项目摘要

Dr. Benjamin Vining, of the University of Arkansas-Fayetteville, along with collaborators from the University of Louisiana-Lafayette, the University of Florida-Gainesville, and in Peru, will examine how the organization of different agricultural production systems relates to climate change vulnerabilities. Climate change is increasingly a public and policy concern. This research will focus on understanding how different agricultural strategies were used as el Nino disasters occurred in the past with changing frequency and strength. Understanding how agriculturalists switched between productive strategies will improve long-term adaptations to climate change, provide theoretical and applied models for how to address climate change in future planning and development, and promote local adaptive capacities. Using agriculture as a set of case studies, these models can be generalized to other forms of economic networks to understand how various strategies can promote resilience. This project will establish new multidisciplinary approaches to tackle such complex problems as climate change adaptation, and train graduate students from the partner institutions and countries in international collaborations. Dr. Vining and his team will examine how prehispanic agriculturalists developed and switched between various productive strategies as the el Nino Southern Oscillation (ENSO) changed in frequency and severity. The study region, north coastal Peru, hosted a series of civilizations between approximately 2000 BC - 1450 AD, including the Moche, Lambayeque, and Chimu societies. However, the region is also particularly vulnerable to el Nino induced disasters, such as occurred recently in 2016-2017. Initial archaeological work in this region indicates that prehispanic agriculture was based on a suite of strategies. The complex economies that supported prehispanic societies were based on in part on switching amongst agricultural strategies as climatic contexts shifted. The researchers come from the fields of archaeology, paleolimnology and palaeoclimate, and ecological modeling. A principal objective will be to combine high-precision dating of agricultural systems with paleoclimate conditions reconstructed from lake cores. The researchers will use this multidisplinary methodological background to improve historic reconstructions of past ENSO variations, record archaeological examples of agricultural technologies in their environmental context, and reconstruct how different strategies were employed as ENSO effected climate.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

阿肯色大学费耶特维尔分校的本杰明·维宁博士与路易斯安那大学拉斐特分校、佛罗里达大学盖恩斯维尔分校和秘鲁的合作者将研究不同农业生产系统的组织如何与气候变化脆弱性相关。气候变化日益成为公众和政策关注的焦点。这项研究将重点了解过去发生频率和强度不断变化的厄尔尼诺灾害时如何采用不同的农业策略。了解农民如何在生产策略之间进行转换将改善对气候变化的长期适应，为未来规划和发展中如何应对气候变化提供理论和应用模型，并提高当地的适应能力。使用农业作为一组案例研究，这些模型可以推广到其他形式的经济网络，以了解各种策略如何提高复原力。该项目将建立新的多学科方法来解决气候变化适应等复杂问题，并培训来自伙伴机构和国家的研究生进行国际合作。维宁博士和他的团队将研究随着厄尔尼诺南方涛动 (ENSO) 频率和严重程度的变化，西班牙裔前的农业学家如何制定各种生产策略并在其之间进行转换。研究区域位于秘鲁北部沿海，大约在公元前 2000 年至公元 1450 年期间出现了一系列文明，包括莫切、兰巴耶克和奇穆社会。然而，该地区也特别容易受到厄尔尼诺现象引发的灾害的影响，例如最近在 2016-2017 年发生的灾害。该地区的初步考古工作表明，前西班牙时期的农业基于一套策略。支持前西班牙社会的复杂经济部分基于随着气候环境的变化而改变的农业战略。研究人员来自考古学、古湖泊学和古气候以及生态模型领域。主要目标是将农业系统的高精度测年与从湖芯重建的古气候条件结合起来。研究人员将利用这种多学科方法背景来改进过去 ENSO 变化的历史重建，记录环境背景下农业技术的考古实例，并重建 ENSO 影响气候时如何采用不同的策略。该奖项反映了 NSF 的法定使命，并被视为值得通过使用基金会的智力优点和更广泛的影响审查标准进行评估来支持。
