We present a family of simple globally aggregated and regionalized actor-based systemdynamics Integrated Assessment models (IAMs). We first develop a global IAM in which both fossil-fuel-based capital and renewable-energy-based capital determine the production function. A business-as-usual scenario (no mitigation policy) is compared with various mitigation scenarios based on different global ca...

Cities are facing many challenges; challenges linked to world-wide trends like urbanisation, climate changes and globalisation. In parallel to these trends, we have seen a rapid digitalisation in and of different parts of society. Cities and local governments have been appointed an important role in overcoming these world-wide challenges, and subsequently, in policy practices digitalisation is ...

Intergovernmental Panel on Climate Change (IPCC) member governments approve each report's summary for policymakers (SPM) by consensus, discussing and agreeing on each sentence in a plenary session with scientist authors. A defining feature of IPCC assessment, the governmental approval process builds joint ownership of current knowledge by scientists and governments. The resulting SPM revisions ...

Effective action on climate change health impacts and vulnerability will require systems approaches and integrated policy and planning responses from a range of government agencies. Similar responses are needed to address other complex problems, such as the obesity epidemic. Local government, with its focus on the governance of place, will have a key role in responding to these convergent agend...

The move is aimed at helping local governments prepare for global warming. The federal advisory committee had been slated to provide guidance based on scientific findings of the latest National Cl...

In response to agriculture's vulnerability and contribution to climate change, many governments are developing initiatives that promote the adoption of mitigation and adaptation practices among farmers. Since most climate policies affecting agriculture rely on voluntary efforts by individual farmers, success requires a sound understanding of the factors that motivate farmers to change practices...
