• Clarifying ambiguity: a reassessment of the multi-disciplinary evidence for a 10,000 year-old palaeosurface at Kuk Swamp, highlands of Papua New Guinea

  A 10,000-year-old palaeosurface at Kuk Swamp in the highlands of Papua New Guinea provides compelling evidence for one of the earliest forms of shifting cultivation. This study re-evaluates multi-disciplinary data—including direct archaeological findings and palaeo-pedological indicators—to clarify whether this ancient land use represents shifting cultivation or alternative plant exploitation practices. By integrating palaeoecological and geomorphological evidence, researchers reconstruct landscape transformation linked to human activity, offering new insights into the origins of agricultural adaptation in tropical environments.

• Processing of Pueraria montana var. lobata (kudzu bean) and Colocasia esculenta (Taro ) during the early holocene at kuk swamp in the papua new guinea highlands

  A groundbreaking analysis of stone artefacts from Kuk Swamp, Papua New Guinea, reveals the earliest use of kudzu bean (Pueraria montana var. lobata) and taro (Colocasia esculenta) in the highlands during the Early Holocene (c. 10,000 years ago). The study employed robust statistical methods, categorical attributes, and expert input to identify these plants from starch grains on a flaked stone tool (K/76/S29B), addressing long-standing challenges in attributing unknown residues to specific plant taxa. Notably, the research found that taro and Dioscorea esculenta share indistinguishable starch grain morphologies, necessitating additional distinguishing features such as cultural use, growing requirements, and sedimentary context for accurate identification. This work underscores the significance of integrating multiple lines of evidence in reconstructing ancient plant exploitation, offering new insights into the dietary practices of early highland communities.

• Late Quaternary history of the Gumants catchment, Papua New Guinea

  A massive debris avalanche, estimated to be over 15 km³ and occurring around 400 ± 100 thousand years ago (ka), reshaped the Gumants catchment in Papua New Guinea's central highlands. This geological event altered the flow of the Upper Gumants River, which once connected directly to the Wahgi River via the Guga subcatchment—home to Kuk Swamp, a UNESCO World Heritage Site renowned for its 10,000-year history of agriculture. The study reveals that volcanic deposits, including lahars and airfall tephras (last active ~200 ka), dominate the landscape, with swamp sediments in the Kugimi Basin reaching depths of at least 30 meters—beyond radiocarbon dating limits. Contrary to past speculation, evidence confirms the Gumants River has always flowed eastward, likely joined by the Wahgi River, challenging previous assumptions about their drainage history.

• A Feast of Diversity

  Agriculture did not emerge uniformly; its development varied significantly across regions. The study highlights the distinct paths of agricultural origins in Africa, New Guinea, the Andes, and East Asia, emphasizing regional differences in timing, practices, and cultural impacts. In Africa, pastoralism played a crucial role, while pottery introduction marked significant changes. Kuk Swamp in New Guinea offers evidence of early domestication linked to village life. The Andes show a relationship between quinoa cultivation and highland environments, whereas China's dual centers of domestication—Cishan and Jiahu—demonstrate diverse agricultural adaptations. This comparative analysis challenges the notion of a single trajectory for agricultural development.

• The origins and development of New Guinea agriculture

  Archaeological evidence from the Kuk Early Agricultural Site in New Guinea challenges traditional assumptions about agricultural origins in the South Pacific, supporting claims for agriculture dating back approximately 6000 years. This finding aligns with the presence of domesticated pigs, an introduced species, which are often associated with early agricultural practices across the Pacific. The study proposes an independent development of agriculture in New Guinea, rooted in the domestication of a diverse suite of plants—including staples, vegetables, and fruits—that could sustain populations in varied environments. Given the absence of botanical remains, researchers relied on traditional crop cultivation patterns to reconstruct this agricultural history, offering a compelling narrative for the region's early subsistence strategies.

• Ten thousand years of cultivation at Kuk Swamp in the highlands of Papua New Guinea,

  Archaeological evidence from Kuk Swamp, a UNESCO World Heritage Site in Papua New Guinea's highlands, reveals the world's earliest known agricultural practices dating back 10,000 years. This discovery challenges previous assumptions about the origins of agriculture, suggesting it emerged independently and earlier than thought in other regions. The study employed stratigraphic excavation and radiocarbon dating to analyze sediment layers, uncovering tools, plant remains, and other artifacts that indicate systematic cultivation of taro, yams, and other staples. These findings underscore the significance of Kuk Swamp as a cradle of human innovation, with profound implications for understanding the transition from foraging to farming societies.

• Origin and Development of Agriculture in New Guinea, Island Melanesia, and Polynesia

  Agriculture in the Pacific Islands began with early Holocene practices centered on vegetative propagation and underground storage organs, later evolving into complex systems. Kuk Swamp in Papua New Guinea's highlands offers one of the earliest records of agricultural intensification, showing mounded cultivation around 7000–6400 cal BP and wetland drainage by 4400–4000 cal BP. Unlike other regions in Near Oceania, which focused on fruit- and nut-bearing trees, Kuk’s landscape reveals a shift toward more intensive land management. By 3250–2800 cal BP, these practices spread with Lapita pottery-bearers into the western Pacific, while later Polynesian colonization (1000–750 cal BP) introduced new crops like the sweet potato, reshaping regional agriculture.
