The current tempo of climate change strategies puts the notion of sustainability in question. In this philosophy, mitigation and adaptation strategies ought to be appropriate to the sectors and communities that are targeted. There is a growing realisation that the effectiveness of both strategies hinges on climate governance, which also informs their sustainability. The application of the climate governance concept by the technocratic divide (policymakers and climate practitioners) to communities facing climate change impacts, however, is still a poorly developed field, despite extensive treatment by academia. By drawing heavily from conceptual and analytical review of scholarship on the utility of indigenous knowledge (IK) in climate science, these authors argue that IK can be deployed in the practice of climate governance. It reveals that the merits of such a deployment lie in the understanding that the tenets of IK and climate governance overlap and are complementary. This is exhibited by examining the conceptual, empirical and sustainability strands of the climate governance-IK nexus. In the milieu of climate change problems, it is argued that the basic elements of climate governance, where actions are informed by the principles of decentralisation and autonomy; accountability and transparency; responsiveness and flexibility; and participation and inclusion, can be pragmatic particularly to communities who have been religiously observing changes in their environment. Therefore, it becomes necessary to invigorate the participation of communities, with their IK, in designing climate change interventions, which in this view can be a means to attain the objectives of climate governance.

In recent years, urban flood modelling studies have taken the form of either validation against observations of a single event or benchmarking models of varying complexity for a synthetic flood event. In this paper, the latter framework is undertaken for hypothetic flooding scenarios at Greenwich on the River Thames, UK. A simple diffusion wave storage cell model, LISFLOOD-FP, is compared to a fully 2D hydrodynamic model, SOBEK, at multiple resolutions for a 1-in-100 year return period event. The models yield consistent results at the highest resolution (5 m) with minor differences accounted for by inertial effects and model schematisation. Secondly, both models predict significant degradation in model results at coarse resolutions compared to the high resolution benchmark. Specifically, results at 25 and 50 m suggest different flow structures emerge as the representation of urban structures becomes more coarse. As a result of this finding, the models are setup using a digital terrain model (DTM) with the buildings removed to investigate these emergent flow structures.

There is now considerable interest to understand how local communities experiencing climatic risks can benefit from climate change responses. As this agenda unfolds, there is need to understand the impact of climate-related interventions from the perspective of local populations targeted by such projects. Existing assessment approaches tend to concentrate on the environmental and economic impacts of projects that minimise greenhouse gas emissions. This study assesses the social aspect of a domestic biogas project that was intended to address the twin challenges of poverty and climate change in Sogwala village, Zimbabwe. A three-tier methodological execution process was adopted, involving field reconnaissance, household survey and key informant interviews. The focus was on measuring the social dimension of the changes brought about by the project, from the experiences of participating households. With a consciousness of assessment challenges associated with community projects, social capital parameters were used to assess the project’s contribution to the social well-being of the villagers. Overall, results show that the biogas project has the potential to facilitate social development through improved trust and social networks. Despite the contested climatic benefits associated with small-scale household biogas digesters, projects of this nature can enhance community relationships and networks, upon which other development interventions can be operationalised.
