Clay Materials - For the Self-Reliant Potter

This book about clay materials is the second in a series of books addressing practicing potters and trainees in developing countries. The intention of all the books in the series is to help potters to become more self-reliant by providing advice on the optimum use of locally available raw materials and by explaining techniques which will help potters to increase their production and their income.

The process behind the creation of clay and its geology are described as an introduction to prospecting for and mining clay. Different practical methods of preparing clay materials are illustrated with photos of machinery that can be manufactured locally.

An introduction to clay chemistry is followed by instructions on how to develop clay bodies and a chapter on testing clay.

New GATE Product Information Folders

In 1988, GATE issued its first Product Information Folder, entitled Soil Block Presses. This folder proved to be a useful tool for the BASIN (Building Advisory Service and Information Network) technical enquiry service in providing information on the subject. Given the positive response and the need for similar information material on other subject areas, GATE decided to issue four more folders. They are of uniform design, matching the first, and contain

· a basic introduction to the technology

· the types of equipment available on the market

· criteria for selection and purchase of such equipment

· a select bibliography.

The titles of these four new Folders are

1. Soil Preparation Equipment

2. Clay Brick and Tile Moulding Equipment

3. Concrete Block Producing Equipment

4. Fibre Concrete (FCR)/Micro Concrete (MCR) Roofing Equipment.

These new publications will be available towards the end of 1991. For further information please write to

Extension and Vocational Training

The December 1990 issue of AT Source is a special number devoted to extension and vocational training, two major instruments for advancing technological development and emancipation. The articles on agricultural extension are based on the idea that solutions should no longer be provided by extensionists, but should be the outcome of discussion between (women) farmers and extensionists meeting as equal partners.

The section on vocational training examines various aspects of technological tuition: governmental or NGO schools, preparation for the students' entry into employment, the use of training courses being stretched out over a long period, the relative merits of courses in technical schools compared to practical training, etc.

This issue is a variegated mixture of contemplative and comparative articles and case studies. It is rounded off by a list of references and recommended books for further reading.

Vegetable Gardens

The March 1991 issue of AT-Source contains a mini-special on vegetable garden programmes. The following subjects are dealt with: preconditions for vegetable gardening, nutritional advantages of vegetables and fruits, extension, and practical solutions to input problems.

Also in this issue: a mini-special on mobility aids: conditions for success, and information on orthopaedic shoes and how wheelchairs are made. Plus other articles, including one on wooden ox-cart bearings and one on a wind pump.

The magazin is rounded off with a list of references and recommended reading.

Processing of Food Crops

The June issue of AT Source offers an extensive special on the processing and marketing of food crops. Including comments on fermenting foodstuffs and the local production and selling of soymilk.

Experience with workshops where farmers can transform their own products, established among other places in Peru, Haiti and Angola, form the basis of a reflective and a practical article on this subject.

Besides the special you will find articles on: a pneumatic fertilizer-injector for wet rice-lands, womens' initiatives in Mali and Senegal for the development of ecologically sound agricultural methods, and producing ready-made weaning food.

The list of references and recommended literatur links up with the subjects of the articles in this issue.

AT-Source is published in English and French. For a subscription (Dfl 35.00/year, 4 issues), or to order individual issues, write to:

Small-Scale Poultry Production in the Tropics

This is a recently-published addition to AGROMISA's Agrodok series. It is a practical manual for both subsistence and small-scale poultry farmers, focussing on keeping poultry for egg production.

The book begins with a discussion of the choice between layer or dual purpose breeds, pointing out ways of improving local breeds.

It goes on to describe different types of poultry housing, such as mobile chicken-houses, fold-units, houses with runs, with litter, and with slatted floors, and their advantages and disadvantages. The equipment required for indoor poultry farming is also discussed.

The importance of a plentiful supply of fresh, clean water and a well balanced diet for the productivity of layers is stressed. Guidelines are given on preparing one's own chickenfeed in case it is not regularly available on the market.

Some general hints on hygiene are also given. A list of the most common and most serious poultry diseases caused by infection or malnutrition is included.

The publication concludes with a review of hatching and raising chicks, record-keeping, and the major poultry products.

Hatching Eggs by a Hen or in an Incubator

This completely revised edition of Agrodok no. 34 describes the construction and operation of two types of incubator for hatching a maximum of 50 eggs. The first type is heated by electricity (light bulbs), while for the other type an oil or gas lamp is used.

Construction diagrams and operating instructions are given for both types, including how to control temperature and humidity, check the eggs and keep records.

Chapter 7 is a troubleshooting checklist of problems that may arise, their probable causes, and recommended preventive measures.

As the use of an incubator is not always the best solution for small scale poultry farmers, a chapter on natural brooding is also included. The key points to be kept in mind when choosing between natural brooding and hatching eggs in an incubator are discussed in detail.

Natural Veterinary Medicine

The "modern" method of animal husbandry connected with an increase in the performance of the breeds, goes hand in hand with a loss of resistance to ectoparasites and their vector diseases.

Worldwide campaigns were undertaken to eradicate especially the important disease vectors. Inconceivable amounts of synthetic pesticides were sprayed or dusted over large areas or used by farmers in the stables, causing a steadily increasing resistance in ectoparasites.

At the same time injurious consequences for man and the environment became evident.

Besides general biological methods of controlling ectoparasites the author gives an account of research and empirical data involving pesticides and repellents from plants which have been reported in the course of the last few centuries.

The aim is to recall measures and potentials for natural, traditional control of ectoparasites and to give useful suggestions for experimentation in this field.

Especially for small-scale farmers in tropical and subtropical countries, the book hopes to provide stimuli for satisfactory uses of local resources which are reasonably priced in comparison with synthetic pesticides.

The author worked with AGRECOL to compile this resource book.
