International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/82362
Abstract
Three hundred small farmers from 42 villages of 5 Malawian regions were interviewed in order to gather information on the most common bean cropping systems, socioeconomic structure, farmers'organizations and income-generating activities, and extension service. Common beans are the 2nd most important crop after maize, providing a cheap…

https://hdl.handle.net/10568/120179
Abstract
In silico chromosome painting is a technique by which contributions of distinct genetic groups are represented along chromosomes of hybrid individuals. This type of analysis is used to study the mechanisms by which these individuals were formed. Such techniques are well adapted to identify genetic groups contributing to these individuals as well as hybridization events. It can also be used to follow…

Who defines fine chocolate? The construction of global cocoa quality standards from Latin America
https://hdl.handle.net/10568/120304
Abstract
The cocoa industry lacks globally harmonized quality standards. This article looks at how cocoa quality has been understood in the absence of industry-wide standards, the current interest in designing harmonized standards, the major debates about their content, and the implications their adoption could have across the cocoa value chain. It highlights the questions and dilemmas that emerge when…

A shift from cattle to camel and goat farming can sustain milk production with lower inputs and emissions in north sub-Saharan Africa’s drylands
https://hdl.handle.net/10568/120305
Abstract
Climate change is increasingly putting milk production from cattle-based dairy systems in north sub-Saharan Africa (NSSA) under stress, threatening livelihoods and food security. Here we combine livestock heat stress frequency, dry matter feed production and water accessibility data to understand where environmental changes in NSSA’s drylands are…

The cocoa yield gap in Ghana: A quantification and an analysis of factors that could narrow the gap
https://hdl.handle.net/10568/120413
Abstract
CONTEXT
Global cocoa production is largely concentrated in West Africa where over 70% of cocoa is produced. Here, cocoa farming is largely a rain-fed, low-input system with low average yields, which are expected to decline with climate change. With increasing demand, there is a need to evaluate opportunities to increase production whilst avoiding deforestation and expansion to croplands.…

Abstract
This study assessed the precipitation recycling and moisture sources in the Colombian Pacific region between 1980–2017, based on the monitoring of moisture in the atmosphere through the
EulerianWater Accounting Model-2 layer (WAM2 layer) and the delimitation of the area contributing to terrestrial and oceanic moisture in the region is performed using the “…

Gender inequalities in the Colombian cattle sector: an econometric analysis
https://hdl.handle.net/10568/120444
Abstract
Differences in access to productive resources, education, and credit can affect the productive capacity of cattle producers, especially women. This document analyses gender inequalities in the Colombian cattle sector using census information on the cattle activity, disaggregated at the territorial level. The econometric analysis evidences a negative relationship between the participation of women producers and…

https://hdl.handle.net/10568/55128
Abstract
In the Cerrados, a large savanna region in Brazil, the effects of different land use on aggregation in Oxisols were studied, using laser diffraction grain-size analyses. The topsoil of plowed systems had significantly fewer macroaggregates (194-2000 micro m) and a significantly larger fraction of…

Abstract
Several initiatives by the Government of Uganda, Research Institutes and CGIAR centers have promoted the use of tissue
culture (TC) banana technology as an effective means of providing clean planting material to reduce the spread of Banana
Xanthomonas wilt (BXW) but its uptake is still low. We examine factors that constrain…

Ecosystem service valuation along landscape transformation in Central Ethiopia
https://hdl.handle.net/10568/120618
Abstract
Land degradation and discontinuation of ecosystem services (ES) are a common phe nomenon that causes socio-economic and environmental problems in Ethiopia. However, a dearth of information is known about how ES are changing from the past to the future with regard to land use land cover (LULC) changes. This study aimed at estimating the values of ES based on the past and future LULC changes in central Ethiopia.…

Abstract
This study aimed at modeling scenarios of future land use and land cover (LULC) change and estimating ecosystem service (ES) values for the year 2051 compared to 2021 in Central Ethiopia. The future LULC changes for the year 2051 were simulated for four scenarios, namely Business-as-Usual (BAU), Rapid Agricultural Expansion (RAE), Ecosystems Protection and Agricultural Development (EPAD) and Landscape…

Abstract
We report the complete genome sequence of a field isolate of a novel bipartite secovirid infecting cassava in Colombia, provisionally named "cassava torrado-like virus" (CsTLV). The genome sequence was obtained using Oxford Nanopore Technology, and the 5’ ends were confirmed by RACE. The RNA1 is 7252 nucleotides (nt) long, encoding a polyprotein of 2336 amino acids (aa) containing the typical “…

Abstract
Cassava frogskin disease (CFSD) is a graft-transmissible disease of cassava reported for the first time in the 1970s, in Colombia. The disease is characterized by the formation of longitudinal lip-like fissures on the peel of the cassava storage roots and a progressive reduction in fresh weight and starch content. Since its first report, different pathogens have been identified in CFSD-affected plants and…
