Freshwater infestation by the water hyacinth weed has reached crisis proportions in many areas of Africa and the Middle East. Accumulated environmental, economic, and social damages to date are estimated in the billions of dollars. Most severely affected are riparian communities and those people who depend upon the environmental services or production from affected water bodies. Years of research has produced significant new findings and advances in water hyacinth control and utilization. However, it is all too apparent that this knowledge is not being properly applied to manage the weed.

In recent years, there has been significant progress in biomass research as bio-based products are beneficial to the environment, energy-saving, and cost-saving if they are processed properly. The book collects the most state-of-the-art works related to the natural fiber composites in a Special Issue entitled “Natural Fiber Biocomposites”. These works address all the issues related the manufacturing of natural fiber composite products, from (1) raw materials, such as wood, flax fiber, and cellulose nanofiber; to the (2) raw material treatments, such as furfuryl alcohol pretreatment, ultrasonic vibration treatment (UVT), and extraction method for the resins; to the (3) process of the composites fabrication, such as thermo-hygro-mechanical densification; and to the (4) performance of the composites, including mechanical, moisture absorption, opacity, thermal, and biodegradability. Discussions on the adhesives/resins used in the natural fiber composites fabrication, such as dried distiller’s grains and solubles (DDGS), pennycress (Thlaspi arvense L.) press cakes (PPC), and lesquerella [Lesquerella fendleri (A. Gary) S. Watson] press cake (LPC), starch, and polylactic acid (PLA), are also part of the book. It is believed the technical information presented in this book will contribute to the development of the bio-based composites.

Weed management does not consist solely in the use of herbicides: other methods exist. The paper emphasizes the importance of evaluating weed ecology in understanding weed problems, the need to evaluate seed banks in the soil, the importance of evaluating weed competition and the ability of crops to compete with weeds. Also covered are troublesome weed problems including water hyacinth, and the risks and benefits of using transgenic herbicide-resistant crops.
