CIRAD - Actualités / News eng-GB Manioc : un réseau de surveillance des maladies en Afrique <p> Vingt-huit organisations internationales viennent de s'associer pour mieux lutter contre les maladies du manioc en Afrique. Le réseau PACSUN (Pan-African Cassava Surveillance Network) ainsi formé ambitionne de prévenir une éventuelle catastrophe alimentaire puisque, sur le continent, le manioc est de plus en plus central dans la subsistance des populations. </p> Fri, 25 Jul 2014 15:53:38 +0200 CIRAD relaunches scientific cooperation with Ivory Coast <p> During the French President's State visit to Ivory Coast on 17 July, CIRAD and the Centre national de recherche agronomique (CNRA) signed a new general cooperation agreement. The signing marks the resumption of CIRAD's scientific cooperation activities in Ivory Coast, following a period of political unrest in the country. Other agreements with Ivorian research and higher education establishments, professional bodies and funding agencies look set to follow. </p> Fri, 25 Jul 2014 14:45:25 +0200 Agro-ecology and Sustainable Intensification of Annual Crops: the new unit is on line <p> This new CIRAD research unit, the result of a merger between the Annual Cropping Systems (SCA) and Conservation Agriculture and System Engineering (SIA) units, has a wide range of expertise for use in support of ecological intensification, in response to societal demand and development requirements. Its new website, <a href="" target="_self" rel="self" rev="width:100_height:100"></a>, contains the latest news and information on the unit's activities. </p> Thu, 17 Jul 2014 16:27:11 +0200 Global food security: CIRAD and INRA suggest innovative lines of research <p> By the end of the century, food security will be affected by several factors: population growth, climate change, economic unequalities, natural resource shortages, etc. This issue is therefore a major challenge for research, which is why CIRAD and INRA have joined forces to conduct joint, long-term programmes framed by a metaprogramme. The two organizations will be addressing novel issues, at the interface between between more conventional lines of research in this field. The metaprogramme, called GloFoodS (Transitions to Global Food Security), was launched in Montpellier in June 2014. </p> Tue, 15 Jul 2014 16:53:27 +0200 Social structure, a determining factor for crop diversity <p> How do human societies influence crop evolution processes? Researchers from CIRAD and their partners recently demonstrated that sorghum genetic diversity distribution in eastern Kenya was linked to the ethnolinguistic origin of farmers. Taking this into account would make genetic resource collection and characterization programmes more efficienct. This is a major issue for resource conservation. </p> Fri, 11 Jul 2014 17:17:04 +0200 Those potentially lethal bats <p> Bats are accused of all sorts of ills, and even of carrying lethal diseases. They are believed to harbour viruses such as Ebola, Marburg, Nipah, rabies, etc. Even worse, they are suspected of contaminating both animals and humans. </p> Mon, 07 Jul 2014 09:06:38 +0200 Fruit flies are caught in a trap in Réunion <p> Fruit flies are one of the main types of pests found on fruit crops in Réunion. However, the control methods used up to now have two drawbacks: impregnation of the fruit if insecticides are applied directly, and the development of resistance in the flies. In response to these constraints, researchers from CIRAD and their partners tested and proved the efficacy of a new system: mass trapping. It makes it possible to use very small quantities of insecticide, without any direct application on the fruits. The traps contain a sachet of food attractant and a small quantity of insecticide. The researchers concentrated on two fly species for which promising attractants already exist for the females of the species. Their trials served to compare various components of the trap and the possible combinations, using different attractant formulas and traps. The results pinpointed the most effective traps and attractants for use in trapping systems. </p> Wed, 02 Jul 2014 10:42:34 +0200 The 2013 CIRAD Annual Report <p> In 2013, CIRAD chose to look at its priorities and position from the point of view of biodiversity. Many of the research results relayed in the report bear witness to that. The year 2013 was also rich in institutional and strategic changes: a new President Managing Director, renewal of the Science Council, changes in priority lines of research and research platforms, etc. As in previous years, the report includes institutional highlights, results for each priority line of research, indicators, an organizational chart, and maps and addresses of CIRAD installations worldwide. </p> Fri, 27 Jun 2014 15:49:16 +0200 Recycling oil palm organic waste boosts soil fertility <p> In Indonesia, growers use the waste from palm oil extraction to fertilize their plantations, with a positive effect on production. However, what are the long-term effects on soil characteristics? Researchers from CIRAD and their peers showed that continuous applications of the organic matter resulting from that waste improve soil characteristics. This was particularly the case on sandy loam soils, which are less acid than sandy soils. Their carbon and nitrogen contents were multiplied by 1.6 and 1.8 respectively. As regards sandy soils, which are more fragile, the improvement was also clear: carbon and nitrogen contents as much as doubled and acidity was reduced. The only exception was if farmers used inorganic fertilizers, even in small quantities. If so, the beneficial effect was considerably reduced if not wiped out. Provided inorganic fertilizer applications are restricted, farmers can thus maintain the fertility of their soils, thus reducing the environmental impact of their plantations while saving money. </p> Fri, 27 Jun 2014 12:18:39 +0200 The Virtual University of Agro-ecology launches its first on-line training module <p> In response to the need for skills generated by the boom in agro-ecology, establishments belonging to Agreenium (AgrocampusOuest, AgroParisTech, AgroSup Dijon, CIRAD, INPT, INRA and Montpellier SupAgro) and the University of Lorraine (ENSAIA) set up the <strong>Virtual University of Agro-ecology</strong> , which is now launching its first self-study module: &quot;Qu’est-ce que l’agroécologie?&quot;. </p> Wed, 25 Jun 2014 11:03:41 +0200 Regards sur la Terre 2014 <p> The 2014 edition includes a report on the prospects offered by sustainable innovation.

What are the links between these diseases, their transmission, and wildlife? </p> Fri, 20 Jun 2014 16:52:01 +0200 The many facets of rice with CIRAD for the Fête de la biodiversité in Montpellier <p> CIRAD is taking part in the 6th Fête de la Biodiversité organized by the City of Montpellier on 25 and 26 June. Researchers from CIRAD will be introducing visitors to rice biodiversity, notably that of the rice grown in Camargue. </p> Fri, 20 Jun 2014 11:55:36 +0200 Pl@ntNet: lots of improvements to the plant identification app <p> The unique mobile plant identification app Pl@ntNet, which was launched a year and a half ago, is proving to be a big success. And that success looks set to continue with the many improvements made recently: availability on Android, translation into several languages, availability on social networks, optimized navigation, etc. </p> Fri, 20 Jun 2014 11:28:37 +0200 Indian Ocean: mobilizing players in the region to boost food security <p> Backed up by its substantial experience of the Indian Ocean, CIRAD has just signed a general agreement confirming the creation of a regional agricultural research for development (AR4D) platform (PReRAD), in partnership with the Indian Ocean Commission (IOC), the <em>préfecture</em> in Réunion and the Réunion Regional Council. The aim is to mobilize local and regional players more effectively with a view to boosting food security in the Indian Ocean. </p> Mon, 16 Jun 2014 13:05:35 +0200 Week-end vietnamien au Jardin d’agronomie tropicale de Nogent-sur-Marne, 14-15 juin <p> A l'occasion de la célébration de l'année France-Vietnam, le Cirad, la Mairie de Paris et l'Institut français proposent un week-end de découverte du Vietnam au Jardin d'agronomie tropicale de Nogent-sur-Marne.

This is a paradoxical situation for a plant that is propagated vegetatively and was imported from Latin America. Where did this remarkable diversity come from and how do producers make use of it? Researchers from CIRAD and CEFE recently showed that most of the varieties were bred locally from plants resulting from sexual recombination that appeared spontaneously in plots. This is a dynamic process that enables producers to adapt to change, and constitutes an asset for the future. </p> Thu, 05 Jun 2014 17:34:56 +0200
