Soil conservation and smallholder welfare under cassava-based systems in Thailand
https://hdl.handle.net/10568/127068
Abstract
Land degradation, declining soil fertility, and erosion continue to plague agricultural production in many developing countries. In response to these farm production constraints and environmental challenges, a range of soil conservation technologies and practices have been developed and disseminated to tackle soil nutrient and fertility declines. However, evidence on the association between soil conservation…

Participatory action research, social networks, and gender influence soil fertility management in Tanzania
https://hdl.handle.net/10568/119647
Abstract
Transformation of knowledge systems and fostering learning among smallholder farmers such as through participatory action research (PAR) is key to agricultural growth in rural sub-Saharan Africa. We investigate how PAR influences uptake/use of integrated soil fertility management (ISFM) while accounting for gendered, bonding and bridging social capital. Stratified by engagement in a…

Climate change effects on pathogen emergence: Artificial intelligence to translate big data for mitigation
https://hdl.handle.net/10568/119779
Abstract
Plant pathology has developed a wide range of concepts and tools for improving plant disease management, including models for understanding and responding to new risks from climate change. Most of these tools can be improved using new advances in artificial intelligence (AI), such as machine learning to integrate massive data sets in predictive models. There is the potential to…

Reference soil groups map of Ethiopia based on legacy data and machine learning technique: EthioSoilGrids 1.0
https://hdl.handle.net/10568/119860
Abstract
Abstract. Up-to-date digital soil resources information, and its comprehensive understanding, is crucial to support crop production and sustainable agricultural development. Generating such information through conventional approaches consumes time and resources, which is difficult for developing countries. In Ethiopia, the soil resource map that was in use is qualitative, dated (…

Using ENSO conditions to optimize rice yield for Nepal’s Terai
https://hdl.handle.net/10568/120402
Abstract
The direct application of forecasts from seasonal prediction systems (SPSs) in agriculture is limited by their skill, and SPSs are more skilled at El Niño-Southern Oscillation (ENSO) prediction than precipitation prediction. An alternative to the direct application of forecasts from SPSs could be to link the forecast of ENSO conditions with dynamic crop models to evaluate alternate crop management options prior to the start of…

High throughput sequencing for the detection and characterization of new virus found in arracacha (Arracacia xanthorrhiza)
https://hdl.handle.net/10568/119213
Abstract
Arracacha is a root crop cultivated in several countries of South America. The commercial product, which is the storage root, has multiple nutritional properties: its fine starch makes it easily digestible, and it contains high levels of calcium and vitamin A. High throughput sequencing (HTS) technology has been applied successfully for virus discovery in different…

Abstract
Purpose of Review
Recognizing that in the context of global change, tree genetic diversity represents a crucial resource for future forest adaptation, we review and highlight the major forest genetics research achievements of the past decades in biodiversity-rich countries of the Mediterranean region. For this, we conducted a bibliometric analysis of the scientific literature…

Abstract
Climate disasters affect human security and development, moreso in fragile and conflict-affected contexts where population’ capacities to cope with climate change are compromised. Responses to such crises lie at the nexus of humanitarian assistance, development, and peacebuilding. Yet, there are still too few integrated programmatic responses coordinating peacebuilding and climate actions to…

From Within and Without: Gender, agency and sustainable management of non-timber forest products in two Indian States
https://hdl.handle.net/10568/125649
Abstract
Non-timber forest products (NTFP) from trees are often collected using unsustainable practices, which contributes to the species’ decline and affects the livelihoods and wellbeing of the most forest-dependent groups, such as women, ethnic minorities and the landless. Here we assess opportunities to improve the sustainability of NTFP collection practices across two…

Abstract
Grassland pastures are crucial for the global food supply through their milk and meat production; hence, forage species monitoring is essential for cattle feed. Therefore, knowledge of pasture above-ground canopy features help understand the crop status. This paper finds how to construct machine learning models to predict above-ground canopy features in…

Abstract
In this research, we explored rainfall variability in the Sogamoso River Basin (SRB), its relationship with multiple scales of variability associated with El Niño–Southern Oscillation (ENSO), and the implications for rainfall prolongation during multiyear La Niña events. First, we examined time-frequency rainfall variations in the…
