Mitigating the syndromes of desertification: The requirements for transdisciplinary research and information exchange

In developing meaningful mitigation strategies to combat desertification, it is important to address the complex constellation of desertification under different bio-physical, social, demographic, political and economic conditions. In particular, desertification can be described as a cluster of key processes of global change which together form a typical syndrome. A critical reflection on the potential of research to help mitigate desertification will be a useful first step, before addressing the requirements for research partnerships between institutions at local levels and beyond. A practical example from Eritrea, an ecoregion which has been plagued by desertification for many centuries, is given at the end of the paper. It illustrates options for generating the necessary data and developing useful information in order to enhance the impact of research on sustainable development.

Las sibilas de San Telmo

Las Sibilas de San Telmo son doce telas ubicadas en la sacristía de la Iglesia de San Telmo (Buenos Aires, Argentina) que representan a las sibilas Cumea, Helespóntica, Líbica, Cumana, Pérsica, Tiburtina, Frigia, Délfica, Rodia, Eritrea, Sambetea y Samia. Son telas anónimas del siglo XVIII, cuyo origen es desconocido y discutido: pueden ser españolas o cuzqueñas. Cada cuadro consta de tres partes: 1. la imagen de la sibila de frente ricamente vestida; 2. un medallón o tondo, ornado de flores con una escena de la vida de Cristo; 3. en la parte inferior una guarda con el texto bíblico y profético correspondiente al medallón redactado en español. El objetivo de esta comunicación es: a) ubicar esta serie en la tradición sibilina, que en las Divinae Institutiones de Lactancio cristianiza el canon varroniano del siglo I a.C., añadiendo en el s. XVI dos sibilas a las diez de Varrón para emparejar con los doce profetas del Antiguo Testamento; b) establecer los modelos literarios y pictóricos (grabados, tapices o series pictóricas) que pueden haber inspirado la realización de estas telas y su tratamiento en las series sibilinas de México, Bolivia, Brasil y Argentina
