Abstract: Phosphorus sustains global food production and is, therefore, of crucial importance to human nutrition and health. However, its mismanagement can lead to water pollution and environmental degradation in addition to low crop yields. In many parts of sub-saharan Africa, phosphorus deficiency constrains agricultural productivity and exacerbates food insecurity. Despite these challenges, phosphorus remains a fragmented topic in global and African policy. To address these issues, the 8th Sustainable Phosphorus Summit (SPS8) was convened in Africa for the first time. SPS8 took place in Accra, Ghana, between 30th September and 3rd October 2025. The Summit was an international collaboration, with co-conveners from the Council for Scientific and Industrial Research (CSIR) – Ghana, the Forum for Agricultural Research in Africa (FARA), The UK Centre for Ecology & Hydrology West Africa Office, Lancaster University and Rothamsted Research. In this paper, we give a detailed overview of the key messages and insights that emerged from highlight talks, lectures, working groups and field trips. We also discuss and reflect on the challenges of delivering an inclusive summit, from designing solutions to benefit-sharing. SPS8 demonstrates that inclusive, cross-sector knowledge-exchange events are crucial to support and enable phosphorus sustainability on the continent of Africa and globally and to enable the next generation of interdisciplinary phosphorus researchers.

Abstract: A brain drain phenomenon, i.e. the migration of highly skilled professionals, has represented and still represents a severe loss of intellectual capital for Global South countries. Factors driving this migration include limited research infrastructure, funding constraints, political instability and the lack of scientific career prospects in the Global South and the consequences are multifaceted. While this can hinder local development in the Global South, it simultaneously enriches research ecosystems in the Global North, exacerbating existing global inequalities in science and technology. Under this scenario, scientific diasporas represent an effort to counterbalance the brain drain scenario through initiatives that aim to increase science and technology development, which are led by self-organised expat professionals and scientists. While we can find some successful examples of international cooperation driven by scientific diasporas, without a proper organisation and full participation of the governments of the countries of origin, scientific diasporas can become dysfunctional and can promote more migration upon training. We, five early-career scientists, discuss our perspectives and personal reflections on scientific diasporas. We describe three migration models of highly skilled professionals, starting with a brain drain model, scientific diaspora and dysfunctional scientific diaspora and provide some ideas to help the implementation of successful scientific diasporas. We believe that migration must be a personal decision seeking scientific growth and professional development and not the only option we should have to pursue a fulfilling career in science.

Abstract: Defined as the benefits derived from nature to humans, the Ecosystem Services (ES) concept clarifies how ecosystems contribute to human well-being. Despite its relevance, integrating this concept into decision-making processes remains a challenge. Participatory approaches have proven crucial in developing mechanisms for managing, conserving, sustainably using and valuing ES. This work aimed to analyse the perceptions of Portuguese Biosphere Reserves’ (BR) managers regarding the ES provided by these territories through a participatory workshop. During the workshop, each participant specified the most relevant ES provided by the BR. The study identified three key ES: "Cultivated terrestrial plants (including fungi, algae) grown for nutritional purposes", "Characteristics of living systems that enable scientific investigation or the creation of traditional ecological knowledge" and "Characteristics of living systems that enable education and training". Additionally, participants discussed perceived threats, opportunities and potential solutions to enhance the value of these key ES in these areas. "Climate change" and "Pollution" were identified as the most significant threats, while "Climate adaptation", "Quality of life" and "Sustainable agriculture" emerged as the main opportunities. Solutions to address threats and maximise opportunities include the establishment of a closer, systematic and articulated relationship within BR to promote sustainability and resilience. Overall, the workshop was positively evaluated and deemed productive. It was also considered a powerful tool to foster collaboration towards a more holistic promotion of BR' sustainable governance, benefitting the environment, communities and the economy.

Abstract: Municipal solid waste management (MSWM) has become one of the most pressing environmental issues in South Asian cities, the more so as it is closely linked to drinking water quality, sanitation and human health affecting mostly the urban poor, as well as to global climate change. Looking at recent governance initiatives in three South Asian cities developed in the wake of natural or human-induced crises, the project will focus on how to render MSWM improvements politically feasible and socially acceptable, which is a pre-requisites for functioning SWM systems, and thus for (environmental and social) sustainability more generally. The goal of this project, therefore, is to identify, analyze and promote the political and sociocultural processes that are necessary to enable the functioning of MSWM systems. In particular, alternative practices and systems are promoted, whereby institutional hierarchies are decentralized, favoring horizontal accountabilities and whereby waste chains are shortened and transformed into closed loops implying a more circular waste economy in which both environmental and local livelihood benefits would accrue. The project puts emphasis on mutual learning through horizontal South-South partnerships between local authorities, civil society actors and researchers across South Asia.

Abstract: Apps for mobile devices and web-based platforms are increasingly used in citizen science projects. While extensive research has been done in multiple areas of studies, from Human-Computer Interaction to public engagement in science, we are not aware of a collection of recommendations specific for citizen science that provides support and advice for planning, design and data management of mobile apps and platforms that will assist learning from best practice and successful implementations. In two workshops, citizen science practitioners with experience in mobile application and web-platform development and implementation came together to analyse, discuss and define recommendations for the initiators of technology based citizen science projects. Many of the recommendations produced during the two workshops are applicable to citizen science project that do not use mobile devices to collect data. Therefore, we propose to closely connect the results presented here with ECSA’s Ten Principles of Citizen Science.

Abstract: Marine optical imaging has become a major assessment tool in science, policy and public understanding of our seas and oceans. Methodology in this field is developing rapidly, including hardware, software and the ways of their application. The aim of the Marine Imaging Workshop (MIW) is to bring together academics, research scientists and engineers, as well as industrial partners to discuss these developments, along with applications, challenges and future directions. The first MIW was held in Southampton, UK in April 2014. The second MIW, held in Kiel, Germany, in 2017 involved more than 100 attendees, who shared the latest developments in marine imaging through a combination of traditional oral and poster presentations, interactive sessions and focused discussion sessions. This article summarises the topics addressed during the workshop, particularly the outcomes of these discussion sessions for future reference and to make the workshop results available to the open public.

Abstract: Citizen science is an approach of public participation in scientific research which has gained significant momentum in recent years. This is particularly evident in biology and environmental sciences where input from citizen scientists has greatly increased the number of publicly available observation data. However, there are still challenges in effective networking, data sharing and securing data quality. EU BON project has analyzed the citizen science landscape in Europe with regards to biodiversity research and proposes several policy recommendations. One of the recommendations is a Pan-European citizen science gateway for biodiversity data with dedicated tools for data collection and management. The prototypes of the gateway components are part of the EU BON biodiversity portal and described in current report.
