Section 1. Context of the best practice: frame conditions (natural and human environment)

Short description of the best practice

To provide models for better use of sandy areas through sand use planning introduction via different schemes of agro-forsstry; agro-forestry-irrigation; Silvo-pastoral; Silvo-Fifhery


Central Coastal Region of Vietnam

If the location has well defined boundaries, specify its extension in hectares:


Estimated population living in the location:


Brief description of the natural environment within the specified location.

Along the coast but with sand dunes and hills
White and Yellow Sand
Very hot in summer (40-42oC), on open sand dune sometimes reach to 65oC
Temperature variation between noon and noght is between 10-15oC
Rainfall: very low, in some areas only 500-700 mm/year
Evaporation: vey high, double higher that the average one|

Prevailing socio-economic conditions of those living in the location and/or nearby

300-400 USD/year
Not very much interest because of low productivity
Poor crop production and fishery

On the basis of which criteria and/or indicator(s) (not related to The Strategy) the proposed practice and corresponding technology has been considered as 'best'?

- Good techniques
- Use of multi-sector approach
- Use traditional knowlegde and knowhow
- Posibility for wide replication to other areas

Section 2. Problems addressed (direct and indirect causes) and objectives of the best practice

Main problems addressed by the best practice

Sand movement to attack to villages, rice field, roads and garden
Unproductive sandy area |

Outline specific land degradation problems addressed by the best practice

Very dry and infertile sandy area

Specify the objectives of the best practice

Fix sand dune movement
Improve livelihood of people living in affected area

Section 3. Activities

Brief description of main activities, by objective

Plant forest to fix sand dune movement
Use different models to generate income sources

Short description and technical specifications of the technology

Establish forest belts to improve micro-climate and soil conditions with suitable tree species
4-5 years later, plant food crops, vegetables and build houses, start carrying out livestock production and fishery activities|

Section 4. Institutions/actors involved (collaboration, participation, role of stakeholders)

Name and address of the institution developing the technology

Dr. Vo Dai Hai, FSIV|Dong Ngac, Tu Liem, Hanoi, Vietnam

Was the technology developed in partnership?


List the partners:

Local people
Local authority
Scientists of FSIV and other research institues on irrigation, agriculture, fishery

Specify the framework within which the technology was promoted

  • National initiative – government-led
  • Programme/project-based initiative

Was the participation of local stakeholders, including CSOs, fostered in the development of the technology?


List local stakeholders involved:

Local people
Technical staff at local level
Local experts

For the stakeholders listed above, specify their role in the design, introduction, use and maintenance of the technology, if any.

They are the key partner and beneficiary of the new technology

Was the population living in the location and/or nearby involved in the development of the technology?


By means of what?
  • Consultation
  • Other (please specify)

Sharing experience, knowledge
Providing information and lessons learnt


Section 5. Contribution to impact

Describe on-site impacts (the major two impacts by category)

More water for daily live and production, less hot micro-climate conditions, no sand movement,|
Improve living conditions of local people by providing more income sources
Providing better living environment, more water for daily live and production, less hot micro-climate conditions, no sand movement, better conditions for building houses in sandy area|
More stable living area and better conditions for community activities

Describe the major two off-site (i.e. not occurring in the location but in the surrounding areas) impacts

Better transportation due to less sand dune movement to roads
Better living conditions for neibouring villages due to sand movement

Impact on biodiversity and climate change

Explain the reasons:

More species come back to the area, like rabbit, mushrooms, when the living conditions are better|
Forest development and better use of land by suitable technology can reduce emission and promote better carbon stock enhancement
Less hot weather and more water in

Has a cost-benefit analysis been carried out?

In your opinion, the best practice/technology you have proposed can be replicated, although with some level of adaptation, elsewhere?


At which level?
  • Local
  • Sub-national
  • National
  • Subregional
  • Regional
  • International

Section 7. Lessons learned

Related to human resources

Traditional knowledge and experience of local people are very helpful for any research and study on new technology applied in the local areas

Related to financial aspects

Small fundding may be enough if there is a clear potential benefits that the research can bring to people because the promissing results can encourage people to contribute their labour force and local material to the research and actively maintain these afterward.

Related to technical aspects

There should be the integration of traditional biological measures and modern technologies.
