Review of water energy food nexus in Africa : Morocco and South Africa as case studies

Abstract: The population of African continent is significantly increasing which has given rise to societal, economic and environmental changes. This will generate an increase in demand for food, water and energy. Thus, strategies for sustainable management of natural resources need to be adopted urgently in order to match the future needs and to ensure sustainable development on the continent. The Water Energy Food (WEF) nexus is one the avenues for studying the current and future interactions and interdependencies of the WEF sectors under different scenarios and challenges in the effort towards establishing sustainable use of natural resources. Policies around the nexus approach are few or absent at the continental and country levels. This paper is a first review on the adoption of the Nexus in two model African countries, Morocco and South Africa. The review compares the water, energy and food sectors and the related national policies, plans and frameworks. The data related to the WEF Nexus revealed key difficulties of availability in both countries. A comparative analysis of the situation in both countries demonstrated differences in policies relating to the WEF Nexus across the sectors: water, energy, and agriculture. Additionally, the paper explores the relevance of technology-assisted frameworks for the WEF nexus and also analyzed risks to agriculture and food security in the context of the reviewed countries

Tekoporã

Asunción (abril 2013): el mes dedicado a los Pueblos Indígenas estuvo centrado en torno a dos actividades principales: la exposición “Tekoporã”, curada por Ticio Escobar que se inauguró el viernes 12 de abril de 2013, y el seminario “Los mundos posibles”, que se desarrolló a lo largo de inco semanas, con una serie de producciones audiovisuales, que contaron con la presencia de los realizadores y algunos de los protagonistas, y con una serie de sesiones teóricas con algunos de los mayores especialistas en la materia

Host Range and Genetic Diversity of Arenaviruses in Rodents, United Kingdom

During a study to extend our knowledge of the host range and genetic diversity of arenaviruses in Great Britain, 66 of 1,147 rodent blood samples tested for antibody, and 127 of 482 tested by PCR, were found positive. All sequences most closely resembled those of previously identified lymphocytic choriomeningitis virus

The poetics of indigenous radio in Colombia

In 2002, 14 indigenous radio stations began operating in Colombia reaching 78.6 percent of the national indigenous population. Colombian indigenous radio stations are shaped by intense deliberations among each indigenous people about the poetics of information and communication technologies, understood as the exploration of the specific sets of social, cultural and political relations in which each radio station would exist if brought into each indigenous territory. Colombian indigenous peoples' appropriation of information and communication technologies is framed by new legislative frameworks made possible by the Colombian constitutional reform of 1991, by indigenous peoples' critique of Colombian mainstream media and, more significantly, by discussions among indigenous peoples about the adoption of radio — what we call a poetics of radio.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Impact of temperature on lethality of kiwifruit puree pasteurization by thermal and microwave processing

The use of pasteurization units (PU) as a measure of the lethal effect of processes was proposed with the aim of comparing conventional and novel thermal technologies. Kiwifruit puree was subjected to microwave (1000 and 900 W) and conventional (97 C) heating. Processing conditions of the treatments were chosen to simulate a pasteurization treatment. The temperature profiles of the samples during processing were recorded at different positions. The coldest and hottest spots of the product were identified and the associated PU numbers were calculated. A significantly (p < 0.05) higher thermal load was necessary in order to stabilize the kiwifruit puree under conventional (19.27 min) than microwave heating mode (0.003e8 min) at any of the conditions studied. The higher effectiveness of microwave heating could be attributed to non-thermal effects associated with this technology.The authors thank the Ministerio de Educacion y Ciencia for the financial support given through Projects AGL 2010-22176 and AGL 2010-22206-C02-01 and the grant awarded to the author Maria Benlloch.Benlloch Tinoco, M.; Martínez Navarrete, N.; Rodrigo Aliaga, MD.

Predicting Phenotypic Diversity and the Underlying Quantitative Molecular Transitions

During development, signaling networks control the formation of multicellular patterns. To what extent quantitative fluctuations in these complex networks may affect multicellular phenotype remains unclear. Here, we describe a computational approach to predict and analyze the phenotypic diversity that is accessible to a developmental signaling network. Applying this framework to vulval development in C. elegans, we demonstrate that quantitative changes in the regulatory network can render ~500 multicellular phenotypes. This phenotypic capacity is an order-of-magnitude below the theoretical upper limit for this system but yet is large enough to demonstrate that the system is not restricted to a select few outcomes. Using metrics to gauge the robustness of these phenotypes to parameter perturbations, we identify a select subset of novel phenotypes that are the most promising for experimental validation. In addition, our model calculations provide a layout of these phenotypes in network parameter space. Analyzing this landscape of multicellular phenotypes yielded two significant insights. First, we show that experimentally well-established mutant phenotypes may be rendered using non-canonical network perturbations. Second, we show that the predicted multicellular patterns include not only those observed in C. elegans, but also those occurring exclusively in other species of the Caenorhabditis genus. This result demonstrates that quantitative diversification of a common regulatory network is indeed demonstrably sufficient to generate the phenotypic differences observed across three major species within the Caenorhabditis genus. Using our computational framework, we systematically identify the quantitative changes that may have occurred in the regulatory network during the evolution of these species. Our model predictions show that significant phenotypic diversity may be sampled through quantitative variations in the regulatory network without overhauling the core network architecture. Furthermore, by comparing the predicted landscape of phenotypes to multicellular patterns that have been experimentally observed across multiple species, we systematically trace the quantitative regulatory changes that may have occurred during the evolution of the Caenorhabditis genus
