Urban Green Space (UGS) is considered to be beneficial for health and wellbeing of urban residents. But there is growing evidence that benefits are not equally distributed. In this article we aim to understand the role that UGS plays in the process of social exclusion and the role urban greening strategies can play in enhancing social equity for specific groups that are excluded: elderly people with dementia, people with mental issues and people from an underprivileged neighborhood. The concepts of inclusion and exclusion and their relation to UGS are discussed. Four exclusion mechanisms are distinguished based on the role of the physical and societal environment and on the role of actors involved (public or private). Further, we identify four discourses behind possible strategies and measures to promote inclusion. These mechanisms and discourses are confronted with an analysis of three cases promoting inclusion of elderly with dementia, people with mental health issues and people from an underprivileged neighborhood. Succesful inclusion strategies in these cases are based on alignment between private actors initiatives and public actions. The cases indicate that public and private actors need to cooperate better in order to make UGS part of inclusion strategies.

Pesticides applied to soil surface are subject to photodegradation if the parent molecule is sensitive to UV-light absorption. Photodegradation studies are therefore mandatory for the registration of plant protection products to provide data on the degradation rate and on the nature of photoproducts formed. In general, sunlight is simulated in these studies with xenon lamps, e.g., a Suntest® device. Surface application on very thin soil layers followed by direct irradiation is common practice, but the control of the boundary conditions, i.e. soil temperature and moisture, to maintain the structure and viability of the soil is challenging. A homogeneous and stable soil microclimate is crucial to compare the degradation data of the test item from the irradiated soil samples to the dark controls as well as to the results from the aerobic soil metabolism study. After trying different scale-up test systems with the UV-sensitive herbicide imazamox as comparative test item, a new soil photolysis test system was developed which is manageable in the laboratory and enables a more favorable management of the boundary conditions, especially with regard to the soil moisture and temperature. For this, the solar simulator SolarConstant® 1200, equipped with metal halide lamps Radium HRI-TS 1000W/D/S/PRO, was installed by Atlas Ametek (Germany) in a temperature controllable walk-in incubation chamber with aluminum racks and reflectors to minimize diffuse light and to maintain a homogenous temperature of 22(± 1)°C within the irradiated soil. Borosilicate glass vessels with an inner diameter of 10 cm and a maximum height of 9 cm, covered by quartz glass, were used for the incubation of the applied soil under light. Contrary to the imazamox degradation half-lives obtained with the Suntest® test system, where an unusual slower degradation was observed under light compared to the dark controls, the results from the new SolarConstant® study design showed the expected faster degradation under light. Hence, it can be concluded that the experimental boundary conditions of the new test system are more suitable to maintain the viablity of the irradiated soil. Since no adjustments of the soil water content were needed, compared to daily water adjustments for thin soil layers incubated under a Suntest®, drying–wetting cycles are eliminated and microbial-induced soil processes are maintained.

Background: This 4-year research project focuses on 6 social community enterprises (SCEs) that operate in 5 neighborhoods in a Dutch city. Residents of these neighborhoods face problems such as poor average levels of physical and mental health, high unemployment rates, and weak social cohesion. SCEs offer residents social, cultural, and work-related activities and are therefore believed to help these persons develop themselves and strengthen the social ties in the community. Because of a lack of empirical evidence; however, it is unclear whether and how SCEs benefit the health and well-being of participants. Objective: This paper outlines a protocol for an evaluation study on the impact of SCEs, aiming to determine (1) to what extent SCEs affect health and well-being of participating residents, (2) what underlying processes and mechanisms can explain such impact, and (3) what assets are available to SCEs and how they can successfully mobilize these assets. Methods: A mixed methods multiple-case study design including repeated measurements will be conducted. Six SCEs form the cases. An integrated model of SCE health intervention will be used as the theoretical basis. First, the impact of SCEs is measured on the individual and community level, using questionnaires and in-depth interviews conducted with participants. Second, the research focuses on the underlying processes and mechanisms and the organizational and sociopolitical factors that influence the success or failure of these enterprises in affecting the health and well-being of residents. At this organizational level, in-depth interviews are completed with SCE initiators and stakeholders, such as municipal district managers. Finally, structurally documented observations are made on the organizational and sociopolitical context of the SCEs. Results: This research project received funding from the Netherlands Organization for Health Research and Development in 2018. Data collection takes place from 2018 until 2022. Data analysis starts after the last round of data collection in 2022 and finalizes in 2024. Expected results will be published in 2023 and 2024. Conclusions: Despite the societal relevance of SCEs, little empirical research has been performed on their functioning and impact. This research applies a variety of methods and includes the perspectives of multiple stakeholders aiming to generate new empirical evidence. The results will enable us to describe how SCE activities influence intermediate and long-term health outcomes and how the organizational and sociopolitical context of SCEs may shape opportunities or barriers for health promotion. As the number of these initiatives in the Netherlands is increasing rapidly, this research can benefit many SCEs attempting to become more effective and increase their impact. The findings of this research will be shared directly with relevant stakeholders through local and national meetings and annual reports and disseminated among other researchers through scientific publications.

This paper describes the development of care farming in the Netherlands, one of the pioneering countries in this sector, where care farming has developed into a very diverse sector, with some farmers focussing primarily on agricultural production and others more specifically on providing care services. Care farms are increasingly open to a diversity of participants. The sector has become professionalised with the establishment of strong regional organisations and a steady growth increase in revenues, providing employment opportunities and boosting the economy of rural areas. In this paper, we highlight two promising innovations in care farming: education for school dropouts and the establishment of social farming activities in cities. These innovations face the challenge of connecting not only the agricultural and care sectors, but also the educational sector and the urban context. Initiators face a number of challenges, like trying to embed their activities in the educational sector, a mismatch in regulations and a lack of legitimacy in the case of education on care farms, as well as problems gaining access to land and a lack of recognition in the case of social farming in urban areas. However, the prospects are promising in both cases, because they match the changing demands in Dutch society and are able to integrate social, ecological and economic benefits.

Background: Local health and social care partnerships that stimulate community engagement of vulnerable populations are promising for health promotion. In the Netherlands, some of these partnerships include in addition to stakeholders from the health and social care sector, also stakeholders from the green, agricultural and voluntary sector. Examples are green care farms, farms that combine agricultural activities with social care and support services, e.g. day services for people with dementia and supported workplaces for vulnerable populations such as vulnerable youth and people with mental health problems or intellectual disabilities. Clients, or participants in the vocabulary of care farmers, are involved in agricultural production and farm-related activities. In addition to these initiatives in rural areas, an increasing number of green social care services is developed in urban settings. Examples are community gardens, green enterprises and urban farms. These initiatives are embraced by many municipalities because they aim to empower vulnerable populations and stimulate social participation. They are characterized by meaningful activities with plants and animals and an informal open atmosphere facilitated by a person-centred approach of the professionals and volunteers involved. Initiators of the green social care services design these services in collaboration with stakeholders such as participants, professionals and volunteers involved in the initiative and/or the community.During the last decade, researchers, farmers, social entrepreneurs, care organizations and municipalities collaborated to get a better understanding of the experiences with and impact of these green urban and rural initiatives. Although the initiatives are promising, they face many challenges and more knowledge is needed about their reach and impact and on individuals, communities and organizations.Aims and objectives: The aims of our workshop are to: 1. give an overview of the different types of green rural and urban initiatives, and how vulnerable citizens and communities are empowered and engaged respectively within these initiatives and 2. share the lessons learned from the different initiatives so far, e.g. the major obstacles for collaboration, how innovative initiatives gain legitimacy and access to funding and what conventional social care providers can learn from these initiatives.Format: During this session, we will present findings of different research projects on green care farms and green urban and initiatives offering services such as rehabilitation of different groups of vulnerable citizens and adult day services for people with dementia. Initiators of different types of initiatives will present their experiences and main challenges. After that, we will discuss the following topics with the audience: 1. What is the value of these initiatives?; 2. What is necessary to increase their impact and tackle challenges they are facing? and 3. To what extent is it feasible to implement such initiatives in other countries?Target audience: The workshop is targeted at researchers, policy-makers and practitioners who want to know more about innovative initiatives such as green social care services.Learnings: Participants obtain insight in green social care initiatives and their potential impact on wellbeing, participation and empowerment of different vulnerable populations. They will have learned about challenges initiators are facing and how these may be solved.

It is often challenging to establish a good relationship between the green initiatives of urban citizens and local governments. Our aim is to gain a better understanding of how citizens and local authorities interact and how they can establish good relationships, relationships that contribute to the realization of the aims and interests of citizen initiatives and local governments. We analysed these relationships for five different initiatives, including the perspectives of initiators and civil servants. We hypothesized that an important challenge is to connect the initiative's informal world and the formal world of local governments. Relationships can be problematic due to a lack of recognition and appreciation for the initiators on the part of the municipality, diverging ambitions or ideologies between the initiative and municipality or unreliable behaviour of initiatives in the view of civil servants. The results showed that a willingness to work together and developing trust are key conditions in developing good partnerships. Our study provide insight into how mutual trust can be developed. Developing a trustful relationship requires social competences. Trust building involves several social practices: establishing an emotional connection, ability and integrity, and aligning to each other's expectations. Formal aspects of local governments, like rules and procedures, are not a major problem in the development of initiatives when a trustful relationship has been established. The civil servants and aldermen (City Council Members) involved are then able to overcome formal obstacles, such as mismatch with regulations.

Nature-based adult day services (ADSs) in urban areas are relatively new services in the Netherlands. Since knowledge about these services is still scarce, this study aimed to elucidate their value for people with dementia and their family carers in terms of health and wellbeing. We interviewed 39 people with dementia attending nature-based ADSs in urban areas and their family carers, and 17 providers of these services. Respondents indicated that nature-based ADSs in urban areas positively affected the health and wellbeing of people with dementia. According to them, these services support contact with nature and animals, activity engagement, physical activity, structure, social interactions, healthy eating, a sense of meaning in life and a focus on normal daily life. Respondents further indicated that these services stimulate respite, reassurance and maintenance of family carers’ own activities and social contacts. We conclude that nature-based ADSs in urban areas have a wide range of benefits that might affect the health and wellbeing of people with dementia and their family carers. Worldwide, demand is growing for innovative practices in dementia care. It is therefore worthwhile monitoring the development of dementia care innovations, such as nature-based ADSs, and for countries to exchange lessons learned from these services.

Although it has been recognized that the adsorption of organics to clay and silt particles is an important determinant of the stability of organic matter in soils, no attempts have been made to quantify the amounts of C and N that can be preserved in this way in different soils. Our hypothesis is that the amounts of C and N that can be associated with clay and silt particles is limited. This study quantifies the relationships between soil texture and the maximum amounts of C and N that can be preserved in the soil by their association with clay and silt particles. To estimate the maximum amounts of C and N that can be associated with clay and silt particles we compared the amounts of clay-and silt-associated C and N in Dutch grassland soils with corresponding Dutch arable soils. Secondly, we compared the amounts of clay-and silt-associated C and N in the Dutch soils with clay and silt-associated C and N in uncultivated soils of temperate and tropical regions. We observed that although the Dutch arable soils contained less C and N than the corresponding grassland soils, the amounts of C and N associated with clay and silt particles was the same indicating that the amounts of C and N that can become associated with this fraction had reached a maximum. We also observed close positive relationships between the proportion of primary particles < 20 µm in a soil and the amounts of C and N that were associated with this fraction in the top 10 cm of soils from both temperate and tropical regions. The observed relationships were assumed to estimate the capacity of a soil to preserve C and N by their association with clay and silt particles. The observed relationships did not seem to be affected by the dominant type of clay mineral. The only exception were Australian soils, which had on average more than two times lower amounts of C and N associated with clay and silt particles than other soils. This was probably due to the combination of low precipitation and high temperature leading to low inputs of organic C and N. The amount of C and N in the fraction > 20 µm was not correlated with soil texture. Cultivation decreased the amount of C and N in the fraction > 20 µm to a greater extent than in the fraction < 20 µm, indicating that C and N associated with the fraction < 20 µm is better protected against decomposition. The finding of a given soil having a maximum capacity to preserve organic C and N will improve our estimations of the amounts of C and N that can become stabilized in soils. It has important consequences for the contribution of different soils to serve as a sink or source for C and N in the long term.

BackgroundOECD TG 309 “Aerobic Mineralisation in Surface Water” (OECD Test Guideline 309 (2004)) is currently used in regulation for the assessment of the persistence of chemicals in surface water. The test is performed in a batch under defined conditions. Processes which might be relevant for the fate of a chemical in surface water like direct and indirect photolysis are not addressed. In order to study the impact of sunlight on the fate in surface water, pendimethalin, a herbicidal active substance with known sensitivity to aqueous photolysis, was used. This was tested in an experiment based on OECD 309, but scaled up to 900 L size with a 1.40 m water column and irradiated with special lamps in order to monitor the fate of the substance at different water depths, in comparison to dark controls.ResultsPendimethalin degraded significantly under the applied test conditions. The test setups with exposure to simulated sunlight showed a significant faster degradation compared to the dark experiments. Application of 900 g sediment (1% of test system) to the test system further increased the degradation rate. In the simulated sunlight setups a faster degradation was observed in the upper water layer, hence, the concentration of the photolysis products were highest in the upper water layer, where the highest light intensity was measured. With decreasing light intensity in deeper water layers photolysis products were still detected at a water depth of 125 cm. Mineralisation up to 22% of the applied radioactivity was observed. In the dark controls neither significant amounts of photolysis products nor any mineralisation were detected. Among the different sampling depths no significant differences were observed. It was further observed that the dark controls became anaerobic at the end of the incubation time. This has been observed previously in standard laboratory tests according to OECD 309.ConclusionsThe study proves that for a substance sensitive to photolysis like pendimethalin, exposure to simulated sunlight leads to a significantly reduced degradation half-life (DegT50) in surface water compared to the dark control. In the standard test according to OECD guideline 309 the influence of photolytical degradation is not considered and thus the laboratory test can lead to the overestimation of the persistence of a chemical in surface water and consequently to a false-positive evaluation in the overall PBT assessment (ECHA Guidance on Information Requirements and Chemical Safety Assessment 2004), when only the results of the standard OECD 309 study are considered.

Purpose: Care farming is an underexplored example of agricultural diversification. In their process of diversification, care farmers are newcomers to the healthcare sector, facing high entry barriers and lacking the skills required to build a solid and legitimate presence in this new domain. Changes in the care regime have provided opportunities for new players, like regional organizations of care farmers, to gain access to care budgets. The purpose of this paper is to describe and analyze how strategies designed to establish regional organizations of care farms with similar access to institutional resources unfold and are translated into entrepreneurial behavior, organizational identity and legitimacy, and help provide access to care budgets. Design/methodology/approach: Using entrepreneurship, identity formation and legitimacy building as guiding concepts, the authors interviewed stakeholders and analyzed activities and documents to gain a broad perspective with regard to the organizations, skills and activities. Findings: The authors identified two types of regional care farm organizations: a cooperative and a corporate type. While the corporate type clearly exhibited entrepreneurial behavior, leading to a trustful and appealing organizational identity, substantial fund-raising and an early manifestation of institutional and innovative legitimacy in the care sector, the cooperative type initially lacked entrepreneurial agency, which in turn led to a lack of legitimacy and a slow development toward a more professional market-oriented organization. Manifesting entrepreneurial behavior and strategically aligning the healthcare and agricultural sectors, and building up both institutional and innovative legitimacy in the care sector proved to be crucial to the successful development of regional organizations of care farms. This study contributes to existing literature by exploring relationships between entrepreneurial and institutional strategies, legitimacy, organizational identity and logics. Originality/value: This study contributes to the literature by exploring how in times with changes in institutional logics, strategies to establish new organizations unfold. The authors have shown how differences in strategy to establish new organizations with similar access to institutional resources unfold and are translated into diverging organizational identities and degrees of legitimacy. Entrepreneurial behavior is the key to create a trustful and appealing identity and innovative and institutional legitimacy which is important for providing access to an institutionalized sector.
