ArticleJournal articleCommunity-managed forest landscapes of the Chittagong Hill Tracts: a model of a resilient rural livelihood system in Bangladesh
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Village Common Forests (VCFs) of Chittagong Hill Tracts (CHT) in Bangladesh are the community managed landscapes that harbor rare native plant and animal species which profoundly influences local people’s livelihoods. The purpose of the investigation was to examine whether the VCF management system has any potential for maintaining a resilient local livelihood system in the mountainous landscape of CHT. The investigation was conducted in 2016-2018 in 20 VCFs located in remote hill villages that consisted of sample surveys of floral and faunal diversity in the VCFs and questionnaire-based surveys involving respondents from the respective villages to explore the community management practices concerning resources available in the VCFs and the surrounding agricultural and aquatic ecosystems. The communities meticulously maintain harvesting of plant parts and animals considering the seasonality and reproductive potential of the species. They closely monitor their forestry operations in VCFs, for example, through sporadically maintaining old growth trees in their forests, and protecting tree vegetation in peaks and cliffs of hills, bushy plants in the sloping areas, and bamboo clumps in the foothills in order to sustain availability of water in local water bodies. They follow forest management regimes that help maintain a regulated tree harvesting and a sustained flow of organic matter in VCFs in order to maintain soil fertility both in forests and in the surrounding agricultural lands. The villagers observe that agricultural productivity and diversity of crop land races in areas where no community managed forests exist has been declining due to inadequate soil fertility and availability of water. However, communities lack proper knowledge for monitoring events of climate change that affect their landscapes. Resilience of the VCF landscapes that support both livelihood and ecosystem functions could be further improved through sharing of knowledge among the communities.

ArticleJournal articleAllometric equation for estimating tree above ground biomass modified by ecological environmental factors in tropical dipterocarp forests
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Tropical Dipterocarp Forest (DF) plays an important role in mitigating climate change thanks to its carbon sequestration capacity. In order to estimate the CO2 absorption capacity of DF as a basis for the development of forest ecological services, a system of biomass equations is needed; while very few models for estimating biomass in DF have been published and have not yet reflected the impact of ecological environmental factors. The purpose of the study was to validate and select the best model for estimating tree above ground biomass (AGB, kg) in DF under the influence of ecological environmental factors, thereby improving the reliability. Twenty-eight 0.25 ha plots in the Central Highlands and one 1 ha plot in the Southeast ecoregion in Viet Nam were measured. A total of 329 trees were destructively sampled to obtain a dataset of AGB; Methods for developing equations were weighted nonlinear fixed/mixed models with/without random effects fit by Maximum Likelihood; Using K-fold cross validation with K = 10, we compared and selected the best model with and without ecological environmental factors. As a result, separate ecological environmental factors did not affect AGB, while the combination of the factors influences the AGB model through the form: AGB = AVERAGE × MODIFIER, AGB = a × Db ×WDd × exp (e2 × (P - 1502) + e3 × (BA - 12.62)) that was significantly more reliable than a model without these factors involved; where D (cm), WD (g / cm3), P (mm year-1) and BA (m2 ha-1) are the diameter at breast height, wood density, averaged annual rainfall and total basal area of forest stand, respectively.

ArticleJournal articleCommunity forest management and local financing for forest and landscape restoration in Cambodia
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Forest and natural resources are critical to communities in Cambodia, but they are being strongly affected by land encroachment, illegal logging and over-harvesting. Through the support of FAO’s Forest and Landscape Restoration Mechanism (FLRM), and with the local partnership of the Center for People and Forests (RECOFTC), the Phnom Dek Chambok Hos Community Forestry (PDCHCF) committed to restoring the native trees in their designated forestland, protecting biodiversity, increasing forest cover, and preventing land encroachment. The challenge was to achieve these ambitious goals while also generating income for the community and possibly promoting eco- tourism in the long term. Led by Mr. Khea Sochea, who is from the Kouy Indigenous Group, the PDCHCF has developed an innovative restoration management plan paired with a local financing mechanism that provides short-and long-term incentives and credit schemes to engage members for sustainable forest management. The PDCHCF established a tree plantation site that mixes native and fast-growing tree species and dedicated some areas for intercropping within the degraded area. After consulting PDCHCF members, and in compliance with land laws, the PDCHCF Management Committee decided to grant access to two hectares of land for rice cultivation to the five members who are involved in the maintenance of the tree plantation to provide them with an income- generating activity and an incentive to support their restoration efforts. In the medium or long term, PDCHCF members expect to harvest fast-growing trees to generate revenues for community activities and the credit scheme serving as the financial mechanism and incentive scheme to their members.

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. -
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.
