The Role of LandPKS in Land Use Planning

In Tanzania, the Land Potential Knowledge System (LandPKS; has been working with the National Land Use Planning Commission as well as USAID's Land Tenure Assistance (LTA) Project to assist in effective land use planning and land tenure efforts.  LandPKS is a mobile app that helps users identify their soil, and the potential productivity and long term agricultural sustainability of that soil.  By identifying areas with sustainable agricultural potential, land use planners can integrate biophysical assessments into their participatory land use planning process.  The LTA project is helping to revise village-level land use plans.  Once land use planning is complete, LTA is using a mobile technology called MAST (Mobile Application to Secure Tenure) to assist village members attain a CCRO (Certificate of Customary Right of Occupancy) for their farms and properties.  By integrating LandPKS soil information into their land-use plans, LTA and other land use planners can make better decisions about which areas within a village are suitable for agriculture, and which are not.  Focusing agricultural growth on soils suitable for sustainable agriculture not only increases farmer revenues and productivity, but saves other village land for other, less intensive uses such as grazing areas or forest reserves. 

At the national-level, Dr. Stephen Nindi, Director General of the National Land Use Planning Commission, is working with the LandPKS team to implement LandPKS tools in the future for the national land use planning process. Tanzania currently uses a 6-step process for participatory land use management, involving community members and stakeholders at every step. On the biophysical side of land use planning process, Tanzania draws from the seven land capabilities classes. Categorizing the land into these seven classes helps planners to determine which livelihood activities are sustainable in which areas. For example, land capability class one refers to land that is suitable for all land uses with normal land management practices, such as flat, well drained and fertile land. LandPKS could play a key role in helping land use planners classify land into these seven classes based on soil texture, soil water holding capacity, potential erosion risk, and potential productivity.  While soil texture is not the only important soil characteristic, it can be a critical predictor of a lands potential and its degradation risk. Implementing LandPKS in the land use planning process will simply, and cheaply, help the National Land Use Planning Commission include more biophysical data into their land use planning process.

Therefore, LandPKS has a role not only in improving sustainable land management for farmers and pastoralists, but also on a larger scale through the land use planning process.  Matching appropriate land uses to their proper soil types can increase productivity and decrease land degradation, important goals for long-term environmental sustainability.  For more information, please write to

This satellite image shows three LandPKS plots that were dug within 100 meters of each other in the agricultural village of Nyamihuu, Tanzania. The figure shows how the water folding capacities of the soils in these three sites varies drastically. This type of knowledge is important to land use planners when classifying land that is best suited for agriculture.

A Creative Collaboration for Developing LandPKS Trainings

Last week, Amy Quandt (LandPKS Global Coordinator) and Michaela Buenemann (Associate Professor of Geography, New Mexico State University) traveled to Nairobi, Kenya to help develop a comprehensive one-day LandPKS training.  Amy and Michaela worked in partnership with the Regional Centre for Mapping of Resources for Development (RCMRD), a LandPKS collaborator.  RCMRD is located in Nairobi, Kenya and works as a leading regional center for GIS and remote sensing technologies and trainings.  Lillian Ndungu at RCMRD has been a part of the LandPKS team and a major proponent of LandPKS in Kenya.  Antony Ndubi from RCMRD also joined the training development team.  
Amy (LandPKS Global Coordinator), Antony (RCMRD), Michaela (New Mexico State University), and Lillian (RCMRD) work on developing materials for a 1-day LandPKS training.
