There are two reasons for this. Firstly, the major clean-tech strengths of the Negev lie only in a subset of clean-tech activities: water efficiency, including wastewater treatment, desalination and drip irrigation, and renewable energies technologies, including solar, biofuel and geothermal energy production. Secondly, within this subset of activities, the Negev contains only a subset of the actors normally found in fully-fledged clean-tech clusters. Whilst it possesses research organisations, some lead customers, and innovative start-ups, there are gaps in the region’s business development services and growth finance, high-skilled labour and supplier base.
