A paleomagnetic study was carried out in the carbonates and marls of the Liassic member of the Zarzaïtine Formation of the Illizi basin (SE Algeria) deposited in a continental environment. Two ma...
Huge quantities of mineral dust are carried from sources in North Africa to the western Atlantic Ocean every year. Satellite images often show immense dust clouds emerging from the coast of West Afric...
Nanfang Yu, assistant professor of applied physics at Columbia Engineering, and colleagues from the University of Zürich and the University of Washington, have discovered two key strategies that enabl...

Modelling field scale water partitioning using on-site observations in sub-Saharan rainfed agriculture
field scale water partitioning on-site observations sub-Saharan rainfed agriculture
2010/4/7
Smallholder rainfed farming systems generally realise sub-optimal crop yields which are largely attributed to dry spell occurrences during crop growth stages. However, through the introduction of appr...
