Andriatsitohaina, Muthoni R; Andrade, Robert, 2015, "Crop improvement, adoption and impact of improved bean varieties in Sub Saharan Africa", https://doi.org/10.7910/DVN/MOCXUN, Harvard Dataverse, V1, UNF:6:FwcNlj0hzJ0F3YlKgRIoPw== [fileUNF]
The crop improvement research effort of the Consultative Group on International Agricultural Research (CGIAR) centers and their national agricultural research systems (NARS) partners has had a large impact on world food production. Although bean impact has been documented in a number of past studies, the last comprehensive study of the internationa... |
Winowiecki, Leigh; Morrison, Scholastica; Weullow, Elvis; Sila, Andrew; Vågen, Tor Gunnar, 2015, "Near-infrared spectra for the AfSIS Sentinel Sites in Tanzania", https://doi.org/10.7910/DVN/YY9EKI, Harvard Dataverse, V1, UNF:6:TrbTfcBNfGOIHav5BiBn2g== [fileUNF]
The Africa Soil Information Service (AfSIS), was a project led by the Tropical Soil Biology and Fertility Institute (TSBF) of the International Center for Tropical Agriculture (CIAT), based in Nairobi, in collaboration with several partners including the World Agroforestry Centre (ICRAF). The AfSIS projectf aimed to narrow sub-Saharan Africa’s (SSA... |
Winowiecki, Leigh; Vågen, Tor Gunnar; Lyamchai, Charles; Sayula, George; Msoka, Elizabeth, 2015, "Landscape-scale variability of soil health indicators: Effects of cultivation on soil organic carbon in the Usambara Mountains of Tanzania", https://doi.org/10.7910/DVN/1YZAQZ, Harvard Dataverse, V3, UNF:6:7+CwQmpMAYoJf0ZNPJkuEg== [fileUNF]
During the Phase I of the CCAFS project we conducted a systematic land and soil health assessment in Lushoto District in November 2012. These data were used to inform climate-smart agricultural interventions for the IFAD project as well as to parameterize DSSAT crop models for maize and beans. The land and soil health assessment that was carried ou... |
Winowiecki, Leigh, 2015, "Soil and land health survey to characterize two-100 km2 sites using the Land Degradation Surveillance Framework (LDSF) within Babati district, Tanzania", https://doi.org/10.7910/DVN/CQLR9B, Harvard Dataverse, V1, UNF:6:0noGosp33jtQmw/n4CVeeg== [fileUNF]
This was Task 1.2. “Soil survey to characterize two sentinel sites” as part of Work Package 1 “Identification of the key biophysical production constraints to crops and livestock at farm and landscape levels” The aim of this task was to conduct an assessment of soil and land health in the Babati district in Tanzania covering the action villages of... |

Khoury, Colin K; Bjorkman, Anne D; Dempewolf, Hannes; Ramirez Villegas, Julian; Guarino, Luigi; Jarvis, Andy; Rieseberg, Loren H; Struik, Paul C, 2015, "Replication Data for: Increasing homogeneity in global food supplies and the implications for food security", https://doi.org/10.7910/DVN/HYOWIC, Harvard Dataverse, V1
The narrowing of diversity in crop species contributing to the world’s food supplies has been considered a potential threat to food security. However, changes in this diversity have not been quantified globally. We assess trends over the past 50 y in the richness, abundance, and composition of crop species in national food supplies worldwide. Over... |

Khoury, Colin K; Castañeda Álvarez, Nora P; Achicanoy, Harold A; Sosa, Chrystian C; Bernau, Vivian; Kassa, Mulualem T; Norton, Sally L; Van Der Maesen, Jos G; Upadhyaya, Hari D; Ramirez Villegas, Julian; Jarvis, Andy; Struik, Paul C, 2015, "Replication Data for: Crop wild relatives of pigeonpea [Cajanus cajan (L.) Millsp.]: Distributions, ex situ conservation status, and potential genetic resources for abiotic stress tolerance", https://doi.org/10.7910/DVN/GU5AJW, Harvard Dataverse, V1
Pigeonpea [Cajanus cajan (L.) Millsp.] is a versatile, stress-tolerant, and nutritious grain legume, possessing traits of value for enhancing the sustainability of dry sub-tropical and tropical agricultural systems. The use of crop wild relatives (CWR) in pigeonpea breeding has been successful in providing important resistance, quality, and breedin... |

Khoury, Colin K; Heider, Bettina; Castañeda Álvarez, Nora P; Achicanoy, Harold A; Sosa, Chrystian C; Miller, Richard E; Scotland, Robert W; Wood, John R; Rossel, Genoveva; Eserman, Lauren A; Jarret, Robert L; Yencho, Craig; Bernau, Vivian; Juarez, Henry; Sotelo, Steven; De Haan, Stef; Struik, Paul C, 2015, "Replication Data for: Distributions, ex situ conservation priorities, and genetic resource potential of crop wild relatives of sweetpotato [Ipomoea batatas (L.) Lam., I. series Batatas]", https://doi.org/10.7910/DVN/FLXJKU, Harvard Dataverse, V1
Crop wild relatives of sweetpotato [Ipomoea batatas (L.) Lam., I. series Batatas] have the potential to contribute to breeding objectives for this important root crop. Uncertainty in regard to species boundaries and their phylogenetic relationships, the limited availability of germplasm with which to perform crosses, and the difficulty of introgres... |
