Rural and urban localities are under continued pressure to ensure vibrant, liveable and sustainable environments for their inhabitants. Citizen stewards are forging ahead with innovative small-scale initiatives to provide grass roots solutions for improving environmental and cultural resilience within these landscapes. Enterprises encompass everything from home gardening for providing habitat for native wildlife, to street art for improving visual urban aesthetics, to income diversification strategies for smallholder farmers. These initiatives are often undertaken with limited access to locally relevant environmental information to help guide decisions. In turn, government agencies face challenges with understanding the scale, scope and impact of such bottom-up initiatives in the absence of effective tools for collecting data. Recently, much exciting research has emerged through co-development initiatives between researchers and public contributors to improve communal accessibility to valuable and useable geographical data. Easy-to-use mobile applications have evolved which can provide environmental information to citizen participants to help them map, plan and monitor their enterprises. Such technological enterprises can also provide data to researchers and stakeholders on how the diversity of these spaces links with broader outcomes for human and ecological wellbeing. In this interdisciplinary session we invite research which showcases the value-add of public participation mobile [often geospatial in nature] applications for supporting improved biodiversity and/or cultural inclusivity. Case studies which demonstrate a transitioning towards improved functionality and viability of landscapes under the multitude of socio-ecological threats are welcomed. Likewise, we welcome research which contributes to our broader scientific understanding of sustainable practice within landscapes through using participatory mapping processes. This could also include critical perspectives on the limitations, challenges, ethical considerations and digital divides of using participatory approaches or techniques.
