Year 10 SQA Geography: Case Study Drill | Year 10 SQA 地理：案例分析实战演练

📚 Year 10 SQA Geography: Case Study Drill | Year 10 SQA 地理：案例分析实战演练

To succeed in SQA Geography, you must move beyond memorising facts. The exam requires you to apply knowledge to real-world case studies, analysing causes, impacts, and management strategies. This practical drill will guide you through a detailed case study of Bangladesh’s coastal communities facing climate-induced migration. You’ll learn how to structure answers, use geographical terminology, and interpret data. By the end, you’ll be confident tackling any case study question.

要在SQA地理考试中取得成功，你必须超越死记硬背。考试要求你将知识应用于实际案例，分析原因、影响和管理策略。本实战演练将带你深入了解孟加拉国沿海社区面临气候引发的迁移这一详细案例。你将学习如何组织答案、使用地理术语和解读数据。最后，你将能自信应对任何案例分析题。

1. Understanding the Case Study Approach | 理解案例分析的方法论

A case study in geography is not just a story; it’s a structured analysis of a specific place or issue. SQA examiners want you to demonstrate that you can apply concepts like ‘push-pull’ theory, sustainability, and hazard management to real situations. You need to identify the location, explain processes, explore effects on people and the environment, and evaluate responses.

地理案例分析不仅仅是一个故事，而是对特定地点或问题的结构化分析。SQA考官希望看到你能够将‘推拉’理论、可持续性和灾害管理等概念应用于实际情况。你需要确定地理位置，解释过程，探讨对人和环境的影响，并评估应对措施。

A strong case study answer uses facts and figures as evidence. For example, you might state the population density of Dhaka or the height of storm surges. Always link evidence back to the question. Avoid simply describing; instead, explain why something happens and what the consequences are.

一个出色的案例分析答案要使用事实和数据作为证据。例如，你可以说明达卡的人口密度或风暴潮的高度。始终将证据与问题联系起来。避免单纯描述，而要解释为什么会发生以及后果是什么。

2. Case Study Focus: Bangladesh’s Coastal Crisis | 案例聚焦：孟加拉国的沿海危机

Bangladesh, located on the Bay of Bengal, is one of the world’s most densely populated and low-lying nations. Its extensive coastline is extremely vulnerable to tropical cyclones, sea-level rise, and river flooding. This makes it an ideal case study for examining the interactions between physical geography and human migration.

孟加拉国位于孟加拉湾，是世界上人口最稠密、地势最低洼的国家之一。其漫长的海岸线极易受热带气旋、海平面上升和河流洪水的影响。这使其成为研究自然地理与人口迁移相互作用的理想案例。

We’ll look specifically at the communities in the southern districts like Khulna and Barisal. Here, millions of people depend on agriculture and fishing, but environmental changes are pushing many to leave their ancestral lands. The government often classifies these people as ‘climate refugees’, though international law does not yet recognise that term.

我们将特别关注南部库尔纳和巴里萨尔等地区的社区。在这里，数百万人依赖农业和渔业为生，但环境变化迫使许多人离开祖祖辈辈的土地。政府常将这些人归类为‘气候难民’，尽管国际法目前尚未承认这一术语。

3. Geographical Context: Location and Physical Features | 地理背景：位置与自然特征

Bangladesh lies between 20° and 26°N latitude, with the Tropic of Cancer running through its centre. Most of the country is formed by the Ganges–Brahmaputra–Meghna delta, the largest delta in the world. The land is flat, with an average elevation of less than 12 metres above sea level, making it highly susceptible to flooding.

孟加拉国位于北纬20°至26°之间，北回归线穿过其中心。该国大部分地区由恒河—布拉马普特拉河—梅格纳河三角洲构成，这是世界上最大的三角洲。地势平坦，平均海拔低于12米，极易遭受洪水侵袭。

The coastal zone includes the Sundarbans, the world’s largest mangrove forest, which acts as a natural barrier against storm surges. However, mangrove deforestation and rising salinity are reducing this protection. The monsoon climate brings heavy rainfall from June to October, causing rivers to swell.

沿海地区包括孙德尔本斯，这是世界上最大的红树林，充当抵御风暴潮的天然屏障。然而，红树林砍伐和盐度上升正在削弱这种保护。季风气候在6月至10月带来强降雨，导致河流水位上涨。

4. Climate Hazards: Cyclones and Rising Seas | 气候灾害：气旋与海平面上升

Bangladesh experiences severe tropical cyclones almost every year. In 2007, Cyclone Sidr killed over 3,400 people and caused immense damage. More recently, Cyclone Amphan in 2020 affected millions. These storms generate storm surges up to 5-6 metres high that can travel far inland across the flat terrain.

孟加拉国几乎每年都遭受严重的热带气旋侵袭。2007年，气旋锡德造成3400多人死亡，带来巨大破坏。最近的2020年气旋安攀影响了数百万人。这些风暴产生的风暴潮高达5至6米，可沿平坦地形深入内陆极远。

Sea-level rise due to climate change is an existential threat. The IPCC projects a rise of up to 1 metre by 2100. Even a 0.5-metre rise would permanently inundate about 10% of Bangladesh’s land area, displacing over 15 million people. Saltwater intrusion into groundwater and farming soil is already ruining rice paddies and freshwater supplies.

气候变化导致的海平面上升是一个生存威胁。IPCC预测到2100年海平面上升可达1米。即使仅上升0.5米，也会永久淹没约10%的孟加拉国土地，使超过1500万人流离失所。咸水入侵地下水和耕种土壤已在破坏稻田和淡水供应。

5. Migration Drivers: Push and Pull Factors | 迁移驱动因素：推力和拉力

Push factors in coastal Bangladesh include loss of agricultural land due to salinisation, destruction of homes by cyclones, and chronic poverty. Frequent flooding also leads to waterborne diseases like cholera, which push families to seek safer living conditions. Psychological stress and lack of future prospects are also significant.

孟加拉国沿海的推力因素包括盐碱化导致的农田损失、气旋摧毁家园以及长期贫困。频繁的洪水还引发霍乱等水媒疾病，迫使家庭寻求更安全的生活条件。心理压力和对未来的绝望也是重要因素。

Pull factors draw people to urban areas, primarily Dhaka and Chittagong. These cities offer employment in the ready-made garment sector, construction, and informal markets. Rural migrants believe cities provide better education and healthcare for their children. The perception of a secure life away from cyclones is a powerful magnet, even though urban slums carry their own risks.

拉力因素将人们吸引到城市地区，主要是达卡和吉大港。这些城市提供成衣业、建筑业和非正规市场的就业机会。农村移民认为城市能为子女提供更好的教育和医疗。远离气旋的安稳生活想象是一个强大的吸引力，尽管城市贫民窟也存在自身风险。

6. Impacts on People and the Environment | 对人类和环境的影响

The environmental impacts in source areas include extensive coastal erosion and loss of biodiversity as mangroves are cleared for fuel or shrimp farming. Abandoned farmland becomes unproductive wasteland. In urban destination areas, rapid unplanned growth leads to severe air and water pollution, as well as encroachment on wetlands.

来源地区的环境影响包括广泛的海岸侵蚀，以及由于砍伐红树林作为燃料或用于虾养殖而导致的生物多样性丧失。被遗弃的农田变成了无法耕种的荒地。在城市目的地，快速无序扩张导致严重的空气和水污染，并侵占湿地。

Socially, migration disrupts community structures. Women often become heads of household when men migrate first, but they may face greater vulnerability to exploitation. In cities, overcrowded slums like those in Dhaka’s Korail area lack sanitation, clean water, and secure tenure. Crime and child labour are widespread. Yet, remittances sent home help support families and can fund education.

从社会层面看，迁移破坏了社区结构。当男性先迁移外出时，女性往往成为户主，但她们可能更容易受到剥削。在市区，像达卡科拉伊尔地区这样过度拥挤的贫民窟缺乏卫生设施、清洁水和安居保障。犯罪和童工现象普遍存在。但寄回家的汇款有助于维持家庭生计和资助教育。

Economically, rural areas suffer labour shortages, reducing agricultural productivity. Urban economies struggle to absorb the influx, leading to high unemployment and pressure on infrastructure. However, the garment industry benefits from a large pool of low-cost labour, contributing significantly to national exports.

经济上，农村地区因劳动力短缺而降低农业生产力。城市经济难以吸纳大量涌入人口，导致高失业率和
