    Recent developments in Environmental Flow (E-flow) frameworks advocate holistic, regional scale, probabilistic E-flow assessments that consider flow and non-flow drivers of change in socio-ecological context as best practice. Regional Scale ecological risk assessments of multiple sources, stressors and diverse ecosystems that address multiple social and ecological endpoints, have been undertaken internationally at different spatial scales using the relative-risk model since the mid 1990's.

    City planners, urban innovators and researchers are increasingly working on ‘future city’ initiatives to investigate the physical, social and political aspects of harmonized urban living. Despite this, sustainability principles and the importance of urban groundwater are lacking in future city visions. Using London as a case study, the importance of groundwater for cities is highlighted and a range of future city interventions may impact on groundwater are reviewed.

    Mozambique

    Moçambique é um país em vias de entrar no complexo mundo dos países produtores de produtos energéticos. Um grande influxo de capitais tornou o país num dos destinos privilegiados do investimento estrangeiro, o que permitiu/facilitou uma gestão especulativa de receitas futuras. Receitas rápidas e avultadas de capitais e aumento das reservas de divisas permitiram políticas fiscais e monetárias expansivas, reforçando o padrão de acumulação sectorial, social e espacialmente concentrado e de realização no exterior.

    We are in the Anthropocene. For millennia, human actions have been shaping the world to the degree that they are inscribed in the geological and ecological record. Recently, this has been occurring with increasing speed and influence. This means we need to be asking integrative and effective questions about the world and how we relate to and in it. Human niche construction has broad and deep effects not just on landscapes and environments, but on the myriad of other beings sharing space with us.

    Ghana

    Increasing climate variability and challenge in access to water pose major impediments to rainfed agricultural productivity. Extensive flooding of agricultural lands during the rainy season and lack of water during the 8-month long dry season affect the livelihood of the people in the northern Ghana, a situation that calls for better water management practices. The use of aquifer storage and recharge (ASR) based technique, helps to reduce flooding and improve access to water during the dry season; however such technology has specific requirements for successful implementation.

    Although Ethiopia has abundant land for irrigation, only a fraction of its potential land is being utilized. This study evaluates suitability of lands for irrigation using groundwater in Ethiopia using GIS-based Multi-Criteria Evaluation (MCE) techniques in order to enhance the country's agricultural industry. Key factors that significantly affect irrigation suitability evaluated in this study include physical land features (land use, soil, and slope), climate (rainfall and evapotranspiration), and market access (proximity to roads and access to market).
