Covering vegetables with bamboo nets
With the change in temperature condition, incidence of pest and insect infestation also increases. Vegetable fields are routinely devastated by insects and extended drought conditions. Small holding farmers can combat this issue through simple technique of using bamboo net barriers. |

Cultivating before rainy season
Adjustment of planting date or changing in cropping calendar is important to minimize the effect of temperature and sustaining the yield. Planting before rainy season will allow more effective use of soil moisture received from rainwater. |
|
Mulching
Mulching is cultural practice often recommended in the cultivation of vegetables and mulch is a protective covering usually of leaves or straws placed around the plants. Spreading dry leaves over crops control the water losses due to transpiration. |

Placing sticks to act as support to prevent crops from falling down due to heavy rainfall.
Heavy and unpredicted rainfall, strong wind and other adverse weather condition could be resultant of expected climate change. Simple and cultural way to save the standing crop from falling down due to heavy rainfall would be placing sticks for the support. |

Residual moisture
In some soils in arid regions with short rainy seasons, crops are planted near the end of the rainy season and even after rains have ceased in order to take advantage of moisture stored in the soil. Tepary beans are produced using this principle. Melons are often used as such crops. |
|
Planting density
Limited moisture dictates the necessity for wider row spacing and lower rates of seeding (by one-half to two-thirds) than are used in moisture abundant areas. The resulting reduced plant population provides more moisture and nutrients per plant and thus enhances the possibility of the crop reaching maturity before the supplies are exhausted. |

Planting of drought resistant varieties of crops
Emphasis on more drought resistant crops in drought-prone areas could help in reducing vulnerability to climate change. For example,

Direct seeded rice cultivation:
In direct seeded rice cultivation, raising of nursery for transplantation is done away with. In case of delay in monsoon or shortage of water, it gives the farmer flexibility to take up direct sowing of paddy with a suitable duration variety to fit into the left over season. Direct sown rice consumes relatively less water compared to transplanted flooded rice. Energy demand for pumping of irrigation water is also less. |
|
Integrated farming systems:
In areas prone to floods and extreme weather events monocropping is generally practiced. In these vulnerable areas, dependence on single farm enterprises by farmers is risky as they have limited resilience to cope with climatic constraints. Integrated farming systems approach involves use of outputs of one enterprise component as inputs for other related enterprises wherever feasible, for example, cattle dung mixed with crop residues and farm waste can be converted in to nutrient-rich vermi-compost. |
|
Improved irrigation efficiency:
Success of climate change adaptation depends on availability of fresh water in drought-prone areas. As water becomes a limiting factor, improved irrigation efficiency will become an important adaptation tool, especially in dry season, because irrigation practices for dry areas are water intensive. |
