STUDY OF CHANGES IN SOIL MOISTURE AND SALINITY UNDER PLASTICMULCH AND DRIP IRRIGATION IN PISTACHIO TREES

Journal of nuts (2016)

Nasser Sedaghati Amin Alizadeh Hossein Ansari Seyed Javad Hosseinifard

In this study, changes in soil moisture and salinity contents in drip irrigation combined with white and black plastic mulches compared to no mulch (control) was evaluated. The experiment was carried out in two commercial pistachio orchards (Ohadi cultivar) with irrigation frequencies of 8 to 12 days with a total water consumption 4100 and 6170 m 3 ha −1 . The study was conducted in a complete randomized block design with three replicates from 2014-2015. Results showed that plastic mulches significantly affected the studied parameters, such as dry yield and water use productivity (WUP). The WUP in plastic mulch treatments increased from 36% to 100% compared to the control. On the other hand, soil moisture content in plastic mulches were up to 12% higher than control in irrigation intervals in both orchards. Moisture content equations between two consecutive irrigations obtained in depth of the maximum root development (25 to 75cm). Proper irrigation frequency in pistachio trees with sandy loam to loamy sand soil was determined based on the derived equations and PWP and RAW in soil experimental plots. The frequency was six to eight days in the case of no mulch, and in the use of plastic mulch, it was 11 to 15 days. The results showed that the use of plastic mulch decreased the soil surface salinity from 30.8% to 51.8% compared to the control. The amount of water consumption, irrigation frequency, soil texture and sampling points affected the soil surface salinity. The average salinity of 0-120cm soil depth was reduced from 20.4% to 27.7% compared to the no mulch treatment. The mulch color did not have a significant effect on any of the parameters.

Career exploration among hospitality workers during the COVID-19 pandemic – insights for future

International Journal of Human Resource Development Practice Policy & Research (2024)

Deepu Kurian Amin Alizadeh Bhagyashree Barhate

Abstract The purpose of this paper is to analyse the career exploration trends among hospitality employees during the COVID-19 pandemic, gain insights into the labour shortages, and provide implications for the future of the hospitality industry’s workforce. The pandemic decimated local, national, and international mobility, decimating the hospitality industry. All the hospitality organizations downsized, furloughed and/or reduced the compensation of their employees to keep up with turbulent times. Post-pandemic, the hospitality industry is ready to rehire the employees that were laid off or furloughed during the pandemic. However, the employees have not returned, and the industry is undergoing chronic labour shortages. Using the tenets of the career exploration theory, we collected data from 198 individuals who were/are employed in the hospitality industry about their career exploration tendencies during the pandemic. The results showed heightened levels of career exploration within and outside the hospitality industry; it is imperative that HRD practitioners should respond to the changing needs of hospitality industry employees. The study contributes to the lifespan approach to career exploration by highlighting self-exploration and environmental exploration by hospitality industry employees during the pandemic irrespective of demographic differences.

A human resources development professional's framework for competencies during COVID‐19 and unrest

New Horizons in Adult Education and Human Resource Development (2022)

Noeline Gunasekara Bhagyashree Barhate Amin Alizadeh Rosemary Gaza Capuchino

The purpose of this article is to explore the competencies required and exhibited by human resource development (HRD) professionals during a crisis. Keeping the current COVID-19 pandemic in the foreground, we examined the industrial, change management, and crisis management literature to illustrate how HRD professionals successfully helped their organizations overcome organizational challenges imposed by the pandemic. We propose some essential competencies that HRD professionals, as change agents, need to support organizations to survive a crisis in the long term. At the core of our model is learning, unlearning, and relearning. HRD professionals can develop the core competencies in conjunction with essential competencies such as flexibility, agility, thoughtfulness, effective communication, critical thinking, and creativity. Through our conceptual competency model, we propose that HRD can prepare its professionals holistically to support leaders and employees during a crisis.

Prediction of Annual Evaporation Change in Dry Regions Using the Budyko-type framework (Case Study of Neishaboor-RokhWatershed)

Iranian Journal of Irrigation & Drainage (2016)

Ameneh Mianabadi Amin Alizadeh Seyed Hossein Sanaei Nejad B Ghahraman Kamran Davary

Prediction of the water balance components, including actual evaporation is important for water resources management and climate change adaptation. Physically-based or distributed hydrological models are too complicated and they need lots of data as inputs to estimate the water balance components. Also the accuracy and the quality of the inputs can affect the accuracy of the models’ prediction. In some cases, it is not needed to have an accurate estimation of the water balance components and a primary estimation of annual evaporation and runoff is adequate for the management of the catchments. For these purposes, the conceptual lumped models were developed for the primary studies of hydrology. One of the most applied lumped models is developed based on Budyko hypothesis. Budyko curves were applied for the steady-state catchments in which the soil water storage is negligible. In the Budyko framework, a new equation (Greve et al., 2016)was developed to estimate evaporation in non-steady-state situations where the soil water storage cannot be negligible. In this study, the new proposed model was calibrated for the non-steady-state catchment of Neishaboor-Rokh using the precipitation, potential evaporation and actual evaporation and then using the calibrated equation, actual evaporation was estimated for the historical (1971-2005) and future (2016-2050) period of CORDEXproject. Based on the actual evaporation from SWAT model, Greve et al. model parameters (y0 and k) were 0.24 and 1.54, respectively. The results showed that, under climate change, the precipitation rate would decrease by 0.48% and mean temperature, potential evaporation and actual evaporation would increase by 11.25%, 4.66% and 2.11%, respectively.

A framework for organizing participatory Water Planning and Management Team (WPMT)

International Journal of Engineering and Technology (2019)

Mohammad Salarian Kamran Davary Amin Alizadeh Mohammad Lagzian Mohammad Fazeli

The need to properly manage water resources has become increasingly important as states strive to improve their socio-economic and social-ecological situation.No actor can be expected to understand sufficiently the multiple interdependent physical, ecological, social, cultural and political processes that govern the behavior of water resources systems.Broad-scale, multi-governance level, participatory water management processes intended to aid collective decision making and learning are rarely initiated, designed, implemented, and managed by one actor.Participatory water management processes mostly emerge from some form of collective planning and organization activities because of the stakes, time, and budgets involved in their implementation.Despite the potential importance of these collective processes for managing complex water-related social-ecological systems, little research focusing on the projectteams that design and organize participatory water management processes has ever been undertaken.In this text we have begun to fill this gap by introducing and outlining the concept of a participatory processbyreview previous studies.The analyticalframework suggested in this text is organized around eight components; Who are Stakeholders, Drivers of stakeholder engagement in the water sector, Stakeholder Analysis, Stakeholders' interactions, Level of participation, Organizational structure, When stakeholder engagement and effective participatory processes.

A global Budyko model to partition evaporation into interception and transpiration

Ameneh Mianabadi Miriam Coenders‐Gerrits Pooya Shirazi B Ghahraman Amin Alizadeh

Abstract. Evaporation is a very important flux in the hydrological cycle and links the water and energy balance of a catchment. The Budyko framework is often used to provide a first order estimate of evaporation, since it is a simple model where only rainfall and potential evaporation is required as input. Many researchers have tried to improve the Budyko framework by including more physics and catchment characteristics into the original equation. However, this often resulted in additional parameters, which are unknown or difficult to determine. In this paper we present an improvement of the previously presented Gerrits' model (Analytical derivation of the Budyko curve based on rainfall characteristics and a simple evaporation model in Gerrits et al., 2009 WRR), whereby total evaporation is calculated on the basis of simple interception and transpiration thresholds in combination with measurable parameters like rainfall dynamics and storage availability from remotely sensed data sources. While Gerrits' model was investigated for 10 catchments with different climate conditions and some parameters were assumed to be constant, in this study we applied the model on the global scale and fed with remotely sensed input data. The output of the model has been compared to two complex land–surface models STEAM and GLEAM, as well as the database of Landflux-EVAL. Our results show that total evaporation estimated by Gerrits' model is in good agreement with Landflux-EVAL, STEAM and GLEAM. Results also show that Gerrits' model underestimates interception in comparison to STEAM and overestimates it in comparison to GLEAM, while for transpiration the opposite is found. Errors in interception can partly be explained by differences in the interception definition that successively introduce errors in the calculation of transpiration. Comparing to the Budyko framework, the model showed a good performance for total evaporation estimation.
