Forest shelterbelts and windbreaks play a vital role in protecting ecosystems, mitigating climate change effects, and enhancing agricultural productivity. These vegetative barriers serve as effective tools for soil conservation, reducing wind and water erosion while improving soil fertility. Additionally, they contribute to biodiversity preservation by providing habitat corridors for various plant and animal species. Their role in microclimate regulation, such as temperature moderation and increased humidity retention, further enhances agricultural yields and ecosystem stability. This study examines the historical evolution, design principles, and contemporary applications of forest shelterbelts and windbreaks, drawing insights from scientific research and case studies worldwide. It highlights the economic and environmental benefits, including improved air quality, carbon sequestration, and water management, making them crucial components of sustainable land use strategies. However, challenges such as land use competition, maintenance costs, and policy constraints are also analyzed, underscoring the need for integrated approaches to their management. Through a comprehensive bibliometric analysis of the existing literature and field studies, this paper emphasizes the necessity of strategic planning, community involvement, and adaptive policies to ensure the long-term sustainability of forest shelterbelts and windbreaks. The findings contribute to a broader understanding of their role in combating environmental degradation and promoting ecological resilience in the face of ongoing climate challenges.

Land degradation is a critical global issue threatening environmental health, food security, and sustainable development. Afforestation has emerged as a vital nature-based solution to combat land degradation by restoring soil structure, enhancing water regulation, sequestering carbon, and supporting biodiversity. Despite extensive research on degraded lands and forestry, there remains a notable gap specifically addressing afforestation of degraded lands, which this study aims to fill through a comprehensive bibliometric and qualitative review of global trends, species use, ecological impacts, and restoration techniques. This study was conducted in two main phases: a bibliometric analysis followed by a traditional literature review. A total of 631 publications published between 1993 and 2024 on the afforestation of degraded lands were analyzed, with the majority consisting of research articles (87%), followed by review papers (5%), book chapters (4%), and conference proceedings (4%). In conclusion, afforestation of degraded lands is a well-established and actively studied field, supported by a substantial body of empirical research and expanding interdisciplinary engagement. The literature encompasses a wide variety of publication types, enabling both the production and dissemination of knowledge across ecological, technical, and socio-economic areas.

Poplars (Populus L.) are fast-growing, widely distributed trees with high ecological, economic, and climate-mitigation value, making them central to diverse agroforestry systems worldwide. This study presents a comprehensive bibliometric and content-based review of global poplar-based agroforestry research, using Scopus and Web of Science databases and a PRISMA-guided screening process to identify 496 peer-reviewed publications, covering publications from 1987 to 2024. Results show a steady rise in scientific output, with a notable acceleration after 2013, dominated by agriculture, forestry, and environmental sciences, with strong international contributions and research themes focused on productivity, carbon sequestration, biodiversity, and economic viability. A wide range of Populus species and hybrids is employed globally, supporting functions from crop production and soil enhancement to climate mitigation and ecological restoration. Poplar-based systems offer substantial benefits for soil health, biodiversity, and carbon storage, but also involve trade-offs related to tree–crop interactions, such as competition for light reducing understory crop yields in high-density arrangements, management intensity, and regional conditions. Poplars provide a wide array of provisioning, regulating, and supporting ecosystem services, from supplying food, fodder, timber, and biomass to moderating microclimates, protecting soil and water resources, and restoring habitats, while supporting a broad diversity of agricultural and horticultural crops. However, several critical gaps—including a geographic research imbalance, socio-economic and adoption barriers, limited understanding of tree–crop interactions, and insufficient long-term monitoring—continue to constrain widespread adoption and limit the full realization of the potential of poplar-based agroforestry systems.

Oak species (Quercus spp.) represent one of the most widespread and ecologically important groups of woody plants in the Northern Hemisphere, forming dominant forest ecosystems across temperate, Mediterranean, subtropical, and montane regions. Due to their longevity, high wood density, extensive root systems, and large biomass, oaks play a significant role in terrestrial carbon cycling and long-term carbon storage. However, a comprehensive synthesis of the contribution of oak forests to carbon sequestration remains limited. This review integrates a systematic bibliometric assessment with a qualitative synthesis of the peer-reviewed literature to evaluate the role of oak species and oak-dominated forests in carbon sequestration and climate change mitigation. A total of 656 publications indexed in Scopus and Web of Science were analyzed, revealing increasing research activity after 2008 and a broad geographic distribution of studies, with the highest contributions from the United States, Spain, China, and Germany. The reviewed studies demonstrate that oak ecosystems function as substantial and durable carbon sinks, storing carbon in aboveground biomass, belowground biomass, deadwood, litter, and soil organic carbon pools. Carbon sequestration is influenced by stand age, site conditions, species composition, and management practices. This review highlights oak forests as resilient, multifunctional ecosystems, with a critical role in nature-based climate solutions and sustainable forest management.

Agronomic practices can have a negative impact on soil health and quality and ecosystem resilience. The objectives of the study were (1) to evaluate the soil chemical properties and microbial abundance under short-term application of organic and mineral fertilizers and different cultivated crops and (2) to observe the antifungal efficacy of microorganisms isolated from the studied soil. A field trial was conducted in the 2021–2022 period on a preluvosoil-type soil in four randomized blocks with eight fertilizer treatments based on manure compost (MC) and MC + mineral fertilizer (V1—control-soil; V2—NPK only; V3—15 t/ha MC; V4—15 t/ha MC + NPK; V5—30 t/ha MC; V6—30 t/ha MC + NPK; V7—60 t/ha MC; and V8—60 t/ha MC +NPK) and four crops (winter wheat—Triticum aestivum L., maize—Zea mays L., soybean—Glycine max L., and a mixture of perennial grasses and legumes). In almost all treatments, the soil pH decreased during the summer–autumn period. The organic carbon (C_org) and humus contents increased compared to the initial state of the soil after the application of different doses of MC and MC + NPK fertilization in almost all treatments. The microbial load of the soil was influenced by the fertilization regime and crop species, but there were no significant differences between the variants. The highest bacterial load was recorded in soil cultivated with a mixture of perennial grasses and grain legumes, i.e., in the variant with 15 t/ha MC, followed by soil cultivated with maize and fertilized with 30 t/ha and 60 t/ha MC. A higher number of fungi was observed in the mixture of perennial grasses and legumes, and Rhizobium population was higher, especially in the winter wheat plots, despite the fertilization regime. The antifungal efficacy of the microorganisms isolated from the samples was medium to low, except in the winter wheat experiment, where the efficacy against Fusarium culmorum was medium to high and against other pathogens was medium. In the other crops within the experiment, the antagonistic activity of the soil microorganisms was medium to low.

The paper aims to present the evolution of soils located on slope over 24 years by comparing data obtained through successive mapping in 2000 and 2024.The research aimed to characterize the soils in the upper third of the Valea cu Drum hydrographic basin, located on the right slope of the Slănic stream in Buzău county. Two successive pedological mappings were carried out in this area in 2000 and 2024. The soils in the studied area fall into two classes according to the Romanian Soil Taxonomy System: Chernozems ( luvic Chernozems and haplic Phaeozems) and Anthrosols (calcareous Anthrosols). These three soil types have the highest share in the hilly area of Buzău County. In the upper third of the left slope of the studied watershed, wide terraces were built between 1993 and 1996, with the following dimensions: platform height of 12 m, height of embankment and cut-off of 2.3 m, platform slope ip=10%, excavation volume (Vfill) was equal to that of filling (Vfill) of 10 m3/ ml with the aim of reducing soil losses through erosion. Through the pedological mapping carried out in 2024, the three main profiles were opened, in which the pedogenetic horizons were delimited through morphological analysis carried out in the field and soil samples were collected from each pedogenetic horizon for laboratory analysis: granulometric analysis, reaction, carbonate and humus content.The June-September 2024 interval is characterized by higher temperatures and lower precipitation, which characterizes a dry year from a climatic point of view. The air temperature values during the vegetation period recorded in 2024 are higher by 1oC in June, by 2.4oC in July, by 3oC in August and by 5.4oC in September compared to those recorded in 2000. Lower air temperature values in 2024 compared to those in 2000 were recorded in April by 1.4oC and in May by 3.6oC. The total amount of precipitation that fell during the vegetation period in 2000 is 321.6 mm compared to 247.3 mm in 2004, a difference of 74.3 mm showing a deficit of precipitation in 2024.The calcareous Anthrosols profile was located in the upper third of the terraced left slope, on the platform of the T2 terrace in the clearing, and has the profile: Aho-Ck. The haplic Phaeozems profile was located on the right slope of the watershed with hay use, having the profile: Amtk-ACk-Ck1-Ck2. The soil is slightly eroded. The luvic Chernozems profile was located on the left slope of the watershed and has the profile: Aom-AB-Bt1-Bt2-C, the soil is moderately eroded.
