Abstract The arable‐pastoral ecotone in northern China is ecologically fragile and the region has experienced substantial climatic variability, triggering population migrations, alternation of subsistence strategies during historical period. However, lack continuous proxy records arable grazing activity hampered our understanding shifts their relationship with societal changes. We obtained Sporormiella ‐type spores crop pollen from Gonghai Lake to reconstruct changes cultivation intensity over past approximately 2000 years. results show that intensive occurred Sui early‐middle Tang Dynasties (581–820 CE), when there was a relatively favourable climate, harmonious ethnic relations, strong central government control. Conversely, weakened agricultural late Dynasty (820–907 CE) corresponded deteriorating climate frequent wars. High temperatures Song (960–1127 promoted expansion land mountainous areas, whereas cold crises Era Disunity (220–580 Ming‐Qing (1368–1912 limited cultivated shift as activity. Time‐series analysis reveals farming phases had longer periodicity than phases, possibly because greater resilience former change attachment agriculturalists land. Our findings potentially help improve impact use on soil degradation.

Sahara’s surface transformation forced an abrupt hydroclimate decline and Neolithic culture transition in northern China

The Innovation, Journal Year: 2023, Volume and Issue: 5(1), P. 100550 - 100550

The remote forcing from land surface changes in the Sahara is hypothesized to play a pivotal role modulating intensity of East Asian summer monsoon (EASM) through ocean-atmospheric teleconnections. This modulation has far-reaching consequences, particularly facilitating societal shifts documented northern China. Here, we present well-dated lake-level record Daihai Lake Basin China, providing quantitative assessments Holocene monsoonal precipitation and consequent migrations boundary EASM. Our reconstruction, informed by water-and-energy balance model, indicates that annual reached ∼700 mm during 8-5 ka, followed rapid decline ∼550 between 5 4 ka. shift coherently aligns with significant ∼300 km northwestward movement EASM Middle (MH), contrast its current position. findings underscore these cannot be entirely attributed orbital forcing, as corroborated simulation tests. Climate model simulations deployed our study suggest presence Green MH significantly strengthened led northward rainfall belt. Conversely, Sahara's reversion desert landscape late was accompanied corresponding southward retraction influence. These dramatic hydroclimate ∼5-4 ka likely triggered or at least contributed Neolithic cultures transformation With decreasing agricultural productivity, communities transitioned millet farming mixed rainfed agriculture animal husbandry system. Thus, elucidate not only variability but also profound implications such transformations Sahara, on climatic cultural evolution
