Bean Program: The VEF(IBN)-EP-IBYAN scheme
https://hdl.handle.net/10568/77379
Abstract
To assure proper evaluation of all materials to be distributed internationally, the CIAT Bean Program designed a sequential process of germplasm evaluation and distribution known as the VEF-EP-IBYAN scheme. VEF (for the Spanish acronym of Bean Team Nursery) was an observational nursery; EP (Spanish acronym for Preliminary Trial) a regional yield trial and IBYAN the international yield trial. The scheme worked as follows:

Replication Data for: Phytoplasma infection of a tropical root crop triggers bottom-up cascades by favoring generalist over specialist herbivores
https://hdl.handle.net/10568/83459
Abstract
We tested the hypothesis that a Candidatus Phytoplasma causing cassava witches’ broom (CWB) on cassava (Manihot esculenta Grantz) is altering species composition of invasive herbivores and their associated parasitic hymenopterans. We conducted observational studies in cassava fields in eastern Cambodia to assess the effect of CWB infection on…

Intra-household and farm production decision making survey in rural Tanzania and Uganda
https://hdl.handle.net/10568/79409
Abstract
This intra-household survey was conducted by CCAFS in Northern Uganda and Southern Tanzania in 2014 and 2015 respectively. The main aim of the project is to increase farm production and farming system resilience of small scale farmers in Uganda and Tanzania while mitigating climate change through wide-scale adoption of climate-smart agriculture (CSA) technologies. Household identification variables…

Replication Data for:Biological nitrification inhibition by Brachiaria grasses mitigates soil nitrous oxide emissions from bovine urine patches
https://hdl.handle.net/10568/80921
Abstract
High nitrogen (N) concentration in bovine urine, which generally exceeds plant N uptake rates, results in the formation of hotspots of N loss when bovine urine is deposited on grazed pasture soils. High spatial variability in the distribution of urine patches in grazed pastures poses a major challenge to mitigate N losses. Some exudates from the…

CCAFS-CMIP5 Delta Method Downscaling for monthly averages and bioclimatic indices of four RCPs

Abstract
We developed a global dataset of downscaled future projections developed by applying a statistical method for climate model downscaling and bias correction. To develop the dataset, we applied the delta method, which comprises the sum of interpolated anomalies of each GCM to the WorldClim 1-km spatial resolution dataset. The GCMs were the 35 Coupled Model Intercomparison Project Phase 5 (CMIP5)…

Abstract
Germplasm of priority was established in CIAT-Quilichao for seed increase and for observations on the most important plant descriptors (plant form, growth habit, flowering time, perennially, etc.). Germplasm adaptation to the Quilichao environment was assessed in terms of: yield potential on a very acid, infertile Ultisol, including regrowth after cutting and performance during the two rather short but severe dry…

Abstract
Data were collected by a simulation model to estimate yield changes due to climate change in El Salvador, Guatemala, Honduras and Nicaragua. We analysed the simulated yield changes to spatially classify high-impact spots of climate change across the four countries. We identified hot spots, adaptation spots and pressure spots…
