(SOM). Biochar addition to soil can provide a potential sink for C. From
a climate change mitigation perspective, biochar needs to be considered
in combination with other mitigation strategies and cannot be seen as an
alternative to reducing emissions of greenhouse gases. From a soil conser-
vation perspective, biochar may be part of a wider package of established
strategies.
Home gardening in the tropics imitate nature through integrating trees
(fruit-bearing trees and fodder trees) and other perennials with a mixture
of other crops. Home gardening is prevalent in many areas in India as
mitigation and adaptation strategy to climate change.

RAINFED HORTICULTURE
In rainfed regions, horticulture helps in diversification, risk mitigation,
value addition and enhancing farm income. With the introduction of Na-
tional Horticulture Mission, there has been a sharp increase in area under
horticulture in rainfed regions. Rainfed eco systems with 700 mm or more
annual rainfall have relatively better opportunity for horticulture. The pro-
duction and productivity of rainfed horticulture mainly depends on the
quantum and distribution of rainfall. However, year-to-year productivity
is also influenced by a number of climate factors like temperature, humid-
ity and extreme weather events like cyclones, floods, hail storms, heat
wave and cold wave. Rainfed horticulture also plays a stabilizing role in
providing fodder for livestock when practiced as horti-pastoral system. In
India, a number of horti-pastoral systems have been recommended which
have demonstrated their usefulness both in terms of nutritional security
amla and tamarind are some of the important horticulture crops grown in
semiarid and dry sub humid regions with supplemental irrigation. These
crops are subjected to high climatic variability particularly the rainfall and
temperature in a geographical location.
