Loaiza, Sandra; Da Silva, Mayesse; Chirinda, Ngonidzashe; Martínez Barón, Deissy, 2018, "Evaluation of the mitigation potential of the adaptation strategies implemented in the Climate – Smart Villages (CSV)", https://doi.org/10.7910/DVN/JJ6VZ6, Harvard Dataverse, V2
These data are from a study aimed at establishing current and potential vulnerability to soil water erosion across hilly landscapes in Popayán - Colombia and the department of Matagalpa – Nicaragua. Annual soil loss was determined through the use of the Universal Soil Loss Equation (USLE), which is constituted by five factors: Soil erodibility fact... |

Siles, Pablo; Valbuena, Diego; Tellez, Orlando; Bonilla, Glenda; Morales, Teresa; Van der Hoek, Rein; Castro, Aracely; Pulleman, Mirjam, 2018, "Replication Data for: Tree biodiversity and carbon stocks of different agroforestry systems in Nicaragua", https://doi.org/10.7910/DVN/DCGHWT, Harvard Dataverse, V1, UNF:6:DV60ukSZZMuIy5MwHywAgw== [fileUNF]
This study was aimed at quantifying the potential short-term impact of agroforestry-based systems on tree diversity and above and belowground carbon stocks in two representative SDTF sites in northern Nicaragua. Five land-use types were compared on 10 different farms across the two sites: Traditional slash–and-burn cropping systems (TCS), tradition... |

The new Latin America Greenhouse Gas Mitigation Network (LAMNET) is a regional subsidiary of The Climate Food and Farming Research Network (CLIFF), an international research network that helps to build the capacity of young researchers working on climate change mitigation in smallholder farming. The objective of the network is to enhance regional c... |
Delerce, Sylvain Jean, 2018, "Polygon map of soil units with functional properties for Mexico (1:250000)", https://doi.org/10.7910/DVN/QNMIZR, Harvard Dataverse, V1, UNF:6:yhuQWBl1nrw2t+JG2ZlDkQ== [fileUNF]
This 1:250000 soil map of Mexico is the result of a combination of three INEGI open-access datasets: The Series II soil units’ vectorial map is a nationwide polygon map delineating the soil groups at scale 1:250 000. It uses the World Reference Base for Soil Resources (WRB) to classify soils, and holds 63794 polygons. The Series I soil profiles dat... |

Ibrahim Wanyama; Mariana C. Rufino; David Pelster; George Wanyama; Clement Atzberger; Piet van Asten; Louis V. Verchot; Klaus Butterbach-Bahl, 2018, "Land use, land use history and soil type affect greenhouse gas fluxes from intact soil cores sampled across agricultural landscapes of the East African highlands", https://doi.org/10.7910/DVN/GSRD3R, Harvard Dataverse, V1, UNF:6:SvviQVzRDP7PqD9yeOmj2w== [fileUNF]
Data on greenhouse gas (GHG) fluxes from smallholder based systems in East Africa is limited. Estimation of GHG fluxes in smallholder farming systems is further constrained by the diversity of drivers of GHG fluxes such as land use, soil types, management intensities, climatic variables, and this renders field GHG fluxes measurements costly in term... |

The CLEANED (Comprehensive Livestock Environmental Assessment for Improved Nutrition, a Secured Environment and Sustainable Development along Livestock and Fish Value Chains) Excel tool is a rapid ex-ante environmental impact assessment tool that allows users to explore multiple impacts of developing livestock value chains. It models the impact of... |
Zomer, Robert J.; Bossio, Deborah A.; Sommer, Rolf; Verchot, Louis, 2017, "Replication Data for: Global Sequestration Potential of Increased Organic Carbon in Cropland Soils", https://doi.org/10.7910/DVN/HYFICT, Harvard Dataverse, V1
These datasets were developed as part of an analysis of the carbon sequestration potential of increasing soil organic carbon on croplands in the top 30cm of soil. The analysis estimates the carbon sequestration in tons per hectare after 20 years under improved management, with both a “medium” and a “high” scenario on the model presented in Sommer a... |
