A STUDY OF STAKEHOLDERS' PERSPECTIVES ON MULTI-FUNCTIONAL FORESTS IN EUROPE

<p>For centuries, mountain forests in the Alps have provided essential ecosystem services such as wood production and protection from natural hazards (e.g. avalanches and landslides), which enable mountain societies to thrive in these marginal environments. These ecosystem services are affected by climate and land use change, as well as changes in societal demand and management regimes. In recent years, the management of mountain forests has been increasingly driven by forest disturbances, such as windthrow, bark beetle outbreaks, and forest fires. The increasing rate of disturbances has the potential to convert forests from carbon sinks to carbon sources, and may also affect the provision of other ecosystem services, such as avalanche protection. The capacity of forests to provide services, their vulnerability to disturbance, and their resilience depend on their structure, composition and management regime. Forests with a heterogeneous structure and species composition are expected to better maintain their protection function after disturbances.</p><p>Information on forest structure and its link to functions and services is available from a variety of sources, from Earth Observation and in-situ data, existing process-based models, to local expert knowledge. We use Bayesian Networks to integrate these different types of information and model ecosystem services (carbon sequestration, wood production, and avalanche protection) in the Swiss Alps. This probabilistic modelling approach allows us to identify knowledge gaps and explore uncertainties in the future provision of ecosystem services. Since disturbances are a major source of uncertainty, we combine remote sensing and forest management data to investigate how disturbance severity and post-disturbance recovery are influenced by stand characteristics, such as structural heterogeneity. Based on this analysis, we discuss how forest management can help ensure the provision of mountain forest ecosystem services under changing disturbance regimes. </p>

Provisioning ecosystem services supply and demand: The role of landscape management to reinforce supply and promote synergies with other ecosystem services

Among the soil-based ecosystem services (ES), nutrient cycling and carbon sequestration have direct influence on the biogeochemical cycles and greenhouse gas emissions affecting provision of other ES that support human existence. We reviewed methods to assess the two key ES by identifying their strengths and weaknesses and have made suggestions for using appropriate methods for better understanding of the ecosystem functions for the provision of ES. Relevant papers for the review were chosen on the basis of (i) diversity of studies on the two key ES in different ecosystems, (ii) methodologies applied and (iii) detailed descriptions of the trial locations in terms of vegetation, soil type, location and climatic information. We concluded that (i) elemental stoichiometrical ratios could be a potential approach to assess the health of ecosystems in terms of provision of the two ES discussed, (ii) stoichiometric imbalances need to be avoided between the supply and the demand of the nutrients to maintain the ES provision in terrestrial ecosystems and (iii) stoichiometric ratios can act as a management tool at a field, farm and at landscape level, to complement other compositional biodiversity and functional diversity approaches to ensure sustainable provision of ES.

Over the past few decades, both scientific community and policy makers focused on ecosystem services provided by forests due to their positive impact on human well-being and quality of life. In literature, there is a broad consensus that assessing and mapping ecosystem services is one of the most demanding challenges to address, but at the same time a key tool for effective forest management. This study aims to develop a method suitable to assess and map ecosystem services provided by deadwood islands located in managed forests. To this end, a geospatial analysis was developed in a case study in Italy to conduct an integrated investigation of ecosystem services provided inside and outside the deadwood islands (timber production, stand stability, outdoor recreation, biodiversity conservation). The innovative nature of this study is that it assessed ecosystem services provided by the deadwood islands within managed forests, an aspect that has not yet been investigated in the international literature. The results showed a positive correlation between the four ecosystem services provided by forests and in particular between: timber production and biodiversity conservation; outdoor recreation and stand stability; biodiversity conservation and stand stability. In addition, the results highlighted that the interventions implemented in the deadwood islands have a positive effect on the biodiversity conservation without compromising the provision of other ecosystem services. From a practical standpoint, the results of this study provide forest managers with insights into the impacts of deadwood islands on a wide range of ecosystem services, not just biodiversity. By doing so, managers can better understand the real impacts of this management system on forests.

Ecosystem services (ES) are growing fields of research. It helps to provide an inherent way to understand the synergy and trade-offs between human beings and their natural environment. Regulatory ecosystem services (RES) are significantly important to maintaining the world in which people can live, and control the negative effects of flood, disasters, and diseases. It can also provide regulatory services like ecosystem protection, human safety, and the provision of other ES. However, emerging ES decision-making agendas focus on ES that is tangible and has a direct link with human well-being. Thus, the attention given to RES is low due to its less tangible benefits and complexity to measure the benefits. Disregarding and lack of attention from policymakers and scientific community may lead to unintended risks to human well-being and significant influences on the provision of other ES. This study describes the research trends on RES, knowledge generated, and the major limitation. We concluded that though there is an exponential growth of scientific publications on ES, no adequate studies were found on RES. Also, the existed studies varied in their size and types of RES indicators covered, habitats/ecosystems, and geographic extent addressed. There was also a lack of connecting knowledge generated on the benefits of RES with the national policy of natural resource management, inconsistency of ES classification, and methodological diversity. Therefore, scientific communities are promoted to link RES studies with human health. Besides, the researcher should give priority for the least studied ecosystems and its services, developing robust methodology, and proposing management options to enhance the regulatory services of ecosystems.

The Democratic Republic of Congo (DRC) is involved in the implementation of an international Payment for Ecosystem Services (PES) (UNEP: Developing international payments for environmental services: a technical discussion (Background Paper), 2006) mechanism, namely “Reduced Emissions from Deforestation and forest Degradation in the developing countries and the conservation, sustainable forest management and the enhancement of forest carbon stocks in the developing countries” (REDD+). However, the laws of the DRC are insufficient to achieve a sustainable PES and REDD+ implementation. Based on indicators on land tenure security, classical conditions of contracts, 3E+ REDD+ criteria and measures on conservation and restoration, this chapter analyses the laws related to PES in force in the DRC in order to obtain a more sustainable preservation of ecosystem services. The chapter focuses on four ecosystem services: carbon sequestration and storage, biodiversity protection, watershed protection and landscape beauty. Several criteria have been applied to assess the potential of the DRC PES laws to promote a sustainable preservation of ecosystems and ecosystem services. A first set of well-known criteria are the 3 E+ REDD+ criteria, which entails that to achieve a successful REDD+ implementation, the REDD+ project should be effective, costly efficient, equitable and bring co-benefits. Effectiveness refers to the achievement of environmental goals. Cost efficiency means that the project should attempt to reach the environmental goals through reasonable financial means. Equity fits with the inclusive capacity of the project. Four co-benefits are distinguished, namely biodiversity conservation, governance, adaptation of climate change and improvement of social conditions. Secondly, this chapter refers to classical contract conditions from French and Belgian Civil Law inherited by Congolese Civil Law. These conditions are the consent of the parties, the capacity of parties, the existence of an object and the legal purpose. Thirdly, the chapter refers to the indicators on conservation and restoration measures and on land tenure security (property right titles and clear borders). The chapter demonstrates that there is a need to update or enforce the existing laws related to PES applied in the DRC in order to increase the preservation of ecosystem services. The chapter argues that the transformation of the existing laws would positively influence the implementation of SDG 13 and 15.

Ant biodiversity and ecosystem services in bioenergy landscapes

Rangelands offer various goods and ecosystem services (ES) besides providing forage for commercial livestock production. An analysis of research published in the journals of the Grassland Society of Southern Africa from 1966 to 2023 revealed a widening focus on different consumptive and non-consumptive ES. While livestock remains the primary focus, there is a growing interest in other provisional, regulatory, supporting, and cultural ES and uses of rangeland. The term ‘ecosystem services’ started to appear in articles from the early 2000s, marking a shift towards a richer discourse on the multifarious resources and services rangelands can provide to diverse users. A transition from ‘veld’ to ‘rangeland’ terminology occurred at the onset of the 21st century, though ‘veld’ remains mentioned. Recognition of communal and pastoral users of rangelands has expanded since the mid-1980s, alongside more frequent studies on conservation of biodiversity and commercial game production. Research has increasingly focused on understanding ecological processes supporting rangeland productivity and the provision of other ES, including carbon sequestration for climate regulation. Cultural and recreational values of rangelands have received little research attention. Overall, the journals’ corpus is evolving to reflect a broader perspective on valuing and managing multi-functional rangelands, which is in alignment with global research trends.

Trade-offs between fire prevention and provision of ecosystem services in Slovenia

Soil health is a term used to describe the general state or quality of soil, and in an agroecosystem, soil health can be defined as the ability of the soil to respond to agricultural practices in a way that sustainably supports both agricultural production and the provision of other ecosystem services. Conventional agricultural practices cause deterioration in soil quality, increasing its compaction, water erosion, and salinization and decreasing soil organic matter, nutrient content, and soil biodiversity, which negatively influences the productivity and long-term sustainability of the soil. Currently, there are many evidences throughout the world that demonstrate the capability of conservation agriculture (CA) as a sustainable system to overcome these adverse effects on soil health, to avoid soil degradation and to ensure food security. CA has multiple beneficial effects on the physical, chemical, and biological properties of soil. In addition, CA can reduce the negative impacts of conventional agricultural practices on soil health while conserving the production and provision of soil ecosystem services. Today, agricultural development is facing unprecedented challenges, and CA plays a significant role in the sustainability of intensive agriculture. This review will discuss the impact of conservation agricultural practices on soil health and their role in agricultural sustainability.

Abstract. Terrestrial carbon resources are major drivers of development in West Africa. The distribution of these resources co-varies with ecosystem type and rainfall along a strong Northeast-Southwest climatic gradient. Soil organic carbon, a strong indicator of soil quality, has been severely depleted in some areas by human activities, which leads to issues of soil erosion and desertification, but this trend can be altered with appropriate management. There is significant potential to enhance existing soil carbon stores in West Africa, with benefits at the global and local scale, for atmospheric CO2 mitigation as well as supporting and provisioning ecosystem services. Three key factors impacting carbon stocks are addressed in this review: climate, biotic factors, and human activities. Climate risks must be considered in a framework of global change, especially in West Africa, where landscape managers have few resources available to adapt to climatic perturbations. Among biotic factors, biodiversity conservation paired with carbon conservation may provide a pathway to sustainable development, and biodiversity conservation is also a global priority with local benefits for ecosystem resilience, biomass productivity, and provisioning services such as foodstuffs. Finally, human management has largely been responsible for reduced carbon stocks, but this trend can be reversed through the implementation of appropriate carbon conservation strategies in the agricultural sector, as shown by multiple studies. Owing to the strong regional climatic gradient, country-level initiatives will need to consider carbon sequestration approaches for multiple ecosystem types. Given the diversity of environments, global policies must be adapted and strategies developed at the national or sub-national levels to improve carbon storage above and belowground. Initiatives of this sort must act locally at farmer scale, and focus on ecosystem services rather than on carbon sequestration solely.

Climate change is increasing the severity and frequency of droughts around the globe, leading to tree mortality that reduces production and provision of other ecosystem services. Recent studies show that growth of mixed stands may be more resilient to drought than pure stands. The two most economically important and widely distributed tree species in Europe are Norway spruce (Picea abies (L.) Karst) and Scots pine (Pinus sylvestris L.), but little is known about their susceptibility to drought when coexist. This paper analyses the resilience (resistance, recovery rate and recovery time) at individual‐tree level using a network of tree‐ring collections from 22 sites along a climatic gradient from central Europe to Scandinavia. We aimed to identify differences in growth following drought between the two species and between mixed and pure stands, and how environmental variables (climate, topography and site location) and tree characteristics influence them. We found that both the timing and duration of drought drive the different responses between species and compositions. Norway spruce showed higher vulnerability to summer drought, with both lower resistance and a longer recovery time than Scots pine. Mixtures provided higher drought resistance for both species compared to pure stands, but the benefit decreases with the duration of the drought. Especially climate sensitive and old trees in climatically marginal sites were more affected by drought stress. Synthesis. Promoting Scots pine and mixed forests is a promising strategy for adapting European forests to climate change. However, if future droughts become longer, the advantage of mixed stands could disappear which would be especially negative for Norway spruce.

Ecosystem services across contrasting forested landscapes in Queensland's Wet Tropics Bioregion: contemporary patterns, processes and likely future trends under a changing climate

A number of critical issues have emerged in the Hindu Kush Himalayan (HKH) region as reflected in the downward spiral of resource degradation, increasing rural poverty, and food and livelihood insecurity in mountainous regions. New and comprehensive approaches to mountain development are needed to identify sustainable resource development practices such as Sustainable Land Management (SLM), to strengthen local institutions and knowledge systems, and increase the resilience of both mountain environments and their inhabitants. The key objectives of this chapter are to reflect upon the links between carbon retention and capture, the provision of other ecosystem services and livelihood impacts, consider the challenges in developing payment systems for carbon storage and outline the key forward-looking interdisciplinary and multi-stakeholder opportunities to advance progress towards pro-poor, climate-smart development in the mountainous regions of the HKH. These are among the measures that can be seen as opportunities.
