Tanzania Land Modeling Background Note supports the Tanzania Country Climate and Development Report by documenting the analysis framework for comparing business-as-usual (BAU) and aspirational (ASP) economy scenarios. It outlines how land scenarios are created, including assumptions from nationally determined contributions and sectoral strategies, and how irrigation land is allocated. It details landscape assessment models for cropland, forestry, grazing, costs, carbon, and biodiversity, then describes developing an optimization frontier and presenting scenario comparison results.

FAQs

What is the purpose of this land modeling background note?

It provides the methodological background for the Tanzania Country Climate and Development Report by explaining how land scenarios are built and evaluated to support BAU versus ASP comparisons.

How are BAU and ASP land scenarios constructed?

The note describes scenario creation using nationally determined contributions, existing government sectoral strategies, areas for policy improvement, future maps for BAU/ASP with climate action, and allocation of irrigation land.

Which topics are covered by the landscape assessment models?

It includes models for cropland, forestry, and grazing production values, cost assessment, carbon, and biodiversity metrics such as species richness and other indicators.
