Governance of Tenure


Providing mapping support at the ground level

SOLA supports cadastre and registration functions and services provided by land offices. SOLA provides land administration agencies an enterprise level system, incorporating international best practice and standards. SOLA is designed to facilitate the essential customization required to meet specific needs of a country. 

SOLA is open source software with supporting documents available, and its customization is always the first step in implementation. The level of customization efforts varies from country to country and depends on local context (e.g. legislation and rules, previous experience with other systems, common practices and local standards). Therefore, while applying SOLA customization, if needed with the help of experts, local developers  have to be engaged and involved. In this way, FAO encourages software development skills transfer to ensure in-country expertise to maintain and extend local implementations of SOLA.

Who needs SOLA?

Although SOLA can be used to establish a land registration and cadaster system, it is seen as  beneficial more so for small countries which have little capacity and funds to develop a new system, or countries which can learn from the business processes and use SOLA applications as a prototype or starting point for further expansion and development, etc. If a country requires SOLA implementation, it can use the SOLA deployment checklist, prepared by FAO to assess country readiness and provide further recommendations.
