Drought susceptibility of modern rice varieties : an effect of linkage of drought tolerance with undesirable traits
(Nature Publishing, 2015)
Green Revolution (GR) rice varieties are high yielding but typically drought sensitive. This is partly due to the tight linkage between the loci governing plant height and drought tolerance. This linkage is illustrated ...
Evidence and lessons learned from Long-Term On-Farm Research on Conservation Agriculture Systems in communities in Malawi and Zimbabwe
A long-term study was carried out in the Zidyana Extension Planning Area (EPA), Malawi and in the Zimuto Communal Area, Zimbabwe, to evaluate the effect of different conservation agriculture (CA) systems on crop productivity, ...
Where to target conservation agriculture for african smallholders? How to overcome challenges associated with its implementation? experience from Eastern and Southern Africa
Since the paper by Giller et al. (2009), the debate surrounding the suitability of conservation agriculture (CA) for African smallholders has remained polarized between proponents and opponents. The debate also gave rise ...
Tillage, residue and nitrogen management effects on methane and nitrous oxide emission from rice–wheat system of Indian Northwest Indo-Gangetic Plains
(Taylor and Francis; European Federation of Associations of Environmental Professionals; European Federation of Engineering Consultancy Associations; Vereniging van Milieuprofessionals, 2015)
Zero-tillage, residue management and precision nutrient management techniques are being promoted in the rice–wheat (RW) production system of Indo-Gangetic Plains (IGPs) to enhance climate change adaptation and increase ...
A short-term assessment of carbon dioxide fluxes under contrasting agricultural and soil management practices in Zimbabwe
(Canadian Center of Science and Education, 2015)
Two of the biggest problems facing humankind are feeding an exponentially growing human population and preventing the accumulation of atmospheric greenhouse gases and its climate change consequences. Refined agricultural ...
Beyond conservation agriculture
(Forntiers Media, 2015)
Global support for Conservation Agriculture (CA) as a pathway to Sustainable Intensification is strong. CA revolves around three principles: no-till (or minimal soil disturbance), soil cover, and crop rotation. The benefits ...
Improving rural livelihoods as a "moving target": trajectories of change in smallholder farming systems of Western Kenya
(Springer Verlag, 2015)
Understanding the diversity of current states, life cycles and past trajectories of households and agroecosystems is essential to contextualise the co-design of more sustainable agroecosystems. The objective of this paper ...
Weed dynamics and conservation agriculture principles : a review
Conservation agriculture (CA) is based on minimum soil disturbance, permanent soil cover, and crop rotation; it is promoted as a sustainable alternative to systems involving conventional tillage. Adoption of CA changes ...
"Filling the maize basket" supports crop diversity and quality of household diet in Malawi
(Springer Nature, 2015)
Food security and dietary quality are broadly supported development goals, yet few studies have addressed how agricultural subsidy policies and promotion of modern crop varieties impact smallholder farm production and ...
Identifying pathways for improving household food self-sufficiency outcomes in the Hills of Nepal
(Public Library of Science, 2015)
Maintaining and improving household food self-sufficiency (FSS) in mountain regions is an ongoing challenge. There are many facets to the issue, including comparatively high levels of land fragmentation, challenging terrain ...
