The utilization of groundwater for irrigation purposes in Indonesia, known as Jaringan Irigasi Air Tanah (JIAT), has been developed since 1970 and nowadays they can be found in nearly all region in Indonesia. For example, in Lampung Province, there are 112 JIAT facilities under the authority of the Mesuji Sekampung River Basin Agency. One of the benefits of JIAT is its reliability as it warrants water availability all year long. On the other hand, JIAT operation is costly. Therefore, agricultural irrigation system such as JIAT is less attractive to most farmers unless there is some kind of government subsidy. This paper presents an economic study of JIAT by comparing the benefit for the farmers with the operation cost to determine the feasibility of a JIAT facility. This study is based on the inventory data of JIAT facilities in Lampung Province. The method used in this study is descriptive quantitative. The final result of this study is a recommendation for feasibility requirements for a JIAT facility as a whole, which can be used by River Basin Agencies (BWS/BBWS) in Indonesia as a guideline to determine the feasibility and sustainability of a JIAT facility.

The paper deals with the syntaxonomy of vegetation on the sandy outcrops in the Pechora (Malozemelskaya and Bolshezemelskaya) tundra. The vegetation was classified using the Brown-Blanke approach. Communities were referred to 3 associations: Arctostaphylo alpini—Empetretum hermaphroditi (Zinserling 1935) Koroleva 1994, Elymo—Festucetum arenariae (Regel 1923) Nordhagen 1955 and Rumici graminifoliae—Festucetum sabulosae ass. nov. Five new variants were suggested within the first association and 2 subassociations and 4 variants within the last one. Syntaxon description and phytocoenological tables are presented. The vegetation on each sandy outcrops represents a complex of communities fragmentary located on the scars area. Subass. inops of ass. Rumici graminifoliae—Festucetum sabulosae is more common in the Ortina river basin and occurs at the bottom of blowing hollows. Syntaxa of ass. Elymo—Festucetum arenariae and var. Festuca rubra of ass. Rumici graminifoliae—Festucetum sabulosae are situated at the mobile sands in the central part, while var. Arctous alpina of ass. Rumici graminifoliae—Festucetum sabulosae occurs on a periphery of out­crops where substratum is stable. The variants inops and typicum of ass. Arctostaphylo alpini—Empetretum hermaphroditi occuring in the Sedujyakha river basin occur mostly in the centre of sandy outcrops, and the other ones can be met on their periphery. Ecological conditions determine poor diversity of syntaxa of the association level. Geographical position (the Sedujyakha river basin belongs to the northern hypoarctic tundras, the Ortina river basin — to the southern hypoarctic ones), geomorphology (in the first site — tops of hills and ridges, in the second one — watershed areas) and area of sandy outcrops (200—3000 m2 for the first and 61000—418000 m2 for the second site respectively) are the reasons for the less diverse communities found in each study site. A great number of variants is conditioned by succession stages of vegetation and instability of the substrates.

Water Scarce

More than one-quarter of the world’s population lives in water-scarce areas, while most countries share at least one transboundary river. If water scarcity is this prevalent, should we expect riparian countries to fight over the water allocation of shared rivers? To answer this question, I develop a modified one-shot three-stage river-sharing game where countries can resort to force to solve their water allocation problem. Using backward induction, I solve for the probability of the downstream country initiating conflict against the upstream country and the likelihood of the latter responding with force to the former’s hostile actions. I test the model empirically using a set of all upstream–downstream riparian dyads with available data from AQUASTAT and the Correlates of War Project for the years 1960–2010. The main contribution of this paper is that it demonstrates how upstream and downstream riparian countries differ in their decision to use force against the other country when experiencing water scarcity. I find that water scarcity increases the likelihood of the downstream country initiating the conflict, but it has no effect on the upstream country’s likelihood of responding with force. If history is a predictor of the future, then the results imply that as more riparian countries become water-scarce, militarized conflicts between upstream and downstream countries are likely to increase, especially if there is heterogeneity in water availability between the riparian dyad.

Minor Irrigation

The study examined the impact of minor irrigation on agricultural production and evaluated the gap between IPC and IPU in the Keonjhar district of Odisha. For this rationale, data were collected from 210 farm households through the primary survey. In support of the analysis, the Cobb Douglas model and factor analysis were used. The results revealed that the input use efficiency had a positive and significant impact on paddy production the most in all the MIPs regions compared to the other crops. However, the study indicated that insufficient water availability was the major cause behind the gap between irrigation potential created and utilised. Thus, minor irrigation played a crucial role in enhancing agricultural production in hilly regions. With the enthusiastic participation of planners, effective working of Pani Panchayats, canals, and upstream control, NGOs' involvement can achieve selfsufficiency in agricultural production by encouraging minor irrigation projects in the hilly province.

This paper deals with the relation between statistical analysis as applied in economic inquiry and history as written or interpreted by economic historians. Although both these branches of economic study derive from the same body of raw materials of inquiry—the recordable past and present of economic society—each has developed in comparative isolation from the other. Statistical economists have failed to utilize adequately the contributions that economic historians have made to our knowledge of the past; and historians have rarely employed either the analytical tools or the basic theoretical hypotheses of statistical research. It is the thesis of this essay that such failure to effect a close interrelation between historical approach and statistical analysis needs to be corrected in the light of the final goal of economic study.

Abstract. It is a matter of current study to determine potential climate changes in different parts of the world, especially in regions like a basin which has the potential to affect socioeconomic and environmental issues in a defined area. This study provides a comparison between several climate change indices trends of two very different basins in Mexico, one located in the northern arid region (the Conchos River basin) and the other in the southern humid area (the Usumacinta River basin). First, quality control, homogenization, and completion of the missing data were applied before calculating the climate change indices and their respective trends for the combined period 1961–1994. A clear warming signal was found for the two basins in addition to an increment in the DTR, in agreement with other studies in Mexico. Also, the Conchos River basin was found to be more humid and the Usumacinta River basin drier, in accordance to a supposed seesaw behavior indicated in previous analysis.

AbstractChanges in runoff trends have caused severe water shortages and ecological problems in agriculture and human well-being in Nigeria. Understanding the long-term (inter-annual to decadal) variations of water availability in river basins is paramount for water resources management and climate change adaptation. Climate change in Northern Nigeria could lead to change of the hydrological cycle and water availability. Moreover, the linkage between climatic changes and streamflow fluctuations is poorly documented in this area. Therefore, this study examined temporal trends in rainfall, temperature and runoff records of Kaduna River basin. Using appropriate statistical tools and participatory survey, trends in streamflow and their linkages with the climate indices were explored to determine their amplifying impacts on water availability and impacts on livelihoods downstream the basin. Analysis indicate variable rainfall trend with significant wet and dry periods. Unlike rainfall, temperature showed annual and seasonal scale statistically increasing trend. Runoff exhibit increasing tendency but only statistically significant on annual scale as investigated with Mann–Kendall trend test. Sen’s estimator values stood in agreement with Mann–Kendall test for all variables. Kendall tau and partial correlation results revealed the influence of climatic variables on runoff. Based on the survey, some of the hydrological implications and current water stress conditions of these fluctuations for the downstream inhabitants were itemized. With increasing risk of climate change and demand for water, we therefore recommend developing adaptive measures in seasonal regime of water availability and future work on modelling of the diverse hydrological characteristics of the entire basin.
