    Abstract Transfrontier Conservation Areas (TFCAs) are widely promoted as an international instrument to achieve certain conservation, cooperation and developmental goals, especially within the Southern African Development Community (SADC). In the SADC context, the status of TFCAs is categorized based on the extent to which international agreements have been signed. These agreements take different forms such as treaties, memorandums of understanding (MoUs), protocols and bilateral agreements. However, the efficacy of agreement-based approaches towards the categorization of TFCAs has been questioned because it does not acknowledge the implementation complexities of TFCAs and lacks a sound conceptual basis. This research evaluates the international TFCA agreements in SADC with a view to recommending a revised categorization. This is achieved by applying Theory of Change (ToC) to a sample of ten signed TFCAs agreements. The results show a lack of enforcement mechanisms, weak provision for implementation and poorly defined objectives. These weaknesses of agreement-based approaches can best be addressed by expanding the categorization of TFCAs to also include the extent of legislative and operational alignment. The revised categorization supports a more complete understanding of TFCA implementation.

    Abstract AbstractProtected area systems are designed in law and policy towards achieving certain policy objectives. These systems rely on legal frameworks that determine how countries designate, declare and manage their protected areas. To date, little research has been conducted on the risks faced by protected area systems. To this end, this paper aims to identify the key risks for protected area systems achieving their objectives. This is achieved through the application of Theory of Change (ToC), which is internationally recognised as the preferred method to identify underlying assumptions and risks within policy and legal frameworks. We achieve this aim through a case study analysis of the South African protected area system as embedded in law and policy. The application of the ToC method identified 25 underlying assumptions and risks which are central to the protected area system achieving its objectives. Understanding these risks allows for a better understanding of the potential failure of the system and how to avoid it. The paper then explores and discusses the identified risks in terms of existing literature and concludes by making recommendations related to further research for the identified risks.

    Abstract Rationale: Drug-resistant tuberculosis transmission in hospitals threatens staff and patient health. Surgical face masks used by patients with tuberculosis (TB) are believed to reduce transmission but have not been rigorously tested.
    Objectives: We sought to quantify the efficacy of surgical face masks when worn by patients with multidrug-resistant TB (MDR-TB).
    Methods: Over 3 months, 17 patients with pulmonary MDR-TB occupied an MDR-TB ward in South Africa and wore face masks on alternate days. Ward air was exhausted to two identical chambers, each housing 90 pathogen-free guinea pigs that breathed ward air either when patients wore surgical face masks (intervention group) or when patients did not wear masks (control group). Efficacy was based on differences in guinea pig infections in each chamber.
    Measurements and main results: Sixty-nine of 90 control guinea pigs (76.6%; 95% confidence interval [CI], 68-85%) became infected, compared with 36 of 90 intervention guinea pigs (40%; 95% CI, 31-51%), representing a 56% (95% CI, 33-70.5%) decreased risk of TB transmission when patients used masks.
    Conclusions: Surgical face masks on patients with MDR-TB significantly reduced transmission and offer an adjunct measure for reducing TB transmission from infectious patients.
