This study reports on the adoption and impacts of CGIAR-related maize varieties in 18 major maize-producing countries in sub-Saharan Africa (SSA) during 1995–2015. Of the 1345 maize varieties released during this timeframe, approximately 60% had a known CGIAR parentage. About 34% (9.5 million ha) of the total maize area in 2015 was cultivated with ’new’ CGIAR-related maize varieties released between 1995 and 2015. In the same year, an additional 13% of the maize area was cultivated with ’old’ CGIAR-related maize varieties released before 1995.

The International Maize and Wheat Improvement Center (CIMMYT) and partners are working to apply CRISPR technology to achieve a step-change in pearl millet seed product design: altering fatty acid metabolism to achieve the non-rancidity trait to create grain that when milled into flour has extended shelf life. Kenya is a country where the regulatory environment permits the introduction of gene-edited seed products when derived from site directed nuclease 1 and 2 derived technologies.

Sub-Saharan Africa is grappling with surging food demand amid a growing population and challenges of climate change. Climate Smart Agriculture (CSA) emerges as a holistic solution, aiming to counter these complexities and enhance livelihoods. However, the evidence remains thin and mixed. We used a meta-analysis with 18 studies to assess the impacts of climate smart agricultural practices on livelihood indicators in sub-Saharan Africa. We find that adoption of climate smart agriculture is positively correlated with crop and household income and food security in sub-Saharan Africa.

The adoption of sustainable agricultural mechanization (SAM) can sustainably increase productivity, and increase ecosystem resilience. Thirty (30) baby trials and One mother trial were established to expand access to smallholder farmers to SAM technologies and generate and share scientific evidence on the performance of SAM technologies, services and information in Ghana. The demonstration trials utilize participatory research and extension approaches by using existing partnerships.

This Synthesis Report (SYR) of the IPCC Sixth Assessment Report (AR6) summarises the state of knowledge of climate change, its widespread impacts and risks, and climate change mitigation and adaptation, based on the peer-reviewed scientific, technical and socio-economic literature since the publication of the IPCC’s Fifth Assessment Report (AR5) in 2014.

Se examina el context de la ganadería en una parte del complejo de paramo Chiles- Cumbal,Nariño, Colombia, su impacto asociado a la erosión del suelo, la pérdida de biodiversidad y las consecuencias para la seguridad alimentaria. Se identificaron varios factores clave, como la deficiente capacitación técnica de los productores en temas técnicos y ambientales, conflicto en el uso del suelo debido a diferencias sociales, y presencia de grupos al margen de la ley.

Maize is the staple food of most households in sub-Saharan Africa. The adoption of stress-tolerant maize varieties (STMV) is being promoted due to climate change. There are various methods applied to disseminate these varieties. Unfortunately, the adoption at the household level is still unsatisfactory. This study evaluated the effectiveness of the dissemination methods used in Benin. We identified dissemination methods from key informants involved in STMV seed dissemination projects.

Mungbean is an important pulse crop in Bangladesh, where it is primarily grown in the south by small and marginal farming households who produce two-thirds of the total national mungbean crop. Mungbean is a short-duration crop which requires only 60-65 days from planting to harvest. It is typically grown between February and May with few inputs or intensive management, and is thus growing in popularity in southern Bangladesh.

Background
An understanding of farmers' preferences of new banana cultivars and their characteristics is critical for developing and selecting cultivars that meet consumer needs. Therefore, phenotypic selection in a genetically variable population remains an important aspect of plant breeding.
