Storage Structures

<p>The decline of urban water bodies in India needs to be arrested for sustainable water management in rapidly expanding Indian cities. Reuse of water after partial recycling can reduce environmental stress. Delhi, the Indian capital, has a number of surviving water storage structures built by successive rulers over centuries to tackle water shortage in the summer. In modern Delhi, a fourteen million plus city, water is supplied through technological networks, hastening the decline of the old water storage structures. The old lakes are choked with filth and the step-wells are heaps of rubble. The Indian National Trust for Art and Cultural Heritage (INTACH) and the Delhi Development Authority (DDA) have undertaken a project to revive a 700 year-old water body, lying dry for decades, the Hauz Khas Lake, with treated sewage water. The idea was to raise the groundwater table and restore the natural environment of the lake, a past habitat for water birds. This paper attempts to evaluate the immediate impact and the long-term sustainability of the effort through discussions with technical personnel, field observations and interviews with local residents. Manuals and progress reports of the concerned organizations are used as secondary sources. The paper also examines the views of government officials and NGOs regarding the role of other similar projects in alleviating Delhi’s water shortage.</p>

Purpose Border environments differ as foci for conflict discourse. While classic realist theories are used to account for mechanisms of securitized borders, socially oriented theories are often invoked to characterize relaxed borders. This distinguishing pattern regarding securitization reflects a deeply rooted focus on idealized borders, based on implicit expectations that relaxed borders are a viable option and goal for all. This orientation is prone to mistaken assumptions regarding local, national and regional interests and ultimately threatens delicately balanced states of stability. This paper aims to question this somewhat simplified categorization and posit that securitized borders are longstanding realities which warrant more complex theoretical conceptualization. Design/methodology/approach The analysis is based on documentary study and qualitative field research, mapping and evaluating Israel–Jordan cross-border interactions conducted during 2006-2014. Local civilian interactions were studied using three tools: interviews, non-participant observations and a sector-based analysis of original and secondary sources. In the course of research, many tours and observations of the border region were conducted, and key actors in Israel and Jordan were interviewed: entrepreneurs, local residents, local and national government officials, security personnel and representatives of non-governmental organizations involved in the administration and funding of normalization-promoting initiatives. Findings In light of internal and external security threats which challenge states and border regions in conflict environments and in normalized settings, there is increasing value in recognizing multi-level power relations (“bringing the state back in”) that design, inhibit and ultimately control the inevitability, circumstance and social–political effectivity of any cross-border interaction. Cross-border cooperation (CBC), which evolves gradually, monitored by the border regime and reflecting actual levels of inter-state political dialogue, is a slower yet safer option and a more realistic expectation for CBC, especially in regions of minimal communication between cross-border neighbors. In the backdrop of the Middle East turmoil, Israel and Jordan mark 20 years of peaceful relations, enjoying stability based on shared political and security interests, yet displaying no apparent tendency toward increased cross-border interaction. Given the stark differences in regimes and ongoing regional unrest, this securitized border fulfills local and regional needs and is far from a temporary “second-best” reality. Originality/value The analysis is based on original fieldwork and documentary study, mapping and evaluating Israel–Jordan cross-border interactions conducted during 2006-2014.

The Sustainable Development

Due to the rapid development of economy, China has been facing severe water shortage and water pollution problems. This paper discusses three strategies developed for the urban water resource management in China, which is essential for the sustainable development of its economy. These strategies include setting high priority for demand control and water conservation, controlling pollution from the sources and increasing investment for wastewater treatment; and developing untraditional water resources, such as rainwater harvesting, wastewater reclamation, seawater utilization, etc. It is hoped that these strategies may not only solve the water shortage and water pollution problems at low capital and operational costs, but also meet the present and future needs on water resources in China.

Model Framework

Predicting and allocating water resources have become important tasks in water resource management. System dynamics and optimal planning models are widely applied to solve individual problems, but are seldom combined in studies. In this work, we developed a framework involving a system dynamics-multiple objective optimization (SD-MOO) model, which integrated the functions of simulation, policy control, and water allocation, and applied it to a case study of water management in Jiaxing, China to demonstrate the modeling. The predicted results of the case study showed that water shortage would not occur at a high-inflow level during 2018–2035 but would appear at mid- and low-inflow levels in 2025 and 2022, respectively. After we made dynamic adjustments to water use efficiency, economic growth, population growth, and water resource utilization, the predicted water shortage rates decreased by approximately 69–70% at the mid- and low-inflow levels in 2025 and 2035 compared to the scenarios without any adjustment strategies. Water allocation schemes obtained from the “prediction + dynamic regulation + optimization” framework were competitive in terms of social, economic and environmental benefits and flexibly satisfied the water demands. The case study demonstrated that the SD-MOO model framework could be an effective tool in achieving sustainable water resource management.

&lt;p&gt;The amount and dynamics of urban water storage play an important role in mitigating urban flooding and heat. Assessment of the capacity of cities to store water remains challenging due to the extreme heterogeneity of the urban surface. Evapotranspiration (ET) recession after rainfall events during the period without precipitation, over which the amount of stored water gradually decreases, can provide insight on the water storage capacity of urban surfaces. Assuming ET is the only outgoing flux, the water storage capacity can be estimated based on the timescale and intercept of its recession. In this paper, we test the proposed approach to estimate the water storage capacity at neighborhood scale with latent heat flux data collected by eddy covariance flux towers in eleven contrasting urban sites with different local climate zones, vegetation cover and characteristics and background climates (Amsterdam, Arnhem, Basel, Berlin, Helsinki, &amp;#321;&amp;#243;d&amp;#378;, Melbourne, Mexico City, Seoul, Singapore, Vancouver). Water storage capacities ranging between 1 and 12 mm were found. These values correspond to e-folding timescales lasting from 2 to 10 days, which translate to half-lives of 1.5 to 7 days. We find ET at the start of a drydown to be positively related to vegetation fraction, and long timescales and large storage capacities to be associated with higher vegetation fractions. According to our results, urban water storage capacity is at least one order of magnitude smaller than the known water storage capacity in natural forests and grassland.&lt;/p&gt;

The U.S

Starting in 1964, the U.S. federal government under President Lyndon Johnson passed an ambitious reform program that included social security, urban renewal, anti-poverty initiatives, and civil rights legislation. In cities like Los Angeles, these reforms fueled urban revitalization efforts in communities affected by economic decline. These reforms closed the gap between local residents and government officials in California and even subsequently brought the city’s African American and Mexican American population into greater political proximity. Looking closely at the impact of the Chicano Movement on the Model Cities Program, a federal initiative designed specifically for urban development and renewal, this article brings the role of U.S. government policy in shaping social justice priorities in Los Angeles, and the U.S. Southwest more broadly, into sharper view.

Whilst the issue of migration has received widespread and international debates on the geometric number of people displaced daily from one region to another, the environmental unfriendliness, socio-economic and political situations have been accused for the progressive migrant trend in most parts of the world. Bearing in mind these unprecedented situations, the tendency had always been the decision to migrate or stay to cope with adverse situation. It is against these mix feelings that the study investigates the perception of non-migrant communities to geo-hazard threats along the Mount Cameroon Volcanic Line (CVL). The study made use of both primary and secondary sources of data. Interviews were conducted with some traditional authorities, officials of the Limbe Botanic Garden, government officials and municipal authorities on the environmental impacts associated with the decision of the non-migrants in vulnerable zones. From the interview conducted a representative survey of households was then undertaken to gather the opinion of non-migrant households within the geo-hazard environment. This was aided by the use of some 120 questionnaires distributed to on-spot households exposed to geo-hazards within the Mount Cameroon mobile region. 120 questionnaires were administered and distributed to 5 sampled communities using random a sampling technique. The Mount Cameroon Volcanic Region alongside the location of communities were mapped out using ArcGIS. The Pearson Product Moment Correlation results revealed that communities have strong perception of geo-hazards despite the threats. About 80% of the communities perceived the occurrence of such hazards as mixed blessings especially the associated benefits from fertile volcanic and alluvial soils as well as floodwaters in depressions used for agricultural activities. The study further states that the myths of households to geohazard occurrence kills the science and technology as well as the resilient strategies to such geo-hazards. While the socio-cultural mechanism remains a winding driver of on-spot location in hazard-prone zones, the future of community safety should not undermine human knack responses to geo-hazards. The study recommends proper planning and adaptive measures along this volcanic line such that the traditional and cultural myths of the communities should be integrated with the modern and technological structures to resist or minimize the effects of nature on the non-migrant communities within the flanks of the Cameroon Volcanic Line.
