“…Climate change and agricultural malpractices rising groundwater depletion are major concerns globally and more acute in the developing countries of Asia (Ahmed et al 2014;Neupane et al 2021) resulting in water scarcity for crop production, especially in dry seasons (Jahan et al 2010;Hasan et al 2018). Freshwater scarcity through groundwater depletion is an acute environmental phenomenon threatening global food safety by unfavorably impacting justifiable crop production (Ullah et al 2017;Ilyas et al 2021).…”

“…These demands finding watersaving methods to decrease water use in agriculture while boosting yield to assist a rising population (Carrijo et al 2017). Future climate forecasts direct towards more uncertainties regarding irrigation water accessibility; regular incidents of drought will aggravate sustainable and precise application of irrigation water (Gosling and Arnell 2016;Neupane et al 2021). In Bangladesh, total rainfall during the tomato growing season is irregular, ranging from 150 to 500 mm in total.…”

The deficit irrigation offers water savings potential that is becoming popular in arid and semi-arid regions reducing freshwater use over time. A two-year factorial experiment was conducted to evaluate growth, yield and water productivity of tomato under water deficit irrigation of the drip and furrow method. The experiment was carried out in a split-plot design with drip irrigation and furrow irrigation as main plot treatments, and soil moisture regimes (0, -10, -20, -30 kPa) as subplots. Data were collected on growth parameters, physiological traits, yield and water productivity of tomato. The results showed that physiological traits, yield, and water productivity were significantly influenced by irrigation system and soil moisture regime. The drip irrigation system with -10 kPa soil moisture regime reduced total water input by 22.6% and 19.8% and gave 28% and 22% higher fruit yields in 2020 and 2021, respectively, compared with furrow irrigation system. Plant growth was higher and flowering occurred earlier (3 days) with drip irrigation system than with furrow irrigation. When the soil water content was -10 kPa, drip irrigation performed significantly better than for other soil moisture regimes by improving physiological and phenological attributes, and thereby, advancing tomato growth and fruit yield. Thus, a drip irrigation system with soil moisture regime -10 kPa could reduce total water input through precise irrigation, maximizing tomato yield and water productivity.

In recent years, Asia and the Pacific have been ravaged by strong typhoons that caused widespread destruction. The powerful winds from these typhoons ripped off roofs, windows, doors and walls from houses, and destroyed trees and other vegetation, leaving a vast amount of wooden, metallic, plastic, and glass debris and waste scattered across a wide area. Proper management of disaster waste is a critical task during the initial phase of disaster recovery. It is essential for coastal cities that are frequently affected by typhoons to have adequate capacity for post-disaster waste management. This capacity development project aimed to contribute to this end by providing appropriate knowledge and training to government and non-government stakeholders. The project was implemented in Lautoka City, Fiji and Makati City, Philippines, with the support of four prominent universities. In total, six training sessions were conducted under the project. The primary outputs of this project are the disaster waste management contingency plans of the two participating cities. The project team disseminated information about the capacity development project through the project website and through presentations in academic conferences, webinars, workshops, training, non-academic conferences, and radio guest appearances.
