INTRODUCTION: FORESTS, TREES, WOODFUEL AND FOOD SECURITY Forests cover one-third of the Earth’s land Forests and trees outside forests, surface. It is estimated that over one-third including tree-based agricultural systems, of the world’s population depends on forest contribute to the four dimensions of food goods and services for the direct provision security (Box 1) in multiple ways (Table 1). of food, woodfuel, building materials, Food from forests and trees (fruits, medicines, employment and cash income. vegetables, nuts, mushrooms, fodder and Box 1 Definitions and key terms Food security is a state where all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. Nutrition security is integral to the concept of food security (FAO, 2011a). The four pillars of food security are availability, access, utilization and stability. Availability is achieved if there is adequate food ready for people’s needs. Access is ensured when all households and all individuals within those households have sufficient resources to obtain appropriate foods (through production, purchase or donation) for a nutritious diet. Adequate utilization refers to the ability of the human body to ingest and metabolize food. Stability refers to the temporal determinant of food and nutritional security and affects availability, access and utilization. Chronic food and nutrition insecurity (the inability to meet food needs on an ongoing basis) is distinguished from transitory food and nutrition insecurity (e.g. due to natural and human-made disasters) (Gross et al., 2000). Woodfuel is defined as all types of fuels originating directly or indirectly from woody biomass. The main types of woodfuel in less-developed regions of the world are fuelwood and charcoal. Fuelwood is woodfuel in which the original composition of the wood is preserved; it includes wood in its natural state and residues from wood-processing industries. Charcoal is the solid residue derived from the carbonization, distillation, pyrolysis and torrefaction of wood (FAO, 2004). Forest is defined as land spanning more than 0.5 ha with trees higher than 5 m and a canopy cover of more than 10 percent, or trees able to reach these thresholds in situ. It does not include land that is predominantly under agricultural or urban land use (FAO, 2015). Deforestation is defined as the conversion of forest to other land use or the permanent reduction of the tree canopy cover below the minimum 10 percent threshold (FAO, 2015). Forest degradation is the reduction of the capacity of a forest to provide goods and services (FAO, 2015). Tree-based agricultural systems (also known as agroforestry systems) are defined by tree cover on agricultural land of more than 10 percent. They can include trees on farms, home gardens, intercropping, fallows, woodlots and plantations (Zomer et al., 2014). 1 Table 1.

A strict distinction between these materials is not always possible, and also a generally accepted terminology is lacking. However, research on both materials is increasingly overlapping: sorption and remediation are the domain of activated carbon, which nowadays is also addressed by studies on biochar. Thus, awareness of both fields of research and knowledge about the distinction of biochar and activated carbon is necessary for designing novel research on pyrogenic carbonaceous materials. Here, we describe the dividing ranges and common grounds of biochar, activated carbon and other pyrogenic carbonaceous materials such as charcoal based on their history, definition and production technologies.

  • Tree Care Handbook
    Minnesota SWCD Forestry Association Tree Handbook Dear Tree Planter. With headlines reporting the continuing deforestation of the tropical rain forest, one may ask the question: Are America’s forests in danger of disappearing? Because people such as yourself practice reforestation, our forested acres are actually growing in size. About one-third of the United States, or 731 million acres is covered with trees. That’s about 70 percent of the forest that existed when Columbus discovered America. Almost one third of this is set aside in permanent parks and wilderness areas. Minnesotans’ have planted an average of 12 million trees annually; enough trees to cover over 15,000 acres per year. Good land stewards are planting trees for many good reasons. The results of their efforts can be seen in reduced soil erosion, improved air and water quality, healthy forest industries, enhanced wildlife habitat and generally a more attractive surrounding for us to live in. Aspen has become the most prominent tree in Minnesota’s forests. After clearcutting, aspen regenerates readily by sprouting from its root system or by drifting seeds onto disturbed sites. Most of the other major species in Minnesota need some help from tree planters to ensure that they make up a part of the new forest. The following pages will help explain how to plant and care for a tree seedling. There is a section on the general characteristics and planting requirements of the tree and shrub species commonly planted for conservation purposes in Minnesota. The professionals working in conservation throughout Minnesota thank you for planting, nurturing and wisely using one of Minnesota’s greatest treasures its renewable trees.

  • Sustainability Report for Georgia's Forests
    Executive Summary Georgia’s forests are being sustainably managed to meet the numerous needs of our state today. To ensure our forests will continue to meet the needs of present generations and the projected demands for future generations, many challenges must be addressed. Forest sustainability is dependent on both environmental and economic sustainability. A challenge to either element is a challenge to both elements. Success will depend on proactive decisions by our state leaders and the entire forestry and conservation communities addressing a myriad of forestry-related issues. Georgia boasts more than 24 million acres of forestland. Georgia’s forest inventory volumes are at an all-time high. We have 49 percent more cubic feet of wood growing in Georgia than we did 40 years ago. However, the state’s population is increasing at a record rate. Urbanization continues to be a threat to forest sustainability. Further, recent increases in population and changing land-use patterns have made ongoing forest management more difficult in some areas of the state. These and other trends threaten forest sustainability and the numerous economic, environmental, and social benefits that our forests provide. This report describes both forestland (all forests including those not available for commercial harvest – 24.6 million acres) and timberland (all forests that are available for commercial harvest – 23.9 million acres). (GFC 2016) Georgia’s forest area has remained stable over the past 50 years at about 24 million acres. Approximately 91 percent of this acreage is privately owned, giving Georgia more privately-owned acres of timberland than any other state in the nation.

    Wisdom in the Woods CFWO proposing a new national tree­planting program Canada's woodlot organizations see important role in meeting climate change goals By Bob Austman, Manitoba Dirctor Canadian Federation of Woodlot Owners The new federal environment department, known as Environment and Climate Change Canada, is actively seeking proposals from Canadians on how to help in the fight against climate change. In response, the Canadian Federation of Woodlot Owners is proposing a common sense approach—get out there and plant more trees! The national tree­planting proposal, which will have been submitted by the end of June, will involve a Canada­wide approach. Since each province’s forest resources differ in species composition and distribution, the proposal will recommend a variety of strategies.

Merr.] caused by Macrophomina phaseolina is a disease of economic significance throughout the world. The effects of potassium (K) and phosphorus (P) fertilizer on disease development are unknown. Therefore, two separate trials were conducted in the field during 2008, 2009 and 2010 at Jackson and Milan, TN, USA to evaluate the effects of K and P on severity of −1 −1 charcoal rot. Rates of K (0, 45, 90, 134 and 179 kg K2Oha ) and P (0, 22, 45, 67 and 90 kg P2O5 ha ) were used, with a sixth rate ranging from 0–22 for P and 0–37 for K equal to the recommended K or P fertilizer application based on annual soil testing. The colony forming units of M. phaseolina in soil indicated no significant response for any P treatments in five of six location-by-year and for K applications in all six location-by-year environments.
