Methane (CH4) and nitrous oxide (N2O) are the two most important greenhouse gases (GHG) from flooded paddy fields in Indonesia. This review aims to characterise CH4 and N2O emissions from flooded paddy fields by published data analysis and to examine the potential of biochar from rice straw (RSB) and rice husk (RHB) to mitigate the emissions in Indonesia. A comparison of various box-plot datasets of CH4 emissions showed that the different types of flooded paddy field soil cause varying amounts of CH4 emissions from various regions in Indonesia. Sequentially, CH4 emissions of flooded paddy fields from highest to lowest are Alluvial of Kalimantan and Sulawesi, Andisols of Java, Ultisols of Sumatra, Alfisols of Java and Bali and Inceptisols of Java and Bali, with a mean of 1062, 505, 446, 135 and 64 kg ha-1 season-1, respectively. The organic amendments application combined with chemical fertilisers is the principal driver of anthropogenic CH4 emissions from paddy fields. However, N chemical fertiliser application contributes only about 0.37% of the N2O flux, 0.69 kg ha-1 season-1. The produced biochar number was insufficient effectively to reduce CH4 and N2O emissions, at least 20 tonnes ha-1 year-1, in addition to the pyrolysis process to produce biochar, releasing CH4 emissions. Yet, with its recalcitrant properties and continuous application, RSB and RHB potentially reduce CH4 and N2O emissions from paddy fields.

Connectedness to Nature and the ability to perceive the restorative value of places characterised by the presence of natural elements are personal characteristics that, when appropriately measured, make it possible to predict an individual’s attitude towards pro-environmental behaviour. While these characteristics have an innate basis, they are also shaped by personal experiences and various cognitive, affective and sociocultural factors. In this exploratory study in North-eastern Italy, we delve into an interdisciplinary field that explores the relationship between the environment of the residential area and its impact on children's attitudes toward Nature. To do so, we conducted a comprehensive questionnaire amongst 533 primary schoolchildren, aged 6-11 years, to gauge their connectedness to Nature, their perceptions of restorativeness in surrounding natural settings, and their schoolyard environment. Drawing from optical satellite imageries, we calculated a combined multispectral index to assess the naturalness degree of participants' residential areas, focusing on their 68 residential areas, located in three administrative Italian Regions (Trentino Alto Adige, Friuli Venezia Giulia and Veneto), which were classified into four different classes with respect to their level of presence of natural areas ("coastal," "low," "average," "high"). By performing non-parametric tests for multiple comparisons amongst groups, we detected a significantly higher level of connectedness to Nature amongst children living in areas with high naturalness, compared to those living in areas with average or low naturalness. Perceived restorativeness scores exhibit a similar trend to that of connectedness to Nature, reinforcing the importance of natural spaces in fostering positive attitudes towards the environment. This result confirms that accessibility and the viewability of natural spaces, even semi-natural ones, seemed to play a crucial role in children's preference for these environments. However, schoolyards were consistently perceived as less regenerative than natural places, regardless of the naturalness of the neighbourhood. These findings raise intriguing questions about the potential consequences of inadequate exposure to Nature on children's affiliation to the natural world and possible subsequent effects on pro-environmental behaviour in adulthood. By shedding light on the complex interplay between personal characteristics, environment and attitudes towards Nature, our study underscores the significance of fostering a deeper connection with natural spaces to nurture a sustainable and environmentally conscious society.

Reconstructing the history (spatio-temporal patterns) of biological invasions at a small spatial scale is challenging, notably because the required data are often not available in sufficient quantity and quality. In this study, we present a mixed approach using six different data sources to explore the spreading history of four non-native invasive tree species, Ailanthus altissima , Celtis occidentalis , Prunus serotina and Acer negundo in a high conservation value foreststeppe habitat with an area of 1000 ha (Peszér Forest, Central Hungary). We carried out a literature search, compiled all the archived and currently valid data of the National Forestry Database (NFD) in a GIS database, conducted a full-coverage field survey, mapped all the large/old tree specimens and carried out annual ring counts, performed a hotspot analysis on the abundance data provided by the field survey and gathered local knowledge. Each of these approaches proved indispensable and their complementary use made it possible to reconstruct the invasion history of all four tree species. According to the available source literature, P. serotina was first planted in the area in 1937 and the first known occurrence of A. altissima could also be traced back to the 1930s. The examination of large specimens of C. occidentalis and querying the NFD for data related to A. negundo provided evidence that these species have been present in the area since at least the 1940s. However, based on the NFD and local knowledge, it is certain that the rapid expansion of the four tree species occurred simultaneously and only around the turn of the millennium, with a lag of at least 60-70 years. The exploration of local knowledge revealed three possible explanations, which interestingly also coincided in time. With the change in the political regime, the intensity of forest use started to decrease in the 1990s, the population of game was drastically reduced at the end of the decade and droughts became more frequent from 2000 onwards. The field survey clearly showed that these tree species were 2-3 times more prevalent and abundant than the relevant NFD data indicated. Finally, the primary hotspots of A. altissima and A. negundo overlapped with the locations of their first known occurrences, while in the case of C. occidentalis and P. serotina , they did not. However, local knowledge revealed that the former two had been ignored since at least the 1950s, while the latter two were occasionally planted until the 1990s. It is likely that the primary hotspots of C. occidentalis and P. serotina indicate the locations of these undocumented plantations.

Semi-natural linear landscape elements, such as hedgerows, are vital structures within agricultural landscapes that have an impact on ecosystem processes and support biodiversity. However, they are typically omitted from green infrastructure planning, which could lead to significant undervaluing of landscapes and their multifunctionality in terms of ecosystem service supply. Using the InVEST (Integrated Valuation of Ecosystem Services and Tradeoffs) model suite, we tested the effects of additionally including semi-natural linear landscape elements on the model outcomes for crop pollination, nutrient regulation, erosion regulation and water flow regulation ecosystem services supply. The results showed that linear semi-natural landscape elements contribute positively to the landscape’s multifunctionality. Small changes have been identified for water flow regulation, whereas, considering both spatial extent and magnitude of the changes, the greatest changes have been found with respect to the supply of pollination and nutrient regulation. Direct proximity of the linear elements had the greatest effect on ecosystem service supply, in particular with regard to pollination. Based on our results, a more pronounced consideration of semi-natural linear landscape elements as an important element of green infrastructure is advisable.
半自然的线性景观元素，如树篱，是农业景观中的重要结构，对生态系统过程产生影响并支持生物多样性。然而，它们通常在绿色基础设施规划中被忽略，这可能导致严重低估景观及其在生态系统服务供应方面的多功能性。利用InVEST (Integrated Valuation of Ecosystem Services and Tradeoffs)模型套件，我们测试了额外加入半自然线性景观元素对作物授粉、养分调节、侵蚀调节和水流调节生态系统服务供应模型结果的影响。结果表明，线性半自然景观元素对景观的多功能性有积极的促进作用。水流调节的变化较小，而从空间范围和变化幅度来看，最大的变化是传粉供应和养分调节。直接接近线性要素对生态系统服务供应的影响最大，特别是在授粉方面。基于我们的研究结果，将半自然的线性景观元素作为绿色基础设施的重要元素是可取的。

The cultural ecosystem service (CES) has been rarely expressed in the area of urban landscape and design. This study tries to find a framework to apply the CES usage in the literature of landscape design. The results show that most indicators have expanded in the areas of “landscape elements” followed by the “ecological infrastructures.” In addition, the aesthetic indicators in the biological aspect have been mainly focused on plants; moreover, birds have been more considered than the other species. Other findings indicate that, in addition to the existing proceedings, the link with the sustainable development objectives, the effects of the drivers for change and the ecosystem’s improper services' indicators are factors that should be considered in the area of landscape design in a framework of ecosystem cultural services.

Urban rivers play a crucial role in providing ecosystem services (ES) that contribute to the social well-being and quality of life of urban inhabitants. However, rapid urbanisation has led to the progressive degradation of these rivers, affecting their capacity to deliver ES and resulting in significant socio-ecological impacts. This study performs a participatory mapping of the non-monetary social values (positives and negatives), in the urban Zamora and Malacatos Rivers and their ESs, in Loja, Ecuador, to understand community perceptions and preferences in a context of degraded landscapes as a complementary category of analysis to traditional approaches. Methodologically, the collection, analysis and mapping were carried out using public participation GIS (PPGIS) based on surveys. This method facilitated the integration of social data with biophysical variables. The most relevant of the ten social values studied were positives: Learning, Aesthetic, Therapeutic and negatives: Displeasure, Deficient and Inaccessible Infrastructure and Threat of Flooding. We revealed different spatial patterns for each ES social value, where positive value locations exhibited a dispersed pattern, with clusters in peripheral areas, while negative value locations exhibited a clustered pattern in the city centre. The environmental variable with the most significant contribution was the Horizontal Distance to Green Areas. These findings enhance our understanding of the social values and preferences associated with ES in urban river contexts. Furthermore, they provide valuable insights for identifying areas of opportunity and conflict, informing community planning and effective management of the urban landscape.

Mangroves play an important role in coastal estuarine areas with different ecological functions, such as reducing the impact of waves and currents, accumulating biomass and sequestering carbon. However, estimation of terrestrial biomass in mangrove areas, especially in Vietnam, has not been fully studied. The application of unmanned aerial vehicles (UAV), mounted with multispectral cameras combined with field verification is an effective method for estimating terrestrial biomass for mangroves, as it reduces field survey time and allows for greater spatial range research. In this study, ground biomass was estimated for the mangrove area in the Dong Rui commune, based on multispectral image data obtained from UAV and survey results in 16 standard cells measuring actual biomass according to four regression models: Log-Log, Log-Lin, Lin-Log and Lin-Lin. The results of comparing the data from these four models show that the log-log model has the highest accuracy with a high correlation coefficient (R2 = 0.831). Based on the results of the analysis and selection of ground-based biomass estimation models, a biomass map was established for the UAV flying area in the Dong Rui mangrove forest with biomass values ranging from 20 Mg/ha to 150 Mg/ha. In summary, we present a biomass estimation method through four basic linear regression models for mangrove areas, based on multispectral image data obtained from ultrahigh-resolution UAV. The resulting research results can serve as a basis for managers to calculate and synchronise the payment of carbon services, thus contributing to effectively promoting the livelihoods of local people.

Ecosystem Accounting provides a framework to measure and value relationships amongst ecosystems, society and the economy. The accounts measure ecosystem extent, condition and services, providing the means to identify and internalise ecological degradation, as well as understanding the risks and dependencies of economic activities on the environment and tracking progress towards sustainable development. The OSPAR Convention, which concerns the protection of the Marine Environment for the North-East Atlantic, has committed to accounting for natural capital and ecosystem services, where the UN System of Environmental Economic Accounting – Ecosystem Accounting (SEEA EA) provides an international accounting standard for guidance in compiling accounts. Here, we describe the first attempt in compiling accounts aligned with SEEA EA at a Regional Sea scale. We: (i) identified existing open access data, (ii) produced accounts for selected ecosystems and valued their services and asset value and (iii) identified challenges and lessons learned. For ecosystem services, we measured fish provisioning, carbon sequestration and outdoor recreation from coastal and marine environments across OSPAR contracting parties. The exercise identified lack of fitting data at regional level, spatially-explicit linkages and harmonisation need to be overcome to further expand accounts. This work represents an initial step to progress on ecosystem accounting and demonstrates that even with limited data and incomplete time-series, accounts can start being compiled to identify data gaps and prioritising next steps.

This work represents an initial step to progress on ecosystem accounting and demonstrates that even with limited data and incomplete time-series, accounts can start being compiled to identify data gaps and prioritising next steps.","PeriodicalId":36908,"journal":{"name":"One Ecosystem","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42204134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Harnessing reliable and relevant information on ecosystems requires focusing and prioritising information acquisition on dimensions of interest. As a boundary object between ecosystem monitoring, research and public decision-making, ecosystem accounting can serve this purpose. We develop an argument in favour of a set of accounts, consistent with the statistical standard part of the System of Environmental-Economic Accounting (SEEA-EA), that explicitly links monetary accounts to ecosystem extent and condition accounts. The ecosystem condition account is structured in three categories reflecting the main values motivating integrated ecosystem management targets and notions of «good ecological status». These categories are: (i) the maintenance of their heritage dimensions, (ii) their capacity to sustainably provide ecosystem services and (iii) the maintenance of their overall functionality. We discuss how such ecosystem accounts and associated monitoring can form the basis both for assessing an ecological debt by using a cost-based approach and for designing an action-orientated information system suitable to support the transition towards sustainable societies.

The Cienaga Grande de Santa Marta Ramsar Site (CGSM) is the most important Caribbean estuarine wetland in Colombia. The site represents a strategically important ecosystem supporting the national and local economy. However, their ability to provide ecosystem services has been seriously affected mainly due to changes in land use, disturbances of water flows, man-made climate change and interannual climatic variability. These circumstances led to its inclusion in the Montreux Record, a register of wetland sites on the ‘List of Wetlands of International Importance’ where variations in ecological character have happened, are happening or are likely to happen as an outcome of technological developments, pollution or other human interference. This paper presents the first account of marine and coastal ecosystems developed in Colombia at the Cienaga Grande de Santa Marta. Following the principles for ecosystem accounting of the System of Environmental-Economic Accounting—Ecosystem Accounting (SEEA EA), we developed accounting tables of extent and condition of ecosystems, biophysical and monetary flows of climate regulation and fishing supply and the monetary account of ecosystem assets. Results of the ecosystem account allow visualising the importance of ecosystem services of the wetland, its capacity to provide economic benefits, social welfare and livelihoods at local and national level. Finally, we identify main gaps of information, highlight the applicability of ecosystem accounting to policy- and decision-making on economic and environmental issues and evaluate the challenges to implement it.
Cienaga Grande de Santa Marta Ramsar湿地（CGSM）是哥伦比亚最重要的加勒比海河口湿地。该网站代表了一个具有重要战略意义的生态系统，支持国家和地方经济。然而，它们提供生态系统服务的能力受到了严重影响，主要是由于土地利用的变化、水流的干扰、人为气候变化和年际气候变化。这些情况导致它被列入蒙特勒记录，这是一个“国际重要湿地名录”上的湿地遗址登记册，由于技术发展、污染或其他人类干扰，这些湿地的生态特征已经发生、正在发生或可能发生变化。本文首次介绍了哥伦比亚在圣玛尔塔大运河开发的海洋和沿海生态系统。根据环境经济核算体系的生态系统会计原则——生态系统会计（SEEA EA），我们制定了生态系统范围和状况、气候调节和渔业供应的生物物理和货币流量以及生态系统资产的货币账户的会计表。生态系统账户的结果可以直观地显示湿地生态系统服务的重要性，湿地在地方和国家层面提供经济效益、社会福利和生计的能力。最后，我们确定了信息的主要差距，强调了生态系统会计在经济和环境问题的政策和决策中的适用性，并评估了实施该会计的挑战。
