Comentários:

Based on the responses provided by the interviewee (Group Chairman), it appears that electric fences may not directly contribute to mitigating land degradation. However, they can be considered as part of a technological approach, particularly in terms of adaptation, given their effectiveness in land restoration, fallow land reversion, ensuring food security, and ultimately enhancing livelihoods.

2.2 Descrição detalhada da tecnologia

Descrição:

The Electric Fencing System in Bhutan serves as a non-lethal approach to safeguarding crops from wild animals, aligning with the principles of Gross National Happiness (GNH). GNH emphasizes values such as compassion, non-killing, and harmonious coexistence with nature.
The National Plant Protection Centre (NPPC), Department of Agriculture (DoA), Ministry of Agriculture and Livestock (MoAL) has been facilitating the application and installation of electric fence systems nationwide. This is achieved through the provision of comprehensive guidelines to help the public comprehend the fundamental components and installation procedures.
In essence, the electric fence system consists of three major parts: Energizers, Insulators, and Earth return. The energizer is responsible for generating high-voltage pulse electricity (ranging from 9-12 KV), which is then delivered along the fence wires. The majority of energizers are directly connected to the electricity line, while in some isolated cases, solar panels and batteries are used as alternative power sources. Insulators are typically crafted from a non-conductive material and serve as a barrier between the electrified wire and the wooden post. In the Bhutanese market, these insulators are not readily available, thus as an alternative, high-density polyethylene (HDPE) pipe has been found to be effective and cheap. The electric fence earth return serves as an essential pathway in the electric circuit, collecting high voltage and current from the earth and returning it to the energizer.
The loss of crops to wild animals leads to increased production costs in Bhutan (time spent in crop guarding) and the expansion of fallow lands. Farmers often resort to illegal and fatal methods of electric fencing, tapping electricity directly from the main line. To address these issues, the implementation of electric fencing, utilizing imported IEC-certified energizers and locally fabricated fencing materials, has proven to be successful. This electric fencing system, introduced after five years of pre-testing across the country, covers various locations targeting different problem species of animals. Not only is this technology effective in controlling wild pests, but it also enjoys high social acceptance among Bhutanese farmers due to its cost-effectiveness and being non-lethal to wild pests.
A recent study on the impact of electric fencing on food security focused on the Laptsakha community in Senggye Gewog, Sarpang Dzongkhag. They faced threats to food security from elephants, boar and stray cattle from neighboring communities in India. Crop production in Laptsakha was negligible before the introduction of electric fencing: resettled households contemplated returning, fertile lands were left fallow, and incomes shrank. The turning point came in 2013 with the introduction of electric fencing. This intervention successfully mitigated wildlife attacks on crops, ensuring food security and contributing to a harmonious ecosystem and improved livelihoods for the people of Laptsakha.
The electric fence, covering a distance of 7 km, protects a total of 60 households in all, safeguarding about 60 (24 ha) acres of vulnerable lands. Electric fences have various benefits including:
•Harmonious Approach: they do not cause harm to animals beyond a repellent shock.
•Economical and Easy to Build: they are cost-effective and relatively easy to construct.
•Learning and Deterrence: animals quickly learn to respect electric fences.
•Durability: they have an extended service life.
•Versatility: they offer a variety of designs and can control a wide range of wild animals.

The installation of an electric fence involves a participatory approach and several key steps:
•Location and Length: determine the location and approximate length of the electric fence either by manual measurement, or remote technologies for larger expanses.
•Material Estimation: estimate the required materials per kilometre based on the identified area, including wooden poles, HDPE pipe, and GI wire.
•Additional Materials: Consider other essential materials like energizers, solar panels, charge controllers, and batteries, depending on the specific requirements.
•Cost Estimation: Calculate the cost of installation, which varies regionally. For example, to instal one kilometre of an electric fence is estimated at about Nu. 7,450 (USD 95) excluding labour costs and cost of wooden poles which is sourced locally.

The implementation of electric fencing in the community has brought significant advantages, particularly in securing food. Prior to this intervention, the community faced severe challenges in harvesting crops, with approximately 70% of fertile lands being left fallow due to constant human-wildlife conflicts. Crop guarding became routine & risky.
With the introduction of electric fences, the community's agricultural landscape has undergone a positive transformation. Crop diversification has been enhanced, encompassing maize, ginger, paddy, mandarin fruit trees and areca nut. The frequency of wild elephant attacks has significantly decreased, leading to a notable increase in crop production. This has resulted in secured food sources and improved livelihoods. Additionally, the community has successfully revived previously fallow lands.
While the electric fencing has proven effective, there are challenges faced by the land users, notably the frequent damage to energizers, primarily attributed to thunderstorms. This has resulted in higher maintenance costs. In one specific instance, the community had to mobilize approximately Nu. 145,000 (USD 1800) independently to replace damaged energizers and other materials, supplementing the continued support from the government.

• Não (Continuar com a pergunta 3.4)

Comentários:

The introduction of electric fencing in the community has not led to a change in land use patterns. However, there has been a notable transformation in land cover over the years. Prior to the implementation of electric fencing, approximately 70% of the currently cultivated lands (comprising 325 acres, including 168 acres of dry land and 157 acres of wetland) were left fallow due to the threat of wildlife (human-wildlife conflict). The introduction of electric fencing has played a crucial role in revitalizing these fertile fallow lands, bringing them back into cultivation.

Comentários:

The labour contribution was from Laptsakha and Nichula villages as the electric fencing benefitted both villages. Therefore, a higher number of land users are involved in the construction of the technology.
The total cost for the establishment of the technology is USD 7614.05 for 7 km (USD 1087.7 for 1 km). This includes labour cost which is borne by the land users.

4.5 Atividades recorrentes/manutenção

1.	Replacement of energizers during breakdowns	As and when breakdown occurs
2.	Fence line clearing	Monthly

Comentários:

Between 2013 and 2019, approximately 20 energizer sets had to be replaced due to thunderstorm damage. To address this issue, the community transitioned to using solar-powered energizers instead of electricity, proving to be a more effective solution. Double batteries were employed to ensure consistent current flow during cloudy days. As part of the routine maintenance, the clearing of the fence line became a monthly task, with each household assigned an area of approximately 116 meters to manage.

7.4 Comentários gerais

The questionnaire is not easy to apply for such technology in terms of sections 2.5 and 4.2. Under section 2.5 “specify the spread of the technology” the options are not applicable for this technology implemented in 7 km length. Under section 4.2. it is difficult to specify units for the cost calculation. The cost for overall technology implementation can be added. However, the cost specified in km is not uniform. For example, the cost for 1 km could be USD 95 but for 2 km it will be less than USD 190 as there is no need for two energizers and other accessories.
