Multi Purpose Land Consolidation
• Instrument for land reform• Spatial Planning Context - Implementation• Implications for
– agricultural productivity, – environmental sustainability, and the– economic and social status of the rural
households – improvement of lively hood
• Balance between development and conservation issues

Comprehensive land Consolidation (FAO)
• The re-allocation of parcels together with a broad range of other measures to promote rural developmen
• Examples of such activities include: – village renewal, – support to community based agro-processing,– construction of rural roads, – construction and rehabilitation of irrigation and drainage
systems, – erosion control measures, – environmental protection and improvements including the
designation of nature reserves, and the – creation of social infrastructure including sports grounds and
other public facilities’
Process
• agreement on the to be area involved • preparation and voting of the land-use plan in a specific
area, • inventory of the (ownership, use) rights on the land and
the valuation of the land, • drafting and confirmation of the reallocation plan and
other functions to be realised, • implementation of the reallocation plan and creation of
other functions, • financial arrangements taking into account the benefits,
and • registration

Land Consolidation can be voluntary based
• Small projects
• Design by participants
Surveyors needed
• to make a list of right holders (formal ownership, land use, informal land use)
• to organise involvement of right holders in re-allocation
• to set up a list of financial arrangements

Information Management
• Spatial data, multiple themes
• Preferences entitled parties
• Design of Re-allocation plan
• Surveys
• Land Administration Domain Model

• http://webbtv.compodium.se/tallberg09/ondemand/034/
• The Tällberg Forum 2009 took place on 24-28 June 2009, under the theme "How on earth can we live together, within the planetary boundaries?". Over 400 leaders from business and politics, thinkers, scientists, artists and entrepreneurs gathered for four days to address global issues of urgency and common interest, through conversation, reflection and working sessions.
