项目摘要

This is a proposal to continue a unique micro·level study of the reciprocal relationships between population processes (marriage, fertility, and migration) and the environment (land usefcover, vegetation abundance and species diversity, and consumption of natural resources) in the foothills of the Nepalese Himalayas. To date analyses of these data have revealed a series of crucial insights into the overall reciprocal relationships between population and the environment. First, we find key dimensions of environmental variation do shape subsequent marital, childbearing, and migration behavior, but these population parameters also influence change and variation in land use, vegetation abundance, species diversity, and consumption of natural resources. Second, at the micro· level we find that local community context conditions the population· environment relationship, with strong effects on marriage, childbearing and migration on the one hand and land use, vegetation and consumption behavior on the other hand. Third, our investigation of the micro· level processes linked to these associations points toward variations in consumption behavior and perceptions of environmental change as key mechanisms linking population parameters and environmental change. Although these findings shape the theoretical model guiding our research, updated longitudinal data just available now provides a significant opportunity to advance research in this field.

这是一项建议，继续在尼泊尔喜马拉雅山山麓丘陵地带对人口过程（婚姻、生育和迁移）与环境（土地利用/覆盖、植被丰富度和物种多样性以及自然资源消耗）之间的相互关系进行独特的微观研究。迄今为止，对这些数据的分析揭示了对人口与环境之间总体相互关系的一系列重要见解。首先，我们发现环境变化的关键维度确实影响了随后的婚姻，生育和迁移行为，但这些人口参数也影响了土地利用，植被丰度，物种多样性和自然资源消耗的变化和变化。第二，在微观层面上，我们发现地方社区环境对人口与环境的关系起着决定性的作用，一方面对婚姻、生育和迁移有着重要的影响，另一方面对土地利用、植被和消费行为也有着重要的影响。第三，我们对与这些关联相关的微观过程的研究指出，消费行为和对环境变化的感知的变化是联系人口参数和环境变化的关键机制。虽然这些发现塑造了指导我们研究的理论模型，但现在更新的纵向数据为推进这一领域的研究提供了重要机会。
