Biodiversity preservation is often viewed in utilitarian terms that render non-human species as ecosystem services or natural resources. The economic capture approach may be inadequate in addressing biodiversity loss because extinction of some species could conceivably come to pass without jeopardizing the survival of the humans. People might be materially sustained by a technological biora made to yield services and products required for human life. The failure to address biodiversity loss calls for an exploration of alternative paradigms. It is proposed that the failure to address biodiversity loss stems from the fact that ecocentric value holders are politically marginalized and underrepresented in the most powerful strata of society. While anthropocentric concerns with environment and private expressions of biophilia are acceptable in the wider society, the more pronounced publicly expressed deep ecology position is discouraged. “Radical environmentalists” are among the least understood of all contemporary opposition movements, not only in tactical terms, but also ethically. The article argues in favor of the inclusion of deep ecology perspective as an alternative to the current anthropocentric paradigm. https://doi.org/10.1080/1943815X.2012.742914 https://www.linkedin.com/in/helenkopnina/
Agrobiodiversity has been decreasing substantially in Europe. Social scientific research in this area has paid limited attention to how citizens value agrobiodiversity and its decline, and how these valuations can be influenced. We explore the influence of different arguments for enhancing agro-biodiversity, delivered via short movies, on attitudes and behaviour of students, environmental professionals and people interested in nature conservation in the Netherlands. We conclude that information provision does not influence attitudes. However, it does influence values assigned to agrobiodiversity, but not always in the ways we hypothesized. Information about the intrinsic value of agrobiodiversity has the most effects on values assigned to agrobiodiversity. Among students, women and people with a low emotional attachment with agricultural landscapes (‘place identity’ and ‘place dependence’), emphasizing the instrumental value of agrobiodiversity has a counter-intuitive effect. It does not influence the importance of this value but instead reinforces the intrinsic value they assign to agrobiodiversity. The latter finding is at odds with the instrumental biodiversity discourse in science and policy, which, under headings such as ecosystem services and natural capital, aims to mobilize support for nature conservation by emphasizing its instrumental, functional and economic values. Emphasizing the intrinsic value of agrobiodiversity seems more effective.
We have developed a lesson in which learners interactively construct a qualitative representation about climate change and the decline of biodiversity by using the online software DynaLearn. They are supported by a built-in support function to notice mistakes, and they can run simulations to explore system behavior. Throughout the lesson, learners are guided by a workbook providing necessary information step by step.
Many Caribbean reefs have shifted from coral-dominated to algal-dominated ecosystems. The high algae cover reduces coral recruitment, making the reef unable to recover from other disturbances and resulting in flatter reefs with lower biodiversity. One of the reasons for the proliferation of algae is a mass die-off of the herbivorous sea urchin Diadema antillarum in the early 1980s. Natural recovery of Diadema populations is slow to non-existent, making active restoration of this important grazer a top priority in Caribbean coral reef management, especially since Diadema densities were reduced by another mass mortality event in 2022. The marine park organizations of Saba and St. Eustatius want to restore Diadema populations by restocking cultured individuals. However, important knowledge gaps need to be addressed before large numbers of Diadema can be restocked on the reef. Current culture methods can only produce a limited number of competent larvae. In addition, only 8% of the settlers survive and after restocking, survival on the reef is low as well. In the RAAK PRO Diadema II project, the bottlenecks in Diadema culture will be addressed by comparing larval survival across multiple culture methods and investigating the relation between larval size and post-settlement survival. Growing-out juveniles at sea is likely to help prepare them for life in the wild, while restocking at an optimal size might also increase survival. Finally, a thorough restocking site selection based on high shelter availability and settlement rates will increase the long-term Diadema densities. The acquired knowledge and developed practices will be verified in a larger scale restocking experiment involving at least 5000 Diadema urchins. By restoring Diadema populations through restocking, macroalgae will be more intensively removed and corals will have a chance to settle and to survive, increasing the ability of the reef to cope with other stressors.
Historical sites, specifically former military fortifications, are often repurposed for tourism and recreation. While some of over 100 Dutch forts are recognized as UNESCO World Heritage sites, a substantial number are currently underdeveloped, putting their heritage value and biodiversity at risk. This demands action, as forts are well-positioned to relieve overtourism in other locations, responding to the Netherlands Board of Tourism and Convention's call to spread visitors to lesser-known areas. Furthermore, developing lesser-known fort sites could provide tourism and recreation opportunities near populated areas, thus contributing to the well-being not only of visitors but also the environment. Development initiatives depend on a transition from isolation to cooperation across sites. However, for cooperation to be effective, enterprises and agencies managing these forts still lack data regarding visitor expectations and experiences. We will employ a multidisciplinary approach to capturing visitor demographics, motivations, and experiences, through conducting quantitative questionnaires, lab-driven physiological experience measurement, and location tracking. This proposal builds on the previous project, “Experiencing Nature”, funded by Centre of Expertise in Leisure, Tourism, and Hospitality, which utilized Breda Experience Lab technologies to explore visitor experiences at Fort de Roovere. In sum, the purpose of the present project is to measure and analyze visitor demographics, motivations, and experiences at less-developed forts, and to develop a toolkit to inspire, support, and monitor development of these forts for heritage preservation, visitor experience, and biodiversity. The project will be conducted in collaboration with Flemish partners, thereby forming the consortium comprised of the Alliantie ZuiderWaterlinie (NL), Regionale Landschappen (VL), and Agentschap Natuur en Bos (VL), with support from municipalities in both countries. The project will promote regional synergies and facilitate long-lasting cross-border collaboration, especially toward coming Interreg EU proposals, whilst informing the design of interregional marketing campaigns and supporting planning for visitor flows and biodiversity conservation efforts.

Human kind has a major impact on the state of life on Earth, mainly caused by habitat destruction, fragmentation and pollution related to agricultural land use and industrialization. Biodiversity is dominated by insects (~50%). Insects are vital for ecosystems through ecosystem engineering and controlling properties, such as soil formation and nutrient cycling, pollination, and in food webs as prey or controlling predator or parasite. Reducing insect diversity reduces resilience of ecosystems and increases risks of non-performance in soil fertility, pollination and pest suppression. Insects are under threat. Worldwide 41 % of insect species are in decline, 33% species threatened with extinction, and a co-occurring insect biomass loss of 2.5% per year. In Germany, insect biomass in natural areas surrounded by agriculture was reduced by 76% in 27 years. Nature inclusive agriculture and agri-environmental schemes aim to mitigate these kinds of effects. Protection measures need success indicators. Insects are excellent for biodiversity assessments, even with small landscape adaptations. Measuring insect biodiversity however is not easy. We aim to use new automated recognition techniques by machine learning with neural networks, to produce algorithms for fast and insightful insect diversity indexes. Biodiversity can be measured by indicative species (groups). We use three groups: 1) Carabid beetles (are top predators); 2) Moths (relation with host plants); 3) Flying insects (multiple functions in ecosystems, e.g. parasitism). The project wants to design user-friendly farmer/citizen science biodiversity measurements with machine learning, and use these in comparative research in 3 real life cases as proof of concept: 1) effects of agriculture on insects in hedgerows, 2) effects of different commercial crop production systems on insects, 3) effects of flower richness in crops and grassland on insects, all measured with natural reference situations
