Surveying for Mars Analogue Research Sites in the Central Australian Deserts

In anticipation of a future crewed mission to Mars, the international non‐profit organisation known as the Mars Society is currently establishing four mockup bases at which planetary surface operations simulations, equipment testing and personnel training exercises will be conducted over the next decade. These should provide valuable design data for, and raise public awareness about, plans to explore the red planet. One of these bases, which are organised around a habitat of the kind that is likely to serve as shelter for surface‐dwelling astronauts, is to be sited in central Australia under the name MARS‐OZ. To find a suitable location, the Mars Society Australia has conducted a ground‐truth survey of 15 potential sites as practical scientific analogues of the Martian surface, recording these in a specialised database. Each site was assessed on a set of geomorphic, science/engineering, logistic and visual analogue criteria. Six circular exploration zones 200 km in diameter were identified as clusters of the most significant, observed, comparative planetological features. These zones were then ranked to recommend a series of ‘landing sites’, at which future field seasons of exploratory science may be conducted.     

Camelus from the upper pleistocene of Mount Carmel,Israel

A Camelus metapodial, found among the animal bones excavated by Garrod from the Levalloiso-Mousterian of the Tabun Cave (Mount Carmel, Israel), adds to the relatively small number of Camelus finds reported from the Pleistocene of the Near East. The mammal faunas associated with these finds suggest relatively dry open conditions, but not desert conditions. The Tabun specimen is of moderate size, in contrast to the very large Camelus from Far'ah II; two species of camel may thus have been present in the Near East during the Upper Pleistocene.     

Food Deserts: Towards the Development of a Classification

Many people in developed countries fail to consume a healthy diet. This phenomenon has been linked to the contested existence of ‘food deserts’ in the UK, and the occurrence of ‘food insecurity’ in the USA and elsewhere. ‘Food deserts’ remain contested theoretical territory at least partly because no firm definition has been proposed. This paper argues that the barriers to consumption of a healthy diet may be classified according to whether such barriers are financial, physical, or derive from the mental attitude and knowledge of the consumer. The perception of ‘unsupportive food environments’ by some consumers is contrasted with the geographical existence of multiple sources of fresh fruit and vegetables in certain locations. Using a total of 234 semi—structured interviews in various UK locations, qualitative evidence is gathered for the existence of at least ten different types of ‘food desert’. The paper then goes on to show how such a three fold classification may be developed, using a modified ternary diagram, to assess the most appropriate initiatives to tackle ‘food deserts’ and to monitor progress in alleviating their effects.     

BEYOND THE FOOD DESERT: FINDING WAYS TO SPEAK ABOUT URBAN FOOD SECURITY IN SOUTH AFRICA

Urban food security is a significant development challenge in sub‐Saharan Africa. However, the field is currently under ‐researched and under‐theorized. Urban food insecurity, where it is considered, has been viewed through a development studies lens that views food insecurity as a household‐scale problem. There has been significant focus on food deserts in developed countries as one way of engaging with such insecurity. The food deserts research views food insecurity through a social exclusion and food justice lens. This article introduces the food desert concept to provide a conceptual tool to begin to understand the spatial determinants of urban food insecurity, which are not well captured by the existing framings of food security in the region. Using data from a 2008 household food security survey conducted in Cape Town, the paper highlights gaps in the food deserts approach, most significantly its neglect of non‐market sources of food and of household decision‐making processes. The paper therefore concludes by suggesting a new approach which takes the household's assets, abilities and decision‐making as the starting point and overlays this with the market and non‐market foodscapes accessed by these households.
