Can mobile phone-based animated videos induce learning and technology adoption among low-literate farmers? A field experiment in Burkina Faso
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
This article explores an innovative approach to deliver information about new agricultural technology that combines a versatile and potentially lower cost method of developing animated videos with another low-cost method of sharing it on mobile devices (i.e. mobile phone). It describes a randomized controlled…

High temperature tolerance in grain legumes
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
High temperature stress (or heat stress) during reproductive stages is becoming aserious constraint toproductivity of grain legumes as their cultivation is expanding to warmer environments and temperature variability is increasing due to climate change.Large genetic variations exist ingrainlegumesforheat tolerance whichcan be exploited for development of locally adapted heat tolerant cultivars. Heat tolerant…

Nitrogen management in grasslands and forage-based production systems ? Role of biological nitrification inhibition (BNI)
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
Nitrogen (N), the most critical and essential nutrient for plant growth, largely determines the productivity in both ex-tensive and intensive grassland systems. Nitrification and denitrification processes in the soil are the primary drivers of generating reactive N (NO3-, N2O and NO), largely responsible for N loss and degradation…

The Agricultural Model Intercomparison and Improvement Project (AgMIP): Integrated Regional Assessment Projects
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
The worldwide agricultural sector faces the significant challenge of increasing productionto provide food security for a population projected to rise to nine billion bymid-century, while protecting the environment and the sustainable functioning ofecosystems. This challenge is compounded by the need to adapt to climate changeby taking…

Developing climate-smart agriculture to face climate variability in West Africa: Challenges and lessons learnt
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
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…

Fertilizer response and nitrogen use efficiency in African smallholder maize farms
World Agroforestry Centre (ICRAF)
Abstract
Improving fertilizer recommendations for farmers is essential to increase food security in smallholder landscapes. Currently, blanket recommendations are provided across agro-ecological zones, although fertilizer response and nutrient use efficiency by maize crop are spatially variable. We aimed to identify factors that could help to refine fertilizer recommendation by analyzing the variability in fertilizer…

Effect of Farmers’ Multidimensional Beliefs on Adoption of Biofortified Crops Evidence from Sweetpotato Farmers in Tanzania
International Potato Center (CIP)
https://hdl.handle.net/10568/90959
Abstract
We examined the effect of multidimensional farmers’ beliefs on the likelihood of cultivating planting materials of biofortified orange-fleshed sweetpotato (OFSP) varieties. Using a panel dataset and combining difference-in-differences regression with propensity score matching, results showed positive effects of…

Long term effects of reduced fertilizer rates on millet yields and soil properties in the West-African Sahel
World Agroforestry Centre (ICRAF)
Abstract
Microdosing, the point-source application of a reduced fertilizer rate within 10Â days of sowing, has increased short-term crop yields across the Sahel and is being actively scaled up as an agronomic practice. However, there is no information on the long-term effects of the technique upon soil fertility. To rectify this, this study used soil samples from the International Crop…

Smallholder farmers? attitudes and determinants of adaptation to climate risks in East Africa
World Agroforestry Centre (ICRAF)
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…

Abstract
Quantifying relationships between plant functional traits and abiotic gradients is valuable for evaluating potential responses of forest communities to climate change. However, the trajectories of change expected to occur in tropical forest functional characteristics as a function of future climate variation are largely…

Abstract
Much biodiversity data is collected worldwide, but it remains challenging to assemble the scattered knowledge for assessing biodiversity status and trends. The concept of Essential Biodiversity Variables (EBVs) was introduced to structure biodiversity monitoring globally, and to harmonize and standardize…
