Breve descrição da melhor prática

Libasan small water impounding projects (SWIP) was established in Nabunturan for soil and water conservation, supplemental irrigation, and fish culture. The project consists of modified homogenous earth structure with a total storage area of 14 ha and service area of about 150-200 hectares. It has also provision for inland fishery production including fish hatchery for fingerlings production. Watershed management is a very important component of the system and was implemented through the LGU's Forest Protection Program. Seedlings (i.e. coconut, coffee and fruit trees) dispersal was initiated by the municipality thru  a strong local and community policy framework.

Condições socioeconômicas prevalecentes das pessoas que vivem no local e/ou nas proximidades

Nabunturan is a first class municipality. The total income of the municipality significantly increased by 20.8% from 86.9 million pesos in 2007 to 105.6 million pesos in 2008. The internal revenue allotment (IRA) of the municipality was 72.63 million pesos in 2008 for an equivalent of 1,078 pesos IRA per capita .
While almost 70% of the total land area is agricultural, 20% are uplands. In general there are land tenure security problems. The total area of Nabunturan base on land use pattern, rural area covered 23,432. 237 ha and the urban area totaled to 687.763. |
Due to its arable land and generally good climate, agriculture is the primary economic activity. Majority or about 68.5% of the total land area of the municipality is predominantly occupied by agricultural lands. To support its farmers, the municipality has invested in several agricultural support facilities such small water impounding project (SWIP) and communal irrigation systems.|

Com base em quais critérios e/ou indicadores (não relacionados com a Estratégia) a prática proposta e a tecnologia correspondente foram considerados como "melhores"?

Libasan  SWIP had been implemented to address both environmental targets (i.e. conservation and protection of the environment) and socio-economic targets (i.e. source of livelihoods, profitable business in agriculture and fishery) of the local village. It has improved  the way of life of the community over the years due to increased agricultural and fishery productivity as water from the reservoir is sufficient the whole year round. The local government has initiated a watershed protection program to prolong the life of the project by distributing seedlings which were planted in the watershed. The Farmers Association became stronger and more efficient in the operation and maintenance of the system though various trainings its members have attended. Thru strong leadership and cooperation among members, the Libasan Farmers Association became a multi-purpose cooperative with outstanding assets amounting to 4.1 million pesos with the LIbasan SWIP as the core facility.|

Principais problemas abordados pelas melhores práticas

1. Limited source of livelihoods
2. Inadequate water supply during dry season
3. Soil erosion, excessive surface runoff and flooding during the rainy season|

Esboçar problemas específicos de degradação do solo abordados pelas melhores práticas

Uncontrolled surface runoff, soil erosion, soil fertility decline, and flooding of low-lying areas are the major concerns in the upland  and adjoining areas of Nabunturan due to lack of defenses in the middle and upper reaches of the watershed. Yet, during dry season there is limited water supply to support agricultural activities and other related endeavors.  With limited sources of livelihoods, farmers then are forced to encroach the watershed resulting to continued deforestation that further worsened the situation. This “vicious cycle” was gradually halted by the establishment of Small water impounding project (SWIP). It acted as the first line of defense against flood in the upper reaches of the watershed. More importantly, it collected and stored surface runoff and direct rainfall that would otherwise flow directly to waterways with highly erosive velocity. It also captured eroded materials from the watershed and thus helped prevent natural waterways from becoming shallow.|

Breve descrição e especificações técnicas da tecnologia

The Libasan SWIP is currently being managed by the Libasan Primary Multi-purpose Cooperative (LPMC). It was primarily designed for soil and water conservation  by collecting direct rainfall and surface runoff  (rainwater harvesting).  It has a reservoir surface area of 14 ha which is currently being utilized for supplemental irrigation, inland fish culture, fresh water fish hatchery , and for recreation. Its present irrigation service area is 150-200 hectares. The structural component of a typical SWIP consists of the following physical features: a) earth embankment, b) spillway, c) outlet works, d) irrigation system, and e) access road.
The best practice includes forest preservation, protection, rehabilitation and   conservation of the remaining natural resources thru reforestation in the watershed.  These efforts address the problem of siltation in the reservoir and denudation of the watershed and maintain the effective storage capacity of the reservoir. Trees provided by the local government and planted in the project watershed include:
    1. Budded Rubber
    2. Coconut
    3. Coffee
In the service area, farmers raise ducks to control pests (golden snails) in the paddy field during crop vegetative stage and after harvest.

The farmers association  thru the LPMPC, being the direct beneficiaries, is the one
responsible in the operation and maintenance of the system. The Municipal Government of Nabunturan, the Provincial Government of Compostela Valley and the DA-Regional Field Units (DA-RFU) provide agricultural support services in terms of planting materials for the watershed protection, post-harvest facilities, greenhouse and even technical and financial assistance. In case of technical O & M problems, the DA-RFU thru its Regional Agricultural Engineering Division, monitors the project operation and provides technical support and assistance to the farmers. National agencies with local presence also provide agricultural facilities and inputs. This arrangement creates strong linkages among key local player and facilitates sharing of their resources to ensure project sustainability.

Descreva os dois principais impactos fora do local (isto é, não ocorrendo no local, mas nas áreas circunvizinhas)

Potential reduction in flood  peaks in adjoining waterways.
More economic activities in the neighboring village due to  increased agricultural and fisheries production and generation of jobs

Impacto sobre a biodiversidade e a mudança climática

Explique as razões:

The development of Libasan Reservoir provides new habitat for wildlife. A variety of indigenous fish species were also stocked in the reservoir. Meanwhile, the watershed management component of the project encourages enrichment planting and maintenance of protection forest, which help maintain a healthier and more bio-diverse watershed area.
With stored water available the whole year round, the practice contributes to reducing the vulnerability of the local people and ecosystem against the impacts of climate change particularly drought. The impounding reservoir also serves as the first line of defense against flood. It helps reduce stream bank erosion and scouring through a more controlled water flow and minimize downstream siltation as it captures eroded materials from sloping lands. The continuous planting of trees in the watershed will have long term impact in terms of  carbon sequestration which  will help mitigate climate change.
