In Chapter 2, the authors focus on the importance of precision-based soil and nutrient management practices tested on rice farms in the eastern part of India and the potential for reducing GHG emissions. This is highly relevant for countries such as India, Vietnam, Myanmar, Bangladesh, and Thailand with large areas under rice production, where the use of excess amounts of fertilizer and chemicals, especially nitrogen fertilizer, is a serious problem for the environment and health of people. The chapter shows the importance and benefits from the use of tools ranging from the simple leaf colour chart to innovative digital tools and their relevance to improve nutrient use efficiency. The chapter towards the end provides guidelines/models and policy recommendations for upscaling precision soil and nutrient management in rice systems and other related food crops.

Background Since the late 1800s, an unknown number of common pheasants and grey partridges from captive bred stocks have been released in Norwegian nature. The birds are released to be used for training of pointing dogs. The import, keeping and release of gamebirds, as well as the management of release sites, have been largely unregulated. The consequences to biodiversity, animal health and welfare have not been investigated. The Norwegian Environment Agency (NEA) and the Norwegian Food Safety Authority (NFSA) have jointly requested the Norwegian Scientific Committee for Food and Environment (VKM) for a scientific opinion on the release of common pheasants and grey partridges for pointing dog training regarding consequences for biodiversity, animal welfare of the released birds and health of the released birds as well as wild birds to which pathogens may be transmitted. VKM was further asked to suggest risk reducing measures for biodiversity and animal welfare. Methods VKM established a project group with expertise within avian ecology, landscape ecology, population biology, wildlife veterinary medicine and animal welfare. The group conducted systematic literature searches, scrutinized the resulting literature, and supplemented by other relevant articles and reports. In the absence of Norwegian studies, VKM used literature from other countries where common pheasants and grey partridges (and in some cases other gamebirds), are released, as references. The project group applied observation data of common pheasants and grey partridges in Norway for the period 2000-2022, presented by the Norwegian Biodiversity Information Centre (NBIC). In the assessments, VKM assumed that the release of birds will be in the same order of magnitude as in previous years (a few thousand birds annually on a national level). The number of release sites and the density of released birds per site are unknown. Increasing the number and density of birds would also increase the probability of negative effects and the severity of the consequences. VKM assessed the impacts of released common pheasants and grey partridges on competition, predation, hybridization, transmission of disease, herbivory and indirect impacts through interactions with other species (predator abundance and pathogen-mediated competition). VKM also assessed the impact on biodiversity in a 50-year perspective. Furthermore, VKM discusses how the birds’ welfare might be impacted by rearing, transport, release and exposure to pointing dogs. Finally, VKM provides a list of relevant diseases and assessed their potential impact on animal health during transport, rearing and release. Results and conclusions VKMs assessment show that there are several risks to biodiversity, animal health, and animal welfare from the release of captive bred common pheasants and grey partridges in Norway. The risk of increased competition for food, particularly in winter, with birds with similar niches as common pheasants and grey partridges, is low on a national scale and moderat on a local scale. This is particularly so for yellowhammer, Emberiza citronella, a species categorized as vulnerable on the national red list due to its progressive population decline caused by reduced availability of food during winter. There is a moderate risk for predation on invertebrates and negative impacts on flora. Indirectly, activities connected to the release of birds may lead to moderate risks of altered predator abundance and disease-mediated competition. VKM concludes that the ecological impacts will be more severe for redlisted species present within the release areas for common pheasants and grey partridges. Repeated release of common pheasants and grey partridges can lead to high risk of disease transmission to wild birds. .............

Wood resources have been essential for human welfare throughout history. Also nowadays, the volume of growing stock (GS) is considered one of the most important forest attributes monitored by National Forest Inventories (NFIs) to inform policy decisions and forest management planning. The origins of forest inventories closely relate to times of early wood shortage in Europe causing the need to explore and plan the utilisation of GS in the catchment areas of mines, saltworks and settlements. Over time, forest surveys became more detailed and their scope turned to larger areas, although they were still conceived as stand-wise inventories. In the 1920s, the first sample-based NFIs were introduced in the northern European countries. Since the earliest beginnings, GS monitoring approaches have considerably evolved. Current NFI methods differ due to country-specific conditions, inventory traditions, and information needs. Consequently, GS estimates were lacking international comparability and were therefore subject to recent harmonisation efforts to meet the increasing demand for consistent forest resource information at European level. As primary large-area monitoring programmes in most European countries, NFIs assess a multitude of variables, describing various aspects of sustainable forest management, including for example wood supply, carbon sequestration, and biodiversity. Many of these contemporary subject matters involve considerations about GS and its changes, at different geographic levels and time frames from past to future developments according to scenario simulations. Due to its historical, continued and currently increasing importance, we provide an up-to-date review focussing on large-area GS monitoring where we i) describe the origins and historical development of European NFIs, ii) address the terminology and present GS definitions of NFIs, iii) summarise the current methods of 23 European NFIs including sampling methods, tree measurements, volume models, estimators, uncertainty components, and the use of air- and space-borne data sources, iv) present the recent progress in NFI harmonisation in Europe, and v) provide an outlook under changing climate and forest-based bioeconomy objectives.

This chapter provides a comprehensive review of various integrated pest management (IPM) measures in combination with bio-based interventions, and physical and cultural practices that provide proven benefits for biodiversity, ecosystem services, and climate mitigation. The chapter illustrates the importance of digital technologies that represent another line of promising solutions to counter the environmental costs of crop production systems and enhance climate neutrality. Such solutions include precision farming with threshold-based and spatially targeted application of pesticides. A key factor to bridge gaps between scientific knowledge and practical implementation of IPM measures is the continuous involvement, training, and co-design of solutions with farmers’ communities and other stakeholders.

Although it is well known that insects are sensitive to temperature, how they will be affected by ongoing global warming remains uncertain because these responses are multifaceted and ecologically complex. We reviewed the effects of climate warming on 31 globally important phytophagous insect pests to determine whether general trends in their responses to warming were detectable. We included four response categories (range expansion, life history, population dynamics, and trophic interactions) in this assessment (Figure 1). For the majority of these species, we identified at least one response to warming that affects the severity of the threat they pose as pests. Among these insect species, 41% showed responses expected to lead to increased pest damage, whereas only 4% exhibited responses consistent with reduced effects; notably, most of these species (55%) demonstrated mixed responses. This means that the severity of a given insect pest may both increase and decrease with ongoing climate warming. Overall, our analysis indicated that anticipating the effects of climate warming on phytophagous insect pests is far from straightforward. Rather, efforts to mitigate the undesirable effects of warming on insect pests must include a better understanding of how individual species will respond, and the complex ecological mechanisms underlying their responses. Although not the focus of our review, the main conclusions we reach also should hold true for biological control agents and there is indeed evidence for phenological mismatch and other climate-change-related effects on biological control of varying magnitude among systems. At least some natural control agents seem to respond more positively to climate warming than their herbivore prey, and as such, one might expect better biological control in certain systems. One potential reason for these differences is that while both control agents and herbivores are affected physiologically by changing climate drivers, by for instance increasing development rate, the control agents in addition are affected behaviourally and, for instance, can increase foraging or searching rate. In addition, and specifically in relation to biological control, it is often crucial to achieve high synchronization between control agent and prey, which can be complicated by different response rates to winter temperature. This is something that has been observed with the chestnut gall wasp Dryocosmus kuriphilus (Hymenoptera: Cynipidae) and its parasitoid Proceedings of ISBCA 6 – D.C. Weber, T.D. Gariepy, and W.R. Morrison III, eds. (2022) page 3.19 Torymus sinensis (Hymenoptera: Torymidae) over the last years, as the gall wasp depends largely on the budbreak of the host plant while the parasitoid relies mainly on the air temperature for spring emergence. Figure 1. Four major categories of responses to climate warming. (a) Range changes include range expansions or shifts (latitudinal and/or altitudinal). (b) Life-history changes primarily consist of alterations to biological timing events or the number of annual generations. (c) Population dynamics reflect population size, and damage is expected to increase whenever temperature limits performance, but if threshold temperatures are reached, control and related feedback mechanisms may be triggered. Tpresent reflects current temperatures over a time period (e.g., a year or a day), whereas Tfuture reflects future temperatures over the same period. (d) Trophic interactions reflect temperature responses of organisms and trophic groups (plants = dashed green line, herbivores = solid red line, predators = dashed blue line). Because vital rates (i.e. rates of important life-history traits, such as growth, dispersal, and reproduction) may vary, climate warming could strongly affect trophic relationships. This is of direct consequence for the planning and efficiency of biological control programs.

Statens vegvesen bygger ny vei, E18 Vestkorridoren, mellom Lysaker og Ramstadsletta med nytt kollektivfelt, ny sykkelveg, ny vegforbindelse fra Strand til Fornebu og ny fylkesvei mellom Gjønnes og E18. Forberedende anleggsarbeider startet opp i november 2020 med entreprise E108 ved Høvik og deretter juni 2021 med entreprise E101 Fornebukrysset Strand. E108 har ikke hatt utslipp til kommunalt overvannsnett eller resipient. E101 startet utslippene til kommunalt nett og resipienter i november 2021. Etter oppdrag fra Statens vegvesen har NIBIO med samarbeidspartner Norconsult utført miljøovervåking av vannforekomster som har blitt berørt av anleggsarbeider i forbindelse med byggeprosessen i 2021. Undersøkelsene har omfattet resipienter nært der det pågår anleggsarbeid, både i ferskvann (Stabekken og Tjernsmyr) og i Bærumsbassenget med de marine resipientene Holtekilen og Solvikbukta, samt stikkprøvetaking av renset anleggsvann. Miljøovervåkingen har hatt som mål å kartlegge økologisk og kjemisk tilstand gjennom undersøkelse av biologiske kvalitetsparametere og vannkjemi og eventuelt å avdekke negative konsekvenser av anleggsarbeid på resipientene. I Holtekilen og Solviksbukta har Norconsult utført undersøkelser om tilstedeværelsen av ålegrassenger. En stasjon i Bærumsbassenget er også omtalt, der NIVA på oppdrag for Fagrådet for vann- & avløpteknisk samarbeid i Indre Oslofjord utfører pågående overvåking. De undersøkte vannforekomstene ligger i et urbant miljø og er påvirket av avrenning fra veger og tette flater samt andre menneskeskapte utslipp/avrenning. Næringsstoffer ble påvist i høye konsentrasjoner i ferskvannsforekomstene, tilsvarende klassifisering «Svært dårlig tilstand». Sink og arsen ble påvist i forhøyede konsentrasjoner. Det ble også påvist PAH-forbindelser i ferskvannsresipientene. Ferskvannsresipientene som ble prøvetatt i 2021 har ikke vært påvirket av anleggsvann (utslippene til disse områdene var ikke startet), så forurensingene antas å stamme fra andre kilder. Undersøkelsen av vannkvalitet i de marine vannforekomstene viste varierende konsentrasjoner av næringsstoffer, fra «Svært god» tilstand for nitrat til «Svært dårlig» for total nitrogen. Siktedypet varierte under sesongen, men havnet i tilstandsklassen «God». Alle de marine vannprøvene viste en forhøyet konsentrasjon av arsen tilsvarende «Moderat» tilstand og det ble påvist forhøyede konsentrasjoner av sink. I vannfasen ble det ikke påvist forhøyede konsentrasjoner av noen organiske miljøgifter. For både Holtekilen og Solviksbukta ble det påvist ålegrasenger, med både ålegras og havgras til stede. Disse ble klassifisert til å være i «God tilstand». Det er foreløpig lite som indikerer at anleggsarbeidene har hatt påvirkning på resipientene i Bærumsbassenget. Stikkprøvetaking av renset anleggsvann er tatt fra to av entreprenøren på E101 sine renseanlegg; renseanlegget på Grendehustomta og renseanlegget i Eilif Dues veg. Det ble funnet relativt lave verdier av tungmetaller i renset anleggsvann fra Grendehustomta. pH og konsentrasjoner av suspendert stoff lå godt innenfor utslippskravet til Statsforvalteren. Det ble ikke påvist oljeforbindelser i vannprøven. Det var høye verdier nitrogen i vannprøven med en total nitrogen-konsentrasjon på 1500 μg/l. Også nitrat- og ammoniums-verdiene var høye (hhv. 440 og 330 μg/L). Høye nitrogenkonsentrasjoner kan forekomme i anleggsvann når det benyttes sprengstoff på anlegget. Renseanlegget på byggeplassen ved Eilif Duesvei sender renset avløpsvann til spillvannsnettet og videre til det kommunale renseanlegget VEAS. Ingen av grenseverdiene som er gitt av Bærum kommune ble overskredet. Det ble imidlertid påvist høye ammoniums-verdier, noe som gjerne forbindes med sprengningsarbeider på anleggsområdet.

Digestate, a by-product from anaerobic digestion of organic materials such as animal manure, is considered a suitable plant fertilizer. However, due to its bulkiness and low economic value, it is costly to transport over long distances and store for long periods. Refinement processes to valorize digestate and facilitate its handling as a fertilizer include precipitation of phosphorus-rich mineral compounds, such as struvite and calcium phosphates, membrane filtration methods that concentrate plant nutrients in organic products, and carbonization processes. However, phosphorus retention efficiency in output products from these processes can vary considerably depending on technological settings and characteristics of the digestate feedstock. The effects of phosphorus in plant fertilizers (including those analogous or comparable to refined digestate products) on agronomic productivity have been evaluated in multiple experiments. In this review, we synthesized knowledge about different refinement methods for manure-based digestate as a means to produce phosphorus fertilizers, thereby providing the potential to increase phosphorus retention in the food production chain, by combining information about phosphorus flows in digestate refinement studies and agronomic fertilizer studies. It was also sought to identify the range, uncertainty, and potential retention efficiency by agricultural crops of the original phosphorus amount in manure-based digestate. Refinement chains with solid/wet phase separation followed by struvite or calcium phosphate precipitation or membrane filtration of the wet phase and carbonization treatments of the solid phase were included. Several methods with high potential to extract phosphorus from manure-based wet phase digestate in such a way that it could be used as an efficient plant fertilizer were identified, with struvite precipitation being the most promising method. Synthesis of results from digestate refinement studies and agronomic fertilizer experiments did not support the hypothesis that solid/wet separation followed by struvite precipitation, or any other refinement combination, results in higher phosphorus retention than found for unrefined digestate. Further studies are needed on the use of the phosphorus in the solid phase digestate, primarily on phosphorus-rich soils representative of animal-dense regions, to increase understanding of the role of digestate refinement (particularly struvite precipitation) in phosphorus recycling in agricultural systems.

Commercial mushroom production is based on composted locally available agro-industrial wastes rich in carbon and nitrogen such as wheat straw supplemented with chicken manure. Either component can be replaced by other kinds of grain straw: barley, oat, or a mixture of different straw types and combined with diary manure—food waste digestate after anaerobic biogas digestion. Original, unseparated liquid digestate is nutritious, rich in nitrogen and organic matter. This research aimed to investigate the effect of digestate and different straw ratios on the composting process and productivity and their consequent effect on mushroom cultivation parameters of Agaricus subrufescens. All investigated experimental mushroom compost (EMC) types worked well during the composting process, reaching the desired moisture of 65–75%, N content of 1.43–1.93%, and a C/N ratio ranging from 21.5 to 29.1, supporting growth of mycelium and producing mushrooms. Supplementation with barley straw resulted in better EMC structure with the highest yield and biological efficiency (BE) (157.9 g kg−1; 64%), whereas oat addition gave the lowest yield and BE (88.6 g kg−1 and 38%). Precociousness (yield at mid-cycle of the crop development) was higher for oat substrates (68.9%), while earliness (days to harvest from casing) was lower for barley EMC.

Lumpfish is now the single most important cleaner fish species to date and there is an extensive lumpfish translocation along the Norwegian coast. A reliable baseline information about the population genetic structure of lumpfish is a prerequisite for an optimal managing of the species to minimize possible genetic translocation and avoid possible hybridisation and introgression with local populations. The current study is a follow up of the study of Jónsdóttir et al. (2018) using expressed sequence tag-short tandem repeats (EST-STRs) markers. Samples (N = 291) were analysed from six sample locations along the Norwegian coastline from south to north, with additional 18 samples of first-generation (from wild fish) reared fish from a fish farm outside Tromsø (North Norway). Present findings show a lack of population differentiation among lumpfish sampling population along the Norwegian coast using EST-STRs, which is in accordance with the findings of Jónsdóttir et al. (2018) where genomic STRs (g-STRs) were analysed. Present findings indicate that should translocated lumpfish escape from salmon sea pens in Norway, this will probably have little impact on the genetic composition of the local lumpfish population.
