2. Introduction
Poverty alleviation is the overarching goal in Lao
PDR’s five-year National Socio-Economic
Development Plan (NSEDP)
Availability of forest and land resources and cheap
labour have attracted large flows of foreign
investments into Lao PDR, particularly to the
agricultural sector
Maize and rubber are two of the more important
commercial crops in terms of land area
In 2010, maize expanded rapidly and exceeded
200,000 ha, while rubber area reached 250,000 ha
Land expansion is at the expense of forests and
smallholder mixed farming systems, leading to
degradation of soil and water resources

4. Objective
Generate information on the costs and benefits of
four land use systems, (NTFP collection, and
plantation for upland rice, maize and rubber)
Determine how high REDD+ incentives would need
to be in order to solicit a positive response from
farming households do not convert forests).
Compare the costs and benefits of land use on
how commercialization of agriculture can support
the NSEDP goals of rural poverty alleviation and
sustainable development.

5. Analytical framework
Household surveys in 3 districts of Oudomxay
province
Four land uses are assessed: Rubber (smallholder
plantation and contract farming systems), Maize,
Upland Rice, Forest/NTFP
REDD+ costs and revenues are considered only
for the Forest/NTFP land use
Costs of health impacts caused by environmental
degradation and over use of pesticides and
herbicides are included
The study assumes a time frame of 30 years,
which is the normal cycle for a rubber plantation
5
6. Analytical framework
A simple cost-benefit framework is used to estimate Net
present values (NPV) derived from a 1 hectare from
each land use practiced
The classical optimal utility model, the household’s
decision to deforest for another land use, d, depend on:
Where if d=0, households will not deforest; and if d=1,
households will deforest
6
7. Results of the study
Rubber plantation is the most profitable land use
option
Land use systems of upland swidden rice farming,
maize plantation and forest/NTFP generate losses
over the long-term
The opportunity cost of labor is the largest share of
incurred costs, but this is not factored into the
farmer’s rational decision-making process
7
8. Research results (cont.)
NPVrubber > NPVf, REDD for all the PCO2 scenarios,
indicating the rational farmer will decide to convert
forest lands into rubber plantations,
REDD+ incentive would need to be at least US$ 15
per ton CO2-1 (generating NPV of USD 665 and
BCR of 2.61) in order to compete with a 2+3 rubber
contract farm.

9. Policy oriented recommendations
The expansion and development of maize and
rubber plantations has to be accompanied with
specific environmental mitigation measures to
prevent degradation of soil and water resources.
The REDD+ incentives, when provided at
appropriate levels, can be an effective mechanism
to support forest conservation and ecosystem
service maintenance
Decisions on conversion of forests and
development of commercial agriculture should be
based on proper cost-benefit analyses that
integrates environmental costs and enables
comparison between land use options
9
10. Conclusion
Maize and rubber plantation has improved cash
incomes for the household, but they exposed the
area to environmental risks (soil depletion and
water contamination)
Upland rice swiddens and collection of NTFPs are
currently sustainable land uses, but are
increasingly vulnerable under the pressure of
expanding maize and rubber plantations into old
fallow and secondary forests.
The REDD+ incentive can be an important
mechanism to compensate farmers for maintaining
ecosystem services and forgoing alternative
agriculture land use.
