编制者和关键资源人员接受有关使用通过WOCAT记录数据的条件。:

2. SLM技术的说明

2.1 技术简介

技术定义:

Carrob tree protection from rat attacks include protection of trees directly by using aluminium layers as rings on the neck of the carob trees in order to keep rats away from climbing on the threes and thus causing problens on fruits and new branches. Furthermore, poisonus rat baits are attached on the trees in case the aluminium layers can not be used.

2.2 技术的详细说明

说明:

Carob trees are attacked every year by rats who nibble the trunk stem of the tree, remove the bark of the trunk and the branches sucking the juice and eat the mature fruits. Rats nibble the bark of the tree in order to reduce their teeth size which tends to enlarge year by year. This results in the death of the tree branch or even of the entire tree. The tree may also show symptoms of hemiplegia. Rats run on the tree through the trunk. Apart from the direct effect of rat attacks on carob trees, rats also cause other problems to humans and animals. Rats are vectors for serious pest and diseases

Purpose of the Technology: The rat population increases rapidly when there is enough food (such as carobs) available, and the population grows even faster in the absence of natural enemies. . Through interrupting the access from the ground to the tree trunk, or by pruning the branches which are connected to the ground, the rats are hindered from climbing the trees. Rats can also be controlled through the use of chemical baits. However, these baits should only be used by experts who know where and how to place them in order to avoid that other animals come in contact with the baits. Natural enemies such as cats, snakes and birds (e.g. Bam owl (Tyto alba)) should be breeded and established on the carob trees, and farmers, hunters and locals should be informed not to kill the natural enemies of rats.

Establishment / maintenance activities and inputs: The carob trees can be protected from rats by covering the tree neck and trunk from the ground up to 1 meter with a hard material such as aluminium with a slippery surface. This way the rats are not able to climb the trees since they will slither on the ring layer.

Natural / human environment: The carob tree protection will increase the production of carobs and therefore the income of the growers. Already established carob trees could provide a good income to growers with low production cost. The population of rats will decrease since the major source of food will not be provided anymore. Educating farmers, hunters and the local population about the benefits of natural enemies will allow that the environment regulates the rat population by itself.

Major land use problems (land users’ perception): Carob growers: Rats are attacking the carob trees causing the death of the trees and damage of fruits.
Locals: The rat population increased during the last 30 years especially in areas where carobs are grown.
Agricultural officer: Rat population increased rapidly causing serious problems in carob production due to heavy rainfall in 2012 and to the hunting and killing of the natural enemies such as snakes and birds by the locals and the farmers.

注释:

Due to the damage caused on the carob trees by rats already, the trees will need some time (2-3 years) to create new branches able to produce fruits. Furthermore no new damages occur on trees.
During the first 3-5 years the aluminium layer can remain on the trees. After this period the aluminium should be replaced with a larger one due to the enlargement of the tree trunk.

10 land user families have adopted the Technology without any external material support

Comments on spontaneous adoption: Due to the lack of effective and cheap ways for controlling rat attack on carob trees the land users are adopting the technology, and so far they get positive results.

There is a little trend towards spontaneous adoption of the Technology

Comments on adoption trend: Few other land user are interested in adopting the technology. Many other land users are not adopting the technology because they inherited the land and they are not actually working on the land in order to make profit.
