Methane emission, carbon footprint and productivity of specialized dairy cows supplemented with bitter cassava (Manihot esculenta Crantz)

Diciembre, 2023
Global

The objective of this research was to determine the effect of cassava (Manihot esculenta Crantz) supplementation on enteric methane (CH4) emissions, carbon footprint, and production parameters in dairy cows. Daily concentrate supply for Jersey and Jersey * Holstein breeds was evaluated in four treatments (T): T1: 100% commercial concentrate; T2: 70% concentrate + 30% cassava leaves; T3: 70% concentrate + 30% cassava roots; and T4: 70% concentrate + 15% cassava leaves + 15% cassava root chips. Measurements of CH4 emissions were performed using the polytunnel technique.

Automated in-season rice crop mapping using Sentinel time-series data and Google Earth Engine: A case study in climate-risk prone Bangladesh

Diciembre, 2023
Bangladesh

High-resolution mapping of rice fields is crucial for understanding and managing rice cultivation in countries like Bangladesh, particularly in the face of climate change. Rice is a vital crop, cultivated in small scale farms that contributes significantly to the economy and food security in Bangladesh. Accurate mapping can facilitate improved rice production, the development of sustainable agricultural management policies, and formulation of strategies for adapting to climatic risks.

Understanding diversity in gender norms within farming communities: A Q-methodology approach applied in Uganda

Diciembre, 2023
Uganda

Women’s and men’s opportunities are influenced by gender norms which shape their respective behaviours, roles and decision-making power. Gender norms thus influence farming outcomes and the ability of women and men to secure their livelihood objectives. We study gender norms and normative change in a smallholder farming community in Uganda. We argue that gender norms operate in sets and that multiple sets of gender norms may co-exist in the same location.

Development of methods for improving flowering and seed set of diverse germplasm in cassava breeding

Diciembre, 2023
Global

Cassava breeding faces obstacles due to late flowering and poor flower and seed set. The acceleration of breeding processes and the reduction in each cycle’s duration hinge upon efficiently conducting crosses to yield ample progeny for subsequent cycles. Our primary objective was to identify methods that provide tools for cassava breeding programs, enabling them to consistently and rapidly generate offspring from a wide array of genotypes. In greenhouse trials, we examined the effects of the anti-ethylene silver thiosulfate (STS) and the cytokinin benzyladenine (BA).

Group-based and citizen science on-farm variety selection approaches for bean growers in Central America

Diciembre, 2023
Global

Participatory approaches for crop variety testing can help breeding teams to incorporate traditional knowledge and consider site-specific sociocultural complexities. However, traditional participatory approaches have drawbacks and are seldom streamlined or scaled. Decentralized on-farm testing supported by citizen science addresses some of these challenges.

Response to heat stress and glutenins allelic variation effects on quality traits in durum wheat

Diciembre, 2023
Global

In the context of climate change, high temperature is one of the main abiotic stresses hampering durum wheat production. Through the characterization of an international panel of 271 genotypes, this study investigates the effects of heat stress on quality traits and identifies which glutenins (Glu-1, Glu-2 and Glu-3 loci) alleles are the most important to obtain high gluten strength under optimal and high temperature conditions.

Double-booked: Effects of overlap between school and farming calendars on education and child labor

Diciembre, 2023
United States of America

Across sub-Saharan Africa, countries with a greater percentage of overlapping days in their school and farming calendars also have lower primary school survival rates. In theory, greater overlap between the school and farming calendars should indeed reduce schooling investments, and farm-based child labor too, as it constrains the time allocation opportunity set for both productive activities.

Genomic regions of durum wheat involved in water productivity

Diciembre, 2023
Global

Durum wheat is a staple food of the Mediterranean Basin, mostly cultivated under rainfed conditions. As such, the crop is often exposed to moisture stress. Therefore, the identification of genetic factors controlling the capacity of genotypes to convert moisture into grain yield (i.e., water productivity) is quintessential to stabilize production despite climatic variations. A global panel of 384 accessions was tested across eighteen Mediterranean environments (Morocco, Lebanon, and Jordan) representing a vast range of moisture levels.

Opportunities for innovation and intervention in Uganda’s dairy value chain: A scoping report

Diciembre, 2023
United States of America

This report is generated as part of a scoping study to identify possible areas that should be prioritized for intervention to improve performance and sustainability of the dairy industry in Uganda. The evaluation relies on primary and secondary data collected by IFPRI and DDA in 2021. Ten primary datasets are used for the results informing the several interventions and secondary data relies on literature review and Uganda Revenue Authority (URA) dataset. The results underline five issues namely low productivity, low milk quality, and constrained markets.

Extreme weather and undernutrition: A critical but constructive review of the literature

Diciembre, 2023
United States of America

Climate change is resulting in increased frequency of extreme weather events, especially in low- and middle-income countries (LMICs) already characterized by highly vulnerable malnourished populations. Unsurprisingly, there are many empirical studies of the linkages between extreme weather events and undernutrition, especially stunting and wasting in early childhood, and several existing reviews of this literature.

The tricot approach: an agile framework for decentralized on-farm testing supported by citizen science. A retrospective

Diciembre, 2023
Global

Matching crop varieties to their target use context and user preferences is a challenge faced by many plant breeding programs serving smallholder agriculture. Numerous participatory approaches proposed by CGIAR and other research teams over the last four decades have attempted to capture farmers’ priorities/preferences and crop variety field performance in representative growing environments through experimental trials with higher external validity.
