Review:
After
the Second World War, European countries adopted agricultural policies based on
self-sufficiency arguments. In
order to protect farm incomes and increase agricultural development, European
governments imposed a price floor in the agriculture market, essentially
keeping agricultural prices well above world market levels. The subsequent implementation of the
Common Agriculture Policy (CAP), which allowed generous tax allowances and
capital grants to farmers in addition to the price floors, led to overproduction
of agricultural goods. It became
apparent that CAP failed to efficiently increase farm income and solve the
low-income problem. Facing high
European agricultural surpluses and low world prices, the European Union sought
to reform CAP. Though this reform
concentrated on implementing appropriate measures to solve the farmersÕ
low-income problem, it, nonetheless, also acknowledged the relationship between
agricultural expansion and environmental degradation. From an environmental perspective, the CAP reform advocated
the shift from a system based purely on price guarantees to a partially
decoupled system that included direct encouragement of more environmentally
friendly farming.
The
CAP reform package recognized the important role of farmers in protecting
landscape and natural resources, and hence justified direct payments to
agriculture. The main regulation directly
compensated farmers for any loss in income as a result of their agreement to
engage in more environmentally beneficial practices. From an economic point of view, using compensation to tackle
the negative externalities created incentives for the farmers to indulge in
more environmentally friendly farming practices, an approach that promised to
increase the consumer welfare by more than the loss in producer surplus.
This
recognition of the connection between less-damaging farming practices and
environmental benefits led to the creation of the Environmentally Sensitive Area
Agreement (ESA) scheme, a policy based solely on economic incentives. The ESA scheme involves standardized
contracts to buy changes in agricultural production practices through direct
payments to farmers in order to reduce environmental damage. Farmers in specific geographic
locations are targeted based upon the environmental and ecological conditions
of the areas and concentration of people who benefit from the reduction in the
negative externality. These
centrally managed voluntary agreements regulate production practices by either
banning the use of certain activities deemed to produce negative externalities
and/or requiring farmers to engage in such activities that could potentially
produce public goods (Bonnieux et al. 137). Agreement terms vary depending upon the specific regions
involved and the farming practice to be targeted.
Since
the program is voluntary, the main issue with ESA concerns how incentives affect
participation behavior. Even with
sufficient compensation to meet all costs, the participation rate determines
the success of the program.
France
adopted a particular form of the scheme in 1991 to protect the Cotentin
Wetlands in Lower-Normandy, an area covering 37 500 ha. The agricultural revolution after World
War II led to increased land conversion of the wetlands into heavily farmed
areas. Furthermore, intensive
dairy farming altered the pastoral landscape and damaged the permanent pasture lands. Fertilizer use also changed the
landscape of the area in a way that threatened the breeding grounds of native
bird species. Therefore,
agricultural expansion had a dire effect on the delicate environmental
equilibrium of the region.
To
protect this ecologically important area, the government declared it a Natural
Regional Park and assigned an ESA to 8000 ha of the wetland area. The main objectives of the ESA were:
(1) support dairy farming and cattle rearing in the existing grassland area;
(2) conserve wet grassland areas, ditches, drainage channels and their
associated landscape; (3) improve the ecological value of the wet grassland and
associated habitats (Bonnieux et al. 144). The agreement regulated various farming practices that
involved use of pesticides, amount of fertilizer, grazing areas, and
construction of proper drainage systems.
In return, the regulatory authority set an explicit level of direct
payment to be made to individual farmers to meet the costs associated with the
regulations.
By
conducting an empirical analysis, Bonnieux et al. examined the effect of farmer
characteristics on their participation in the ESA scheme. Empirical evidence reveals that age had
a significant impact on participation, with younger farmers willing to join an
ESA. Farm size also had an effect
on participation; farmers with bigger farms had higher enrolment rates. FarmersÕ attitude towards the
environment also contributed to participation rates as farmers who supported
green tourism were more likely to enroll in the ESA program. Other results revealed that enrolment
rates were high in those areas where acreage of the wetland was important and
required some amount of nitrogen as fertilizer. As the scheme allowed farmers to use a considerable amount
of nitrogen as fertilizer (maximum of 30 kg), farmers on this type of wetland
found it easier to comply with the requirements of the scheme.
Though
economic incentives provide a mechanism to protect environmental habitat,
behavioral issues have a large role to play in determining how people would
react to voluntary programs. The
empirical evidence from France on the supply of environmental benefits from
agriculture using ESAs suggests that certain characteristics of farmers
determine the extent to which they would react to the incentives provided to
them. Hence, for future
implementation of such agricultural schemes as ESA, it may well be worthwhile
to investigate how farmersÕ participation rates would affect the amount of environmental
benefit the incentives would provide.
