The big idea: A stakeholder is any person, group or government with an interest in how water is managed. Different stakeholders want different things from the same river, lake, aquifer or wetland — so managing water almost always creates conflict.
A wetland (marsh, swamp, floodplain, delta, bog) is a place where the land is saturated or covered by water. Wetlands are hugely valuable — they store flood water, clean water, lock up carbon and shelter wildlife — yet they are drained and degraded by farming, building and pollution.
The future of a drainage basin depends on whether its many stakeholders can be balanced sustainably — this is the headline [10] essay of Option A.
Key terms for the stakeholder essay
- Stakeholder — any party with an interest in a water resource (farmers, residents, industry, government, conservationists).
- Conflict — a clash when stakeholders want incompatible things from the same water (e.g. irrigation vs fishing).
- Wetland — saturated land (marsh, swamp, floodplain, delta) — a flood store, water filter, carbon sink and wildlife habitat.
- Ecosystem services — the free benefits wetlands give: flood control, water cleaning, carbon storage, food and recreation.
- Sustainable management — meeting today's water needs without ruining the resource for the future.
- Transboundary basin — a river, lake or aquifer shared across international borders, so no one government controls it.
- Ramsar Convention — the international treaty (1971) under which countries protect wetlands of global importance.
Conflict = competing demands + unequal power: Conflict arises for two reasons: competing demands (the same water is wanted for drinking, farming, energy, fishing and nature) and unequal power (a government or large company can override a small village or a wetland).
For the essay, every stakeholder you name should have a clear want and a clear power — that is what you weigh up.
How this is tested: Before the big essay, a stem will often hand you a stacked bar chart of how a basin's water is shared between sectors (farming, homes, industry, the environment) and ask you to Estimate a value from it or Describe the split — short [1]–[2] reads that warm you up for the [10] essay.
The underlying skill is the same one the essay rewards: map the stakeholders behind those bars — name each sector, state what it wants, and note who holds the power. Read the key and the axis first, then turn the figure into a stakeholder map.
Read the key first. Each colour is a stakeholder — estimate the % each one withdraws, and notice who is left with the smallest share.

| Stakeholder | What they want from the water | Typical conflict |
|---|---|---|
| Farmers | Cheap, reliable water to irrigate crops | Take so much that the river runs low for others |
| Urban residents | Clean, safe piped drinking water | Compete with farms and industry in droughts |
| Industry / energy | Water for cooling, processing or hydropower | Pollute or dam the river, harming users downstream |
| Fishers | A healthy, flowing river and wetlands | Lose catch when water is diverted or polluted |
| Government | Economic growth, flood safety, votes | Favour big schemes (dams) over local needs |
| Conservationists | Wetlands and wildlife protected | Clash with farming and building that drain wetlands |
| Downstream / other countries | A fair share of a shared river | Upstream use leaves too little water flowing on |
Why wetlands sit at the centre of the conflict
- Flood control — wetlands soak up storm water like a sponge, lowering flood peaks downstream.
- Water cleaning — reeds and mud filter out sediment and pollutants, improving water quality.
- Carbon sink — waterlogged peat locks up huge amounts of carbon, slowing climate change.
- Wildlife habitat — they shelter fish, birds and rare species, supporting fishing and tourism.
- The threat — they are easily drained for farmland, buildings and roads, so they are lost fast.
A named wetland under pressure — the Sudd: The Sudd, a vast swamp on the White Nile in South Sudan, shows the conflict in one place. It stores flood water, supports fishing and herding, and shelters huge bird flocks. Engineers once proposed the Jonglei Canal to drain part of it and send the water downstream to Egypt and Sudan for farming. Herders and conservationists opposed losing the wetland; downstream governments wanted the extra water. The clash of stakeholders stalled the scheme — a textbook example of competing demands over a single wetland.

Three case-study clusters give you the named evidence the essay needs. Learn one example from each — a large dam (uneven costs and benefits), a transboundary basin (a shared river crossing borders), and local community water management (small-scale, bottom-up schemes).
| Case | What happens | Stakeholder lesson |
|---|---|---|
| Three Gorges Dam (Yangtze, China) | World's largest dam: power + flood control, but 1.3 million people relocated and habitats drowned | Benefits (energy, government) fall unevenly vs costs (displaced communities, environment) |
| Grand Ethiopian Renaissance Dam (Nile) | Ethiopia dams the Blue Nile for power; Egypt fears losing its water supply downstream | A transboundary basin where upstream and downstream nations clash over a shared river |
| Aral Sea (Central Asia) | Rivers diverted to irrigate cotton; the inland sea shrank, wrecking fishing | Over-abstraction by one sector destroyed a resource shared by several countries |
| Community boreholes & rainwater tanks (rural Kenya/India) | Villages dig wells, harvest rainwater and manage it via local committees | Small, bottom-up schemes give communities a sustainable, affordable supply |
Why dam benefits fall unevenly
- Winners — cities get electricity and flood protection; governments gain growth and prestige.
- Losers — communities are displaced by the reservoir; downstream farmers and fishers lose water and silt.
- Scale matters — national benefits (power, GDP) are often weighed against very local costs (a flooded valley).
- Time matters — benefits can last decades, but the displacement and habitat loss are immediate and permanent.

Name the place, name the data: A generic answer caps in the middle band. Anchor every essay to a named case study with a figure — Three Gorges relocated about 1.3 million people, the Aral Sea lost most of its volume — and say which stakeholder won or lost. Specific places + numbers + stakeholders = top band.
How this is tested — the [10] markband essay: Option A's headline question is a 10-mark markband essay using the AO3 verbs Examine / Discuss / Evaluate / To what extent. Recurring versions: why managing water causes conflict between stakeholders, how the costs and benefits of a dam fall unevenly, how stakeholder pressures make wetlands hard to manage sustainably, and the role of local communities.
Top band (9-10) needs: accurate stakeholder mapping, two or more developed points with a named case study and data, recognition of unequal power and differing perspectives, and a clear, justified conclusion. A one-sided list with no judgement caps at 5-6.
Structure: For / Against / Judgement: Plan the essay as arguments that conflict is hard to resolve (FOR), arguments that it can be managed (AGAINST / counter), then a JUDGEMENT weighing them. Each point is anchored to a named stakeholder and a real example.
