This study examined the vulnerability of smallholder maize farming households to climate change in the Brong-Ahafo region of Ghana by employing the Livelihood Vulnerability Index with particular emphasis on access to and utilization of water resources. Livelihood Vulnerability index was developed which includes social vulnerability, infrastructure development, biophysical conditions, climate, agriculture and livestock, and transportation (Fig 1). This ranking allows those Climate and Development: Vol. Water Science and Technology, Special Issue on Climate Change Vol 51 No 5 pp 69–78, 30, 1195-1210. The Multidimensional Livelihood Vulnerability Index – an instrument to measure livelihood vulnerability to change in the Hindu Kush Himalayas. Livelihood vulnerability index analysis: An approach to study vulnerability in the context of Bihar “livelihood coping” given higher levels of vulnerability and more severe shocks (Maxwell et al., 2003). Peer review under responsibility of Kasetsart University. The Climate Vulnerability Index (CVI) and an illustration of its application to Mongolia Caroline A Sullivan 12 and Erdenemunkh Byambaa 1 Water is the primary medium through which climate change influences Earth’s ecosystem and thus the livelihood and well-being of societies ” (WWAP, 2012).

Social vulnerability refers to the potential negative effects on communities caused by external stresses on human health. These results have implications for the initiation and implementation of climate change adaptation and household resilience projects by the government, donor agencies, and other related organizations in the two municipalities in the region. 3. 1.1 Levels of Analysis Vulnerability assessment methodology is determined by the overarching conceptual framework chosen, including a definition of vulnerability that specifies risks for … In this study, the LVI is scaled from 0 (least vulnerable) to 0.5 (most vulnerable). Once compiled then this data must be used to calculate each indicator. index, sectorial vulnerability indices can be segregated to identify potential areas for intervention (Hahn et al. The Livelihood Vulnerability Index: A pragmatic approach to assessing risks from climate variability and change—A case study in Mozambique. where LVI b is the livelihood vulnerability index for the block b, and the weightage of the eight major components, W Mi, determined by the number of subcomponents that make up each major component, contribute equally to the overall LVI (Hahn et al. The index will shed new light on the different degrees and levels of household vulnerability introduced by the HIV and AIDS pandemic on household agriculture and food security. the Multidimensional Livelihood Vulnerability Index (MLVI), using primary data gathered by the application of the VACA survey. Furthermore, farming households in Wenchi municipality were more vulnerable in terms of adaptive capacity, taking into account the socio-demographic aspects, social networks, and livelihoods of households in the municipality than those in Techiman municipality. The EVI is accumulated into three sub-indices: We surveyed 200 households in each district to collect data on socio-demographics, livelihoods, social networks, health, food and water security, natural disasters and climate variability. This pragmatic approach may be used to monitor vulnerability, program resources for assistance, and/or evaluate potential program/policy effectiveness in data-scarce regions by introducing scenarios into the LVI model for baseline comparison. For example, SDP has four sub-components, so W SDP According toIPPC (2007), the vulnerability assessment measures the ability of the community to respond to hazard and or secure their livelihood. 9, … The chapter first presents the concepts of livelihoods, poverty, and inequality, and their relationships to each other and to climate change. Results suggest that Moma may be more vulnerable in terms of water resources while Mabote may be more vulnerable in terms of socio-demographic structure. Through such an index "diverse issues can be combined into a standardised framework...making comparisons possible". Data were aggregated using a composite index and differential vulnerabilities were compared. By continuing you agree to the use of cookies.

Phu1 and N. N. De2 Abstract This study, conducted in An Giang Province of Vietnam, assesses the vulnerability and adaptability of local farmers to the flood in different conditions. Index ranges between 0 and 2. eCalculated as sum of household scores (no =0, yes 1), based on the 3 variables: livestock, jewellery and stored food. Assessing Vulnerability to Climate Change: The Livelihood Vulnerability Index (LVI) In modeling the vulnerability to climate change by smallholder maize farming households, the balance weighted approach was employed by computing the LVI as developed by Hahn et al. This study adopted the SLF (Sustainable Livelihood Framework) [4] to guide the assessment of livelihood vulnerability to SI. The LAT consists of three main technical elements: Livelihood Baseline Assessment (which is undertaken pre-disaster); Immediate Livelihood Impact Appraisal (undertaken immediately after the disaster); and Detailed Livelihood Assessment (undertaken up to 90 days after the disaster). (2013). vulnerability due natural disasters and variability which is one of the components indicators used to calculate farmer’s livelihood vulnerability index (LVI). developed the Livelihood Assessment Tool-kit (LAT). z is the Livelihood Vulnerability Index for zone z and equals the weighted average of the seven major components pertaining to that zone z. W mi, or weights of each of the major components are determined by the number of sub-components that make up each major component. The Livelihood Vulnerability Index (LVI) approach is a practical tool for assessing how vulnerable the sector is and which livelihood component contributes to its vulnerability. We surveyed 200 households in each district to collect data on socio-demographics, livelihoods, social networks, health, food and water security, natural disasters and climate variability. an external stress.

Abstract We developed the Livelihood Vulnerability Index (LVI) to estimate climate change vulnerability in the Mabote and Moma Districts of Mozambique. These strategies include liquidating productive assets, breaking social obligations, withdrawing children from school to … This livelihood lens also reveals how inequalities perpetuate poverty to shape differential vulnerabilities and in turn the differentiated impacts of climate change on individuals and societies. Such stresses include natural or human-caused disasters, or disease outbreaks. Livelihood vulnerability index approach Vulnerability is one of the factors that determines whether people have risks to their livelihoods or not. Different documents regarding adaptation policies and sectoral vulnerability assessment was also collected. We developed the Livelihood Vulnerability Index (LVI) to estimate climate change vulnerability in the Mabote and Moma Districts of Mozambique. Livelihood Vulnerability Index (LVI) proposed by Hahn, Riederer, and Foster (2009, Global Environmental Change, 19(1), 74–88) was applied for livelihood vulnerability analysis of different flooding zones (upper, middle and lower zones) in low flooding condition. Livelihood coping strategies can have longer-term negative effects on a household. 2009; Sullivan 2002). Both indexes validly reflect the relative difference in terms to examining the vulnerability index of climate change and both could usefully form the basis for a nationally applicable The livelihood challenges facing returnee households are mainly lack of enough livelihood activities, poor soils and related low yields, reintegration process which is still incomplete for some, incapacity to compete on labor market, and lack of land to cultivate. CDC Social Vulnerability Index. The MLVI is designed to measure multi-dimensional livelihood vulnerability to climatic, environ-mental, and socio-economic change in a region that is Sullivan, C.A. These were combined into vulnerability indices and mapped as vulnerability … https://doi.org/10.1016/j.gloenvcha.2008.11.002. To calculate the LVI for study sites, a balanced weighted average approach was used where each subcomponent contributed equally to the overall index. We surveyed 200 households in each district to collect data on socio-demographics, livelihoods, social networks, health, food and water security, natural disasters and climate variability. Reducing social vulnerability can decrease both human suffering and economic loss. The primary data were based on 150 maize farming households, complemented by secondary data on rainfall and temperature over the period 1983–2013. E.g. Method and Materials When constructing the livelihood Vulnerability index to assess the impacts of MGNREGS on asset creation in the study area, the following background studies are carefully reviewed. poverty.
