Production versus protection
The environmental issues that are linked to population and
agriculture are primarily those involved with soil, water, and vegetation. There
are, of course, many other environmental problems facing Sub-Saharan
Africasuch as over-fishing in coastal waters, oil spills, dumping of
hazardous wastes, pollution from urban sewage and industrial waste, land
devastation from surface mining, and so forth. These problems are not, however,
so closely related to rapid population growth and laggard agricultural growth
and therefore are not dealt with here.
Governments must be more determined in developing and
implementing environmental policies aimed at (a) maintaining and restoring, in
the face of increasing consumption demands, the soil, water, pasture, and forest
resources on which agriculture will continue to be based, and (b) preserving
ecosystems and plant and animal species as repositories of genetic
diversity that may underlie future production of many types of products, and as
a national and global heritage. Solving the population and agricultural aspects
of the problem are crucial to curtailing degradation of the natural environment.
Agricultural intensification, farm forestry and fuel wood programs, and sensible
land tenure reform are critical factors, as discussed in Chapter 8. However,
moving from the present situation of rapid deforestation, wetland conversion,
and land degradation to one of stabilizing the area under trees, raising the
efficiency of fuelwood use, preserving much of the remaining wilderness areas,
and reversing the degradation of soils will require an "affirmative action
program" of considerable consequence Such a program will need to comprise a
number of elements beyond those discussed in Chapter 5.
An essential first step is to determine which areas should and
can be maintained as protected areas, and which should be allowed to be
developed for production (cropping, forestry, livestock, fisheries). Criteria
for selecting natural ecosystems for preservation and protection include:
· Biological
importance, notably richness (diversity, numbers) and uniqueness of species and
complexity of the ecosystem: the greater the importance, the more important the
need for full protection.
· Provision of "environmental
services," such as prevention of soil erosion or of destructive flooding,
recharge of aquifers, maintenance of river flow, provision of breeding grounds
for marine life: the greater the value of such services, the greater will be the
importance of protection. Importance for the survival of indigenous peoples and
their livelihood systems, especially of forest dwellers: where indigenous
peoples depend for physical and/or cultural survival on an area remaining
undisturbed, the need for protection becomes imperative.
· Productive potential if
converted to other uses such as cropping or livestock production: the greater
the productive potential under alternative uses, the less viable the decision to
protect fully.
· Current status, i.e., whether
or not the ecosystem is already degraded or spatially constricted to an extent
where it is no longer stable and wildlife populations are no longer sustainable:
the less viable a particular ecosystem, the less viable a decision to protect it
fully.
· Likelihood of success of
preservationwhich depends on the type and degree of present threats (such
as human population pressure) that reduce the likelihood of success versus the
potential for supporting nonexploitative economic activities (such as
ecotourism), which increase the likelihood of success.
These criteria imply tradeoffs. In many cases they will involve
the need to make difficult choices. If one basic objective is to limit the
decline in SubSaharan Africa's total wilderness areas (from their present extent
of 27 percent of the total land area to not less than 23 percent, as postulated
in Chapter 6), these criteria will need to be applied with considerable
stringency. Since natural resource systems, including forests, have multiple
uses, there can be no substitute for some form of planning. Land use plans
should identify conservation areas, parks, areas designated for sustainable
logging, farming areas, pasture and rangeland, as well as areas needed and
suitable for human settlements and physical infrastructure. Agricultural
technology is location-specific in its applications, and land use plans
therefore should identify, in broad terms, the appropriate technologies. Land
tenure issues and fuelwood problems also are location-specificas are many
of the cultural factors that help determine human fertility. Regional plans
should define these, with considerably more weight attached to resource
conservation than in the past.
The widespread skepticism concerning the utility of such plans
is based on the fact that most past attempts at land use planning and regional
planning have not worked well in Sub-Saharan Africa. The reasons included often
excessive complexity of such plans, lack of governmental capacity to prepare and
implement realistic plans, and free quent lack of incentives to cooperate for
the people living in the areas concerned In most cases, and especially those
concerning forest areas, very little, if any, attention was paid to land tenure
issues, identification of appropriate agricultural technology in forest areas,
participation of local people and of the private sector, and provision of
adequate incentives to cooperate for loggers, farmers, hunter-gatherers,
livestock owners, and forest dwellers. Instead, nearly universally applied were
"engineering solutions," implemented by public sector agencies or donorsupported
project management units which sought to manage forest areas independently of
people and of companies operating in the forests.
A different approach is necessaryboth for planning and for
management. It must greatly increase the role of local people and the private
sector in planning and implementation; it must be evolutionary and adaptive,
rather than rigid; and it must be simple to execute. If the role of governments
is confined primarily to providing the legislative backing and to planning and
supervision, land use planning becomes more manageable. And if assistance for
carrying out these more limited functions is provided through the collaborative
mechanisms established for preparing National Environmental Action Plans (NEAPs)
and Tropical Forestry Action Plans (TFAPs), adopting this approach is a
realistic strategy
It is increasingly recognized that maintanance of protected
areas requires the direct involvement of the local and surrounding populations.
It is unrealistic to expect local people to conserve forest and wildlife
resources unless such conservation provides them with clear benefits. The
exclusionary approach so often taken in protected areas in the pest is neither
workable nor sustainable nor equitable. Governments cannot financially afford
and effectively provide the degree of enforcement needed And the local people,
frequently among the poorest, are left to bear the costs of restricted or
prohibited access to resources, exposure to marauding wildlife, and other
disadvantages associated with living on the edge of a closed off territory.
The local people therefore must be active participants in both
planning and implementation of land and resource use. This requires: (a)
appropriate incentives and (b) collaborative planning and implementation of
resource management plans. Incentives are far more likely than governmental
regulation, control, and enforcement to be effective tools for inducing people
to conserve essential stocks of natural resources. The most important incentive
to ensure resource conservation is clearly defined and uncontested resource
ownership: it entails the certainty that the yield or benefits derived from
resources conserved will continue to accrue to the current owners/users and
their descendants, but also that resource degradation will be a cost directly
borne by them. This is best accomplished by ensuring people's ownership of the
land and of the natural resources on that landor, where government
ownership is to continue, by providing legally binding and protected long-term
use rights. Under the right economic conditions, this provides strong and direct
incentives to conserve and to invest in resource conservation or productivity
enhancement. Conversely, loss of ownership or exclusive user rights, or
ambiguities concerning these, create incentives to exploit without regard to
sustainability.
Appropriate resource management plans should be prepared in a
collaborative mannerinvolving the concerned communities, technically
competent government agency staff, and, where they exist and enjoy the local
people's confidence, grassroots organizations and NGOs. Participatory rural
appraisal (PRA) techniques provide very effective tools to do this These
techniques have been developed and refined in the 1980s, evolving from Rapid
Rural Appraisal (RRA) techniques and agroecosystem analyses, to ensure intensive
involvement by the local populations in all aspects of local land use
planningsuch as resource inventory, problem diagnosis, resource use
planning, action plan formulation, etc. (see, for instance, Chambers
1991).
