The increasing demand for Prunus africana resources is an opportunity for its conservation and commercial use to support livelihoods in Africa. The objective for this study was to investigate major steps to advance production of P. africana for long-term commercial use in Uganda. Specific objectives were to explore potential production schemes, setbacks in production and strategies to advance it. The study was done by review of literature, documents and interviews with experts. Results indicated Agroforestry and large plantations to be useful schemes for production. Identified setbacks are: low trade in P. africana, unknown returns from production, competing land uses, long growth period, limited market assurance and information. The lack of a resource assessment for P. africana in forests contributes to its low trade which undermines related economic benefits for national development and incentives to commercial production. We propose that a national Quantitative resource assessment of P. africana in forests is one of the crucial steps that should be undertaken to carefully organise and advance sustainable trade to provide rational incentives for commercial production. Subsequently, production should be localised in suitable sites and producers be organised into cooperatives. Further research to improve returns from commercial production of P. africana is needed.

Careers work is a very political business. Since the early 1990s, successive governments in England and the Netherlands have persistently challenged those working in the careers sector to demonstrate the educational, social and economic value and impact of their work. In this context, the marketisation of career guidance policies and practices has expanded, with a growing assumption that market-based goods and services ensure greater responsiveness to consumer choice and offer better and/or more innovative services for lower prices. In this article, we do not intend to give a comparison of trends in England and the Netherlands. We only examine the impact of market principles applied to career guidance provision in both countries. Findings indicate such provision for young people is on a steady decline. Lessons learned from these two nations indicate that a market for quality career services does not exist in schools and colleges. As a result, marketisation and privatisation of career services have led to an impoverished and fragmented supply of services. Greater attention by governments in career guidance policies for young people (and adults) is necessary to reduce the widening gap between ‘the haves and have nots’ in society. Failure to reduce labour market mismatch through new forms of careers dialogue is not only damaging and costly for individuals, families and employers, but for the taxpayer too.
Climate change and changing land use challenge the livability and flood safety of Dutch cities. One option cities have to become more climate-proof is to increase infiltration of stormwater into soil through permeable pavement and thus reduce discharge of stormwater into sewer systems. To analyze the market receptivity for permeable pavements in the Netherlands, this article focuses on the perception of end-users towards key transition factors in the infrastructure transformation processes. Market receptivity was studied on two levels: (1) on the system level, by analyzing 20 key factors in the Dutch urban water sector that enable wider application of permeable pavements; and (2) on the technology level, by analyzing 12 key factors that explain why decision makers select permeable pavements or not. Results show that trust between cooperating partners was perceived as the system level key factor that needs to be improved most to facilitate the wider uptake of permeable pavements. Additionally, the association of end-users with permeable pavement, particularly their willingness to apply these technologies and their understanding of what kinds of benefits these technologies could bring, was regarded the most important receptivity attribute. On the technology level, the reliability of permeable pavement was regarded as the most important end-user consideration for selecting this technology.
Chemical preservation is an important process that prevents foods, personal care products, woods and household products, such as paints and coatings, from undesirable change or decomposition by microbial growth. To date, many different chemical preservatives are commercially available, but they are also associated with health threats and severe negative environmental impact. The demand for novel, safe, and green chemical preservatives is growing, and this process is further accelerated by the European Green Deal. It is expected that by the year of 2050 (or even as soon as 2035), all preservatives that do not meet the ‘safe-by-design’ and ‘biodegradability’ criteria are banned from production and use. To meet these European goals, there is a large need for the development of green, circular, and bio-degradable antimicrobial compounds that can serve as alternatives for the currently available biocidals/ preservatives. Anthocyanins, derived from fruits and flowers, meet these sustainability goals. Furthermore, preliminary research at the Hanze University of Applied Science has confirmed the antimicrobial efficacy of rose and tulip anthocyanin extracts against an array of microbial species. Therefore, these molecules have the potential to serve as novel, sustainable chemical preservatives. In the current project we develop a strategy consisting of fractionation and state-of-the-art characterization methods of individual anthocyanins and subsequent in vitro screening to identify anthocyanin-molecules with potent antimicrobial efficacy for application in paints, coatings and other products. To our knowledge this is the first attempt that combines in-depth chemical characterization of individual anthocyanins in relation to their antimicrobial efficacy. Once developed, this strategy will allow us to single out anthocyanin molecules with antimicrobial properties and give us insight in structure-activity relations of individual anthocyanins. Our approach is the first step towards the development of anthocyanin molecules as novel, circular and biodegradable non-toxic plant-based preservatives.
Plastic products are currently been critically reviewed due to the growing awareness on the related problems, such as the “plastic soup”. EU has introduced a ban for a number of single-use consumer products and fossil-based polymers coming in force in 2021. The list of banned products are expected to be extended, for example for single-use, non-compostable plastics in horticulture and agriculture. Therefore, it is crucial to develop sustainable, biodegradable alternatives. A significant amount of research has been performed on biobased polymers. However, plastics are made from a polymer mixed with other materials, additives, which are essential for the plastics production and performance. Development of biodegradable solutions for these additives is lacking, but is urgently needed. Biocarbon (Biochar), is a high-carbon, fine-grained residue that is produced through pyrolysis processes. This natural product is currently used to produce energy, but the recent research indicate that it has a great potential in enhancing biopolymer properties. The biocarbon-biopolymer composite could provide a much needed fully biodegradable solution. This would be especially interesting in agricultural and horticultural applications, since biocarbon has been found to be effective at retaining water and water-soluble nutrients and to increase micro-organism activity in soil. Biocarbon-biocomposite may also be used for other markets, where biodegradability is essential, including packaging and disposable consumer articles. The BioADD consortium consists of 9 industrial partners, a branch organization and 3 research partners. The partner companies form a complementary team, including biomass providers, pyrolysis technology manufacturers and companies producing products to the relevant markets of horticulture, agriculture and packaging. For each of the companies the successful result from the project will lead to concrete business opportunities. The support of Avans, University of Groningen and Eindhoven University of Technology is essential in developing the know-how and the first product development making the innovation possible.
This pre-study anticipates to a SIA call focussing on circular and bio-based economy in Brazil. It is linked to the Living Lab Brazil managed by Avans University of Applied Sciences. Although the dairy value chain will benefit from both circular and bio-based principles, this pre-study will be limited to circular systems. There is a vast potential for investment by the Dutch and Brazilian private sector in the dairy value chain in Minas Gerais (MG), Brazil. There is also ample room to improve production efficiency towards a more circular system. Notwithstanding the business opportunities in the Brazilian dairy sector, there are challenges in attracting and consolidating partnerships along the circular-based value chain. A better understanding of the demands, challenges and opportunities of the interested Dutch companies is highly relevant to develop sustainable circular-based dairy value chains. Therefore, the goal of our project proposal is the exploration of a potential Dutch business network that is interested to invest in the Brazilian circular dairy value chain, and an exploration of the potential business opportunities for the Dutch and Brazilian dairy sector. The consortium in our proposal is conformed as follows: (a) Van Hall Larenstein University of Applied Sciences (VHL). VHL is the leading knowledge institute. Vilentum University of Applied Sciences and the Federal University of Viçosa will participate through VHL. (b) Alta Genetics BV; (c) Groasis BV. To achieve our goal we focus on the following questions: What is the potential and what are the bottlenecks for the Dutch private sector (SME’s) to increase business opportunities in the dairy sector of MG? What are the business opportunities to develop and innovate circular-based dairy value chains through the Dutch and Brazilian private sector with dairy breeding and agro-silvopastoral farming as pilots? The outputs of this study will be: A list of potential Dutch private investors, both interested but hesitating and/or already successful. Basically we would like to identify “partners” and to build up a business network where we could match-make the Dutch companies with the Brazilian companies or clients; A pre-proposal including intentions for further collaboration; Three detailed reports with marketing and investment opportunities and/or research strategy in relation to circular-based economy in: general dairy chain, dairy breeding and agro-silvopastoral farming. The latter two topics must be considered as pilots for the entire dairy value chain.
