Theme 2A: Effects of urban structures and associated activities.

Urban cities generate considerable potential for ecological disturbance leading to environmental degradation (Programme 2: Anthropogenic Disturbances of Coastal Habitats). In particular, there are problems for organisms on hard and soft substrata because of building jetties, seawalls, pilings, etc. Human disturbances include foraging for bait and food and disposal of wastes. The research to understand ecological changes due to these disturbances is time-consuming and long-term, particularly when experimental analyses of processes during disturbances are planned.

Predicting, measuring and interpreting impacts are hamstrung by poor sampling and analysis - often dictated by inadequate statutory requirements for Environmental Impact Statements. One major problem is that natural ecological assemblages of species vary enormously from time to time and place to place. Thus, even when undisturbed by people, ecological patterns are very different from place to place and change rapidly from time to time.

A thriving coastal city needs massive infrastructure in terms of ports, seawalls, outfalls, etc. Building ports and airports, preventing coastal erosion by building sea-walls, creating recreational facilities such as marinas, swimming-pools and moorings for boats all create potential environmental problems. Among the most important are the loss and fragmentation of natural habitats and the creation of very different artificial habitats.

城市为生态干扰提供了大量潜在诱因，进而引发环境退化（项目2：海岸生境人为干扰（Anthropogenic Disturbances of Coastal Habitats））。具体而言，因建造栈桥、海堤、桩柱等设施，硬质与软质基底上的生物面临诸多生存问题。人类活动造成的干扰包括捕捞饵料与食物以及废弃物排放。针对此类干扰引发的生态变化开展研究，往往耗时且周期漫长，在规划对干扰过程进行实验分析时尤为如此。
对影响的预测、测定与解读常因采样与分析质量不佳而受阻——这一问题往往源于环境影响报告书（Environmental Impact Statements）的法定要求不够完善。核心难题之一在于，自然物种的生态群落会随时间与空间发生显著变化。因此，即便未受人类活动干扰，各地的生态格局也存在显著差异，且会随时间快速演变。
繁荣发展的沿海城市需要港口、海堤、排污口等大规模基础设施。修建港口与机场、通过建造海堤抵御海岸侵蚀、打造游艇码头、泳池及船舶停泊区等休闲设施，均会催生潜在环境问题。其中最突出的问题包括自然生境的丧失与破碎化，以及与原生生态截然不同的人工生境的形成。
