ArticleJournal articleA disjunctive marginal edge of evergreen broad-leaved oak (quercus gilva) in East Asia: the high genetic distinctiveness and unusual diversity of Jeju island populations and insight into a massive, independent postglacial colonization

No results found.Jeju Island is located at a marginal edge of the distributional range of East Asian evergreen broad-leaved forests. The low genetic diversity of such edge populations is predicted to have resulted from genetic drift and reduced gene flow when compared to core populations. To test this hypothesis, we examined the levels of genetic diversity of marginal-edge populations of Quercus gilva, restricted to a few habitats on Jeju Island, and compared them with the southern Kyushu populations. We also evaluated their evolutionary potential and conservation value. The genetic diversity and structure were analyzed using 40 polymorphic microsatellite markers developed in this study. Ecological Niche Modeling (ENM) has been employed to develop our insights, which can be inferred from historical distribution changes. Contrary to our expectations, we detected a similar level of genetic diversity in the Jeju populations, comparable to that of the southern Kyushu populations, which have been regarded as long-term glacial refugia with a high genetic variability of East Asian evergreen trees. We found no signatures of recent bottlenecks in the Jeju populations. The results of STRUCTURE, neighbor-joining phylogeny, and Principal Coordinate Analysis (PCoA) with a significant barrier clearly demonstrated that the Jeju and Kyushu regions are genetically distinct. However, ENM showed that the probability value for the distribution of the trees on Jeju Island during the Last Glacial Maximum (LGM) converge was zero. In consideration of these results, we hypothesize that independent massive postglacial colonization from a separate large genetic source, other than Kyushu, could have led to the current genetic diversity of Jeju Island. Therefore, we suggest that the Jeju populations deserve to be separately managed and designated as a level of management unit (MU). These findings improve our understanding of the paleovegetation of East Asian evergreen forests, and the microevolution of oaks .

ArticleJournal articleThe making of resource frontier spaces in the Congo Basin and Southeast Asia: A critical analysis of narratives, actors and drivers in the scientific literature

No results found.Forest frontiers are rapidly changing to production of commodity agriculture throughout the tropics, with far-reaching transformations in landscapes and livelihoods. Diverse land uses in frontiers – often mixed swidden cultivation systems and forest mosaics under forms of customary tenure –generate multiple ecosystem services, support local societies, and are being lost with increasingly high costs. Many of the dynamics that drive frontier commoditization are well-rehearsed. Policies to deregulate markets, privatize land tenure, improve connectivity and open borders to trade have stimulated resource exploitation. The accompanying territorial interventions such as new enclosures, property regimes and claims are purposefully employed to create space and labor, and have radically reconfigured the relationships of millions of people to land and rule. Within these politico-economic landscapes, local people navigate and execute agency to pursue their own development aspirations. Narratives of what is an opportunity for whom, who should benefit from these spaces, and what is a problem in need for a solution have shaped these policies and practices over time. They are also employed to legitimize development choices in frontiers. Science plays a critical role in these processes, by putting forward (and discarding) particular knowledge and understandings, contributing to problematisations and suggesting new solutions. In this paper, we ask how science has portrayed forest frontiers in the Congo Basin and Southeast Asia over time. Specifically, we analyse the storylines put forward in the scientific literature and how these have contributed to the creation of spaces for resource frontiers of the colonial and post-colonial state. Which actors have what roles in the frontiers, and how are processes of territorialization justified or challenged? This analysis allows for a deeper understanding of how commodification of frontiers came about, and what role science plays within.

ArticleJournal articleDoes independent forest monitoring reduce forest infringement? Insights from Ghana’s collaborative mobile-based IFM system
XV World Forestry Congress, 2-6 May 2022

No results found.Independent Forest Monitoring (IFM) has been a feature of international effort to improve forest governance since its beginning in Cambodia in 1999. Today, IFM has gained traction and is an integral element of emerging forest governance schemes such as voluntary partnership agreement (VPA) which seeks to promote trade in legal timber between EU member countries and timber-producing countries in the global south. Within the VPA, IFM aims to complement the national due diligence mechanisms by flagging illegalities and providing opportunities for redress. Ghana is one such country where IFM is emerging within the country's VPA to address perennial forest governance challenges including corruption. This is often done through projects that develop and train communities on forest laws and provide them with mobile phones and appropriate software applications to monitor and flagged illegalities within their localities. Although this has been done over the years little insights are available on how this IFM architecture has performed. Such analysis is required to understand if IFM presents any hope for sanitizing the forest sector. On the back of this, this paper review community IFM monitoring reports identify key trends on forest illegalities and how they were addressed or otherwise. We found that the real-time monitoring platform has generated 747 alerts as of December 2019. Nearly 72% of them have been verified with most Social Responsibility Agreement (SRA) related infractions resulting in some 32 communities receiving SRA for the first time or on a continuous basis. The study concludes that communities are now protecting their forest as a result of compliance from timber companies which has generated revenue in the form of social responsibility agreements for community projects. Managers of the forest reserves are now responsive to queries as a result of the digital nature of the alerts.

BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also available in:
No results found.The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018. -

Major transformations in agricultural systems, rural economies, and natural resources management are necessary. The present study was undertaken for the quadrennial review of FAO’s strategic framework and for the preparation of the Organization Medium-Term plan 2018-2021. -
Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms.
