Rajasthan is the largest state of India in terms of area and it covers about 10.4% of the total area of India but only 1.04% of the water resources, hence there is lack of water resources for 70% of the state's agricultural economy. The uncertainty of the monsoon creates problems of employment and irregularity along with hindering the development of agriculture. Such problems have revealed an important requirement of irrigation in the state. The paper will explain about the main sources, needs and importance of irrigation in Rajasthan. The study also focuses on the area irrigated by irrigation resources in Rajasthan. Main irrigation projects of Rajasthan like interstate multipurpose river valley projects of Rajasthan, major irrigation projects of Rajasthan, medium projects of Rajasthan, minor irrigation projects of Rajasthan are explained properly with facts and figures in the study. The paper also highlights the development of irrigation during plans and its progress in gross irrigated area in Rajasthan. Allocation of expenses of public sector irrigation and flood control under the five-year plans in Rajasthan were part of the study. In the last paper ended explaining about the barriers to irrigation development, suggestions and conclusion. Financial difficulty, rising cost of irrigation projects, problem of full utilization of irrigation potential, reservoir problems, inter-State disputes, problem of environmental protection, corruption, red tape and political partisanship, unnecessary delay are the various problems faced by the farmers. To overcome these problem suggestions given like government should focus on mobilizing more resources, seek foreign cooperation, control over corruption, careful use of water and proper drainage system, disputes should be settled quickly and without political pressure, timely completion of projects, etc.

Set Up

The northbound migration of maining activities in the Emscher Region is making the open combined sewer system obsolete. This complex task requires a large number of water resources development activities in the subcatchments of tributaries. To harmonize these single activities and to evaluate their performance as part of the complete system a detailed rainfall-runoff-model of the whole Emscher system has been set up. Intensive anthropogenic impacts made it necessary to use actual system data to run advanced modeling techniques. The model set-up and first applications have been recently completed. The reconstruction of the extreme storm event of January 1995 showed excellent results. One of the major objectives is the reduction of flood levels by decentral retention measures. An evaluation matrix will be set up for the 22 potential sites for flood storage with a total volume of 4.8 million m3. Reconstruction plans developed through interdisciplinary investigations will be ranked concerning potential for realization and water resources benefits. In the mean and long range the applicability of approaches for flood control strategies using real-time forecasting models will be checked.

Abstract Recently urban waterlogging problems have become more and more serious, and the construction of an airport runway makes the impervious area of the airport high, which leads to the deterioration of the water environment and frequent waterlogging disasters. It is of great significance to design and construct the sponge airport with low impact development (LID) facilities. In this paper, we take catchment N1 of Beijing Daxing International Airport as a case study. The LID facilities are designed and the runoff process of a heavy rainfall in catchment N1 is simulated before and after the implementation of LID facilities. The results show that the total amount of surface runoff, the number of overflow junctions and full-flow conduits of the rainwater drainage system in catchment N1 of Beijing Daxing International Airport are significantly reduced after the implementation of the LID facilities. Therefore, the application of LID facilities has greatly improved the ability of the airport to remove rainwater and effectively alleviated the risk of waterlogging in the airport flight area. This study provides theoretical support for airport designers and managers to solve flood control and rainwater drainage problems and has vital practical significance.

Campo de Dalías, located in southeastern Spain, is the greatest European exponent of greenhouse agriculture. The development of this type of agriculture has led to an exponential economic development of one of the poorest areas of Spain, in a short period of time. Simultaneously, it has brought about a serious alteration of natural resources. This article will study the temporal evolution of changes in land use, and the exploitation of groundwater. Likewise, this study will delve into the technological development in greenhouses (irrigation techniques, new water resources, greenhouse structures or improvement in cultivation techniques) seeking a sustainable intensification of agriculture under plastic. This sustainable intensification also implies the conservation of existing natural areas.

Red Tape, Rule Legitimacy, and Public Service Motivation: Experimental Evidence From Korean Citizens

Output Legitimacy

While legitimacy plays a key role in determining if a public sector rule or process objectively qualifies as red tape, it is unclear if legitimacy shapes subjective red tape judgments. We use a sample of South Korean citizens and a vignette-based survey experiment describing applying for a small business COVID-19 relief fund to test the relevance of rule legitimacy for perceived red tape. We find that obtaining a favorable outcome (receiving the fund) reduces perceived red tape, but that neither input nor output legitimacy plays a consistent role. Second, we find that public service motivation moderates the role of both input and output legitimacy on perceived red tape, though in different directions. For those with high levels of public service motivation, output legitimacy reduces perceived red tape. However, for the same group, input legitimacy increases it. We provide a detailed discussion of the contributions of our study.
