2. SLM方法的描述

2.1 该方法的简要说明

Find carbon optimized land management practices.

2.2 该方法的详细说明

该方法的详细说明:

Aims / objectives: (1) determine the native background stocks of N, P, K, Mg, Ca, and S in soil to a depth of 10 m in the native systems (rain forest and Cerrado).

(2) determine the temporal change in C and nutrient stocks using space-for-time substitution along the pioneer front gradient from central Mato Grosso to south Pará to assess the influence of land use on C and nutrient budgets.

(3) analyze the stocks of bulk C and of C in soil fractions differing in function and turnover to determine the influence of land use and soil management on distribution of SOM into different pools (i.e., analysis of the quantity and quality of C storage in soil).

(4) quantify the C turnover in these fractions by a combination of the stable C isotope and the 14C approaches (i.e., analysis of the sustainability vs. vulnerability of C storage in soil as affected by land use and soil management).

(5) assess the influence of climatic change on these parameters along the climatic gradient from central Mato Grosso to south Pará (i.e., analyze the sustainability vs. vulnerability of C storage in soil as affected by climate change).

(6) parameterize a C and N turnover model (e.g. CANDY, Rühlmann et al. 2006) at plot level and calculate different land-use and climate-change scenarios.


Methods: Analysing carbon stocks – sampling laboratory work (Elementar analyses).
Soil properties of the two most common soil types (texture, bulk density, pH, plant available nutrients, etc.).
Modelling– model the process of carbon storage after land-use change.


Stages of implementation: Transport into meanings – translate scientific results into recommendations for farmes which land-use type is most carbon friendly.

Role of stakeholders: Implementation of land use decision– depending on the soil properties.

2.7 方法的类型

  • 基于项目/方案

2.8 该方法的主要目的/目标

The Approach focused mainly on SLM with other activities (soil organic carbon pools)

Analyze the impact of different land use types on soil organic carbon storage after deforestation.

The SLM Approach addressed the following problems: the meaning of scientific results to farmers – there is no real importancy for them how much carbon is in their soil

The problem is that the whole climate change debate is based on Carbon, however by land use shift from rainforest to pasture or crop fields, soil organic carbon is not the parameter which is the most important, nevertheless is always in the focus if land-use change is discussed.

2.9 推动或妨碍实施本办法所适用的技术的条件

社会/文化/宗教规范和价值观
  • 阻碍

They only do what they know – new ideas are hard to implement.

Treatment through the SLM Approach:

财务资源和服务的可用性/可得性
  • 阻碍

Small farmers have no money to manage their land carbon friendly.

Treatment through the SLM Approach:

法律框架(土地使用权、土地和水使用权)
  • 阻碍

Land titles are not clarified.

Treatment through the SLM Approach:

The existing land ownership, land use rights / water rights greatly hindered the approach implementation If farmers do not own the land by law they will not invest in protecting their land or invest in programs with duration over more than 5 years.

3. 相关利益相关者的参与和角色

  • 国际组织
3.2 当地土地使用者/当地社区参与该方法的不同阶段
当地土地使用者/当地社区的参与 指定参与人员并描述活动
启动/动机 被动 The land users and communities were contacted by the research project.
计划 互动 Active in giving us allowance for our research.
实施 外部支持 Giving us a platform to present our results- communities.
监测/评估 Until now not happening.
Research 被动

3.4 有关SLM技术选择的决策

具体说明谁有权决定选择要实施的技术:
  • 仅限SLM专家
解释:

Decisions on the method of implementing the SLM Technology were made by by SLM specialists alone (top-down)

4. 技术支持、能力建设和知识管理

4.2 咨询服务

土地使用者有权使用咨询服务吗?:

指明是否提供了咨询服务:
  • 在固定中心
说明/注释:

Name of method used for advisory service: Conferences; Key elements: presenting results, transport into meanings, podium discussion

Advisory service is quite adequate to ensure the continuation of land conservation activities; Results are a basis for further discussions of ‘good practice’ management on community level.
