Within the framework of a Technical Assistance (TA) Agreement (UTF/NIR/066/NIR), the Food and Agriculture Organization of the United Nations (FAO), provided technical support to the Federal Government of Nigeria to undertake a number of activities, which included land use/land cover analysis and production of an updated land cover/land use map for Nigeria. An existing national classification system, adopted by FORMECU in 1998, and comprising 36 classes was aggregated into 12 classes and used for this purpose. A land use/land cover map for 1995 based on the 12 classes was also produced. The land use/land cover analysis were undertaken in SEPAL and SEPAL-CEO (SEPAL-Collect Earth Online) which is an open-source, cloud-based platform. Map mosaics for 2006 and 2016 were produced from free Landsat images extracted from the SEPAL archives and classification was then undertaken to Collect Earth Online using the 12 aggregated land use/land cover classes. The procedure required the use of higher resolution images such as SPOT 5, GeoEye, and IKONOS images. A total of 1667 training data points were collected across the 12 land cover classes over the entire country. Fieldwork (ground-truthing) was carried out in six states to verify and clarify unresolved areas especially among savannas and arable land, tree crop plantation and forest plantation, freshwater forest and mangrove; and led to the collection of 252 additional training data points.

This manual was designed to introduce users to the procedures for navigating SEPAL and Collect Earth Online Software in order to prepare land use/land cover mapping. The illustrations and examples are tailored to mapping Nigeria’s land cover. SEPAL is a free open source package which offers great potential to developing countries with limited access to multi-date images and limited computing resources for image processing and analyses.

This book presents recent estimates on the rate of change of major land classes. Aggregated globally, multiple impacts of local land changes are shown to significantly affect central aspects of Earth System functioning. The book offers innovative developments and applications in the fields of modeling and scenario construction. Conclusions are also drawn about the most pressing implications for the design of appropriate intervention policies.

Climate resilience, or the capacity of socio-ecological systems to adapt and upkeep their functions when facing physical-chemical stress, is a key feature of ecosystems and communities. As the risks and impacts of climate change become more intense and more visible, there is a need to foster a broader understanding of both the impacts of these disruptions to food, water, and energy supplies and to increase resilience at the national and local level. The Handbook of Climate Change Resilience comprises a diverse body of knowledge, united in the objective of building climate resilience in both the industralised and the developing world. This unique publication will assist scientists, decision-makers and community members to take action to make countries, regions and cities more resilient.

This is the 7th edition of the FAO's biennial report on the state of global forest resources, recent developments and emerging issues in the forest sector. This edition focuses on progress towards sustainable forest management at the regional and global levels, with each regional report structured according to seven thematic elements: the extent of forest resources; biological diversity; forest health and vitality; productive functions of forest resources; protective functions of forest resources; socio-economic functions; and legal, policy and institutional frameworks. These summaries are based on the most current information available, including new data from the Global Forest Resources Assessment 2005 (FRA 2005). The report goes on to consider 18 key issues in the forest sector, including: climate change, forest landscape restoration, forest tenure, invasive species, wildlife management and wood energy. The overall conclusion is that whilst progress is being made, it is very uneven with those regions with developing economies and tropical ecosystems continuing to lose forest area whilst lacking adequate institutions to reverse this trend. The biggest limitation for evaluating progress is weak data, with many countries lacking the financial resources to undertake national forest assessments.

This is the sixth edition of the biennial report on the current state of global forest resources and recent developments and emerging issues in the forest sector. It includes contributions from key non-governmental organisations and from individuals, as well as articles written by FAO staff. This edition focuses on options for sustainable forestry management to maximise the sector's economic viability, and issues discussed include forest resources, conservation aspects, institutional issues and legal frameworks, international policy developments, the economic benefits of agroforestry, wood energy production, import tariffs and non-tariff measures, and the impact of violent conflicts on forest resources.
