<p>Like many cities across India, Chennai (capital of Tamil Nadu) has two tiers of slums — those with official government recognition and those without. Slums with official government recognition are then further categorised to either be objectionable or unobjectionable. Recognised slums receive government funding to provide new tenements and basic services on site. But recent studies have shown that 4.8 sq km of the Chennai metropolitan area are comprised of either unrecognised or objectionable slums. The current government strategy is to forcibly relocate families from unrecognised or objectionable slums to large-scale, high-rise settlement colonies on the distant outskirts of Chennai. Numerous civil society organisations, however, have documented that eviction and relocation results in extreme trauma for these families. The Transparent Chennai Project at the Institute for Financial Management and Research in Chennai argues that: “A far more reasonable strategy would be to once again implement the Tamil Nadu Slum Clearance Act in the spirit that it was written, and start to recognise slums and improve them in situ” (Raman and Narayan).  This thesis proposes that architectural design can improve conditions for Chennai’s urban poor without resorting to forced relocation. It argues that a new framework for slum housing can be designed that is capable of: protecting slum dwellers from environmental disasters such as rising sea levels, storm surge, and tsunamis; mitigating environmental pollution to improve hygiene; and providing economic sources of fresh water and energy through sustainable means. It further argues that this framework can be achieved in a culturally sensitive manner by acknowledging traditional and historically significant regional architectural typologies.</p>

Imminent Threat

<p>New Zealand’s coastline is rapidly receding. The increased threat of rising sea levels continues to erode the shore line causing extensive and irreparable damage to thousands of coastal properties, often dismantling communities and the kiwi dream of living near the ocean. With global temperatures continuing to rise, all of our coastal communities are at risk. The current measure of response to this issue is through managed retreat, the removal and relocation of all ‘at risk’ buildings in coastal hazard zones. While this approach is successful in preserving the physical structures, it remains an undesirable solution that forces homeowners to abandon their community and the coastline for the safety of higher ground. The retreat is hampered among debate within the effected regions as the forced detachment of long standing communities often results in the loss of ‘sense of place’ that living within a coastal community enables.  This thesis proposes that Haumoana in Hawkes Bay offers the fitting location to introduce an alternative coastal community model that actively responds to the impending hazards whilst retaining the societal poetics. Situated just south of the nearby communities of Te Awanga and Haumoana, two of the most at-risk coastal regions in New Zealand that are currently facing the prospect of dismantlement. The site was specifically chosen due to the fact that erosion is predicted to diminish half its usable land over the next century, this thesis will investigate the potential risks to the respective coastline, the role that this would play in an adaptive community, and the possible design options that can respond and enhance a future sustainable landscape.  This thesis argues that a coastal community can be designed to actively adapt and respond to the threat of erosion rather than being dismantled through retreat; that by adopting design principles that protect the land on which they are placed, the coastal hazards of the region can be lessened; and that an adaptive community model can be achieved whilst retaining the ‘sense of place’ that coastal community’s exhibit.  The thesis proposes that this can be achieved by incorporating and reinforcing natural features of the coast into the architectural design at various scales; accommodating for, and adapting to the imminent threat of erosion; and by invoking principles of sustainable design in company with adaptive planning and resilient design, thereby pushing the standards of coastal planning beyond typical practice.</p>

Buckingham Canal bank was an important water - way of old Madras. It has been facing slow death due to many reasons such as encroachments by various constructions like MRTS (The Mass Rapid Transit System is popularly called MRTS), and also the Urban poor, the slum dwellers. The slum dwellers face various problems like, flooding, insanitary conditions, health and socio-economic issues. One of the major issue is the eviction process. In this link, the Elango Street of Govindaswamy Nagar has been allotted by the Tamil Nadu Slum Clearance Board based on G.O.Ms.No 163 Housing (F) Department, Dated 28.02.1973. Elango Street escapes all the natural problems the other slums are facing, but it is expected to be evicted. This critical issue made the researcher to compare Elango Street of Govindaswamy Nagar with the other slums on the banks of Central Buckingham Canal.

The mainland coast of China is about 18,000 km long and houses about 70% of China’s largest cities and 50% of its population. For the last few decades, the rapid growth of the Chinese economy has resulted in extensive development of the coastal infrastructure and property, large-scale expansion of coastal ports, excessive reclamation of coastal land, and a significant increase in the coastal population. Previous studies have indicated that tropical cyclones (TCs) have struck the coast of China at a higher frequency and intensity, and TC-induced coastal hazards have resulted in heavy human losses and huge losses to the Chinese coastal economy. In analyzing the long-term and most recent coastal hazard data collected on the coast of China, this study has found that TC-induced storm surges are responsible for 88% of the direct coastal economic losses, while TC-induced large coastal waves have caused heavy loss of human lives, and that the hazard-caused losses are shown to increase spatially from the north to south, peak in the southern coastal sector, and well correlate to storm wave energy flux. The frequency and intensity of coastal hazards on the coast of China are expected to increase in response to future changing TC conditions and rising sea levels. A simple two-parameter conceptual model is also presented for the assessment of coastal inundation and erosion hazards on the coast of China.

Abstract The Aldabra giant tortoise ( Aldabrachelys gigantea ) is one of only two remaining giant tortoise species worldwide. Captive-bred A. gigantea are being used in rewilding projects in the Western Indian Ocean to functionally replace the extinct endemic giant tortoise species and restore degraded island ecosystems. Furthermore, large-scale translocations may become necessary as rising sea levels threaten the only wild population on the low-lying Aldabra Atoll. Critical management decisions would be greatly facilitated by insights on the genetic structure of breeding populations. We used a double-digest restriction-associated DNA sequencing (ddRAD-seq) approach to identify single nucleotide polymorphisms (SNP) among the wild population and two additional captive populations of A. gigantea . A total of 149 unlinked, putatively neutral genome-wide SNPs were identified. The values of expected heterozygosity ranged from 0.32 to 0.5, whereas the minor allele frequency ranged from 0.20 to 0.5. These novel SNP markers will serve as useful tools for informing the conservation of A. gigantea .

In the previous chapter 3 the focus of the presentation has been on the implications of climate change, as felt globally, for the environment and human societies in developing as well as in developed countries. As noticed there, the Stern Review’s conclusion that “climate change will have increasingly severe impacts on people around the world, with a growing risk of abrupt and large-scale changes at higher temperatures” (Stern Review, 2006) is shared by most scientists and governments. The Review warns that “a warmer world with a more intense water cycle and rising sea levels will influence many key determinants of wealth and well-being, including water supply, food production, human health, availability of land, and the environment” (Stern Review, p. 84).

Economic Assets

Over the next 100 years, nothing will radically change thecoastal built environment more than climate change and sea level rise. The coastal zone is home to some of our country’s most valuable ecological and socio-economic assets. Many of these locations are being demonstrably transformed dueto large-scale human and biophysical processes. The result is a potential loss of myriad ecosystem services such as storm protection, wildlife habitat, recreation and aesthetics, among others. Policy and design solutions are not truly consideringthe necessary transformation that will be required to live and work within a saturated coastal environment. The old paradigm of flood management and control will need tochange from prevention to acceptance and population will decline as businesses and individuals decide the costs are too high. The need for developing a long-term urban design and planning framework that adapts to these effects is critical. More specifically, there is a need for a “systems” approach that utilizes urban design and takes into consideration infrastructure impacts, future investments, and insurability of risk as long-term objectives to address potential impacts from both coastal flooding and rising sea levels, while at the same time guiding communities’ future land use and investment plans.

Ocean Properties

Sustained observations of ocean properties reveal a global warming trend and rising sea levels. These changes have been documented by traditional ship-based measurements of ocean properties, whereas more recent Argo profiling floats and satellite records permit estimates of ocean changes on a near real-time basis. Through these and newer methods of observing the oceans, scientists are moving from quantifying the ‘state of the ocean’ to monitoring its variability, and distinguishing the physical processes bringing signals of change. In this paper, I give a brief overview of the UK contributions to the physical oceanographic observations, and the role they have played in the wider global observing systems. While temperature and salinity are the primary measurements of physical oceanography, new transbasin mooring arrays also resolve changes in ocean circulation on daily timescales. Emerging technologies permit routine observations at higher-than-ever spatial resolutions. Following this, I then give a personal perspective on the future of sustained observations. New measurement techniques promise exciting discoveries concerning the role of smaller scales and boundary processes in setting the large-scale ocean circulation and the ocean's role in climate. The challenges now facing the scientific community include sustaining critical observations in the case of funding system changes or shifts in government priorities. These long records will enable a determination of the role and response of the ocean to climate change.

Abstract Climate change and rising sea levels, which threaten many Asian and other coastal cities, have returned the question of adaptation to unstable marine surfaces to the global discussions about urbanization, as was illustrated by a recent United Nations (UN) roundtable. As de facto counterproposals to hydroelectric dams and similar regional development projects, floating or elevated structures reject land reclamation and terrestrialization processes. Consequently, the rapidly growing number of offshore structures, which often constitute unconventional settlements, have contributed to an amphibious transformation of Earth's surface in the course of the twentieth and early twenty-first centuries. This amphibious transformation meant that both terrestrial and aquatic places have turned into human habitats. This article asks how and why today's leading environmental-political strand in large-scale marine urbanization emerged from the waters of Tokyo Bay. It investigates Japanese star architect Tange Kenzō's ‘Plan for Tokyo 1960’ (1961) and world-renowned American designer R. Buckminster Fuller's floating design called ‘Tetrahedronal City’ (1966). Emphasizing the important role that Asian cities have played in shaping global urbanization ideas and practices, Tokyo Bay became a node in the global cybernetics revolution that moved urban design into the information age. Tange's and Fuller's evolution-inspired cybernetic designs used the post-war communication technology revolution to replicate, through artificial communication networks, the biological communication systems that enable organisms to interact with their environments. Applying communication technology to recreate, in floating or elevated structures, the biological processes of growth, adaptation, mobility, and autonomy became the central environmental-political strand for large-scale marine urbanization and reducing its ecological footprint.
