Grundlagen zur Bodenfruchtbarkeit - Die Beziehung zum Boden gestalten
Die Broschüre beleuchtet die Bodenfruchtbarkeit aus verschiedenen wissenschaftlichen und bäuerlichen Blickwinkeln. Die Informationen wollen praktische Beobachtungen der Landwirte ergänzen und dazu anregen, die Beziehung zum Boden zu überdenken und eine wirklich nachhaltige Bodenkultur zu praktizieren
Základy půdní úrodnosti
Zvyšování půdní úrodnosti bylo pro průkopníky ekologického zemědělství základem veškerého jejich úsilí. Přesto zachování úrodné půdy mnohdy nebyla věnována dostatečná pozornost. Ekologické zemědělství je však na přirozené půdní úrodnosti závislé.
Oslabená a poškozená půda nám nemůže poskytnout to, co od ní očekáváme. Udržet úrodnost půdy vyžaduje velkou péči. Předkládaná brožura ukazuje půdní úrodnost z různých úhlů pohledu. Naším záměrem však nebylo vytvořit obecně platný „návod k použití“. Informace mají být mnohem spíše podnětem k tomu, aby se o vztahu člověka k půdě smýšlelo jinak a aby se tento vztah utvářel ve prospěch budoucnosti
Assessing the spatio-temporal pattern of winter sports activities to minimize disturbance in capercaillie habitats. eco.mont (Journal on Protected Mountain Areas Research)|eco.mont Vol. 3 No. 2 3 2|
Outdoor activities may have serious consequences for wildlife species that are sensitive to human disturbance. The pressure of outdoor activities on natural landscapes has increased dramatically in recent decades. However, we generally lack information on the spatial and temporal patterns of outdoor activities – a fact that makes it difficult to quantify the impact on wildlife and thus to implement and justify measures to constrain outdoor activities. In the winter seasons 2008 / 2009 and 2009 / 2010, we equipped 303 recreationists in the Val Müstair Biosphere Reserve, eastern Swiss Alps, with GPS loggers to record their spatial and temporal pattern of landscape use. We then analysed how the resulting pattern of spatial use overlapped with the habitat of capercaillie Tetrao urogallus, an endangered woodland grouse species that is highly sensitive to disturbance. For our study we used the official capercaillie core winter habitats observed by the game wardens of the Canton Grisons. The recorded 319 trips of 188 backcountry skiers and snowboarders and 231 trips of 115 snowshoers combined show an inhomogeneous use of subareas in the region. With one exception, the trips are located in the main valley and the adjoining southern and northern slopes and peaks. The trips of snowshoers result in a dispersed use pattern across the main valley, while the trips of the backcountry skiers and snowboarders are concentrated more on official and popular routes. Rarely did recreationists trespass official wildlife sanctuaries or cross capercaillie habitat patches. However, one official, very popular backcountry skiing route crosses one of the largest capercaillie habitats. Here the recorded trips show wide-ranging spatial use with many connectors to the main route. As a consequence, this capercaillie habitat patch is dissected into smaller undisturbed patches. GPS logging in combination with camera trap data provides detailed information on the spatio-temporal land-use pattern of outdoor activities. Based on these data, we identified a conflict of interest in the Val Müstair Biosphere Reserve that has to be resolved by management in a joint participatory process with the main stakeholders. Our methods and results could be transferred to other Alpine regions and be used for any land cover types. In this way we hope to contribute to mitigating conflicts between human outdoor activities and wildlife populations
I Fondamenti della fertilità del terreno
La fertilità del suolo è riconosciuta come valore fondante sin dai pionieri dell'agricoltura biologica ma, ancor oggi, alla conservazione di un suolo fertile non viene attribuita abbastanza attenzione. Eppure l'agricoltura biologica dipende da una buona e naturale fertilità del suolo
