Item Excellence in Agronomy: Contribution to Kenya fertilizer access & nutrient use efficiency programme(Presentation, 2024-01) Nkomo, Mandlenkosi; Kinyua, Michael; Mathu, SamuelItem Feasibility of biochar technology to support the sustainable intensification and decarbonization of cocoa production in West-Africa(Presentation, 2024) Pulleman, Mirjam; Hougni, Deo-Gratias; Rahn, Eric; Barrio, Julian; Coppus, Ruben; Nguyen, Thuy Thanh; Roobroeck, dries; Talsma, TiffanyDecarbonization represents a major challenge for global commodity value chains, including cocoa. As biochar is increasingly presented as an effective carbon removal technology, it has attracted the attention of the chocolate industry. Moreover, potential agronomic and environmental benefits of biochar production and its utilisation in tropical soils could contribute to sustainable intensification of cocoa cultivation. Yet, scaling of biochar technologies has not yet been observed. We therefore explored the technical and environmental feasibility of biochar production in the context of smallholder cocoa farming in Ivory Coast and Ghana, responsible for more than 60% of the global supply. We combined extensive literature review with expert interviews to inform a carbon accounting model. The model calculates a carbon balance associated with different scenarios of biochar production and incorporation in soil under cocoa cultivation, compared to a baseline representing current practices. Next, we synthesised practical challenges and opportunities for adoption and scaling, based on the same interviews. The carbon removal potential of biochar is fully realised only if its production is coupled with bioenergetic applications that displace GHG emissions from non-sustainably sourced energy. In the most plausible scenario, the woody pruned residues and cocoa pod husks are gasified in improved cookstoves yielding ~20% biochar. Largest uncertainties arose from the use of fossil fuel powered machines for feedstock crushing, biochar grinding, and transport from and to conversion site. Additional challenges for scaling include labour demand, feedstock availability, application rates, equipment reproducibility at local scale, and lack of proven yield response. Opportunities include biochar co-composting in nutrient deficient soils, and application of biochar to seedlings exposed to drought conditions (nursery and replanting) and in light-textured, acidic soils. The study highlights consolidated knowledge and priorities for further research. Low technology readiness for current cocoa farmers, further exacerbated by economic challenges, will need to be addressed for farmers and industry to benefit from the opportunities of biochar.Item Food systems transformation through school meals: 8 things(Presentation, 2024-11-18) Hunter, DannyPresented at the Southeast Asia School Meals Summit: Accelerating Collaboration and Commitments in Southeast Asian Countries to Advance Human Capital Development and Food Systems Transformation in Siem Reap, Cambodia, between 18-20 November 2024.

Mediante la integración de cinco genes clave(Poster, 2024-06-12) Pineda, Marcela; Agrono, Tomas; Quintero, Constanza; Morales, Mabel; Alvarez, Maria FernandaThe fungus Pyricularia oryzae Cav., is the cause of the most important disease in rice cultivation, blast, due to its widespread presence in the world. Consequently, the development of rice plants tolerant to this disease is a key factor to maintain crop yields. By incorporating techniques such as marker-assisted selection (MAS) to screen genes of interest and the production of Double Haploid plants to generate homogeneous populations, we accelerate the development of resistant materials with several blast resistance genes. This study aims to obtain plants carrying five resistance genes to Pyricularia using molecular markers and tissue culture. Three parents were involved which have been identified as carriers of Pyricularia tolerance genes: CIFED 11 A (Pish, Pi2, and Piks-Zh), IRBLt-K59_LTH (Pi-t) and FL13032 (Pish and Pii). Two simple crosses were carried out (CIFED 11 A x IRBLt-K59 and CIFED 11 A x IRBLT-K59) and the F1 plants carrying the genes of each parent involved were selected, subsequently, A double cross was made between the two F1 to obtain a population of 1424 seeds that were planted to confirm the presence of the genes and with the selected plants the anther culture was carried out. In the tissue culture process, calluses were obtained, and plants were regenerated as a result of these. According to the phenotypic evaluation, double haploid plants were identified and evaluated to confirm the presence of the five resistance genes. Seven plants were confirmed as carriers of the genes of interest that present genotypic and phenotypic stability, which can be included in breeding program schemes for the generation of varieties tolerant to Pyricularia.Item Integrated school nutrition models: bridging school gardening, feeding and nutrition education(Presentation, 2024-09-21) Hunter, Danny; Gonsalves, Julian; Anunciado, S.; Castro, R.Presented at the Grassroots Partnerships for Pacific Solutions Conference in Nuku’alofa, Tonga, between 16-20 September 2024.

Key genomic tools and methodologies are discussed to enhance genetic diversity, selection accuracy, and breeding efficiency. The importance of characterizing genetic diversity within rice breeding programs is exemplified by studies such as genome-wide characterizations and the establishment of elite core panels to accelerate improvement rates. Marker-Assisted Selection (MAS) focuses on introgressing beneficial genes while recovering the genetic background efficiently. The process progresses through generations (e.g., BC1F1 to BC3F5), showcasing the superiority of MAS over traditional phenotypic selection. Advanced genotyping platforms like 1k-RiCA enable precise SNP-based analyses in genomic selection. This approach emphasizes optimizing training sets and leveraging predictive models to enhance genetic gain, as supported by recent achievements in rice breeding programs. Genomic tools are integral at every stage of the rice improvement process, reinforcing the need for robust foundational breeding programs.Item Epidemiología del complejo del achaparramiento del maíz en las zonas agroecológicas de Colombia(Poster, 2024-11-14) Arcila Bohórquez, Camila; Rodriguez Chalarca, Jairo; Bernal, Adriana; Reyes, Paola; Molina, JorgeItem Agroecological TRANSITIONS for our future(Infographic, 2025-01-15) TRANSITIONS Program; Ricci, Fabio; Araujo De Lima, Silvia; Shelton, Sadie; Geck, Matthias; Wollenberg, Eva Karoline; Mockshell, Jonathan; Crossland, MaryThis infographic was produced by the 3 projects' managers and communication officers of the TRANSITIONS Program (Agroecological transition programme for building resilient and inclusive agricultural food systems) funded by the European Union and managed by IFAD.

Innovative pathways for long-term incentives and private and public investmentItem Evaluación de prácticas agronómicas en la producción sostenible de arroz en siembra directa(Poster, 2024-06-13) Herrera, Cristian; Pineda, Marcela; Achipis, Jan; Alvarez, Maria FernandaThe conventional rice production system includes certain agronomic practices that have a negative impact on the conservation of non-renewable natural resources, such as soil and water. Agronomic practices such as intensive soil tillage, inefficient irrigation, excessive use of agrochemicals, and continuous rice-on-rice cropping contribute to the depletion of these resources. This study evaluates the effect of different agronomic practices on soil and water conservation in the direct seeding rice system. Two study areas with contrasting production histories (rice-rice and sugarcane-maize) were selected, and four rice plantings were conducted over two years. Measurements were taken for various soil variables, such as bulk density, penetration resistance, chemical analysis, organic matter content, and total carbon, as well as water variables, including total usage per cycle, accumulated precipitation, and irrigation frequency.Item Optimizando el mejoramiento del Arroz: Plataforma de avance generacional rápido en el HIAAL(Poster, 2024-06-13) Torres, Juanita; Carabali, Silvio James; Alvarez, Maria FernandaThe Rapid Generation Advancement (RGA) Platform has been established with the primary purpose of accelerating the fixation process of improved lines for subsequent selection in breeding programs. This approach aims to develop fixed improved lines in less time, generating new parental combinations with the necessary traits to ensure crop stability and profitability. Reducing the time required for breeding processes and improving the precision in selecting improved lines are key parameters that ensure an increase in the rate of genetic gain. This study aims to describe the progress of the Hybrid Rice for Latin America (HIAAL) consortium in obtaining lines in less time by using the RGA platform. HIAAL seeks to facilitate producers' access to hybrid rice technology through research and partnerships with the public and private sectors in Latin America. Within this context, it conducts work to improve the parental lines of these hybrids. To achieve this, 24 crosses were carried out, generating combinations among the 10 most heterotic parents of the consortium. These crosses were advanced from the F1 to the F5 generation within the facilities of the RGA platform. Subsequently, each line was multiplied in the field to evaluate its resistance to white leaf virus and Pyricularia. The selection process resulted in 405 lines being chosen for evaluation in hybrid cross trials. The RGA platform significantly contributes to the consortium, as it allows a large number of cross trials to be conducted in less time, thereby determining the genetic value of the parentals and ensuring the optimal recycling of parentals.Item Protocolo de detección de Spiroplasma kunkelii (CSS) en Dalbulus maidis(Poster, 2024-11-14) Arcila Bohórquez, Camila; Rodriguez Chalarca, Jairo; Bernal, Adriana; Reyes, PaolaItem Mejoramiento del arroz biofortificado para América Latina ganancia genética en rendimiento y contenido de zinc(Poster, 2024-06-06) Bartholomé, Jerome; Borrero, Jaime; Sandoval, Leydi; Alvarez , Maria Fernanda; Grenier, CecileThe growing global demand for rice drives the search for new materials with high yields, resistance to pests and diseases, grain quality, and high nutritional content. For over 20 years, the biofortified rice program of CIAT and later the Alliance has contributed to global food security by developing lines with greater nutritional value and high agronomic quality standards.The objective of this work is to describe the program, its evolution, and its achievements. Over time, the program has identified and distributed high-potential lines to various partners. Additionally, it has incorporated breeding strategies aimed at increasing the genetic gain of zinc content by at least 1.86% per year.The program's first phase began with the Agrosalud project in 2005, which sought to increase iron and zinc content in polished rice grains. Since then, nutritional quality has been included as a selection criterion, and evaluation protocols have been established. Subsequently, around 2013, another phase started, during which the zinc content of over 2,000 accessions from the germplasm bank was analyzed. Once the best genotypes were identified, advanced biofortified lines were developed through crossings and selection schemes, which were evaluated in multi-environment trials.Thanks to the collaboration of entities such as CIRAD, HarvestPlus, and INIAS from different countries, four varieties have been released in Latin America. This joint effort has even crossed borders, enabling the release of a high-zinc variety in Mali, Africa. Currently, the program continues to advance in diversification and genetic gain through breeding processes and tools, such as the use of molecular markers, DNA sequencing, and genome editing. These efforts not only aim to develop new lines but also to encourage partner participation in improving the program.Item GTRM-CoP Intersectionality conversation: Dimitra Clubs - What is the role of community engagement in gender-transformative change?(Presentation, 2024-08-02) Monsieur, Christiane; Sanchez Enciso, Andrea; Bailey, ArwenFor many years, FAO has championed a community-driven approach centered on facilitating the engagement of rural communities—through dialogue and action—as catalysts for their own development. Known as Dimitra Clubs, this approach aims to promote rural people’s empowerment while enhancing women's leadership and gender equality. The Dimitra Clubs model is a powerful means for the Organization to deliver on the principles of “Leaving No One Behind” and “Gender Equality” in agrifood systems transformation. This webinar looks at gender-transformative change through the lens of intersectionality.Item Linguistic diversity, climate shock, and farmer-herder conflicts(Presentation, 2024-08-01) Song, Chun; Petsakos, Athanasios; Gotor, Elisabetta
