1. Introduction
Agroforestry
Definitions
Agroforestry couldbe defined as a practice of raising both
tree and agricultural crops simultaneously in a given space
and time. In the Nepalese perspective agroforestry is an old
age practice. Recently, it has been receiving considerable
attention due to the evidence that trees and agricultural crops
could be managed simultaneously and guaranteed and
sustainability of agricultural system. (Nepal forestry Handbook,
2067 B. S.)

Cont’d
Agroforestry is aland use management system in which
trees or shrubs are grown around crops or pastureland. It
combined agricultural and forestry technologies to create
more and diverse, productive, profitable, healthy and
sustainable land-use systems. (Encyclopedia)
5.
Cont’d
Agroforestry isa collective name for land-use systems and
technologies where woody perennials (trees, shrubs, palms,
bamboos, etc.) are deliberately used on the same land-
management units as agricultural crops and/or animals, in
some form of spatial arrangement or temporal sequence. In
agroforestry systems there are both ecological and
economical interactions between the different components
(Lundgren and Raintree, 1982).
6.
Cont’d
This definitionimplies that:
agroforestry normally involves two or more species of plants
(or plants and animals), at least one of which is a woody
perennial;
an agroforestry system always has two or more outputs;
the cycle of an agroforestry system is always more than one
year; and
even the simplest agroforestry system is more complex,
ecologically (structurally and functionally) and economically,
than a monocropping system.
Cont’d
The theoreticalbase for agroforestry comes from ecology via
agroecology from this perspective agroforestry is one of the
three land-use science.The two are agriculture and forestry.

2. Importance andapplications
Benefits
Ecoscaping-Agroforestry can be advantageous over
conventional and forest production methods. They can offer
increased productivity, economic benefits, and more diversity in
the ecological goods and services provided.
Biodiversity in agroforestry systems in typically higher than in
conventional agricultural systems.With two or more interacting
plant species in a given area. It creates a more complex habitat
that can support a wider variety of birds, and other animals.
Depending upon the application, impacts of agroforestry can
incude

Cont’d
Reducing povertythrough increased production of wood and
other products
Contributing to food security by restoring the soil fertility for
food crops
Cleaner water through reduced nutrient and soil runoff
Countering global warming and the risk of hunger by increasing
the number of drought-resistant trees and the subsequent
production of fruit, nuts and edible oils

Home garden
( e.g. Sisso with banana, pine apple, turmeric etc. in terai and kutmiro, khanyu,
gogan+vegetable in hilly areas)
Trees in and around agricultural fields in rain fed areas (khanyu, kavro,
kutmiro trees in the border of terraces and maize, millets, pulses etc in the
center of the border trees)
Woodlots (on the top of the agricultural field and on the bank of river to
protect from soil erosion in the hilly areas)
Commercial crops under tree (e.g. tea under siris in the eastern terai and
cardamom under utis in the eastern hilly areas)
Intercropping with horticultural crops (mango +agricultural crops in terai)
Silvofishery system (Sisso, Ipil-Ipil plants raise on the bank of fish ponds )

Group (LFUG)
International recognition of Leasehold Forestry in
short time
Learning for the private forestry
65.
10.Possible Solutions
Making policy,laws and necessary directives for the
development of leasehold forestry
Agroforestry Programs should be given both Forest
and Agriculture ministry
Frequent co-ordination should be done between Forest
ministry and agriculture ministry and also at the
different levels of the corresponding departments
Planning should be done jointly at the district level
66.
Cont’d
Agroforestry program shouldgiven to private farmers
too
Action researches should be conducted at the field
level
Necessary technologies/trainings should be provided
to local level staffs and also to private farmers by
concerning organizations according to their need
Appropriate laws and policies should be prepared for
the groups and private farmers to sell their products in
the market easily
67.
Cont’d
If possible,financial supports should be provided to
the farmers that they can develop their enterprise
68.
11. Conclusion
Agroforestry –This system can be advantageous over
conventional agricultural and forest production
methods. They can offer increased productivity,
economic benefits and more diversity in the ecological
goods and services provided. This system is typically
higher than conventional agricultural systems with two
or more interacting plant species in a given land area.
This system very suitable in the different physiographic
zones of Nepal for the improvement of physical
condition as well as well being of all people.

Question 1
What isthe role of agroforestry in food security biodiversity
conservation in Nepal ? Identify major agroforestry systems
in the hills & mountains and key contribution in the
livelihood important
Ans.Agroforestry system increases biodiversity as of:
Forest crops
Agricultural crops
Horticultural crops
Animal husbandry
Ecosystem services
77.
cont’d
Increased forest areasprovide water, nutrients to
agricultural crops consequence of it, increases in
the production of agricultural crops
Improve the condition of soil
Great no of cattle contribute big amount of
manure
Leguminous trees increase nitrogen in the soil
Leaves & foliages of trees increase green manure
Trees provide edible fruits
Forest trees improve the environmental condition
consequence of it, rainfall intensity increases
78.
Cont’d
Due toimprovement of agroforestry increases
in the production of the land
More production more security of food
A. Major agroforestry systems in the hills
In context of Nepal, most of the agroforestry
systems are conventional types
Few systems are given below
1. In eastern Nepal (e. g. siris as a upper storey
and tea is in under storey) can be seen in Ilam,
Panchthar, Dhankuta, Terhathum districts.

Question 2
What arethe problem & prospects of agroforestry in present political scenario
in Nepal ? Elaborate your answer with Sagarnath &Tamagadhi forest plantation
.
Ans.
History of Sagarnath and Tamagadhi plantation
1.Sagarnath Forest Development Committee
Started in aiming to supply fuelwood in kathmandu valley
More than 10,000.00 ha.
Degraded mixed forest main sp was sal
Taungya System had adopted
Main spp. Eucalyptus camadulensis and Eucalyptus tereticornis
82.
Cont’d
Coppice system isused
More than 2500 ha. Areas are under the
encroachment
Tried many times to remove them from there
by the District forest Office Sarlahi and
Sagarnath office in co-ordination with CDO and
police force however, no any achievement
83.
History of TamagadhiPlantation Area
Started since, 1972
Encroachers started to settle there illegally
GoN decided to settle there and introduced
TAUNGYA system
Planted major forest spp. Teak and sissoo and
agricultural crops are mustard and pulses
Now there is no any system
People are still settling there
They are removing trees and haphazard thinning
for their agricultural crops
Condition of the forest is deteriorating day by day
Cont’d
Problems
Only DFOand Sagarnath project staffs feel it is the big
problem
Other members of the committee do not take it
seriously
Encroachers are the voters of the local party members
Local leaders do not take interest to evacuate them
from the project area
Local administration do not take the burden seriously
It is not functioning well even then the cabinet is not
amending the present structure
86.
Cont’d
Present Political scenario
No political commitment by the ministry
Cabinet’s decisions are not implement in the field
A committee is already formed in the chairmanship of CDO and other
members are as follows
1) CDO…………………………………………………………. .Co-ordinator
2) Local Development officer (DDC)…………………………Member
3) District police officer Chief (Nepal Police)………........Member
4) District Police officer Chief (Armed Police Force)……Member
5) District Land Revenue Officer (Malpot Office)………..Member
6) District Cadastral Survey officer (Napiko Office)…….Member
7) Major 5 Parties political leaders at local level ………. Member
8) Local journalist……………………………………………….. ..Member
9) District Forest Officer (District Forest office)……….. Secretary
87.
Cont’d
In present scenario,the encroachment evacuate
committee is not functioning well
All the committee members are not realizing
their responsibilities as forest organization
No commitment of the political leaders to take it
seriously
Political instability
Different political parties have different ideology
and do not recognize other parties ideology
consequent of it, cabinet’s decisions are not
implemented
