We live in the critical decade for climate change. The world increasingly experiences the damages and losses from extreme weather events caused by human-made climate change. Crop losses, devastating floods, catastrophic wildfires and rising sea levels cannot be ignored. If we do not achieve a balance between our greenhouse gas emissions and removals from the air, these impacts will become considerably worse and more dangerous. The UK has legally committed to achieving a net zero greenhouse gas balance by 2050. However, it is currently hotly debated how this goal can be achieved. The Land Use for Net Zero (LUNZ) Hub brings together researchers, policy-makers, industry leaders, innovators and rural community representatives from all four nations of the UK. Our 33 member organisations include researchers and practitioners from green finance, agricultural advisory organisations, NGOs, and an arts collective. The goal of the LUNZ hub is to accelerate positive land use change that reduces harmful greenhouse gas emissions, increases food security and restores a healthy environment for plants, animals and people. The Hub will equip UK policy-makers, industry and stakeholders with the advice they need, in the format and timeframe they require, to take policy decisions to help avert dangerous climate change and lead to a better future. We will bring together scientific evidence and stakeholder perspectives to define shared, net zero scenarios (plausible alternative futures)and credible pathways (steps including policies and incentives) to achieve them by 2050. The Hub will establish an Agile Policy Centre, a Net Zero Futures Platform, and a Creative Methods Lab. Within the Hub, our four National Teams will work together with our Topic Expert Groups to build capacity for a Just Transition to net zero that benefits people and planet alike. The Hub will support the UK Government and the devolved administrations in achieving multiple environmental goals by understanding the impacts of policy decisions on all relevant aspects, including renewable energy, agriculture, planning frameworks, afforestation, water management, nature conservation, biodiversity, and rural economies. The Hub will work on several priority policy areas: 1. Land use change that benefits the environment and is socially just, leading to ecosystem co-benefits such as biodiversity, soil health, human health and wellbeing, and green growth at national, regional and local levels; 2. Future agricultural, environmental and food policies that deliver a net zero future, building on the Agriculture Act 2020, Environment Act 2021, Agriculture Bill 2022 (Wales) and 2023 (Scotland), including future sources of finance, payment schemes and measures to reduce greenhouse gas emissions and increase removals while strengthening food security, biodiversity and land-based businesses (e.g. farms, crofts, forestry); 3. Integrating policy with carbon and natural capital markets, to ensure that the drivers and mechanisms for on-the-ground transformation work together for optimal outcomes. Achieving net zero by 2050 will require new technologies and practices which lower greenhouse gas emissions. These will include soil improvement practices, peatland protection and restoration, removal of greenhouse gases from the air and decarbonising our economy, large-scale tree-planting to take up carbon from the air, creation and restoration of habitats, transitioning to a circular economy, and significantly reduce food waste and consumption of higher emitting foodstuffs. To cover these diverse areas the Hub is comprised of the primary players in the UKRI AgriFood for Net Zero Network+, Landscape Decisions Programme, and principal investigators from Greenhouse Gas Removals, Changing the Environment, Digital Environment, AI for Net Zero, and Treescapes Programmes. This team have the experience and expertise to bring together a single voice of authority for Net Zero transformation in the UK.

Antimicrobial resistance (AMR) is a multifaceted, wicked problem. Evolution of resistant microbes can arise anywhere along agrifood chains, leading to diseases that cannot be treated by currently used medicines. Human, animal, plant and environmental health are interconnected; actions such as antimicrobial use (AMU) in one sector, may influence AMR arising in another. National and global movements of people, animals and goods therefore creates a web of factors that influence AMR, necessitating systems-based approaches to effectively tackle problems. AMR transcends disciplinary boundaries, requiring collaboration amongst human and veterinary healthcare professionals, researchers from multiple disciplines, policymakers, regulators and the agriculture sector. The benefit of the AMAST (AMr in Agrifood Systems Transdisciplinary) Network is that it brings together, for the first time, actors from diverse backgrounds across agrifood systems to co-develop solutions to AMR challenges through collaboration, dialogue and action. Our aims are to CREATE a transdisciplinary community that bridges the range of research expertise, working together and directly with industry and policymakers, to collectively consider complex configurations in agrifood systems. We will HARNESS the collective strength of experience and expertise of our members to fully understand the challenges and opportunities to mitigate AMR in agrifood including across production systems, such as crop, livestock and aquaculture. From this understanding, and the collaborative resolve established amongst the AMAST membership, we will PREPAREnew systems-level frameworks for transdisciplinary research and partnership that acknowledge the dynamic interactions between actors within those agrifood systems. These frameworks will be used to guide understanding on (new) interventions on AMU and other AMR-promoting practices, that will lead to reductions in AMR in targeted agrifood subsystems, whilst minimising unintended consequences in others to achieve holistically beneficial outcomes. AMAST has been initiated by researcher coalition and partners from across the United Kingdom, representing agrifood-related trade and farming associations, agrifood research and innovation institutes, business development consultants, food-sector networks, government-led AMR surveillance initiatives, and other AMR-focussed networks. The formation and progression of AMAST will be guided by an expert panel, sharing their perspectives on AMR and connections related to infectious disease, aquaculture, livestock, food systems, food safety and transdisciplinary research partnering approaches. Core activities encompassed in 11 objectives at the outset of AMAST will be driven by meaningful engagement between industry, policy and academic researchers in a series of directed-events to understand varying perspectives, expertise and accompanying evidence on current food production processes that exacerbate AMR; and the challenges of moving away from current practices to mitigate AMR without compromising yield, quality and welfare. These events will include stakeholder interviews, workshops, and horizon-scanning activities, knowledge synthesis and authentically focused knowledge-exchange outputs such as perspective ('white') papers. These activities will inform subsequent programming to be developed within AMAST, including use of AMAST Flexible Funds supporting collaborative activities such as targeted researcher and industry short-term-scientific-missions, an AMAST Fellowship training that is authentic to AMR challenges, and further knowledge synthesis activities. Visibility of AMAST outputs and capacity building within and outside the network will occur using a tailored communication strategy and creative multimedia.
