This study provides a comprehensive bibliometric analysis of skyscraper greenery research from 2003 to 2023, employing advanced tools such as CiteSpace and Bibliometrix to assess publication trends, elucidate key research themes, and identify prevailing knowledge gaps. The findings underscore the environmental benefits of skyscraper greenery, including its role in alleviating the urban heat island effect, improving air quality, and enhancing urban biodiversity. Additionally, economic advantages, such as reductions in energy consumption and operational costs, further highlight its multifaceted utility. Carbon sequestration within skyscraper greenery primarily occurs through vegetation’s photosynthetic processes, which are influenced by plant species, substrate composition, and system design.

This chapter aims to explore the critical role of forests in mitigating global climate change by enhancing carbon sequestration. The authors synthesized the research of global forests carbon sink, showcasing their significant carbon sink potential. Drawing on previous studies, they introduced the contributions of various forest types and management practices to bolster forest carbon sequestration. Case studies of successful nature-based solutions (NbS) projects are highlighted to illustrate effective strategies for increasing forests carbon sinks. Additionally, the authors outlined methodologies for quantifying forest carbon sequestration, encompassing field-based approaches, remote sensing technologies, and advanced modeling techniques.

Macroalgae farming not only holds significant economic value but also contributes substantially to carbon sequestration, and therefore has gained intensified attention globally under climate change scenarios. However, its sustainability is increasingly threatened by anthropogenic and environmental changes. The health and resilience of macroalgae are intrinsically linked to their associated microbiomes, offering an untapped opportunity to enhance macroalgal farming through microbiome manipulation. In this review, the authors have summarized the current understanding of macroalgal microbiomes, highlighting critically underexplored microbial components, such as overlooked taxa, host specificity, and the environmental factors influencing microbiome composition, which hinder the development of effective microbiome engineering strategies.

Salt marshes are known as key ecosystems for nature-based climate mitigation through organic carbon sequestration into their sediment beds, but at the same time they are affected by accelerating sea level rise induced by climate warming. Consequently, an important question is how organic carbon accumulation rates (OCAR) of salt marshes will respond to future accelerating rates of relative sea level rise (RSLR). This study studies the OCAR over four decades at two nearby salt marsh sites in the Netherlands, with similar environmental conditions, but with different RSLR rates.

This review discusses the sequestration capacity, technical classification, mechanisms, and factors influencing carbon sequestration by microalgae (MCS) in livestock wastewater. First, the carbon emission characteristics of livestock farm are discussed, concluding that, compared with those from enteric fermentation, emissions from waste management are characterized by dispersed emission points, lack of obvious emission patterns, and difficulties in gas collection. Secondly, the use and potential of MCS in livestock wastewater are summarized, with emphasis on the mechanisms involved (both heterotrophic and autotrophic MCS).

Consistent and accurate monitoring of changes in soil organic carbon stocks and net greenhouse gas emissions, reporting, and their verification is key to facilitate investment in sustainable land use practices that maintain or increase soil organic carbon stocks, as well as to incorporate soil organic carbon sequestration in national greenhouse gas emission reduction targets. Building up on an initial review of monitoring, reporting and verification (MRV) schemes with a focus on croplands, grasslands, and forestlands the authors develop a framework for a modular, scalable MRV system. They then provide an inventory and classification of selected MRV methodologies and subsequently “score” them against a list of key characteristics.

This review assesses the feasibility of reusing treated wastewater for irrigation in agricultural soils as a strategy for nutrients recycling and mitigation of CO2 emissions. Through a literature review, it was examined wastewater sources enriched with carbon and nutrients, including municipal wastewater and associated sludge, vinasse, swine wastewater, as well as wastewater from the food industry and paper and pulp production. The review also explores the dynamics of organic matter within the soil, discussing the aspects related to its potential conversion to CO2 or long-term storage.

Soil organic carbon (SOC) accrual, and particularly the formation of fine fraction carbon (OCfine), has a large potential to act as sink for atmospheric CO2. For reliable estimates of this potential and efficient policy advice, the major limiting factors for OCfine accrual need to be understood. The upper boundary of the correlation between fine mineral particles (silt + clay) and OCfine is widely used to estimate the maximum mineralogical capacity of soils to store OCfine, suggesting that mineral surfaces get C saturated. Using a dataset covering the temperate zone and partly other climates on OCfine contents and a SOC turnover model, the authors provide two independent lines of evidence, that this empirical upper boundary does not indicate C saturation.

The authors have integrated several ecological models (dynamic stand model FORRUS-S, soil organic matter model Romul_Hum, statistical climate generator SCLISS and process-based forest ecosystem model EFIMOD3) to simulate the ecosystem dynamics at the regional level in several study areas within the forest zone of the European part of Russia. The simulation results reflected both the direct effects of climate change and forest management actions on ecosystem carbon pools, and the indirect effects through changes in species composition. The simulation experiments were spatially detailed at the level of individual forest management units, thereby revealing the influence of habitat conditions on the rate of carbon sequestration under the influence of environmental factors.
