Section B: 20 marks
Section C: 20 marks
Section A Answers
Q1(a) [1 mark]
Answer: Indonesia (9%).
Teaching note: Lowest withdrawal % means smallest share of internal renewable water used. From Resource 1, Indonesia = 9%, Malaysia = 11%, Vietnam = 28%, Thailand = 42%.
Q1(b) [5 marks]
Mark breakdown: compare across all 4 countries (1m), use comparative language (1m), identify highest/lowest (1m), note mid-range (1m), synthesize pattern (1m).
Answer: Thailand had the highest withdrawal at 42%, followed by Vietnam (28%), then Malaysia (11%), with Indonesia lowest at 9%. Thailand and Vietnam withdraw over a quarter of internal resources, indicating higher pressure on water, while Malaysia and Indonesia use less than 12%, showing greater unused capacity.
Common mistake: listing numbers without "higher/lower than".
Q1(c) [4 marks]
Answer: Developing economies may lack capital to build efficient treatment plants, leading to overexploitation; political priority on growth over environment also limits sustainability. (2 points × 2m)
Teaching: Economic challenge = scarcity of funds / short-term growth focus.
Q2(a) [3 marks]
Answer: Structure has emergent (60 t/ha), continuous canopy (180), understory (40), ground (20). Total mean biomass = 300 t/ha. Dense canopy dominates.
From Resource 2 bar graph.
Q2(b) [4 marks]
Provisioning service e.g., timber (1m). Demand/technology shift: as demand for biofuels rises, crop residues become energy source not waste (3m explanation).
Q2(c) [5 marks]
Extractive industries cause habitat destruction (1m), pollution (1m), invasive species introduction (1m); each reduces regulating services like flood control (2m).
Teaching: Regulating = climate, water flow control.
Q3(a) [2 marks]
Proven = discovered, recoverable under current tech/econ (1m). Speculative = suspected but undiscovered (1m).
Q3(b) [4 marks]
Region A proven-dominated (120 vs 10 spec). Region B more balanced/speculative-heavy (30 proven, 35 spec). A = developed extraction, B = uncertain. (Compare 2 regions × 2m)
Q3(c) [6 marks]
Boserup: tech expands resource base (2m). Malthus: fixed limits (2m). Extent: tech delays but non-renewable finite so partial (2m).
Descriptors: L3 balanced judgement.
Section B Answers
Q4(a) [2 marks]
Dam in X reduces flow to Y irrigation (1m + context 1m).
Q4(b) [6 marks]
Success varies by cooperation (treaties 2m), power asymmetry (2m), data sharing (2m).
Q4(c) [4 marks]
Strategies: rainwater harvesting, efficiency irrigation (2m each).
Q5(a) [2 marks]
Area = 2500 / 500 = 5 km². Working: MWh needed ÷ MWh per km².
Q5(b) [3 marks]
Solar need = 60% × 2500 = 1500 MWh. Area = 1500/500 = 3 km². Steps shown.
Q5(c) [3 marks]
Limitation: intermittent supply / land use conflict (explain 3m).
Section C Essay Answers
Q6 [20 marks]
Descriptors: Knowledge 4, Analysis 8, Eval 8.
Content: renewables reduce fossil dependence (solar/hydro potential 4m), trade-offs: land, social, intermittency (6m), conclusion partial agreement (4m).
Evidence points from syllabus.
Q7 [20 marks]
Success: SDG 6 progress via treaties (6m), challenges: unequal power (6m), conclusion varied (8m).
Marking: L3 evaluative.
