As we address the grand challenges of our time, inclusivity and representation become key success factors. This study examined the geodiversity of researchers through a case study of publications related to the United Nations SDG 2 - Zero hunger. We assumed topical focus if a country was mentioned in the title or abstract of an article. We also determined author location through their institutional affiliation. We organised 60,000 hunger-related publications by country focus and by country affiliation according to the 2021 Global Hunger Index country categories. This revealed insights into the share of research into hunger conducted by academics based in affected areas and the relationship between local and international researchers. Only 41% of hunger-related publications that focus on countries in the GHI alarming or extremely alarming categories feature authors affiliated to institutions in those countries. Even fewer of those publications feature locally based authors in first or last position. These numbers gradually reverse as the level of hunger declines. We urge caution before leaping to conclusions related to helicopter research based on author affiliations and authorship position. A manual examination of randomly sampled papers suggests that many underlying factors contribute to the overall trends.

翻译：在应对当今重大挑战时，包容性与代表性成为关键成功因素。本研究以联合国可持续发展目标2（零饥饿）相关出版物为案例，考察研究者的地理多样性。我们以某国在论文标题或摘要中被提及作为研究聚焦国别的判定依据，并通过作者所属机构确定其所在地。根据2021年全球饥饿指数国家分类，我们对6万篇饥饿相关论文按关注国别和作者所属国别进行了归类。研究发现：在受饥饿影响地区开展的相关研究占比情况，以及本土与国际研究者之间的合作模式。在关注全球饥饿指数中"令人警惕"或"极度警惕"类别国家的论文中，仅41%包含受关注国别机构作者的研究。在这些论文中，由本土学者担任第一作者或通讯作者的比例更低。随着饥饿严重程度递减，上述数据呈现逐步逆转趋势。我们呼吁谨慎依据作者所属机构及其署名位次得出"直升机研究"的结论。对随机抽样论文的手工审查表明，整体趋势背后存在多重潜在因素。
