OutlineContext• Complexity in tenure relationships and changes
in these relationships a challenge.• Need to collect local level records before
change occurs – accept that they’ll be “disorganised”
• Examine these records e.g. stories, videos, from the bottom up – data analysis philosophy parallels with grounded theory or factor analysis
Structure• Talking Titles approach and data model• Exploratory experiment using changing customary
system in a peri-urban area and simulated data.• Visuals and critique of some of the graphs
produced by network analysis

Problems!
• Go out and collect and relate everything and anything – create a mess
• Did this through simulation of keywords and relationships and what does the mess look like?
• Look at the mess and then focus on particular entities (e.g. persons) or relationship types – e.g. who is selling land.

Conclusions
• Tool for visualising and exploring data• May be useful in identifying strategies that people use to
defend their tenure and the complex relationships involved in this.
• Useful in monitoring change and forecasting problems as relationships change
• Useful in identifying mistakes in land records• Useful for small data sets – i.e. local level• Getting the data – useful in future, how do we persuade
people to collect data now?• Need institutions prepared to work at micro-level
