As more and more individuals have to travel for work, travel and a myriad of other reasons, it has become somewhat of a priority to have the best technological device to help them get from one point to the next. As a result of this GPS Units have become exceedingly important, especially for those who are on the road on a daily or weekly basis. That is why "How To Pick The Perfect Portable GPS Unit" is a must for every consumer. Gone are the days when printed maps are used to find out just which way to go, not to mention that they tend to become outdated pretty quickly as more and more changes are made to the infrastructure. In this day and age electronic devices are needed to help the user to select the fastest route to their destination. They are pretty user friendly and can easily be updated.
Sheep and wheat are the staples of dryland farms in the Mediterranean zone of the Northern hemisphere. The commonly used dryland farming system introduced in the 1950s is proving unsustainable. Erosion has reached a critical level and pastures have all but disappeared. Experts advise more cropping (forage crops for instance) and more fertiliser. Yet intensification of the present system will only hasten erosion. Is there an alternative system that is both environmentally sustainable and within the means of most farmers in the region? Innovative farmers in a similar climate in Australia discovered a sustainable rotation using annual medics as both fertiliser and pasture. Attempts to transfer their knowledge have often foundered. Why is this so? How much do the experts know about this system? This book pulls apart the warp and weft of development on dryland farms to try to find some answers to these questions.
