    Citizen Science - Mammal Map
    (2014-09-12) Hoffman, Tali; Neary, Tim
    In this radio broadcast, Tali Hoffman explains the purpose and scope of MammalMAP - an online platform which aims to update the distribution records of all African mammal species - and how citizens all over Africa can contribute by sending in photos of animals in conjunction with their location. Tali discusses capacity and services offered by the platform, the ways in which this information is being used, and the ethical considerations required and the measures taken to prevent abuse of such a resource, such as poaching.

    Climate change vulnerability and risk analysis in the Bobirwa sub-district, Botswana: towards Improving livelihood adaptation to climate
    (2016-04-01) Chandapiwa, Molefe; Hillary, Masundire
    In November 2015, ASSAR ’s southern Africa researchers– from the University of Botswana, The University of Cape Town, University of Namibia and Oxfam GB– conducted a two-day Vulnerability Risk Assessment (VRA) workshop in Bobirwa, Botswana. The workshop was attended by various government officials, Village Development Committee members, local community members, and representatives from farmer committees, collectively known as the VRA Knowledge Group. The VRA process aims to develop a common understanding among various stakeholders (government officials, village committees and local communities) of the main hazards and issues affecting those living in a given social-ecological landscape. This is done so as to design measures that reduce risk, enhance wellbeing and promote resilience to hazards in the landscape.

    Landscape requirements of a primate population in a human-dominated environment
    (BioMed Central Ltd, 2012) Hoffman, Tali; O'Riain, M Justin
    INTRODUCTION: As urban and rural land development become widespread features of the global landscape so an understanding of the landscape requirements of displaced and isolated wildlife species becomes increasingly important for conservation planning. In the Cape Peninsula, South Africa, rapid human population growth, and the associated urban and rural land transformation, threatens the sustainability of the local chacma baboon population. Here we analyse spatial data collected from nine of the 12 extant troops to determine their population-level landscape requirements. We use hurdle models to ascertain the key landscape features influencing baboon occurrence and abundance patterns on two hierarchical spatial scales. RESULTS: Both spatial scales produced similar results that were ecologically reliable and interpretable. The models indicated that baboons were more likely to occur, and be more abundant, at low altitudes, on steep slopes and in human-modified habitats. The combination of these landscape variables provides baboons with access to the best quality natural and anthropogenic food sources in close proximity to one another and suitable sleeping sites. Surface water did not emerge as an influential landscape feature presumably as the area is not water stressed. CONCLUSIONS: The model results indicate that land development in the Cape Peninsula has pushed baboons into increasingly marginal natural habitat while simultaneously providing them with predictable and easily accessible food sources in human-modified habitats. The resultant spatial competition between humans and baboons explains the high levels of human-baboon conflict and further erosion of the remaining land fragments is predicted to exacerbate competition. This study demonstrates how the quantification of animal landscape requirements can provide a mechanism for identifying priority conservation areas at the human-wildlife interface.
