Key Points• There will be trade-offs between SDG 15 and other SDGs resulting from competition for land, but there are also synergies and opportunities.• The principal opportunity of SDG 15 is that it will be recognised and integrated, along with the other SDGs, in all developments.• The main risk is that short-term priorities and a 'business as usual' approach will undermine this opportunity for integration and synergy and SDG 15 will often be overlooked.• The scale, and complexity, of challenges for conserving life on land, versus the limited resources available, pose many challenges.• Greater cross-sectoral integration, not just sectoral policy reform, is essential to advancing SDG 15.
