Independent Instrumental Case Studies: Allowing for the Autonomy of Cultural, Social and Business Networks in Tanzania

Abstract

Tourism is being utilized as a key economic development tool of the 21st century. Serious concern over the benefit of tourism for the poor has contributed to discussion on community involvement and community participation in contemporary literature. In particular, sustainable development has become a way to address the long-term viability of income and employment in least-developed countries while attempting to preserve traditional customs and culture in the face of globalization. Sustainability refers to finding solutions to poverty without compromising the natural and cultural resource base needed by future generations to pursue their own economic goals. This task requires attention to the economic, cultural and social needs of all groups while focusing on solutions that are also viable for the long term (Bramwell, 2001; Davidson, 2007; Mfaume & Leonard, 2004). It is also important to note that social structures and cultural references vary noticeably within countries and regions. Therefore, three separate, independent instrumental case studies (also known as collective case studies) were conducted in three distinct Tanzanian communities in or around tourism destinations. The objective was to allow for the autonomy of specific cultural, social and business networks to be reflected in the research methodology. Case studies allow for the investigation of constraints to economic participation within real-life experiences, as there is no clear distinction between the phenomenon and the context. Instrumental case studies strive to develop theory, or in this case, facilitate understanding of pervasive problems and do not require typical study populations (Stake, 1995). An instrumental case study is utilized where a ‘particular case is examined mainly to provide insight’ into a phenomenon and the case supports understanding of the phenomenon (Denzin & Lincoln, 2005). The emphasis is placed on specific issues rather than on the case itself. The case in then used as a vehicle to develop a better understanding of the situation or problem (Stake, 2003). Single case studies are ideal for investigating a phenomenon that has not been previously studied and can make a significant contribution to knowledge (Yin, 2003). Since constraints to economic participation within Tanzania have not yet been empirically studied, each individual case study is exploratory in nature. Once the specific case studies were independently derived and themes developed, a cross-case comparison offered insight into reoccurring themes or case-specific constraints. Using an iterative process, the strength of this methodology lies in the inductive approach that provides suggestive rather than definitive analysis (Welch, 1994). The first phase of analysis results in ‘within’ themes specific to a particular region. Using cross-case comparisons, emergent patterns provide similarities and differences between the three communities.
