Abstract: This study demonstrates the uses of geographical information system (GIS)and multi-criterion decision-making framework (MCDM) in solving a spatial multi-objective problem of ranking and prioritizing Ugandas national parks for ecotourismdevelopment. The ranking model adopted allows formal analysis of the effects ofalternative weighting schemes and their spatial sensitivity on national park ranking. Theresults show that (1) Ugandas national parks can be arranged and ranked into three sub-groups, and (2) the national parks in the western region of the country are ranked higher

than those in the other regions.

APPLICATION OF GIS IN ECOTOURISM DEVELOPMENTDECISIONS:EVIDENCE FROM THE PEARL OF AFRICA

I. INTRODUCTION

In recent years, researchers have begun to examine how local populations can

direct tourism activities and benefit from them. In the 1980s, alternative forms of tourism

began attracting the interest of governments, communities and scholars alike. These were

given a raft of namesnature tourism, soft tourism, responsible tourism, green

tourism, ecotourism (Schaller, 1999),but all were seen as alternatives to mass

tourism. Among these various labels, the term "ecotourism" has become prominent,

although a consistent definition is by no means found, even among scholars (Schaller,

1999). Most definitions do, however, incorporate concepts associated with sustainable

development. For example, in Sustainable development: Exploring the contradictions,

Redclift (1987) attempted to integrate economic development with ecological

sustainability, and his work has served as a conceptual basis for ecotourism researchers

such as Zurick (1992). Dearden (1991) and Hunter and Green (1995) use the definition

espoused by the World Commission on Environment and Development: "development

that meets the needs of the present without compromising the ability of future generations

to meet their own needs" (WCED, 1987).

Many scholars now agree that ecotourism should require a two-way link between

tourism and environmental conservation (Valentine 1993; Cater, 1994). As the

understanding of the close relationships between tourism and environmental conservation

increases, researchers are calling on ecotourism industry to incorporate economic


3/30

development as a fundamental element of conservation (West and Brechin, 1991:392).

These concerns highlight a critical difference between nature tourism and

ecotourism, at least as the latter term will be defined here. Nature tourism is "based

directly on the use of natural resources in a relatively undeveloped state, including

scenery, topography, water features, vegetation and wildlife" (Healy, 1988: 1). It is also

based upon the desire of people to experience nature in their leisure time. The growing

levels of participation have led to the recognition of sub-markets. Eagles (1995a)

proposed that nature-based tourism has at least four sub-markets (Figure 1), differentiated

according to the travel motives of the tourists.

Figure 1.Tourism sub-markets

Among these subdivisions ecotourism may be the fastest growing tourism sub-

market. The growth of ecotourism primarily involves travel by Europeans and North

Americans to all parts of the world. For example, Eagles and Wind (1994) found that

Canadian ecotour companies visited fifty different countries in 1992. Recently, with

rapidly developing economies in Asia, ecotourists from these countries are entering the

market as consumers. The number of ecodestinations expands with the increases in park

numbers. There is now a worldwide nature travel market, with tourists from many

countries traveling to destinations in many other countries (Zurick, 1992). Ecotourism


4/30

has an idealistic agenda, defined by Drumm (1991: 54) as progressive, educational

travel, which conserves the environment and benefits local communities. Because it is

both succinct and sufficiently ambitious, this definition will be used here.

THE ISSUE

The country in focus in this study, Uganda, is emerging from years of political

instability and entrenched poverty. Before Idi Amin took power in 1971, Uganda had a

major tourism industry, but the industry was crashed with the instability of the country.

Today, tourism is picking up again, and Uganda, with diverse, yet endangered natural

resources has found it preferable to pursue ecotourism for the main reason that tourism is

one of the few products, which it can trade in the international marketplace. Uganda is

also receiving generous funding to support these efforts from international non-

governmental organizations such as the Peace Corps Volunteers (PCV), Germany Animal

Protection Society, CARE International, and from financial institutions such as the World

Bank and the United Nations-based Global Environmental Facility (Ringer, 1996).

The World Bank and United Nations-based Global Environmental Facility (GEF)

have paid ever-increasing attention to the development and conservation potentials of

ecotourism. However, while their previous funded projects did have some ecotourism

components, the GEF set a precedent in early 1995 when it funded a four million US

dollars ecotourism project in Uganda, and wrapped up negotiations for a similar project

in Zimbabwe (Rembert, 1997). The Uganda National Parks (UNP) and the Uganda

Wildlife Tourism Board (WTB), the tourism governing boards in the country were

responsible for allocating the funds (four million US dollars) to four of the ten major

national parks in the country. Faced with simultaneous objectives, UNP and WTB were

II. BACKGROUND

Uganda's tourism industry reflects the extraordinary diversity of the country: a

region of lakes, swamps, dense grasslands, and woodlands, rolling plains, forests and

mountainous areas. Owing to a variety of habitats with abundant grass and landscape,

Uganda supports an incredibly high species biodiversity with a high level of endemism.

In order to protect and effectively manage these invaluable resources on a sustainable

basis, the Uganda National Parks Authority was established in 1952. The organization

presently manages ten national parks: Murchison Falls, Queen Elizabeth, Kidepo Valley,

Lake Mburo, Rwenzori Mountain, Bwindi Impenetrable, Mgahinga Gorilla, Mt. Elgon,

Semuliki, and Kibale national parks. Each of these parks is unique and offers a different

experience for tourists.

As shown in Figure 2, six of the ten Uganda's national parks are located in the

southwestern region of the country in the districts of Kabale, Fort Portal and Kasese.

These districts are characterized by fertile soils, making the agricultural industry vital and

productive in the region. Agriculture has traditionally been the basis of Uganda's

economy (Byrnes, 1992; Ringer, 1996). Since independence in 1962, agriculture has

contributed 60% of the country's gross domestic product (GDP) and 99% of its exports.

Agriculture is estimated to support more than 90% of the population, mostly in producing

food for subsistence or internal trade. Uganda is one of the few African nations that are

self-sufficient in food, despite the almost complete collapse of its economic infrastructure

due to civil war (Byrnes, 1992). The country has a rich and varied agricultural area,

which covers 42% of the total land area of 24,341,100 hectares (60,146,858 acres).

However, only about 21% of the land area is currently under cultivation, mostly in the

three southern regions. Over three-quarters of the countrys total land area receives the

rainfall necessary for intensive cultivation (Uganda, 1990).

III. ECOTOURISM INDUSTRY IN EAST AFRICA

For many of the world's poorest countries, tourism is seen as a means of obtaining

foreign exchange and of developing infrastructure. A country promoting low-impact,

ecological tourism may be able to better avoid the adverse environmental effects from

traditional tourism and the sale of natural resources (Teye, 1987). The link between

environmental protection, international tourism and economic development became

widely recognized in eastern Africa in the early 1970s (Thresher, 1972). Kenya and

Tanzania have well-documented examples of ecotourism industries in eastern Africa.


9/30

9

Starting with only a few thousand tourists in the early 1950s, Tanzanias tourism

increased to 350,000 in 1995 (Friesen, 1995), and Kenyas to 865,300 in 1994 (Anon,

1996). In both countries, the tourism industry is closely tied to world-class systems of

national parks and game reserves. For instance, in Kenya the foreign exchange earnings

from tourism rival sometimes exceed those of agriculture, the other important source of

revenue (Western, 1997). Thus, throughout eastern and southern Africa, park-based

tourism is a very important economic activity.

Kenya has been a successful leader in the development of ecotourism industries

based upon a comprehensive structure of national legislation, policy planning and site

management (Pigram, 1990). Furthermore, since the sustainability of the ecotourism

industry is dependent upon the preservation of environmental quality and biodiversity,

policy makers feel that encotourism can bolster conservation efforts (Division for

Sustainable Development, 1998). Thus, while the potential for negative exploitation of

this emerging industry exists, it is nevertheless seen by many as the lesser of many much

more harmful options available to the world's struggling regions such as Africa (Eagle,

1997).

However, not all tourism development efforts in eastern Africa have been

successful. Ankomah and Crompton (1990) identified five factors inhibiting these

development efforts as negative market image, lack of foreign exchange for capital

development, lack of trained personnel for tourism, weak institutional frameworks for

planning and management and political instability. Sournia (1996) contrasts the

management of park tourism in western Africa to that of eastern Africa. He points out

that even with significant natural resources in western Africa, the tourism levels are well


10/30

10

below those of eastern Africa. Sournia suggests that the reasons for the lower levels of

use include less visible wildlife concentrations, weak national transportation networks,

inefficient hotel facilities, poorly trained tourism staff, weak marketing and a lack of

tourism infrastructure in the parks (Sournia, 1996).

IV. ROLE OF TOURISM IN THE NATIONAL ECONOMY

The impact of tourism in the economy is felt mainly through forward and

backward linkages expressed as demand for goods and services in the agricultural,

textiles, beverage, transportation, and entertainment sectors. Hence, the tourist dollar has

such multiplier effects that its absence would affect the general government revenue

collection.

4.1 Employment in the Tourism Sector

Since tourism is essentially a service industry, it provides relatively more jobs

than any other economic sector. The industry is labor-intensive and, consequently, its

expansion generates more job opportunities than an equivalent expansion in other sectors

of the economy (Teye, 1987). In addition, allied improvements in tourism infrastructure

also catalyze other economic activities. It was estimated that well over 219,000 people

are currently deriving their livelihood from tourism in Uganda (Ringer, 1996).

4.2 Tourism Earnings

Income from tourism contributes to exports and the Gross Domestic Product

(GDP). Foreign exchange earnings have been increasing steadily over the past ten years

representing an appreciable growth rate. While tourism is sensitive to the level of

economic activity in the country, it provides higher and stable earnings than those from


11/30

11

primary products (Ringer, 1996). Tourism earnings tend to increase at a higher rate than

earnings from other export commodities. The earnings incurred are, in turn, used to

offset shortfalls on the visible trading account, and therefore are of critical importance in

the financial reckoning. Tourism contributes greatly to government revenue through

license fees, customs and exercise duty, value added taxes (VAT) on tourism services,

landing fees, passenger service charge, and entry fees to game parks, as well as income

tax levied on employees in the tourism industry. The generated revenues play a pivotal

role in the overall development of a countrys economy (Moore and Carter, 1993).

4.3. Tourism and Development of Infrastructure

The benefits accruing from investments in infrastructure such as hotels and

restaurants, road network and superstructure such as airports, communications, power

and water supply as well as other related public utilities, are widely shared with other

sectors of the economy. Their development enhances the overall development at the

local level and also encourages greater economic diversification. It has been argued by

Schaller (1999) that tourism has larger multiplier effects than any other sectors, since

every unit of tourist expenditure goes through several rounds of income creation and

expenditure before its effect is exhausted. For instance, money spent by a tourist on hotel

accommodation, food and beverages, shopping, entertainment and transportation, does

not stagnate, but provides income to hotel staff, taxi operators, shopkeepers and suppliers

of goods and services. Part of this income is spent on these individuals daily

requirements of goods and services. As a result, money accruing from tourism circulates

through numerous segments of the economy through the multiplier process.

4.4. Tourism and Regional Development

The tourism industry has been described as a major promoter of international

goodwill and understanding (Moore and Carter, 1993), as well a prime means of

developing social and cultural understanding on the local level. Accordingly, foreign

visitors are considered to be the best ambassadors of their respective countries. In view

of the fact that we are living in a global village, the industry contributes significantly to

international commerce and good relation among nations. It is worth noting also that the

development of tourism may serve as an important vehicle for promoting economic

advancement of less developed areas that are not endowed with alternative resources. In

this regard, such developments play an important part in redressing regional development

and income distribution imbalances (Sanchez, 1998).

4.5 Tourism and Cultural Resources

Tourism has always been considered a vital medium for widening the scope of

human interests (Eagles, 1997). It contributes positively to the nurturing and exploration

of cultural heritage of nations. It therefore serves indirectly to improve the individual

cultural understanding of both residents and foreigners, while at the same time

contributing to the gross national product. At the local level, domestic tourism creates an

understanding and appreciation of the attractions thereby, contributing to sustainable

tourism development (Eagles, 1997).

It should be noted also that ecotourists uses local resources and expertise, which

in turn translates into import savings. The use of local resources and expertise also

translates into environmentally sensitive patterns of resource use and local participation

in the tourism industry (Pigram, 1980). Its emphasis on local resources and employment


13/30

13

makes it attractive to developing countries, which, although rich in natural resources are

disadvantaged by rural poverty and the lack of export earnings (Eagles, 1997).

V. METHODOLOGY

This section discusses the data compilation, and presents a brief description of the

multiple criteria decision-making framework (MCDM). In presenting the framework, an

outline of the model as used in this study is provided.

5.1 Data Compilation

The spatial data used in this study include topography, land uses, hydrology,

population distribution, elevation, satellite images, meteorological data, transportation

layers, and ecological species distribution. The non-spatial data includes demographic

and socio-economic data. The spatial data is obtained from United States Geology

Survey (USGSUganda Metadata), African Data Dissemination Services, and Geo

CommunityGeographical Information System Data Deport. Additional spatial data

such as transportation layers are obtained from the World Digital Chart. The non-spatial

data, which includes demographic and socio-economic data, are obtained from the

national parks specific websites (www.newafrica.com/nationalparks), and from the

World Bank.

5.2 Multiple Criteria Decision Making (MCDM)

In most everyday decisions, there exist multiple, conflicting, and sometimes

simultaneous, objectives. MCDM framework helps decision-makers choose among

alternatives by showing the tradeoffs between the criteria, which enables them to make

choices in a rational, consistent, and documentable manner (Zeleny, 1992). Romero and
http://www.newafrica.com/nationalparks/http://www.newafrica.com/nationalparks/http://www.newafrica.com/nationalparks/


14/30

14

Rehman (1989) argued that decision-makers are usually not interested in ranking feasible

alternatives according to a single criterion but strive to find an optimal compromise

among several objectives. In a multiple-criterion problem, human value judgments,

tradeoff valuations, and assessments of the importance of criteria are an integral part of

the evaluation process. The MCDM framework was developed to fill weaknesses

identified in the conventional mathematical programming applications to decision-

making problems (Strager et al., 1997). The multi-criterion problem formulation and

analysis procedure includes the following steps:

1) Defining the desired goals, objectives or purpose of the project. A clear

statement of the recognized problem completes the first step in the decision process

(Gershon and Ducksten, 1983). In this study, the goal is to prioritize and to rank

Uganda's national parks for funding opportunities. The criteria needed to identify the

most suitable national parks include identifying the parks which have, the highest number

of species, wildlife management potential, endangered species, potential to attract more

tourists, and parks that have less susceptibility to encroachment and degradation over the

next decade. With such criterion, the decision-makers could focus their funding priorities

and help ensure that valuable national parks are funded without delay or confusion.

2) Selecting evaluation criteria that can relate technology capabilities for

achieving the desired project goals or objectives (Tecle et al., 1990). A total of ten

evaluation criteria are selected in this study (Table 1). The criteria attempt to build a

loose connection between resource value parameters, such as national park sizes and

composite wildlife value and vulnerability parameters, such as proximity to roads and

developed land uses. Spatial analysis techniques within a Geographic Information


15/30

15

System (GIS) provide the needed integration framework. Once the criteria are selected,

they are traditionally rated among each other using weights, which reflect the decision-

makers preference structure (Tecle et al., 1988).

3) Identifying the alternatives that are candidates for ranking. This study

includes ten national parks as the feasible alternatives to be ranked. Each of these

national parks has certain features or physical characteristics that make it more suitable

for funding than corresponding features found in the other national parks. The ten

national parks included to rank in this project are shown in Figure 2.

4) Selecting performance indices or measurement scales to describe the

alternatives in terms of the given criteria, to reach the desired objectives. In developing

the indices and scales, GIS is used. For each data layer, existing map and data units are

collected from various sources to produce parameter layers in the GIS. If digital spatial

information is not available, maps are acquired, digitized, mosaicked, and registered to

produce the desired data layer. From the GIS database compilation, data could be

assigned to the evaluation criteria. Table 4, shows the conversion of non-numerical

criterion measures into numerical form for evaluation criteria where applicable.

5) Constructing an evaluation matrix of the alternatives vs. the criteria array.

The matrix (Table 5) represents particular values of each national park in terms of the

evaluation criteria. For ease in evaluating the matrix, the elements of the evaluation

matrix are usually expressed in a ratio scale corresponding to a value function on the

interval zero to one (Strager, 1997). Such a transformation is shown as a payoff matrix in

Table 6. This transformation helps to eliminate the influence of widely differing

numerical sizes of the criterion values upon the outcome, while enabling the description


16/30

16

of non-common measurable criteria in a standardized dimensionless scale (Tecle and

Yitayew, 1990).

6)Performing the selection process using one of the MCDM techniques. In this

study, the MCDM model used to rank the national parks in Uganda is compromise

programming. The concept of non-dominance is used in compromise programming to

select the best compromise solution or choice of alternatives. A solution is non-

dominated if there is no other feasible solution that will cause an improvement in the

value of the objective function without making the value of any other objective function

worse.

1.3 MODEL SPECIFICATION

An ideal solution for the compromise programming algorithm as defined by Tecle

and Yitayew (1990), is the vector of objective functions values,

using equation 2:

where,

ijf = the performance index for the values of implementing alternative jA to meet

the desired objectives expressed with respect to the ithcriterion.


17/30

j = the number of alternatives

i = the number of criteria.

Using equations (1) and (2) the decision makers maximum (best) and minimum (worst)

criteria from the payoff matrix is identified.

In a compromise programming procedure, the ideal point serves as a reference

point for evaluating the comparative performances of the alternatives in achieving the

desired objectives (Zeleny, 1982). The alternative that gives a solution Aclosest to the

ideal point is the most preferred. The closeness of a solution to the ideal point *if is

determined using a standardized family of Lp metric values (Tecle and Yitayew, 1990).

According to Romero and Rehman (1989), this type of metric can be very helpful, if used

as a measure for human preferences. The Lp metric as a compromise solution with

respect topis expressed as:

**if = the minimum or worst value for criterion I (Equation 2), and

18/30

18

To solve the multi-criterion problem using the compromise-programming algorithm,

the vector of ideal point values, *if and worst values**

if , are determined using equation

(1), (2) and (3) to compute the Lp distances value from the ideal points. The preferred

alternative has the minimum Lp distance value for eachpand weight set that maybe used

and is the best compromise solution. Obviously, the best compromise solution changes

according to the values of the parameter p and of the weights chosen. The parameterp

acts as a weight attached to the deviations according to their magnitudes. Similarly, iw

becomes the weight for the various deviations signifying the relative importance of each

criterion (Romero and Rehman, 1989). In this project, equation (3) is implemented into

the GIS with a parameterpvalue of 1 while using the payoff matrix data and the criteria

weights imputed from the graphical user interface.

VI. RESULTS

The results of the application of the ranking model, based on iteration by the set

of criteria weights are shown in Figure 3 and Tables 2 and 3. Table 2 presents the

maximum and minimum values estimated using equations 1 and 2, while Figure 3 and

Table 3 present the results of equation 3. The four selected national parks are Murchison

Falls national park, Queen Elizabeth national park, Rwenzori national park, and Lake

Mburo national park. Following the specific objectives and criteria adopted in this study,

the results show that: (1) Among other ranking techniques, Ugandas national parks can

be arranged into three general sub-groups and ranked accordingly in terms of their


19/30

19

specific groups1; and, (2) the national parks in the western region of the country rank

higher than those in the other regions of the country. A possible explanation for the later

finding is that, despite the fertile soils in this region, the topography of western Uganda

(as shown in Figures 4, 5, and 6), characterized by the East African Rift Valley, opens the

region to massive soil loss and land degradation via erosion, which makes traditional

agricultural practices unsuitable. The regions undesirability for agriculture combined

with its sceneries, beautiful weather and a perfect environment for wildlife make the

region more attractive for the ecotourism industry.

CONCLUSION

The study has demonstrated the use of geographical information system and

multi-criteria decision making framework in solving a spatial multi-objective problem of

ranking and prioritizing Ugandas national parks; based on the stated objectives and

criteria for the development of ecotourism industry. The ranking model allowed formal

analysis of the effects of alternative weighting schemes and their spatial sensitivity on

national park ranking. While the problem addressed in this study appears to have been

simple, it demonstrates the applicability of MCDM to similar but more complicated

problems. The advantage of the proposed methodology is that sensitivity analysis can

easily be performed on the results by employing graphical user interface, which allows

the decision-maker to query individual national parks for critical information.

1The ranking technique (sub-grouping other than individual ranking or any other technique) used in this study is a matter of

preference. Given the general objective of identifying four out of the ten national parks, this ranking technique was preferred.
