Types of Agroforestry1. Agroforests: combinations of perennial

species on arable land2. Home gardens with perennials3. Woodlots or farm forests4. Trees on field and farm boundaries5. Sylvopastoral systems: Trees in pastures6. EverGreen Agriculture: Trees

intercropped with field crops7. Productive landscape systems

What is EverGreen Agriculture?

A form of more intensive farming that integrates trees with annual crops.

EverGreen farming systems are often ‘double- story’ systems that feature both perennial and annual species (food crops and trees).

Types of EverGreen Agriculture

1. Farmer-Managed Natural Regeneration (FMNR) on cropland

2. Conservation agriculture with trees (CAWT)

3. Conventional agriculture interplanted with trees

Classes of Trees in EverGreen Agriculture

• Trees providing direct cash or nutritional benefits

For example:

Timber - Grevillea,

Oil – Shea

Fruits – Uapaca

• Trees providing indirect benefits

For example:

Fertilizer trees – Faidherbia, Gliricidia

Fodder trees -- Caliandra

EverGreen Agriculture: Opportunities1. Policy, Technical, and Scaling-up Support to

Countries and Communities of Nations that are implementing or launching evergreen agriculture scaling-up programmes

2. Support mainstreaming of evergreen agriculture into the community of UN Organizations and Development Banks, building support for greater impact

UNCCD, IFAD, World Bank, GEF, FAO, UNEP

3. Support mainstreaming of evergreen agriculture into regional and subregional organizations

5. Support scientific communities and exchanges to help build research partnerships to tackle key issues and overcome barriers to scaling-up

Take home messages• A fresh low-cost approach to land

regeneration and food security has taken root in Africa, and is spreading across the continent.

• Millions of smallholders are adopting effective low cost land regeneration methods

• Poor households should be targeted over large areas to end hunger in Africa

• Many nations are implementing or launching national scaling-up programmes

• An EverGreen Agriculture Network could accelerate the process of widespread adoption
