1.4 Declaração de sustentabilidade da tecnologia descrita

A tecnologia descrita aqui é problemática em relação a degradação da terra de forma que não pode ser declarada uma tecnologia de gestão sustentável de terra?

Não

Comentários:

The technology supports the rehabilitation of degraded rangelands; the Vallerani plough forms micro water harvesting pits suitable for native shrub seedlings. This boosts vegetation recovery through both out-planted shrubs and the emergence of local seeds.

2.1 Descrição curta da tecnologia

Definição da tecnologia:

Mechanized micro water harvesting breaks up crusted and compacted soils, and fosters the capture and retention and the deep-infiltration of surface runoff generated during heavy rainfall events. The micro water harvesting pits store water and provide soil moisture to the out-planted shrub seedlings and the emerging seeds - and thus boosts the development of resilient vegetation patches towards the eventual rehabilitation of degraded rangelands.

2.2 Descrição detalhada da tecnologia

Descrição:

The micro water harvesting technology is part of a larger watershed rehabilitation initiative; It is the most upstream technology used in an integrated approach, including upland rehabilitation (Vallerani), gully erosion control, and revegetation (gully plugs), and downstream local barley agriculture using the ‘Marab’ technology.

1: Main Elements: The Vallerani tractor plow (Delfino 50 MI/CM) (Gammoh & Oweis, 2011) constructs intermittent water harvesting pits along the contour of terrain and transects the hill slopes at approximately 5-10 m between lines. The local hill slope (at the implementation site) ranges between 2% and 15%. Pit length is adjustable and relates to the speed of the tractor. At the implementation site, pit lengths are around 4.5 m. In the micro water harvesting pits, several native shrub seedlings can be out-planted (at the site, 2 per pit).

2: Where: This technology is used in a watershed context close to Al Majeddyeh village, located in the Middle Badia zone, approximately 30 km south-east of Amman. The climate is arid and warm (Palmer, 2013). The average annual rainfall is around 130 mm. The natural environment is classified as steppe, Bsh in the köppen classification. The human environment is characterized by agropastoralists. They are semi-nomadic and live in villages around the watershed, for example, Al Majeddyeh village.

3: The purpose of the technology: Breaking the land degradation cycle by retaining and encouraging deep-infiltration of surface runoff, which supports native vegetation growth. The stored soil moisture boosts the growth of both out-planted shrub seedlings and emerging local seeds towards healthy and resilient vegetation patches. Over time, the plowed pits degrade, but vegetation takes over the dryland hydrological functions of rainfall interception, runoff deceleration, and fostering infiltration. The developing shrubland provides various ecosystem services, predominately fodder for livestock of local agropastoralists.

4: Major activities: 1) Mechanized micro water harvesting establishment through the Vallerani tractor plow. 2) plantation of native seedlings in the pits (2 shrubs per pit at the local site). 3) Manage rangelands through sustainable grazing.

5: Impact: The technology breaks up the degradation cycle, increases soil moisture, and eventually boosts vegetation development and biodiversity. Through retention of runoff, sediments and residues, it decreases erosion and enhances organic carbon storage. It reduces peak surface runoff and thus mitigates flooding. The enhanced biomass supports livestock (grazing) and reduces agricultural inputs required (such as those required for low input barley production).

6: Land users' opinion: Land users evaluate the technology ambivalently. In the short term, landowners are often skeptical, because the rehabilitation requires a recovery time and strict non-grazing/resting for (usually) the first 2 rainy seasons. Thereafter, the rehabilitated lands require sustainable management. Later, after vegetation development, most landowners are convinced of the improvements and understand the economic and environmental value. The acceptance strongly depends on the social and cultural context – many farmers continue preferring the already established barley monoculture, mainly due to lack of sustainable rangeland management options and land ownership. However, well-targeted awareness campaigns can be supportive.

Comentários:

The shrub seedlings used were of high quality. A local community was used for labour. These two items increase costs per hectare – costs per hectare can be significantly reduced using ‘cheap’ seedlings or professional agricultural labour. However, the purpose of the project was local community inclusion and their benefit.

	Atividade	Periodicidade/frequência
1.	Sustainable grazing (take half / leave half concept)	1-2 times per season
2.	Cut and carry	locally
3.	Resting for shrub-seed production and new recruitment	Some selected resting seasons

4.6 Custos e entradas necessárias pata a manutenção/atividades recorrentes (por ano)

Comentários:

The technology aims at re-establishing a sustainable nature-based ecosystem. Once properly implemented and managed, no further maintenance is needed. Certainly, ‘costs’ during biomass facilitation accrue through, e.g., herding and watering of livestock; however, these costs are not considered to occur because of the landscape improvement.

6.7 Pontos fortes/vantagens/oportunidades da tecnologia

Pontos fortes/vantagens/oportunidades na visão do usuário da terra
Opportunity for agro-pastoralism (grazing up to twice a year)
Improved livestock health, milk quantity, and quality.
No input costs needed (compared with e.g. barley agriculture)
Flexibility in timing: grazing of healthy rangelands can be done ‘at any time’(certainly spring season is most beneficial for livestock) – which differs from barley agriculture approach.

Pontos fortes/vantagens/oportunidades na visão do/a compilador/a ou de outra pessoa capacitada
Besides out-planting of native shrub seedlings, native biodiversity evolves through the emergence of dormant seed material.
Out-planted shrub seedlings withstand extreme weather conditions (droughts) through water harvesting. The survival rate and eventual success of the rehabilitation approach are high.
Micro water harvesting structures and upcoming vegetation patches reduce erosion and increase trapping of sediments, including organic carbon and seed materials.
Water harvesting reduces the peak of surface runoff and thus mitigates downstream flooding

6.8 Pontos fracos, desvantagens/riscos da tecnologia e formas de superá-los

Pontos fracos/desvantagens/riscos na visão do usuário da terra	Como eles podem ser superados?
Costs of implementation and availability of high-quality seedlings and the Vallerani plow.	Develop large-scale procedure/initiative that allows farmers to request and restore vulnerable areas using the Vallerani micro-water harvesting technique. Include incentives for implementation (ex. free seedlings, free of charge using of Vallerani machine, subsidies on arley as fodder for the first two years in order for farmers to maintain the site)
Change: Not all farmers are willing to forgo barley agriculture	Demonstrating the effects this technology through pilot projects. Local communities on the forefront of communication.
Vegetation growth may attract herders from different areas.	Clear rules and legislation on land facilitation in terms of grazing.
Requires higher understanding of the environment and long-term planning	Introduce knowledge sharing events to teach local farmers on the effects of land degradation and the benefits of healthy ecosystems

Pontos fracos/vantagens/riscos na visão do/a compilador/a ou de outra pessoa capacitada	Como eles podem ser superados?
Land ownership: current land tenure system in Jordan slows the adoption of the intervention. A landowner can reside in a city (no much value for the land), and the land user may be a herder. A large flock owner can rent huge areas for barley cultivation (actual cost of 1 donum of barley plantation ranges between 1.5-3 USD; possible to prepare up to 10 ha per day). Cheap labor/herders will move flocks and graze until all cover is gone (usually for 1-3 months maximum per year (March-May)). Rehabilitated areas will be of less interest for such users.	Develop and apply strict land management plans and policies. Create a strong monitoring system. Apply penalties for actions that increase land degradation with various on-site and off-sites impacts
Lack of institutional collaboration for rangeland management and rehabilitation. Land management in the Badia is the responsibility of several ministries in Jordan. The lack of institutional collaboration and the absence of the rangeland areas' valuation create a difficult environment for sustainability measures.	Increase the collaboration between ministries and stakeholders. Evaluate the impact of restoration solutions on the site and off site.
Lack of clear government policy for restoration, incentives for farmers, and funding availability.	Develop a clear action plan among the responsible government institutions of restoration activities.
Complex social context. The majority of land users and/or landowners don’t value the restoration. The bare cultivation practices have more (quick) value without resting time.	Capacity development for local communities for the value of soil, water, and biodiversity

7.4 Comentários gerais

The Marab is a local downstream water harvesting measure in an integrated watershed context, where up/midstream users and applied land management practices affect the Marab.
The technology diverts and spreads excess runoff over deep-soil flood plains. The technology comprises local gully-filling, grading/leveling of seedbed, and construction of a bund-and-spillway system creating several compartments for flood-irrigated agriculture.
