Article
Full-text available
Crop adaptation to climate change requires accelerated crop variety introduction accompanied by recommendations to help farmers match the best variety with their field contexts. Existing approaches to generate these recommendations lack scalability and predictivity in marginal production environments. We tested if crowdsourced citizen science can a...

Full-text available
Tricot (triadic comparisons of technologies) is a citizen science approach for testing technology options in their use environments, which is being applied to on-farm testing of crop varieties. Over the last years, important progress has been made on the tricot methodology of which an overview is given. Trial dimensions depend on several factors bu...
Article
Full-text available
Crowdsourced citizen science is an emerging approach in plant sciences. The triadic comparison of technologies (tricot) approach has been successfully utilized by demand-led breeding programmes to identify varieties for dissemination suited to specific geographic and climatic regions. An important feature of this approach is the independent way in...
Article
Full-text available
Crop breeding must embrace the broad diversity of smallholder agricultural systems to ensure food security to the hundreds of millions of people living in challenging production environments. This need can be addressed by combining genomics, farmers’ knowledge, and environmental analysis into a data-driven decentralized approach (3D-breeding). We t...
Article
Full-text available
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 produce information that supports decision making in plant breeding programs, extension services, and of farmers. Data from on-farm...
Article
Full-text available
Climate change is altering suitable areas of crop species worldwide, with cascading effects on people reliant upon those crop species as food sources and for income generation. Macadamia is one of Malawi’s most important and profitable crop species; however, climate change threatens its production. Thus, this study’s objective is to quantitatively...
Preprint
Full-text available
Climate change is altering suitable areas of crop species worldwide, with cascading effects on people and animals reliant upon those crop species as food sources. Macadamia is one of Malawi's most important and profitable crop species. Here, we used an ensemble model approach to determine the current distribution of macadamia producing areas across...
Technical Report
Full-text available
Triadic comparison of technology options (tricot) is a research methodology that helps farmers to identify the most suitable technologies for the local conditions of their farm. Tricot (read: ‘try-cot’) engages farmers as ‘farmer researchers’ in the testing or validation of new crop varieties and other promising technologies. Tricot is supported by...

Data and R code used in the paper de Sousa, K., & Solberg, S. Ø. (2020). Conservation Gaps in Traditional Vegetables Native to Europe and Fennoscandia. Agriculture, 10(8), 340. https://doi.org/10.3390/agriculture10080340
Article
Full-text available
Vegetables are rich in vitamins and other micronutrients and are important crops for healthy diets and diversification of the food system, and many traditional (also termed underutilized or indigenous) species may play a role. The current study analyzed 35 vegetables with a European region of diversity with the effort to map the conservation status...

The chirps package provides functionalities for reproducible analysis in R (R Core Team, 2020) using the CHIRPS (Funk et al., 2015) data. CHIRPS is daily precipitation data set developed by the Climate Hazards Group (Funk et al., 2015) for high resolution precipitation gridded data. Spanning 50 • S to 50 • N (and all longitudes) and ranging from 19...

API client for 'ClimMob', an open source software for crowdsourcing citizen science in agriculture under the 'tricot' method <https://climmob.net/climmob3/>. Developed by van Etten et al. (2019) <doi:10.1017/S0014479716000739>, it turns the research paradigm on its head; instead of a few researchers designing complicated trials to compare several t...

Climate change threatens coffee production and the livelihoods of thousands of families in Mesoamerica that depend on it. Replacing coffee with cocoa and integrating trees in combined agroforestry systems to ameliorate abiotic stress are among the proposed alternatives to overcome this challenge. These two alternatives do not consider the vulnerabi...
Data
Harvard Dataverse <https://doi.org/10.7910/DVN/0O1GW1>. We performed an ensemble method for Species Distribution Modelling (SDM) using a subset of 17 SDM algorithms. The area cover the current Mesoamerica, comprised by Panama to central Mexico (coordinates-101 to-77 W, 7 to 22 N). All analyses were done in R (version 3.3.3) using a consensus method...
Technical Report
Full-text available
Under accelerated climatic and socioeconomic change, farmers need quick solutions, including access to a range of crop seeds. Seeds for Needs provides a simple, cost-efficient way for a diversity of farmers to (i) have access to a broad range of crop diversity (ii) characterize it using molecular, morphological and farmer evaluation data, (iii) eva...
Data
Harvard Dataverse <https://doi.org/10.7910/DVN/4ICF6W>. Farmers were invited to collaborate as citizen science volunteers in the crowdsourcing approach "tricot" (triadic comparison of technologies). We organized tricot trials, testing 10 common bean varieties (Phaseolus vulgaris) in Nicaragua during five growing seasons, 62 durum wheat (Triticum du...

La región de Centroamérica cubre una superficie de 524.000 km2, de los cuales 181.000 km2 (el 35%) corresponden a lo que se denomina “Corredor Seco Centroamericano”. En la región viven aproximadamente 26 millones de personas, más de la mitad de ellas en el área rural, que se caracteriza por un alto índice de pobreza y una agricultura de subsistenci...

Silvopastoral systems—the management of trees within pastures from natural regeneration or planting—are a strategy to promote sustainable livestock systems and ecosystems services. Timber is one of the products from these systems with potential to increase family revenues. The management of natural regeneration and population dynamics of trees is a...

Chapter
Full-text available
This is a Chapter from the handbook "Manejo de sementes para o cultivo de espécies florestais da Amazônia" (in Portuguese) which aims to provide technical information regarding the production, management and conservation of 50 focal tree species in Central Amazon. In this Chapter we present the potential uses of these 50 species.
Article
Full-text available
The importance of tropical timber is increasing worldwide. However, the timber supply of tropical forests has been greatly impacted by growing deforestation associated with complex and restrictive timber harvest laws. In Central America, as well as in other developing regions, reforestation programs have often fallen short of expectations. In these...
Conference Paper
Full-text available
Seed conditioning is a technique that can increase the vigor and speed of the germination process (Mendonça et al., 2005), which consists in pre-soaking the seeds in sufficient quantity to activate the metabolism, but insufficient to allow the protrusion of the primary root (Bradford, 1986). Activation of metabolism allows the recovery of damage ac...

For Bertholletia excelsa H.B.K. (Brazil nut) the optimal temperature for seed germination is not yet known. This species occurs in the Amazon region in terra firme forests. The objective of this work was to determine the optimum temperature for the evaluation of seed quality in the laboratory in order to provide subsidies for the elaboration of the...
