The means: Concepts
Adaptation: Adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities
Mitigation: An anthropogenic intervention to reduce the sources or enhance the sinks of greenhouse gases
Sustainable Land Management (SLM): “The use of land resources, including soils, water, animals and plants, for the production of goods to meet changing human needs, while simultaneously ensuring the long-term productive potential of these resources and the maintenance of their environmental functions” (UN Earth Summit, 1992)
“Knowledge-based procedure that helps integrate land, water, biodiversity and environmental management (including input and output externalities) to meet rising food and fiber demands while sustaining ecosystem services and livelihoods” (World Bank, 2005).
The ecosystem approach (EbA): Strategy for the integrated management of land, water, and living resources that promote conservation and sustainable use in an equitable wayEcosystem' means a dynamic complex of plant, animal and micro-organism communities and their non-living environment interacting as a functional unit

Many of the SLM technical solutions include directly or indirectly the improvement of soil quality though increase of SOC.
In order to design, prioritize and implement the mix of interventions that can optimally achieve simultaneous multiple benefits. “Win-win” solutions that address synergistically DLDD (to achieve LDN), climate change adaptation and mitigation, and provide other co-benefits, will require understanding the degradation processes that are ongoing, as well as the socio-economic context and dynamics of the drivers of this process.
It will not be possible to export SLM approaches from one site to another without matching well the technical and site specific environmental, social and institutional aspects.

Potential areas for synergy on:
Training and education• On the ground actions that through SLM actions advance the goals od the 3 Conventions
Awareness raising• Dissemination joint products
Information generation and sharing• Common open Access platforms for data, information and knowledge sharing
Scientific research• Promotion of multidisciplinary research, more efficient use of resources
Reporting and monitoring (domestic)• One data platform at country level on environmental information, less burden and more consistency
