2.1 技术简介

技术定义:

Rotational fertilization is an integrated crop-livestock management measure practiced by the agropastoralist Peulh.

2.2 技术的详细说明

说明:

At intervals of 2-3 years the Peulh agropastoralists relocate with their livestock to a new area previously used for crop cultivation - where they install their temporary dwellings and improve soil fertility by applying farmyard manure and other organic materials.

The rotation of temporary habitation areas leads to successive fertilization of the land. Livestock (cattle or small ruminants) are corralled or tethered in the rehabilitation area over-night. They feed on crop residues and emerging grasses after harvesting of the crops. Dung dropped within the coral area is collected and then distributed on the fields. The main criterion for site selection is the level of land degradation. The size of the area occupied is maximum 500 m2, and depends on family size, herd size and on the quantitative and qualitative objectives of soil fertilization of the land owner.

In the years after settlement (after families move to a new location) the treated area is used for crop cultivation, and crop rotation/intercropping are practiced (e.g. millet/ legumes) for increased and diversified production, improved pest control and fertility management.

The effectiveness of this technology has led to field-fertilization contracts between agro-pastoralists and sedentary farmers. The farmers offer post-harvest grazing rights to the agropastoralists who in turn fertilize the land and benefit from the access to the important weekly markets in the area where they can sell milk. In this case the agropastoralist families and their livestock split up after the rainy season: a part assures fertilization of the own land, the other part is in charge of fertilizing foreign land (during 3-4 months) before returning home.

4.8 影响成本的最重要因素

描述影响成本的最决定性因素:

Establishment of housing infrastructure is done collectively, involving dozens of community members within less than a week. Construction material is taken from the woodlands; many parts are re-used after moving. While expenses are expressed in US$, in reality costs are in kind (mutual help) or not paid for (free lumber). Maintenance activities include: maintenance and re-building of dwellings. Costs for crop cultivation (US$ 335-535 annually) are not included.

6.8 技术的弱点/缺点/风险及其克服方法

编制者或其他关键资源人员认为的弱点/缺点/风险	如何克服它们？
Growing costs and decreasing availability of timber and poles for establishment of infrastructure	re-introduce traditional techniques of long-term conservation of housing materials.
High labour input for implementation	reinforce community structures for mutual help.
Area treated by the technology is too small regarding the area in need of treatment (degraded land)	reinforce the solidarity between communities to increase the treated area.
Negative effect on the woodland (brousse tigrée): cutting for building materials, clearing for cultivation	identify new ecological materials for house construction; tree plantation.
Marginalization of families with low activity potential	reinforce mutual help systems to support poor / small families.
