2.1 技术简介

技术定义:

Graze land forestation with Ceratonia siliqua (carob trees)

2.2 技术的详细说明

说明:

A stand of Ceratonia siliqua (carob trees) is established within an area used for grazing. Tree density is average (6 m grid configuration) and the majority of maintenance input is limited to the first 3 years. Once established, grazing can continue with few limitations. Ceratonia siliqua (carob tree) is very characteristic of the Mediterranean region, thus blending in very well with the local landscape, especially in the rugged agro-pastoral areas of the Mediterranean islands.
After the successful establishment of the plantation, intense irrigation is no longer required and livestock can be allowed in the afforested area which has been upgraded to an improved agro-pastoral or agroforestry land. This improvement facilitates a healthier ecosystem that mitigates land degradation by stabilizing soil, increasing infiltration and organic matter and promoting flora and fauna. In addition to those traits, Ceratonia siliqua is fire resistant and can promote market diversification for the farmer. The main drawback of this technology is the reduction in livestock and other crop production during the first decade of application until trees are mature.

The purpose of this technology is multifold. The primary goal is to increase ecosystem services provided by the treated area, especially for grazing. The farmer takes advantage of the qualities of carob trees for providing:
(a) Fodder to the livestock from the carob pods as well as leaves from cuttings;
(b) Shade to the livestock during the summer months;
(c) Better soil retention, water infiltration etc.
A secondary goal is to increase market diversification with the direct exploitation of carob beans for various products, such as carob honey and carob flour. These products give added value to the land and allow the farmer to increase his income in a more sustainable way.
At the same time much is gained from various other ecosystem services relevant to habitat and supporting services for the fauna of the area, such as birds and honey-bees. The aesthetic value of the landscape which strongly linked with Cretan traditions and pastoralism lifestyle is enhanced. The touristic attraction of the area is greatly improved providing new options for recreational activities and exploitation through actions such as agro-tourism.

Initially, few structural measures are required, mostly related to preparing slopes and soil for sapling planting and establishing irrigation infrastructure. A palisade that will effectively prevent livestock from damaging young trees needs to be maintained during the first 10 years of application of the technology. 2-year-old saplings are planted in a grid configuration with spacing of 6 m and actively managed for at least 3 years. Management includes watering, fertilization and replacement of dead or weak saplings.

The average annual precipitation in the area is 690 mm and the climate is classified as subhumid. Average annual temperature is 17.5 oC with 7 months below 18 but above 5, thus classifying the area as subtropical. In the location where the technology is applied, land is mostly individually owned and distributed among a few families of a community of about 100 inhabitants. Although the financial means of the land user who applies this technology are more or less on par with those of the rest of the community, he has a wider empirical education and relatively higher social status acquired thought his involvement with the commons.
