This State of Land Information (SOLI) report from the Land Portal assesses the state of land data in Zambia against principles of land data openness, land information availability and accessibility, and overall good land governance. The report is one of a series produced by the Land Portal, featuring in-depth analysis of country level land information and making recommendations for targeted interventions to improve compliance with international open data standards. The report identifies the various public sector sources of land data and information in Zambia, including the Ministry of Land and Natural Resources, the Ministry for Infrastructure, Housing and Urban Development, the ZAMSTATS website of the Zambian Statistical Agency, and the Zambian Geographical Portal, and examines the availability of land data and information they provide according to six key land data categories. Zambia’s legal framework for data governance and for opening up information is reviewed, and Zambia’s international and national commitments to access to information and its instruments for data and information governance are examined to assess for transparency about the purpose for collecting, storing and disseminating information. The report concludes with an evaluation of the openness of land data and information in Zambia by assessing it against 10 international best practice criteria. The report concludes that, overall, the state of land information in Zambia is partially open.
