Abstract

Sound pesticides management and Integrated Pest Management (IPM) in particular are widely acknowledged as important mechanisms to mitigate pre- and post-harvest losses and to achieve sustainable agricultural intensification. The recent proliferation of agricultural concessions, contract farming arrangements, subsidies and other mechanisms in the country to stimulate production also mean a facilitated access to inputs that must be regulated. Preserving Lao PDR's rich biodiversity is not only a conservation goal in itself but also contributes to food security, poverty reduction and development. Sound pesticides management contributes to agricultural competitiveness and trade. Trade in agricultural products, and in particular market access, is affected by the presence of pests in a traded consignment or the presence of excessive pesticide residues in food products that attract the application of sanitary and phytosanitary (SPS) measures by trading partners. The Lao PDR Government has made strides in controlling banned, unregistered and illegally imported pesticides in the last ten years.

Abstract

Given that the threat of water shortage is expanding across the globe, the evolution of advanced technologies that enable water purification and, thus, water re-use in an energy and resource efficient manner are of great importance. In this regard, nanomaterials have been playing a crucial role and offering new opportunities for the construction of permeable and selective membranes and adsorbents. Such features are of paramount importance, particularly given the limited available energy resources. In this book, several recent studies are introduced that deal with water treatment via nanomaterial-based technologies. Such state-of-the-art technologies have employed nanomaterials that are made of polymer, composite, ceramic, and carbon, etc., and are shaped in various dimensionalities and forms such as particle (0D), fiber (1D), and film (2D–3D). The nanostructured membranes and adsorbents as well as photocatalytic nanosystems capable of active photodecomposition of organic pollutants, e.g., dyes, are the main focal points of discussion.

Abstract

Water pollution from biorefractory pollutants and emerging contaminants is still a very relevant problem worldwide. Examples of these pollutants include disinfection by-products, pharmaceutical and personal care products, persistent organic chemicals, as well as their degradation products. The occurrence of these contaminants in water has raised increasing concern due to their accumulation and persistence in the environment and the threat they pose to the ecological system and human health. In this Special Issue, papers regarding the advancements in materials and processes for use in the electro- and photoelectrochemical removal of different pollutants from water are collected. The synthesis, characterization and application of materials for use in electrochemical or photoelectrochemical techniques are presented, as well as studies concerning catalytic processes and reaction kinetics.
