Abstract. Coping with water scarcity and growing competition for water among different sectors requires proper water management strategies and decision processes. A pre-requisite is a clear understanding of the basin hydrological processes, manageable and unmanageable water flows, the interaction with land use and opportunities to mitigate the negative effects and increase the benefits of water depletion on society. Currently, water professionals do not have a common framework that links depletion to user groups of water and their benefits. The absence of a standard hydrological and water management summary is causing confusion and wrong decisions. The non-availability of water flow data is one of the underpinning reasons for not having operational water accounting systems for river basins in place. In this paper, we introduce Water Accounting Plus (WA+), which is a new framework designed to provide explicit spatial information on water depletion and net withdrawal processes in complex river basins. The influence of land use and landscape evapotranspiration on the water cycle is described explicitly by defining land use groups with common characteristics. WA+ presents four sheets including (i) a resource base sheet, (ii) an evapotranspiration sheet, (iii) a productivity sheet, and (iv) a withdrawal sheet. Every sheet encompasses a set of indicators that summarise the overall water resources situation. The impact of external (e.g., climate change) and internal influences (e.g., infrastructure building) can be estimated by studying the changes in these WA+ indicators. Satellite measurements can be used to acquire a vast amount of required data but is not a precondition for implementing WA+ framework. Data from hydrological models and water allocation models can also be used as inputs to WA+.

In this paper we introduce Water Accounting Plus (WA+), which is a new framework designed to provide explicit spatial information on water depletion and net withdrawal processes in complex river basins. The influence of land use on the water cycle is described explicitly by defining land use groups with common characteristics. Analogous to financial accounting, WA+ presents four sheets including (i) a resource base sheet, (ii) a consumption sheet, (iii) a productivity sheet, and (iv) a withdrawal sheet. Every sheet encompasses a set of indicators that summarize the overall water resources situation. The impact of external (e.g. climate change) and internal influences (e.g. infrastructure building) can be estimated by studying the changes in these WA+ indicators. Satellite measurements can be used for 3 out of the 4 sheets, but is not a precondition for implementing WA+ framework. Data from hydrological models and water allocation models can also be used as inputs to WA+.

Terraced Slopes

This paper presents a quantitative multi-temporal analysis performed in a GIS environment and based on different spatial information sources. The research is aimed at investigating the land use transformations that occurred in a small coastal terraced basin of Eastern Liguria from the early 1950s to 2011. The degree of abandonment of cultivated terraced slopes together with its influence on the distribution, abundance, and magnitude of rainfall-induced shallow landslides were accurately analysed. The analysis showed that a large portion of terraced area (77.4%) has been abandoned over approximately sixty years. This land use transformation has played a crucial role in influencing the hydro-geomorphological processes triggered by a very intense rainstorm that occurred in 2011. The outcomes of the analysis revealed that terraces abandoned for a short time showed the highest landslide susceptibility and that slope failures affecting cultivated zones were characterized by a lower magnitude than those which occurred on abandoned terraced slopes. Furthermore, this study highlights the usefulness of cadastral data in understanding the impact of rainfall-induced landslides due to both a high spatial and thematic accuracy. The obtained results represent a solid basis for the investigation of erosion and the shallow landslide susceptibility of terraced slopes by means of a simulation of land use change scenarios.

The Impact

Bangladesh is a developing and densely populated country. The process of urbanization is increasing day by day in this country. But planned development is challenging here. Bangladesh is the largest delta in the world. Due to geographical location, Bangladesh is naturally prone to disasters. Not only that Bangladesh is also under the thread of global worming and climate change related issues. Although Bangladesh is not contributing much to global greenhouse gas increase, Bangladesh is one of the largest victims of the adverse impacts of global worming and climate change. To reduce the impact and damage it is necessary to formulate risk reduction land use plan incorporating socioeconomic and geo-physical aspects. Mirsharai is a coastal Upazila situated in Chattogram District of Bangladesh. The area is highly prone to disaster and affected by climate change related problems. So, the area is ideal for this kind of study. In this paper, socioeconomic characteristics such as affordability, investment potentiality, demand and need has been analyzed. Result shows that people’s affordability is not good in most of the places of Mirsharai Upazila but in some isolated areas like small urban area or growth centres, people’s affordability and other socioeconomic conditions are good. Geo-physical aspects such as Infrastructure, ground water recharge, water logging tendency, Road accessibility, Ground elevation, Agricultural crop pattern and Land use were used to calculate development suitability and development conflict using Multi-criteria Analysis technique. Based on development suitability and conflict 4 category were identified as highly suitable, suitable, moderately suitable and less suitable area for development. Similarly, highly conflicted, conflicted, moderately conflicted and less conflicted areas for development were identified. Finally, by comparing development conflict and suitability maps, a relative development suitability map was produced marking highly suitable, suitable, moderately suitable, less suitable, partially unsuitable and completely unsuitable areas for development. These types of socioeconomic and geo-physical condition analysis can help making clear understanding on the study area for making risk sensitive land use plan.

The Impact

River basins in Great Britain and Ireland have been characterized by periods of hillslope and valley floor instability during the Holocene, reflecting sensitivity to both climate change and anthropogenic disturbance. In contrast to climatic controls, which have been relatively well documented, human impacts on and interactions with river basins remain unclear. There is now, however, a growing impetus to elucidate more fully the impact of anthropogenic activity on sediment supply and runoff, given that land-use change is thought to have exacerbated recent flooding in the UK (eg, the ‘Millennium'floods of 2000). The aim of this paper is to critically review the significance of Holocene land use on hillslope and valley floor stability in Great Britain and Ireland. The most widely reported impacts of land-use change on geomorphic activity include hillslope erosion and gully development, valley floor alluviation, river channel incision and elevated water tables. In the majority of cases, however, causal relationships are difficult to establish, due primarily to inadequate dating control. Even where geomorphic instability can be linked to land-use change, it is apparent that eroded material is often stored as colluvium, which together with evidence of diachronus hillslope and valley floor instability, raises important questions and identifies uncertainties regarding the dynamics and extent of sediment transfer within river basins. Such uncertainty has important implications for understanding how river basins will behave in response to future environmental change.

Abstract. The paper describes the application of a new Water Accounting Plus (WA+) framework to produce spatial information on water flows, sinks, uses, storages and assets, in the Indus Basin, South Asia. It demonstrates how satellite-derived estimates of land use, land cover, rainfall, evaporation (E), transpiration (T), interception (I) and biomass production can be used in the context of WA+. The results for one selected year showed that total annual water depletion in the basin (502 km3) plus outflows (21 km3) exceeded total precipitation (482 km3). The deficit in supply was augmented through abstractions beyond actual capacity, mainly from groundwater storage (30 km3). The "landscape ET" (depletion directly from rainfall) was 344 km3 (69% of total consumption). "Blue water" depletion ("utilized flow") was 158 km3 (31%). Agriculture was the biggest water consumer and accounted for 59% of the total depletion (297 km3), of which 85% (254 km3) was through irrigated agriculture and the remaining 15% (44 km3) through rainfed systems. While the estimated basin irrigation efficiency was 0.84, due to excessive evaporative losses in agricultural areas, half of all water consumption in the basin was non-beneficial. Average rainfed crop yields were 0.9 t ha−1 and 7.8 t ha−1 for two irrigated crop growing seasons combined. Water productivity was low due to a lack of proper agronomical practices and poor farm water management. The paper concludes that the opportunity for a food-secured and sustainable future for the Indus Basin lies in focusing on reducing soil evaporation. Results of future scenario analyses suggest that by implementing techniques to convert soil evaporation to crop transpiration will not only increase production but can also result in significant water savings that would ease the pressure on the fast declining storage.

Abstract Distributed rainfall-runoff model simulations are often used to evaluate the impact of changes on the generation of runoff. These models have the advantage of reflecting the effects of land use on spatially distributed model parameters. The article deals with changes in forest associations as a result of global climate changes. In this article the WetSpa model was used for estimating the impact of forest changes on the runoff regime in the Hron and Topla river basins, with an emphasis on the parameterization of the land cover properties in the runoff simulations. The parameters of the model were estimated using climate data and three digital map layers: a land-use map, soil map and digital elevation model. This work contains two land use change scenarios of forest associations and also two scenarios of global climate change. Both types of scenarios of changes were prepared, and the runoff under the new conditions was simulated.

The Alps function as a water tower for four of the major European river basins. However, a climate change-induced shift in mountain hydrological regimes and the future predicted disappearance of Alpine glaciers at the end of this century will have consequences for water management in both the Alps and the water-dependent lowlands. In this paper the importance of mountain water in the European lowlands and the impact of climate change on the water sector in both the mountains and lowlands are shown. Different demand stakeholders of the Alpine water sector will be affected. Dependent on the particular region in the Alps, problems will be less or more severe but generally adaptation can be achieved by means of the right investments and policies. However, major impacts on the water sector in the lowlands of the Danube, Rhine, Rhone and Po river basins are foreseen. Integrated water management at basin level is required to cope with these challenges.

The Relationship

The article considers changes in the legislation on the circulation of agricultural land, which are aimed at stimulating the development of property institutions and land leases, as well as modern trends in the organizational and legal relations between owners and tenants of agricultural land. The contribution of the resource potential of agricultural production cooperatives to the development of the resource base of agriculture has been assessed using the example of the Udmurt Republic. Factors of organizational and legal order have been identified, which affect the level of development of internal production cooperation. The impact of organizational and legal factors concerning the registration of land plots on the effectiveness of agricultural production cooperatives has been analyzed and assessed. The factor that characterizes the relationship between the level of legal registration of land and the efficiency of land use is justified. It is recommended to apply this factor to adjust various estimates of land turnover. There is a weak relationship between the organizational and legal forms of land management and the profitability and current liquidity of cooperatives in relation to the municipal districts of the Udmurt Republic. Conclusions are drawn on the state and trends of development of intra-industrial cooperation.

Climate and other human-induced changes will increase water scarcity in world areas such as in the Mediterranean. Adaptation principles need to be urgently incorporated into water management and stakeholder engagement needs to be strengthened at all steps of the management cycle. This study aimed to analyse and compare stakeholder-preferred water management options (WMOs) to face climate change related challenges and to foster adaptation in four Mediterranean river basins. The challenges and WMOs of the four river basins identified by stakeholders were analysed examining to what extent the WMOs tackled the identified challenges. The impact of the WMOs resulting from a participatory modelling method was included in a comparative analysis of the stakeholders’ WMOs preferences. The results indicate the participatory approach that was applied allowed local priorities and real-world challenges to be defined with adequate detail as well as the definition of tailored responses. The participatory impact analysis provided an integrated view of the river basin as an interrelated system. The participatory evaluation of the WMOs was able to consider a wide range of elements and was able reflect the combined preferences of the stakeholders. Moreover, it allowed groups of basin actors with highly diverse profiles and concerns to further promote sets of these WMOs as input into decision making processes.
