Identifying human and nonhuman factors that influence soil degradation helps develop policies, practices, and social institutions that do not undermine vital soil productivity functions. Human impact on a soil's ability to buffer against pH shifts (acid neutralizing capacity or ANC) is generally understudied, even though decreasing ANC (acidification) can result in degraded water quality and a loss of soil fertility. Few attempts have been made to understand the connection between social institutions and soil degradation in East Central Europe . Major social changes since the late 1980s make this region especially appropriate for discerning linkages between environmental impact and social institution. Unfortunately, research remains largely limited to pre-1989 human impact at national scales and continues to ignore the effects of nonhuman factors. The objective of this project is to investigate the interaction between farming and soil ANC in SW Hungary. The study will consider whether and how farming, other human activities, or nonhuman processes lead to changes in ANC and, if farming is the main cause, whether local or larger-scale processes mostly affect farming practices. Data will be gathered, processed, and entered into a GIS with the aid of Hungarian and U.S. assistants through the following activities: semi-structured interviews, soil and manure sampling and analysis for commercial and subsistence plots, and archival and documentary research on regional atmospheric deposition, soil monitoring, land use, socio-economic factors, and local histories. Using largely multivariate statistical techniques, the investigator will assess rates of change in soil ANC, identifying the principal influencing factors, and determining the degree to which ANC can be explained by local environmental practices.The project results will help evaluate theories of environmental degradation in East Central Europe by investigating the relationship between local management practices and soil conditions. The project's larger impact will be to broaden the purview of both social and physical sciences by combining theoretical and methodological approaches. The database and GIS exercises generated from the findings will enhance course content for students at SUNY-New Paltz. Underrepresented groups will be involved by recruiting Roma ("Gypsies"), who rarely figure as scientific researchers, and women, whose representation is especially rare in the physical sciences. Rural development projects in Hungary will be sensitized to the pitfalls of ignoring differential access to and control over agricultural resources and to the skills and knowledge of the local Roma minority. Finally, the project will contribute to the understanding of the active roles of nonhuman factors in human-induced environmental change in order to help devise sounder environmental policy and practice at local, national, and European Union levels.

确定影响土壤退化的人为和非人为因素有助于制定不会破坏土壤生产力重要功能的政策、做法和社会制度。人类对土壤缓冲pH值变化的能力（酸中和能力或ANC）的影响通常没有得到充分研究，尽管ANC（酸化）的降低会导致水质退化和土壤肥力的丧失。很少有人试图了解东中欧的社会制度与土壤退化之间的联系。1980年代后期以来的重大社会变化使该区域特别适合于辨别环境影响和社会体制之间的联系。不幸的是，研究仍然主要局限于1989年以前在国家尺度上的人类影响，并继续忽视非人为因素的影响。该项目的目的是调查匈牙利西南部农业和土壤ANC之间的相互作用。该研究将考虑农业、其他人类活动或非人类过程是否以及如何导致ANC的变化，如果农业是主要原因，则是当地或更大规模的过程主要影响农业实践。在匈牙利和美国助手的帮助下，将通过以下活动收集、处理数据，并将其输入地理信息系统：半结构化访谈，对商业和生计地块进行土壤和粪便取样和分析，以及对区域大气沉积、土壤监测、土地利用、社会经济因素和当地历史进行档案和文献研究。利用多变量统计技术，研究者将评估土壤ANC的变化率，确定主要影响因素，并确定ANC可以用当地环境实践解释的程度。该项目的结果将通过调查当地管理做法与土壤条件之间的关系，帮助评价东欧环境退化的理论。该项目更大的影响将是通过结合理论和方法方法来扩大社会科学和物理科学的范围。从调查结果中产生的数据库和GIS练习将提高纽约州立大学-新帕尔茨分校学生的课程内容。未被充分代表的群体将通过招募罗姆人（“吉卜赛人”）和女性参与进来，罗姆人很少成为科学研究人员，而女性在物理科学领域的代表尤其罕见。匈牙利的农村发展项目将敏感地认识到忽视差别获取和控制农业资源以及当地罗姆少数民族的技能和知识的陷阱。最后，该项目将有助于了解非人为因素在人为引起的环境变化中的积极作用，以帮助在地方、国家和欧洲联盟各级制定更健全的环境政策和做法。
