“…There is the need for a city wide screening tool that can identify sites potentially suited to stormwater water harvesting, including existing developments and new growth areas. Geographic Information System (GIS) have been recognised as a useful tool for supporting the identification of potential stormwater harvesting sites, as it has the capability for spatial analysis of multiple datasets representing bio-physical and anthropogenic factors (Malczewski, 2004;Mbilinyi et al, 2005). GIS enable the rapid screening of potentially suitable stormwater harvesting sites across a region, which is an inherently spatial problem.…”

“…In India, potential sites for water harvesting were identified applying the International Mission for Sustainability Developments guidelines within a GIS environment (Kumar et al, 2008;Singh et al, 2009). In South Africa, there are several studies where GIS based decision support systems were developed to locate suitable sites for water harvesting (De Winnaar et al, 2007;Kahinda et al, 2008;Kahinda et al, 2009;Mbilinyi et al, 2005). There are similar examples in other countries where GIS was used to consider stormwater harvesting potential in rural areas (Bakir and Xingnan, 2008;El-Awar et al, 2000;Hamdan et al, 2007;Kirzhner and Kadmon, 2011;Viavattene et al, 2008;Ziadat et al, 2012).…”

There is a need to re-configure current urban water systems to achieve the objective of sustainable water sensitive cities. Stormwater represents a valuable alternative urban water source to reduce pressure on fresh water resources, and to mitigate the environmental impact of urban stormwater runoff. The selection of suitable urban stormwater harvesting sites is generally based on the judgement of water planners, who are faced with the challenge of considering multiple technical and socio-economic factors that influence the site suitability. To address this challenge, the present study developed a robust GIS based screening methodology for identifying potentially suitable stormwater harvesting sites in urban areas as a first pass for subsequent more detailed investigation. The study initially evaluated suitability based on the match between harvestable runoff and demand through a concept of accumulated catchments. Drainage outlets of these accumulated catchments were considered as potential stormwater harvesting sites. These sites were screened and ranked under three screening parameters, namely demand, ratio of runoff to demand, and weighted demand distance. The methodology described in this paper was successfully applied to a case study in Melbourne, Australia, in collaboration with the local water utility. The methodology was effective in supporting the selection of priority sites for stormwater harvesting schemes, as it provided the basis to identify, shortlist, and rank sites for further detailed investigation. The rapid identification of suitable sites for stormwater harvesting can assist planners in prioritising schemes in areas that will have the most impact on reducing potable water demand.

“…Sustaining a water system requires personnel training, monitoring, health and safety regulations, and communication with users [25]. Sustainable water utilities should involve the population which they serve, and utilize the local knowledge of water resources and traditional management practices [89]. The inclusion of women in water management decisions is particularly important in cultural contexts where women are traditionally charged with collecting water for domestic consumption and use, as water management can have immediate and long-term impacts on gender equality [85,90].…”

Sustainable water management (SWM) requires allocating between competing water sector demands, and balancing the financial and social resources required to support necessary water systems. The objective of this review is to assess SWM in three sectors: urban, agricultural, and natural systems. This review explores the following questions: (1) How is SWM defined and evaluated? (2) What are the challenges associated with sustainable development in each sector? (3) What are the areas of greatest potential improvement in urban and agricultural water management systems? And (4) What role does country development status have in SWM practices? The methods for evaluating water management practices range from relatively simple indicator methods to integration of multiple models, depending on the complexity of the problem and resources of the investigators. The two key findings and recommendations for meeting SWM objectives are:(1) all forms of water must be considered usable, and reusable, water resources; and (2) increasing agricultural crop water production represents the largest opportunity for reducing total water consumption, and will be required to meet global food security needs. The level of regional development should not dictate sustainability objectives, however local OPEN ACCESSWater 2014, 6 3935 infrastructure conditions and financial capabilities should inform the details of water system design and evaluation.

“…Il existe des raisons irréfutables pour considérer la connaissance locale comme une ressource nationale de valeur (Warren et Rajasekaran, 1993). Par exemple, un travail récent sur la récolte des eaux de pluie a montré la versatilité de la connaissance locale en différents endroits de la Tanzanie, notamment dans les montagnes Pare (là où le secteur de Mwanga est localisé) (Mbilinyi et al, 2005).…”

Cet article présente une analyse préliminaire d’un travail mené le long des pentes des montagnes et dans les plaines du nord de la Tanzanie. Un fort degré d’interdépendance a pu être mis en évidence parmi des groupes d’individus de langues et de cultures différentes, de statuts socio-économiques variés. Leurs interactions se situent le long de gradients environnementaux allant de l’amont à l’aval. On désignera cela « adaptation socio-géographique » au changement climatique. Cependant, l’analyse et la discussion présentées ajoutent la complexité à n’importe quelle notion simpliste « d’adaptation au changement climatique » puisque les changements sont multiples et l’adaptation, de fait, reste complexe
