Vulnerability is a function of the character, magnitude, and rate of climate variation to which a system is exposed, its sensitivity, and its adaptive capacity IPCC 2001 De Stefano et al 2015 Vulnerability of a system is determined by an external dimension, defined by the characteristics of the hazard, and an internal dimension that comprises its sensitivity or the conditions of the system that reduce or exacerbate impacts, and its capacities to mitigate, respond or adapt to those impacts Vulnerability refers to the characteristics of a group in terms of its capacity to anticipate, Iglesias et al 2007/2009 cope with, resist and recover from the impact of drought. Vulnerability to drought refers to the degree of exposure to water deficit. Areas that have Jain et al 2015 higher exposure and low coping capabilities would have the highest risk from a given drought event and vice versa Vulnerability to agricultural drought means that the extent of agriculture potential sensibility Jiang et al 2012 to the drought threat (Liu et al 2002) The conditions determined by physical, social, economic and environmental factors or Jordaan 2012 processes, which increase the susceptibility of a community to the impact of hazards (UNISDR, 2004). Vulnerability is a dynamic systemic attribute that fluctuates in time following the various Karavitis et al. 2011 changes that occur in the system of interest (Adger and Kelly, 1999; Dalziell and McManus, 2004; Leichenco and O’Brien, 2002; Luers, 2005; Miller et.al, 2010). Vulnerability is conceptualized to describe the degree to which a socio-economic system or Kim et al. 2013 physical assets are either susceptible or resilient to the impact of natural hazards (Wilhelmi and Wilhite, 2002). Condition resulting from social, economic, and environmental factors or processes, which Kipterer and Mundia increases susceptibility of agricultural systems to the impact of drought hazard (CWCB 2014 2010) Vulnerability refers to the frangible nature of a system faced with various types of potential Liu et al 2013 disasters Vulnerability refers to the potential for loss (Cutter 1993). Etkin et al. (2004) defines vulnerability as the propensity to suffer some degree of loss from a hazardous event, Long et al 2011 whereas Turner et al. (2003) defines it as the degree to which a system is likely to experience harm due to exposure to a hazard Agricultural drought vulnerability is a measure of the capacity of the agricultural area of an Murthy et al 2015 administrative unit to cope up with the drought situation. Vulnerability refers to the characteristics of a group in terms of its capacity to anticipate, Naumann et al 2014 cope with, resist and recover from the impact of drought. Vulnerability refers to the degree of susceptibility to a hazard either as the result of varying Pandey et al 2010 exposure to the hazard or because of variation in the ability to cope with its impact References Vulnerability definition Pereira et al 2014/ Vulnerability can be defined as the susceptibility of human systems to natural phenomena, Pereira et al 2011 and is frequently associated with specific losses or damages (Morton 2007). Social vulnerability to drought is complex and reflected by society’s capacity to anticipate, Safavi et al 2014 cope with and respond (Tsakiris and Pangalou 2009) Shahid and Behrawan Describes the degree to which a socio-economic system or physical assets are either 2008 susceptible or resilient to the impact of natural hazards (Wilhelmi and Wilhite 2002) Shiau and Hsiao 2012 Drought vulnerability measures lack of resistance to droughts Vulnerability’’ refers to the extent to which a drought of a given size (measured Simelton et al 2009 meteorologically) has an impact on agricultural production (measured in terms of harvest). Vulnerability of an agricultural system to diverse weather can be observed when relatively small weather anomalies have disproportionately large impacts on crop production. One reason for this may be that underlying socio-economic factors could have inhibited Simelton et al 2012 adaptation. Such vulnerable cases may be contrasted with situations where large weather anomalies seem to have caused little production loss. In these cases, fraser et al. (2011) hypothesize that underlying socioeconomic factors may have enhanced adaptive strategies (fraser 2007 and fraser et al 2011) The susceptibility of a system to disturbances determined by exposure to perturbations, Sookhtanlo et al 2013 sensitivity to perturbations, and the capacity to adapt (Nelson 2007) Set of conditions and /Khoshnodifar et al 2012 processes resulting from physical, social and economic factors, which increase the susceptibility of a community to the impact of hazards (ISDR 2004) Swain and Swain 2011 The composite of conditions and exposure to adverse processes that increase the (2 paper) susceptibility level of populations and their habitations to drought (UNEP 2001) The degree of susceptibility of society to a hazard, which could vary either as a result of Wilhelmi and Wilhite variable exposure to the hazard, or because of coping abilities Own definition based on 2002 others The property that the structure and function of a system (including subsystems and system Wu (Di) et al 2013 components) is prone to damage, due to its sensitivity to internal and external disturbances, as well as its lack of coping capacity respond to such circumstances (Li et al. 2008) Vulnerability is composed of exposure, sensitivity and adaptive capacity (IPCC 2007; Polsky Yuan et al 2013 et al. 2007, Pandey and Jha 2012; Liu et al. 2013) The characteristics of a person or group in terms of their capacity to anticipate, resist, cope with, and recover from the impact of natural or man-made hazards (Blaikie et al., 1994; Zarafshani et al 2012 IFRC, 1999; Ethlet and Yates, 2005; Paavola, 2008). According to IPCC (2001), vulnerability is defined as the extent to which a natural or social system is susceptible to sustaining damage from climate change Vulnerability to a natural hazard is the degree of loss as a result of potential hazard in a Zhang et al 2014 given region (UN 1991), the potential maximum loss of life and property due to drought hazards in a given region during a given time period.
