This Research Note provides the first reliable figures on the numbers of seasonal workers from the Pacific Islands who participated in the Recognised Seasonal Employer (RSE) scheme between July 2007 and June 2022. The method for deriving these figures is explained briefly before examining the frequency of return by men and women for employment in subsequent seasons from the nine participating Pacific states. Clarification of the numbers of seasonal workers involved in the scheme, as distinct from work visas issued each year for RSE employment, is timely for two reasons. Firstly, the RSE scheme is under review in March 2023 by Immigration New Zealand. Secondly, the three major sources of Pacific seasonal labour are raising questions in 2023 about the impact of the scheme on their domestic labour markets and economies. Robust data on numbers of Pacific seasonal workers during the scheme's first 15 years contributes important information in both these contexts. 相似文献

Fossil midge remains in a sediment core from Lake Stowell, a low-elevation lake in coastal British Columbia, Canada, were used to assess temporal changes in chironomid communities and to produce quantitative estimates of mean July air temperature (MJAT) for the past 14,000 years based on two different transfer functions. Chironomid assemblages are diverse throughout much of the record, with most taxa present at low relative abundances. The basal portion of the sediment record is characterized by low head capsule concentrations, taxonomic diversity and organic matter content, all of which increase towards the early Holocene. Inferred temperatures suggest a cool late-glacial interval with a minimum MJAT of 12.5 °C, ~2 °C cooler than the inferred modern temperature. Summer temperatures gradually increased from this minimum until a brief cooling of as much as ~3 °C relative to modern that coincides with the Younger Dryas chronozone. An interval of warmer summers with MJAT of ~16 to 18 °C (2–3 °C warmer than modern) is inferred between ~10,500 and 8000 cal year BP. This early Holocene warm period was followed by generally cooler inferred temperatures in the middle and late Holocene. The midge-inferred temperature record from Lake Stowell is generally consistent with other temperature reconstructions from the region based on chironomid remains and other climate proxies. This research underscores the potential of low-elevation, mid-latitude sites for chironomid-based temperature reconstructions. In order to maximize the availability of modern analogues for robust temperature reconstructions from similar sites, calibration datasets should be expanded to include more sites from the warm end of the temperature gradient. 相似文献

The specific character of soil cover in the territory of the Democratic People’s Republic of Korea (DPRK) is revealed, and the soil interpretation schemes in the key areas are compiled. It is established that the main soil resource for agriculture within the region’s low and middle mountains is provided by areas of weakly developed brown forest soils in the lower parts of slopes as well as by alluvial soils along the valleys of large and medium-sized rivers. Specifically, brown forest soils of slopes are used largely in dry farming and forestry, while soils along river valleys are utilized in rice cultivation. Soils of terraced slopes and rice fields have been transformed anthropogenically to the greatest extent. 相似文献
