Estimating methane wetland emissions at the global scale based on remote sensing : long term and inter-annual variabilit...
Methane (CH₄) plays an important role in atmospheric chemistry and is a powerful greenhouse gas, responsible for a third of current radiative forcing. Open surface waters (lakes, rivers and reservoirs) and wetlands represent a major source of CH₄ on a global scale. However, their contribution remains uncertain in terms of total contribution (25-45%...
Modelling the effect of free convection on permafrost melting rates in frozen rock clefts
This research develops a conceptual model of a karst system subject to mountain permafrost. The transient thermal response of a frozen rock cleft after the rise in the atmospheric temperature above the melting temperature of water is investigated using numerical simulations. Free convection in liquid water (i.e. buoyancy-driven flow) is considered....
Chronicle of a disaster foretold: The politics of restoring Lake Urmia (Iran)
Like many of the world’s large-scale terminal lakes, the Urmia saltwater lake in northwestern Iran is undergoing a process of desiccation. The anticipated economic, social, environmental and health consequences of this are daunting. We set out to examine the policies that have been designed in response to the lake crisis in the past twenty years. W...
Blinded like a state: Water scarcity and the quantification dilemma in Morocco
Over the last two decades, the Moroccan state has had to deal with some deeply uncomfortable knowledge regarding mounting water scarcity. This presents governing actors with a difficult dilemma. On the one hand, this knowledge is politically disturbing as it could undermine prevailing hydro-agricultural policies, which are based on the promise of u...
