Excerpt from Useful Knowledge, or a Familiar Account of the Various Productions of Nature, Mineral, Vegetable, and Animal, Which Are Chiefly Employed for the Use of Man, Vol. 1 of 3: Illustrated With Numerous Figures, and Intended as a Work Both of Instruction and Reference; Minerals The first layer is frequently a rich, black mould, formed almost wholly of animal and vegetable remains. This yields sustenance to the vegetable productions; and thereby becomes the actual, though not the imme diate, support of the whole animal creation. - Beneath this is Often found a thick bed of clay, that furnishes to man a substance of which to make bricks, tiles, various kinds of pottery, and innumerable other articles for the comfort of social life - Next are deposited vast beds of gravel, that are of use in numerous points of view. Underneath this are the infinitely varying strata of sand-1 stone, limestone, &c. Which not only serve for the con struction of buildings, and for other important purposes, but also frequently surround mines which contain the valuable metals.-beneath a slaty stratum are usually discovered those immense beds of coal so requisite for the comfort, and, in some situations, even for the exist ence of man. These strata, it is true, are not always found together, nor are they always discovered in the same Order; but the statement will suffice to show the general nature of their arrangement.

This publication capitalizes on the experience of scientists from the North Africa and Near East countries, in collaboration with experts from around the world, specialized in the different aspects of greenhouse crop production. It provides a comprehensive description and assessment of the greenhouse production practices in use in Mediterranean climate areas that have helped diversify vegetable production and increase productivity. The publication is also meant to be used as a reference and tool for trainers and growers as well as other actors in the greenhouse vegetables value chain in this region.

Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
