A diverse, thriving local economy has been identified as an important requirement for sustainability. A diverse mix of small business means that economies are more resilient and jobs are retained even if there are economic downturns in one, or more, sectors. Local small business have to deal with the consequences of their actions in the long term and therefore tend to be more interested in sustainability and minimising negative local impacts. In rural areas diversity of work and economic opportunities help to retain youth, maintain communities and reduce disruptive rural-urban migration.
Local economies can be supported through procurement which favours local production. In South Africa the Preferential Procurement Policy Framework Act (PPPFA) Act 5 of 2000 enables the government to use procurement to support increased local production. It sets out minimum local content requirements for designated sectors for goods, works and service contracts.
In order to support the achievement of minimum local content requirements the South African Bureau of Standards (SABS) has developed SATS 1286 which are technical specifications for determining local content. The SABS also provides a verification service which confirms local content. The specifications and service were launched in July 2013.
