Ramli |The demand for freshwater is on the increase due to the rapid growth in the world's population while the effect of global warming and climate change cause severe threat to water use and food security. Consequently, irrigation systems are tremend[...]Article
A. Elbeltagi ; J. Deng ; K. Wang ; Y. Hong |Modeling crop water use as a useful decision tool for agricultural policy decision-makers to improve water-use efficiency has been increasing. This study aimed to estimate, forecast, and model the green and blue water footprints (WFg and WFb, re[...]Article
Reuse of wastewater (WW) as an agricultural irrigation source is being considered with increasing interest, mainly in arid and semiarid zones. However, due to the complex nature of WW its reuse can have an impact on the fate of the pesticides ad[...]Article
Water has important economic values, mainly in the agricultural sector. Beside enhancing agricultural output and crop diversification, irrigation generates positive externalities which have been little emphasized by the literature. The purpose o[...]Article
The overexploitation of groundwater for irrigation purposes is a general problem affecting the management of common resources. The objective of this study was to analyze some of the policy options when facing this issue. A choice experiment was [...]Article
En France, depuis ladoption de la loi sur leau de 1992, la gouvernance territoriale de leau et des milieux aquatiques sest progressivement structurée - avec de fortes variations géographiques - autour des Schémas daménagement et de gestion [...]Article
Apulia has a considerable demand of irrigation water, however high inefficiency levels of the collective water networks force most of the regional farms to use groundwater, with a consequent worsening of its quality, as well as of soil and crops[...]Article
Understanding the complex relationship between water, agriculture and poverty (WAP) is essential for informed policy-making in light of increasing demand for scarce water resources and greater climatic variability. Yet, our understanding of the [...]Article
The pressure of growing urbanization, industrialization and water scarcity resulting from climate change imposes limitations on the amount of water allocated to agriculture. There will need to be an increase in food production of almost 50% by 2[...]Article
F. Maselli ; M. Chiesi ; L. Angeli ; L. Fibbi ; B. Rapi ; M. Romani ; F. Sabatini |Recent investigations have shown the potential of a water balance method based on Normalized Difference Vegetation Index (NDVI) data to estimate actual evapotranspiration (ETa) of Mediterranean grasslands and croplands. The method uses the Fract[...]Article
This study describes the evolution of the Spanish irrigated sector and focuses on water abstraction, water consumption, and energy use in the period 19502017. The analysis shows evidence of the basins reaching closure state and the impact on en[...]Article
M. Tuninetti ; L. Ridolfi ; F. Laio |International agricultural trade triggers inter-dependency among distant countries, not only in economic terms but also under an environmental perspective. Agricultural trade has been shown to drive environmental threats pertaining to biodiversi[...]Article
Crop water production functions (quantifying crop yield as a function of irrigation rate) can help in the design of management systems that reduce the water footprint. We examined the role of parameter uncertainties in characterizing production [...]Article
N. Dahbi ; L. Messaoudi |Les eaux usées sont de plus en plus utilisées par les agriculteurs des pays en développement. Cette utilisation est motivée principalement par : (a) la pénurie grandissante des ressources en eau et les tensions de plus en plus fortes sur ces res[...]Article
Etant conscient de limportance et de lactualité du sujet de la gestion de leau au Maroc. Et surtout de la gestion rationnelle qui devrait tenir compte des impacts du changement climatique sur les ressources naturelles et sur lagriculture. No[...]Article
I. Ferchichi ; I. Mekki ; M. Elloumi ; L. Arfa ; S. Lardon |Groundwater resources became a recognized enabler of important rural and socio-economic development in Mediterranean countries. However, the development of this groundwater economy is currently associated with an increased pressure on the availa[...]Article
En Algérie le climat se dérègle, leau se raréfie, que faire ? Alors pour répondre à cette interrogation, lhistoire de lhydraulique Algérienne et plus particulièrement les principaux ouvrages ancestraux ont été examinés dans ce papier. Evoque[...]Article
J. Schilling ; E. Hertig ; Y. Tramblay ; J. Scheffran |North Africa is considered a climate change hot spot. Existing studies either focus on the physical aspects of climate change or discuss the social ones. The present article aims to address this divide by assessing and comparing the climate chan[...]Article
Le présent papier examine le sujet dexploitation de la nappe inferoflux dans certaines régions du Sahara Algérien. Sur la base dun travail bibliographique, de collectes de donnés et des investigations effectuées sur des sites du sud Algérien d[...]Article
Two thirds of human water use is linked to agricultural practices including crop irrigation. Furthermore, excess irrigation leads to drainage problems. For this reason, reduced irrigation strategies need to be implemented to protect water resour[...]Article
With the growing population and climate change, increasing demands for water are intensifying competition between agricultural stakeholders. Since the mid-20th century, numerous crop models and modeling techniques have emerged for the quantitati[...]Article
In intensive agricultural systems, irrigation and nitrogen (N) fertilizer are the most important factors that influence crop production and N losses. This work aimed to evaluate the N best management practices using the calibrated and validated [...]Article
Climate change, in addition to reducing rainfall and increasing temperature, has led to a decline in water quality and increased groundwater salinity in Iran. These factors have a negative effect on crop yields. Therefore, the assessment of the [...]Article
L. Vergni ; F. Todisco ; B. Di Lena ; F. Mannocchi |In this study, the effectiveness of a bivariate analysis of agricultural drought characteristics for irrigation planning was evaluated. The case study was conducted in locations in central Italy and was based on olive crops which are widely grow[...]Article
In Iran, due to arid and semi-arid climate, groundwater resources play an essential role in food production, as well as domestic and industrial water supply. In recent years, increasing population, scarcity of surface water resources, and effect[...]Article
There is a growing consensus that sustainable development requires a behavioral change, forced by firm decision-making. However, existing decision-supporting tools are unlikely to provide relevant information, hampered by the complexity of combi[...]Article
