The review study,"Organic Agriculture in the 21st Century,”is featured as the cover story for theFebruary issue of the journal Nature Plants. It is the first to compare organic and conventional agricultureacross the main goals of sustainability identified by the National Academy of Sciences: productivity,economics,and environment.
Critics have long argued that organic agriculture is inefficient,requiring more land to yield the sameamount of food. It's true that organic farming produces lower yields,averaging 10 to 20 percent less thanconventional. Advocates contend that the environmental advantages of organic agriculture far outweighthe lower yields,and that increasing research and breeding resources for organic systems would reduce theyield gap.Sometimes excluded from these arguments is the fact that we already produce enough food tomore than feed the world's 7.4 billion people but do not provide adequate access to all individuals
In some cases,organic yields can be higher than conventional. For example,in severe droughtconditions,which are expected to increase with climate change in many areas,organic farms can produceas good,if not better,yields because of the higher water-holding capacity of organically farmed soils.
What science does tell us is that mainstream conventional farming systems have provided growingsupplies of food and other products but often at the expense of other sustainability goals.
Conventional agriculture may produce more food,but it often comes at a cost to the environment.Biodiversity loss,environmental degradation,and severe impacts on ecosystem services have not onlyaccompanied conventional farming systems but have often extended well beyond their field boundaries.With organic agriculture,environmental costs tend to be lower and the benefits greater.
Overall,organic farms tend to store more soil carbon,have better soil quality, and reduce soil erosioncompared to their conventional counterparts. Organic agriculture also creates less soil and water pollutionand lower greenhouse gas emissions. And it's more energy-efficient because it doesn't rely on syntheticfertilizers or pesticides.
Organic agriculture is also associated with greater biodiversity of plants,animals,insects andmicroorganisms as well as genetic diversity. Biodiversity increases the services that nature provides andimproves the ability of farming systems to adapt to changing conditions.
Despite lower yields,organic agriculture is more profitable for farmers because consumers are willingto pay more.Higher prices,called price premiums,can be justified as a way to compensate farmers forproviding ecosystem services and avoiding environmental damage or external costs.
51. What do we learn from the conclusion of the author's review study?
A)More resources should be tapped for feeding the world's population.
B)Organic farming may be exploited to solve the global food problem.
C)The long-term prospects of organic farming are yet to be explored.
D) Organic farming is at least as promising as conventional farming.
52. What is the critics' argument against organic farming?
A)It cannot meet the need for food.
B) It cannot increase farm yields.
C )It is not really practical.
D) It is not that productive.
53. What does the author think should be taken into account in arguing about organic farming?
A)Growth in world population.
B)Deterioration in soil fertility.
C) Inequality in food distribution.
D)Advance in farming technology.
54. What does science tell us about conventional farming?
A) It will not be able to meet global food demand.
B)It is not conducive to sustainable development.
C) It will eventually give way to organic farming.
D) It is going mainstream throughout the world.
55. Why does the author think higher prices of organic farm produce are justifiable?
A)They give farmers going organic a big competitive edge.
B)They motivate farmers to upgrade farming technology.
C) Organic farming costs more than conventional farming.
D)Organic farming does long-term good to the ecosystem.
4 The Better Agriculture Group (BAG), which has a divisional structure, produces a range of products for the farming
industry. Divisions B and C are two of its divisions. Division B sells a fertiliser product (BF) to customers external to
BAG. Division C produces a chemical (CC) which it could transfer to Division B for use in the manufacture of its
product BF. However, Division C could also sell some of its output of chemical CC to external customers of BAG.
An independent external supplier to The Better Agriculture Group has offered to supply Division B with a chemical
which is equivalent to component CC. The independent supplier has a maximum spare capacity of 60,000 kilograms
of the chemical which it is willing to make available (in total or in part) to Division B at a special price of $55 per
kilogram.
Forecast information for the forthcoming period is as follows:
Division B:
Production and sales of 360,000 litres of BF at a selling price of $120 per litre.
Variable conversion costs of BF will amount to $15 per litre.
Fixed costs are estimated at $18,000,000.
Chemical (CC) is used at the rate of 1 kilogram of CC per 4 litres of product BF.
Division C:
Total production capacity of 100,000 kilograms of chemical CC.
Variable costs will be $50 per kilogram of CC.
Fixed costs are estimated at $2,000,000.
Market research suggests that external customers of BAG are willing to take up sales of 40,000 kilograms of CC at a
price of $105 per kilogram. The remaining 60,000 kilograms of CC could be transferred to Division B for use in
product BF. Currently no other market external to BAG is available for the 60,000 kilograms of CC.
Required:
(a) (i) State the price/prices per kilogram at which Division C should offer to transfer chemical CC to Division
B in order that the maximisation of BAG profit would occur if Division B management implement rational
sourcing decisions based on purely financial grounds.
Note: you should explain the basis on which Division B would make its decision using the information
available, incorporating details of all relevant calculations. (6 marks)
