I. INTRODUCTION

1. The proposed Basic Infrastructure for Inclusive Growth in the North Central Provinces

Sector Project will invest in implementation of the north central coastal provinces sub-region socio-

economic development plans. The Project responds to the Government of Vietnam's strategy of

targeting the use of concessional ODA investment into poorer provinces using economic sub-

regions as a means of identifying interconnectivity and synergies between provinces to accelerate

economic growth in provinces that have previously lagged in terms of economic growth.

2. The project has three outputs being (i) Improved connectivity within value chains and their

supporting infrastructure; (ii) Improved business development infrastructure; and (iii) Strengthened

Sub-regional infrastructure planning and management.

3. The Project has been categorized as B on environmental issues during the Project Concept

note as it has few potential significantly adverse impacts and none of them are irreversible. During

the PPTA phase, IEE report was carried out and approved in July 2017 by ADB. Anyhow, in Detail

Engineering Design (DED), scope of the subproject has changed as follow:

✓ Upgrading category V mountainous road to category IV with width from 6.5m to 7.5m;

✓ Road alignment has not been changed, only adjust some short sections to ensure safety therefore

length of the road has been changed from 23.3km to 22.81km;

✓ Construct 6 bridges instead of 4 bridges as proposed in FS.

✓ There are two new sensitive receptors arising at two new bridge

✓ The section from Trang Rong village, Hai Thai commune Gio Linh district to Ban Chua village,

Cam Tuyen commune Cam Lo district is exactly 3.0km instead of 3.5km as in FS. This section is

a trail, currently not open to traffic;

4. According to requirement in Environmental Assessment and Review Framework (EARF),

with not only extension of width and length of the road but also addition two new bridges at

Km6+450,17 and Km8+524,35 as detailed design, an updated EMP report needs to be updated and

approved by ADB.

5. The purpose of updated EMP is to reflect the changes in detailed design and relevant all

adverse impacts as well as risks on environment in order to propose adequate and effective

mitigation measures. The updated EMP takes into consideration environmental impacts and

appropriate mitigation measures base on change in approved the detailed design.

6. The subproject is entitled "Constructing and Upgrading Gio Linh - Cam Lo Inter-district

Road of Quang Tri Province" and is a representative subproject for Output 1 of the Project:

Improved connectivity within value chains and their supporting infrastructure.

7. The Gio Linh – Cam Lo inter-district road passes 2 districts, Gio Linh and Cam Lo, and

connects to provincial road 575B, and on to the Ho Chi Minh highway and to the National road 9.

The road plays an important role in socio-economic development because it provides access to the

special economic zones and commercial area at Lao Bao, to seaports such as Cua Viet and My

Thuy. Currently, vehicles transporting raw materials from Hai Thai commune, Gio Linh district to

the factories in Cam Lo commune, have to divert onto the Ho Chi Minh road and then to National

2

Road 9. The proposed subproject will reduce the transport distances and costs of transport to local

producers and improve economic efficiency for the production area.

8. The road will benefit traffic for 9,000 people of Hai Thai commune, Gio Linh district (about

4,000 people) and Cam Tuyen commune, Cam Lo district (about 5,000 people) through connecting

these people to the district centre areas. Direct beneficiaries are estimated to be over 3,400 who

will be directly involved in commerce, services, industry and agriculture in Hai Thai commune,

Gio Linh district (over 2,160 people) and Cam Tuyen commune of Cam Lo district (over 1,480

people). The road will also serve a total of 8,839ha of industrial and plantation forestry (including

rubber, coffee etc.) spread between Hai Thai commune (839ha) and Cam Tuyen commune

(8,000ha).

II. DESCRIPTION OF THE SUBPROJECT

1. Location and scope of the subproject

9. The road passes Hai Thai commune, Gio Linh and Cam Tuyen and Cam Thanh communes, Cam Lo district, Quang Tri province. The start point (Km0+000) connects to provincial road 575B

and crosses the Ho Chi Minh trail in the area of Xuan Hoa village, Hai Thai commune, Gio Linh district.

The end point (Km22+810.93) is the T-junction with National Road No.9 at Km31+120 (which is

Km17+380 before) in the area of Quat Xa village, Cam Thanh commune, Cam Lo district.

10. The subproject is basically located on the existing alignment, except for a 3.0 km section from Trang Rong village, Hai Thai commune Gio Linh district to Ban Chua village, Cam Tuyen

commune Cam Lo district. This section is currently not open to traffic and the proposed subproject

will upgrade an existing pathway used by local people and the alignment has been approved by the

PPC.

Figure 2: Map of the subproject road

11. The Gio Linh – Cam Lo inter-districts road is formed on the basis of two existing roads (the access road to Ban Chua village, Cam Lo district and Xuan Hoa – Trang Rong road of Gio Linh

district constructed between 2001 and 2006) and lengthened to Quat Xa village Cam Thanh

Commune Cam Lo district by new bridge over the Hieu River, which will be constructed in the

subproject.

12. The existing road Xuan Hoa – Trang Rong of Gio Linh district has length 11,5km with different width of each section, from 3m to 7m. The road surface is mostly natural gravel or rugged

5

dirt with many deep and wide trenches. There are only approximate 800m with surface of cement

concrete still in good condition.

13. The existing road to Ban Chua village, Cam Tuyen commune has length 9,1km with width

of road from 2 m to 5m, of which around 1km has surface of cement concrete in good condition,

the remaining has surface of natural gravel or rugged dirt with many deep and wide trenches. This

road goes through the villages of Tan Hoa, Tan Lap, and Ban Chua in Cam Tuyen commune. At

the end of this road is section that currently not open to traffic, it is a trail with length 3.0km formed

by traveling of local people from Ban Chua village to Trang Rong village.

14. The lengthened section by new bridge over the Hieu River to Quat Xa village Cam Thanh

Commune is around 2,2km, of which, 2km with surface of cement concrete in good condition,

width 5,5m; the rest of the section has surface of rugged natural gravel.

15. Along of the existing road to Xuan Hoa – Trang Rong of Gio Linh district, on the two sides,

most area is rubber and melaleuca farms, interspersed a number of houses. Particularly section

from Km8 + 600 to Km11 + 500 has complex terrain, hill with height from medium to high,

melalueca forest on both sides. The route has 4 crossing points of streams. The population along

this route is quite sparse, there are only some small shops in the residential area of Trang Rong

village and the starting point of the road in Xuan Hoa village.

16. For the road to Ban Chua village, on both sides of the route are crops, rice fields and houses

of the people of Tan Hoa, Tan Lap, and Ban Chua village. The population along the road is more

crowded than the road to Trang Rong village but there are only some small shops. Along the road,

there are two crossing points of streams, the terrain of this route is relatively flat except 3.0km from

Ban Chua village to Trang Rong village has complex terrain, hill with height from medium to high,

melalueca forest around.

17. The lengthened section to Quat Xa village over the Hieu River, on both sides of the road

are crop and some houses as well as a primary school and health centre of Quat Xa village. This is

end point of the proposed road.

18. The proposed road of the subproject is basically located on the existing alignment of the

two existing roads and lengthened to Quat Xa village over the Hieu River therefore, environmental

and social aspect of two roads as well as lengthened section are also conditions of new road of the

subproject.

19. In DED period, there are two more points are determined that it is necessary to build bridges

instead of culvert at Km6+450,17 and spillway at Km8+524,35. At Km6+450,17, it is currently a

culvert over a small, narrow ditch with vegetable on its sides and melaleuca farm around. In dry

season, it is a negligible current of water on the ditch, however, in the rainy season, because of

narrow terrain, water way can be increased quicker and higher that leading to flood. The

construction of a new bridge will widen the drainage area compared to the present therefore the

water way will flow faster in the rainy season but will not affect the water way direction.

Construction new bridge is hardly affected to water way in dry season.

20. At Km8+524,35, it is currently a small stream with slow current of water and low water

level in dry season and existing a spillway with lower terrain compared with around area. This area

6

is also hills planted melaleuca. In the rainy season, water way increases over spillway and leading

to flood of this point. The construction of a new bridge over the stream will increase the flow rate

due to the expansion of the river bed at the point while direction of water way will not be changed.

Furthermore, during the construction time, excavation on the sides can result to obstruct the flow

and pile driving on the stream can lead to distribution of sediments into the water.

21. The road is proposed to be upgraded to category IV mountainous road in compliance with

Vietnamese Standard TCVN 4054-2005, with a roadway width of 7.5 m comprising a 5.5m wide

carriageway and shoulders of 2x1.0 = 2m. The total right-of-way (ROW) including side drainage

will generally be 14.5m. The proposed road is 22,810 km long.

- Design velocity: 40km/h

- Width of subgrade: 7.5m

- Width of pavement (carriage-way): 5.5m

- Width of shoulder: 2 x 1.0m

- Normal crossfall (%): 2%

- Max. Super elevation (%): 8%

- Pavement structure: Bitumen Surface Treatment

Figure 3 – Typical Straight Line Section

12. Bridges on the road: On the route, 6 new bridges will be designed for construction including

(i) a slab beam bridge at Km6+450,17; (ii) a slab beam bridge at Km8+524,35; (iii) a slab

7

beam bridge at Km11+521,78; (iv) a slab beam bridge at Km16+668.19 (v) a slab beam

bridge at Km17+811,98; (vi) a slab beam bridge at Km20+662,61; These bridges will be

designed with design flood frequency P = 4% for small bridges and P = 1% for medium

and large bridges, as following table.

13. Culverts on the route: consist of 118 culverts across the road, pipe culvert (52 items), box

culvert (18 items) and reinforced concrete culverts (48 items). They are built at locations

where drainage is required on roads and at cross-section of irrigation canals and ditches.

14. Others works along the road includes trenches with size 40x40x120(cm); reinforcing taluy

roofs with paving slabs in frequently flooded sections and embankment sections over hilly

terrain; retaining walls designed at steep slopes (> 50%) that cannot be covered with

conventional embankments; guardrail wall with reinforced concrete foundation.

a. Construction Material Sources

16. During the period of PPTA, the technical consultant, after consulting with the local authorities,

came up with some suitable quarries including 1 rock/stone quarry, 6 sand / soil sources which

meet the required capacity for the construction project and acceptable transport distance. In the

detailed design phase, the DED consultant conducted a survey and worked with local

authorities on the soil borrow pits as well as disposal sites which are suitable for construction

of sections on the road. The minutes of working on soil borrow pits are shown in Annex 4.

Specific information about the material sources is as follows:

Quarry source: All quarries potentially used for the subproject are checked legal status by DED

consultant and PMU. All related legal documents on these source are enclosed in Annexes.

17. The estimated volume of rock to be used for the subproject construction is 54,000 m3. Tan Lam

quarry: situated on the side of 9 Road at Km28+00 along road to Lao Bao, Cam Thanh

Commune, Cam Lo district with an area 8.3ha and a capacity of 3,000,000m3. It is about

10.6km from the quarry to the start point of the construction site and is served by an asphalt

road. This quarry are exploited by two companies: Joint venture of Thien Tan JSC and Tan

Hung JSC with license No 1190/QD-UBND dated 6/7/2012 (valid for 10 years); Joint Venture

Quang Tri Construction – Transportation JSC and Minh Huong Company Ltd with license No

1191/QD-UBND dated 6/7/2012 (valid for 10 years)

18. Soil borrow pit and gravel source: The estimated soil volume to be used for the subproject

construction is 190,000 m3. The volume of excavated soil that can be reused as fill soil is 81,000

m3. The rest will be purchased from the following borrow pits:

(i) Hill gravel quarry in Gio An 2: situated to the left of the provincial road 575B at Km6

Surface water resources and quality

23. The main water bodies in the subproject area are the Hieu River, and the Da Mai and Tan

Kim Reservoirs in Cam Lo district. As stated in the State of the Environment (SOE) 1 report

for Quang Tri, 2019, the surface water quality in the Hieu River was monitored but these

reservoirs was not and water quality of La La stream and other ravines was not also taken

sampling in the monitoring report in 2019 of Quang Tri province.

24. Monitoring program of Quang Tri province was taken place during whole the year and

sampling surface water and air quality every month. Locations for monitoring surface water

are 32 points in whole province, of which there are two points nearly the project area in Cam

Lo district. Ambient air quality are taken sampling at 25 points in the province and there are

two points in Cam Lo district nearly the subproject area.

25. Parameters were monitored: pH, F-, TSS, DO, BOD5, COD, NO3-N, NH4-N, PO4-P, Fe,

Total grease and oil, E.coli, Coliform.

27. As stated in State of Environment Report of Quang Tri 2019, the situation of parameters as

below:

28. pH: At all monitoring locations, the pH of river water is within the limit of column B1 of

QCVN 08, but there is a large variation according to space (locations) and time (months /

times of monitoring). The pH value at monitoring point of the hydrological stations Dau

Mau and Cau Duoi bridge is higher than the limit of column A2 in 2029 but is still under

the limit of Column A1.

29. NH4-N: NH4-N parameters at all monitoring locations are within the allowed limits of

column B1 of QCVN08-MT:2015/BNTMT. The location at Dau Mau hydrological station

has monitoring results of this parameter lower than that at Cau Duoi Bridge.

40. The dust in the air at most locations is within the permissible limits of QCVN 05. However,

the weather from March to September is hot and dry, the humidity in the air is low, so the

dust particles are weak adhesive, easily attracted to the air. So the dust is larger than other

times and exceeds the allowed limit of QCVN 05 in some locations. In particular, in

locations of main roads and large vehicle concentration areas such as the location of Cam

Lo town (K39), the dust concentration is approximately and over the permitted limit by 1.5

times in August.

41. Noise at most locations in 2019 is smaller than the permissible limit of QCVN 26 for normal

areas from 6am - 9pm. Particularly in some locations on the main roads such as Cam Lo

town (K39), Thien Tan rock Quarry area (K42), the noise regularly approximates and

exceeds the limit of QCVN 26 and fluctuates within about 60.3 - 76.3 dB (A)

42. Concentrations of toxic gases SO2, NO2, CO in 2019 at all monitoring locations are within

the permitted limits of QCVN 05, concentrations of NO2 fluctuate in the range of 8 - 74 µg

/ m³, SO2 fluctuates in the range < MDL (17 µg / m³) - 53 µg / m³, CO ranges from

20

land, the impact of road construction could cause forest fires or tree breakdown due to the

operation of machines and workers. In the operation phase, the new road will increase

accessibility to the forest as vehicles can flow easily.

Unexploded Ordnance

46. Along the subproject road, there is some possibility that UXO remains from

wartime, especially for Quang Tri, the province that suffered the most in the aftermath of the

war.

Therefore, PMU BIGG2 signed a contract with Enterprise 319.9 of 319 Corporation, Ministry

of Defense to detected and cleared UXO along the road. The clearing UXO was completed in

November 2019.

III. ANTICIPATED ENVIRONMENTAL IMPACT AND MITIGATION MEASURES

43. This section discusses the potential environmental impacts of the subproject and

identifies mitigation measures to minimize the impacts in all pre-construction, construction and

operation phases of the subproject.

44. The potential environmental impacts as well as the mitigation measures associated with

the pre-construction, construction and operational phases are assessed below. The criteria for

assessment are in line with ADB's Safeguard Policy Statement 2009 and the Government of

Viet Nam standards based on the Environmental Protection Law (2014). Where government

standards or guidelines have some kind of conflict with the ADB SPS, the ADB SPS will be

applied as the policy for the subproject implementation.

26

45. ADB safeguard policy statement (SPS) 2009 imposes safeguard requirements for all its

funded projects. The SPS 2009 clarifies the rationale, scope and contents of the environmental

assessment. It emphasizes environmental and social sustainability in progress of economic

growth and poverty reduction in Asia and the Pacific, with the following aims:

• Avoid adverse impacts of projects on the environment and affected people, where possible;

• Minimize/mitigate and/or compensate for adverse impacts on environment and affected people

when avoidance is not possible; and

• Help borrowers/clients to strengthen their safeguard systems and develop the capacity to

manage environmental and social risks

46. For environmental safeguards, the Subproject is initially categorized as ‘B’. A

subproject that is classified as category A on environmental safeguards would be ineligible as

a BIIG 2 subproject.

47. Due to the change in the detailed design compared to the FS such as widening the

roadbed by 1m, reducing the length of 500m, building 2 more bridges, the environmental

impacts are added at two points (Km6+450,17 and Km8+524,35) where two new bridges will be

built in comparison with the impact identified in the IEE report. Additional impacts take place

during the construction phase, and these impacts are flow rate of runoff and surface water

quality. They are assessed in moderate level and are the most significant change on impacts in

detailed design phase.

48. Potential impacts was identified in the original IEE report as well as additional impacts

are presented in the next section.

1. Potential Impacts Summary

Table 8. Summary of Potential Environmental Impacts

Issues Potential Impacts

Pre-construction Phase

Land acquisition and

resettlement The impact is mainly on the residential area along the road including

Hai Thai commune center in Gio Linh district; Tan Hiep and Tan

Hoa villages, Cam Tuyen commune and Quat Xa village in Cam

Thanh commune, Cam Lo district.

The subproject will affect approximate 160 households consist of

ethnic minority, poor and vulnerable households. The subproject

also affects perennial crop land, production forest land, annual crop

land and public land with total area is around 7,2ha.

Production forest land acquisition ( 5.4 ha) will reduce temporary

forest land areas of two districts but it does not have significant

impact to environment. Because, acquired forest area is scattered

along the existing road, almost of this forest land is planted

melaleuace which are periodically harvested by cutting down and

27


replaced by a new plantation. Therefore, the forest land acquisition

will not affect significant to surrounding environment as well as

erosion of soil.

Site clearance The impact is mainly on the residential area along the road including

Hai Thai commune center in Gio Linh district; Tan Hiep and Tan

Hoa villages, Cam Tuyen commune and Quat Xa village in Cam

Thanh commune, Cam Lo district

The subproject also affects land, tree, crop and structures of some

households, organizations and enterprises.

Disturbance of

Unexploded Ordnance

(UXO)

In November 2019, UXO was cleared by a military unit according

to contract with PMU.

Construction Phase

Disfiguration of landscape/

Tree and vegetation

removal

Construction work will involve some removal of trees along the

route, mainly along the 3.0 km section of new road and other trees

cultivated by people who live along the road. Land clearance at the

3.0 km section will involve minor alteration of the landscape. The

impacts will take place over 24 months of construction time.

Impact on crossing

streams or bridge

construction locations

The construction of new bridges may increase the flow rate in rainy

season due to expansion of space for drainage at that points although

direction of water way will not be changed. During the construction

time, excavation on the sides can result to obstruct the flow and pile

driving on the stream can lead to distribution of sediments into the

water. Furthermore, careless construction and poor handling of

materials at bridge sites can cause blockages and release of silt into

streams and other waterways. Runoff water during rain could bring

waste and soil into streams and the Hieu River, leading to a

temporary reduction in water quality and impact downstream user

of Hieu River including Cam Lo town and Dong Ha city.

All streams are natural flows and it is not to be used for living

activities or irrigation as well as aquaculture production except

some section of the Hieu River at downstream. Anyhow, the

implementation of subproject except impacting from construction

activities that are mentioned above, it does not affect to water uses.

Surface water pollution

The surface water quality of the subproject area could be degraded

due to silt runoff, release of chemicals used in construction and of

sanitary wastes from workers camps: (i) surface and subsurface

water resources may be contaminated by fuel and chemicals used in

construction, or by solid waste and effluent generated by the

kitchens and toilets at construction campsites; (ii) streams and the

Hieu River may subject to release of silt from borrow materials

28


piled near the construction area (iii) water in streams could be

temporary blocked during construction period at the crossing

positions.

The impacts will mainly on water bodies along the subproject road

and worker camps area, especially at crossing point with the Hieu

River as the main water source for Cam Lo Water Supply Factory

is Hieu River with the intake point located downstream of the

subproject area.

All streams are natural flows and it is not to be used for living

activities or irrigation as well as aquaculture production except

some section of the Hieu River at downstream so impact to water

use as mentioned above.

Impact related to material

transportation and Storage

Material transportation from Dong Ha city, communes of Cam Lo,

Gio Linh districts via NR No1, NR No9, Ho Chi Minh Trail and

some urban roads. This can affect to residence areas along these

roads by dust, noise, exhaust air from vehicles as well as risk of

traffic accidents. Besides, storage of construction material can cause

traffic jam, surface water dust pollution or community safety.

Impacts on dust and air

pollution

Earthworks and rock crushing activities will be the main sources of

dust.

Construction machines and vehicles will generate gaseous

emissions (NOx SOx, CO, CO2, etc.) when they are in operation.

Bitumen activity will also generate gas and odor.

These gaseous emissions, dust could cause respiratory problems for

residents who live along the subproject road likes Trang Rong, Ban

Chua, Quat Xa, Tan Hoa and Tan Lap villages.

Civil nuisance impact

including:

- noise, vibration,

- increased traffic,

- worker & public

accidents and safety

- Construction machines will also create noise during their

operation.

- Local people and people from other areas who travel on the

subproject road will be affected during the 24 month construction

period due to there is the only route for local people in several

villages of Hai Thai and Cam Tuyen to access the Ho Chi Minh road

and National Road No.9.

- Works and the public are at risk of accidents associated with

construction, particularly excavations, and operations involving

heavy machinery. Material transport and construction activities on

the existing road may create the risk of traffic safety and affect

houses and other structures on roadsides, particularly on the

residential areas along the road.

- The influx of construction workers can cause (i) a burden on local

public services like electricity and water supplies; (ii) risks of

transmission of diseases in the subproject area; (iii) conditions theat

29


favour thte spread of diseases such as sore eyes, cholera, flu and

respiratory problems; (iv) risks of social problems such as those

associated with gambling, drug use, prostitution, and violence. The

impacts would be on both workers and on the communities near the

construction sites in residential.

Erosion

Erosion can happened at slopes such as in 3.0km connected Trang

Rong and Ban Chua, and at crossing streams or bridge construction

locations. Erosion can affect to surface water quality or taluy, suface

of the road as well as vegetation around.

Solid/liquid wastes

Solid/liquid wastes from construction and worker activities can

bring about land contamination, surface water quality and

surounding environment of construction sites, worker camps.

Borrow pits and Spoil

Management

Borrow pits can lead to erosion, loss vegetation around or dust of

vehicles transportation, so all borrow pits will be used for the

subproject need to get permission of DONRE with measures to

reduce those impact.

Spoil/excavated soil can obstruct flows at crossing streams,

conterminate surface water, affect to traffic at residence area on the

road.

Site clean up

When construction work has been completed, any un-collected

waste or abandoned borrow pits pose potential hazards to people

and land as well as being unsightly.

Operation Phase

Increased traffic

The upgrading of the road is likely to increase the vehicle speed on

the road, leading to increased traffic congestion, traffic accidents.

2. Environmental Mitigation Plan

49. The anticipated environmental impacts and mitigation measures discussed in the

previous section are presented in Table 4. The table also shows responsibilities and

timeframe/schedule for implementation of mitigation measures and monitoring.

50. To ensure implementation of mitigation measures during construction, the EMP shall

be included in the tender and contract documents for civil works. Contractors’ conformity with

environmental contract procedures and specifications shall be regularly monitored by PMU

with assistance from CSC and results shall be reported semi-annually to ADB.

2. PMU will also inform Cam Tuyen, Cam Thanh, Gio An, Hai Thai

CPCs, local people and affected households, companies all information

related to the road construction in advance.

3. With approximate 5,4 ha production forestland acquisition, besides the

implementing the compensation in accordance with regulations, Quang

Tri PMU will implement afforestation/reforestation as defined in article

21, the Law on forestry 2017:

- Quang Tri PMU shall develop the plan of afforestation and reforestation

to summit to the Quang Tri PPC for approval. If the approved plan is not

implemented, Quang Tri PMU shall pay an amount to the Quang Tri forest

protection and development fund.

- The amount remitted into the Quang Tri Forest Protection and

Development Fund is equal to the afforestation/reforestation area

multiplies by the unit price per ha decided by Quang Tri PPC; Quang Tri

PPC shall decide to use the amount paid to such fund to carry out the

afforestation/ reforestation in the Quang Tri province.

- If the Quang Tri PPC fails to implement the afforestation/ reforestation

program within 12 months from the day on which the Quang Tri PMU

make full payment to the Quang Tri forest protection and development

fund, the payment shall be transferred to the national forest protection and

development fund in order to implement the afforestation/reforestation

program in other provinces.

4. The reforestation plan will monitored as regulation in Circular

13/2019/TT-BNNPTNT dated October 25, 2019: Regulation on

reforestation when changing the forest use purposes.

- According to Article 4 “Project owners shall not carry out reforestation

by themselves” at Clause 5: Project owner fulfill their obligation to

reforestation when they are informed by the provincial Forest Protection

and Development Fund about fulfilling the obligation of payment for

reforestation. Therefore, DPI Quang Tri (Project Owner of BIGG2

project) will submit confirmation of Forest Protection and Development

Fund Quang Tri as evidence for reforestation.
