The role of UK retailing in urban regeneration

This research examines the role of retailing in urban regeneration nationally and locally in the UK. The research uses data at a national level and local shopping centre case studies to examine the employment and property impacts of retailing. Focusing on schemes built during the first part of the 1990s it shows that retail can bring employment and economic benefits to town centres, but that the impact on the inner city should not be overlooked. Valuable lessons can be learned from the experience of centres built during this period of recession, and new challenges such as eCommerce now face these centres and others being developed today. The research examines the multiplier effect of retail regeneration schemes nationally using National Accounts data, and the local property and employment impacts of shopping centre schemes in the case study towns of Aberdeen, Bristol, Norwich, Bromley, Worcester and Leicester. The report includes valuable statistical sources, a full literature and policy review and will be of interest to those involved in property investment, regeneration and planning. The research was funded by the Office of Science & Technology and the Harold Samuel Educational Trust.

Role of marine biology in glacial-interglacial CO2 cycles

It has been hypothesized that changes in the marine biological pump caused a major portion of the glacial reduction of atmospheric carbon dioxide by 80 to 100 parts per million through increased iron fertilization of marine plankton, increased ocean nutrient content or utilization, or shifts in dominant plankton types. We analyze sedimentary records of marine productivity at the peak and the middle of the last glacial cycle and show that neither changes in nutrient utilization in the Southern Ocean nor shifts in plankton dominance explain the CO2 drawdown. Iron fertilization and associated mechanisms can be responsible for no more than half the observed drawdown.
