Under the UK PACT funded project ‘Promoting nature-based solutions for land restoration while strengthening the national monitoring technical working group in Kenya’, CIFOR-ICRAF have undertaken practical training sessions with various stakeholders on using the Regreening App, a citizen science data collection initiative that enables farmers, government agents, project officers and implementors to track and provide evidence of restoration practices on the ground by reporting data on key indicators of land restoration.

This knowledge brief seeks to outline uptake of the Regreening Mobile App following two three-day practical workshops attended by a range of multi-disciplinary participants.

Healthy soil is critical for ecosystem restoration, climate change mitigation and adaptation, biodiversity conservation, water cycling, farmer livelihoods, and food and nutrition security. Despite its importance, soil health has often been overlooked, but momentum is growing as evidenced by recent high-level initiatives such as the Nairobi Declaration as part of the Africa Fertiliser and Soil Health Action Plan and the European Union Soil Mission: A Soil Deal for Europe. The UN Decade on Ecosystem Restoration was launched on 5 June 2021 to galvanise local, national and global action to restore degraded ecosystems. In the same year, the UN Food Systems Summit (UNFSS) initiated a call for coalitions of action to champion integrated, systemic approaches to transform food systems. The Coalition of Action 4 Soil Health (CA4SH) was launched to bring soil health into focus with participation across sectors and scales to ultimately raise awareness about this critical ecosystem that we depend on, but which is being degraded at unprecedented rates. Since 2021, CA4SH has grown to include nearly 200 members (as of January 2025) representing the public and private sectors, research institutions, non-governmental organisations, farmer organisations and cooperatives, individuals, youth-led organisations, and indigenous organisations to mention some. The initiative has also had a strong focus on gender equity and social inclusion (GESI) in soil and landscape restoration. The Coalition promotes soil as a unifier across a diverse set of stakeholders, building partnerships to overcome critical economic, technical and institutional barriers to the adoption and scaling of healthy soil practices. Furthermore, CA4SH facilitates evidence-based policy and practice action for the scaling of restoration practices that improve soil health. The Private Sector Guiding Group, launched as part of the UNFSS, developed a call to action to support increased investments in healthy soil, and continues to support the actions of the Coalition. Its four working groups focus on communication, soil health monitoring and implementation, policy, and financial investment. In the first three years since its launch, the Coalition has engaged in multinational dialogues and contributed to the adoption of soil health in the outcomes from the UN Framework Convention of Climate Change (UNFCCC) 27th Conference of the Parties (COP27) through the Koronivia joint work on agriculture (now the Sharm El-Sheikh Declaration), the UNFCCC COP28 UAE Declaration on Food Systems and Agriculture, the UNCCD COP16 Riyadh Action Agenda and also launched the Soil Health Resolution. Leveraging on the enabling policy environment, the Coalition catalyses public and private sector action with outcomes for economic returns and growth, productivity and rural livelihoods, climate and nature. The positioning of the Coalition in the current global environmental transition is pivotal to drive the multifaceted benefits that soil health improvement offers to food systems transformation and global adaptation to and mitigation of climate change.

On 27 May 2025, the Vision for Adapted Crops and Soils (VACS) and CA4SH co-hosted a webinar exploring the role of multi-stakeholder action in addressing financing, implementation, and knowledge barriers to scaling soil health solutions.

Healthy soil is the very foundation of our food systems and provides several vital ecosystem services, from carbon sequestration to improving food and nutrition security, to regulating the water cycle to hosting biodiversity. However, land degradation negatively impacts over 3.2 billion people globally. This webinar highlighted the critical role of healthy soil for ecosystem restoration, climate adaptation and mitigation, biodiversity, and food and nutrition security, as well as advancements in monitoring soil health using field assessments, data analytics, Earth Observation, and citizen science.

The Coalition of Action 4 Soil Health (CA4SH) is a multi stakeholder partnership committed to scaling soil health, globally. CA4SH ’s membership base comprises stakeholders from member states, the private sector, research institutions, civil society, farmer organisations, multilateral organisations, and NGOs.

To leverage the wealth of knowledge and experiences from across our partners in addressing key challenges currently constraining farmers to implement healthy soil practices, CA4SH held a three-part virtual Webinar Series in early 2024. The 2024 Webinar Series was held over three sessions under the topics of bringing soil health into policy, science & knowledge for improving and monitoring soil health, and financing healthy soil practices. The objectives were to explore soil-related themes and share experiences with a focus on tailoring and scaling successful methodologies.

This brief summarizes the sessions, and coallates lessons learned, calls to action, and opportunities for scaling these approaches to align action on soil ahead of the 2024 Rio Conventions.

Despite the benefits, there are few policies that incentivize farmers to invest in maintaining and improving soil health. This policy brief highlights opportunities for the inclusion of soil health and soil organic carbon (SOC) into the National Determined Contributions (NDC) of Kenya.
