Agroforestry, silvo-pastoralism, and agro-silvo-pastoralism are seen and promoted as means to increase food production while simultaneously providing valuable ecosystem services. It is claimed that such systems halt and even revert widespread land degradation, improve and diversify the range of farm products, and safeguard local and regional biodiversity. Brazil in its turn has pioneered some important agricultural technologies in the world, as the no-tillage system, which allows two harvests a year in many parts of the country. Intending to contribute with information regarding such integrated systems, a publication was produced by the Brazilian Agricultural Research Corporation – Embrapa. Titled “Integrated Crop-Livestock-Forestry Systems” it is a richly illustrated, 282 page book, with 20 chapters involving many scientists from different institutions, approaching the major themes related to the subject, addressing technologies available and their potential for further improvement and expansion. Brazilian integrated systems are somehow unique in the way they operate, especially regarding component's rotation time and investments payback capability. They have been showing to be a great alternative for soils recuperation/improvement in transition areas not apt for regular cash crops, but too expensive for simple extensive cattle systems. One of the important features is to provide revenues diversification, thus helping to stabilise farmer's finances.
