Navarro Racines, Carlos E.; Vallejo Arango, Eliana; Ramirez Villegas, Julian, 2017, "500m gridded historical and future climate surfaces for Risaralda, Colombia", https://doi.org/10.7910/DVN/GIQMCI, Harvard Dataverse, V1
The gridded yearly climate data (5-year moving averages) were developed from weather station observations (from IDEAM and Cenicafe) for the period 1980 to 2010, at 500 m spatial resolution, for monthly precipitation, monthly minimum temperature and maximum temperature, following the method of Hijmans et al. (2005). In areas with low station density... |

Vallejo Arango, Eliana; Navarro Racines, Carlos E.; Ramirez Villegas, Julian; Aguilar Ariza, Andres; Delerce, Sylvain Jean, 2017, "500m gridded surfaces for changes in climate suitability for coffee production in Risaralda, Colombia", https://doi.org/10.7910/DVN/FEEHQX, Harvard Dataverse, V1
We used 500m gridded historical and future climate surfaces for Risaralda, Colombia and coffee presences and absences to train species distribution models (suitability). Five methods were used: Generalized Boosting Model (GBM) (Friedman, 2001), Random Forest (RF) (Breiman, 2001), Maxent (Phillips et al., 2006), Generalized Linear Model (GLM) and Ge... |
Labarta, Ricardo; Orrego, Mayra; Marin, Diego; García, María Alejandra; Twyman, Jennifer; Andrade, Robert; Yanez, Fernando; Mendoza, Luis, 2017, "Adoption of improved modern rice varieties and management practices in Ecuador", https://doi.org/10.7910/DVN/DX3F4T, Harvard Dataverse, V1
This dataset provides a description of rice growers collected in Ecuador between October 2014 and March 2015. The survey was implemented using a structured questionnaire administered among 1,028 households in the main rice production areas of Ecuador. Information collected was provided by household heads (. male or female) and included household an... |

Llanos Herrera, Lizeth; Navarro Racines, Carlos E.; Valencia, Jefferson; Monserrate, Fredy; Quintero, Marcela, 2017, "30 Arc-Second Historical and Future Scenario Climate Surfaces for Western Honduras", https://doi.org/10.7910/DVN/YR7QYP, Harvard Dataverse, V1
In order to characterize the historical climate for the Western Honduras region, it was developed monthly surfaces by years through spatial interpolation and available records of weather stations. The interpolated surfaces were generated at 1-km of spatial resolution (30 arc-seconds) for monthly precipitation (1981-2015), and minimum and maximum te... |
Le Thi, Dung Phuong; Labarta, Ricardo; Becerra, Luis Augusto; Rivera, Tatiana, 2017, "Vietnam household survey data for cassava varietal adoption study", https://doi.org/10.7910/DVN/4HJJXZ, Harvard Dataverse, V2, UNF:6:UehwmQaZK7eULI7vopmq6w== [fileUNF]
In 2015, CIAT and Vietnamese partners started a study on “Documenting the adoption of improved cassava varieties and assessing impacts on farm productivity and farm income of cassava genetic improvement in Vietnam”. This is the first such study in Vietnam and in the region using DNA fingerprinting to identify the cassava varieties planted by farmer... |
Ng’ang’a, Stanley Karanja; Mwungu, Chris M; Mwongera, Caroline; Kinyua, Ivy; Notenbaert, An; Girvetz, Evan, 2017, "Household Survey Data on Cost Benefit Analysis of Climate-Smart Soil Practices in Western Kenya", https://doi.org/10.7910/DVN/K6JQXC, Harvard Dataverse, V1, UNF:6:PCvs0HFQzjPTMPypL7JQvQ== [fileUNF]
This household survey was conducted among 88 respondents by CIAT in three counties of western Kenya (Bungoma, Kakamega, and Siaya) in 2016. The main aim of the project was to conduct a cost benefit analysis of eight climate-smart soil (CSS) practices, as a step toward understanding whether they were beneficial or not both from a private and social... |

Wilkus, Erin Lynn; Francesconi, Gian Nicola, 2017, "Value chain development to reach the nutritional needs of the urban poor: The role of brokers and SMEs for the commercialization of common beans in East Africa", https://doi.org/10.7910/DVN/N5UAVU, Harvard Dataverse, V1, UNF:6:NbIDQCDcO39dYOmMIztUow== [fileUNF]
This study addresses the need to empirically determine the effect of brokers on the performance of SMEs in the common bean value chains of Uganda and Kenya. Contrary to the conventional portrayal of brokers as scam artists, this analysis determined that broker use benefited SMEs by increasing profit margins of bean traders, wholesalers and retailer... |
