It creates employment, reduces landslides and builds local ownership. ## Answer The **LEP approach** – **Labour-based, Environment-friendly and Participatory** – is a strategy for building local infrastructure (rural roads, trails, trail bridges, irrigation, drinking water, school buildings) that uses local labour as the main input, minimises environmental damage and involves the community at every stage. Nepal adopted it in the **Local Infrastructure Development Policy, 2061 (2004)**, and it is applied by local governments and rural infrastructure programmes. #### 1. Labour-based - Local labour is the main resource; light equipment (rollers, tractors for haulage) is used only where labour cannot give the required quality or is uneconomic. - Quality and cost are kept comparable to machine-based work. - **Benefits:** jobs and cash income for poor households, skill development, money stays in the local economy, less import of machines and fuel. - *Example:* earthwork, stone masonry walls, gabion walls and drains of rural roads done by local workers. #### 2. Environment-friendly - **Balanced cut and fill:** excavated soil is reused, not dumped down the slope. - **Proper drainage:** side drains, cross drainage, cascades to control runoff. - **Bio-engineering:** grass, shrubs, bamboo and trees planted on slopes to prevent erosion. - **Phased construction:** road is opened in stages, letting slopes settle through a monsoon. - **Minimum tree cutting** and use of local materials (stone, timber). - *Example:* "green roads" in Nepal's hills, which cause far fewer landslides than bulldozer-built roads. #### 3. Participatory - Community identifies needs and priorities. - A **users' committee** is formed, including women and marginalised groups. - Community contributes labour, materials or cash (cost sharing). - Public hearings during work and **public audit** at the end ensure transparency. - Users take responsibility for operation and maintenance. #### Steps in an LEP project ```text Need identification (PRA) -> Users' committee formation -> Survey and design (engineer + users) -> Agreement and cost sharing -> Construction with local labour -> Monitoring and public audit -> Handover, O&M by users ``` #### Advantages - Employment and poverty reduction - Low cost and low import dependence - Less landslide and erosion; sustainable - Local ownership; better maintenance - Transparency and empowerment #### Limitations - Slower construction - Quality control needs good supervision - Labour shortage due to foreign migration - Elite capture and political interference - Not suitable for large highways, tunnels and big bridges LEP thus links infrastructure building with employment, environmental care and local empowerment, making it well suited to rural Nepal. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1. What is a benefit of the labour-based element? A. Higher import of machines and fuel B. Money stays in the local economy through jobs and income for poor households C. Faster work than machines always D. Fewer local skills Answer: B. Local wages create income and skills and keep money in the local economy. (Key point: Labour-based benefits) 2. Why is a road opened in phases in the environment-friendly approach? A. To increase the cost B. To delay the project deliberately C. To let slopes settle through a monsoon D. To avoid drainage Answer: C. Phasing allows slopes to stabilise and reduces landslides. (Key point: Phased construction) 3. What is the role of public hearings and public audit in LEP? A. Replace the users' committee B. Select the contractor C. Reduce labour D. Ensure transparency in the work Answer: D. Hearings during work and an audit at the end ensure transparency. (Key point: Public audit) 4. Which is a limitation of LEP? A. Suitable for tunnels and large highways B. Not suitable for large highways, tunnels and big bridges; may be slower C. Always faster than machines D. Requires no supervision Answer: B. LEP is slower, needs good supervision and does not suit large highways, tunnels and big bridges. (Key point: Limitations of LEP) ## Related in Technology, Environment and Society - [Participatory approach, appropriate and labour intensive technology](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Aparticipatory-appropriate-labour) — Technology, Environment and Society, chapter 1 - [Participatory development approach](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Aparticipatory-development-approach) — Technology, Environment and Society, chapter 2, asked 2× - [LEP, ethnographic and participatory approaches](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Alep-ethnographic-participatory) — Technology, Environment and Society, chapter 2 - [LEP approach: advantages and disadvantages](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Alep-approach-adv-disadv) — Technology, Environment and Society, chapter 2, asked 2× - [Participatory approach and four participatory tools](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Aparticipatory-tools-empowerment) — Technology, Environment and Society, chapter 2 - [Participatory approach for community empowerment](https://www.bctengineer.com/question.md?key=semester_7%2Ftechnology_environment_and_society%3Aparticipatory-empower-community) — Technology, Environment and Society, chapter 2 ## Related in other subjects - [Human civilization, development and the environment](https://www.bctengineer.com/question.md?key=semester_7%2Fenvironment_and_pollution_control%3Acivilization-development-environment-history) — Environment and Pollution Control, chapter 7
