The observed global warming has significant impacts on permafrost. Permafrost changes modify landscapes and cause damage to infrastructure. The main purpose of this study was to estimate permafrost temperatures and active-layer thicknesses during the Holocene intervals with significantly warmer-than-present climates—the Atlantic (5500 years BP), Subboreal (3500 years BP) and Subatlantic (1000 years BP) optimums. Estimates were obtained using the ready-to-use models derived by G.M. Feldman, as well as mathematical modeling taking account of the paleogeography of the Holocene warm intervals.
Changes in the Function of Allotment Gardens in an Attractive Location Based on the Example of Tri-City in Poland
Allotment gardens are quite common in many European countries. In particular, they are an important part of the urban space in Central and Eastern Europe. They served to improve the inhabitants’ physical and mental well-being during the communist period and relieved the family budget thanks to their own crops. The article analyzes the functioning of allotment gardens in Poland based on the example of the Tri-City, with particular emphasis on allotment gardens in a prestigious, attractive location.
The Value Assessment and Planning of Industrial Mining Heritage as a Tourism Attraction: The Case of Las Médulas Cultural Space
This article analyzes the heritage construction process or “heritagization” of Las Médulas gold mines, a prime example of how Spain’s mining heritage has been reused for tourism purposes. Based on a methodology combined documentary analysis and fieldwork, informal interviews with territorial actors and surveys targeting residents, this study addresses the complexities of integrating this cultural landscape into a tourism development strategy and analyzes the support and impacts perceived by the local population.
Prescribed Burning as A Management Tool to Destroy Dry Seeds of Invasive Conifers in Heathland in Denmark
Non-indigenous conifers are considered invasive to the coastal dune heathland in Denmark, and massive clearing is carried out in an attempt to recreate and keep the original heathland. Burning is a common method for managing, but its feasibility to control the seed bank of conifers has not been investigated. This project shows that the burning of logged conifer trees will often eliminate seeds of lodgepole pine, mugo pine and Sitka spruce, even when the seeds were placed into a depth of five centimeters in the soil.
Mapping Conservation Management Practices and Outcomes in the Corn Belt Using the Operational Tillage Information System (OpTIS) and the Denitrification–Decomposition (DNDC) Model
Identifying and quantifying conservation-practice adoption in U.S. cropland is key to accurately monitoring trends in soil health regionally and nationally and informing climate change mitigation efforts. We present the results of an automated system used across 645 counties in the United States Corn Belt from 2005 to 2018, mapped at field-scale and summarized for distribution at aggregated scales.
