Ground water origin and movement in the upper Yarmouk Basin,Northern Jordan

The Upper Yarmouk basin in northern Jordan has become an increasingly important groundwater resource in recent years. Despite this, studies of groundwater recharge and movement in the area are limited, and mostly parts of larger scale regional data syntheses. Detailed analysis of the hydrogeology, hydrochemistry and isotopic data indicate a more complex system than previously presented. Whereas earlier studies suggested that groundwater is derived from a single aquifer, this study suggests abstraction from multiple aquifers. Moreover, faults and lineaments in the area may be causing segmentation and limited flow within individual aquifers. The isotopic and hydrochemical data suggest that local recharge plays a significant role in the hydrogeologic situation in the study area. This appears to be mostly happening in the hilly zone in the central part of the study area.     

河西走廊疏勒河流域水资源管理问题分析

从水资源管理体制、配置程序、市场化管理等方面探讨了河西走廊疏勒河流域水资源管理及存在的问题。目前流域已建成较健全的用水者协会体系,水价和水权在不断调整以适应水资源管理的需求。其管理存在以下问题：受地方行政、企业等多方权力博弈的影响,地表水和地下水处于双线管理状态,未能实现流域水资源的全面统一管理;用水者协会的职能未得到充分发挥,公众参与水资源管理不积极;流域内水价、水权制度不完善。建议如下：应在甘肃省水利厅和酒泉市政府之间形成协调机制,以协调各相关方的权益,完善流域管理局和地方政府统一协调的水资源管理体系,实现流域水资源的集成管理;加强流域机构立法,实现流域水资源的统一管理与调配;将协会的职责和义务融入到村委会的职务中,并完善水价制度,建立水权交易市场,以调动公众的自我管理和实现水资源的高效利用。

Integrative assessment of hydrological, ecological, and economic systems for water resources management at river basin scale

This study presents a basin-scale integrative hydrological, ecological, and economic (HEE) modeling system, aimed at evaluating the impact of resources management, especially agricultural water resources management, on the sustainability of regional water resources. The hydrological model in the modeling system was adapted from SWAT, the Soil and Water Assessment Tool, to simulate the water balance in terms of soil moisture, evapotranspiration, and streamflow. An ecological model was integrated into the hydrological model to compute the ecosystem production of biomass production and yield for different land use types. The economic model estimated the monetary values of crop production and water productivity over irrigated areas. The modeling system was primarily integrated and run on a Windows platform and was able to produce simulation results at daily time steps with a spatial resolution of hydrological response unit (HRU). The modeling system was then calibrated over the period from 1983 to 1991 for the upper and middle parts of the Yellow River basin, China. Calibration results showed that the efficiencies of the modeling system in simulating monthly streamflow over 5 hydrological stations were from 0.54 to 0.68 with an average of 0.64, indicating an acceptable calibration. Preliminary simulation results from 1986 to 1995 revealed that water use in the study region has largely reduced the streamflow in many parts of the area except for that in the riverhead. Spatial distribution of biomass production, and crop yield showed a strong impact of irrigation on agricultural production. Water productivity over irrigated cropland ranged from 1 to 1640 USD/(ha·mm⁻¹), indicating a wide variation of the production conditions within the study region and a great potential in promoting water use efficiency in low water productivity areas. Generally, simulation results from this study indicated that the modeling system was capable of tracking the temporal and spatial variability of pertinent water balance variables, ecosystem dynamics, and regional economy, and provided a useful simulation tool in evaluating long-term water resources management strategies in a basin scale.

Collective irrigation reloaded. Re-collection and re-moralization of water management after privatization in Spain

In recent decades, water has been subjected to different commodification and de-collectivization processes. Increasingly, this is also affecting collective irrigation water management. Critical analysis of this privatization and de-collectivization wave in the irrigation sector has mainly focused on neoliberal institutional policies and market-oriented legislation. However, subtly and silently but equally determinant, the adoption of water-saving technologies is fostering the penetration of private enterprise and market-based governance into these hydro-social settings. This paper discusses this phenomenon through a case study of the community of Senyera in Valencia, Spain, tracking the privatization and subsequent contestation and re-takeover of water management by irrigation system users. The article shows how privatization removes users’ autonomy in the name of common well-being, and increases irrigation costs in a context of little transparency. But the case also highlights users’ capacity to re-value and re-signify their past collective action, remembering and ‘re-membering to’ the collective. Senyera water users critically and reflexively analyse privatization, reconstruct societal relationships around and embedded inside the new technology, and re-collectivize and re-moralize irrigation management in a new hydro-social scenario.

Actors, options and the challenges of forest management in anglophone Cameroon

Natural resources, especially the forest provide a means of livelihood to rural communities in most developing countries. Unfortunately these resources are under the threat of disappearing because of high population growth rates and poverty that characterise these communities. Any attempt by development agencies at conserving these resources is tantamount to depriving these rural areas of their survival base. Yet due to its strategic socio-economic and cultural importance, the forest ecosystem needs to be sustained for future generations. This paper examines the various challenges faced by the State and other conservation agencies in natural resource management and the possible options which can be employed in an effort to ensure a sustainable exploitation of the forest in Anglophone Cameroon. It discusses the efforts of these actors, within the framework of the emerging concept of community forestry, local community strengthening and integrated rural development. While highlighting some of the achievements of international NGOs like Bird Life International and World Wide Fund for Nature in the region, the study concludes that the future of sustainable management of forest resources relies on a holistic poverty alleviation approach that takes into consideration the empowerment of these communities. This will ensure that they participate and benefit from the exploitation of the resources in the form of local development.

苏州城市规划区Ⅱ承压水开采与地面沉降预防控制研究

在孔隙承压水开采与地面沉降的关系上存在2种观点。水、土应力平衡理论认为：只要开采承压水，就会引发应力失衡并导致地面沉降；而水、土动态平衡理论则认为：除非开采水压力至水、土应力平衡面以下，否则不会引发地面沉降。苏州城市规划区第Ⅱ承压水开采水位与地面沉降动态观测表明，在-33m处存在一个天然动态水、土应力平衡面。第Ⅱ承压含水层形成后，经上覆堆积物自重压力长期压缩作用，其水压力具较高的压强．这种天然状态下产生的弹性释放储存量可开采利用多少，取决于开采状态下水、土应力平衡时可消耗压力水柱高度中的水头值。因而地面沉降的根本原因是开采水位超过了-33m，突破了天然状态水、土应力平衡面水位。Ⅱ承压含水层在天然状态受上覆堆积物重力产生的高压强弹性释放储存量现象，可以帮助我们确立该地区孔隙Ⅱ承压水开采不产生地面沉降的临界水位(水、土应力平衡面)。这一点对承压水开采条件、可开采资源性质具有重大实际意义。同样可以应用于饱受地面沉降困扰的无锡、常州及周边地区，为地下水开发利用政策由单一的封井停采转为目标水位控制开采提供了科学依据。同时也为此政策在承压水动力学机制上找到了内在原因。
