The 1934 floods in Tabriz, N. W. Iran

The disastrous floods of July 1934 in Tabriz are examined in the context of the history of floodinginthe city, which is crossed by a dry stream bed liable to sudden Inundation by mountain torrents from the southeast. Few details of past events have survived, suggesting that relatively little significance has been attached to them. Typically, flood dykes were inadequately maintained. This neglect, combined with a radical alteration in urban topography after 1925, when broad straight avenues were constructed through the old heart of the city, led to serious losses from flooding twice in 1929 and again in 1934. Enhanced perception of the flood risk finally found expression in the adoption of large scale engineering measures to mitigate future events, including strengthening protective dykes and widening the river channel through the city. These works have reduced vulnerability to flooding from river overflow. No long-term detrimental Impact of the 1934 flood has been observed. Some of the physical and social parameters that have influenced the vulnerability of Tabrizinthe past continue to be present both there and elsewhere in Iran, and they may be characteristic also of other regions with comparable natural environments or in a similar stage of socio-economic development.     

Presenting Triple-Wins? Assessing Projects That Deliver Adaptation,Mitigation and Development Co-benefits in Rural Sub-Saharan Africa

The concept of climate compatible development (CCD) is increasingly employed by donors and policy makers seeking ‘triple-wins’ for development, adaptation and mitigation. While CCD rhetoric is becoming more widespread, analyses drawing on empirical cases that present triple-wins are sorely lacking. We address this knowledge gap. Drawing on examples in rural sub-Saharan Africa, we provide the first glimpse into how projects that demonstrate triple-win potential are framed and presented within the scientific literature. We identify that development projects are still commonly evaluated in terms of adaptation or mitigation benefits. Few are framed according to their benefits across all three dimensions. Consequently, where triple-wins are occurring, they are likely to be under-reported. This has important implications, which underestimates the co-benefits that projects can deliver. A more robust academic evidence base for the delivery of triple-wins is necessary to encourage continued donor investment in activities offering the potential to deliver CCD.

Establishing the green neighbourhood: approaches to neighbourhood-scale sustainability certification in Portland,Oregon

ABSTRACT

While local governance is widely acknowledged as an important element in the pursuit of sustainability, local action alone is insufficient to produce lasting change. One recent solution to this quandary has been the production of certification frameworks that encourage sustainable development at the neighbourhood scale by providing local actors with standardised definitions of sustainable practices. While these frameworks facilitate the spread of sustainable development strategies between local communities, there are significant contrasts between their approaches to encouraging local sustainable development that simultaneously fulfils global objectives. This article explores these contrasts through two neighbourhood-scale sustainability certification frameworks: LEED for Neighborhood Development (LEED-ND) and the EcoDistricts Protocol. Analysis of these frameworks in the context of two centrally-located neighbourhoods in Portland, Oregon, reveals substantial contrasts between the two frameworks in terms of the relative flexibility of their sustainability metrics, the time frame over which decisions regarding sustainable development are made, and community involvement in the process of pursuing specific objectives. Furthermore, it suggests that greater flexibility in the application of standards, continuous governance, and greater community involvement lead to more dynamic and holistic forms of sustainability that evolve as both local community needs and broader understandings of sustainability change over time.
