Numerous medical studies have shown the positive effects of forests on different aspects of human health. This study deals with the content of major terpenes in dominant coniferous species in Tara National Park, Serbia, in order to explore the potential for the development of a novel health tourism programme based on forest therapy. Main terpenes were analysed using a headspace-sam-pling technique coupled with gas-chromatography-mass spectrometry (Head-space-GC/MS). Nee-dles of fir and spruce growing in the vicinity of hiking trails were investigated for possibilities to perform such therapy. Major detected terpenes were α-cadinol and spathulenol previously de-scribed as antiviral, antitumor, antimicrobial and immunomodulatory agents. The results of the study were favourable and worked well with the existing walking infrastructure in the observed area of the Tara Mountain, as they act as invaluable resources for designing the structured forest bathing walks. The study not only adds to the knowledge in the environmental and public health realm but also to tourism and sustainability studies.

While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few ‘hyperdominant’species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing morecarbon than any other ecosystem on Earth. Here we ask, using a unique data set of 530 forest plots, if the functions of storing andproducing woody carbon are concentrated in a small number of tree species, whether the most abundant species also dominate carboncycling, and whether dominant species are characterized by specific functional traits.

Most beginning food forests face the following challenge: how do we get the harvest to the consumer? At food forest 't Mortelke they had the same question. The following research presents the answer to the following question: 'What are potential outlets for the harvest of Voedselbos 't Mortelke and how can these collaborations be realized?' The research provides more clarity on the needs of the market regarding potential collaborations with Voedselbos 't Mortelke. Interviews with interested parties (restaurants, country stores, organic supermarkets, individuals) revealed that the most appropriate form of cooperation with the food forest lies with fine-dining restaurants in the Eindhoven area. To initiate these collaborations an experimental phase is needed in which the chefs can get to know the products of the food forest. As a result of this research, several collaborations with restaurants have been initiated! Due to privacy reasons, certain parts of the research have been removed from the publication version.

Micro and macro algae are a rich source of lipids, proteins and carbohydrates, but also of secondary metabolites like phytosterols. Phytosterols have important health effects such as prevention of cardiovascular diseases. Global phytosterol market size was estimated at USD 709.7 million in 2019 and is expected to grow with a CAGR of 8.7% until 2027. Growing adoption of healthy lifestyle has bolstered demand for nutraceutical products. This is expected to be a major factor driving demand for phytosterols. Residues from algae are found in algae farming and processing, are found as beachings and are pruning residues from underwater Giant Kelp forests. Large amounts of brown seaweed beaches in the province of Zeeland and are discarded as waste. Pruning residues from Giant Kelp Forests harvests for the Namibian coast provide large amounts of biomass. ALGOL project considers all these biomass residues as raw material for added value creation. The ALGOL feasibility project will develop and evaluate green technologies for phytosterol extraction from algae biomass in a biocascading approach. Fucosterol is chosen because of its high added value, whereas lipids, protein and carbohydrates are lower in value and will hence be evaluated in follow-up projects. ALGOL will develop subcritical water, supercritical CO2 with modifiers and ethanol extraction technologies and compare these with conventional petroleum-based extractions and asses its technical, economic and environmental feasibility. Prototype nutraceutical/cosmeceutical products will be developed to demonstrate possible applications with fucosterol. A network of Dutch and African partners will supply micro and macro algae biomass, evaluate developed technologies and will prototype products with it, which are relevant to their own business interests. ALGOL project will create added value by taking a biocascading approach where first high-interest components are processed into high added value products as nutraceutical or cosmeceutical.

Indonesia’s peat forests remain severely threatened by forest fires, oil palm plantation development and extractive industries, which leads to biodiversity loss, increased emissions of greenhouse gases, and the marginalization of Indigenous Peoples and local communities. In 2008 the Government of Indonesia introduced the Social Forestry Programme under which Indigenous Peoples and local communities can acquire a 35-year management permit. Since then, about 10 percent of Indonesian State Forest has been designated for community-based forest conservation and restoration initiatives. The devolution of authority to the local level has created a new playing field. The Social Forestry Programme reverses more than a century of centralistic forest policy, and requires a fundamental re-orientation of all actors working in the forestry sector. The central question underlying this proposal is how Dutch civil society organizations (applied universities and NGOs) can effectively support Indigenous Peoples and local communities in the protection and restoration of peat forests in Indonesia. This project aims to set up a Living Lab in Ketapang District in West Kalimantan to study, identify and test novel ways to work together with a variety of stakeholders to effectively conserve and restore peat forest. In Ketapang District, Tropenbos Indonesia has assisted three Village Forest Management Groups (Pematang Gadung, Sungai Pelang and Sungai Besar) in securing a Social Forestry Permit. Students from three Dutch Universities (Van Hall Larenstein, Aeres Hogeschool and Inholland) will conduct research in partnership with students from Universitas Tanjungpura on the integration of local ecological knowledge and technical expertise, on the economic feasibility of community-based forestry enterprises, and on new polycentric governance structures. The results of these studies will be disseminated to policy makers and civil society groups working in Indonesia, using the extensive networks of IUCN NL and Tropenbos Indonesia.
