## Question

Describe the LEP approach with suitable examples and list out the advantages and disadvantages of the LEP approach.

## Short answer

The LEP approach uses local labour, protects the environment and involves the community in local infrastructure projects. Advantages include local employment, low cost, environmental protection and community ownership. Disadvantages are slow progress, difficult quality control and possible elite capture.

## Answer

The **LEP approach** (Labour-based, Environment-friendly and Participatory approach) is a development approach for local infrastructure (rural roads, trails, bridges, irrigation, drinking water) that uses local labour as the main resource, protects the environment and involves the local community in all stages of the project. In Nepal it is adopted in the **Local Infrastructure Development Policy, 2061 (2004)** and applied in rural road and trail programmes.

#### Components
- **L – Labour-based:** local labour is the main resource; light equipment is used only where labour cannot give the required quality (e.g. compaction). Money spent goes to local workers as wages.
- **E – Environment-friendly:** the work causes minimum damage to nature: balanced cut and fill, no dumping of spoil down slopes, proper drainage, bio-engineering (planting grass, bamboo, shrubs on slopes), gradual construction to let slopes stabilise, and use of local materials.
- **P – Participatory:** the beneficiaries take part in all stages – selection, planning, design, construction, monitoring, and operation and maintenance – usually through a users' committee, with public hearings and public audits.

#### Examples
- **Green roads in Nepal:** rural roads built by local labour with balanced cut and fill, side drains and bio-engineering, introduced in the hills (e.g. in Dhading and other districts with support from GTZ and SDC) and later applied by DoLIDAR programmes such as the Rural Access Programme and DRILP.
- **Trail bridges:** local communities carry materials and provide labour; users' committees maintain the bridge.
- **Community drinking water schemes and small irrigation canals** built by users' committees with local labour and cost sharing.
- **Rural Community Infrastructure Works (RCIW)** using food/cash for work.

#### Advantages
1. Creates **local employment** and cash income; reduces poverty.
2. **Low cost** and less foreign exchange (fewer imported machines and fuel).
3. **Environment protection:** fewer landslides and less erosion, less forest damage.
4. **Ownership and sustainability:** people who build it maintain it.
5. **Skill development** of local workers and capacity of users' committees.
6. **Transparency and good governance** through public audits.
7. **Suits remote, steep terrain** where machines cannot reach.
8. **Inclusion** of women, poor and marginalised groups through job quotas.
9. Projects match the **real needs** of the community.

#### Disadvantages
1. **Slow progress**; not suitable for large, urgent or highly technical works.
2. **Quality control** is difficult if workers are unskilled or supervision is weak.
3. Needs strong **management and social mobilisation**; more time spent in meetings.
4. Possible **political interference** and capture by local elites in users' committees.
5. **Labour shortage** in villages due to foreign migration; wage rates rise.
6. Work may be **seasonal** (farming seasons, monsoon).
7. Not suitable for heavy works like highways, tunnels, large bridges.
8. Risk of misuse of funds if public auditing is weak.

| Advantage | Disadvantage |
|---|---|
| Local jobs, income | Slow |
| Low cost, low import | Quality control difficult |
| Eco-friendly | Needs good management |
| Ownership, maintenance | Elite capture, politics |

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. In LEP, the 'E' stands for environment-friendly, which includes:
   A. Dumping spoil down slopes
   B. Balanced cut and fill, drainage and bio-engineering
   C. Heavy machines
   D. Removing vegetation
   Answer: B. Environment-friendly means minimum damage using balanced cut and fill, drains and bio-engineering. (Key point: LEP components)

2. In LEP, light equipment is used:
   A. For all work
   B. Only where labour cannot give the required quality, e.g. compaction
   C. Never
   D. Instead of local labour
   Answer: B. Labour is the main resource; equipment supports only where needed. (Key point: Labour-based role of equipment)

3. Which is an advantage of LEP?
   A. Fast for large urgent works
   B. Ownership and sustainability since people who build it maintain it
   C. Needs no management
   D. Suitable for tunnels
   Answer: B. Local participation brings ownership and maintenance. (Key point: Advantage)

4. Which is a disadvantage of LEP?
   A. Elite capture and political interference in users' committees
   B. Environment damage
   C. High foreign exchange use
   D. Excludes locals
   Answer: A. Elite capture, slow progress and quality control difficulty are disadvantages. (Key point: Disadvantage)
