The idea of ecotourism is being promoted and supported, by growing num
bers of people and groups in different parts of the world, as a major
means of dealing with the damaging effects of tourism. Yet the meaning
of the term varies among different people, projects, and places. Evid
ence from national parks, where this type of tourism has been promoted
for many years, shows that such tourism can cause substantial long-te
rm cumulative changes in environment. Concepts such as ecotourism, gre
en tourism, and sustainable tourism development, are general in their
nature and have to be described, planned, and assessed, in detail on t
he ground in terms of the socioeconomic and environmental conditions a
pplying in different places. In this respect, careful planning and man
agement procedures are needed not only for ecotourism but indeed for a
ll forms of tourism. These procedures and conditions required for tour
ism planning include: 1) setting of goals and objectives; 2) research
to provide a good understanding of relevant ecological and socio-econo
mic systems; 3) concern for efficiency; 4) environmental education; 5)
employee involvement; 6) codes of ethics; and 7) monitoring and asses
sment procedures. A basic principle is the involvement of all affected
parties throughout the life-cycle of ecotourism or other tourism proj
ects. This involvement can be aided by paying more explicit attention
than hitherto to means of facilitating more comprehensive decision-mak
ing and especially to key processes such as understanding, communicati
ng, assessing, planning, implementing, monitoring, and adapting to cha
nge. All concerned parties need to recognize such key steps or process
es in decision-making in order to be prepared to participate efficient
ly and effectively along with other interested persons and groups.
