The Cost

Latex harvesting is the most costly activity in natural rubber production and the shortage of available skill and unstable latex harvester are the main factor affecting in Rubber cultivation and its lead to increase cost of production. Low frequency system (LFT) with the hormonal stimulation is a solution to solve this problem that minimize the cost of latex harvesting. Therefore, a study was conducted for nine years on production systems that minimize the cost of latex harvesting in southwestern Côte d'Ivoire with clones IRCA 130, GT 1 and PB 217 of Hevea brasiliensis. These production systems differ from each other by an increase in tapping frequency, in comparison with the standard tapping (d3) on the above clones in southwestern Côte d'Ivoire. The results indicated that production systems that minimize the cost of latex harvesting admittedly resulted in losses of rubber yield per hectare per year from 1 to 37%, but improved the yield per tree per tapping as well as the productivity of the tapper from 20 to 46%, in year. Moreover, these systems contributed to the improvement of the vegetative growth of trees and kept the rate of dry trees in low level (less than 7%). Furthermore, these systems also helped to reduce the cost of tapping labor from 1 to 50%, as well as operating costs from 2 to 47%, in comparison with European Scientific Journal October 2018 edition Vol.14, No.30 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431 191 the standard tapping (d3). Finally, in the context of a shortage of tapping labor, these systems help increase the farmer’s profit margin from 26% to 113%, as well as the tapper’s income from 26% to 89%. Therefore, it appears that the use of low frequency harvesting system with the appropriate stimulants appears as a solution to minimize latex harvesting cost and unavailability of harvesters in rubber cultivation.

Cassava Production

SUMMARYIn order to intensify cassava production in southern Côte d'Ivoire, multiple farmers’ field trials were carried out in two important cassava-producing areas (Dabou and Bingerville). The effectiveness of an Integrated Soil Fertility Management (ISFM) approach as intensification pathway was evaluated for poor sandy soils. Overall, ISFM-based systems outperformed the local cultivation system. The average cassava yield was 14.5 and 6.5 t ha−1 and 12.6 and 5.7 t ha−1 for the ISFM and traditional systems, in Dabou and Bingerville, respectively. The average profitability of ISFM systems was ca. 2500 Euro ha−1, whereby 66% was generated by cowpea intercrop, which yielded on average 3.1 t ha−1. Taking into account the limited farmer's resource endowment and poor soil fertility, ISFM is a crucial component for sustainable intensification of cassava production and poverty alleviate in southern Côte d'Ivoire.

The Cost

Abstract Background The NEVEREST-3 (South Africa) and MONOD-ANRS-12206 (Côte d’Ivoire, Burkina Faso) randomized trials found that switching to efavirenz (EFV) in human immunodeficiency virus–infected children >3 years old who were virologically suppressed by ritonavir-boosted lopinavir (LPV/r) was noninferior to continuing o LPV/r. We evaluated the cost-effectiveness of this strategy using the Cost-Effectiveness of Preventing AIDS Complications–Pediatric model. Methods We examined 3 strategies in South African children aged ≥3 years who were virologically suppressed by LPV/r: (1) continued LPV/r, even in case of virologic failure, without second-line regimens; continued on LPV/r with second-line option after observed virologic failure; and preemptive switch to EFV-based antiretroviral therapy (ART), with return to LPV/r after observed virologic failure. We derived data on 24-week suppression (<1000 copies/mL) after a switch to EFV (98.4%) and the subsequent risk of virologic failure (LPV/r, 0.23%/mo; EFV, 0.15%/mo) from NEVEREST-3 data; we obtained ART costs (LPV/r, $6–$20/mo; EFV, $3–$6/mo) from published sources. We projected discounted life expectancy (LE) and lifetime costs per person. A secondary analysis used data from MONOD-ANRS-12206 in Côte d’Ivoire. Results Continued LPV/r led to the shortest LE (18.2 years) and the highest per-person lifetime cost ($19 470). LPV/r with second-line option increased LE (19.9 years) and decreased per-person lifetime costs($16 070). Switching led to the longest LE (20.4 years) and the lowest per-person lifetime cost ($15 240); this strategy was cost saving under plausible variations in key parameters. Using MONOD-ANRS-12206 data in Côte d’Ivoire, the Switch strategy remained cost saving only compared with continued LPV/r, but the LPV/r with second-line option strategy was cost-effective compared with switching. Conclusion For children ≥3 years old and virologically suppressed by LPV/r-based ART, preemptive switching to EFV can improve long-term clinical outcomes and be cost saving.

L'importance de l'hévéa (caoutchouc), Hevea brasiliensis, en tant que culture de rente ne cesse d'augmenter justifiant de s'intéresser à de nouvelles techniques de clonage plus efficaces que le greffage (écussonnage) traditionnellement utilisé pour la production industrielle de matériel de plantation de qualité supérieure. Les bonnes performances sur le terrain (croissance rapide, haut rendement) des hévéas produits par embryogenèse somatique n'ont été constatées jusqu'à présent qu'à l'échelle expérimentale. La propagation de masse in vitro par embryogenèse somatique ou microbouturage de clones d'hévéas sur leurs propres racines reste pénalisée par un manque de réactivité de la plupart des génotypes sélectionnés et par des coûts de production prohibitifs. Face à cette situation, la propagation par bouturage de clones matures sélectionnés issus de micropropagation in vitro a été tentée par la SoGB en Côte d'Ivoire comme une alternative possible à l'utilisation exclusive des techniques in vitro. Les deux clones matures industriels, A (70 ans) et B (53 ans), ont d'abord été rajeunis in vitro par embryogenèse somatique puis micropropagés en plus grand nombre par microbouturage. Après acclimatation, les microboutures enracinées in vitro ont été rempotées dans des pots individuels pour être gérées de manière intensive comme pieds-mères destinés au bouturage. Après 3 semaines en conditions horticoles adéquates, les taux d'enracinement obtenus pour les boutures des clones A et B ont été respectivement de 74,6 % (1203/1613) et 76,5 % (198/259). Les racines adventices néoformées étaient généralement vigoureuses. A l'issue d'une phase d'acclimatation réussie, les boutures se sont développées de façon conforme pour atteindre 4 mois plus tard une hauteur de 25-30 cm suffisante pour être plantées au champ. En sus d'une plus grande vigueur et conformité sur le terrain, les clones issus de bouturage peuvent être produits plus rapidement, sur des surfaces plus réduites à moindre coût et dans des conditions de travail plus faciles par rapport aux plantes issus d'écussonnage. Des analyses en cours devraient permettre d'établir les avantages comparatifs des boutures par rapport aux plants écussonnés en ce qui concerne d'autres caractères à fort impact économique tels que le rendement de latex.
