La papa es uno de los principales cultivos para la seguridad alimentaria y económica de vastas poblaciones en el mundo y en especial en las zonas altoandinas. Su producción y almacenamiento se ve seriamente afectada por plagas de insectos, en especial por el gorgojo de los Andes y la polilla de la papa. Para su control, normalmente se usan insecticidas, lo que puede ser muy tóxico para la salud humana y ambiental. El CIP junto con sus aliados (instituciones nacionales, ONG, comunidades campesinas) han desarrollado y validado alternativas de manejo integrado de plagas (MIP), las cuales han demostrado ser altamente eficaces desde el punto de vista biológico, económico y ambiental. Estas innovaciones consisten en el uso de barreras plásticas para el control del gorgojo de los Andes, de atracticidas para reducir las infestaciones de polillas en campo y almacenamiento así como de talco con Bacillus thuringiensis subesp. kurstaki (Talco-Btk) para proteger los tubérculos durante el almacenamiento. Las innovaciones fueron validadas en gran escala y han beneficiado a cientos de pequeños agricultores en el Perú.

Is crop breeding the first step to fill the yield gap? Understanding the impact and constraints of developing new improved varieties.

Is crop breeding the first step to fill the yield gap? Understanding the impact and constraints of developing new improved varieties. | Articles Published by CIP Staff | Scoop.it
International Potato Center (CIP)'s insight:

Monneveux, P.; Ortiz, O.; Merah, O. 2013.Is crop breeding the first step to fill the yield gap? Understanding the impact and constraints of developing new improved varieties. Secheresse. 24(4):254-260.

One of the main challenges of the present century is to face the increasing food demand by enhancing farmers’ yield, but with less area and less water. The present paper analyzes how crop improvement and agronomic management have contributed to this objective, until now either by improving crop yield potential or by filling the gaps between yield potential and farmers’ yield. It reviews critically whether better varieties can replace or reduce the need of good agronomic practices in the future. It finally attempts to describe the role to be played by crop management technologies over the next decades to allow the genetic potential of new varieties to be expressed

Improved cryopreservation method for the long-term conservation of the world potato germplasm collection | Articles Published by CIP Staff | Scoop.it
International Potato Center (CIP)'s insight:

Panta, A.; Panis, B.; Ynouye, C.; Swennen, R.; Roca, W.; Tay, D.; Ellis, D.  2014. Improved cryopreservation method for the long-term conservation of the world potato germplasm collection. Plant Cell, Tissue and Organ Culture (PCTOC) [Open Access]

The effect of cold and sucrose pretreatment for increasing tolerance to cryopreservation was evaluated with eight diverse genotypes . In vitro plantlets were cultured at either 6 or 22 °C in media supplemented with either 0.07 or 0.3 M sucrose prior to droplet PVS2 cryopreservation. The sucrose pretreatment appeared to have no positive effect on post-cryo survival. The cold-hardening pretreatment increased significantly post-cryo recovery in drought and frost tolerant cultivars. When 755 accessions, representing 10 taxa, were cryopreserved after cold-hardening, 96 % responded with at least one shoot recovering and 63 % showed a high recovery rate (40–100 %). Therefore this method is recommended for the long term conservation of diverse accessions of potato germplasm.

Impact of Information and Communication Technology-Based Market Information Services on Smallholder Farm Input Use and Productivity: The Case of Kenya | Articles Published by CIP Staff | Scoop.it
International Potato Center (CIP)'s insight:

Ogutu, S.O.; Okello, J.J.; Otieno, D.J. 2014. Impact of information and communication technology-based market information services on smallholder farm input use and productivity: The case of Kenya. World Development. (UK).  64:311-321. http://dx.doi.org/10.1016/j.worlddev.2014.06.011.

Information asymmetry has traditionally constrained smallholder farmers’ access to markets, consequently limiting their adoption of modern technologies and farm productivity. Improved smallholder farmers’ access to markets via the recent Information and Communication Technology (ICT) platforms has the potential to reverse this scenario. This study uses Propensity Score Matching (PSM) technique to evaluate the impact of an ICT-based market information services (MIS) project on farm input use and productivity in Kenya. It finds a positive and significant impact of the intervention on the use of seeds, fertilizers, land, and labor productivity. However, a negative impact on labor usage is found.

 Considerable efforts are being directed at tackling the problem of cassava viruses in Africa. Yet these efforts are not fully coordinated, and the overall scale of mitigation programs is tiny compared with the scale of the threats to the world’s cassava crop. With this in mind, the Global Cassava Partnership for the 21st Century - GCP21, a recognized global organization within the cassava community, gathered representatives of 24 research and development (R&D) organizations and donor agencies at the Rockefeller Foundation Center, in Bellagio, Italy, on 5–10 May 2013. The workshop established a Global Alliance to Declare a War on Cassava Viruses in Africa, to develop a strategic action plan.
