Regional Conservation Agriculture Project Proposal in Degraded annual Cropping

Systems areas in South East Asia“USING CONSERVATION AGRICULTURE TO IMPROVE FARMERS INCOMES IN

DEGRADED AREAS

PROJECT PROPOSAL FOR LAO PDR, VIETNAM, CHINA (YUNAN)”

5th WCCA, Brisbane, Australia, September 26-29

Conservation Agriculture Network in South East Asia (CANSEA)


Outline

• Overview

• Experience and knowledge on CA in China, Laos and

Vietnam.

• CA context, Contribution to Generate Income of

Farmer

• Perspective of CA in Member`s Countries.

• Conclusion


In recent years, South East Asia agriculture has experienced profound and rapid changes. The joint process of deforestation, new land extension and agricultural intensification has often led to vast soil erosion and gradual soil exhaustion. CA has considerably improved situation.

Conservation Agriculture is an agro ecological approach associating rural development with

environmental preservation.

It is a generic concept integrating the whole agricultural practices & aiming both at viability

and sustainability of agriculture and environment protection.

Conclusi

on


Conservation Agriculture has to compete with the “Traders’ systems” offering the same level of mechanization performance and then attract private service providers who presently prefer make money with the plowing business.

Research will accompany the development by creating innovation to be tested with and for farmers.

Extension Services will perform a real support

Farmers’ groups will get official status authorizing access to credit facilities at normal rate…


We need supports to develop and disseminate CA according to the three regional priorities we have defined:- Intensify and diversify uplands farming systems;- Restoration of the fertility of degraded soils;- Improve Capacity Building of our Engineers and

Technicians.

We need to develop new scientific / development partnerships and new technical exchanges with organizations, institutions , private sectors

We need support from Donors to fund regional rural development programs based on CA to produce more while protecting our natural resources on this proposed theme
