Agricultural transformation in maize producing areas of Africa

Dezembro, 2023
Global

Maize is a critical staple cereal across Sub-Saharan Africa but attempts to improve its productivity in small-scale farming systems often prove disappointing. The 12 key technologies required to overcome poor yields are mostly known, but the manner that they are mobilized, packaged, and delivered requires re-evaluation. Combinations of better varieties and their necessary accompanying inputs must become more available and affordable for an African maize revolution to succeed, and land must be managed in ways that enhance, rather than diminish, land quality over time.

Global methane pledge in Tajikistan: Assessment report

Dezembro, 2023
Tajikistan

The Government of Tajikistan should consider joining the Global Methane Commitment as a strategic and prudent decision. Tajikistan's participation in the Global Methane Pledge offers numerous benefits that can positively impact the country's economy, environment, and global reputation. By joining this international effort to reduce methane emissions, Tajikistan can contribute to global climate change mitigation goals, demonstrating its commitment to addressing environmental challenges.

Closing gender gaps through gender-responsive, demand-led breeding in Burundi

Dezembro, 2023
Burundi

Gender inequality persists in Burundi’s agricultural sector, especially in the bean value chain dominated by women. Women often have less access to improved seeds and to productive technologies. Interventions dubbed “gender-responsive plant breeding” have been launched to develop new varieties to address the gender gaps in variety adoption. Gender responsive planting breeding in Burundi targets to develop bean varieties that respond better to gendered varietal and trait preferences.

Towards the harmonization of global environmental flow estimates: comparing the Global Environmental Flow Information System (GEFIS) with country data

Dezembro, 2023
Global

The source of data used to estimate the e-flow requirement in Sustainable Development Goal (SDG) Indicator 6.4.2 (level of water stress: freshwater withdrawal as a proportion of available freshwater resources) is the Global Environmental Flow Information System (GEFIS), an online tool produced and managed by the International Water Management Institute (IWMI).

Pakistan: Strategy to promote climate smart agriculture practices

Dezembro, 2023
Pakistan

Pakistan is a case of double injustice contributing a minuscule share of global greenhouse gases, yet it is bearing the brunt of global climate change impacts. It ranks among the top 10 countries vulnerable to climate change (Eckstein et al., 2021). The 2022 IPCC Report underlines the heightened vulnerabilities because of global warming and climate change leading to more floods. The Asia-Pacific Disaster Report 20221, Pakistan could lose more than 9 percent of its annual GDP due to climate change.

Terms of Reference: CGIAR Science Group Evaluations

Dezembro, 2023
Global

The evaluation function of the Independent Advisory and Evaluation Services (IAES), is executing the 2024 evaluations of the three Science Groups (SGs)—Systems Transformation (ST), Resilient Agrifood Systems (RAFS), and Genetic Innovation (GI). The evaluation Terms of Reference (TORs), which are endorsed by the Strategic Impact, Monitoring, and Evaluation Committee (SIMEC) and build on the Concept Note, are presented to the CGIAR System Council (SC19) as a pre-read.

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

Dezembro, 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

Dezembro, 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

Dezembro, 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.

Human-nature interactions in the Afrotropics: experiential and cognitive connections among urban residents in southern Nigeria

Dezembro, 2023
Nigeria

Many people are losing direct contact with nature, a phenomenon termed as the extinction of experience. Urban dwellers are particularly affected by this process that influences public health and habitat conservation. We explored the extinction of experience among the urban populace in Nigeria, a clear Global South representative with rapidly increasing human population. We interviewed 600 adults from several cities and performed statistical tests. Results show that most respondents have no contact nor connection with nature, revealing an important distancing from the natural world.

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

Dezembro, 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

Dezembro, 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.
