Surface displacement caused by natural and anthropogenic activities poses a significant risk to subsurface pipelines, particularly in areas experiencing subsidence. Stress and strain induced by deformation can lead to pipeline buckling and potential vulnerability. This study applies a multidisciplinary approach integrating interferometric synthetic aperture radar (InSAR) deformation analysis, well data, and geological context to assess the risk to oil and gas pipelines in Iran’s Qazvin plain. The focus is on evaluating the impact of an unconfined aquifer, which has a lower risk of subsidence compared to a confined aquifer, on pipeline infrastructure. We analyzed multitemporal Sentinel-1 data collected between 2014 and 2021. Our findings reveal that 2,400 km 2 of the study area is experiencing subsidence with vertical rates reaching up to 14 cm/year with an average S k {S}_{{\rm{k}}} , or skeletal storage value of 0.04. We explore the reasons for this unexpectedly high subsidence, finding that compressible unconfined aquifers with historically low water levels are also at risk for significant inelastic, or permanent, subsidence. We also evaluate pipeline profiles, which show spatial subsidence, much higher than typically seen in unconfined aquifers, with variations of up to 1 m, indicating long-term risks to the infrastructure. This study demonstrates the potential of InSAR techniques in assessing the risk to critical infrastructure, such as oil and gas pipelines, in regions with land deformation due to groundwater withdrawal. Our approach underscores the importance of continuous monitoring and offers valuable insights for addressing the challenges posed by subsidence on pipeline infrastructure.

Biodiversity in human-dominated landscapes is declining, but evidence-based conservation targets to guide international policies for such landscapes are lacking. We present a framework for informing habitat conservation policies based on the enhancement of habitat quantity and quality and define thresholds of habitat quantity at which it becomes effective to also prioritize habitat quality. We applied this framework to insect pollinators, an important part of agroecosystem biodiversity, by synthesizing 59 studies from 19 countries. Given low habitat quality, hoverflies had the lowest threshold at 6% semi-natural habitat cover, followed by solitary bees (16%), bumble bees (18%), and butterflies (37%). These figures represent minimum habitat thresholds in agricultural landscapes, but when habitat quantity is restricted, marked increases in quality are required to reach similar outcomes.

Despite the increasing popularity of wind power farms this kind of energy production has been contested, citing cultural, economic, and sometimes even environmental reasons – especially when such power farms are built in areas of significant environmental value and status, as is the case of several areas in the High North. One way to explore this conflict is through understanding the effects of such projects on local ecosystem services (e/s) – i.e., the direct and indirect benefits that ecosystems provide to support and sustain human livelihoods. This article discusses the perceived consequences on e/s after the development of a wind power farm in a Northern Norwegian context (High North), at the area of Kvitfjell/Raudfjell on the island of Kvaløya. Following a mixed-methods approach, combining exploratory data analysis (EDA) with thematic and sentiment analysis, the article presents a recent survey among various actors and stakeholders in the examined area to explore how they perceived the effects of the newly constructed wind power farm on e/s. Our results illustrate that a significant portion of the respondents maintained a critical and even apprehensive attitude on the wind farm development, although some positive economic impacts to the local community were also acknowledged.

Det er gjennomført en estimering av jordbrukets behov for nitrogen og fosfor og en kartlegging av de organiske gjødselressursene i Vestfold fylke. Det er valgt ut gjødselkildene husdyrgjødsel, biorest og slam, og estimert det totale innholdet av nitrogen og fosfor i disse kildene. En slik oversikt gir muligheter til å se på fordelingen av gjødselressursene innad i fylket, for derigjennom å kunne redusere utslipp til vann og vassdrag, samt redusere klimagassavtrykket og bidra til mer bærekraftig matproduksjon. I Vestfold fylke er det totale nitrogenbehovet for vekstene korn, potet, gras, grønnsaker, frukt, bær og oljevekster estimert til rundt 5 900 tonn per år. Bak dette tallet ligger det en rekke forutsetninger. Disse forutsetningene vil kunne endre seg betydelig ved endringer i arealfordeling av jordbruksvekstene og ved endringer i avlingsnivå. Mengden totalnitrogen i dagens produksjon av husdyrgjødsel, biorest og avløpsslam i fylket, er estimert til rundt 2 300 tonn per år. Av dette vil en gitt andel tapes til luft og vann gjennom uunngåelige tap siden det er organisk gjødsel. I tillegg vil ulik håndtering av gjødsla kunne forsterke tapene. Mengden plantetilgjengelig nitrogen vil derfor være lavere enn estimert totalnitrogen. Estimatene viser at landbruket i Vestfold har behov for minst 3 570 tonn mer nitrogen per år enn det som er tilgjengelig av organisk nitrogen i dag. Det totale fosforbehovet for vekstene korn, potet, gras, grønnsaker, frukt, bær og oljevekster er estimert til rundt 750 tonn per år for Vestfold fylke. Det er da ikke tatt hensyn til jordas P-AL-nivå. Hvis 25 % av jordbruksarealet har P-AL over 14, kan fosforbehovet reduseres til rundt 570 tonn per år. Hvis 50 % av jordbruksarealene har høyere P-AL enn 14, reduseres fosforbehovet ytterligere, til rundt 380 tonn per år. Mengden totalfosfor i husdyrgjødsel og biorest, og mengden plantetilgjengelig fosfor i avløpsslam er estimert til 308 tonn per år. Ved balansegjødsling med fosfor på alt jordbruksareal, dekkes ca. halvparten av fosforbehovet gjennom organisk gjødsel. Ved å ta hensyn til jordas P-AL-nivå, vil fosforbehovet reduseres, og nærme seg mengden fosfor som finnes i fylket i organiske kilder.

VKM has assessed the potential risk to Norwegian biodiversity associated with the import of the Turkestan cockroach, Periplaneta lateralis, as live food for hobby animals. Populations of the cockroach are nearly always found in or near buildings, and non-native populations have never been observed in natural environments. No previous observations of P. lateralis have been reported for Norway and it is very unlikely the species will be able to establish and spread into Norwegian nature due to the low winter temperatures and short summers. Furthermore, VKM find that there is low risk associated with the potential effects on biodiversity, if it against all odds, were to establish in Norway. Therefore, VKM concludes that there is low risk associated with import and keeping of P. lateralis in relation to its potential negative effect on Norwegian biodiversity.

To date, only adults of Zercon forsslundi have been known. According to the description of this species, it has been the first report of Zercon with clear differences in opisthonotal chaetotaxy between females and males, a unique character in the genus. At the same time, Z. forsslundi belongs to a unique group of Zercon species with dorsal setae J5 in females clearly longer than setae J1 – J4 , the latter ones being short and of similar length. Our description is the first-ever report on the full morphological ontogeny of Z. forsslundi , the mite species, the adult which is the most similar to the recently described Zercon hamaricus and to a lesser extent to Zercon polonicus . The morphological closeness of the above-mentioned species has been confirmed in immature stages. We also studied the geographic distribution of Z. forsslundi and its above-mentioned congeners with remarks on their evolutionary affinity on the background of dispersal abilities and faunal dispersal after the Last Glacial Maximum. We also report the occurrence of Z. forsslundi and Z. hamaricus in the Northern Norway for the first time. Ranges of Z. forsslundi and Z. hamaricus overlap in the area of N Norway. Also, the microenvironmental sympatry was confirmed for these taxa. We also proved the niche overlap of these two species, which is probably limited to the northern verge of Eurasia. Zercon polonicus , not present in the current Arctic fauna, probably is a post-glacial relict, inhabiting more southern mountainous areas of Europe (Carpathians and Alps).
