Global agroecosystems, predominantly pastoral and rangelands, are crucial for food, fibre, carbon sequestration, and biodiversity, covering about 40-50 % of Earth's land. Yet, they are also sources of greenhouse gas emissions, soil erosion, and land degradation. In New Zealand, nearly half the land supports grazing ruminants, significantly impacting the environment and contributing to methane and nitrous oxide emissions. Accurate livestock population data are essential to understand and mitigate these impacts.

以高分辨率量化牧区农业生态系统中畜牧种群的空间分布和时间趋势


全球农业生态系统，主要是牧场和牧场，对于食物、纤维、碳封存和生物多样性至关重要，覆盖了地球约 40-50% 的土地。然而，它们也是温室气体排放、水土流失和土地退化的来源。在新西兰，近一半的土地支持着放牧的反刍动物，这对环境产生了重大影响，并导致了甲烷和一氧化二氮的排放。准确的畜牧种群数据对于了解和减轻这些影响至关重要。
