Evaluation of Hydraulic Performance: A Case Study of Etana Small Scale Irrigation Scheme: Wolaita Zone, Ethiopia
Abstract: The conventional furrow irrigation system is inherently inefficient in wolaita zone, while the suboptimal management and operation (inflow discharge and cutoff time) are considered as one of the main reasons for satisfactory hydraulic performance. Addressing these issues, the furrow irrigation system which is only practiced in the study area was evaluated on three fields under routine farmer management in wolaita zone. The study consisted of field experiments and simulation modeling. …

Challenges in implementing an Opportunistic Adaptation approach in Bangkok
Abstract: The 2011 floods should have been a wake-up call for Bangkok, yet the question is what the situation is now, eight years later. Did this disaster cause a change in our attitude to climate change or not? Opportunistic adaptation (OA) is a tool used in urban planning, designed to help stakeholders share a common vision of what/when/where can happen in the future, given uncertain conditions like, e.g., climate change. The …
