FRAMEWORK FOR THE DEVELOPMENT OF JATROPHA CURCAS

FOR BIODIESEL

OBJECTIVES

to develop and determine the technical and

financial feasibility of production system models

that integrate Jatropha curcas in agroforestry,

plantation forestry, and agricultural system, as

well as in the rehabilitation of degraded lands

without sacrificing overall farm productivity and

income and at the same time providing

environmental services.

To design and evaluate agroforestry and agricultural

systems for smallholder farmers in the Philippines that

incorporate Jatropha curcas;

To determine the potential of Jatropha curcas in the

revegetation and/or rehabilitation of abandoned mine

sites and lahar devastated areas; and;

To develop appropriate silvicultural and agronomic

practices for Jatropha curcas integrated in various

agroforestry and agricultural production systems for

smallholder farmers;

OBJECTIVES

COMPONENTS

• Ex-Ante Assessment of the Production, Promotion

and Development of Jatropha curcas for Biofuel

• Integrating Jatropha curcas in Developing

Sustainable Agroforestry Systems in the Philippines

• Development of Farming Systems Model Integrating

Jatropha curcas in various Agricultural Systems

• Plantation Establishment of Jatropha curcas in

Lahar-laden and other Marginal Areas in Central

• Establishment of Mychorrizal Jatropha Plantations

for Biofuel and as Rehabilitation crop in Abandoned

better due to

excessive rains

A Socio-economic and Policy Analysis on the

Promotion and Development of Jatropha as a

Viable Biofuel Feedstock

• LGU-led Jatropha production, promotion and

development project

• Private-led Jatropha production, promotion and

development project

Modes of Jatropha Project Implementation :

Schemes for Government Lands

Joint Venture Agreement with the PhilForest Corp for public

Production/Growership Contract

Nursery Establishment: seedlings/planting materials are

sourced by the LGU in their regular budget allotment; labor

requirements like nursery maintenance are provided by the

regular staff JPMO while harder activities are contracted

out on a pakyaw or per unit basis

All other inputs like fertilizer, herbicides and other

chemicals are provided by the JPMO.

LGU-led Jatropha production, promotion

and development project

Production/Growership Contract

Plantation Establishment:

Jatropha outplantings and

maintenance are contracted on a

per hectare basis

LGU-led Jatropha production, promotion and

development project

Schemes for private land

Lease Agreement

• LGU leased the land of individual farmer through a

MOA. From nursery up to plantation establishment

and development, planting materials and all other

inputs are provided by the LGU for one production

period.

• Starting from the first harvest, the farmer will start

amortizing the production cost payable in three years:

“Plant Now Pay Later”

• In this scheme, the farmers are guaranteed with a

market and fair price for their Jatropha seeds.

LGU-led Jatropha production, promotion

Schemes

Leased Agreement - private investor lease a parcel of

land at an agreed price and for a fixed period of time;

developed the Jatropha plantation through hired labor

Private-led Jatropha production, promotion

Joint Venture Agreement

MOA; 10 years

Expenses for Jatropha plantation development

and maintenance are shouldered by the investor

Proceeds of yearly production will be shared as

follows: 30% amortization for development; 35%

land owner; and 35% investor share

After loan payment, proceeds will be shared

equally

Upon expiration of the contract, the land together

with the improvements will be turned-over to the

Private-led Jatropha production, promotion

Private-led Jatropha production, promotion and

development project

Schemes

Lease Agreement of public(upland,untenured, and

open access) lands

Lease contract between the private investor and

the PhilForest Corp; issued a tenurial instrument

called EPIL Agreement ( Economic Productivity out

of Idle Lands) which has a tenure of 25 years

renewable for another 25 years, when appropriate.

Some perceptions

There is positive/favorable attitude of both the farmers and project implementers in venturing into Jatrophaproduction.

There is positive perception; farmers/project implementers are optimistic that Jatropha could help improve the lives and well-being of those involved in the project.

Income derived from Jatropha although representing only a small percentage of the household’s aggregate income has a great potential to alleviate poverty in the countryside.

Jatropha projects has also great employment potential especially for women.

Will lands devoted for food production be

converted into Jatropha production?

According to Jatropha farmers/planters:

47 % said No; lands for food crop production will not be

converted into Jatropha production

16% said Yes; 37 % said they do not know.

There will be no conversion of lands in favor of Jatropha

production due to the following reasons:

Only idle/vacant lands will be used; if area is suited for

food crops, they will not shift to Jatropha

Food crops are still their priority because food crops can

be readily sold and can answer daily food needs of the

family; Jatropha can be intercropped

Will lands devoted for food production be

converted into Jatropha production?

According to Jatropha project implementers:

67% said No; farm lands will not be converted to Jatropha

production.

27% said Yes; there is a possibility that farm lands will be

converted to Jatropha production

Farm lands devoted to food production will not be diverted

to Jatropha production because of the following:

Jatropha will only be planted in areas unproductive

to food crops and idle lands

Farmers are used to planting food crops hence

planting these crops will always be given top priority

SUMMARY

• monocropping of jatropha is not a viable alternative

for smallholders.

• intercropping Jatropha with agricultural crops such

as sweet potato , turmeric, and other shade tolerant

crops has potential

• the promise of the Jatropha-coconut planting,

another crop combination for the promotion of

bioenergy cropping systems remains to be seen.

• underground biodiversity of Jatropha is rich. It even

stimulates the VAM fungi sporulation and root

colonization under field conditions.

• In marginal areas such as lahar-laden soil

conditions, Jatropha plants survived, but needs

fertilizer to stimulate growth. Similar pests and

diseases were observed affecting the plant in its

seedling stage.

•In abandoned mine sites, application of lime and VAM

improved the performance of Jatropha and forest

trees. Diversity of microorganism is also promoted

with diversification

•Heavy metal concentrations, could be translocated in

different parts of the Jatropha plant, i.e. roots and

stem. With this, lime and Mykovam were applied to

reduce its effect.

•Ex Ante analysis of the prospects of Jatropha

indicated that planting of Jatropha will yield

promising results through providing employment to

rural areas.

•Analysis also showed that Jatropha production will

not threaten food security.

• much concern is raised in terms of its marketing

and skeptical attitude of some producers in terms

of its profitability.

• Food, Feed, Fuel Complementarity

• Research and development

• Land use and conversion

• Income and employment

• Government intervention and energy independence

• Business models and Equity

• Jatropha beyond biofuels
