Impact of agricultural water reallocation on crop yield and revenue: a case study in China
Our study area in the People's Victory Canal Irrigation District of Henan Province in China has been transferring agricultural water to the city for municipal use. This study starts with an examination of the impacts of irrigation frequency, irrigation water sources, and irrigation water supply performance on crop yield and net crop revenue, using data from a survey of 182 households in the ...

AquaCrop model simulation under different irrigation water and nitrogen strategies
On a global scale, irrigated agriculture consumes about 72% of available freshwater resources. Deficit irrigation can be applied in the field to save irrigation water and still lead to acceptable crop production. The AquaCrop model is a simulation model for management of irrigation and nitrogen fertilizer. This model is a new model that is accurate, robust and requires fewer data inputs ...

Irrigation water requirements for seed corn and coffee under potential climate change scenarios
The impact of potential future climate change scenarios on the irrigation water requirements (IRRs) of two major agricultural crops (coffee and seed corn) in Hawai'i was studied using the Irrigation Management System (IManSys) model. In addition to IRRs calculations, IManSys calculates runoff, deep percolation, canopy interception, and effective rainfall based on plant growth parameters, site ...

Irrigation Systems 101: What you need to know
In the perfect scenario everyone could rely on rainwater for their farming practices, but this is not always the case. This is why employing the right choice from the different irrigation systems available is crucial for agricultural success. Irrigation systems are basically an artificial way to provide water to fertile soil for agricultural purposes. Crop irrigation is necessary to overcome ...

Cattail plants’ Biomass as a bulking agent in sewage Sludge composting and the effect of the produced Compost on cattail plants’ Growth
In every Greek island there is at least one town with more than 20,000 inhabitants. Several smaller towns and villages range from a few hundreds to a few thousands in population. Usually in the larger towns there are sewage treatment facilities providing at least secondary treatment of wastewater. In most cases the effluent produced is drained to the sea and the sludge is dumped in landfills. In ...

Novel simulation-based algorithms for optimal open-loop and closed-loop scheduling of deficit irrigation systems
The scarcity of water compared with the abundance of land constitutes the main drawback within agricultural production. Besides the improvement of irrigation techniques a task of primary importance is solving the problem of intra-seasonal irrigation scheduling under limited seasonal water supply. An efficient scheduling algorithm has to take into account the crops' response to water stress at ...

Water
Water is the most valuable asset on earth, which determines to a significant extent the development of life in all corners of the world. 95% of the amount of water on earth is chemically bound in rocks making it impossible to utilize and be part of the hydrological cycle. Of the remaining 5%, 97% is saline found in oceans and seas, while the remaining 3% is distributed: • 2,37% in ...

Climate change, a storm in the coffee cup
Coffee is the third most consumed beverage in the world after water and tea. Food and Agriculture Organization (FAO) confirms ‘Coffee is the most widely traded tropical product, with up to 25 million farming households globally accounting for 80 per cent of worlds output’. In 2020, 87% of the global coffee production originated from the top 10 biggest coffee-producing nations, says ...

To Meet Agtech’s New Movers and Shakers, Look Beyond Buenos Aires
Last November, Arable participated in Silicon Valley Argentina in Rosario, a forum co-organized with Fundación CEDEF, Chacra Media Group, and Silicon Valley Forum. We’ve been to a number of ag shows in the US, and have never seen anything that compares to the caliber of this event. The best part was its forward-thinking focus on ‘the next generation of ag’: It was more ...
