A functional analysis of inflorescence architecture in Musa L. (Musaceae)
https://hdl.handle.net/10568/155433
Abstract
Inflorescence architecture underpins sexual reproduction in wild Musa species and productivity in edible banana cultivars. In a functional analysis, we identified the apical inflorescence and lateral ‘cushion’ meristems and the change in flower type as the three primary components that generate inflorescence architecture. Five genotypes of two clone sets of edible plantains ( Musa AAB) were grown for four generations…

Modeling farmers’ preference and willingness to pay for improved climate services in Rwanda
https://hdl.handle.net/10568/121962
Abstract
This study aims to understand how Rwandan farmers value the improved characteristics of climate services introduced to them in a choice experiment setting. Data were collected from 1,525 household heads in November 2019. A random parameters logit model was used to analyze the data. Results suggest that Rwandan farmers value forecast accuracy, dissemination through a combination of extension agents…

First report of cassava witches’ broom disease and Ceratobasidium theobromae in the Americas
https://hdl.handle.net/10568/162790
Abstract
Cassava (Manihot esculenta) is a primary source of carbohydrates for millions of people in the tropics. In the Americas, cassava also holds deep cultural and economic significance for indigenous peoples (Parmar et al., 2017). However, the increased commercialisation and connectivity between cassava-producing regions has heightened the risks of the introduction of diseases that threaten this food…

Conservation status of three rare endemic Phaseolus bean (Leguminosae, Phaseoleae) species of Costa Rica
https://hdl.handle.net/10568/163019
Abstract
We aimed at an inventory of all populations of wild Phaseolus (bean) species in Costa Rica, in relation to future plant breeding. During the field work in 2003–2018, three new and rare bean species (i.e. P. albicarminus , P. angucianae and P. hygrophilus ) were found in different montane forest habitats which originally occupy a small acreage. Field observations, together with satellite…

Power & protein—closing the ‘justice gap’ for food system transformation
https://hdl.handle.net/10568/151954
Abstract
The protein shift, or transition, entails a reduction in the production and consumption of animal-source foods, and an increase in plant-based foods and alternative proteins, at a global level. The shift is primarily motivated by the need to minimise the impact of the food system on social-ecological systems. We argue that rather than focusing singularly on transitioning a ‘protein gap’ in diets, redressing the ‘…

Negative social tipping dynamics resulting from and reinforcing Earth system destabilization
https://hdl.handle.net/10568/155135
Abstract
In recent years, research on normatively positive social tipping dynamics in response to the climate crisis has produced invaluable insights. In contrast, relatively little attention has been given to the potentially negative social tipping processes that might unfold due to an increasingly destabilized Earth system and to how they might in turn reinforce social and ecological destabilization…

Culture of impact in agricultural research organisations: What for and how?
https://hdl.handle.net/10568/162493
Abstract
Research organisations experience increasing demands to analyse on the multidimensional societal impacts of their activities. This leads to more reflections about the integration of organisational strategies devoted to research evaluation and impact monitoring, in order to answer societal and funder's demands, improve research practices, and make research and innovations more transformative to society.…

Physicochemical characterization of special cassava starches and their application for bio-ethanol production through no-cook technology at very high gravity
https://hdl.handle.net/10568/152317
Abstract
Various cassava genotypes were developed with distinct starch characteristics, including amylose-free and small-granule mutations. Despite these unique traits, the ethanol production potential of these starches has not been explored. Cassava starch plays a crucial role in ethanol production, particularly in tropical countries like…

Cacao grafting increases crop yield without compromising biodiversity
https://hdl.handle.net/10568/170086
Abstract
Yields of tropical tree crops decline with time, often forcing smallholders to establish new deforestation‐derived plantations. Consequently, alternative strategies reconciling crop yield and biodiversity conservation are essential. Grafting is a common propagation method to boost yield in crops as cacao, but it alters tree structure potentially affecting associated insect diversity. We investigated how grafting affects…

Abstract
There is a general agreement among scholars that bundling Climate Information Services (CIS), Climate Smart Agriculture (CSA), and other agricultural products and services can positively impact agriculture. However, many questions still need to be answered regarding how the bundling can be achieved through scalable and farmer-centric CIS-CSA bundled business models. This study narrowed the…

Abstract
Abstract Tracking progress towards the Global Goal on Adaptation requires documentation of countries’ intentions, against which future progress can be measured. The extent to which existing national policy documents provide adequate baselines is unclear. We evaluated the adequacy of African Nationally Determined Contributions (NDCs) ( N = 53) and National Adaptation Plans (NAPs) ( N = 15) against three…
