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 - 法耶特维尔大学的本杰明·维宁（Benjamin Vining）以及路易斯安那 - 拉法特大学（University of Louisiana-Lafayette），佛罗里达州 - 加恩斯维尔大学（University of Florida Gainesville）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有关。气候变化越来越成为公共和政策问题。这项研究将集中于理解如何使用不同的农业策略，因为过去发生的频率和力量发生了变化。了解农业主义者如何在生产策略之间切换将改善对气候变化的长期适应，为如何解决未来计划和发展中的气候变化提供理论和应用模型，并促进当地的适应能力。将农业作为一组案例研究，可以将这些模型推广到其他形式的经济网络，以了解各种策略如何促进弹性。该项目将建立新的多学科方法，以解决诸如气候变化适应之类的复杂问题，并在国际合作中培训来自合作伙伴机构和国家 /地区的研究生。 Vining博士和他的团队将研究前跨国农业主义者如何在各种生产策略之间发展和切换，因为El Nino Southern振荡（ENSO）的频率和严重性发生了变化。研究区域北海岸秘鲁举办了一系列文明，在公元前2000年至1450年之间，包括摩切，兰巴耶克（Lambayeque）和chimu社会。但是，该地区也尤其容易受到埃尔尼诺（El Nino）诱发的灾难的影响，例如最近发生的2016 - 2017年。该地区的最初考古工作表明，前农业是基于一系列策略。支持前跨社会的复杂经济体部分基于农业策略之间的转变，因为气候环境发生了变化。研究人员来自考古学，古学学和古气候以及生态建模领域。一个主要目标是将农业系统的高精度约会与从湖泊岩心重建的古气候条件相结合。研究人员将使用这种多重方法的方法背景来改善过去ENSO变体的历史性重建，在其环境环境中的农业技术的创纪录的考古示例，并重建了如何用ENSO影响的气候采用不同的策略。该奖项反映了NSF的法定任务，并通过评估企业的构成范围，并反映了概念的支持。
