Identifying determinants, pressures and trade-offs of crop residue use in mixed smallholder farms in Sub-Saharan Africa and South Asia
https://hdl.handle.net/10568/41615
Abstract
Crop residues (CR) have become a limited resource in mixed crop-livestock farms. As a result of the increasing demand and low availability of alternative resources, CR became an essential resource for household activities, especially for livestock keeping; a major livelihood element of smallholder farmers in the developing world. Farmers’ decisions on CR use…

Identification of presumed ancestral DNA sequences of phaseolin in Phaseolus vulgaris
https://hdl.handle.net/10568/73053
Abstract
Common bean (Phaseolus vulgaris) consists
oftwo major geographic gene pools, one distributed in Mexico,
Central America, and Colombia and the other in the southern
Andes (southern Peru, Bolivia, and Argentina). Amplification
and sequencing of members of the multigene family coding for
phaseolin, the major seed storage protein of the common bean,
provide evidence for accumulation of tandem direct repeats in…

Addressing gender in agricultural research for development in the face of a changing climate: where are we and where should we be going?
https://hdl.handle.net/10568/81543
Abstract
Agricultural development efforts that do not address persistent gender gaps miss opportunities for greater impact. This synthesis reflects on key findings from integrated quantitative and qualitative analyses at the nexus of gender, agricultural development, and climate change. Linked farm household-, intrahousehold-, community-, and institutional-level…

Genetic improvement in yield of semidwarf rice cultivars in Colombia
https://hdl.handle.net/10568/77775
Abstract
The narrowing gap between commercial and experimental yields in irrigated rice (Oryza sativa L.) has renewed interest in genetic yieldimprovement. Evaluation of past gains is useful for identifying areas with potential for further enhancement. Tall rice cultivar Bluebonnet 50, introduced semidwarfs ‘IR8’ and ‘IR22’, and 13 semidwarfs developed locally from 1971 to 1989 were grown in Colombia under irrigation and rainfed…

An expert system model for mapping tropical wetlands and peatlands reveals South America as the largest contributor
https://hdl.handle.net/10568/81497
Abstract
Wetlands are important providers of ecosystem services and key regulators of climate change. They positively contribute to global warming through their greenhouse gas emissions, and negatively through the accumulation of organic material in histosols, particularly in peatlands. Our understanding of wetlands’ services is currently constrained by limited knowledge on their…

Returns to food and agricultural R&D investments in Sub-Saharan Africa, 1975–2014
https://hdl.handle.net/10568/119691
Abstract
Research-enabled growth in agricultural productivity is pivotal to sub-Saharan Africa's overall economic growth prospects. Yet, investments in research and development (R&D) targeted to many national food and agricultural economies throughout Africa are fragile and faltering. To gain insight into what could be driving this trend, this article updates, summarizes and reassesses the published…

Smallholder farmers’ attitudes and determinants of adaptation to climate risks in East Africa
https://hdl.handle.net/10568/80194
Abstract
Adapting to climate risks is central to the goal of increasing food security and enhancing resilience of farming systems in East Africa. We examined farmers’ attitudes and assessed determinants of adaptation using data from a random sample of 500 households in Borana, Ethiopia, Nyando, Kenya, Hoima Uganda, and Lushoto, Tanzania. Adaptation was measured using a livelihood-based index that assigned…

Abstract
This paper examines the impact of participatory research and tests hypotheses on its effectiveness to increase the adoption of soil conservation and fertility management innovations in Southeast Asia. Participatory research activities are significant and positive in explaining the differential adoption rates of hedgerows, contour ridging, the usage of farm yard manure, and inorganic fertilizer over…

Abstract
Reconciling food security, economic development and biodiversity conservation is a key challenge, especially in the face of the demographic transition characterizing many countries in the world. Fisheries and marine ecosystems constitute a difficult application of this bio‐economic challenge. Many experts and scientists advocate an ecosystem approach to manage marine socio‐ecosystems for their sustainability and resilience. However, the…

A global surveillance system for crop diseases: global preparedness minimizes the risk to food supplies
https://hdl.handle.net/10568/102088
Abstract
To satisfy a growing demand for food, global agricultural production must increase by 70% by 2050. However, pests and crop diseases put global food supplies at risk. Worldwide, yield losses caused by pests and diseases are estimated to average 21.5% in wheat, 30.0% in rice, 22.6% in maize, 17.2% in potato, and 21.4% in soybean (1); these crops account for half of the global human calorie…

Alternative plant protein sources for pigs and chickens in the tropics - nutritional value and constraints: A review
https://hdl.handle.net/10568/33526
Abstract
In the tropics, a large number of smallholder farms contribute significantly to food security by raising pigs and poultry for domestic consumption and for sale on local markets. The high cost and, sometimes, the lack of availability of commercial protein supplements is one of the main limitations to efficient animal production by smallholders. Locally-grown forages and grain…
