High landscape diversity is assumed to increase the number and level of ecosystem services. However, the interactions between ecosystem service provision, disturbance and landscape composition are poorly understood. Here we present a novel approach to include uncertainty in the optimization of land allocation for improving the provision of multiple ecosystem services. We refer to the rehabilita...
The endemic tree Acacia koa is used to reforest abandoned agricultural lands in Hawaii. Growth may be constrained by soil infertility and toxic concentrations of aluminum (Al) and manganese (Mn) in acidic Oxisols and Ultisols. The effects of phosphorus (P) fertilization at time of planting, soil type, and seed source on koa growth were studied for three years. Phosphorus, applied as triple supe...
The article considers the spectral response of post-agrogenic landscapes in forest-steppe zone based on Sentinel-2 data. study was carried out territory Central Chernozem region. type forest that forms abandoned agricultural land has a statistically significant effect most bands. reflectance lands with deciduous and coniferous species is significantly different mixed forests does not differ fro...
Agriculture terraces constitute a significant element of the Mediterranean landscape, enabling crop production on steep slopes while protecting land from desertification. Despite their ecological and historical value, terrace cultivation is threatened by climate change leading to abandonment further marginalization arable imposing serious environmental community hazards. Re-cultivation terraced...
In the context of increased pressures on land for food and non-food production, it is relevant to understand better, which resources have become unused abandoned where these lands are. Data are what their extend not collected in regular statistics. this paper, we present an approach detect signs abandonment cropping using radar coherence data. The methodology was tested Spanish regions Albacete...
The geochemistry of rare earth element (REE) variations in acid waters is being studied as part of the U. S. Geological Survey Abandoned Mine Lands Initiative in two pilot watersheds, upper Animas, Colorado and Boulder, Montana. The following objectives are under investigation: (1) comparison of acid mine waters and naturally acidic springs, (2) determination of whether the dominant control on ...
