Similarly, National Development Plans (NDPs), National Sustainable Development Plans, and green growth strategies of some countries include consideration for biodiversity, though the extent varies greatly. Continuing challenges in the design and implementation of biodiversity mainstreaming measures include effective horizontal and vertical institutional co-ordination, adequate human resources and capacity, particularly within sector line ministries, collection and dissemination of policy-relevant data for mainstreaming, and tracking and mobilising financial resources for biodiversity in the context of national budgets and beyond. This is due in part to National Ecosystem Assessments (NEAs) or similar studies being undertaken in some countries, including economic valuation studies.
