Quantifying soil carbon stocks and humification through spectroscopic methods: A scoping assessment in EMBU-Kenya
(ELSEVIER, 2019)A soil carbon assessment was performed comparing agricultural cropping systems with natural vegetation along a sampling transect spanning different agro-ecologies on the eastern foot slopes of Mount Kenya in Embu county, ... -
¿Qué aporta el conocimiento local para re-direccionar la investigación sobre el efecto de las raíces en reducción de erosión, secuestro de carbono y redistribución de agua en el suelo? : estudio de caso
(2014)Incluir la lógica de los productores en la investigación y transferencia de conocimientos es crucial para la adopción de buenas prácticas de manejo del agroecosistema. Para conocer la percepción de los productores sobre ... -
Radiation Interception, Conversion and Partitioning Efficiency in Potato Landraces: How Far Are We from the Optimum?
(MDPI, Basel (Switzerland), 2020-06)Crop efficiencies associated with intercepted radiation, conversion into biomass and allocation to edible organs are essential for yield improvement strategies that would enhance geneticproperties to maximize carbon gain ... -
Rank-based data synthesis of common bean on-farm trials across four Central American countries
(Crop Breeding & Genetics, 2022)Location-specific information is required to support decision making in crop variety management, especially under increasingly challenging climate conditions. Data synthesis can aggregate data from individual trials to ... -
Region-specific emission factors for Brazil increase the estimate of nitrous oxide emissions from nitrogen fertiliser application by 21%
(Elsevier, Ámsterdam, Países Bajos, 2020)The use of synthetic nitrogen fertilisers is one of the most important land management practices proposed to improve crop and pasture productivity. The use of such fertilisers in excess can lead to greenhouse gas (GHG) ... -
Rehabilitation and renovation of cocoa (Theobroma cacao L.) agroforestry systems. A review
(INRAE, París (France) ; Springer-Verlag France (Switzerland), 2021-10)Cocoa farmers must decide on whether to rehabilitate (Rh) or to renovate (Re) a cocoa orchard when its productivity declines due to ageing, disease outbreaks or other causes. Deciding on Rh/Re is often a complex, expensive ... -
Relevance of local knowledge in decision-making and rural innovation: A methodological proposal for leveraging participation of Colombian cocoa producers
(Elsevier, 2020)The local knowledge is constituted in the basis for decision-making and is an important part of the livelihood of rural families. Knowledge of cocoa crop management practices takes an essential role in the producers’ ... -
Retos y oportunidades para hacer la restauración activa de paisajes bancable

Risk analysis and cacao pod survivorship curves to improve yield forecasting methods
(Frontiers, 2024-03-22)Cocoa attainable yields are affected by a complex of pests and diseases in a particular agro-environment. Estimation of yield loss is critical for agronomic and economic decision-making at the farm level. For over 15 months, ... -
Sea Level Rise and Implications for Low Lying Islands, Coasts and Communities

Searching for manatees in the dark waters of a transboundary river between Mexico and Belize: a predictive distribution model
(Springer, Nueva York (Estados Unidos), 2020-11-05)Antillean manatees in the Hondo River have been recorded from aerial and aquatic surveys, and interviews. However, these studies have been conducted only in the lower riverbed, leaving a gap of information about their ... -
Secondary Tropical Dry Forests Are Important to Cattle Ranchers in Northwestern Costa Rica
(2020-07)In the dry regions of Central America, forests in cattle ranches are used as a refuge for cattle during the dry season, and there is no much information about this practice. To determine the frequency of this practice ... -
Selecting a core set of nuclear SNP markers for molecular characterization of Arabica coffee (Coffea arabica L.) genetic resources
(Springer, Nueva York (Estados Unidos), 2021)Coffee is one of the most economically important agricultural commodities in the world. Labeling accuracy and conservation efficiency are essential for coffee germplasm management and for the exchange and utilization in ... -
Shade and Agronomic Intensification in Coffee Agroforestry Systems: Trade-Off or Synergy?
(2021)Despite many years of research, there is still a lack of consensus as to the nature of the relationship between shade trees and agronomic intensification in coffee agroforestry systems. While some studies find unshaded ... -
Shade canopy density variables in cocoa and coffee agroforestry systems
(Springer Nature, 2023-12-18)An estimated 3.4 million hectares of cocoa and 9.7 million hectares of coffee are cultivated, globally, under shade trees, i.e. in agroforestry systems. Shade canopies are characterized in terms of tree density (N, trees ... -
Shade tree Chloroleucon eurycyclum promotes coffee leaf rust by reducing uredospore wash-off by rain
(Elsevier, Ámsterdam (Países Bajos), 2020)addition, may interact with environment. To better understand shade trees effects on coffee leaf rust (CLR), we studied three disease stages separately: sporulation, uredospore wash-off by rain, and uredospore deposition ... -
Shade tree identity rather than diversity influences soil macrofauna in cacao-based agroforestry systems
(Elsevier, Ámsterdam (Netherlands), 2021-09)Humanity is facing a rapid decline in global biodiversity, caused mainly by tropical deforestation through industrial and smallholder agriculture. However, smallholder agriculture landscapes host areas containing home ... -
Shade tree traits and microclimate modifications: Implications for pathogen management in biodiverse coffee agroforests
(Wiley Biotropica, New Jersey (Estados Unidos), 2021-04)Diversified coffee agroforests modify microclimate conditions in comparison with monocultures, impacting the success of significant plant pathogens, such as Hemileia vastatrix, which causes coffee leaf rust (CLR). However, ... -
ShadeMotion: tree shade patterns in coffee and cocoa agroforestry systems
(Springer, 2022-10-25)Shade trees in coffee and cocoa agroforestry systems provide valuable livelihoods and other ecosystem services. Unfortunately, most shade canopies are sub-optimally designed and managed and the reasons behind this ...
