The article analyzes soil organic carbon (SOC) content of in Poland from 2015 to 2021. The research aims to determine SOC levels and their dependence on soil agronomic categories and drought intensity. Soil samples from 1011 farms across 8 Polish voivodships were collected for analysis, all from the same agricultural plots. SOC determination was conducted using the Tiurin method. The results indicate a low SOC content nationwide (0.85- 2.35%). Heavy soils exhibited higher SOC accumulation compared to light soils. Moreover, significant drought impact led to decreased SOC content in affected regions. Scientific evidence underscores a declining trend in organic carbon stock within agricultural soils, attributed to natural soil changes and unsustainable management practices. This decline is concerning given the crucial role of SOC in soil health, quality, and crop productivity. Therefore, it is imperative to monitor and address areas with low SOC levels to enhance SOC abundance. Furthermore, when used as a whole-cell biocatalyst in a low-cost upflow MFC, the Morganella morganii-rich SF11 consortium demonstrated the highest voltage and power density of 964.93±1.86 mV and 0.56±0.00 W/m3, respectively. These results suggest that the SF11 bacterial consortium has the potential for use in ceramic separator MFCs for the removal of penicillin and electricity generation.

W artykule dokonano analizy zawartości węgla organicznego w glebie (SOC) w Polsce w latach 2015 - 2021. Celem badań było określenie poziomu SOC oraz określenie jego zależności od kategorii agronomicznej gleby, odczynu i zawartości wody w glebie. intensywność suszy w glebie. Dane do analizy zawartości SOC uzyskano poprzez pobranie i analizę prób glebowych z 1011 gospodarstw zlokalizowanych na terenie całej Polski w 8 województwach Polski. Próbki gleby do badań pobierano co roku z tych samych powierzchni rolniczych. Oznaczenie SOC przeprowadzono metodą Tiurina. Wyniki testów wykazały niską zawartość SOC w całym kraju (0,85-2,35%). Lepsza. Większą kumulację zawartości SOC stwierdzono na glebach ciężkich w porównaniu z glebami lekkimi. Stwierdzono duży wpływ suszy na spadek zawartości SOC w rejonach jej występowania. Dowody naukowe wskazują, że zasoby węgla organicznego w górnych warstwach gleb rolniczych są niskie i nadal maleją w wyniku naturalnych zmian w glebie i niezrównoważonej gospodarki. Z danych naukowych wynika, że zasoby węgla organicznego w górnych warstwach gleb rolniczych zmniejszają się. Jest to szczególnie niepokojące, ponieważ zasoby SOC są ważnym czynnikiem wpływającym na zdrowie i jakość gleby, a tym samym na wydajność upraw. Z tego powodu bardzo ważne jest monitorowanie i identyfikowanie obszarów o niskim poziomie SOC oraz podejmowanie działań w celu poprawy obfitości SOC

Peatland rehabilitation is an urgent need in order to minimize the effects of peat degradation and to support climate change mitigation. However, the rehabilitation of degraded peatlands still faces many obstacles. This study aimed to study the agroforestry system on peatlands applied by traditional communities as an effort to discover a peatland rehabilitation strategy. This research was conducted in the Pilang, Tanjung Taruna, and Kalampangan villages from February to August 2019. The data in this study were obtained through field observations, interviews with the community, and Focus Group Discussion. The data was then synthesized using descriptive statistics. The results of data analysis showed that in the study area, six types of agroforestry systems were found. Communities develop different agroforestry systems at various types of peat depths. Farmers develop vegetable and fruit-based agroforestry on shallow peat, rubber-based agroforestry, annual crops and fruit on medium peat, fruit and rubber forestry plants on deep peat. Most farmers planted endemic species including Rubber (Havea braziliensis), Galam (Melaleuca leucadendra) and Gerunggang (Cratoxylum arborescens). The results of this study can be adopted as a peatland rehabilitation strategy since they are in accordance with the socio-culture of the local community and capable to accommodate economic and conservation interests.

The architectural form of buildings is determined by many factors, one of the most important is construction technology. It remains in a close and inseparable relationship with architectural design. Contemporary technologies in construction are constantly subject to improvements, streamlining, changes aimed at increasing all kinds of efficiency (cost, thermal efficiency, labor input, etc.). One of today's widely discussed determinants of changes in the way buildings are designed and constructed is environmental issue. An awareness of environmental degradation and climate change and their consequences prompts the search for increasingly sustainable solutions. This paper summarizes the research on prefabricated solutions and their implementation, especially in single-family residential architecture. This article presents pre-design, design, and post-design experiences related to planning and realization of single-family houses with prefabricated wall technology made of light expanded clay concrete. The authors implemented comparative qualitative and quantitative research through case studies, the method also uses experiences from their own research by design practice. The advantages and disadvantages of prefabrication in the selected technology are presented. The authors attempt to answer the question of whether the individual architectural design approach is reflected in the relevant environmental considerations, including, first, those related to the mitigation of climate change and adaptation to its consequences, and to what extent the discussed technology fits into the assumptions of climate and environmentally responsible design.

Peat forest plays a principal role in climate change mitigation in Indonesia. Considering the potential releases of GHGs from a forest fire and degraded peatland, it is important to conserve peatland forests. Besides being essential for ecological balancing, the role of peatland forest expands to the economic and social aspects. The purpose of this research was to calculate CO2 emissions that can be avoided by the community-based fire prevention and rewetting program. This research utilized spatial analysis to calculated avoided CO2 emissions in six villages in Central Kalimantan. Data and information for the calculation were generated from field observations, interviews, and desk study. Spatial analysis using Arc GIS 10.5 was applied to compute the incombustible areas. The result from the analysis found that fire prevention and rewetting programs managed to prevent approximately 1 million Mg C or equivalent to 3.7 million CO2. The program managed to prevent emission from the vulnerable area including swamp shrubs, plantations and dry land agriculture. The finding of this study suggests that community-based fire prevention and peatland rewetting programs could become a strategic program in climate change mitigation in Indonesia.

The present research deals with carbon sequestration, as an important process for mitigating the effects of climate change. The investigation focuses on a 30-year period and it covers only aboveground biomass that builds up from natural forest regrowth, excluding any plantation techniques. Potential carbon sequestration rate from natural forest regrowth in Godech Municipality was measured in Mg C ha⁻¹ yr⁻¹ and the resolution of the map was 1x1 km. The results of the study display that carbon accumulation values in the researched area were consistent with those that were expected in the largest parts of Bulgaria. The biggest share of Godech Municipality falls within the range of 0.82 – 0.96 Mg C ha⁻¹ yr⁻¹ with restricted areas around the villages of Barlya, Smolcha, Gubesh, Murgash and Varbnitsa that may accumulate between 0.96 – 1.11 Mg C ha⁻¹ yr⁻¹. In conclusion, carbon accumulation only from natural forest regrowth provides representative information, however it would have been better if different plantation techniques were regarded as well. The successful results of the investigation should encourage other studies of this type in the neighbouring municipalities.

Purpose: To analyse the potential of various scenarios for reduction of carbon footprint of iron and steel sector and to reveal plausible pathways for modernisation. Design/methodology/approach: Several scenarios have been developed in order to assess the dynamics and extent of decarbonisation required to meet the global climate change mitigation target. This includes deployment of the best available technologies, increased share of secondary steel production route and deployment of innovative ironmaking technologies with various decarbonisation extent achieved in a variable timeframe. Findings: The window of opportunities to ensure compliance of steel sector development with climate goal still exists though shrinks. Modernisation shall include global deployment of best available technologies, increased share of secondary steel production and rapid deployment of innovative technologies including carbon capture and storage. Delayed modernisation will require much deeper decarbonisation, which will increase the total cost of mitigation. International policies shall be put in place to ensure availability of funding and to assist technology transfer. Short term transition strategies shall be employed as soon as possible for bridging long term climate change mitigation strategies and current state of the iron and steel industry worldwide. Research limitations/implications: Methodology applied takes into account the best available technologies and some novel ironmaking methods with the potential for commercialisation during the next decade; however, it is implied that the radically innovative iron- and steelmaking technologies with near-zero CO2 emissions will not be mature enough to deliver tangible impact on the sector’s carbon footprint before 2050. Practical implications: Obtained results can be helpful for definition of the modernisation strategies (both state-level and corporate) for the iron and steel industry. Originality/value: Dynamics and extent of decarbonisation required to meet global climate change mitigation targets have been revealed and the results can be valuable for assessment of the consistency of sectoral climate strategies with global targets.
