Cím:Monitoring the Spatiotemporal Evolution of the Green Dam in Djelfa Province, Algeria / Ramzi Benhizia, Yacine Kouba, György Szabó, Gábor Négyesi, Behnam Ata

Megjegyzések:Green walls and green dams are increasingly being considered as part of many national and international desertification initiatives. This paper studies the spatiotemporal evolution of the green dam in the Moudjbara region (Djelfa Province, Algeria), from 1972 to 2019, by using Landsat imagery, Land Change Modeler, and OpenLand package. The future evolution of pine plantations, for the year 2029, was also forecasted, based on an anthropogenic scenario (i.e., anthropogenic pressure is the main driver of the green dam destruction). Our findings revealed that the green dam project was successful for a few years, but, after that, pine plantations deteriorated significantly, due to forest harvesting, livestock overgrazing, and the proliferation of the pine caterpillar processionary, which destroyed most of the reforestation. Land change modeler predicted a huge degradation of pine plantations for the year 2029, and if the deforestation continues at the same rate, the green dam in the Moudjbara region will disappear during the next few decades. Being aware of this threat, the Algerian authorities are now planning to reforest more than 1.2 million ha under the latest rural renewal policy, by introducing new principles related to sustainable development, fighting desertification, and climate change adaptation. We strongly recommend moving away from the singular tree planting focus, to diversifying desertification control methods.

Cím:Land Use Changes in Peri-Urban Open Spaces of Small Towns in Eastern Hungary / Péter Csorba, Krisztina Bánóczki, Zoltán Túri
Dátum:2022
ISSN:2071-1050
Megjegyzések:Changes in land use were studied in 2 km wide peri-urban open spaces of seven small Hungarian towns as part of a RENATUR Interreg Europe (2019-2023) project. The aim of the project is to present best practices related to the sustainable and wise use of the peri-urban open spaces of small European towns. The rate and tendencies of conversion from one land use type to another were evaluated on the basis of a comparison of Corine Land Cover and Land Cover Change databases from 1990, 2000 and 2018. Land use changes in the study areas in different time periods were studied for which the Corine categories were aggregated. Subsequently, there were field verification surveys carried out between March and June of 2021. Most significant changes?due to the significant increase of built-up areas?were found in the case of the towns that were developed to form the suburbs of Debrecen, the core settlement of their region with a population of 200,000. In the case of settlements further away from the major city, the population is either stagnating or decreasing, and the size of built-up areas hardly increases. In the case of cities that are surrounded by high-quality chernozem soils with profitable agriculture, large-scale arable lands have become dominant in the border zones of the settlements, as the spatial extent of gardens, orchards and grasslands has decreased. Highly diverse and mosaic land use (dominated by small plots) is not characteristic anywhere.

Cím:Effects of Using Green Concrete Materials on the CO2 Emissions of the Residential Building Sector in Egypt / Heba Marey, Gábor Kozma, György Szabó
Dátum:2022
ISSN:2071-1050
Megjegyzések:Increasing the rate of construction material consumption has caused significant environmental problems in recent decades, especially the production of ordinary Portland cement (OPC), which has been associated with 8% of the world's human CO2 emissions and is considered the leading binder of concrete. This study aims to investigate the effects of substituting conventional concrete (CC) material with green concrete (GC) in the non-structural concrete works of a residential building in New Borg El-Arab City, Egypt. It attempts to establish what the effects are of using GC on cement, natural aggregates, and CO2 emissions in the design phase. By using a design-based solution (DBS), we began with redesign, reduce, reselect, reuse, and recycle strategies to find an optimal solution for applying recycle aggregate concrete (RAC) as a replacement material in selected building parts, such as the internal floor, external sidewalk, entrance steps, and wall boundary. AutoCAD software and 3Dmax were used to modify the original design and obtain two design references with four different scenarios. Comparative analyses were applied to investigate the effects of different concrete materials. The results show a reduction of about 19.4% in cement consumption in terms of the total concrete of the building and a 44.5% reduction in CO2 emissions due to the reduction of cement in specific building parts. In addition, this solution decreased natural coarse aggregate (NCA) consumption by 23.7% in the final concrete. This study recommends that GC materials close the loop of cementitious material consumption to reduce environmental impacts and achieve sustainability in the Egyptian building sector.

Cím:Crop Residues Stimulate Yield-Scaled Greenhouse Gas Emissions In Maize-Wheat Cropping Rotation In A Semi-Arid Climate / Morad Mirzaei, Manouchehr Gorji Anari, Maurício Roberto Cherubin, Nermina Saronjic, Seyed Mohammad Nasir Mousavi, Azin Rooien, Mohammad Zaman, Andrés Caballero-Calvo

Megjegyzések:Mitigating yield-scaled greenhouse gas emissions (YSE) is beneficial for enhancing crop yield, reducing greenhouse gas (GHG) emissions, and advancing climate-smart agronomic management practices. This study aims to evaluate the impact of different crop residue rates? 100% (R100), 50% (R50), and residue removal (R0) ? on the YSE indicator within a maize-wheat cropping rotation under both conventional tillage (CT) and no-tillage (NT) systems in a semi-arid region. In the NT system, crop residues had a notable effect on the YSE indicator for wheat. Specifically, R0 exhibited a 39% and 20% decrease in YSE for wheat compared to R100 and R50, respectively. Interestingly, crop residue did not significantly influence YSE for maize under the NT system. On the other hand, in the CT system, YSE for maize in R0 was 33% and 25% lower than that in R100 and R50, respectively. Additionally, compared to R0, there were observed increases of 28% and 20% in YSE for wheat in R100 and R50 under the CT system, respectively. Our findings show that crop residue removal decreases YSE under both CT and NT systems. However, given that this practice degrades soil quality and results in lower yields, it is not considered a sustainable management practice compared to residue retention options. This research highlights the importance of evaluating GHG mitigation strategies by concurrently considering both emissions and crop production. Nevertheless, it is essential to conduct off-site assessments of GHG emissions from crop residue application and also engage in long-term studies to comprehend the full potential of crop residue management on YSE.
