It is widely recognised that access to and supply of modern energy play a key role in poverty alleviation and sustainable development.The emerging concept of energisation seems to capture this idea, and if implemented in its full complexity it should have multiple beneficial effects. To demonstrate this, an economic model is developed for an urban developmental context, drawing on the theory of urban ecosystems and illustrating energy and waste production and consumption issues with current South African data sets. This new understanding of the concept of energisation is then integrated into a local government energy planning process, by means of a checklist for energy planners, covering 18 aspects that between...

The basic principles underlying a four-discrete age group, logistic, growth model for the European lobster Homarus gammarus are presented and discussed at proof-of-concept level. The model considers reproduction, removal by predation, natural death, fishing, radiation and migration. Non-stochastic effects of chronic low linear energy transfer (LET) radiation are modelled with emphasis on Tc-99, using three endpoints: repairable radiation damage, impairment of reproductive ability and, at higher dose rates, mortality. An allometric approach for the calculation of LD50/30 as a function of the mass of each life stage is used in model calibration. The model predicts that at a dose rate of 1 Gy day(-1), lobster population...
