Dam effect on groundwater characteristics from area under semi-arid climate: case of the Zerrar dam within Essaouira basin (Morocco)

Mohammed Bahir, Driss Ouazar, Salah Ouhamdouch

Carbonates and Evaporites > 2019 > 34 > 3 > 709-720

Morocco has 140 large dams with a total capacity of 17 Gm³. The amount of potential fresh water is decreased by sedimentation of clays and/or soil in the dam’s reservoirs. It is estimated at 70 million m³, surface evaporation and water loss by the banks and foundations. In this study, the environmental stable and radioactive isotopes together with geochemical and piezometric data were used to assess...

Drought and water mobilization in semi-arid zone: The example of Hammam Boughrara dam (North-West of Algeria)

H. Adjim, A. Djedid

Journal of Water and Land Development > 2018 > no. 37 > 3--10

The dam of Hammam Boughrara is an embankment dam built in a transboundary basin, between Algeria and Morocco; it was type-approved and delivered in 1998. This dam was supposed to solve the lack of drinking water in Oran (Algeria's second largest city) and enhance the agricultural perimeter of the area. It should regulate an annual water volume of 59 million m³. However, the northwest Algeria has experienced...

Variation in growth, wood density and carbon concentration in five tree and shrub species in Niger

John C. Weber, Carmen Sotelo Montes, Tougiani Abasse, Carlos R. Sanquetta, more

New Forests > 2018 > 49 > 1 > 35-51

There is little information about variation in growth, wood density and carbon concentration in native tree and shrub species in Africa. This information is needed to make realistic projections about carbon sequestration of different species in different environments. Farmers manage natural regeneration of many native species in the drylands of Niger, so there is interest in carbon sequestration potential...

Structural diversity closely associated with canopy species diversity and stand age in species-poor montane forests on Loess Plateau of China

N. Liu, H. Wang, H. Nan

Polish Journal of Ecology > 2017 > 65 > 2

High species diversity is often accompanied with and supported by a diversified stand structure in species-rich natural forests. However, the relationship between species diversity and stand structural diversity is less examined in species-poor forests. In montane forests on Loess Plateau of north-central China in a semi-arid climate zone, canopy species diversity and vertical structure of 57 broadleaves,...

Uses and vulnerability of ligneous species exploited by local population of northern Burkina Faso in their adaptation strategies to changing environments

Pauline Ouédraogo, Babou André Bationo, Josias Sanou, Salifou Traoré, more

Agriculture & Food Security > 2017 > 6 > 1 > 1-16

Background Arid and semi-arid areas of West Africa are highly subject to climate change effects. This is combined to other drivers such as population growth and livestock number increase. To cope with such changing environment, endogenous adaptation strategies of poor local communities rely on the use of natural resources through empirical knowledge. Unfortunately, these knowledge and practices are...

Quality of urban runoff in wet and dry seasons: a case study in a semi-arid zone

Joyce Ortiz-Hernández, Carlos Lucho-Constantino, Liliana Lizárraga-Mendiola, Rosa Icela Beltrán-Hernández, more

Environmental Science and Pollution Research > 2016 > 23 > 24 > 25156- 25168

Urban runoff (UR) is a promising new resource that may alleviate growing tensions in numerous arid and semi-arid regions of the world. However, it is precisely in these zones that the available UR quality characteristics are scarcer. This work aims to evaluate a wide set of parameters to establish a detailed approach to both the quality of UR in a midsized city in Central Mexico and the feasibility...

Estimation of Time Variant Water Availability and Irrigation Potential of Small Ponds in a Semi-arid Region of Rajasthan, India

Shakir Ali

Journal of The Institution of Engineers (India): Series A > 2016 > 97 > 1 > 43-51

A field experiment was conducted to assess water availability and irrigation potential of two small, shallow and Ephemeral ponds located in a small watershed of the semi-arid region of Rajasthan, India. The Holistic Water Depth Simulation (HWDS) model was employed for estimating the pond water availability with 3 years field data (2006–2008). The analysis revealed that the value of depth of water...

The critical role of ants in the extensive dispersal of Acacia seeds revealed by genetic parentage assignment

Caitlin M. Pascov, Paul G. Nevill, Carole P. Elliott, Jonathan D. Majer, more

Oecologia > 2015 > 179 > 4 > 1123-1134

Ants are prominent seed dispersal agents in many ecosystems, and dispersal distances are small in comparison with vertebrate dispersal agents. However, the distance and distribution of ant-mediated dispersal in arid/semi-arid environments remains poorly explored. We used microsatellite markers and parentage assignment to quantify the distance and distribution of dispersed seeds of Acacia karina, retrieved...

S.L. Falasca, C. Miranda del Fresno, A. Ulberich

International Journal of Hydrogen Energy > 2012 > 37 > 19 > 14843- 14848

Syagrus romanzoffiana is a palm native to Argentina, where it is known by the name ‘Pindó’.This palm extends from the Misionera Forest through the gallery Forest, being the Parana Delta area the southern limit of dispersion. In this area, the large volumes of water from the rivers create a moderating effect, reducing the daily temperature range and the days of frosts.The aim of this study was to delimit...

Changes in water relations for Acacia ancistrocarpa on natural and mine-rehabilitation sites in response to an experimental wetting pulse in the Great Sandy Desert

Alasdair M. Grigg, Hans Lambers, Erik J. Veneklaas

Plant and Soil > 2010 > 326 > 1-2 > 75-96

Vegetation plays an essential role in mine-site rehabilitation as it serves to reduce erosion and extract moisture from the soil cover, thus minimising deep drainage to potentially hazardous materials below. Plant water-use patterns and root development are likely to be impacted where subsoils are physically and/or chemically inhospitable and close to the surface, particularly in arid and semi-arid...
