Ovalle, Oriana; Läderach, Peter; Bunn, Christian; Obersteiner, Michael; Schroth, Götz, 2015, "Replication Data for: Projected shifts in Coffea arabica suitability among major global producing regions due to climate change", https://doi.org/10.7910/DVN/29634, Harvard Dataverse, V3
The dataset has 2194 coffee location points. Most of the data came from projects developed by the International Center for Tropical Agriculture (CIAT) in collaboration with other research centers and producer cooperatives. We modeled the global distribution of Arabica coffee under changes in climatic suitability by 2050s as projected by 21 global c... |
Hyman, Glenn; Fujisaka, Sam; Jones, Peter G; Wood, Stanley; Vicente, M. Carmen de; Dixon, John, 2015, "Replication Data for: Strategic approaches to targeting technology generation: Assessing the coincidence of poverty and drought-prone crop production", https://doi.org/10.7910/DVN/ACXHHB, Harvard Dataverse, V1, UNF:6:bhVICfZ84NP2cwJJ+cHiOg== [fileUNF]
The world’s poorest and most vulnerable farmers on the whole have not benefited from international agricultural research and development. Past efforts have tried to increase the production of countries in more favourable environments; farmers with relatively higher potential for improvement benefited most from these advances. Current and future cro... |

Gourdji, Sharon; Läderach, Peter; Martinez Valle, Armando; Zelaya Martinez, Carlos; Lobell, David B, 2015, "Replication Data for: Historical climate trends, deforestation, and maize and bean yields in Nicaragua", https://doi.org/10.7910/DVN/29206, Harvard Dataverse, V1, UNF:6:px5p6Y7tf6Rn+QVXHjMDdQ== [fileUNF]
Nicaragua has already experienced substantial climate change, in part due to a loss of one half of its forest cover in the last half-century. In this study, we assess the extent to which historical climate trends have contributed to stagnating yields for maize (Zea mays) and bean (Phaseolus vulgaris), the two main staple crops in the country. We fi... |

Herrera Campo, Beatriz Vanessa; Hyman, Glenn; Bellotti, Anthony, 2014, "Replication data for: Threats to cassava production: known and potential geographic distribution of four key biotic constraints", https://doi.org/10.7910/DVN/27490, Harvard Dataverse, V4
The potential distribution map of the Cassava Greenmite is the result of a weighted overlay combination of several ecological models and a set of environmental variables. Models used were Environmental Distance, Genetic Alrgorithm for Rule-set Production and Support vector Machines . Environmental variables include: Bioclim dataset, number of conse... |

Parsa, Soroush; Kondo, Takumasa; Winotai , Amporn, 2014, "Replication data for: The Cassava Mealybug (Phenacoccus manihoti) in Asia: First Records, Potential Distribution, and an Identification Key", https://doi.org/10.7910/DVN/27604, Harvard Dataverse, V2
Potential distribution of Cassava Mealybug (Phenacoccus maniholi). Pest risk map, based on model predicting climatic suitability for Phenococcus maniholi. Climatic suitability is estimated by the Eco climatic index (EI), values greater than 20 indicate high risk of infestations. |

Jones, Peter G; Thornton, Philip K, 2014, "Failed Season drought probability", https://doi.org/10.7910/DVN/27504, Harvard Dataverse, V2
This map estimates the drought probability based on the water balance and simulated daily rainfall. A failed season occurs when there is insufficient water to meet crop requirements. The failed season algorithm (FSA) has been used in a number of application including Hyman et al. 2008. |

Castañeda Álvarez, Nora P; Khoury, Colin K; Sosa, Chrystian C; Achicanoy, Harold A; Bernau, Vivian, 2014, "Germplasm Collection Gaps and Species Richness of Wild Relatives of Important Root, Tuber and Banana Crops.", https://doi.org/10.7910/DVN/27487, Harvard Dataverse, V4
The wild relatives of crops represent a major source of valuable traits for crop improvement. These resources are threatened by habitat destruction, land use changes, and other factors, requiring their urgent collection and long-term availability for research and breeding from ex situ collections. We propose a method to identify gaps in ex situ col... |
