Comprehensive understanding of the merits of bottom-up urban development is lacking, thus hampering and complicating associated collaborative processes. Therefore, and given the assumed relevancies, we mapped the social, environmental and economic values generated by bottom-up developments in two Dutch urban areas, using theory-based evaluation principles. These evaluations raised insights into the values, beneficiaries and path dependencies between successive values, confirming the assumed effect of placemaking accelerating further spatial developments. It also revealed broader impacts of bottom-up endeavors, such as influences on local policies and innovations in urban development.

Purpose: The purpose of this study is to find determinants about risk resilience and develop a new risk resilience approach for (agricultural) enterprises. This approach creates the ability to respond resiliently to major environmental challenges and changes in the short term and adjust the management of the organization, and to learn and transform to adapt to the new environment in the long term while creating multiple value creation. Design/methodology: The authors present a new risk resilience approach for multiple value creation of (agricultural) enterprises, which consists of a main process starting with strategy design, followed by an environmental analysis, stakeholder collaboration, implement ESG goals, defining risk expose & response options, and report, learn & evaluate. In each step the organizational perspective, as well as the value chain/area perspective is considered and aligned. The authors have used focus groups and analysed literature from and outside the field of finance and accounting, to design this new approach. Findings: Researchers propose a new risk resilience approach for (agricultural) enterprises, based on a narrative about transforming to multiple value creation, founded determinants of risk resilience, competitive advantage and agricultural resilience. Originality and value: This study contributes by conceptualizing risk resilience for (agricultural) enterprises, by looking through a lens of multiple value creation in a dynamic context and based on insights from different fields, actual ESG knowledge, and determinants for risk resilience, competitive advantage and agricultural resilience.
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.

The seaweed aquaculture sector, aimed at cultivation of macroalgal biomass to be converted into commercial applications, can be placed within a sustainable and circular economy framework. This bio-based sector has the potential to aid the European Union meet multiple EU Bioeconomy Strategy, EU Green Deal and Blue Growth Strategy objectives. Seaweeds play a crucial ecological role within the marine environment and provide several ecosystem services, from the take up of excess nutrients from surrounding seawater to oxygen production and potentially carbon sequestration. Sea lettuce, Ulva spp., is a green seaweed, growing wild in the Atlantic Ocean and North Sea. Sea lettuce has a high nutritional value and is a promising source for food, animal feed, cosmetics and more. Sea lettuce, when produced in controlled conditions like aquaculture, can supplement our diet with healthy and safe proteins, fibres and vitamins. However, at this moment, Sea lettuce is hardly exploited as resource because of its unfamiliarity but also lack of knowledge about its growth cycle, its interaction with microbiota and eventually, possible applications. Even, it is unknown which Ulva species are available for aquaculture (algaculture) and how these species can contribute to a sustainable aquaculture biomass production. The AQULVA project aims to investigate which Ulva species are available in the North Sea and Wadden Sea which can be utilised in onshore aquaculture production. Modern genomic, microbiomic and metabolomic profiling techniques alongside ecophysiological production research must reveal suitable Ulva selections with high nutritional value for sustainable onshore biomass production. Selected Ulva spp lines will be used for production of healthy and safe foods, anti-aging cosmetics and added value animal feed supplements for dairy farming. This applied research is in cooperation with a network of SME’s, Research Institutes and Universities of Applied Science and is liaised with EU initiatives like the EU-COST action “SeaWheat”.
