Contribution of the thermal infrared band of Landsat-7 ETM+ in the detection of seawater pollution along the Lebanese shoreline
United Nations Environment Programme

The marine environment in Lebanon has been recently affected by land-derived pollution. This problem mostly concerns areas with dense urban activities. While threatening the marine ecosystem, it also affects, as a consequence, the human populations. Along the225 km shoreline, 75 permanent or temporary watercourses discharge polluted and wastewater into the sea, with also numerous sewage outlets and oil spills. These pollution inputs are categorized under four major classes: 1) wastewater inflows||2) river transported sediments and debris||3) thermal inflows||4) chemical and oily fluids. The true areal extent of these pollutions is not well identified yet, which requests a comprehensive and continuous observation of the coastal waters. The thermal bands of satellite images of Landsat-7 ETM+ can be successfully utilized for this purpose. The principle of this identification relies upon thermal discrimination between seawater and polluted water temperatures. This thermal mapping has identified 49 major sources of pollution in the Lebanese marine environment, the nature of which has been checked in the field. Most of them are related to uncontrolled human activities, such as sewage outfall, refineries and factories. These results should provide decision-makers with a sound base for implementing the necessary mitigation policies.

Africa water Atlas
United Nations Environment Programme

This Atlas is a visual account of Africa's endowment and use of water resources, revealed through 224 maps and 104 satellite images as well as some 500 graphics and hundreds of compelling photos. However the Atlas is more than a collection of static maps and images accompanied by informative facts and figures: its visual elements vividly illustrate a succinct narrative describing and analyzing Africa's water issues and exemplifying them through the judicious use of case studies. It gathers information about water in Africa and its role in the economy and development, health, food security, transboundary cooperation, capacity building and environmental change into one comprehensive and accessible volume. UNEP undertook the production of this Atlas at the request of the African Ministers' Council on Water (AMCOW) and in cooperation with the African Union, European Union, United States State Department, United States Geological Survey and other collaborators.

A practical guide to landfill management in Pacific Island countries and territories: Volume 1 - Inland-based waste disposal (2nd edition)
Secretariat of the Pacific Regional Environment Programme (SPREP)

Solid waste management is an environmental priority for most islands in the Pacific. Unfortunately, lack of recycling and reduction initiatives, poor waste collection systems, open dumpsites, and environmental pollution are still common in many countries in the region. Despite this general outlook, there are a number of positive changes being made to improve waste management policies and practices in Pacific Island Countries and Territories (PICTs), including improvement of collection systems, implementation of container deposit schemes, and the upgrading and construction of sanitary landfills. This book is primarily targeted at solid waste officers in Pacific island countries and territories (PICTs) who may have little background in engineering and construction. The objective of this guide is to help those users understand the concept of a landfill and its operation.

The economics of ecosystems and biodiversity: mainstreaming the economics of nature: A synthesis of the approach, conclusions and recommendations of TEEB
United Nations Environment Programme

The aim of TEEB is to provide a bridge between the multi-disciplinary science of biodiversity and the arena of international and national policy as well as local government and business practices. The scope of TEEB is intentionally broad and it should therefore be seen as an inspiration and as an invitation for others to deepen its findings and to develop more context- specific recommendations. Ideally, TEEB will act as a catalyst to help accelerate the development of a new economy: one in which the values of natural capital, and the ecosystem services which this capital sup- plies, are fully reflected in the mainstream of public and private decision-making.
