Book (stand-alone)GuidelineGuidance document: Advancing end-to-end traceability
Critical tracking events and key data elements along capture fisheries and aquaculture value chains
2023Also available in:
The Guidance document: “Advancing end-to-end traceability along capture fisheries and aquaculture value chains” responds to a critical need for consensus towards establishing end-to-end traceability through globally agreed and standardized understanding of the critical tracking events (CTEs) along the fish value chain, as well as sources of key data elements (KDEs) related to fish production and product identification. In particular, the Guidance aims at developing insights and addressing gaps in developing and implementing traceability systems for both the private sector and government. Supported by deliberations through various consultations between 2021 and 2022, it also provides technical advice in the enforcement and adequate verification of traceability in fish value chains and seeks to act as a benchmark of existing traceability systems to evaluate their efficacy and identify associated gaps. The document addresses these objectives through the identification of CTEs and KDEs along the fish value chain (sections 3 and 4) and, where possible, the identification of supporting standards based on the standards and guidelines of the Global Dialogue on Seafood Traceability (GDST). It includes discussion and recommendation narrative (sections 5 and 6) whereby the overarching takeaways and advice is to: a) identify and define standardized KDEs and CTEs for commercial and regulatory traceability; and b) follow strict due diligence using a holistic and integrated approach involving all stakeholders at legal, commercial and operational level prior to commitment. -
BookletCorporate general interestStandard operating procedure for soil pH determination 2021
Also available in:
Soils are referred to as being acid, neutral, or alkaline, depending on their pH, with 7 being neutral, below 7 acidic and above 7 alkaline. The pH range normally found in soils varies from 3 to 9. As pH is measured in terms of hydrogen ion activity, pH is thus a measure of only the intensity of H+ activity and not the amount of acidity present. The desirable soil pH range for optimum plant growth varies among crops. Generally, a soil pH between 6.0-7.5 is acceptable for most plants, as most nutrients are available in this pH range. However, some plants have soil pH requirements above or below this range. An acidic pH may cause higher mobility of toxic elements potentially leaching into ground water or taken up and accumulated in plants. Additionally, inhibited plant growth may be observed in low pH soils due to aluminum toxicity. In higher pH soils, phosphorus and most micronutrients may become less available. As the pH value of many soils correlates with base saturation, it may also be used in the field for preliminary classification purposes. -
Book (series)FlagshipThe State of World Fisheries and Aquaculture 2024
Blue Transformation in action
2024The 2024 edition of The State of World Fisheries and Aquaculture features the Blue Transformation in action, illustrated by activities and initiatives, led by FAO in collaboration with Members, partners and key stakeholders, to integrate aquatic foods into global food security and sustainability, enhance policy advocacy, scientific research and capacity building, disseminate sustainable practices and technological innovations, and support community involvement. Part 1 of this edition of The State of World Fisheries and Aquaculture benefits from significant improvements in data collection, analytical and assessment tools and methodologies to present the most up-to-date review of world fisheries and aquaculture production and utilization. Part 2 highlights the role of FAO and its partners to catalyse the transformational changes required to support aquaculture expansion and intensification, effective management of global fisheries and upgrading of aquatic value chains. Part 3 covers the high-impact challenges and opportunities of the untapped potential of utilizing whole fish and by-products to improve food security and nutrition, expounds on the role of aquatic food systems in providing critical climate, biodiversity and environmentally sound solutions, and highlights the importance of their integration into national and multilateral processes. It also presents an outlook on future trends up to 2032 based on projections. The State of World Fisheries and Aquaculture 2024 provides the most up-to-date and evidence-based information, supporting policy, scientific and technical insights on challenges, opportunities and innovations shaping the present and future of the sector, for the benefit of a wide and expanding audience of policymakers, managers, scientists, fishers, farmers, traders, civil society activists and consumers.
