29 mar 2017 · Interactions between lava flows, whose ages range from 3,000 to 226,000 years, and differences in rainfall create an environmental mosaic that constrained precontact Polynesian farming practices to a zone defined by aridity at low elevation and depleted soil nutrients at high elevation.
30 paź 2019 · Overall, processes of novel forest formation in Polynesia shared key characteristics that affected a suite of activities ranging from subsistence practices to the construction of cultural landscapes. Integration of agroforestry research ultimately provides a nuanced understanding of landscape transformations that are broadly characteristic of ...
We evaluated three potential sources of nutrients to windward systems that could have sustained intensive agriculture: (1) in situ weathering of primary and secondary minerals in upland soils; (2) rejuvenation of the supply of rock-derived nutrients on eroded slopes and in alluvium; and (3) transport of rock-derived nutrients to crops via irriga...
Agriculture was essential in providing for food security, population growth and surplus social production on Pacific Islands. This paper discusses innovations first seen between AD 1400 and 1650 that opened up roughly 60 per cent of the available farm land in the Hawaiian Islands.
The availability of nutrient-rich soils capable of supporting intensive cultivation was a key factor in the relative vulnerability and resilience of traditional Polynesian societies, whose economies were based on agricultural production. We tested.
Polynesian agriculture reached a zenith within Hawaiʻi. More than any other Polynesian islanders, Hawaiians predominantly relied on agriculture rather than marine resources for food (Handy & Handy, 1972). They intensified virtually every arable habitat (Ladefoged
Polynesia—arboriculture, agroforestry, swidden agricultural systems, and shifting cultivation—tend to lack any significant infrastructural footprint (Quintus et al., 2019). In Hawai‘i, sig-nificant population centers that were supported almost entirely by agroforestry cultivation, such as the Puna and Hamākua dis-
