Getting the scale right: a comparison of analytical methods for vulnerability assessment and household-level targeting

Evaluating dual exposure by using climate-conflict vulnerability index on the coastal districts of Sindh, Pakistan

Climate variability is widely recognized as a major concern, particularly in resource-scarce regions where it limits livelihood opportunities by putting additional strain on already depleting resources, resulting in human insecurity and conflicts. Some vulnerability assessments have created a nexus between climate variability and conflicts. The Climate-Water Conflict Vulnerability Index (CWCVI) and the Climate-Agriculture Conflict Vulnerability Index (CACVI) are applied as a tool for exploring the climate and conflict interactions, as well as contrasting the vulnerabilities of the coastal districts of Badin, Thatta, and Sujawal. The analysis incorporates a dual exposure of communities in the form of climate variability and conflict over water and agricultural resources. The study finds that aggression and feelings of insecurity about depleting resources are the main contributing indicators of climate-conflict vulnerability in the coastal districts. District Sujawal showed higher vulnerability in adaptive capacity as compared to the other districts due to poor infrastructure and high dependency on natural resources. However, the district of Badin demonstrated high vulnerability in terms of sensitivity and its exposure to conflicts over agricultural resources is high. The overall CWCVI and CACVI scores were higher in Badin and Thatta, respectively. This study identifies a number of indicators that can be used to improve the efficacy of mitigation strategies to reduce conflict vulnerability in future policy directions and resource planning.

Indicator-based approach for assessing the vulnerability of freshwater resources in the Bagmati River basin, Nepal

To assess the vulnerability of water resources in the Bagmati River Basin in Nepal, this paper adopts an indicator-based approach wherein vulnerability is expressed as a function of water stress and adaptive capacity. Water stress encompasses indicators of water resources variation, scarcity, and exploitation and water pollution, whereas adaptive capacity covers indicators of natural, physical, human resource, and economic capacities. Based on the evaluation of eleven indicators, which were aggregated into eight vulnerability parameters, an increasingly stressful situation and lack of adaptive capacity became evident. Considerable spatial variation in indicator values suggests differential policy options. While the northern parts need attention to reduce pollution loading and conserve vegetation cover, the southern parts need improvements in physical capacity, i.e. water infrastructures. The comprehensive and easily interpretable findings of the study are expected to help decision makers reach sound solutions to reduce freshwater resources vulnerability in the Bagmati River Basin, Nepal. With its inherent flexibility, the approach has demonstrated its potential for application in different times and areas for monitoring and comparison purposes.

Measuring populations' vulnerabilities for famine and food security interventions: the case of Ethiopia's Chronic Vulnerability Index

The concept of vulnerability has become an important part of food security analyses since the 1980s. It is seen as having two sides: exposure to external hazards; and an inability to cope with those shocks, attributed to social, political, and economic factors. Numerous attempts have been made to construct models to determine levels of vulnerability among populations. This paper analyses one such attempt, the Chronic Vulnerability Index (CVI), developed to measure levels of vulnerability to food insecurity in Ethiopia. The example of the CVI reveals many of the difficulties associated with producing a basic model of vulnerability that can be used in disaster mitigation. Ultimately, the CVI assumes that vulnerability is a linear, additive phenomenon with discrete causes and effects and fails to capture interactions between hazards and the human systems that produce and complicate them. The paper concludes with a discussion of alternatives to the CVI.

The underutilization of street markets as a source of food security indicators in famine early warning systems: a case study of Ethiopia

Famine Early Warning Systems (EWS) are reliant on data aggregated from multiple sources. Consequently, they are often insensitive to localized changes in food security status, leading to delayed response or interventions. While price and infrastructural data are often gathered, this case study suggests that local street markets and vendor knowledge are underutilized. Few efforts have been made to monitor systematically the street markets as an indicator of local stressors. Findings from Ethiopia show that knowledge generated by expanding food security indicators in this sector can be used in combination with EWS to facilitate earlier intervention in, or to monitor more effectively, on-going humanitarian crises. Indicators developed from this study are accurate, cost effective, and sensitive to local climatic and food stressors.

Reducing hazard vulnerability: towards a common approach between disaster risk reduction and climate adaptation

Over the past few decades, four distinct and largely independent research and policy communities--disaster risk reduction, climate change adaptation, environmental management and poverty reduction--have been actively engaged in reducing socio-economic vulnerability to natural hazards. However, despite the significant efforts of these communities, the vulnerability of many individuals and communities to natural hazards continues to increase considerably. In particular, it is hydro-meteorological hazards that affect an increasing number of people and cause increasingly large economic losses. Arising from the realisation that these four communities have been largely working in isolation and enjoyed only limited success in reducing vulnerability, there is an emerging perceived need to strengthen significantly collaboration and to facilitate learning and information exchange between them. This article examines key communalities and differences between the climate change adaptation and disaster risk reduction communities, and proposes three exercises that would help to structure a multi-community dialogue and learning process.
