- possible competition of trees with food crops for space, sunlight, moisture and nutrients which may reduce food crop yield;
- damage to food crop during tree harvest operation;
- potential of trees to serve as hosts to insect pests that are harmful to food crops; and.
What are the long term benefits of agroforestry?
Existing research suggests that
integrating trees on farms can prevent environmental degradation
, improve agricultural productivity, increase carbon sequestration, generate cleaner water, and support healthy soil and healthy ecosystems while providing stable incomes and other benefits to human welfare.
What are advantages of agroforestry?
Agroforestry practices
support agricultural production and help improve water quality and air quality, soil health, and wildlife habitat
. These working trees can also grow fiber, food, and energy.
What are the effects of agroforestry?
Agroforestry provides a number of environmental benefits as confirmed by scientific literature. The four major environmental benefits of agroforestry are
(1) climate change mitigation through carbon sequestration, (2) biodiversity conservation, (3) soil health enrichment
, and (4) air and water quality improvement.
What are the pros and cons of agroforestry?
- Soil fertility and closed nutrient cycles.
- Soil salinity control.
- Prevention of runoff and better water management.
- Stabilization of soils and microclimate.
- Low input of agrochemicals.
- Improvement of wildlife and pollinator habitat.
How does agroforestry help the economy?
Additionally, studies have shown that agroforestry
can improve and restore soil quality in degraded lands
. In countries that rely on small-scale farms as their main source of income, these practices could improve the standard of living through increased agricultural productivity while also reducing carbon emissions.
What is the concept of agroforestry?
Agroforestry is a
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.
How much does agroforestry cost?
Project Drawdown, a carbon solution tracking initiative, estimates a cost of
$26.8 billion
to implement agroforestry on an additional 19 million hectares globally — sequestering 9.3 billion gigatons of carbon and providing an estimated profit of $710 billion for farmers and investors by 2050.
What is the scope of agroforestry?
Agroforestry is a
potential approach to minimize unsustainable with drawals from forest
an instead promote production of fuel wood, fodder and timber in conjunction with Agricultural crops on non-forest land which provides vast scope.
What are the characteristics of agroforestry system?
- Tree species selected should not interfere with soil moisture.
- Tree species should not compete for plant nutrients.
- Tree species should not compete for sunlight.
- Tree species should have high survival rate and easy establishment.
Where is agroforestry used?
Agroforestry is the
intentional integration of trees and shrubs into crop and animal farming systems to create environmental, economic, and social benefits
. It has been practiced in the United States and around the world for centuries.
How do you manage agroforestry?

What is agroforestry and its importance?
agroforestry, cultivation and use of trees and shrubs with crops and livestock in agricultural systems. Agroforestry seeks
positive interactions between its components
, aiming to achieve a more ecologically diverse and socially productive output from the land than is possible through conventional agriculture.
What are the three types of agroforestry?
There are three basic types of Agroforestry systems viz:
Agrisilviculture (Crops + trees)
, silvopastoral (Pasture/animal + trees); and Agrosilvopastoral (crops + pasture + trees).
Why do we need to classify agroforestry?
The purpose of a general classification is
to identify different types of agroforestry and to group those that are similar
, thereby facilitating communication and the organized storage of information. A new scheme is proposed that uses the ‘practice’ rather than the ‘system’ as the unit of classification.
What are the scope of forest economics?
Traditionally, forest economics was concerned exclusively with the process of timber production. Today, however, its scope has expanded to take account of the multi-functional role that forests have in
delivering not only economic benefits to society but also environmental, social and cultural benefits
.
