Integral assessment of productive and environmental parameters of a forage-based silvopastoral system
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/103644
Abstract
Diversification of pastures and the incorporation of key plant functional groups (legumes) generally improve nutrient cycling and often lead to increased carbon sequestration in the soil. Furthermore, the inclusion of trees in the pastures improve soil properties while creating a microclimate more suitable for cattle…

Obstacles to integrated pest management adoption in developing countries
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
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…

Power and influence mapping in Ghana's agricultural adaptation policy regime
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
Debates around the design and content of climate change adaptation policies are shaped, in part, by the power and influence of actors within an adaptation regime. This paper applies a power-mapping technique, Multilevel Stakeholder Influence Mapping (MSIM), to stakeholders in Ghana's agricultural adaptation policy regime. The method provides a quantitative influence…

Genetic mitigation strategies to tackle agricultural GHG emissions: The case for biological nitrification inhibition technology
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
Accelerated soil-nitrifier activity and rapid nitrification are the cause of declining nitrogen-use efficiency (NUE) and enhanced nitrous oxide (N2O) emissions from farming. Biological nitrification inhibition (BNI) is the ability of certain plant roots to suppress soil-nitrifier activity, through production and release of…

Building a resilient city for whom? Exploring the gendered processes of adaptation to change: A case study of street vendors in Hanoi.
International Potato Center (CIP)
https://hdl.handle.net/10568/77386
Abstract
Drawing upon examples of street vendors in Hanoi, this study explores gendered strategies to adapt to change and transform, and how street vendors’ responses, in turn, shape the current informal food systems in Hanoi. To do this, the study employs gender analysis drawn from critical social theory. The…

Decision support tools for site-specific fertilizer recommendations and agricultural planning in selected countries in sub-Sahara Africa
World Agroforestry Centre (ICRAF)
Abstract
Recommendations and decisions of crop management in sub-Saharan Africa (SSA) are often based on traditional field experimentation. This usually ignores the variability of production factors in space and time, and hence invalidates such decisions and recommendations outside of the experimental sites. Yet, the use of alternative or complementary decision…

Synergistic interactions of begomoviruses with sweet potato chlorotic stunt virus (genus Crinivirus) in sweetpotato (Ipomoea batatas L.)
International Potato Center (CIP)
https://hdl.handle.net/10568/43657
Abstract
Three hundred and ninety‐four sweet potato accessions from Latin America and East Africa were screened by polymerase chain reaction (PCR) for the presence of begomoviruses, and 46 were found to be positive. All were symptomless in sweet potato and generated leaf curling and/or chlorosis in Ipomoea…

Changes in soil quality after subsequent establishment of Chromolaena odorata fallows in humid savannahs, Ivory Coast
World Agroforestry Centre (ICRAF)
Abstract
In the buffer zone of the Lamto Reserve, a protected area located in the forest-savannah transitional zone in central Ivory Coast, the exotic shrub Chromolaena odorata has invaded abandoned fields and degraded forests. As a result, they have turned into thickets that are used by local farmers as natural fallows to enhance soil fertility for food production. However,…

Agronomic use efficiency of N fertilizer in maize-based systems in sub-Saharan Africa within the context of integrated soil fertility management
World Agroforestry Centre (ICRAF)
Abstract
Traditionally, crop production in sub-Saharan Africa (SSA) depends primarily on mining soil nutrients. Integrated Soil Fertility Management (ISFM) is an approach for intensifying agriculture in SSA that aims at maximizing the agronomic efficiency (AE) of applied nutrient inputs. ISFM contains the following essential components: proper fertilizer…

Soil macrofauna in agricultural landscapes dominated by the Quesungual Slash-and-Mulch Agroforestry System, western Honduras
World Agroforestry Centre (ICRAF)
Abstract
Smallholder agroforestry systems often incorporate features that are associated with abundant, diverse soil macrofauna populations. This study sampled soil macrofauna communities across four major land uses present within agricultural landscapes where the Quesungual Slash-and-Mulch Agroforestry System (QSMAS) has been increasingly adopted by smallholder farmers in…

Landscape-scale variability of soil health indicators: effects of cultivation on soil organic carbon in the Usambara Mountains of Tanzania
World Agroforestry Centre (ICRAF)
Abstract
Land-use change continues at an alarming rate in sub-Saharan Africa adversely affecting ecosystem services provided by soil. These impacts are greatly understudied, especially in biodiversity rich mountains in East Africa. The objectives of this study were to: conduct a biophysical baseline of soil and land health; assess the effects of cultivation on…
