项目摘要

This Doctoral Dissertation Research Improvement project will examine dryland irrigation megaprojects and related changes in the use and governance of water and irrigated land. Irrigation megaprojects in arid landscapes feature prominently in agricultural development worldwide. Planning and policy entities often focus on the economic benefits of irrigation water for farmers. However, irrigated soils are often central to ecological and social conflicts that follow the construction of irrigation districts. Such conflicts include reduced soil quality, water contamination via agricultural runoff, and displacement of regional farmers by investors' large land acquisitions. Therefore, this research will investigate the social and ecological effects of irrigation megaprojects and the related governing policies and practices of irrigation water and soils. This research will contribute to scholarly and policy considerations of social-environmental feedbacks in governance. The broader impacts of this project will (1) work toward improved irrigation infrastructure development, (2) strengthen management of irrigated land to ensure increased sustainability of soil and water resources, and (3) encourage policy that ensures more equitable access to irrigated land. During this research diverse university students will receive training in mixed methods research. This Doctoral Dissertation Research Improvement award will provide support to enable a promising student to establish an independent research career. This dissertation investigates the interactions and feedbacks between irrigation megaprojects, soil management practices, and soil and water governance. Scholarship of environmental governance related to irrigation has focused on issues of water access and control. While important, more scholarly attention must examine the centrality of soils within irrigation megaprojects. The coupling of and tensions between water and soil use and governance require detailed empirical examination that leverages key literatures within geography and the spatial sciences, particularly environmental governance, coupled human-environment systems, and feminist political ecology. Three questions guide this research: (1) How does access to water from irrigation megaprojects shape soil management practices, specifically crop selection, crop rotations, and applications of agrochemicals? (2) How do social and environmental stressors inform soil management practices? (3) How do social and environmental stressors feedback into environmental governance? This research employs a mixed methods approach including change detection analysis, environmental archival research, participant observation, a survey, farm transect walks, and semi-structured interviews with farmers, irrigation managers, and government officials. This research project will provide new insights regarding sustainable and equitable approaches to irrigation development and governance in dryland areas in Colombia and elsewhere, including the United States.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.

该博士学位论文研究改进项目将检查旱地灌溉大型注射及水和灌溉土地的使用和治理的相关变化。在全球农业发展中，干旱景观中的灌溉大型投资在全球范围内突出。计划和政策实体通常集中于农民灌溉水的经济利益。但是，灌溉土壤通常是灌溉区建设后的生态和社会冲突的核心。这些冲突包括降低土壤质量，通过农业径流污染水以及投资者大型土地收购对区域农民的流离失所。因此，这项研究将研究灌溉的社会和生态影响，以及灌溉水和土壤的相关政策和实践。这项研究将有助于治理中社会环境反馈的学术和政策考虑。该项目的更广泛影响将（1）努力改善灌溉基础设施的发展，（2）加强对土地的管理，以确保土壤和水资源的可持续性增加，以及（3）鼓励确保更公平地获得灌溉土地的政策。在这项研究中，多样化的大学生将接受混合方法研究的培训。该博士学位论文研究改进奖将提供支持，以使有前途的学生能够建立独立的研究职业。本文研究了灌溉，土壤管理实践以及土壤和水治理之间的相互作用和反馈。与灌溉相关的环境治理奖学金集中在水的问题问题上。虽然重要，但更多的学术关注必须检查灌溉大型注射中土壤的中心性。水与土壤使用与治理之间的耦合和紧张关系需要详细的经验检查，以利用地理学和空间科学，尤其是环境治理，人类环境系统以及女权主义政治生态学的关键文献。指导这项研究的三个问题：（1）如何从灌溉中获得水的含水来塑造土壤管理实践，特别是农作物的选择，农作物的轮作和农业化学物质的应用？（2）社会和环境压力源如何为土壤管理实践提供信息？（3）社会和环境压力源如何反馈对环境治理？该研究采用了一种混合方法方法，包括变更检测分析，环境档案研究，参与者观察，调查，农场横断面步行以及对农民，灌溉经理和政府官员的半结构化访谈。该研究项目将提供有关哥伦比亚和其他地方（包括美国）旱地地区灌溉发展和治理的可持续和公平方法的新见解。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估标准来通过评估来进行评估的。
