Abstract

This article presents the conceptual framework for assessing farm sustainability using the IDEA4 method. IDEA4 combines a dual assessment approach based on sustainable agriculture objectives and the properties of sustainable farming systems. It is rooted in the domains of strong sustainability, strong agroecology and the multifunctionality of agriculture. It takes into account the overall issues of sustainable agriculture. This conceptual framework has been used to construct 53 indicators for analysing farm sustainability using two complementary approaches. The first assesses sustainability by organising these 53 indicators according to the 3 normative dimensions of sustainable development (agroecological, socio-territorial, economic), structured into 13 components. This assessment relies on a scoring system based on 100 sustainability units for each of the 3 dimensions, which cannot offset each other. The second approach is used to assess sustainability by organising the same 53 indicators according to the 5 properties of sustainable agricultural systems (ability to produce and reproduce goods and services, autonomy, robustness, territorial embeddedness, and overall responsibility), which are arranged in a tree structure with 15 branches. Indicators are aggregated in a qualitative and hierarchical manner using the DEXi tool. The exploratory potential of the concept of the properties of sustainable systems encourages a transdisciplinary approach for assessing farms. IDEA4’s theoretical framework is now complemented by three information technology (IT) tools, which means that the method can be used to a much greater extent to support the agroecological transition.

Abstract

Neocortical neurons can increasingly be divided into well-defined classes, but their activity patterns during quantified behavior remain to be fully determined. Here, we obtained membrane potential recordings from various classes of excitatory and inhibitory neurons located across different cortical depths in the primary whisker somatosensory barrel cortex of awake head-restrained mice during quiet wakefulness, free whisking and active touch. Excitatory neurons, especially those located superficially, were hyperpolarized with low action potential firing rates relative to inhibitory neurons. Parvalbumin-expressing inhibitory neurons on average fired at the highest rates, responding strongly and rapidly to whisker touch. Vasoactive intestinal peptide-expressing inhibitory neurons were excited during whisking, but responded to active touch only after a delay. Somatostatin-expressing inhibitory neurons had the smallest membrane potential fluctuations and exhibited hyperpolarising responses at whisking onset for superficial, but not deep, neurons. Interestingly, rapid repetitive whisker touch evoked excitatory responses in somatostatin-expressing inhibitory neurons, but not when the intercontact interval was long. Our analyses suggest that distinct genetically-defined classes of neurons at different subpial depths have differential activity patterns depending upon behavioral state providing a basis for constraining future computational models of neocortical function.

Abstract

The higher intensity of labor observed in many agroecological farming systems has been little studied by the scientific community, especially in terms of work organization. Narrative interview research concerning 34 farmers in six French farm machinery cooperatives, on the basis of the farming styles framework, allows us to highlight a specific style of farm work conducive to the agroecological transition. Farmers members of these cooperatives have developed a long-standing reliance on peer-to-peer cooperation, gradually shaping a labor-intensive and collective style of farm work to make their conventional farming systems viable. They have then remobilized with relative ease the structuring basis of their initial organization of work, i.e., labor intensity and peer-to-peer cooperation, to develop agroecological practices.

Abstract

We characterize the complexity of liveness verification for parameterized systems consisting of a leader process and arbitrarily many anonymous and identical contributor processes. Processes communicate through a shared, bounded-value register. While each operation on the register is atomic, there is no synchronization primitive to execute a sequence of operations atomically. We analyze the case in which processes are modeled by finite-state machines or pushdown machines and the property is given by a B\"uchi automaton over the alphabet of read and write actions of the leader. We show that the problem is decidable, and has a surprisingly low complexity: it is NP-complete when all processes are finite-state machines, and is PSPACE-hard and in NEXPTIME when they are pushdown machines. This complexity is lower than for the non-parameterized case: liveness verification of finitely many finite-state machines is PSPACE-complete, and undecidable for two pushdown machines. For finite-state machines, our proofs characterize infinite behaviors using existential abstraction and semilinear constraints. For pushdown machines, we show how contributor computations of high stack height can be simulated by computations of many contributors, each with low stack height. Together, our results characterize the complexity of verification for parameterized systems under the assumptions of anonymity and asynchrony., Comment: 27 pages, 1 figure

Abstract

Abstract Background As an increasing number of deaths occur in the intensive care unit (ICU), studies have sought to describe, understand, and improve end-of-life care in this setting. Most of these studies are centered on the patient’s and/or the relatives’ experience. Our study aimed to develop an instrument designed to assess the experience of physicians and nurses of patients who died in the ICU, using a mixed methodology and validated in a prospective multicenter study. Methods Physicians and nurses of patients who died in 41 ICUs completed the job strain and the CAESAR questionnaire within 24 h after the death. The psychometric validation was conducted using two datasets: a learning and a reliability cohort. Results Among the 475 patients included in the main cohort, 398 nurse and 417 physician scores were analyzed. The global score was high for both nurses [62/75 (59; 66)] and physicians [64/75 (61; 68)]. Factors associated with higher CAESAR-Nurse scores were absence of conflict with physicians, pain control handled with physicians, death disclosed to the family at the bedside, and invasive care not performed. As assessed by the job strain instrument, low decision control was associated with lower CAESAR score (61 (58; 65) versus 63 (60; 67), p = 0.002). Factors associated with higher CAESAR-Physician scores were room dedicated to family information, information delivered together by nurse and physician, families systematically informed of the EOL decision, involvement of the nurse during implementation of the EOL decision, and open visitation. They were also higher when a decision to withdraw or withhold treatment was made, no cardiopulmonary resuscitation was performed, and the death was disclosed to the family at the bedside. Conclusion We described and validated a new instrument for assessing the experience of physicians and nurses involved in EOL in the ICU. This study shows important areas for improving practices.

Abstract

Abstract Background Lanreotide autogel is a somatostatin analog (SSA) approved for the treatment of acromegaly in 73 countries worldwide; however, it is not yet approved in China. The aim of this study was to evaluate the efficacy and safety of lanreotide autogel compared with lanreotide 40 mg prolonged release (PR) in Chinese patients with active acromegaly. Methods LANTERN was a phase 3, randomized, open-label, non-inferiority study. Patients with active acromegaly who had undergone surgery ≥3 months prior, or were unlikely or unable to undergo surgery, were treated with lanreotide autogel 60/90/120 mg (monthly deep subcutaneous injection) or lanreotide 40 mg PR (intramuscular injection every 7, 10, or 14 days) for 32 weeks. Primary endpoint was mean change-from-baseline in age-adjusted insulin-like growth factor-1 (IGF-1) standard deviation scores (SDS) at the end-of-study. Secondary endpoints included: growth hormone (GH) levels ≤2.5 μg/L or ≤ 1.0 μg/L, ≥20% reduction in tumor volume (TV) and safety. Results In total, 128 patients were randomized and received study treatment. Lanreotide autogel was non-inferior to lanreotide 40 mg PR: treatment difference (95% CI) for IGF-1 SDS between groups was − 0.32 (− 0.74, 0.11; per protocol population) and − 0.27 (− 0.63, 0.09; intention-to-treat [ITT] population), respectively. Reductions in IGF-1 (− 6.453 vs − 7.003) and GH levels (− 9.548 μg/L vs − 13.182 μg/L), and the proportion of patients with ≥1 acromegaly symptom (− 20.3% vs − 32.5%) were observed from baseline to end-of-study in lanreotide autogel and lanreotide 40 mg PR groups, respectively. In the lanreotide autogel group, 45.5% (25/55) patients achieved ≥20% reduction in TV compared with 50.9% (25/53) in lanreotide 40 mg PR group (ITT). Safety profiles were similar in both treatment groups. Conclusions Lanreotide autogel was non-inferior to lanreotide 40 mg PR in Chinese patients with active acromegaly after 32 weeks of treatment. Trial registration Retrospectively registered on ClinicalTrials.gov: NCT02493517 (9 July 2015); prospectively registered on chinadrugtrials.org.cn: CTR20140698 (24 October 2014).

Abstract

The postpartum period is crucial in dairy cows and is marked by major physiological and metabolic changes that affect milk production, immune response and fertility. Nutrition remains the most important lever for limiting the negative energy balance and its consequences on general health status in highly selected dairy cows. In order to analyze the effect of a commercial micronutrient on intrinsic parameters, performances and the epigenome of dairy cows, 2 groups of 12 Holstein cows were used: 1 fed a standard diet (mainly composed of corn silage, soybean meal and non-mineral supplement) and the other 1 fed the same diet supplemented with the commercial micronutrient (µ-nutrient supplementation) for 4 weeks before calving and 8 weeks thereafter. Milk production and composition, BW, body condition score (BCS), DM intake (DMI) and health (calving score, metritis and mastitis) were recorded over the study period. Milk samples were collected on D15 and D60 post-calving for analyses of casein, Na+ and K+ contents and metalloprotease activity. Milk leukocytes and milk mammary epithelial cells (mMECs) were purified and counted. The viability of mMECs was assessed, together with their activity, through an analysis of gene expression. At the same time points, peripheral blood mononuclear cells (PBMCs) were purified and counted. Using genomic DNA extracted from PBMCs, mMECs and milk leukocytes, we assessed global DNA methylation (Me-CCGG) to evaluate the epigenetic imprinting associated with the µ-nutrient-supplemented diet. The µ-nutrient supplementation increased BCS and BW without modifying DMI or milk yield and composition. It also improved calving condition, reducing the time interval between calving and first service. Each easily collectable cell type displayed a specific pattern of Me-CCGG with only subtle changes associated with lactation stages in PBMCs. In conclusion, the response to the µ-nutrient supplementation improved the body condition without alteration of global epigenetic status in dairy cows.

Abstract

Although evidence continues to indicate an urgent need to transition food systems away from industrialized monocultures and toward agroecological production, there is little sign of significant policy commitment toward food system transformation in global North geographies. The authors, a consortium of researchers studying the land-food nexus in global North geographies, argue that a key lock-in explaining the lack of reform arises from how most food system interventions work through dominant logics of property to achieve their goals of agroecological production. Doing so fails to recognize how land tenure systems, codified by law and performed by society, construct agricultural land use outcomes. In this perspective, the authors argue that achieving food system “resilience” requires urgent attention to the underlying property norms that drive land access regimes, especially where norms of property appear hegemonic. This paper first reviews research from political ecology, critical property law, and human geography to show how entrenched property relations in the global North frustrate the advancement of alternative models like food sovereignty and agroecology, and work to mediate acceptable forms of “sustainable agriculture.” Drawing on emerging cases of land tenure reform from the authors' collective experience working in Scotland, France, Australia, Canada, and Japan, we next observe how contesting dominant logics of property creates space to forge deep and equitable food system transformation. Equally, these cases demonstrate how powerful actors in the food system attempt to leverage legal and cultural norms of property to legitimize their control over the resources that drive agricultural production. Our formulation suggests that visions for food system “resilience” must embrace the reform of property relations as much as it does diversified farming practices. This work calls for a joint cultural and legal reimagination of our relation to land in places where property functions as an epistemic and apex entitlement.

Abstract

Abstract Background Clostridium difficile infection (CDI) is associated with a substantial Quality of life impact on patients that has not been so far measured with a generic validated instrument. Methods A prospective study was performed in 7 French acute-care settings in patients presenting with a bacteriologically-confirmed CDI. The EQ-5D-3 L was filled in by patients at 7 ± 2 days after CDI diagnosis to describe their state of health at that date as well as their state of health immediately before the CDI episode (baseline). Individual utility decrement was obtained by subtracting the corresponding utilities. The Quality Adjusted Life Year (QALY) loss was calculated by multiplying the days spent from baseline to the date of the interview, by the decrement of utility. A multivariate analysis of variance of the utility decrement according to CDI and patients characteristics was performed. Results Eighty patients were enrolled (mean age: 69.4 years, 55% females). The utility scores dropped from a mean 0.542 (SD: 0.391) at baseline to 0.050 (SD: 0.404) during the CDI episode with a mean adjusted utility decrement of 0.492 (SD: 0.398) point. This decrement increased significantly with CDI severity (Zar score ≥ 3) (p = 0.001), in patients with a positive baseline utility (p = 0.032), in women as compared to men (p = 0.041) and in patients aged more than 65 years (p = 0.041). No association with the Charlson index was found. The associated QALY loss not integrating the excess mortality was 0.028 (SD: 0.053). Conclusions The impact on quality of life of CDI episodes is major and translates in a substantial QALY loss despite their short duration.

Abstract

Oil palm fertilizer requirements are based on leaflet mineral concentrations. Four oil palm progenies representing a wide genetic diversity of Elaeis guineensis species and with contrasting K and Mg leaflet concentrations were tested in Indonesia and Nigeria, environments which differ predominantly in climate. During 5 years, we compared oil palm progenies’ leaflet mineral concentrations between both countries under abundant fertilizer applications to investigate the extent to which they depend on the environment. In the two studied environments, leaflet concentrations significantly differed between progenies for K, Mg and Ca, but the country effect was not found significant (p = 0.352) for any leaflet mineral’s concentration. In both countries, progenies ranked similarly in their mineral categories (lowest and highest cation concentrations within the 4 progenies population), indicating that leaflet mineral concentrations in the tested oil palm progenies are mainly determined by their genetic background. For each progeny, with abundant fertilization, K, Mg and Ca proportions to total leaf cation charge (TLCC) were similar, irrespective of the environments in which the palms were cultivated. We have strong indications that foliar concentrations of K, Mg and Ca are determined by genetic factors which dominate the environmental effect. However, it remains uncertain whether differences in oil palm foliar concentrations between different oil palm progenies imply that they require specific fertilizer amounts to attain an optimal production.

Abstract

We compared four oil palm (Elaeis guineensis Jacq.) progenies’ morphological growth characteristics to reveal genotypic differences in plant growth and assess their adaptability in Nigeria’s environment in response to different levels of potassium chloride (KCl) and kieserite fertilizer applications. The studied progenies (C1, C2 and C3 of Deli × La Mé origin and C4 of Deli × Yangambi origin) represent a wide genetic diversity of oil palm and have shown among a population of 116 different progenies, a contrasting K and Mg leaflet concentrations that covered the extreme ranges of leaflet concentrations in these minerals. The trial consisted of a completely randomized split-plot factorial design with six replicates, where progenies, considered as sub-factor were treated with combinations of 3 levels of potassium chloride (0, 1.5, 3.0 kg of KCl palm−1 year−1) and kieserite (0, 0.75, 1.5 kg of MgSO4 palm−1 year−1) fertilizers (main factor), respectively. Growth characteristics differed significantly among progenies, but not in all studied years. In all progenies, KCl treatments significantly increased the average annual collar girth increment and projected canopy area. Adding 3.0 kg palm−1 year−1 of KCl significantly increased the total leaf area of progeny C4. Kieserite applications did not have an effect on progenies’ growth characteristics whereas potassium showed to be the main mineral needed for oil palm growth. It was shown that with equal amounts of fertilizers applied, progeny C3 had better morphological traits than the other progenies, suggesting that the effective nutrient requirements should be assessed for each individual progeny and that fertilization should be adapted accordingly.

Abstract

Abstract Background Spermatozoa have a remarkable epigenome in line with their degree of specialization, their unique nature and different requirements for successful fertilization. Accordingly, perturbations in the establishment of DNA methylation patterns during male germ cell differentiation have been associated with infertility in several species. While bull semen is widely used in artificial insemination, the literature describing DNA methylation in bull spermatozoa is still scarce. The purpose of this study was therefore to characterize the bull sperm methylome relative to both bovine somatic cells and the sperm of other mammals through a multiscale analysis. Results The quantification of DNA methylation at CCGG sites using luminometric methylation assay (LUMA) highlighted the undermethylation of bull sperm compared to the sperm of rams, stallions, mice, goats and men. Total blood cells displayed a similarly high level of methylation in bulls and rams, suggesting that undermethylation of the bovine genome was specific to sperm. Annotation of CCGG sites in different species revealed no striking bias in the distribution of genome features targeted by LUMA that could explain undermethylation of bull sperm. To map DNA methylation at a genome-wide scale, bull sperm was compared with bovine liver, fibroblasts and monocytes using reduced representation bisulfite sequencing (RRBS) and immunoprecipitation of methylated DNA followed by microarray hybridization (MeDIP-chip). These two methods exhibited differences in terms of genome coverage, and consistently, two independent sets of sequences differentially methylated in sperm and somatic cells were identified for RRBS and MeDIP-chip. Remarkably, in the two sets most of the differentially methylated sequences were hypomethylated in sperm. In agreement with previous studies in other species, the sequences that were specifically hypomethylated in bull sperm targeted processes relevant to the germline differentiation program (piRNA metabolism, meiosis, spermatogenesis) and sperm functions (cell adhesion, fertilization), as well as satellites and rDNA repeats. Conclusions These results highlight the undermethylation of bull spermatozoa when compared with both bovine somatic cells and the sperm of other mammals, and raise questions regarding the dynamics of DNA methylation in bovine male germline. Whether sperm undermethylation has potential interactions with structural variation in the cattle genome may deserve further attention.

Abstract

Abstract Background There is great potential for the genetic improvement of oil palm yield. Traditional progeny tests allow accurate selection but limit the number of individuals evaluated. Genomic selection (GS) could overcome this constraint. We estimated the accuracy of GS prediction of seven oil yield components using A × B hybrid progeny tests with almost 500 crosses for training and 200 crosses for independent validation. Genotyping-by-sequencing (GBS) yielded +5000 single nucleotide polymorphisms (SNPs) on the parents of the crosses. The genomic best linear unbiased prediction method gave genomic predictions using the SNPs of the training and validation sets and the phenotypes of the training crosses. The practical impact was illustrated by quantifying the additional bunch production of the crosses selected in the validation experiment if genomic preselection had been applied in the parental populations before progeny tests. Results We found that prediction accuracies for cross values plateaued at 500 to 2000 SNPs, with high (0.73) or low (0.28) values depending on traits. Similar results were obtained when parental breeding values were predicted. GS was able to capture genetic differences within parental families, requiring at least 2000 SNPs with less than 5% missing data, imputed using pedigrees. Genomic preselection could have increased the selected hybrids bunch production by more than 10%. Conclusions Finally, preselection for yield components using GBS is the first possible application of GS in oil palm. This will increase selection intensity, thus improving the performance of commercial hybrids. Further research is required to increase the benefits from GS, which should revolutionize oil palm breeding.

22. Why and how to conduct a Scoping Review of literature in the Humanities and Social Sciences? Application to free labour in agriculture

Author

Barisaux, Marie, Gasselin, Pierre, Laurens, Lucette, and Ollivier, Guillaume

Abstract

Literature reviews stand as familiar and relevant tools within the research community, as mean to produce a state of knowledge to justify the relevance of a research question. Among the many methods that can be used, systematic approaches are developing in the Humanities and Social Sciences (HSS). These review methodologies employ rigorous techniques in the identification, retrieval, and analysis of data. The overarching objective is to uphold transparency and replicability in research endeavours, elevating the overall quality and credibility of scholarly work in these disciplines. By presenting the two main systematic approaches to literature reviews – Systematic Literature Reviews (SLRs) and Scoping Reviews (SRs) –, we intend to clarify their respective objectives and methods, so that interested researchers can make an informed choice between them. We thus show that an SR aims to characterise the extent (or scope) of research on a subject or field, whereas an SLR aims to answer a specific question with a view to guiding practices. We also show the interest of these approaches for the HSS. We use a case study – free or unpaid labour in agriculture – to illustrate the different stages of a systematic approach to a literature review. We begin by justifying the choice of an SR over an SLR, and then test the former’s methodology through its various stages. The aim is to provide guidelines for researchers wishing to undertake this type of work. We reflect on this methodology, illustrating its advantages and disadvantages in the light of our experience. We show that systematic approaches to literature reviews are non-linear and time-consuming processes which require constant back-and-forth and reflection between the various stages. Nevertheless, their contributions in helping us understand complex subjects, develop expertise and achieve transparency show that they are suitable approaches for the HSS.

29. New Challenges in Agricultural Advisory Services from a Research Perspective: A Literature Review, Synthesis and Research Agenda

Author

Faure, Guy, Desjeux, Yann, and Gasselin, Pierre

Abstract

Purpose: Agricultural advisory services are perceived by many actors involved in rural development as a key driver behind innovation processes in agriculture. However, changes in national and global contexts cause dramatic changes in the orientation of advisory services, their organisation and their methods of intervention. This article aims to analyse the major research topics related to agricultural advice. Design/methodology/approach: The study is based on an extensive review of literature produced over a ten-year period that is accessible through the CAB, ECONLIT and Web of Science citation indexes. Using keywords related to extension and advisory services, we selected published articles according to the relevance of the results provided in relation to advisory services and the quality of the discussion on past or current controversies. Findings: The results show that the ongoing scientific debates are shaped by the diversity of disciplines, methods, topics and schools of thought. The scientific community largely has focussed on five main themes: (1) the institutional environment of agricultural advisory services; (2) the structures necessary for the operation of an advisory system; (3) the actors providing advisory services and the skills deployed in advisory activities; (4) the approaches, methods, tools and content of advisory activities; and (5) the assessment and impacts of advisory systems. Practical implications: This literature review is useful for researchers and practitioners to better understand research results in the field of advisory services. It paves the way for future research. Originality/Value: Although many articles have been written in recent decades on agricultural advisory services, few studies provide an overview of the contributions of, and debates in, the international scientific community. (Contains 4 tables.)

33. Sélection du palmier à huile pour une huile de palme durable et responsabilité sociale

Abstract

As an actor of a supply chain, seed producers must take into account the impact of their work on sustainability. This is particularly true when one works on palm oil, a highly sensitive crop which is questioned on its social and environmental impact. Breeders act directly on yield thus increasing profitability, while for the same production, decreasing land-use pressure. In addition, breeders act on duration of the plantations - which is critical for a perennial crop - making strategic choices selecting for lasting resistances to diseases. They can seek rustic selections, which help the work of small holders and enable them to a better social insertion in the supply chain. In the long trend, the promotion of sustainable palm oil is an excellent opportunity for palm oil seed distributors. Corporate and Social Responsibility of PalmElit, company recently created, is presented. It defines its aspirations, its values, its direct and indirect responsibilities and finally proposes an operational code of conduct.

Abstract

For a tropical plant, the oil palm commodity chain has the peculiarity of possessing a major seed production sector for reasons that are primarily genetic. This seed sector has numerous original aspects. Breeders are also propagators and usually also distribute their seeds. Oil palm seeds are semi-recalcitrant: they display pseudo-dormancy. Achieving seed germination is difficult and requires lengthy treatments and special installations. This restriction greatly influences seed distribution and the role of the different stakeholders in the commodity chain. It was only once it had been discovered how the “sh” gene functioned, which controls shell thickness, and when it became necessary to produce “tenera” seeds derived from exclusively “dura x pisifera” crosses, that a true seed market developed. In addition it is difficult to organize seed distribution to smallholders. This is partly due to difficulties that the profession, or a State-run organization, has in controlling middlemen networks, and partly to the absence of any protective systems (UPOV, plant breeder certificate, etc.) that generally oblige breeders to preserve and propagate parents in their own installations. In fact there are major inequalities in the access to seeds between agroindustry and smallholders. Another peculiarity of the oil palm seed market is the virtually total absence of guarantees for buyers: the quality of the research conducted by breeders, the seed production strategies necessary for transferring genetic progress, and the technical quality of production. The only guarantee today comes from the relations of confidence established year after year between breeders/distributors and growers. In this fields, research can lead to some proposals: molecular biology offers some interesting prospects for certifying seed quality and social science develop effective communication methods.

Abstract

Genetic improvement of the oil palm may have a role to play in the sustainability of this crop. Given the criticism aimed at this commodity chain, notably due to the extension of oil palm plantations to the detriment of forests, providing very high-yielding planting material might be a solution, particularly as world demand is continually increasing. This crop is mostly managed by agroindustrialists, but the smallholder sector is developing. It happens that this sector is classed as a sustainable type of agriculture by numerous NGOs, which are also asking plant breeders to take the specificities of smallholdings into consideration. Oil palm genetic improvement takes numerous criteria into account, many of which fit in with sustainable agriculture. For example, this crop is subject to pressure from different pests and diseases. In each case, a genetic hence eco-friendly approach has been taken and, in particular, vascular wilttolerant planting material has been a successfully produced. Moreover, for the future of this crop, planting material needs to be developed that requires fewer inputs, and consideration has to be given to extending this crop in less favourable zones, by developing planting material that consumes less water. Lastly, it is important to disseminate genetically diversified planting material.

Abstract

Le palmier à huile (Elæis guineensis Jacq.) est originaire d’Afrique où il est encore exploité de façon traditionnelle. L’intensification de sa culture a commencé au début du xxe siècle, en Asie du Sud-Est. Ce n’est qu’entre les deux guerres mondiales que cette intensification s’est manifestée en Afrique. En Amérique latine, cette culture ne s’est développée que depuis la fin des années 60. En 2000, la production d’huile s’élève à 21,7 millions de tonnes. Par ailleurs, les extensions et renouvellements de plantations demeurent très vifs. Ainsi, les surfaces plantées sont de 6 562 000 hectares dans le monde en 2000 [1]. Dans ces conditions, le marché mondial des semences est estimé à plus de 150 millions de graines par an. Autant les agro-industriels se fournissent le plus souvent auprès des obtenteurs, autant les planteurs villageois, en particulier en Afrique, ne s’adressent pas systématiquement à eux, et sont confrontés à des désagréments ultérieurs, lors de la mise en récolte de leur plantation. Les semences commerciales de qualité prennent en compte des contraintes liées à la biologie florale de cette plante ainsi qu’aux caractéristiques morphologiques de la graine. Elles sont fabriquées en respectant un cahier des charges rigoureux permettant d’éviter aux exploitants de très mauvaises désillusions.

Abstract

La productivité du palmier à huile au cours du siècle passé a connu une croissance importante où l’amélioration génétique a pris une large part. Elle a connu un rythme de croissance assez comparable à celui obtenu pour des plantes annuelles de pays tempérés (blé, maïs, tournesol, etc.). Il est possible de dégager les étapes importantes qui ont marqué l’histoire de l’amélioration. Après une assez longue période de sélection massale, l’exploitation du gène « shell », dont l’hérédité a été découverte par Beirnaert en 1939, a apporté une amélioration de 30% [1]. Vers 1960, l’exploitation de l’hétérosis des croisements inter-origines apporte une nouvelle amélioration de 10% environ [2]. Enfin, deux cycles de sélection récurrente ont été achevés par différentes équipes et chacun a apporté 12 à 18% d’amélioration de la productivité. En 1991, la valeur moyenne des semences commerciales, plantées dans de bonnes conditions, était proche de 6,7 tonnes d’huile par hectare et par an [3]. Aujourd’hui, elle est de l’ordre de 7,2 t/ha/an [4]. Ces gains quantitatifs ont été accompagnés de progrès qualitatifs importants comme la diminution de la vitesse de croissance, l’augmentation du pourcentage d’huile dans les régimes ou l’acquisition d’une forte résistance à la fusariose en Afrique de l’Ouest [5]. La qualité du futur matériel végétal devrait être sensiblement améliorée par l’utilisation d’une base génétique élargie dans les programmes d’amélioration [6]. En effet, les stations de recherche disposent d’une bonne diversité génétique rassemblée lors de nombreuses prospections réalisées en Afrique (pour E. guineensis) et sur une espèce apparentée en Amérique latine (pour E. oleifera). Ces collections apportent de nouveaux caractères de qualité de l’huile, de résistance à la fusariose, qui sévit en Afrique, ou à la pourriture du cœur en Amérique latine. Le progrès génétique disponible en expérimentation doit être intégré dans les semences vulgarisées au plus vite et en quantité suffisante. Cependant, pour la reproduction du meilleur matériel, il existe des contraintes liées à la biologie des semences qui compliquent et ralentissent cette vulgarisation. En raison d’une dormance difficile à lever, les semences de palmier à huile sont distribuées sous forme de graines germées et leur distribution demande une organisation particulière.
