تعريف التقنية:

Applying organic residuals on denuded ares

2.2 وصف تفصيلي للتقنية

الوصف:

The concerning rangelands are severely degraded and parts of them have even lost their topsoil layer entirely. Nevertheless, in many cases some remnant vegetation patches are still in place and can serve as seed banks during the restoration process. In order to stabilize the surface (i.e. to reduce the effects of freeze-thaw processes), provide nutrients to the system, increase water availability and facilitate the distribution of native species within the degraded areas, tractors are used to spread manure or hay over the denuded areas. All implementations are based on the methods and tools used in ecological restoration, aiming at re-activating environmental and ecological processes and increasing the resilience of the ecosystems undergoing restoration. Denuded patches, preferably close to the remaining vegetation "islands" are covered with organic matter in order to stabilize the surface, facilitate seed production and seed dispersal and provide safe sites for seed germination.

Purpose of the Technology: The purpose with the technology is to halt further land degradation and facilitate natural succession within the area undergoing restoration. In the long-term, it should substantially reduce wind and water erosion. It should also lead to increased biodiversity, enhanced water availability and accelerated carbon sequestration (in soil and vegetation). The overall restoration task is to increase the resilience of the ecosystems against natural hazards; such as volcanic activities.

Establishment / maintenance activities and inputs: In the year after the areas are treated, they are commonly treated with a low portion of inorganic fertilizer to add easily dissolvable nutrients to the seeds and seedling that have already germinated within the area. The fertilizing treatment is repeated approx biannually for 4-8 years on the average.

Natural / human environment: In the long-term, the technology is expected to substantially increase biomass production, re-build soil qualities, accelerate carbon sequestration and secure water availability within the rangeland and the adjacent ecosystems. The areas still grazed are expected to be more suitable for livestock grazing and the protected areas are expected to be of more recreational and aesthetic value. Increased vegetation cover will reduce and even halt the sand drift that still creates challenges for inhabitants in adjacent villages, on farmsteads and within the summerhouse clusters, scattered around the area. As the degraded rangeland is in the vicinity of an active volcano (Mt Hekla) the technology is also expected to increase ecosystem resilience against natural hazards like ash and pumice drift and reduce potential offsite damages caused by these materials.

التعليقات:

Major land use problems (compiler’s opinion): Vast parts of the area are heavily degraded due to unsustainable land use through the centuries in combination to harsh climate and frequent volcanic eruptions. The major land use problem are related to the fact that the concerned ecosystems collapsed long time ago and despite all restoration efforts implemented within the area for over 100 years, the systems are still highly dysfunctional. Their carrying capacity is limited and even light livestock grazing can keep further vegetation succession down. Passive restoration might take place where the livestock grazing has been excluded but in most cases some technologies are needed to "kickstart" the ecosystem and break their negative resilience against changes.

Major land use problems (land users’ perception): They are fully aware that the ecosystems are in a poor condition and restoration is needed in order to push improvements forward. They acknowledge that grazing of collapsed ecosystems can maintain the dysfunctional of the systems and hinder ecological improvements. Nevertheless, in many cases they believe the harsh climate and volcanic activities are the main contributors to land degradation - that livestock grazing and the grazing carrying capacity of the rangeland are not fundamental issues in this context.
