If you are a PG student and wants to conduct research for your degree program, you will have to be specific. You need to be clear for the area of specialization which you want to attain. But it is always good and logical if you conduct research on an area which addresses some issue or problem being faced by the farmers or industry of your region/agro-climatic zone, i am sure you will be appreciated more, if done like this.

First, you have to specify the plant species you want to work on. Then you have to investigate with the producers in the study area to see how much water is being used on the plant. Next, you have to follow the crop with amounts of water below and above the amounts used by growers and monitor plant growth parameters as well as the evolution of pest populations in different cases. Theses essays in order to see the impact of the change in the water status of the plant on the growth parameters of the plant and on evolution of its enemies populations.

it depends, you want a regional status, or interested in a global prospective. in case, you want to solve your regional agro-ecological zone problems. you have to be specific to that. but in both cases, you should be holistic in your approach and consider all aspects. For global prospective, you can take help from various statistical tool, and for future prediction may be you can also simulate water resources.

I think one can look at the water foot print for food grain production. How efficiently we can reduce the foot print may be attempted starting from land preparation to packaging. By lot of scientific intervention we can reduce the quantity of water used and which will ultimately help in sustaining the food security

Infrastructure of water resources supports food security. Dam construction, development and management of irrigation networks is needed so that the level of service is maintained. Spatial change, land conversion and land degradation, surface water and groundwater competition, surface runoff will affect water resources. The quantity of water in the watershed influenced by the water allocation process which involves the operation of a large number of irrigation infrastructure buildings. Without the effort to control the usage or control of supply, the quantity of water in the watershed will be in critical condition, because theoretically the water requirement has exceeded the availability of water from the existing sources. Water footprint is the large water usage that is divided into commodity products that will give an idea of how much water volume is consumed to produce a mass of agricultural products specifically. Utilization of water appropriately and efficiently to meet water needs in the watershed through the application of intensive rice cultivation methods and efficient or System of Rice Intesification (SRI) that is developing rice management practices that take account of plant growth conditions which is better, especially in the root zone, compared with the technique Traditional way cultivation can provide more crop yields high compared to traditional ways that require a lot of water. Consolidation of water reserves in reservoirs located in the upper reaches facing the dry season through weather modification technology activities (TMC) in order for rain to fall in the reservoir catchment area to increase the inflow rate so that the storage volume increases. Provision of additional surface water with the construction of reservoirs and upstream embankment holds water in the rainy season to be able to utilize the downstream in the dry season. Consolidation of efforts to conserve land to ensure availability water in a changing climate

you can study water management to reduce water consumption in your region

Perhaps the following link from the USGS will shed light on the topic or help on the research; in case you are not aware of it.

You can study the crop water requirement and calculate the water sharing for agricultural sector and how to reduce this share to save water and recommending planting crops with low water requirement and drought tolerant crops.

Dear Kumar,

Regarding your question, we must not forget that any reduction in irrigation water is automatically accompanied by the reduction of the nutrient elements (N, P, K) so, So you have to take into account this parameter for crop growth parameters studied in your area.

Here are three articles that you can read in my profile corresponding to the reduction of water and its impact on the growth parameters of peach culture and the demographical parameters of aphids.

- Impact of water and nitrogen depletion on the Peach orchard infestation

by green peach aphid (Myzus persicae) and its relation with the useful fauna.

- The impact of water and nitrogen depletion on Aphis pomi infestation in the Apple orchard and its relation with the useful fauna and ants.

- Study of the Impact of Water and Nitrogen Resources on Aphid Infestations and Growth and Production Parameters in the Orchard of Peach.
