate change. But within a fishing community, where households are similarly exposed, higher sensitivity and lower adaptive capacity combine to create higher vulnerability (for similar results in agricultural communities, see (Eakin and Bojórquez-Tapia 2008). p 131, reports number 6. 2009). A strong cyclone in the sea in 2005 and a flood caused by cyclone Aila in 2009 also had disastrous impacts on the community. Variation in past minimum temperature has not found to pose any considerable negative impacts on livelihoods in either community. Needs assessment on sustainable livelihoods that can, .
