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... |

Shikuku, Kelvin Mashisia; Winowiecki, Leigh; Twyman, Jennifer; Eitzinger, Anton; Perez, Juan G; Mwongera, Caroline; Läderach, Peter, 2017, "Replication Data for: Smallholder farmers’ attitudes and determinants of adaptation to climate risks in East Africa", https://doi.org/10.7910/DVN/VJWHT9, Harvard Dataverse, V1
The objective of organizing this dataset was to measure farmers’ attitudes and assess determinants of adaptation to climate risks in East Africa. This dataset comprises information about farmers’ adaptation strategies to climate risks in four CCAFS sites in east Africa, namely Nyando, Kenya; Hoima, Uganda; Lushoto, Tanzania; and Borana, Ethiopia. D... |

Kihara, Job; Sileshi, Gudeta W.; Nziguheba, Generose; Kinyua, Michael; Zingore, Shamie; Sommer, Rolf, 2017, "Replication Data for: Application of secondary nutrients and micronutrients increases crop yields in sub-Saharan Africa", https://doi.org/10.7910/DVN/8AJQJJ, Harvard Dataverse, V1
Secondary and micronutrients are important in enhancing crop productivity; yet, they are hardly studied in sub-Sahara Africa. In this region, the main focus has been on macronutrients but there is emerging though scattered evidence of crop productivity limitations by the secondary and micronutrients. Elsewhere, widespread deficiencies of these nutr... |
Laderach, Peter; Winowiecki, Leigh; Eitzinger, Anton; Twyman, Jennifer; Shikuku, Kelvin M., 2014, "Playing Out Transformative Adaptation in CCAFS Benchmark Sites in East Africa: "When, Where, How and With Whom?"", https://doi.org/10.7910/DVN/24451, Harvard Dataverse, V5
As part of this CCAFS project we collected various types of data in order to better understand vulnerabilities of smallholder farmers in East Africa to climate change. We collected and integrated interdisciplinary datasets in order to assess the biophysical, agronomic, social and economic realities at the sites. The study was carried out in four CC... |

Byrnes, Ryan C.; Núñez, Jonathan; Arenas, Laura; Rao, Idupulapati M; Trujillo, Catalina; Alvarez, Carolina; Arango, Jacobo; Rasche, Frank; Chirinda, Ngonidzashe, 2017, "Replication Data for:Biological nitrification inhibition by Brachiaria grasses mitigates soil nitrous oxide emissions from bovine urine patches", https://doi.org/10.7910/DVN/FVX1VR, Harvard Dataverse, V1, UNF:6:O7ueLsm0HN70OrfSHYgJJw== [fileUNF]
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 ro... |

International Center for Tropical Agriculture, 2017, "Database on GHG experiments conducted under the LivestockPlus project", https://doi.org/10.7910/DVN/IVYMGI, Harvard Dataverse, V1, UNF:6:hGHPoiSz9x1xHnooNF+ZeQ== [fileUNF]
The database contains data collected from experiments conducted different regions of Colombia (Meta, Atlántico, Casanare and Valle del Cauca). Specifically the data is on GHG emissions from urine and manure patches in grazed pastures and carbon stocks in representative pastures. In addition, there is data on enteric methane production. The collecte... |

Birnholz, Celine; Sommer, Rolf; Notenbaert, An; Paul, Birthe, 2017, "The Kalkulator: a minimum data tool for rapid ex-ante impact assessment of productivity, nitrogen balance, soil balance, and GHG emissions – Version 1.0.1", https://doi.org/10.7910/DVN/PT98JZ, Harvard Dataverse, V1
The Kalkulator is a rapid ex-ante impact assessment tool with minimum data requirements that allows users to benchmark and explore multiple environmental impacts of interventions (e.g. productivity-enhancing agricultural practices, soil protection measures) on a farm using four indicators: greenhouse gas emissions, soil nitrogen balance, soil erosi... |

This database contains data obtained from measurements of nitrous oxide from urine patches on improved and degraded pastures in five countries in LAC (Colombia, Argentina, Nicaragua, Brazil and Trinidad & Tobago). Specifically, the data is on N2O fluxes, soil proprieties, nitrogen content in urine and soil nitrogen. In addition, we include data on... |

The summary includes data collected from surveys conducted made in the Climate Smart Villages (CSVs) of Cauca-Colombia and El Tuma La Dalia-Nicaragua. The data includes parameters related to soils, cropping systems, land use, land-use changes and livestock in these both villages. The data was them used in Carbon calculator (Cool Farm Tool) to quant... |
