Abstract

Many communities in southwestern Madagascar rely on a mix of foraging, fishing, farming, and herding, with cattle central to local cultures, rituals, and intergenerational wealth transfer. Today these livelihoods are critically threatened by the intensifying effects of climate change and biodiversity loss. Improved understanding of ancient community-environment dynamics can help identify pathways to livelihood sustainability. Multidisciplinary approaches have great potential to improve our understanding of human-environment interactions across spatio-temporal scales. We combine archaeological survey data, oral history interviews, and high-resolution multispectral PlanetScope imagery to explore 400 years of human-environment interaction in the Namonte Basin. Our analysis reveals that settlement and land-use led to significant changes in the region's ecology, both during periods of occupation and after settlement abandonment. Human activity over this period may have stabilized vegetative systems, whereby seasonal changes in vegetative health were reduced compared to surrounding locations. These ecological legacies may have buffered communities against unpredictable climate challenges.

考古学、人种学和地球科学揭示了传统生活方式在塑造马达加斯加干旱森林中的核心作用。
马达加斯加西南部的许多社区以觅食、捕鱼、耕作和放牧为生,牛是当地文化、仪式和代际财富传承的核心。如今,气候变化和生物多样性丧失的影响日益加剧,这些生计受到严重威胁。加强对古老社区-环境动态的了解有助于确定生计可持续性的途径。多学科方法在提高我们对人类与环境跨时空尺度互动的理解方面具有巨大潜力。我们将考古调查数据、口述历史访谈和高分辨率多光谱 PlanetScope 图像结合起来,探索纳蒙特盆地 400 年来人类与环境的互动。我们的分析表明,定居和土地使用导致该地区的生态环境发生了重大变化,无论是在占领时期还是在定居放弃之后。这一时期的人类活动可能稳定了植被系统,与周围地区相比,植被健康状况的季节性变化减少了。这些生态遗产可能使社区免受不可预测的气候挑战的影响。

期刊介绍: The Journal of Social Archaeology is a fully peer reviewed international journal that promotes interdisciplinary research focused on social approaches in archaeology, opening up new debates and areas of exploration. It engages with and contributes to theoretical developments from other related disciplines such as feminism, queer theory, postcolonialism, social geography, literary theory, politics, anthropology, cognitive studies and behavioural science. It is explicitly global in outlook with temporal parameters from prehistory to recent periods. As well as promoting innovative social interpretations of the past, it also encourages an exploration of contemporary politics and heritage issues.
