We are very sorry to have to say farewell to our colleague Professor Helen Young, who is stepping back from her role as co-editor of Disasters. Helen joined the journal in 1997, offering a wealth of expertise across a vast range of subjects, with a particular focus on nutrition, livelihoods, and resilience in emergencies. During a rich career spanning the NGO (non-governmental organisation) sector, the United Nations (UN), and academia, especially as Research Director at the Feinstein International Center, and entailing the production of dozens of publications, Helen has been a leading voice in the sector, helping to shape a raft of technical guidelines, standards, and indicators and driving forward academic debate and evidence-based research.

As co-editors of Disasters, we are hugely grateful to Helen for not only the rigorous but sympathetic approach she brought to the journal, but also for being an active contributor to it in her own right. Her first article, on the development of aid agency policy on the use of imported biscuits in emergency relief, appeared in 1986. Contributions since have included an analysis of selective feeding programmes in Ethiopia and East Sudan (volume 11, issue 2, 1987), a review of public nutrition in emergencies (volume 23, issue 4, 1999), and reflections on the Sphere Project and the Humanitarian Charter and Minimum Standards in Disaster Response (with Paul Harvey; volume 28, issue 2, 2004). Alongside seminal work in the mid-1990s on the relationship between nutrition, disease, and mortality in famine (with Susanne Jaspars; volume 19, issue 1, 1995), Helen's abiding interest in food security and livelihoods in Darfur is reflected in a series of contributions covering livelihoods and protection (volume 31, issue S1, 2007), participation, political economy, and protection in food aid governance (with Daniel Maxwell; volume 37, issue 4, 2013), and livelihood resilience (with Musa Adam Ismail; volume 43, issue S3, 2019). Helen also published in other journals, ranging from Development and Change to the International Migration Review, Land Use Policy, and the Food and Nutrition Bulletin. Given her aim of linking research evidence to policy, she published a number of Feinstein policy reports and briefing papers and organised numerous dissemination events in Sudan and elsewhere around the world. As part of her work, she has taken a leading role in localising research in Sudan. We have no doubt she will continue to publish and influence others.

We will sorely miss Helen, but are delighted that Dr Susanne Jaspars, who has been on our editorial board for many years, has agreed to join the editorial team in Helen's stead. Susanne has more than 30 years' experience working on the political dynamics of food security, livelihoods, and forced migration in situations of conflict, famine, and humanitarian crisis. Her expertise is predominantly in the Horn of Africa, but her recent work also includes Europe. Susanne has worked as a humanitarian practitioner for organisations including Médecins Sans Frontières, Oxfam, and the UN's World Food Programme, as well as conducting applied research as a Visiting Fellow at the Institute of Development Studies and as a Senior Research Fellow with the Humanitarian Policy Group at ODI. Susanne completed her PhD in 2016 (on the history and politics of food aid in Sudan) and is currently an independent researcher and a Research Associate at the SOAS Food Studies Centre. She continues to research the political economy of food, social nutrition, and the politics of migration to—and asylum in—Europe, and is Vice-President of the International Humanitarian Studies Association. Susanne has published a number of books and policy reports, as well as articles in a range of journals, including Disasters.

我们很遗憾不得不向我们的同事 Helen Young 教授告别，她将辞去她作为Disasters联合主编的职务。Helen 于 1997 年加入该杂志，在广泛的主题中提供了丰富的专业知识，特别关注营养、生计和紧急情况下的复原力。在跨越非政府组织（非政府组织）部门、联合国 (UN) 和学术界的丰富职业生涯中，尤其是作为范斯坦国际中心的研究主任，并出版了数十种出版物，海伦一直是领军人物在该领域，帮助制定大量技术指南、标准和指标，并推动学术辩论和循证研究。

作为《灾难》的联合主编，我们非常感谢海伦，不仅因为她为杂志带来的严谨而富有同情心的方法，而且因为她自己也成为了积极的贡献者。她的第一篇文章，关于在紧急救济中使用进口饼干的援助机构政策的制定，发表于 1986 年。此后的贡献包括对埃塞俄比亚和东苏丹选择性喂养计划的分析（第 11 卷，第 2 期，1987 年），紧急情况下的公共营养回顾（第 23 卷，第 4 期，1999 年），以及对 Sphere 项目和人道主义宪章和灾害应对最低标准的思考（与 Paul Harvey 合着；第 28 卷，第 2 期，2004 年）。除了 1990 年代中期关于饥荒中营养、疾病和死亡率之间关系的开创性工作（与 Susanne Jaspars 合着；第 19 卷，第 1 期，1995 年），Helen' 对达尔富尔粮食安全和生计的持久兴趣反映在一系列的贡献中，包括生计和保护（第 31 卷，第 S1 期，2007 年）、参与、政治经济和粮食援助治理中的保护（与 Daniel Maxwell；第 37 卷， 2013 年第 4 期）和生计复原力（与 Musa Adam Ismail 合着；第 43 卷，第 S3 期，2019 年）。海伦还在其他期刊上发表过文章，范围从国际移民审查、土地使用政策和食品和营养公报的发展和变化。鉴于她将研究证据与政策联系起来的目标，她发表了许多范斯坦政策报告和简报，并在苏丹和世界其他地方组织了许多传播活动。作为她工作的一部分，她在苏丹本土化研究方面发挥了主导作用。我们毫不怀疑她将继续发表文章并影响他人。

我们非常想念 Helen，但很高兴在我们编辑委员会任职多年的 Susanne Jaspars 博士同意代替 Helen 加入编辑团队。Susanne 在冲突、饥荒和人道主义危机情况下的粮食安全、生计和被迫迁移等政治动态方面拥有 30 多年的工作经验。她的专长主要在非洲之角，但她最近的工作还包括欧洲。Susanne 曾在无国界医生组织、乐施会和联合国世界粮食计划署等组织担任人道主义实践者，并作为发展研究所的访问研究员和人道主义政策小组的高级研究员进行应用研究在 ODI。Susanne 于 2016 年完成了博士学位（关于苏丹粮食援助的历史和政治），目前是 SOAS 食品研究中心的独立研究员和研究助理。她继续研究食品的政治经济学、社会营养学以及移民到欧洲和在欧洲避难的政治学，并且是国际人道主义研究协会的副主席。Susanne 出版了许多书籍和政策报告，以及在一系列期刊上发表的文章，包括灾难。
