The modeling of yield response to water is expected play an increasingly important role in the optimization crop productivity (WP) agriculture. During 3 yr (2004–2007), field experiments were conducted assess stress quinoa ( Chenopodium Willd.) Bolivian Altiplano (4000 masl) under different watering conditions (from rain fed, RF, full irrigation, FI). Crop physiological measurements and comparisons between simulated observed soil content (SWC), canopy cover (CC), biomass production, final...
SUMMARY AquaCrop, the FAO water productivity model, is used as a tool to predict crop production under limiting conditions. In first step AquaCrop was calibrated and validated for barley ( Hordeum vulgare L.). Data sets of field experiments at seven different locations in four countries (Ethiopia, Italy, Syria Montana, USA) with climates years five cultivars were model calibration validation. The goodness-of-fit between observed simulated soil content, green canopy cover, biomass grain yield...
Abstract Salt intrusion in estuaries can pose a threat to drinking water extraction, irrigation, industries, and ecology. Key factors influencing the salt length include freshwater river flushing vertical mixing. This study investigates potential of estuarine sand dunes, that is, large‐scale rhythmic patterns, serve as nature‐based solution mitigate intrusion. To this end, we adopt two‐dimensional (2DV) modeling approach, which numerically solves flow transport an idealized single‐channel...

This paper presents a procedure in which the water-driven water productivity model AquaCrop was fine-tuned and validated for maize local conditions Zimbabwe then applied to develop sowing management options decision support. Data from experiments of 2 seasons Harare 5 other sites around were used calibration validation AquaCrop. Model parameters such as reference harvest index (HIo); canopy growth coefficient (CGC); early decline normalised biomass (WPb*) adjusted during calibration....
To date, phosphorus recovery as struvite in wastewater treatment plants has been mainly implemented on water phases resulting from dewatering processes of the sludge line. However, it is possible to recover directly phases. Besides minimising return loads line line, placing such a process within claimed offer advantages higher potential, enhanced dewaterability treated sludge, and reduced speed scaling pipes devices. In plant at Leuven (Belgium), full-scale digested tested for 1 year....
SUMMARY At various locations in North Ethiopia (Tigray), field experiments were conducted from 2006 to 2009 assess the crop response water stress of tef ( Eragrostis (Zucc.) Trotter) under rainfed, fully irrigated and deficit irrigation conditions. Observed soil content (SWC), canopy cover (CC), biomass production B ) final grain yield Y used calibrate validate AquaCrop for tef. Data an experiment a controlled environment 2008 also considered calibration process. Simulations SWC, CC,...
One of the options to recycle phosphorus (P) in wastewater sector is recover it as struvite crystals from digested sludge. Measurements on a full-scale demonstration plant Leuven, Belgium, yielded first indication profitability recovery, function different variables such incoming PO43− concentration, MgCl2 dosing, improved dewaterability, etc. An uncertainty and sensitivity analysis was carried out. Although possible improvement sludge dewaterability when recovering has positive economic...
Abstract Reviewing the situation of quinoa production in southern Bolivia, Jacobsen (2011, J. Agron. Crop Sci. 197: 390) argues that booming export market has a negative effect on environment and home consumption quinoa, thereby leading to an environmental disaster region. In view scarcity scientific knowledge rapid social dynamics region, we consider Jacobsen’s review misrepresents Bolivia. Specifically, argue (i) data presented by do not support any drop crop yield supposed reflect soil...
To obtain updated data on and assess the contribution of trypanosomosis to disease burden cattle kept at edge Hluhluwe-iMfolozi Park, a survey was conducted Mvutshini Dip. Use made purposeful sampling strategy by restricting animals that livestock owner considered be in poor condition. Of total 76 blood samples collected, 26 were parasitologically positive 46 PCR / RFLP. Almost all infections due Trypanosoma congolense savannah subgroup. A 63 had PCV < 24 % anaemic. Results from show...
