2.1 Descrição curta da tecnologia

Definição da tecnologia:

Area closure on degraded lands is a land management practice used to rehabilitate and conserve the natural resource bases, and enhance its natural regeneration and restoring capacity and productive functions by excluding animal and human interferences through community consultation and collective actions.

2.2 Descrição detalhada da tecnologia

Descrição:

Area closure is a land management practice that helps to rehabilitate degraded lands, restore the biophysical conditions like soil, vegetation and hydrology by avoiding the interference of animals and human. Because of over grazing and erosion impact, areas delineated for closure are usually degraded shrub or pasture lands that served for grazing. First of all, implementing area closure requires continuous dialogue and discussion with community to reach consensus to close. The community wants to make sure they have benefited from the technology as the land was serving for grazing. They should take the responsibility and create sense of ownership to implement conservation measures, protect and maintain closure areas, and regulate utilization of benefits gained out of it. Questions raised from the community must be discussed thoroughly ahead of the implementation. What part of the degraded land? For what purpose the area is closed? Who are the users? Who are responsible to protect and manage the developed resourcess? How is the benefit sharing among identified users? Commonly, the shared benefits from area closures are hay for livestock through cut-and-carry system, timbers from plantations, and honey production.
Depending on the soil, rainfall and slope conditions different structural and vegetative measures are integrated to enhance the fast regeneration of plant species, restore the soil and increase water availability. It includes enrichment used to rehabilitate and increase the vegetation cover, vegetative and structural measures to retain the soil and water on its place. Structures such as hillside terrace often integrated with grass or shrub hedgerows is used to control soil erosion. In-situ water harvesting structures such as trenches or half moon or eye brow are used to harvest and infiltrate rain or runoff water to increase regeneration and survival of planted trees. Trees and/or shrub species that have high rehabilitation and multipurpose values are used as enrichment plantations. Closed areas need collective action to protect, maintain and manage the common resources. Collective user rights have to be entitled to bring equity on resource sharing and minimize social conflicts.

The purposes of area closure are: 1) rehabilitate degraded lands, 2) protect and restore the natural resource base, and 3) change into productive land and enhance economic and environmental functions of rehabilitated lands.

Implementation of area closure begins with the selection and demarcation of area through genuine participation of land users. After identifying the area to be closed, at establishment stage construction of ditches and terraces is made using stones combined with grasses or shrubs of multipurpose value such as Vetiver grass, Dinsho grass, Bana grass, susbania, etc. Depending on site conditions, enrichment tree species which have rehabilitation and soil restoration purposes are planted in the form of wood lot or scattered tree plantation. Among the common species, A. albida, A. saligna, A. decurrense, Gravilia robusta, etc. are used to rehabilitate and serve as fuel wood and timber. In moisture stress areas structures like trench, level bunds, and half moon should be constructed to increase survival rate of planted tree/shrub species whereas in areas having sufficient moisture these structures, depending on the landforms and soil drainage conditions, help to increase infiltration and recharging of ground water in downstream areas. Therefore, site selection and demarcation, construction of soil conservation and moisture conservation structures, and seedling management and plantation of multipurpose trees, shrubs and grasses are the activities accomplished at establishment stage of area closure. The required inputs are stones, seeds/seedlings, grass cuttings/splits, hand tools, and collective labor. For recurrent maintenance activities, seedlings and cuttings for re-plantation purpose or replace dead seedlings, stones to repair damage stone terraces and moisture conservation structures. Harvesting and transporting of area closure products such as grass and timber become a recurrent activity. Person days per hectare per year required for plantation (preparation of holes and planting) is 11.5, for harvesting and transporting harvested grass is 30, and for terrace construction is 26.5.

Area closure management is commonly practiced on degraded hills where soil is highly depleted, its water holding capacity is low, and vegetation is denuded. Usually degraded lands are used to serve for communal grazing system. The degree of land degradation becomes severe where there are high livestock and human population pressure. Management of closure area and the benefit sharing has to be regulated using agreed bylaws.

The living condition depends on subsistence crop-livestock mixed farming. On average households have 5-6 family size. Crop production is meant for home consumption with small surplus for local market. The services related to water supply, energy supply, and infrastructure are low. Besides it is an asset, animals often used to cope shocks during drought periods.

6.4 Análise do custo-benefício

Como os benefícios se comparam aos custos de implantação (do ponto de vista dos usuários da terra)?

Como os benefícios se comparam aos custos recorrentes/de manutenção(do ponto de vista dos usuários da terra)?

Comentários:

Short term economic benefits can be attained by harvesting forage biomass for livestock while in the long term downstream agricultural productivity can be improved as they witnessed the change in stream flows to be used for irrigation. This is very much pronounced in Aba Gerima watershed where farmers in the downstream get to access more water.

6.5 Adoção da tecnologia

Comentários:

The technology is implemented in group or at community level.
The spontaneous adoption of this technology is possible without integrating plantations of improved trees/shrubs and grasses
There is a moderate trend towards spontaneous adoption of the Technology
Adoption to area closure is increasing as it provides better pasture for livestock and benefit those who do not have power or for poor community groups

6.7 Pontos fortes/vantagens/oportunidades da tecnologia

Pontos fortes/vantagens/oportunidades na visão do usuário da terra
Increase in vegetation cover and biomass production for livestock feed

Decrease erosion
Decrease transmission of animal disease often a problem during open grazing system

Pontos fortes/vantagens/oportunidades na visão do compilador ou de outra pessoa capacitada
Increase the fodder and grass biomass production for livestock feed
Increase the regeneration of lost plant diversities
Create alternative livelihood options (off farm activities like honey production, timber, tree or fodder seed production)
Enhance the micro-climatic conditions and on-site vegetation cover, organic matter, and soil water holding capacity. In addition it improves off-site surface and subsurface water flows

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?
Land users' perceived that implementation of the technology decreases open access to communal pasture lands to maximize their benefit	Awareness creation activities has to be provided
Shortage of labor to harvest and transport forages to feed animals	Cost effective technologies to prepare feed, handle and transport forage has to be introduced and adopted. It can be overcomed by organizing service provider groups.
The amount of pasture/fodder produced and shared among users is much less than the feed requirement of all animals hold by a household	Introduce fodder species producing high biomass and high quality fodder; decrease livestock number per household.

Pontos fracos/vantagens/riscos na visão do compilador ou de outra pessoa capacitada	Como eles podem ser superados?
Labor constraint for cut-and -carry for stall feeding	It can be sustained through organizing service providers groups
Stall feeding restricted the cross breeding of animals in the village easily accessible during open grazing	Artificial insemination and bull services and synchronization breeding system has to be promoted
