2.1 Descrição curta da tecnologia

Definição da tecnologia:

A rubble stone wall demarcates the community forest of Nakina Village and acts as a protective barrier against wildfire, wildlife, grazing, and human encroachment. The stone wall fencing is complemented by a firebreak, which is a gap of 2 meters. Firebreak establishment requires the removal of pine needles and debris from the border of the wall, so as to reduce the fuel load and possibility of fire spreading to the community forest.

2.2 Descrição detalhada da tecnologia

Descrição:

1. The technology has applied in the natural environment (Nakina Van Panchayat)
2. Characteristics of the technology:-
It is a dry stone wall in the community forest.
The wall (3.15km, 1m height, 80 cm width) is 40 years old and is being regularly maintained. The community is currently extending it to 4km.
3. Purpose and function of the technology:-
To protect the forest from forest fires.
To protect the fodder grasses from grazing animals
To protect the community forest from encroachment
To make a margin between two community forests.
4. Major activities and inputs needed to establish and maintain the technology:
Obtaining funding and external support to make the stone wall from other agencies (JICA, Forest Department)
The Forest department and Nakina Van Panchayat were the implementing agencies, and received approval from the District Magistrate to build the wall.
Nakina Van Panchayat organized the community people to construct the wall, paying each person 400 INR ($5.20 USD) a day for their work.
The community pooled their own construction materials and rocks were gathered on site.

5. Benefits and impacts of the Technology:
-Helps to protect forest fires from spreading to the Nakina community forest (physical barrier)
-Protect the fodder grasses from grazing animals
-Avoid conflict between two community forests and deter outsiders from crossing the wall

6. Impacts of the technology:
The wall is successful in protecting the forest from wildfire and it inhibits wildlife/livestock movements or passage.
The people of Nakina village are restricted to a particular area to collect fodder and forest products, which helps them regulate and realize their specific resource demands. This helps them avoid overexploitation of forest resources and set limits.

People views about the technology:-
Like: People are very positive about this technology and they believe that extending its length from 3.15km to 4km will further benefit the forest.
Dislike: The aesthetic of the forest is slightly compromised due to the construction wall.
During construction period, the people realized that some noise pollution from breaking stones could have disturbed neighbors grazing their livestock or other wildlife

Uttarakhand Forest Department, JICA

Comentários:

The costs of extending the wall to 4km are included in the maintenance costs. "Unskilled laborers" or villagers are payed by the communal funds contributed to the Nakina Van Panchayat.
There is however some remaining financial support from JICA/Uttarakhand Forest Department to maintain the wall (e.g. money to cover the replacement of broken or stolen tools) and technical engineer who comes for periodic checks on the construction progress.

For the current wall extension, the land users are paid by the funds and colletive savings managed by the Nakina Van Panchayat.

5.3 Solos

Caso disponível anexe a descrição completa do solo ou especifique as informações disponíveis, p. ex. tipo de solo, PH/acidez do solo, nitrogênio, capacidade de troca catiônica, salinidade, etc.

Mountain/hill soils are a collective name given to various types of soils found under the following conditions :
-under sub-tropical, temperate and sub-alpine conditions
-under various forest types

Characteristics: very thin, fertile, and may be less than a centimeter deep on steep slopes; they are mixed with pebbles, shingles (a mass of small rounded pebbles), and gravels; they have a low-medium water holding capacity. Angular and subangular fragments of parent rock may be found mixed with the lower layers of the mountain and hill soils.

Texture: varies from loamy to sandy loam.
Soil Reaction: ranges from acidic to neutral (pH 4.6 to 6.5)
Organic Matter content: 1-5%

Ferrugenous red roils are found in this district and are well developed over Himalayan rocks (quartzite, biotite schist, amphibolite schist). They are free of carbonates and deficient in nitrogen, humus and phosphorus, light textured, porous, and friable (brittle/crumbly). The soil depth ranges from about 10cm-75 cm. These soils may be grouped into two on basis of morphology

1. Red earths- loose, friable topsoil rich in secondary concretions (hard, compact mass of matter formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil)
2. Red loam- argillaceous soils having a blocky structure (argillaceous minerals may appear silvery upon optical reflection and are minerals containing substantial amounts of clay-like components, e.g. argillaceous limestones are limestones consisting predominantly of calcium carbonate, but including 10-40% of clay minerals)

Brown soil: is found particularly under dense broadleaved temperate and sub-alpine forests. There occurs a thick layer of humus on the forest floor (made of decomposed leaves, branches, twigs) and the topsoil is extremely rich in humus

Podsolic Soil: soil that has developed in humid/temperate conditions usually under coniferous forests (e.g. deodar, blue pine, fir, spruce) over quartzite, granites, schists and gneiss.

5.4 Disponibilidade e qualidade de água

A salinidade da água é um problema?

Não

Ocorre inundação da área?

Não

Comentários e outras especificações sobre a qualidade e a quantidade da água:

Quantity: Water crisis has been a perennial problem in both the rural and urban areas of the Pithoragarh district
There is scarcity of safe drinking water of the villages in the study area. Hand pumps are often not functioning, pipe-water schemes are unreliable and the spring discharges have reduced during the dry season. Hand-pumped water often has a high iron content and bitter taste. Poor quality of groundwater in some of the naulas is mainly due to misuse and/or disuse of the structures.

A block-district groundwater resource estimation could not be carried out as the area is hilly (with slope >20%) and in major part aquifers are small, isolated bodies, and groundwater abstraction is done mainly through hand pumps and springs with small discharges.

However, we collected some physicochemical parameters that indicate the water (sourced from springs) is of good quality:

Water Quality Parameters of Springs:
pH: 6.29-8.18
Temp: 19.0-23.5 ºC
Electrical Conductivity: 109-504 µmsiemens
Total Dissolved Solids: 75-385 ppm

Other Parameters (from springs of nearby district, Champawat)
Electrical Conductivity: 127-222 µmsiemens
pH: 7.69-8.24
Calcium: 16-36 mg/l
Magnesium: 4.9-7.3 mg/l
Bicarbonate: 61-134 mg/l
Chloride: 5.3- 8.9 mg/l
Total Hardness as CaCO3: 70-110 mg/l

5.5 Biodiversidade

Comentários e outras especificações sobre biodiversidade:

Uttarakhand has more than 7000 species of medicinal plants and 500 species of fauna. Floral diversity contributes 31% of total floral density of India. Fauna contributes just 1.58% of the total faunal density of the country. There are 119 endemic species of flowering plants in the state that exhibited 2.35% endemism and 35 faunal endemic species. Because it lies at the juncture of India, Nepal and the Tibeten Autononmous region, there often cases of poaching and smuggling of wildlife contrabands, including bear bile, musk pods and leopard skins through the borders. Yarsa Gumba Ophiocordyceps sinensis, commonly known as Caterpillar Fungus, is also illegally traded transboundary in the region, together with various plant species. Due to anthropogenic impacts, changes is soil quality, and climatic elements, the biodiversity of our study site is not as high as in other areas of the Pithoragarh district.

5.6 Características dos usuários da terra que utilizam a tecnologia

Indique outras características relevantes dos usuários da terra:

With recent development in Pithoragarh, an influx of funds coming from outside sources has caused a decline in the importance of agriculture production, which in now marginalized, based on female labour, and mainly conducted for subsistence with little surplus to sell. High caste men do not work in cultivation at all, and male tasks such as ploughing are performed by the Scheduled Caste.

Although most women are still cultivating, their work has lost economic importance. For most families, the produce does not cover the needs of the household and surplus must be bought from the market. Many of the terraces that were formerly fruit orchards (mainly citrus) have been completely abandoned. Farming is less intensive and landholdings are small and fragmented. The main crops are wheat, millet, and pulses, but yields are low as the land is not irrigated. Less livestock (cows, goats, buffalo) is kept because of the labor involved. Very little capital is returned to farming. Crops produced for the markets in the plains are replacing traditional crops to sustain the household.

With exposure to the“Modern” lifestyle, new values have also been accepted. Two children are the norm (the ideal being one son and one daughter, but at least one son in a must). Although access to education is quite good, it does not seem to result in working careers for women.

Direitos do uso da água:

• Acesso livre (não organizado)
• Comunitário (organizado)

Os direitos de uso da terra são baseados em um sistema jurídico tradicional?

Sim

Especifique:

Under the Kumaun Panchayat forest rules of 1931 (amended in 1976): A Van Panchayat, (community forest council), can be formed out of non-private land within the settlement boundaries of a village. Accordingly, all villagers are members of the VP upon their approval by a Sub-Divisional Magistrate under the state Revenue Department. The members are collectively referred to as the general body, which selects the management committee members through a democratic process.

Comentários:

5-9 elected members assume control and regulation of forest resources. They additionally raise funds and mobilize the village to protect and support sustainable land use. Presently 12,089 Van Panchayats are entrusted with the management of over 5,449.64 km2 of forests.

5.9 Acesso a serviços e infraestrutura

Comentários:

The situation of infrastructure is difficult and inconsistent in the hill regions because of the terrain. The major infrastructural issues are drinking water and irrigation facilities, electricity, transportation and communication facilities and social infrastructure (housing and education). As for financial services, only the State Bank of India (SBI) is active in the hill regions where it is trying to achieve the objective of 100% financial inclusion. Some villages mentioned buying into into agricultural insurance in the past, however this was a temporary enterprise and they were never compensated after extreme climatic events that occurred and damaged over 70% of their crop.

Though infrastructure and education has generally improved over the years, institutional and marketing networks in the region aimed at supporting hill-farmers are lacking.

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:

The work load is quite high for establishment and maintenance of the wall, especially when there is significant damage. Although upkeep can be demanding, the community sees the benefit of their efforts. This is especially recognized when the wall is secure from all sides and the firebreak is established before the fire season begins.

6.5 Adoção da tecnologia

• 1-10%

De todos aqueles que adotaram a Tecnologia, quantos o fizeram espontaneamente, ou seja, sem receber nenhum incentivo/ pagamento material?

• 0-10%

Comentários:

Building an extensive wall, providing necessary tools and giving compensation for the labor adds up to be an expensive endeavor. Though the community initiative to maintain the wall can be managed by the Van Panchayat, external funding is necessary for these villages in most cases.

6.6 Adaptação

A tecnologia foi recentemente modificada para adaptar-se as condições variáveis?

Sim

Caso afirmativo, indique as condições variáveis as quais ela foi adaptada:

• Mudança climática/extremo

Especifique a adaptação da tecnologia (desenho, material/espécie, etc):

The wall is being extended from 3.15 km long to 4 km. The reasoning behind this is that the community believes that it will help protect the forest at a greater scale from wildfire, as the frequency is increasing due to climate change, neglect of forest management and historical pine plantations.

6.7 Pontos fortes/vantagens/oportunidades da tecnologia

Pontos fortes/vantagens/oportunidades na visão do usuário da terra
Provides protection of the forest from forest fires and livestock grazing
More fuelwood and fodder is made available through this protective border
Because of determent from grazing and other intruders (human/wildlife), saplings and grasses are protected. This has improved the health of the forest, increased groundwater availability and improved spring recharge due to slowing surface runoff and better infiltration rates within the forest.

In agreement with the landuser

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?
Height of the wall can be too short to act as an effective barrier for intense forest fires.	The lack of height can compromised by clearing the pine needles and creating a firebreak on both sides of the wall one additional meter. Placement of vegetation where dryer areas exist (or near grassy meadows) may also act as an effective biological barrier against the fires.
Parts of the wall on steep slopes often get damaged or destroyed	Avoid building the wall on steep slopes. If there are vulnerable areas, other reinforcement or alternative building technique maybe necessary. For example, building with the incline of the slope into the mountain side, so that the wall acts as more of a retaining structure.

Pontos fracos/vantagens/riscos na visão do compilador ou de outra pessoa capacitada	Como eles podem ser superados?
The stone wall's function is only as good as its construction. Some parts of the wall appear to be built in a secure, durable manner whereas other parts could be easily perturbed by pressure or vibration.	Proper training on engineering a stable wall would benefit the technology and reduce maintenance. Perhaps an external technical person could supervise wall-restoration and make periodic checks. Emphasizing the importance of diligent work on construction can be encouraged and incentivized with a higher wage (e.g. 600 INR instead of 400).
Stone walls have inherent weaknesses against the lateral forces of earthquake. Poorly constructed walls having inadequate interlocking between the inside and the outside faces begin to separate, resulting in to rapid weakening of the wall.	Assure sure that the measures required to counter these weaknesses are taken during the construction so that in the event of a potentially destructive earthquake, the structure is able to withstand its impact without suffering much damage. It is best to build in areas that have firm soil or rock underneath the topsoil. Soft soils can amplify wall movement during an earthquake.
