2.1 技术简介

技术定义:

Digging trenches on a gentle slope in banana plantation in Rwerazi.

2.2 技术的详细说明

说明:

Trenches dug at 2 ft. wide and 20m long in a banana plantation . Twelve trenches at a distance of 10m each in about 7 acres to control water runoff and soil erosion.

Purpose of the Technology: Trenches to contain and collect heavy water runoff. To reduce loss of top soil and increase soil fertility for perennial crops, thus increasing productivity.

Establishment / maintenance activities and inputs: Kagera TAMP initiative for the use of trenches by land users of Rwerazi matoke association , with hoes, spades, pangas digging trenches of 2ft deep , 2.5 ft wide and 20m long at a space of 10m in a banana planation.

The trenches are of 2 types, Fanya juu and Fanya kin.

Natural / human environment: The area is gentle sloping susceptible to water runoff leading to enough loam sopils in in good banana planation.

3.1 该技术的主要目的

• 减少、预防、恢复土地退化

3.2 应用该技术的当前土地利用类型

农田

• 一年一作
• 多年一作（非木材）

多年生（非木质）作物 - 指定作物:

• 香蕉/芭蕉/蕉麻

每年的生长季节数:

• 2

具体说明:

Longest growing period in days: 150 Longest growing period from month to month: September to December.Second longest growing period in days: 90 Second longest growing period from month to month: March to May.

注释:

Major land use problems (compiler’s opinion): Increased runoff and lack of soil and water conservation would lead to loss of productive top soil, desertification leading to soil infertility and climatic change.

Type of cropping system and major crops comments: Technology is effective in banana plantation.

3.4 供水

该技术所应用土地的供水:

• 雨养

3.5 该技术所属的SLM组

• 横坡措施

3.6 包含该技术的可持续土地管理措施

结构措施

• S3：分级沟渠、渠道、水道
• S4：平沟、坑

注释:

Main measures: structural measures

3.7 该技术强调的主要土地退化类型

土壤水蚀

• Wt：表土流失/地表侵蚀

化学性土壤退化

• Cn：肥力下降和有机质含量下降（非侵蚀所致）

水质恶化

• Ha：干旱化

注释:

Main type of degradation addressed: Wt: loss of topsoil / surface erosion

Secondary types of degradation addressed: Cn: fertility decline and reduced organic matter content, Ha: aridification

Main causes of degradation: soil management (To prevent degradation of land & water banana planation.)

3.8 防止、减少或恢复土地退化

具体数量名该技术与土地退化有关的目标:

4.3 技术建立活动

4.4 技术建立所需要的费用和投入

注释:

Duration of establishment phase: 1 month(s)

4.5 维护/经常性活动

注释:

The land user does not meet the maintenance costs of old existing trenches but establishes /digs new trenches after every 2 years when the old trenches are filled with silt. He believes that old filled trenches should not be worked upon as they are filled with manure and nutrients. By digging new trenches ,the land user meets the new establishment and construction costs.

4.6 维护/经常性活动所需要的费用和投入（每年）

注释:

Machinery/ tools: Hoes,spades, pick axe are used to construct and maintain the trenches.

The costs are the total costs for construction and maintenance of the technology for each land user for area of about 1 ha and were estimated as of 19/04/2013.

4.7 影响成本的最重要因素

描述影响成本的最决定性因素:

-Human labor is scarce.
-High cost of labor.
-Land users require constant monitoring & mobilization.
