Das Ergebnis: In nur sechs Jahrzehnten wurde fast ein Drittel der globalen Landfläche auf irgendeine Weise verändert. Der Wert war damit nach Angaben aus Karlsruhe etwa vier Mal so hoch, wie langfristige Analysen bis dahin angenommen hatten

Zwischen 1963 und 2005 nahm die weltweite Anbaufläche für Nahrungsmittel um etwa 270 Millionen Hektar zu. Das entspricht etwa acht Mal der Fläche Deutschlands.

In summary, public and private rangeland resources provide a wide variety of EGS. Additionally,spiritual values are vital to the well-being of ranching operations, surrounding communities, and the nation as a whole. Society is placing multiple demands on the nation’s natural resources,and it is extremely important that NRCS be able to provide resource data and technical assistance at local and national levels. (4) Rangelands are in constant jeopardy, either from misuse or conversion to other uses. Holechek et al. (2004) andHolechek (2013) states that in the next 100 years, up to 40percentof U.S. rangelands could be converted and lost to other uses. Land-use shifts from grazing use to urbanization will be much greater in areas of more rapid population increases and associated appreciating land values. Projections supporting forage demand suggestthat changes in land use will decrease the amount of land available for grazing to a greater extent in the Pacific Coast and Rocky Mountains,compared to the North or South Assessment Regions (Mitchell 2000).(5) As society attempts to satisfy multiple demands with limited resources, many ranching and farming operations seek to expand operations for multiple goods and services beyond traditional cattle production. Some diversifiedenterprises may include the following: (i) Management to enhance wildlife abundance and diversityfor fishing, hunting and non-hunting activities(ii) Maintaining habitat for rare plants(iii) Accommodatingnature enthusiasts, bird watchers, and amateur botanists. (6) Planning, evaluation, and communication are necessary steps (consult conservation planning steps) prior to initiating any new rangeland EGS-based enterprises.

Jake Fiennes, the head of conservation at the Holkham estate in Norfolk and author of nature-friendly farming book Land Healer, said he was unsurprised by the results of the report

10-year project by the UK Centre for Ecology and Hydrology revealed that nature-friendly farming methods boost biodiversity without reducing average yield

The negative indirect effects of additional land-use change may outweigh the positive direct effects on global climate and biodiversity, so that a large-scale switch to organic farming in the EU could possibly turn out to be a disservice to global sustainability.

organic farming often requires more land than conventional farming for the same quantity of food output.

The study, published in Nature Food, presents EDGAR-FOOD – the first database to break down emissions from each stage of the food chain for every year from 1990 to 2015. The database also unpacks emissions by sector, greenhouse gas and country. 

Strictly speaking, this is true. No jurisdiction can be legally compelled to designate a Priority Development Area. The region’s 191 PDAs were all nominated by local jurisdictions. San Francisco’s PDAs were unanimously approved by the Board of Supervisors in 2007.
