Advances in close-range and remote sensing technologies are driving innovations in forest resource assessments and monitoring on varying scales. Data acquired with airborne and spaceborne platforms provide high(er) spatial resolution, more frequent coverage, and more spectral information. Recent developments in ground-based sensors have advanced 3D measurements, low-cost permanent systems, and community-based monitoring of forests. The UNFCCC REDD+ mechanism has advanced the remote sensing community and the development of forest geospatial products that can be used by countries for the international reporting and national forest monitoring. However, an urgent need remains to better understan...
Globally, the number of conflicts is increasing which is the main cause of much of the recent deterioration of the global food security situation. This situation is exacerbated by climate related shocks. Since 2009, a combination of man-made and natural disasters has disrupted livelihoods, threatened food security and forcibly displaced millions of people in northeast Nigeria. The conflict, in northeast Nigeria, takes on a central role in the ongoing food crisis by severely curtailing the ability of populations to access land and other natural resources such as woodfuel, the central object of this analysis. Access to energy is a precondition to food security, both are often highly constraine...
This report provides an update on Reducing Emissions from Deforestation and Degradation Plus1 (REDD+) forest reference (emission) levels (FREL/FRLs) and REDD+ results submitted to the United Nations Framework Convention on Climate Change (UNFCCC), and relevant developments under the Green Climate Fund concerningREDD+ results-based payments. It illustrates the choices countries have made when constructing their FREL/FRLs and areas for improvement identified during technical assessments. Such information can help countries to learn from each other.
Land cover assessment and monitoring of its dynamics are essential requirements for the sustainable management of natural resources, environmental protection, food security, humanitarian programmes as well as core data for monitoring and modelling. Land Cover (LC) data are therefore fundamental in fulfilling the mandates of many United Nations (UN), international and national institutions and programmes. Despite the recognition of such importance, current users of LC data still lack access to sufficient reliable or comparable baseline LC data. These data are essential to tackle the increasing concerns in regard to food security, environmental degradation, and climate change. Critically, maintaining and restoring land resources plays a vital task in tackling climate change, securing biodiversity, and maintaining crucial ecosystem services, while ensuring resilient livelihoods and food security.
The Food and Agriculture Organization of the United Nations (FAO) has been providing support to member countries on national forest monitoring for decades. Best practices and lessons learned from this support are summarized in FAO´s Voluntary guidelines on national forest monitoring (VGNFM). The guidelines provide principles, elements and best practices for the establishment and implementation of a multipurpose National Forest Monitoring System (NFMS). The aim of this paper is to strengthen the elements and guidelines provided in the VGNFM in the context of Reducing Emissions from Deforestation and Forest Degradation (REDD+). It also includes a deeper analysis of the United Nations Framework Convention on Climate Change decisions and the most recent methodological recommendations provided by the Intergovernmental Panel on Climate Change, focusing on the three pillars of an NFMS for REDD+: a Satellite Land Monitoring System, a National Forest Inventory, and REDD+ reporting, including the combination of remote-sensing and ground-based forest inventory to estimate anthropogenic forest related Greenhouse Gas emissions by sources and removals by sinks.
For years scientists viewed the deep sea as calm, quiet, and undisturbed, with marine species existing in an ecologically stable and uniform environment. Recent discoveries have completely transformed that understanding and the deep sea is recognized as a complicated and dynamic environment with a rich diversity of marine species. Carefully designe
The development of effective methodologies for the analysis of multi-temporal data is one of the most important and challenging issues that the remote sensing community will face in the next few years. The importance and timeliness of this issue are directly related to the ever-increasing quantity of multi-temporal data provided by the numerous remote sensing satellites that orbit our planet. The synergistic use of multi-temporal remote sensing data and advanced analysis methodologies results in the possibility of solving complex problems related to the monitoring of the Earth's surface and atmosphere. This book brings together the methodological aspects of multi-temporal remote sensing image analysis, real applications and end-user requirements, presenting the state of the art in this field and contributing to the definition of common research priorities. Researchers and graduate students in the fields of environmental monitoring, remote sensing image analysis and pattern recognition will appreciate the interdisciplinary approach thanks to the articles written by experts from different scientific communities.
This report presents a cost–benefit analysis of three forestry interventions aimed at producing a sustainable supply of woodfuel and reducing land degradation and deforestation in the vicinity of three refugee camps (Mtendeli, Nduta and Nyarugusu) in the Kigoma region, United Republic of Tanzania. The proposed forestry interventions are: forest rehabilitation; wood-energy plantations; and agroforestry.
To coincide with the 50th anniversary of FAO’s Committee on Forestry, this edition of Unasylva showcases ways in which forests are delivering the "four betters" and underscores how forests are crucial for resilient and sustainable agrifood systems in a changing climate. As FAO’s longest running periodical, Unasylva focuses on issues and themes relevant to forestry and forest industries and aims to bring globally significant developments in forestry to policy-makers, forest managers, technicians, researchers, students and teachers around the globe.
National information needs on forests have grown considerably in recent years, evolving from forest area and growing stock information to key aspects of sustainable forest management, such as the role of forests in the conservation of biodiversity and the provision of other ecosystem services. More recently, information on changes in carbon stocks, socio-economic aspects including the contribution to livelihoods and poverty reduction, governance and broader land use issues has become critical for national planning.
