Executive Institute
 Academy of forest science (AFS)
During the last few decades, Academy of Forest Science (AFS) have
invested many efforts in developing agro-forestry (AF), as sustainable
forest management, in resulting many successes including selection of
high value AF species, identification of best crop-tree models,
protecting soil erosion, increasing biodiversity and etc. Academy of
Forest Science is developing “Forest Carbon Offset” program in AF in
order to overcome rural people’s economic difficult and contribute to
climate change. To make the program more reliable and transparent,
AFS must identify criteria and lists of forest carbon sequestration
according to species, density, regions and ages for registration,
verification, and validation in “Forest Carbon Offset” program, and
establish theoretical and practical base.
AFS is also studying about short-rotation woody bio-fuels and
integrated pest management to protect damage of forest.

 No separation of characters in
seed reproduction, easy cutting
and cultivation
 Not so high demand for soil
quality
 High resistance to cold weather
and to pest

temperature, cultivated in all eco-zones with
annual rainfall of 500mm, and 1 550℃ of
accumulated growth temperature

Advantage of Aronia AF
 Low-level competition
against crop for light and
nutrition
 High fruit value (5~7kg/plant
at 8th year)
 15~20 years of AF duration
 Low cultivation cost
 Rapid effect in prevention of
land loss at sloping lands
Recommendations from Research
 Aronia AF can serve as a way-out for long-term food
security bare sloping lands at densely-populated areas.
 Aronia AF enables mixed AF for its high rooting rate,
high planting density and rapid land protection effect.
(pinut＋aronia＋soybean).
 Aronia AF is an efficient AF type with rapid and high
fruit value and larger crop cultivation duration.
 Aronia AF should be coincided with knowledge
transfer for cultivation to local population.
Bio-ecological Characters of Chestnut
 Broad- and falling-leaved arbor
growing higher than 5m
 Fruit production between 4th and
10th year with safe fruit production
until 20th year.
 Large scale reproduction through
grafting
 Chestut, as an indegenuos species,
has dry-tolerance and well growth
even on barren land
Utility of Chestnut
 Delicious nutritional food
 Timber used for stock, ship-build
ing, tie plate for bridge and whee
l for hardness and resistance to
moisture and decomposition
 Usage in forestation of bare mou
ntains for high vitality in draugh
t and poor fertility
Scope of Distribution and
Cultivation of Chestnut
 As a native species, chestnut has low demands
for soil fertility and climatic conditions, which
enables the plant to grow in every eco-zone
except those higher than 800m above sea level.
 Chestnut AF is under cultivation trials at Unjon
County of North Pyongan Province and Wonsan
City of Kangwon Province and has been
introduced into project sites in North Hwanghae
Province.
Advantage of Chestnut AF
 High fruit value (2t/ha at 8th
year)
 7~10 years of AF duration
 Low cultivation cost
 Rapid effect for land loss
prevention at sloping lands
 Traditional cultivation
techniques mastered by
local population
Recommendations from research
 Chestnut AF can serve as a way-out to short-term food
security in bare sloping lands with high population density
and to long-term income increase.
 Chestnut AF can improve livelihood of local people
without huge investment since chestnut is a species
easily cultivated at mountainous areas.
 Chestnut AF is an easily applicable AF type for chestnut
has been cultivated traditionally.
 Chestnut AF is promoted by national policy of expanding
chestnut forest.

el.

cultivation trials at Wonsan City of
Kangwon Province and Suan County
of Hwanghae Province and has been
introduced into project sites in North
Hwanghae Province.
Recommendations from research
 Japanese larch AF can serve as a way-out to afforest bare
sloping land with contribution to long-term food security.
 Japanese larch AF can serve as a way-out for short-term
food security at felled forest or reforested areas.
 Japanese larch AF enables AF at areas with high soil erosion
for the plant has rapid land protection effect with its high
rooting rate and high planting density.
 In Japanese larch AF, when the canopy disables AF, multi
