It is generally observed that drought affects various stages of all the crops growth cycles and it was also more advantageous to plant early in the south west and north east rainfall regions but a month later after rainfall onset in the south east rainfall region since the off season rains seem to favour late planting in the last region. Drought stress in the early planted crops in the south east frequently occurs in March interfering with the establishment stages but also the peak phases of some crops as well. Later planting foregoes these drought stress problems with relatively few if any stress problems occurring. In the north east drought may affect the peak and sometimes pre and post peak phases of late planted crops although cassava and potatoes are virtually unaffected by any drought stress in this rainfall region. Late planted long maturing crop varieties perform better than short maturing crops. In the southwest, drought stress is worse in the latter planted crops as compared with early planted ones although both plantings may suffer drought stress from the pre peak phase all the way to the end of the season. Cassava and potatoes have better chances of survival in this rainfall region than any of the other seven crops investigated. These inherent establishment phase stress intensities may however be avoided by planting later in the season. In the south west more crops would suffer intense drought stress of the order of some 40 mm of rainfall deficiency from the pre-peak to post-peak phases.
In The Gambia, over-dependence on rain-fed agriculture for livelihoods increases farmers’ vulnerability to climate change. For farmers to increase crop production there is the need for them to be aware of climate change and how they can sustainably respond to its variability.

Despite the efforts of both government and non – governmental organizations on recommendation of climate change adaptation strategies to crop farmers, which were aimed at reducing its adverse effects on crop yields, the demand for food is still at an alarming rate, because of the ever increasing population in Nigeria.
The Hydro-morphological regime of Dhaka city lies on several connected rivers and channels with extensive inundates flood plain in both side of the river areas. The current study exposed the Hydro-morphological condition and challenges of water resources development for Turag River.
The current level of poverty in Nigeria is disturbing and climate change impends food security and increases poverty indirectly and directly on individuals or households.
