The default methods in the 2019 Refinement drastically reduce estimates of global carbon sinks of harvested wood products

Background The stock dynamics of harvested wood products (HWPs) are a relevant component of anthropogenic carbon cycles. Generally, HWP stock increases are treated as carbon removals from the atmosphere, while stock decreases are considered emissions. Among the different approaches suggested by the Intergovernmental Panel on Climate Change (IPCC) for accounting HWPs in national greenhouse gas inventories, the production approach has been established as the common approach under the Kyoto Protocol and Paris Agreement. However, the 24th session of the Conference of the Parties to the United Nations Framework Convention on Climate Change decided that alternative approaches can also be used. The IPCC has published guidelines for estimating HWP carbon stocks and default parameters for the various approaches in the 2006 Guidelines, 2013 Guidance, and 2019 Refinement. Although there are significant differences among the default methods in the three IPCC guidelines, no studies have systematically quantified or compared the results from the different guidelines on a global scale. This study quantifies the HWP stock dynamics and corresponding carbon removals/emissions under each approach based on the default methods presented in each guideline for 235 individual countries/regions. Results We identified relatively good consistency in carbon stocks/removals between the stock-change and the atmospheric flow approaches at a global level. Under both approaches, the methodological and parameter updates in the 2019 Refinement (e.g., considered HWPs, starting year for carbon stocks, and conversion factors) resulted in one-third reduction in carbon removals compared to the 2006 Guidelines. The production approach leads to a systematic underestimation of global carbon stocks and removals because it confines accounting to products derived from domestic harvests and uses the share of domestic feedstock for accounting. The 2013 Guidance and the 2019 Refinement reduce the estimated global carbon removals under the production approach by 15% and 45% (2018), respectively, compared to the 2006 Guidelines. Conclusions Gradual refinements in the IPCC default methods have a considerably higher impact on global estimates of HWP carbon stocks and removals than the differences in accounting approaches. The methodological improvements in the 2019 Refinement halve the global HWP carbon removals estimated in the former version, the 2006 Guidelines.

Defining research priorities for youth public mental health: reflections on a co-production approach to transdisciplinary working

Background With most mental health problems established during childhood/adolescence, young people must be a key focus of public mental health (PMH) approaches. Despite the range of factors known to influence mental health, evidence for effective interventions is lacking for this age group. This study aimed to define priorities for future intervention-focussed research to support youth PMH by engaging with transdisciplinary stakeholder groups. Methods Our co-production approach involved priority-setting workshops with young people, researchers, practitioners and policymakers. Each workshop focussed on three thematic areas: social connections and relationships; schools and other education settings; key groups at greater risk of mental ill-health, specifically LGBTQ+ and care-experienced young people. Workshop outputs were synthesised to define research priorities. Results Ten priorities for youth PMH research were defined, covering the following areas: building supportive relationships; whole system approaches; social media; support at times of transition; improving links between different services; development and training for those who support young people; staff mental health; engaging with families; awareness of and access to services; out of school and community settings. Conclusions These research priorities can inform future intervention-development to support youth PMH. Our transdisciplinary approach means the identified research priorities are more likely to be relevant to young people’s experiences and needs, and to fit with the needs of those working in practice and policy to support young people.

Analysis of software solutions for creating models by a generative design approach

With the constant development of new technologies and designs, the idea of a generative design approach arose. Generative design allows to create an infinite number of new designs in a relatively short time without the constraints associated with the imagination of the designer. Designs created by a generative design approach create optimized products that meet the specific needs of their end users. The parts created in this way are often lighter, stronger and less expensive in terms of their subsequent production. Generative design software applications are often more intuitive to work with than traditional CAD systems, and no additional knowledge associated with operating the software is required. The main goal of generative design is to save time in the design process, save material by creating optimal structures, and thus save money by developing cost-effective products. The product software only adds material where it is needed, which is typical of the additive production of organic shapes and forms. The product created in this way is more efficient for production compared to the traditional design and production approach. The article points out the current state of development of this rapidly expanding design technology with a description of software solutions used for the implementation of a generative design approach on illustrative examples of created design products.

“APPROPRIATION” AS A FORM OF PRODUCTION IN POSTMODERN ART: THE YASUMASA MORIMURA CASE

Although "appropriation", in other words "appropriation/adaptation", is a production approach that originates the productions of modern period artists, it has been one of the artistic orientations that form the roof of the Postmodern artistic pluralist structure, which basically has an eclectic body. Artists, who adopt and defend this mode of production, have reinterpreted and circulated existing or previously produced works/images/forms, contrary to the new production approach. At the same time, these artists, who consciously use the symbolic importance of the works they appropriate, while creating the cultural framework of their own production, seek a construction of meaning based on concepts such as reference, citation, irony, parody and incongruity, as well as a structure that tries to draw attention to the richness of meaning in contemporary art. have been placed on their agenda. This concept, which has developed an attitude against the notion of "originality" of modernism, has developed new arguments on the concepts of gender and racial discrimination, social language and discourse, identity, culture and representation, especially after the 1980s, examining the social codes that took shape through certain power relations. It has been shaped even more by the production practices of the artists. In this study, the "appropriation" approach, which is the source of many productions of postmodern art, is mentioned and a quick introduction to the sanctuary of art in the name of the interpretation and analysis of this concept and bringing the "authenticity/originality" discussions in art to the agenda again; The works of Japanese artist Yasumasa Morimura, who revived the masterpieces of art history and popular culture icons in his own body, in order to find himself again in other bodies, to experience and learn, are mentioned. Keywords: Postmodern art, appropriation, reproduction, Yasumasa Morimura

Bio-economic production potentiality of Solanum lycopersicum under smart agroforestry practice

Food security and maximum land use system are the priorities of crop production technique in the present global food growing environment. The tomato-Albizia lebbck agroforestry is an effective smart production approach. The aim of this research is to find out the appropriate combination of organic mulch leads the tomato Albizia lebbck agroforestry production as compared to sole cropping technique for growth, yield, and quality that brings health hygiene for fresh and cooked consumption. The experiment was laid out following two factors split plot design with three (3) replications. Tomato in open field (T0) and tomato under Albizia lebbeck woodlot agroforestry system (T1) were arranged in main plots. Conversely, the usage of organic mulches was set in sub-plots viz. M0= No mulch, M1= Ash mulch, M2= Saw dust mulch, and M3= Water hyacinth mulch. The results indicated the highest yield (32.65 t/ha) was found in water hyacinth mulch (M3) and the lowest yield (21.37 t/ha) was detected in M0 without mulch (control). The treatment M3 (water hyacinth mulch) gave the maximum sugar-acid ratio (12.04%) and minimum sugar-acid ratio (9.42%) was found in control (no mulch). Furthermore, the result showed the production potentiality was the highest yield (29.41 t ha-1) was found in tomato- Albizia lebbeck agroforestry (T1) and the lowest yield (25.95 t ha-1) was recorded in sole cropping of tomato (T0). The maximum sugar-acid ratio (11.37%) was found in tomato- Albizia lebbeck agroforestry (T1) and the minimum sugar-acid ratio (10.31%) was found in sole cropping of tomato (T0). On the other, the combined effect tomato- Albizia lebbeck agroforestry with water hyacinth mulch gave the highest yield (35.01 while, the lowest yield (22.47 t ha-1) was observed in sole cropping of tomato without mulch. The research finding also revealed the maximum benefit-cost ratio (4.94) was found from the tomato- Albizia lebbeck agroforestry which was 20 % higher than tomato was grown in sole cropping. Finally, the tomato- Albizia lebbeck agroforestry production in association with organic hyacinth mulch can be an effective production approach for maximum return in terms of yield, quality and money.
