2.1 Descrição curta da tecnologia

Definição da tecnologia:

Ficus natalensis based agroforestry system protects crops on windy hill slopes facing Lake Victoria and reduce runoff towards the meandering Kagera River Valley.

2.2 Descrição detalhada da tecnologia

Descrição:

Ficus natalensis is traditionally scattered in crop fields as a land management practice in central and south-western Uganda. The improved technology designed through community participation involves planting lines of Ficus natalensis along the contour at an interval that enables the tree to provide shade to young crops without depriving them of sunshine. When planted together with coffee trees or in banana plantations, the tall Ficus tree forms the top storey that protects the crop from the hot sun.

Purpose of the Technology: The main purpose of Ficus based agroforestry is to protect the soil from erosion. Within 3 to 5 years the Ficus tree forms a deep root system that stabilizes the soil. In addition, it drops leaves which quickly decay to provide both soil cover and manure thereby increasing the fertility of the soil. The trees provide firewood, fodder for livestock and bark cloth which can be used domestically or sold to supplement household income. They also act as wind breaks.

Establishment / maintenance activities and inputs: Ficus Natalensis is propagated using cuttings from young branches which are planted vertically 6 m apart along a contour. Propagation material is readily available and cheap, making the technology inexpensive to establish. Any annual or perennial crop can be inter-cropped with Ficus spp. provided the tree canopy is managed well. The tree is quite robust and can attain heights of over 20m, with a very extensive canopy if left to grow. Pruning raises its canopy to the desired height above the ground. In its early stages, fencing is required to protect the tree from damage by livestock. Within 12 to 18 months, however, the tree is established enough to withstand browsing. Only simple tools like hoes and garden forks for digging holes/pits are essential for establishment of the technology. The implementation of the technology on steep slopes (> 50%) is not possible without other supportive SLM interventions, in Rakai these include construction of stone lines and mulch application.

Natural / human environment: The pruned branches of Ficus natalensis are used as fuel wood when dry. Therefore scarcity of fuel wood may lead to over-harvesting of branches and destroying the canopy. Nonetheless, the tree regenerates quickly with the coming of the rains. Ficus tree can live for a hundred years.

4.8 Fatores mais importantes que afetam os custos

Descreva os fatores mais determinantes que afetam os custos:

The most important factor affecting cost is labor to transport the bulky stem cuttings to the site. However, Ficus Natalensis is easy to establish and is durable (over 100 years) depending on management. It is extremely hardy and when it grows to 50cm to 100cm stem diameter it can be used for timber or to make dugout canoes. Establishment costs are easily recovered.

6.7 Pontos fortes/vantagens/oportunidades da tecnologia

Pontos fortes/vantagens/oportunidades na visão do usuário da terra
Ficus is used to provide backcloth that is sold for the making of Art and crafts and for cultural functions. How can they be sustained / enhanced? Management to accelerate healing of the bark within a shorter period should be investigated
Trees shield crops from dangerous storms /rains and intense sunshine. How can they be sustained / enhanced? Encourage the spread of the canopy
Ficus is good and attractive to birds and insects How can they be sustained / enhanced? Provision of material support in form of seedlings, farm tools for accelerated multiplication
Ficus natalensis leaves are cut and fed to livestock like goats. How can they be sustained / enhanced? Encourage indeginous trees and growing fodder crops such as calliandra and nappier grass

Pontos fortes/vantagens/oportunidades na visão do/a compilador/a ou de outra pessoa capacitada
Demand for wood fuel is high How can they be sustained / enhanced? Local bye laws should be enacted to control deforestation and encourage tree growing
It improves soil fertility-Ficus natalensis sheds leaves once every year, adding to soil humus. How can they be sustained / enhanced? More guidance should be given to the farmers for sustained spontaneous adoption of the technology
It checks the speed of wind thereby protecting crops. How can they be sustained / enhanced? Other agricultural, ecological and social benefits could be explored in this scenic area facing the Kagera River where it enters Lake Victoria
Stakes made from the Ficus branches can be used to grow climbing plants eg. passion fruits, yams as well as climbing beans How can they be sustained / enhanced? More tree planting should be encouraged
Prevents soil erosion by checking raindrop splash, speed and amount of surface runoff and stabilizes the soil. How can they be sustained / enhanced? Because the ficus tree takes time to establish, other technologies such as trenches and grass strips could be used to reinforce it
