Urban Problems and Solutions

§Text Passage

1Summary 重點摘要

Growing cities bring housing shortage, congestion and pollution; public housing with new towns, planning and conservation policy are the main answers — but land resumption, relocation and resource allocation spark stakeholder conflicts, eased by consultation, compensation and sustainability principles.

3Step by step Steps

1. Step 1: Housing — shortage and substandard homesHousing is Hong Kong's sharpest urban problem, summarised by the curriculum as insufficient and substandard homes. Population growth outpaces land supply, prices and rents stay high, and grassroots families crowd into subdivided flats and cubicle apartments, with per-capita living space far below other developed cities. For example, a family of four squeezed into a subdivided flat of under fifteen square metres shares kitchens and toilets with neighbours and their children lack study space — poor housing damages health, education and family life, so it is a social problem, not merely one of floor area.
2. Step 2: Congestion — causes and costsCongestion stems from concentrated population and jobs: huge commuter flows crowd limited road space, vehicle numbers keep rising while new roads lag, and major arteries crawl at peak hours. The costs go beyond time: crawling traffic raises emissions, logistics delays lift business costs, and daily life suffers. For example, at morning and evening peaks the queues at the harbour tunnels stretch for kilometres and buses barely move; one traffic accident can paralyse a whole metropolitan area — showing that the existing road network cannot meet ever-growing demand.
3. Step 3: Waste, pollution and environmental healthEnvironmental urban problems include waste, various forms of pollution, and residents' environmental health. Hong Kong dumps over 10,000 tonnes of municipal solid waste in landfills every day and the landfills are filling up; roadside air pollution, noise and light pollution plague dense districts, and residents of old areas bear the greatest environmental health risks. For example, in crowded old districts such as Sham Shui Po, poor ventilation and trapped traffic fumes push up respiratory illness among the elderly and children — environmental problems overlap with poverty in space, so the vulnerable are hit first.
4. Step 4: Housing answers — public housing and new townsThe curriculum's named measures are providing public housing and building new towns. Public rental housing houses the grassroots at rents far below market — about three in ten residents — sparing hundreds of thousands of families from substandard homes; new towns open complete living and working spaces beyond the city. For example, the public housing communities of Sha Tin and Tseung Kwan O have sheltered working-class families for decades and stabilised Hong Kong's labour supply. But the measures have limits: waiting lists run into years and some new towns lack jobs — in answers, give both the achievements and the shortcomings.
5. Step 5: Transport and environment answers — planning firstAnswers to transport and environmental problems rest on urban planning and environmental conservation policy. For transport, high-capacity rail is the public-transport backbone, linked by buses and other modes, with road management guiding travel demand; for the environment, pollution controls, waste separation and recycling, and environmental impact assessment work together. For example, the MTR carries millions of passengers daily; Hong Kong's public-transport usage ranks among the world's highest while car ownership per capita stays low — proof that guiding travel patterns through planning is more sustainable than simply building more roads.
6. Step 6: The conflicts that solutions createSolving urban problems raises several kinds of conflict: land resumption and clearance bring compensation disputes between government and residents or farmers; siting facilities such as landfills and columbaria triggers neighbourhood opposition; and developers versus green groups clash over development and conservation. Stakeholders include government, residents, developers, green groups and professionals. For example, when the Tseung Kwan O landfill extension was proposed, local residents opposed it over odour and health, and the plan had to be revised — stakeholder conflicts can reshape the scale and timetable of policy, exactly the conflict types the curriculum asks you to analyse.
7. Step 7: Managing conflict — and the sustainability ruleConflicts are managed through public consultation, fair compensation and rehousing, and open information for transparency, with sustainable development as the balancing principle: meeting present needs without harming future generations or the environment. For example, after rounds of consultation, new development area plans added in-situ rehousing and farming restoration — adjustments made in response to conflict. The curriculum also warns: if a city long refuses sustainable development, its problems worsen and deepen their impact on people and the environment; people must be able to afford the cost of a sustainable future — and cannot afford the consequences of delay.

8Recap Recap

• Three classes: housing (shortage, substandard), movement (congestion), environment (waste, pollution, health)
• Housing answers: public housing homes about 30% plus new towns; limits are long waits and weak provisions
• Transport and environment answers: rail backbone, pollution controls, recycling and EIA, coordinated by planning
• Solutions create conflicts: resumption, siting, development versus conservation; stakeholders differ
• Managing them: consultation, compensation and rehousing, open information — weigh by sustainability, for delay worsens problems
