MeetingMeeting documentMaldives skipjack pole and line fishery catch rate standardization 2004-2011: reconstructing historic CPUE till 1985 2013

No results found.A qualitative description and GLM-based standardization of the Maldivian skipjack (Katsuwo pelamis, SKJ) pole and line fishery catch rate data are presented for the period 2004-2011. The raw data consists of around 124000 records of catch (numbers) and effort (fishing days) by month, atoll and vessel; vessel characteristics were added to the CPUE dataset based on information from the registry of vessels. A subset of 56,698 records were extracted from the dataset, identified as records of fishing activity targeting skipjack. In the process, the paper discusses several data quality issues with the CPUE dataset, notably records with zero skipjack catch with a directed PL fishery and which were eventually discounted from the fil alysis. FAD data was also incorporated into the alysis using the number of active FADS associated with the nearest atoll that the landing data is collected from. In order to do this, the distribution of FADs was split into three regions incorporating the North Atol ls, Middle Atoll and South Atolls. Vessel specific data including hull-type effects, length of the boat (as a vessel size class) and horse power was also used in the alysis. GLM based models using a log response on CPUE were examined. The fil model presented estimated log(CPUE) from independent variables Year, Month, Area (N, S, or M), number of FADs used in the area, and Length of vessel, and interaction effects between the last 3 categories. The data was alysed at a monthly resolution before b eing was collapsed into quarterly sigls for 2004-2011. Filly, using vessel length as a continuous covariate, the CPUE data was estimated for historic periods till 1985.

Unasylva No. 252 - Vol. 71 2020/1
2020This Unasylva issue aims at showcasing forest and landscape restoration (FLR) opportunities and recent developments that have the power to upscale restoration, in order to achieving the Bonn Challenge pledge and other national and international commitments (Sustainable Development Goals (SDGs), the Convention for Biological Diversity (CBD) Post-2020 Agenda, the United Nations Convention to Combat Desertification (UNCCD) Land Degradation Neutrality, Paris Agreement under the United Nations Framework Convention on Climate Change (UNFCCC)) and addressing the needs of the UN Decade 2021-2030 on Ecosystem Restoration. The content adresses thematics of relevance to various audiences: i) flagship restoration initiatives that differ from the so-called “business-as-usual” as they channel more funds, better empower local stakeholders and provide enhanced technical assistance through partners’ coalitions; ii) technical advances that can spread FLR and have a huge potential to be mainstreamed for different reasons (low cost, adaptability, relevance to many ecosystems and contexts, ease of implementation…); iii) the enabling factors for restoration, i.e. coordination, policy environment, resources, knowledge and capacities, as these are the enabling conditions for action to take place on the ground. -
Book (stand-alone)Technical bookCrops and climate change impact briefs
Climate-smart agriculture for more sustainable, resilient, and equitable food systems
2022Also available in:
This series of technical briefs aims to provide a solid knowledge base for building or strengthening stakeholder capacities on climate-smart agriculture (CSA) and applying CSA practices to five crops that are critical to the global agri-food sector: coffee, cowpea, maize, rice and wheat. These briefing notes reflect the growing recognition of the need to share knowledge, best practices, lessons learned and experiences on CSA. They are intended to support stakeholders to make the transition to more sustainable and resilient crop production systems and, thereby reach targets laid out in the Sustainable Development Goals. It is our intent to reach a broad range of stakeholders with this knowledge, especially as we begin a new era of global dialogue on how to transform our food systems. -
Book (stand-alone)High-profileState of knowledge of soil biodiversity - Status, challenges and potentialities
Report 2020
2020Also available in:
No results found.There is increasing attention to the importance of biodiversity for food security and nutrition, especially above-ground biodiversity such as plants and animals. However, less attention is being paid to the biodiversity beneath our feet, soil biodiversity, which drives many processes that produce food or purify soil and water. This report is the result of an inclusive process involving more than 300 scientists from around the world under the auspices of the FAO’s Global Soil Partnership and its Intergovernmental Technical Panel on Soils, the Convention on Biological Diversity, the Global Soil Biodiversity Initiative, and the European Commission. It presents concisely the state of knowledge on soil biodiversity, the threats to it, and the solutions that soil biodiversity can provide to problems in different fields. It also represents a valuable contribution to raising awareness of the importance of soil biodiversity and highlighting its role in finding solutions to today's global threats.
