Biocomplexity Incubation Activity: Human Actions and Land-Use/Land-Cover Change

寻求了解人类与环境之间复杂动态关系的研究人员通常使用在家庭层面收集的普查类型数据，将这些数据汇总到某个地理上界定的行政单位，然后将这些汇总数据与从卫星或飞机上的遥感器收集的土地使用和土地覆盖数据联系起来。 近年来，一些项目系统地设法收集家庭一级的社会经济数据以及遥感土地使用和土地覆盖数据。 这些项目一般都是相互独立的，而且没有认真审查用于实际联系人和像素（遥感器观察到的土地单位）数据的方法。 该生物复杂性孵化奖将支持举办一次讲习班，以解决收集家庭和社区社会经济数据并将其与遥感数据联系起来以研究土地使用和土地覆盖变化所涉及的理论和实际问题。 该项目将使来自许多这些重大项目的科学家讨论研究人员目前面临的方法，挑战和机遇。 讲习班预计将于2001年中至晚些时候在夏威夷檀香山的东西方中心举行。 讲习班与会者编写的文件和讨论情况将用于编写一份出版物，其中将对将基于家庭的社会经济数据与遥感土地使用和土地覆盖数据联系起来的方法和问题进行最新调查。 该项目不仅旨在增进科学界对人类与自然系统之间相互作用的了解。 它还将为决策者提供信息和工具，使他们能够更好地了解人类对土地使用和土地覆盖变化的影响，并预测环境对这种变化的反应。 如果决策者和规划者要创造促进无害环境和可持续发展的条件，了解这些进程至关重要。 更具体地说，拟议的讲习班将有助于更好地了解分析人类对土地使用变化的影响的方法，以及这些变化如何随着时间的推移影响土地覆盖。

Researchers seeking to understand the complex dynamics between humans and their environment commonly have used census-type data that are gathered at the household level, aggregated these data up to some geographically defined administrative unit, and then linked these aggregated data with land-use and land-cover data gathered from remote sensors in satellites or airplanes. In recent years, a number of projects have systematically sought to gather socioeconomic data at the household level as well as remotely sensed land-use and land-cover data. These projects generally have been independent of each other, and there has not been a careful review of the methods being used to actually link data on people and pixels (the units of land as viewed by the remote sensors). This Biocomplexity Incubation Award will support the conduct of a workshop to address both theoretical and practical issues involved in collecting and linking socioeconomic data from households and communities with remotely sensed data to study land-use and land-cover change. This project will bring scientists from a number of these major projects discuss the methods, challenges, and opportunities currently facing researchers. The workshop is expected to be held at the East-West Center in Honolulu, Hawaii, in mid- to late 2001. Papers prepared by and discussions among participants at the workshop will be used to produce a publication that provides a state-of-the-art survey of methodology and issues for linking household-based socioeconomic data with remotely sensed land-use and land-cover data. This project is designed not only to enhance the knowledge of the scientific community regarding the interaction between human and natural systems. It also will provide decision makers with information and tools to enable them to better understand human impacts on land-use and land-cover change and to predict environmental responses to such changes. Understanding these processes is critical if policy makers and planners are to create the conditions that promote environmentally sound and sustainable development. More specifically, the proposed workshop will lead to a better understanding of methods of analyzing human impacts on land-use changes and of how these changes influence land cover over time.
