Climate-Smart Agriculture Technologies and Determinants of Farmers’ Adoption Decisions in the Great Rift Valley of Ethiopia

Décembre, 2022
Ethiopia

Agriculture is a sector that is very vulnerable to the effects of climate change while contributing to anthropogenic greenhouse gas (GHG) emissions to the atmosphere. Therefore, applying Climate-Smart Agriculture (CSA) technologies and practices (referee hereafter as CSA technologies) that can sustainably boost productivity, improve resilience, and lower GHG emissions are crucial for a climate resilient agriculture. This study sought to identify the CSA technologies used by farmers and assess adoption levels and factors that influence them.

Improving phosphorus acquisition efficiency through modification of root growth responses to phosphate starvation in legumes

Décembre, 2022
Global

Phosphorus (P) is one of the essential macronutrients for plant growth and development, and it is an integral part of the major organic components, including nucleic acids, proteins and phospholipids. Although total P is abundant in most soils, a large amount of P is not easily absorbed by plants. Inorganic phosphate (Pi) is the plant-available P, which is generally immobile and of low availability in soils. Hence, Pi starvation is a major constraint limiting plant growth and productivity.

Global actions for Sustainable Rangelands and Pastoralism to achieve Land Degradation Neutrality

Décembre, 2022
Global

This presentation focuses on the global actions required to achieve Land Degradation Neutrality (LDN) through sustainable rangelands and pastoralism, aligning with the International Year for Rangelands and Pastoralists (IYRP) and its sub-working group on LDN. The challenges and threats to rangelands are outlined, emphasizing the climatic and anthropogenic pressures leading to natural resource degradation, productivity losses, and land-related conflicts.

Direct seeded rice: What are the benefits, potential and suitability in Haryana, India?

Décembre, 2022
India

Rice is one of the most widely grown cereal crops in India, providing primary nutrition as well as key livelihood and economic value – $23.3 billion in 2020. It is a water-intensive crop, however, and requires 1,000–2,000 millimeters of irrigation per cropping cycle, contributing to almost 40% of freshwater withdrawals in India. Most irrigation water is abstracted from groundwater, which relies on pumping that has led to a significant decline in the groundwater table in many places. Shifts in cultivation practices and management may foster greater sustainability.

Future scenarios of fish supply and demand for food and nutrition security in Bangladesh: An analysis with the AsiaFish model

Décembre, 2022
Bangladesh

Bangladesh has made significant progress in social and economic development in recent years, but micronutrient deficiencies and poor dietary diversity remain a significant challenge. This paper developed five scenarios to explore futures of fish supply-demand in Bangladesh using the AsiaFish model, with special emphasis on the role of fish in macronutrient and micronutrient supply to address the nation's malnutrition and nutrition security challenges. A business-as-usual (BAU) scenario followed historical trends for exogenous variables used in the model.

Digital transformation for more nutritious food systems: How digital tools can be used to scale and commercialize nutrient-enriched staple crops

Décembre, 2022
United States of America

This paper explains the need for digital tools and how they enable commercialization and scale, the impact on users, and the risks and benefits with examples of projects and partners along the value chain. This approach is being applied across all HarvestPlus activities and digital projects are researched and reported as part of the CGIAR Digital Innovation Initiative.

Seeds that give revisited: Participatory plant breeding and rural revitilization

Décembre, 2022
Global

In 2003, the International Development Research Centre (IDRC) of Canada published “Seed that give. Participatory plant breeding,” synthesizing the achievements and lessons learned of the first 10 (pioneering) years of participatory plant breeding (PPB), a concept first tabled at an international workshop in Wageningen, the Netherlands, in 1994. IDRC was one of the early and most fervent supporters of PPB. See: https://publications.gc.ca/site/eng/9.648982/publication.html

Phenotypic assessment of genetic gain from selection for improved drought tolerance in semi-tropical maize populations

Décembre, 2022
Global

Most maize production across the globe is rain-fed, and production is set to be negatively impacted as duration and occurrence of droughts increases due to climate change. Development of water-deficit tolerant maize germplasm has been a major focus for most breeding programmes. Here, we sought to assess the genetic gain for grain yield in two maize populations developed for drought tolerance at CIMMYT by evaluating their cycle progeny through hybrid performance.

Sustainability transitions in West African agriculture and food systems

Décembre, 2022

Scientific evidence is crucial for the transition towards sustainable and resilient agri-food systems. However, sustainability transitions research has been so far north-biased and overlooked the Global South. This paper analyses the scholarly literature on sustainability transitions in West African agriculture and food systems. In particular, it investigates the bibliometrics and geographical coverage of the research field and explores whether and how it addresses topics such as transition frameworks, niches, food security and sustainability.

Agronomic and economic performance of legume-legume and cereal-legume intercropping systems in Northern Tanzania

Décembre, 2022
Bahrain

CONTEXT
Cereal-legume intercropping, a common practice among farmers in sub-Saharan Africa (SSA), is important for crop diversification, soil fertility improvement, household nutrition and climate adaptation. However, cereals often outcompete the intercropped legumes for growth resources resulting in low legume yields.

Combining manure with mineral N fertilizer maintains maize yields: evidence from four long-term experiments in Kenya

Décembre, 2022
Kenya

Context
Crop productivity in sub-Saharan Africa cannot be substantially improved without simultaneously addressing short-term crop nutrient demand and long-term soil fertility. Integrated soil fertility management tackles both by the combined application of mineral fertilizers and organic resource inputs but few studies examined its‘ long-term effectiveness.
