Problemscapes and hybrid water security systems in Central Ethiopia por Polaine, X. K., Nicol, Alan, Amezaga, J., Berihun, Mulatu L., Dessalegn, Mengistu, Haile, Alemseged Tamiru

“…This framing often inherits a pre-defined spatial and institutional boundary of analysis, one that largely fails to account for various externalities influencing water security beyond the hydrological unit. Moving away from this established basin-scale analysis, we present the concept of problemscapes, a systems approach for understanding how multiple physical and social drivers surrounding (and as part of) contextual water systems determine how they work and, ultimately, the outcomes in terms of the water security they provide. …”
