Professional biography

Dr Yoseph Araya, is a Senior Lecturer in Ecology & Environmental Sciences within the Ecosystems and Biodiversity Research discipline. 

Contact: Yoseph [dot] Araya [at] open [dot] ac [dot] uk

Research interests

My particular research interest is in the functional relationships between plants and their environment (particularly water and nutrients). I especially enjoy integrating experimental studies with field investigations. I also am an enthusiastic communicator of science and environmental education.

Some projects I have been involved include:

  • Soil Moisture gradients and biodiversity in the Cape Flora, Western Cape, South Africa: looking at niche segregation, plant coexistence, ecohydrological management, evolution of plant diversity; as well as plant and soil micobial diversity relationships e.g. UK, Spain

  • Environmental education for the public and engagement in science, including Citizen Science on water, plants, hedges ... e.g. iSpot and in more formal way paraecologists

  • Quantitative Ecology i.e. querying plant record databases for trends and also collaborating with statisticians to test new methods e.g. Foodplain Meadows management

  • Valuing of Ecosystem Services for multiple purposes and stakeholders for sustainable wholistic environmental management - as part of wholistic evaluation

  • ​Macadamia tree growth and nut production in response to provenance, agroclimatic zone and management practices with Neno Macadamia Trust and Emmanuel Zuza Jr. Here is an excellent outreach video with Emmanuel describing an aspect of his project (https://youtu.be/3dlPDRtJuvc).

  • Microplastics in soil is a project looking at their fate and impact in the environment, working with Joanna Jesionkowska, Pallavi Anand  and collaborators in Severn Trent Water.

  • Habitat fragementation and butterfly conservation in urban ecosystems with Bradley Neal, Phil Wheeler and collaborators in MK Parks Trust.

Teaching interests

Prior to my role as a central academic, I have been an Associate Lecturer with the OU for a number of years, on various science, ecology and environmental science modules (from undergraduate to postgraduate) across faculties. I teach online, face-to-face and in the field, in addition to supporting research students. I particuarly enjoy modules that bridge across disciplines and involve approaches in technology-enhanced learning.

Some modules i have been involved are: Environmental Science (S206/SXF206), Biology of Survival (S295), Environmental Management (T219), Journey's in a changing Environment (U116), SXE390 (Science Project - Environment strand), Environment responding to change (SDT306). A free taster for SDT306 is entitled as 'Eating for the Environment'.

I write public education blogs at OU's OpenLearn website.

Impact and engagement

I have been priviledged to be an academic consultant and contribute to an OU-BBC production of Green Planet, a 5 episode exploration of how plants survive and support our earth. There is a dedicated website with poster and other articles, with my colleagues Prof. David Gowing and Dr Julia Cooke here: https://connect.open.ac.uk/greenplanet/

One of the meet the team discussion we had at Northern Ireland's Science Festival is available here: The Power of Plants Event - YouTube

I also participate in mentoring programmes for underrepresented groups with British Ecological Society, Institute for Environmental Science and more recently with the Equator Mentoring Network (funded by NERC).

Another recent project is Walking the Talk (with Dr Marcus Badger, Prof. Clare Warren and others) which aims to understand and encourage outdoor engagement of underrepresented groups.

I am involved in the role of public parks for public health and aging well with Dr Jitka Vseteckova and MK Parks Trust (https://www.keepmewalking.info/) and The Parks Trust podcats.

In summer 2022 I coordinated a couple of web workshops on Art-based global sustainbility education with Dr Maria Nita and citizen science training (upskilling) for employment with British Ecological Society.

External collaborations

I have active collaborations with colleagues in other institutions within the UK as well as overseas e.g. Spain, Germany, Malawi, and South Africa.

I am an active and passionate member of our professional body, British Ecological Society and its special interest group of Ecology Teaching and Learning as well as public engagement. 

I am a Fellow of the Higher Education Academy.

I am a trustee of a local NGO: Teach, Learn, Connect (UK registered).

I am in the advisory board for a citizen science project (South Africa).

I am in the editorial board for Biofuels, Bioproducts and Biorefining, Carbon Management and Plant Conservation.

We will work with a grassroots ethnic minority walking organisation to co-design walking routes that showcase aspects of the geological, landscape and ecological evolution of their local area that specifically link to OU research. This will: • Improve visibility of EES (and EES careers) within diverse communities who are under-represented in EES research • Engage these communities in cutting-edge EES from the Open University • Encourage confidence in walk leaders to communicate the science of the environment to their walk participants. • Train Earth/environmental scientists in mixed-methods approaches to public engagement evaluation

Walking the Walk: Co-producing approaches to diversifying participation in Earth and environmental science education and careers

For many people working in the environmental sciences today, the first spark of interest in the field came from experiences in nature. Whether walking, hiking or visiting the coast, immersion in the natural world can often plant the seeds of curiosity that lead to a lifelong desire to know more about how and why it works. In the UK, much of the natural “the countryside” is perceived as an overwhelmingly “white” space, hostile to people from non-white backgrounds. Not only does this mean that for many that seed is never planted, but the lack of familiarity with experiences in “the outdoors” means the fieldwork seen as necessary for an environmental education (and commonly required for accredited degree programs) presents a barrier to degree level study. This is a major problem for the field, as environmental impacts such as those driven by climate change affect everyone. Financial, cultural and opportunity barrier to accessing the outdoors, are recognised by both environmental organisations and grassroots groups. This project will bring together environmental scientists and grassroot community groups to tackle barriers in order to make outdoor learning accessible to all. We will test approaches to bring environmental science learning directly to those trying to make the UK countryside a more inclusive environment and learn from the experiences of both environmental scientists and activist groups in spending time immersed in nature.
