Evidence of agroecology’s contribution to mitigation, adaptation, and resilience under climate variability and change in Latin America
https://hdl.handle.net/10568/132858
Abstract
Agroecology is highly promoted in research and development discourse as a holistic and effective response to climate change. The objective of this study is to contribute to the analysis of the existing evidence that agroecology enables climate change (CC) adaptation and mitigation in the agricultural systems of Latin America, a region known for pioneering…

The association between food environment, diet quality and malnutrition in low‐ and middle‐income adult populations across the rural—Urban gradient in Vietnam
https://hdl.handle.net/10568/132291
Abstract
Background: Economic reforms and trade liberalisation in Vaietnm have transformed the food environment, influencing dietary patterns and malnutrition status. The present study focuses on the relationship between food environments (proximity and density of food outlets) and malnutrition (underweight, overweight, obesity) through diet…

Large range sizes link fast life histories with high species richness across wet tropical tree floras
https://hdl.handle.net/10568/177265
Abstract
Understanding how the traits of lineages are related to diversification is key for elucidating the origin of variation in species richness. Here, we test whether traits are related to species richness among lineages of trees from all major biogeographical settings of the lowland wet tropics. We explore whether variation in mortality rate, breeding system and maximum diameter are related to…

Nutritive value of perennial pastures along an elevation gradient in tropical conditions
https://hdl.handle.net/10568/179472
Abstract
The nutritive value of forages is one of the main drivers of productivity for livestock. In many tropical regions, same grass species occur at different elevations, but few studies have evaluated nutritive value changes within elevation gradients. Methods The objective of this study was to analyze the changes in nutritive value of six grass genera across and within elevation gradients in Costa Rica. We…

https://hdl.handle.net/10568/110819
Abstract
Smallholder maize farmers in Africa experience pre- and post-harvest production stresses either individually or in combination at different stages of the crop cycle. The maize weevil is among the major post-harvest storage pests. A strategy to address this problem is to develop and…

Do farmers’ socioeconomic status determine the adoption of conservation agriculture? An empirical evidence from Eastern and Southern Regions of Cameroon
https://hdl.handle.net/10568/126468
Abstract
The African Union’s Agenda 2063 and the Malabo Declaration recognize agricultural development as one of the most effective means of combating extreme poverty. Conservation Agriculture Practices (CAP) have been asserted to have the potential to boost agricultural output, improve livelihood and contribute to the conservation of natural…

An optimized nucleic acid isolation protocol for virus diagnostics in cassava (Manihot esculenta Crantz.)
https://hdl.handle.net/10568/120937
Abstract
Our group works on the detection and characterization of cassava viruses, supporting projects that involve large scale pathogen surveillance activities and resistance screening assays in multiple and remote locations. In order to comply with these applications, nucleic acid isolation protocols need to be cost effective, adjusted for samples that will stand long distance transport and…

Understanding farmers’ acceptance of digital technologies: A meta-analytic structural equation modeling approach based on the technology acceptance model
https://hdl.handle.net/10568/181650
Abstract
Understanding how farmers accept and interact with digital technologies is crucial for transforming agriculture and improving smallholder livelihoods. Despite widespread use of the technology acceptance model (TAM) to understand farmers’ adoption of digital technologies, findings remain inconsistent. We applied a two-stage meta-analytic…

Genetic mapping and validation of QTL for whitefly resistance in cassava (Manihot esculenta Crantz)
https://hdl.handle.net/10568/175498
Abstract
QTL associated with whitefly resistance were identified in a cassava F2 population and KASP markers applicable in selection for the trait were validated. Whitefly species pose a major threat to cassava production in tropical regions causing direct plant damage and transmitting viruses that lead to devastating cassava diseases. Aleurotrachelus socialis whitefly is one of the pests that affect…

Feeding climate and biodiversity goals with novel plant-based meat and milk alternatives
https://hdl.handle.net/10568/131912
Abstract
Abstract Plant-based animal product alternatives are increasingly promoted to achieve more sustainable diets. Here, we use a global economic land use model to assess the food system-wide impacts of a global dietary shift towards these alternatives. We find a substantial reduction in the global environmental impacts by 2050 if globally 50% of the main animal products (pork, chicken, beef and milk) are…

Abstract
Background: Consumer preferences for boiled or fried pieces of roots, tubers and bananas (RTBs) foodstuffs are mainly related to their texture. Different raw and cooked RTBs were physiochemically characterised to determine the effect of biochemical components on their cooking properties.
Results: Firmness in boiled sweetpotato increases with sugar and amylose contents but no…
