Boeng Sneh Lake, one of Prey Veng’s most important floodplain ecosystems, has reached a new milestone in its journey toward sustainable water and fisheries management. In late 2025, the District Technical Working Group (DTWG) in Ba Phnom successfully secured support from the Provincial Department of Water Resources and Meteorology (PDoWRAM) to replace the deteriorated water gate that regulates flows in and out of the lake. This achievement is far more than an infrastructure upgrade-it is a clear demonstration of how local cooperation, cross-sector dialogue, and community-centered planning can translate into real investment and tangible improvements for people and ecosystems.
Rice cultivation in Cambodia faces challenges from climate change, including intensifying droughts, erratic rainfall, and declining market prices, which undermine the sustainability of traditional monoculture systems. Integrated Rice-Field Pond (RFP) systems, piloted under the CGIAR–Asian Mega Delta initiative, offer a climate-smart alternative by transforming rice paddies into multifunctional, resilient micro-ecosystems. Strategically embedded ponds provide water security, enhance aquatic biodiversity, diversify food and income sources, and strengthen household resilience against climate shocks. Demonstrations under the CGIAR–Multifunctional Landscapes (MFL) program in Prey Veng and Kampong Thom highlight significant benefits: fish harvests through improved pond management, integrated farming profits were several times higher than rice monoculture, and household nutrition and dietary diversity improved. Community adoption has been strong, with low investment requirements enabling scalability to thousands of households. However, management gaps such as widespread pond draining, passive use, and inconsistent practice adoption, limit system resilience. Addressing these challenges requires targeted capacity building, improved governance, and national policy alignment to formally recognize RFPs as climate adaptation assets. Scaling the vision of “One Pond, One Family” could transform Cambodia’s rice landscapes into interconnected, biodiverse of productivity and resilience, securing livelihoods and food systems for millions of rural households.
The Inter-Provincial Workshop on Sharing and Dissemination of Results of Decentralized Governance of Food Systems, Food Security, and Nutrition in Cambodia was convened at the Prey Veng Provincial Administration. The workshop brought together 83 representatives from national and sub-national government institutions, development partners, research organizations, and community stakeholders to reflect on lessons learned and explore pathways for scaling decentralized food systems governance across Cambodia. The workshop was co-organized by the Council for Agriculture and Rural Development (CARD), WorldFish Cambodia, and the International Water Management Institute (IWMI), with support from CGIAR’s Scaling for Impact (S4I), Sustainable Animal and Aquatic Food (SAAF) and Multi-Functional Landscape (MFL) program. It focused on sharing experiences from the implementation of District Working Groups on Food Security and Nutrition (DWG-FSN) in Ba Phnom District (Prey Veng Province) and Santuk District (Kampong Thom Province), including ecosystem-based sub-working groups in Boeng Sneh Lake and Boeng Ream Community Fish Refuge (CFR)
Fish smoking in Madhya Pradesh is largely a women-driven activity. Indigenous fisherwomen are deeply involved in the entire value chain, from harvesting fish in rivers and reservoirs to processing, smoking, and selling the final product in local markets. In districts such as Mandla, Narmadapuram, Betul, and Jabalpur, this work plays a crucial role in household food security and income generation.
Rice is central to Cambodia’s food system and rural livelihoods, yet climate change and market volatility are increasingly undermining the sustainability of traditional rice monoculture. Evidence from Kampong Thom and Prey Veng under the CGIAR Multifunctional Landscapes program demonstrates that integrated rice-based systems offer a viable pathway toward more resilient and productive landscapes. By integrating rice, prawns, and vegetables within a single field, these systems transform conventional rice plots into multifunctional ecosystems that enhance farm income, nutrition, and ecological resilience. Through targeted field redesign, such as improved dikes, strategic canals, reduced chemical inputs, and careful environmental management, farmers can diversify production without compromising rice yields. Findings show that diversified rice systems outperform monoculture economically, nutritionally, and ecologically, proving that climate-smart innovations can deliver both technical feasibility and tangible livelihood benefits for Cambodian smallholders.
This report provides a general insight into IMTA farming systems and species from the Khulna district, with a focus on farmer practices, species management, health risks, and future opportunities for development. A variety of stakeholders were consulted to gather preliminary information on the current health status and key risk factors impacting the health of potential IMTA systems and species, including government institutions, researchers, farmers, as well as WorldFish employees involved in parallel aquaculture projects in Bangladesh. The Bangladesh Fisheries Research Institute (BFRI) in Bagerhat, the Department of Fisheries (DoF) in Khulna, and Khulna University (KU) were among the Bangladesh Government and research stakeholders approached for the health consultation. Farmers were visited in various locations in 3 upazilas of the Khulna district, namely Paikgacha, Dumuria and Batiaghata upazilas. Following the field visits, an introduction to future AABS IMTA health activities and a summary of the gathered information were presented to WorldFish Bangladesh staff in Dhaka, with whom information on selected aquatic species across different trophic levels was further discussed in breakout group sessions.
Malaysia’s aquaculture sector is undergoing a sustainability transition, driven by farmers experimenting with nature‑positive, climate‑smart and inclusive practices. The CAINA project, in partnership with Malaysian universities and supported by IDRC and the Government of Canada, is identifying what nature‑based aquaculture (NBA) looks like in practice, developing standards and tools to assess environmental, social, and economic impacts. By working directly with entrepreneurial farmers and conducting field case studies, the project highlights innovators advancing regenerative, low-impact approaches—from seaweed and shellfish systems to integrated multitrophic aquaculture—while mapping pathways to scale these models across Southeast Asia and the Pacific.
This document is a user guide designed to support aquaculture practitioners, extension officers, policymakers, and other stakeholders in effectively using the digital climate risk management tool for aquaculture.

Estimation and reduction of fish loss and waste (FLW) is essential for improving the contribution of fisheries and aquaculture to the achievement of national development objectives related to food security, income, employment, livelihoods and trade. Despite various FLW estimation and evaluation of interventions for loss reduction, a lack of consolidated data to support evidence-based investments and policy choices at national level still exist. The study aimed to evaluate FLW in low- and lower middle-income countries, identify gaps in assessment and examine causes and mitigation measures. A systematic review was performed using predefined criteria, and extracted quantitative data from eligible studies were used to calculate the average fish weight loss and the corresponding financial losses. The literature search was conducted without date restrictions. After applying the inclusion criteria and removing duplicates, 48 articles published between 1996–2024 were retained from an initial 247 for detailed analysis. Results indicate variation in estimated fish weight losses across various value chain stages. While small-scale FLW studies are more prevalent in Africa than in Asia or Latin America, data remains limited especially for distribution, marketing and consumption stages. In Africa, the greatest fish losses occur during processing (15%) and marketing (14.5%), while Asia fish loss is most pronounced during capture and distribution stages (12.6% and 10%, respectively). In Latin America, processing accounts for the largest share of losses (13%). Fish waste at the consumption stage is minimal (1.5%). Research focuses on small pelagic fish species, with most studies estimating physical losses. Assessment of quality, nutritional and financial losses are limited, and few studies incorporate gender disaggregated and responsive data. A multidimensional intervention approach is recommended to sustainably reduce losses, thereby ensuring food and nutrition security, while contributing to economic development.
Despite previous research on small fish (Dagaa) postharvest losses, a comprehensive assessment of the entire regional supply chain remains limited. The study aimed to quantify Dagaa losses, identify their causes and propose mitigation strategies. Using FAO’s load tracking method, Informal Fish Loss Assessment Method (IFLAM) and Questionnaire Loss Assessment Method (QLAM), we monitored changes in product weight, quality and nutritional profile. Results highlight processing and transportation as the most critical loss points. Processing stage accounted for 19.5%, 10% and 0.18 USD kg− 1 quality, physical and monetary loss, respectively primarily due to animal predation, poor drying infrastructure, and over-boiling. Losses increase during the rainy season due to reliance on sun drying. Transportation losses were significant (6%, 8% and 0.89 USD kg− 1 quality, physical and financial loss, respectively) caused by overloading, compression and mishandling. Landing delays during bargaining contributed to 2% quality loss, while storage and packaging quality losses were 4% and 3%, respectively, due to poor storage conditions and overstuffing practices. At the marketing stage, quality and physical losses reached 4% and 5%, respectively, owing to inappropriate storage infrastructure and mishandling. Consumption stage recorded 0.1% physical loss. Protein content of dried fish significantly declined following storage and transportation (P < 0.05). The micronutrients levels remained stable post storage and transportation. Mafia Island Fisheries lose about 15 million USD annually. A multidimensional intervention approach is recommended to reduce post-harvest losses. The study offers insights to guide government policies on food security and postharvest management, while supporting industry efforts to enhance efficiency, profitability and sustainability.
