LAND AND POVERTY CONFERENCE 2019: CATALYZING INNOVATION
MOTIVATION
• Indicator of SDG Target 1.4: documented or recognized evidence of tenure
• Problem: majority of people do not have formally documented land rights
• How do stakeholders assess the potential role
of Unmanned Aerial Vehicles (UAVs) to support the documentation of land rights?
CONTEXT: ITS4LAND
Program: EU granted H2020-ICT-2015
Research and Innovation Action
Start date: 2016-02-01 Duration: 48 months
Consortium: 8 partners across Europe and Africa
Objective: We’re creating seven new tools to make land rights mapping faster, cheaper,

mapping
BACKGROUND KENYA
• Characterized by arid and semi-arid landscapes
• Statutory and customary land tenure with fixed and general boundaries • Land-related conflicts due to lack of
legal certainty over land
• Poor quality of land information • Disconnected land administration

RESULTS
• Clear and easy ranking • Consensus among groups • Correlation with spatial resolution or measurement accuracy
RESULTS
• Consensus among groups
• Critical point of time
efficiency is the unknown time for UAV registration and flight authorization • Once authorized –
immediate realization of UAV flights possible
RESULTS
• One-off costs for UAV equipment and field survey
• Recurring costs for satellite images and aerial images
• Economies of scale (scale increases –
RESULTS
• Most substantial
variance of responses • High level of training for
Field survey and Aerial images
• Current UAV legislation as hindering factor
• Automation of UAV data capture as opportunity
RESULTS
• Ranking clear for indirect surveying techniques
• Large variance for field survey
• UAV images allow for community involvement during data capture on
RESULTS
• Reliability of technique versus reliability of person who collects data
• Discrepancies in field survey and satellite images
• Automated workflow for UAV image processing is reliable (esp. PPK, RTK) • Ground control points
CONCLUSION
Interactive gaming supported the identification of opportunities and challenges of UAV images as base data for land rights mapping in
Kenya.
Opportunities Challenges
• Allow for public participation • Independence of data capture • Support endeavors to digitize
the current land registration
• GNSS equipment for
RTK/PPK UAV data capture • Current regulatory vacuum • Lack of adequate capacity
