The two authors recall the key role of science in reconciling climate change mitigation and the development of southern countries. In particular, they point out the need for studies and detailed empirical data on the range of local situations locales, which are hidden by overall forecasts of average temperature rises. </p> Mon, 20 Jul 2015 17:54:57 +0200 Les enjeux de la conférence de Paris. Penser autrement la question climatique <p> A special issue of <em>Natures Sciences Sociétés,</em> a journal co-published by CIRAD, to mark the climate conference to be held in Paris in December 2015. The success of the conference will depend not only on the commitment - or lack of it - of the 195 States present, but also on our capacity to make in-depth changes to the way in which scientists - climate specialists and economists first and foremost - and Policy-makers have historically &quot;framed&quot; the climate issue. Twenty-three years on from the signing of the Rio Convention, this Framework has shown its limitations. This issue, in which all the articles are on open access, suggests various possible ways of overcoming this, by putting the latest research to good use. </p> Fri, 17 Jul 2015 11:35:17 +0200 Bt cotton: seed mixtures are less effective than external refuges as regards resistance <p> Growing cotton that has been genetically modified to produce insecticidal toxins inevitably leads tpo the development of resistance in the target insects. To slow down the phenomenon, seed firms can now supply farmers with ready-to-use mixtures of modified and non-modified seeds, which are intended to serve as refuges. However, are these refuges, inside crop plots, as effective as the external refuges recommended to date? Researchers from CIRAD and the University of Arizona recently demonstrated that these mixtures carry risks, since they increase the dominance of insect resistance, if the insects are capable of moving from one plant to another. </p> Fri, 17 Jul 2015 11:31:46 +0200 The threats and assets of viruses for animal health <p> SAVE THE DATE - From 31 August to 3 September 2015, Montpellier's Corum Centre will be hosting the Xth International Congress for Veterinary Virology, ESVV 2015, organized by CIRAD and supported by a public debate on the topic of viruses: former enemies? new friends?. </p> Thu, 16 Jul 2015 11:15:46 +0200 Laurence Tubiana: "Soil restoration is a major factor for climate" <p> At the 25 June meeting in Montpellier of the CIRAD Board of Trustees, of which she is a member, Laurence Tubiana, French ambassador for climate negotiations and special representative for the 2015 Paris Climate Conference, stressed the role of research, by CIRAD and its partners, in relation to such events. Selected highlights. </p> Fri, 10 Jul 2015 15:39:55 +0200 Expo Milano 2015 - Tsetse fly eradication in Senegal wins a Best Practice award <p> In Senegal, tsetse flies have now been almost totally eradicated in the Niayes region. This spectacular result has just been given a Best Practice award at the Milano 2015 universal exposition. Animal trypanosomiasis, which is transmitted by tsetse flies, is a huge threat to livestock farms in sub-Saharan Africa. The project centres on using traps impregnated with insecticides and releasing sterile males in the region. Tsetse flies have now been totally eradicated in 20% of the zone and the number of insects in the rest of the target zone has been cut by more than 95%. In view of its socioeconomic impact, the project could eventually transform the lives of many local livestock farmers. </p> <p> The project is the fruit of a partnership between CIRAD, the Directorate of Veterinary Services in Senegal, the Institut Sénégalais de Recherches Agricoles (ISRA) and the Joint FAO/AIEA Division of Nuclear Techniques in Food and Agriculture. </p> Wed, 08 Jul 2015 16:43:11 +0200 Initiation à la protection agroécologique du manguier à la Réunion <p> This book illustrates the agro-ecological dynamic that has emerged in recent years in Réunion, enabling the development of organic farming on the island. </p> Mon, 06 Jul 2015 12:38:30 +0200 Cocoa agroforests: redistributing vegetation serves to regulate pest and disease attacks <p> Cocoa agroforests are complex agrosystems similar to natural ecosystems. That complexity is an asset in terms of managing cocoa pests and diseases. But how does it serve to regulate their presence and minimize the intensity of their attacks? Based on studies in Cameroon and Costa Rica, researchers from CIRAD and their partners recently demonstrating the predominant role of the spatial structure of such agroforests in terms of regulation. </p> Mon, 06 Jul 2015 11:14:52 +0200 Hervé Le Treut: "Adaptive, local and collective agriculture, the best way for farmers to cope with the risks linked to climate change" <p> The climatologist Hervé Le Treut, member of the IPCC and the French Académie des sciences, explains how global warming, which is now beyond question, has an adverse impact on yields, generating risks for farmers. His recommendations: build adaptive, locally rooted farming systems and anticipate the future. </p> Thu, 02 Jul 2015 15:30:36 +0200 Climate and Agriculture on the agenda for a conference: "Our Common Future Under Climate Change" <p> Agriculture has a major role to play in strategies for adapting to climate change and mitigating greenhouse gas emissions. This increasingly oft-heard message will be part of the debate at a major international conference: &quot;Our Common Future Under Climate Change&quot;. The global scientific community, including CIRAD, is expected at the conference in Paris, from 7 to 10 July 2015, ahead of the upcoming UN talks (COP21). </p> Thu, 02 Jul 2015 11:38:04 +0200 Remote sensing: very high-resolution satellite images are available to public-sector players <p> CIRAD, the CNES, the CNRS, the IGN, the IRD and IRSTEA are to receive very high-resolution images from the SPOT 6-7 satellites for a five-year period. To this end, the six organizations signed a contract on 18 June 2015 with Airbus Defence &amp; Space. The images will be made available to the national players in charge of implementing public policy, and the scientific community. They will cover France's national territory, including its overseas regions, and may also concern zones in southern countries. </p> Fri, 26 Jun 2015 17:26:03 +0200 Agritrop is now an institutional open archive <p> The CIRAD publications base, Agritrop, was recently converted into an institutional open archive. With more than 90 000 references and 12 000 full-text documents, this new version gives open, free access to CIRAD's written scientific output. </p> Thu, 25 Jun 2015 13:10:41 +0200 Agro-ecology: France and China are looking into modes of cooperation <p> Agriculture has a crucial role to play in the face of climate change. Ahead of the talks scheduled during the 21st climate conference (COP21 – Paris 2015), CIRAD has made an active contribution, alongside INRA, to a Franco-Chinese conference on agro-ecology. The main topics chosen for cooperation are: carbon sequestration in the soil to mitigate greenhouse gas emissions, and the use of genetic resources to adapt species to drought. Research practices common to France and China and specific to agro-ecology also emerged from the discussions: integrating local knowledge into innovation processes and the need for modelling. </p> Thu, 25 Jun 2015 11:12:55 +0200 Sugarcane: a crop that also produces energy <p> With the growth in demand for biofuels, using sugarcane by-products such as bagasse and ethanol could become more cost-effective. However, it is necessary to determine the conditions in which production could be both optimum and compatible with high sugar yields. A team from CIRAD, working with the eRcane firm, embarked upon a complex, novel study of the entire production chain, from plot to mill, to determine the impact of production factors on biomass yield and quality, and on aerial biomass distribution between food and energy production. </p> Tue, 23 Jun 2015 17:32:03 +0200 Voies lactées - Dynamique des bassins laitiers entre globalisation et territorialisation <p> Agricultural operations and territories, which are subject to the forces of globalization and territorialization, are evolving. But how? And what are the prospects? This book analyses the reconfigurations under way in seven dairy basins worldwide, in France, Brazil, Uruguay, Senegal and Vietnam. </p> Fri, 19 Jun 2015 15:59:28 +0200 Coffee: more vigorous plants contain fewer toxins against leaf miners <p> </p> <p> In the hope of controlling leaf miners, a team from CIRAD has conducted research into the genetic modification of coffee trees using <em>Bacillus thuringiensis</em> genes that code for insecticidal endotoxins. On testing the modified trees in the field, the researchers found that the most vigporous plants were also those with the lowest levels of endotoxins. This was completely unexpected, and was probably due to the promoter used, which proves the importance of conducting field trials in this type of study. </p> Thu, 18 Jun 2015 14:16:53 +0200 Perspective No. 32. Investments in "smallholder" family farming. Towards a New Deal <p> This new issue of <em>Perspective</em> shows that integrated policies are required to foster family farmers' investment in their farms. The prime objective should be to reduce the burden on families of expenses and cut the time spent on certain domestic tasks, so as to free up their capacity to take initiatives. </p> Tue, 16 Jun 2015 15:58:24 +0200 R. Lancelot: "It is very difficult to link the emergence of diseases with climate change" <p> VIDEO. We tend to think that climate change and emerging diseases, whether they affect man or animals, are closely linked. However, the link is generally neither direct nor obvious. Some détails from an epidemiologist, Renaud Lancelot, who looked into the question at the global conference on climate-smart agriculture held in Montpellier in March. </p> Tue, 16 Jun 2015 14:35:32 +0200 Fruits, Vol. 70, No. 3 <p> A new issue of the journal <em>Fruits,</em> published by EDP Sciences and CIRAD. </p> Mon, 15 Jun 2015 15:37:30 +0200
