The in situ conservation and the promotion of these varieties is now a major objective for both farmers and researchers. It is one of the tasks set for a cooperative set up to manage agricultural biodiversity sustainably (GDBA), the fruit of a project in Mali, coordinated by CIRAD, which was completed recently. </p> Fri, 25 Jul 2014 16:23:13 +0200 Natural resource management: when games come up with solutions <p> We often think of games as receation for children. However, gaming is a serious learning method in terms of both communication and sharing. This is what researchers from CIRAD and their Senegalese partners tested recently, with a view to drafting natural resource management policy. The participatory method they used combined role-play and simulation board games. It allowed farmers to test their proposals, with a view to ensuring sustainable development without any preconceived scientific or political ideas. The objective was to allow local know-how to be expressed, so as to derive original solutions suited to natural resource use in the uncertain climatic conditions of the Sahel. </p> Fri, 25 Jul 2014 16:05:57 +0200 Cassava: a disease surveillance network in Africa <p> Twenty-eight international organizations recently joined forces to fight cassava diseases in Africa. The network, PACSUN (Pan-African Cassava Surveillance Network) created is setting out to prevent a possible food catastrophe, since cassava is playing an increasingly vital role in the subsistence of people in Africa. </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.
