Cart-ruts have been observed in Mediterranean Basin, Eurasia and Africa. They are rock carved stripes and channels which unexpectedly converge and/or bend, not being useful for transportation use because constant parallelism is not kept. Cart-ruts came first to scholars attention in Malta and Gozo Islands where they are abundant and dated at Bronze or Temple Age of this Archipelago. A big conjoint European investment for Cart-ruts study only got a detailed inventory in several Eurasian and African countries. Age and use of Cart-ruts remains non-discovered: it is admitted that different ages and uses may not be the same for different or even same areas. Azores Archipelago Cart-ruts were left out of this study and we have recently described them at Lanzarote (Canary Islands, Spain) volcanoes tops and slopes and suggested that they could have been useful for space and time measurements. In the present study, Lanzarote is studied and Mt. Mina and Mt. Guardilama mountains Cart-ruts azimuths points to Summer and Winter Solstices sunrises respectively as measured from Quesera/”Cheeseboard” of Zonzamas, which is a prehistoric Guanche lunisolar calendar. Mt. Tenezara Cart-ruts azimuth is pointing towards Equinoxes sunrises, as observed from Zonzamas prehistoric calendar. Thus, a use for measure time and space could be a function for some Lanzarote Cart-ruts. We explain these findings in a prehistoric Guanche aborigine culture context probably common to Atlantic megalithic Bronze Age and to all Canary Islands having prehistoric inter-navigation, because all have similar rock Iberian-Guanche inscriptions and other common cultural traits. Sahara Desert abandoning by people also influenced Mediterranean and Atlantic culture. Probability that 3 out of 7 studied volcano Cart-ruts point to Solstices and Equinoxes by chance is close to zero as calculated by factorial probability methods.

Abstract Opuntia stricta is a cactus species native to the Americas that has been introduced worldwide as a popular ornamental. This species escaped from cultivation and has become invasive in many countries across Africa and Australia, but also more recently in the Mediterranean basin. Large and serious invasions have been reported in Australia, South Africa, Namibia, Yemen, India, Sri Lanka, Madagascar and lately also Spain and some North African countries. It has also become naturalized in many other regions (primarily in Africa and Asia) where it has not yet been recorded as a pest. In South Africa and Namibia large infestations have been reported, mainly in dry savanna bushlands, while in Australia all states are invaded with widespread populations invading southeastern Queensland and northeastern New South Wales. Successful biological control programmes have, however, severely reduced the spread of this species in many areas where introduced, though there continues to be a risk of further introduction through the nursery trade.

Context Specific

In recent years, tens of thousands of young Africans have left the shores of Senegal and other West African countries in small boats headed for Spain's Canary Islands. Most have spent a week or more at sea, and unknown numbers have died in the attempt. Given the danger of the journey, we ask how it could become a large-scale social phenomenon. The analysis focuses on how prospective migrants assess and relate to the risks of migration. We show that risk taking is shaped by context-specific interaction of disparate factors. These include economic obstacles to reaching social adulthood, notions of masculinity, pride and honor, and religion, in the form of sufi Islam.

Abstract Since the decolonisation period, the Sahrāwī in the western Sahara Desert, North Africa have experienced very specific sociopolitical transformations relating to their millennia-old specialisation in nomadic pastoralism. This article examines the effects of such transformations on particular forms of making kin out of others – milk kinship. Various political circumstances have obliged the Sahrāwī to restructure their customary principles of organisation, possibly diminishing these practices. I question the effects of the loss of milk kin – particularly of milk sons – and the strains on customary matrilocal relations in the survival pressure on kinship relying solely upon ‘blood’ sons to replace these ‘missing men’.
