How c.n Prac.itioners Support c.tizen Volunteers in disaster Risk Reduc.ion? Insight from “Good and Ready” in Aotearoa New Zealand

引用

International Journal of disaster Risk Sc.enc. 2024年第3期15卷 374-387页

作者： Lo?c.Le dé Steve Ronoh Ei Mon Thinn Kyu Brigitte Rive Sc.ool of Public.Health and Interdisc.plinary Studies Auckland University of Technology Pac.fic.Health Researc. c.ntre Auckland University of Technology New Zealand Red c.oss

Global and national polic. frameworks emphasize the importanc. of people's partic.pation and volunteers' role in disaster risk reduc.ion. While researc. has extensively foc.sed on volunteers in disaster response and rec.very, less attention has been paid on how organizations involved in disaster risk management c.n support volunteers in lead.ng and c.ordinating c.mmunitybased disaster risk reduc.ion. In 2019, the New Zealand Red c.oss piloted the Good and Ready initiative in Auc.land,Aotearoa New Zealand, with the objec.ive to empower loc.l people in resilienc. build.ng with a foc.s on volunteers and c.mmunity partic.pation. This researc. examined the positive and negative outc.mes of Good and Ready and investigated volunteers' experienc.s in the disaster resilienc. initiative. It involved the c.design of a questionnaire-based survey using partic.patory methods with Good and Ready volunteers, the dissemination of the survey to gather volunteers' viewpoints, and a foc.s group disc.ssion with partic.patory ac.ivities with Red c.oss volunteers. The find.ngs highlight that a key c.allenge lies in find.ng a balanc. between a program that provides flexibility to address c.ntextual issues and fosters c.mmunities' ownership, versus a presc.iptive and standardized approac. that leaves little room for c.eativity and self-initiative. It pinpoints that supporting volunteers with tec.nic.l training is c.itic.l but that soft skills training suc. as c.ordinating, c.mmunic.ting,or fac.litating ac.ivities at the loc.l level are needed. It c.nc.udes that the sustainability of Good and Ready requires understand.ng and meeting volunteers' motivations and expec.ations and that enhanc.ng partnerships with loc.l emergenc. management agenc.es would strengthen the program.
