A Sustainable Development Initiate (SDI) is broadly defined as an over–arching socio-economic development and environmental rehabilitation initiative that is enabled and supported by large-scale property development.
An SDI refers to an integrated large-scale socio-economic development and environmental rehabilitation initiative that occurs as a result of property development, primarily funded by the private sector. In terms of the SDI principles, the planning, design and implementation of such property development should always be undertaken in a spirit of transparent partnership with the local communities and others that can help to promote suitable development in a manner consistent with government policy and the ethos of the new South Africa as is contemplated in the Constitution.

The SDI model consists of the following key objectives of sustainable development:

Building upon and promoting the comparative economic advantages of the region.
Unlocking land value.
Utilising natural resources.
Merging ecological and economic considerations in any decision making.
To promote sustainable development by building on the comparative economic advantages.
To make meaningful contribution to the eradication of poverty and inequality.
Ensuring acceptable return on capital invested by the core project investors.

Organisational Structure for the SDI In order to facilitate the establishment, implementation and management of the SDI, an organisational structure compromising a hierarchy of Public Benefit Organisations (PBO's) is to be established. A treasury Trust is to be established as the overarching entity for such organisational structure.
Implementation Programs The planning process of the SDI model will be undertaken in four phases with a number of defined phases.

The above mention phases consist of:

Inception Phase
Application Phase
Approval Phase
Implementation Phase
