multisector

Multisector refers to approaches, policies, or analyses that involve several economic or organizational sectors rather than focusing on a single domain. In development policy, a multisector approach integrates health, education, agriculture, infrastructure, and other areas to address interlinked determinants of outcomes. In economics, multisector models divide the economy into sectors such as agriculture, industry, services, energy, and construction to study inter-sector linkages, output, employment, and technology spillovers.

In practice, multisector work often involves coordinated planning and budgeting. For example, a multisector budget aligns funding across ministries or agencies, while multisector analyses use input-output tables to quantify how spending or shocks in one sector affect others.

Multisector strategies also appear in corporate and organizational contexts, where diversification across different sectors can reduce risk and broaden opportunities for growth. This is common in regional development initiatives, public-private partnerships, and cross-government collaborations aimed at achieving shared objectives.

Advantages of multisector approaches include the ability to capture indirect effects and co-benefits, improve policy coherence, and enhance resilience through diversification. Challenges can include data requirements, methodological complexity, and governance coordination across multiple agencies or actors.

Applications span development planning, macroeconomic modeling, environmental and climate policy, public health, and urban or regional development. The term is used to describe initiatives, programs, or organizations that deliberately integrate multiple sectors to address complex, cross-cutting issues.
