Advances in improving tolerance to waterlogging in Brachiaria grasses
https://hdl.handle.net/10568/35013
Abstract
An inter-institutional and multi-disciplinary project to identify *Brachiaria* genotypes, which combine waterlogging tolerance with high forage yield and quality, for use in agricultural land in Latin America with poor drainage, is underway. The aim is to improve meat and milk production and mitigate the impacts of climate change in the humid areas of Latin America. Researchers at the International Center for Tropical…

Science-policy interfaces for sustainable climatesmart agriculture uptake: lessons learnt from national science-policy dialogue platforms in West Africa
https://hdl.handle.net/10568/103990
Abstract
Connecting science with policy has always been challenging for both scientists and policymakers. In Ghana, Mali and Senegal, multi-stakeholder national science-policy dialogue platforms on climate-smart agriculture (CSA) were setup to use scientific evidence to create awareness of climate change impacts on agriculture and advocate for the…

Dry forest based livelihoods in resettlement areas of Northwestern Ethiopia
https://hdl.handle.net/10568/16652
Abstract
While the importance of forests for livelihoods has long been well-recognized, empirical knowledge of the factors influencing the extent and diversity of household engagement in the extraction of forest products across different socio-economic groups remains limited. In this paper, we use primary data collected through a household survey of 180 households in a resettled dry forest areas of Northwestern Ethiopia. The…

Seed set and xenia effects on grain iron and zinc density in pearl millet
https://hdl.handle.net/10568/57486
Abstract
Three types of seed samples (selfed, sibbed and open pollinated) can be used for mineral analysis in pearl millet [Pennisetum glaucum (L.) R. Br.] and other crossâpollinated crops. Cost effectiveness and reliability of mineral estimates in these types of seed samples have a direct bearing on breeding efficiency. Three sets of experiments using a diverse range of materials were conducted to examine the potential use of…

Survey data of intra-household decision making and smallholder agricultural production in northern Uganda and southern Tanzania
https://hdl.handle.net/10568/82873
Abstract
This article provides a description of intra-household survey data that were collected in Uganda and Tanzania in 2014 and 2015, respectively. The surveys were implemented using a structured questionnaire administered among 585 households in Uganda and 608 in Tanzania. Information on decision making processes in agricultural production was collected from the…

Threats to cassava production: known and potential geographic distribution of four key biotic constraints
https://hdl.handle.net/10568/44186
Abstract
Insect pests and plant diseases reduce cassava yields substantially, posing a threat to food security throughout the developing world. While agricultural scientists have recognized these threats, few assessments of the geographic distribution of cassava pests and diseases have been made at the global scale. The goal of this study is to make such an evaluation for four key biotic…

Soil structural degradation and nutrient limitations across land use categories and climatic zones in Southern Africa
https://hdl.handle.net/10568/102161
Abstract
Although soil degradation is a major threat to food security and carbon sequestration, our knowledge of the spatial extent of the problem and its drivers is very limited in Southern Africa. Therefore, this study aimed to quantify the risk of soil structural degradation and determine the variation in soil stoichiometry and nutrient limitations with land use categories (LUCs…

Creating long-term weather data from thin air for crop simulation modeling
https://hdl.handle.net/10568/67076
Abstract
Simulating crop yield and yield variability requires long-term, high-quality daily weather data, including solar radiation, maximum (Tmax) and minimum temperature (Tmin), and precipitation. In many regions, however, daily weather data of sufficient quality and duration are not available. To overcome this limitation, we evaluated a new method to create long-term weather series based on a few years of observed daily…

Two Novel DNAs that enhance symptoms and overcome CMD2 resistance to cassava mosaic disease
https://hdl.handle.net/10568/73456
Abstract
Cassava mosaic begomoviruses (CMBs) cause cassava mosaic disease (CMD) across Africa and the Indian subcontinent. Like all members of the geminivirus family, CMBs have small, circular single-stranded DNA genomes. We report here the discovery of two novel DNA sequences, designated SEGS-1 and SEGS-2 (for sequences enhancing geminivirus symptoms), that enhance symptoms and break resistance to CMD. The…

Abstract
The diversity of bean producing areas in Africa in terms of environments and cropping systems and the nature of existing cultivars are briefly described. The lengths of growing seasons and rainfall, temperature and photoperiod during the growing seasons of bean producing areas are being characterized. These have been combined into an index to map the distributions of areas of…

Obstacles to integrated pest management adoption in developing countries
https://hdl.handle.net/10568/41884
Abstract
Despite its theoretical prominence and sound principles, integrated pest management (IPM) continues to suffer from anemic adoption rates in developing countries. To shed light on the reasons, we surveyed the opinions of a large and diverse pool of IPM professionals and practitioners from 96 countries by using structured concept mapping. The first phase of this method elicited 413 open-ended responses on perceived…

Prioritizing investments for climate-smart agriculture: Lessons learned from Mali
https://hdl.handle.net/10568/80477
Abstract
Agricultural productivity and growth in Mali are under threat from erratic rainfall, resulting in more frequent dry years. The national economy is vulnerable to climate change due to 50% of the gross domestic product coming from the agricultural sector and 75% of the population living in rural areas. The Climate-Smart Agriculture (CSA) concept arises from a need to provide innovative solutions towards the…

A Bayesian method to support global out-scaling of water-efficient rice technologies from pilot project areas
https://hdl.handle.net/10568/70261
Abstract
This article present a Bayesian probabilistic method to support out-scaling of technologies from pilot projects. The method is applied to aerobic rice, a water-saving technology with probable global potential. The method assumes that areas similar to pilot sites are more likely to adopt than those that are different or unfavourable. Similarity is defined from climate, landscape and…
