Abstract We examine factors affecting the adoption of improved cassava varieties 217 households in Cauca Department southwest Colombia. Using DNA fingerprinting through Single Nucleotide Polymorphisms ( SNP s), we identified different cultivars farmers fields. also used this information to remove possible bias model that could have resulted from a misclassification IV s). As result, found substantially overestimate their use s and there are important differences determinants between farmer...

Abstract Using a double-hurdle approach, we assess factors associated with the extent of participation in rice market data for small-scale farmers drawn from nationally representative dataset. The results suggest that larger endowments and assets, animal farming commercialization, alternative off-farm income make less likely to participate. Conversely, having access credit, farm sizes, being part farmers’ association all increase likelihood participation. Farms better technological resources...

<p>Multivariate and ordered Probit models were used to study the determinants of adoption extent agronomic practices among cacao farmers in Nariño, Colombia, with data from 353 mountain region. Results suggest that farmers’ decisions are made on a joint basis, further validating use multivariate approach. The presence illegal crops creates strong disincentives affect possibility more significant technological improvements. Adequate access agricultural technical assistance strongly...

Abstract Bolivia has disseminated several improved technologies in the rice sector, but average productivity country is far below trend Latin America recent years. Although economic literature highlighted role of agricultural technology adoption increasing productivity, gaps remain understanding how growers are deciding to adopt and benefit from available technologies. Most previous studies have evaluated uptake individual without paying attention complementarities that alternative may offer...

Rice research and technology development in Latin America has increased yields offered the opportunity for several countries to contribute global food security by becoming net exporters of this cereal. In spite broad availability rice technologies region, remain substantially low like Bolivia. This study examines how Bolivian growers make simultaneous decisions about adopting improved varieties chemical fertilizers joint decision influences productivity crop. By exploiting a nationally...

We study the effect of temperature on students' performance and how changes in incentives to alter this impact context high-school exit exams Colombia. show that increases have a negative exam scores, particularly among urban students. Conversely, rural students exhibit slightly positive effects. Leveraging time-use data, we find evidence individuals areas responding by reallocating time towards off-farm activities, which are human capital intensive. Additionally, announcement national...

Introduction. Long-term genetic improvement efforts in Latin America aimed to ameliorate peach-palm fruit farmers’ technical capacities and livelihoods have proven be ineffective. Although experts agree this is partly the result of large uncertainty regarding consumer preferences, such research remains as virtually nonexistent. Objective. To identify chemical morphologic attributes that are attractive for final consumers how these related perceptions quality, through statistical econometric...

Potato is a traditional and economically important crop for farmers in the high mountains of Nariño (Colombia). However, its productivity growth weakening, injuring farmers’ livelihoods. We hypothesize that an in-depth study farm typologies their relationship with productive efficiency could prove helpful delivering recommendations sector improvement. With representative sample 1,018 farmers, this research used cluster methods to identify types farming then stochastic frontier model build...

Pitfall trapping remains one of the most frequently used methods to assess ground-active arthropods’ diversity and density. Yet, its main drawbacks, possibility that repeated collecting may affect study objects’ population, has not been formally tested. We studied effect a yearlong epigeal pitfall exercise with 22 fortnightly capture events in four differently disturbed areas at Colombian Pacific coast. A transect 100 m length ten equidistant traps was established each area, were operated...

The purpose of this paper is to analyze the state art, concerning role information and communication technologies (ICT) in both, ebusiness innovation strategies small medium size enterprises. literature review conducted covered main theoretical models developed by previous researches, emphasizing approached based on resource-based view firm, as most promising alternative understanding influence ICT resources management business processes.
