Community sociologist Doctor Jeni Cross has dedicated 20 years to researching the relationship between human behaviour and the systems that surround us. She tells CityChangers.org what...

Digitisation of the construction sector is an important step. It will simplify and streamline material reuse and carbon emission reduction.
