Market‐led options to scale up legume seeds in developing countries: Experiences from the Tropical Legumes Project
https://hdl.handle.net/10568/102179
Abstract
There are several hurdles to ensure sustainable seed production and consistent flow of improved legume varieties in sub‐Saharan Africa (SSA) and South Asia (SA). The unreliable demand, autogamous nature of most of the grain legumes, and slow variety replacement rate by smallholder farmers do not provide strong incentive for private seed companies to invest in legume seed…

Conservation agriculture and livelihoods of smallholder farmers in central Mozambique
https://hdl.handle.net/10568/43297
Abstract
This article demonstrates how conservation agriculture impacts smallholder farmers' livelihoods in Mozambique through increased crop productivity and yields, using primary data on smallholder farmers practicing conservation agriculture and others not using this technology from Nhanguo, Pumbuto, and Ruaca in Manica and Sofala provinces. Data analysis employs semiparametric propensity score matching…

Sustainable intensification: What is its role in climate smart agriculture?
https://hdl.handle.net/10568/42347
Abstract
The ‘sustainable intensification’ (SI) approach and ‘climate-smart agriculture’ (CSA) are highly complementary. SI is an essential means of adapting to climate change, also resulting in lower emissions per unit of output. With its emphasis on improving risk management, information flows and local institutions to support adaptive capacity, CSA provides the foundations for incentivizing and enabling intensification.…

Genetic base of irrigated rice in Latin America and the Caribbean 1971 to 1989
https://hdl.handle.net/10568/77776
Abstract
The trend to commercially exploit a reduced genetic base in most crops has raised concerns about the possibility of large yield reductions as a result of environmental disturbances. This study describes the genetic base of irrigated rice (Oryza sativa L.) from Latin America and the Caribbean. Schematic pedigrees of 143 cultivars released between 1971 and 1989 were constructed, and releases were grouped by the…

Interactive effects of altitude, microclimate and shading system on coffee leaf rust
https://hdl.handle.net/10568/102486
Abstract
Shade effects on coffee diseases are ambiguous because they vary depending on the season and environment. Using Coffee Leaf Rust (CLR) as an example, we demonstrate relationships between the environment and shading systems and their effects on disease intensity. We characterized seasonal variations in microclimate and CLR incidence across different altitudes and shading
systems, and integrated effects…

Developing climate-smart agriculture to face climate variability in West Africa: challenges and lessons learnt
https://hdl.handle.net/10568/91938
Abstract
This paper reviewed the prospects for climate-smart agriculture (CSA) development and promotion in West Africa as well as lessons learnt and challenges with a focus on climate change and variability. It was evident from the literature that West Africa is vulnerable to climate change and variability, on account of its socio-economic and physical characteristics. As climate change…

A global spectral library to characterize the world’s soil
https://hdl.handle.net/10568/70992
Abstract
Soil provides ecosystem services, supports human health and habitation, stores carbon and regulates emissions of greenhouse gases. Unprecedented pressures on soil from degradation and urbanization are threatening agro-ecological balances and food security. It is important that we learn more about soil to sustainably manage and preserve it for future generations. To this end, we developed and analyzed a global soil visible–near…

The climate of cloud forests
https://hdl.handle.net/10568/42481
Abstract
This chapter analyses the climatic conditions prevailing at sites where tropical montane cloud forests (TMCF) have been reported. Spatial data-sets of climate were used to describe the climate at 477 cloud forest sites identified by United Nations Environment Program (UNEP)-WCMC. Some 85% of the sites are found at altitudes between 400 and 2800 m a.s.l., with an average altitude of 1700 m. The range of altitudes at which cloud forests are found is extensive (220…

Abstract
Forage-based livestock production plays a key role in national and regional economies, for food security and poverty alleviation, but is considered a major contributor to agricultural GHG emissions. While demand for livestock products is predicted to increase, there is political and societal pressure both to reduce environmental impacts and to convert some of the…

Abstract
Empirical scientific evidence indicates that there is still room for increasing food production by improving land productivity. This study aimed at identifying the key determinants that govern farmers’ decisions to adopt multiple components of integrated soil fertility management (ISFM) in a maize mixed cropping system of the Chinyanja Triangle, Southern Africa. Revealed…
