Abstract:
State borders are established through international law via a process called delimitation with
maritime borders often delineated using specific coordinates that map out a state's territorial
extent irrespective of the delineation, there are the effects of maritime security that lead to inter
state conflicts including a case of Lake Nyasa between Tanzania and Malawi. The study
examined the evolution of maritime security on inter-state conflicts in a case of Lake Nyasa
between Tanzania and Malawi. The specific objectives of the study were examined the threats of
maritime disputes between Tanzania and Malawi on Lake Nyasa, evaluated the factors
contributing to maritime security threats in Lake Nyasa and sought to propose potential
interventions for achieving sustainable maritime security on Lake Nyasa. The theoretical
framework explored how historical institutionalism, resource scarcity and conflict theory and
political ecology contribute to these security threats. The historical context, including colonial
treaties and unresolved border agreements, has laid the groundwork for present-day
disagreements. Competition for resources, particularly fish stocks, is exacerbated by a lack of
clearly defined borders and unsustainable fishing practices. Political ecology highlights how
power dynamics and social inequalities shape these issues, with marginalized communities
bearing the brunt of the consequences. The study identifies knowledge gaps in understanding the
role of climate change and non-state actors in maritime insecurity. The study employed a
constructivist-realist approach. The research integrated realist principles concerning national
interests, resource competition and power dynamics with constructivist lenses exploring
historical narratives, treaty interpretations and socio-economic impacts. A mixed methods
approach was adopted, utilizing a case study research design to gather both quantitative and
qualitative data from a sample of n=111 participants in Kyela District, Tanzania. Data analysis
involved SPSS software for quantitative data and thematic analysis for qualitative data. The
research instruments were evaluated for validity and reliability. To ensure validity, expert
feedback was incorporated and the instruments were assessed for relevance and clarity.
Reliability was established through a pilot study using Cronbach's Alpha. Ethical considerations
were paramount throughout the research process. Proper permits were obtained, informed
consent was sought from participants and data confidentiality was maintained. The study found
that the maritime security situation on Lake Nyasa significantly impacts relations between
Tanzania and Malawi. Historical grievances and economic potential of the lake's resources
contribute to the tension. The public is aware of these issues and is affected by the resulting
disruptions to fishing and trade. In conclusion, the study highlights that the maritime security
issues on Lake Nyasa play a pivotal role in shaping Tanzania-Malawi relations, with historical
grievances and resource competition intensifying tensions that disrupt local livelihoods. The
study recommends increased diplomatic efforts, establishment of a Joint Boundary Commission
and public education campaigns to foster peace. The study also recommends that maritime
security agencies enhance patrols, develop joint initiatives, invest in surveillance technologies
and train personnel. Collaborative efforts on environmental protection are crucial. Further
research is suggested on the role of international law and political dynamics in exacerbating or
mitigating maritime security threats. The study highlights the need for effective conflict
resolution and peacebuilding strategies.
