Blockwise assessment of crop evapotranspiration in central Punjab, India

Punjab, the major riparian State, has a limited share in its three perennial rivers (Sutlej, Ravi and Beas). A systematic planning of groundwater exploitation using modern technologies needs to be adopted for the proper utilization and management of groundwater resource. The present study was aimed to estimate the blockwise crop evapotranspiration (ETc) during kharif and rabi season in Central Punjab and to develop a GIS based maps of crop evapotranspiration. The results revealed that the blocks namely Makhu and Zira of Ferozepur district had the maximum (747 mm) crop water demand whereas block Fatehgarh Churian of Gurdaspur district had the least (445 mm) crop water demand. The outcome of the study revealed that crop water demand varies from 450 mm to 750 mm in kharif and rabi season in Central Punjab. The ETc maps derived in the study were useful in determining areas with highest water demands.

Establishment of Dams and Embankments of Frontier River of North East Part of India: Impact on North-Western Region of Bangladesh

India has built barrages on 17 more rivers in the east and northeast border with Bangladesh. Most of these dams and embankments act as the main barrier to flow water towards downstream like Bangladesh. As a result the rivers of Bangladesh that comes from India are falling in crisis of proper water. A study showed about 30 rivers of north-western part of Bangladesh gets very few water only due to dams and embankment made by India at the upstream of those rivers. Such massive water control projects of India are clearly a threat for a state that lies down of those. Unfortunately, and often ironically, national leaders of our country prefer to negotiate this sensitive matter rather than to make a strong protect of this inhuman and unethical activities. What is more astonishing news is that some time our state policy makers like to keep silent and avoid about it. India is always ready to controlling nature to serve economic development rather than addressing issues of trans-boundary and socio-environmental responsibilities. In fact, Indian plan to divert the water of Frontier Rivers is increasing at an alarming rate for Bangladesh. Here one thing is mentionable that is this types of project even harmful for India also. And peoples of north western state of India are in against of such harmful and high ambitious unnecessary project. Some time they also make a protest against it. Recently China and India are going to establish a large dam at the up Stream of Brahmaputra River. It would impair India’s own plan to link approximately thirty of its own rivers, a project that is bound to affect the downstream riparian state of Bangladesh. As a result drastic fall in the water flow of Teesta during the lean season, especially in February and March will occur in more frequent and will seriously hampers irrigation in Bangladesh. Such international trans-boundary river development projects raise many important issues. They never consider the impact that will impose upon the down stream part like Bangladesh.

Development of Water Pollution Control in Austria–An Example of a Riparian State in the Drainage Area of the River Danube

In 1988, some 70% of the Austrian population had sewerage and some percentage-points less biological wastewater treatment. Industry - except pulp and paper - had in 1988 biological treatment for 80% of its load, and pulp and paper for 20% of its load. The paper deals with the development of Austrian Water Law, with water pollution control and its advancement in the period 1968 to 1988, with foreseeable problem areas in water pollution control in the coming years, and finally presents a table with data relating to the main riparian states in the River Danube Basin. From these data and the development in Austria over time, it is to be concluded that the actual application of activities in water pollution control seem to be determined primarily by public or political awareness of this specific task and not so much by resources available.

Planning Criteria for Large-Scale Fisheries Development with Special Reference to the Indian Ocean

Criteria for large-scale fishery development are determined by motives of the developer, which are primarily economic. Economically viable fishery developments invariably have positive social side effects, whereas socially oriented developments seldom have positive economic results.Primary criteria for development are: species of fish available; the location, size and behavior of the stocks; and ultimately, the unit annual average catch rate of the "best boat." Primary criteria also include hospitality of the riparian state, as measured by its policies and their implementation, the intensity of economic nationalism, and political stability; and the nature of the people, their industriousness, and the ability of the society to absorb capital. The last is a major consideration.Secondary criteria include such physical considerations as crew amenities, vessel support facilities, communications, and transport.Tertiary criteria include the overall size of the project, the dimensions of the market, the nature of competition, the possibility of overcapitalization, and, ultimately, luck and the behavior of humans and fishes.
