Labelled answer diagram:

(a) The equilibrium price is the price at which the quantity of a product that sellers are willing to supply equals the quantity that buyers are willing to purchase. [1] Graphically, it is found at the point where the supply curve and demand curve intersect (point E). At this price, there is neither a surplus nor a shortage in the market.

(b)(i) When supply increases from S1 to S2 (the supply curve shifts to the right):

1. The market price falls because more rice is available at every price level, creating a temporary surplus that pushes the price down. [1]
2. The quantity of rice sold increases because the lower price encourages consumers to buy more. [1]

The new equilibrium is at the intersection of S2 and D, which is at a lower price and a higher quantity than the original equilibrium E.

(b)(ii) Why the increase in supply could reduce individual farmers' income:

1. Although the total quantity sold in the market rises, the price per unit falls due to the increased supply. [1]
2. If the percentage fall in price is greater than the percentage increase in quantity that each individual farmer sells, then total revenue per farmer decreases. [1] This is because each farmer's share of the larger market may not increase enough to compensate for selling at a much lower price. The overall market earns less per kilogram, and individual income drops even as the region produces more rice.

(c) Two factors, other than price, that could cause the demand curve for rice to shift to the right (increase in demand):

1. Increase in population / growth in the number of consumers in the area, creating more demand for the staple food. [1]
2. Rise in consumer income, allowing people to purchase more food or switch from cheaper alternatives to rice. [1]

(d) Three ways a farmer could earn a higher price for rice:

1. Process the rice (milling, grading, and packaging) to add value before sale. [1] Processed, packaged rice commands a premium over raw paddy rice because it is ready for consumers to use.
2. Store rice after harvest and sell during the off-season when supply is low and prices are higher. [1] Harvest time typically brings a glut that depresses prices; holding stock and releasing it later captures seasonal price rises.
3. Sell directly to consumers or restaurants, cutting out middlemen (traders, wholesalers) who take a margin at each stage of the supply chain. [1] Direct sales allow the farmer to capture the full retail value of the product.
