Muvuca Direct Seeding

Similar names: Seed-based land restoration, Direct sowing

Muvuca direct seeding is a nature restoration method, where a mix of seeds from dozens of native species at different successional stages are planted simultaneously into the ground. The method mimics natural regeneration mechanisms such as seed soil banks and seed rain. Better known conventional practice is direct seeding’s popular counterpart – transplanting, which is a technique of moving plants from one location to another, usually to preserve the optimal condition of the seedlings. Despite providing more control over the plant’s growth, transplanting doesn’t allow for a high variety of plant seeds to grow simultaneously.

The Muvuca system uses a high diversity of species and ensures longer-term operational efficiency, which in return enables mechanised restoration with reduced planting, low maintenance in terms of time and reduced costs. Planting can be done either manually or mechanised (using machinery such as tractors), which enables the scalability of the intervention. Furthermore, the grown plants through Muvuca become more robust and resistant to various weather conditions, which results in stronger root systems and overall healthier vegetation. Overall, Muvuca direct seeding can contribute to the scaling up of restoration efforts, while reducing costs and increasing the species diversity. Meanwhile, the demand for native species enables the promotion of conservation and well-being.

Gully Rehabilitation Stem Cuttings

Similar names: Gully Plugging with Stem Cuttings, Check Dams from Stem Cuttings, Brushwood Check Dams, Live Check Dams

Gully Rehabilitation Stem Cuttings is an intervention that “plugs” particularly active gullies and streams by building Check Dams made of Stem Cuttings to control erosion and runoff. These living barriers are efficient in slowing down runoff water and stopping sediment buildup in the gullies. Field research has proven that they work well in soils of sandy/loamy texture, where the performances of these dams are greater than ones made of stone dams due to rooted poles and the stabilised root system of the living barrier.

Stem Cuttings involve taking sections of woody stems from suitable plants and inserting them into the soil in a gully or erosion-prone area. These stems will develop roots and grow into new plants, helping to stabilize the soil and prevent further erosion. Stem Cuttings are cost-effective and environmentally friendly, promoting natural vegetation growth, and enhancing biodiversity, and ecosystem health. They also provide erosion control once established, preventing further degradation of the gully.

Fencing

Fencing around eroded soils, rills and gullies is a cheap and low-maintenance form of sediment catchment, soil and water runoff prevention on gentle, moderate and steep slopes. Three types of fencing are detailed in this intervention about their prevention of different types of soil erosion at varying topographies.

  1. Silt Fences → Softer intervention for sediment catchment, preventing runoff and wind displacement on rills, arid fields or gentle hillsides. 
  2. Woven Fences → Harder intervention for slope stabilisation and sediment build-up in gullies and rocky mountainous landscapes.
  3. Biotrampas → Harder intervention for rock catchment, landslides and slope stabilisation in gullies and heavily eroded, steep mountainous landscapes.
