2.1 Short description of the Technology

Definition of the Technology:

FMNR is the systematic regeneration of living and sprouting stumps of indigenous vegetation which used to be slashed and burned in traditional field preparation.

2.2 Detailed description of the Technology

Description:

The naturally occurring seedlings and/or sprouts are managed and protected by local farmers. Most suitable are species with deep roots that do not compete with crops and have good growth performance even during poor rainy seasons. In the case study area the three most valuable species – as perceived by land users – are Faidherbia albida; Piliostigma reticulatum and Guiera senegalensis.

Purpose of the Technology: This option allows idle land to become a productive resource during an otherwise unproductive eight-month dry season.

Establishment / maintenance activities and inputs: The ideal density, when grown with cereal crops, is between 50 and 100 trees per hectare. For each stump, the tallest and straightest stems are selected and side branches removed to roughly half of the stem height. Excess shoots are then removed. Regular pruning of any unwanted new stems and side branches stimulates growth rates. Farmers are encouraged to leave 5 stems / shoots per tree, cutting one stem each year and letting another grow in its place. On removing a shoot, the cut leaves are left on the surface where they reduce erosion and are then eaten by termites, returning the nutrients to the soil. The remaining shoots continue to grow, providing a continuous supply of wood. From the first year, firewood is collected from trimmings. From the second year on, cut branches are thick enough to sell. A more intensive form of FMNR is to profit from every stump sprouting on the land.

Natural / human environment: FMNR is a simple, low-cost and multi-benefit method of re-vegetation, accessible to all farmers, and adapted to the needs of smallholders. It reduces dependency on external inputs, is easy to practice and provides multiple benefits to people, livestock, crops and the environment. Tree layout will need to be carefully considered if ploughs are used for cultivation.

3.	Remove excess shoots, leave the cut leaves on the surface	Vegetative
4.	Prune any unwanted new stems and side branches (each 2-6 months)	Vegetative

Comments:

Machinery/ tools: All activities carried out manually

Annual income from selling wood: US$ 140 (from the 6th year after implementation). By some estimates, total benefit per hectare (incl. wood sales, increased crop yield, increased livestock productivity, wild foods and medicines etc) are in the order of US$ 200/ha, compared to an investment in labour US$ 10-15.

4.8 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

Main costs are in the form of labour. One man could prepare one hectare in 1–3 days, depending on tree density (labour is undertaken by the farm owner and rarely through paid labour). No inputs used; no extra tools needed, tools are available on-farm (hoe, axe, machete etc). Maintenance costs depend on tree density also and could require 1–2 days/year/ha.

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
FMNR is a simple, low-cost and multi-benefit method of re-vegetation, accessible to all farmers, and adapted to the needs of smallholders
It reduces dependency on external inputs, is easy to practice and provides multiple benefits to people, livestock, crops and the environment

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view	How can they be overcome?
Scarce presence of live tree stumps	alternatively broadcast seeds of indigenous species (reduced short-term benefits; high mortality rates)
Cultural norms and values: ‘a good farmer is a clean farmer’ (= no trees)	work with all stakeholders to change norms
Land (including trees) is treated as common property during dry season; damaging and removing trees on other people’s land occurs	create sense of ownership of trees: (1) Encourage communities to develop rules that respect property; (2) Local forestry authorities granting informal approval for farmers to be able to reap the benefits of their work.
