Delta drainage and irrigation system, complex multifunction hydraulic system analysis - Case Study
Introduction: Delta, British Columbia is located in the Fraser River delta on the shores of the Pacific Ocean, just south of the City of Vancouver. Delta comprises mostly agricultural land, with typical ground elevations near sea level. Levees protect the area from potential floods from the Fraser River and tidal surges from the Pacific Ocean. Of the 13,500 hectares (ha) watershed, 6,300 ha is ...

Five benefits of agricultural smart irrigation
Population growth and an increase in irrigated agricultural land lead to a greater need for water and energy, at a time when global warming and rising greenhouse gas emissions are posing a real environmental challenge. In this context, the benefits of smart irrigation, i.e., using the exact amount of water needed for each crop, help to optimize this scarce resource. If we take a closer look at ...

Accounting for the market and non-market values of multifunctional outputs in evaluating water transfers to non-agricultural uses: empirical evidence from Taiwanese rice production
Increased demand for water for municipal and industrial uses throughout Taiwan has intensified the pressure to re-allocate water from agricultural to non-agricultural uses. The full policy implications of such water transfers must not only account for the value of lost agricultural production and income, but also any loss in the social value of multifunctional benefits from agricultural ...

Efficiency concept under stochastic consideration of water value in irrigated agricultural land in Crete, Greece
Water is an increasingly scarce and valuable resource. It is generally accepted that there is a finite supply of water. As economies grow there is an increasing demand for water. The application of water to agricultural lands for irrigation is one of the essential uses of this natural resource in many areas. There is competition among agriculture, industry, and human consumption for the ...

The optimization of the paddy field irrigation scheduling using mathematical programming
In planting rice, a significant amount of irrigation water is required to prepare the farmlands and do transplanting and this is directly related to the number of machines and workers available; that is, the more the length of plowing and transplanting process due to the lack of required machinery and labor, the more the water volume consumed. Therefore, in such conditions, it is important to ...

Key Challenges for UK Irrigation in Agriculture
Irrigated agriculture is an integral part of the rural economy, but increasing water use creates several challenges, not least meeting the food demands of a growing population while using as little water as possible to save energy. In this article, we’ll look at the key challenges for UK irrigation in agriculture, to shed light on what the industry must do to preserve itself. ...

The water we eat
Agriculture imposes a heavy and growing burden on Europe's water resources, threatening water shortages and damage to ecosystems. To achieve sustainable water use, farmers must be given the right price incentives, advice and assistance. Food is intrinsically bound to human wellbeing. Besides the importance of good food for good health and the pleasure we derive from eating, agricultural ...

Urban and agricultural pesticide inputs to a critical habitat for the threatened delta smelt (Hypomesus transpacificus)
The Cache Slough complex is an area of tidal sloughs in the Sacramento‐San Joaquin River Delta of California, and is surrounding by irrigated agricultural lands. Among the species of concern in the area is the delta smelt (Hypomesus transpacificus), a federally‐listed threatened species. Releases of the organophosphate insecticide chlorpyrifos and pyrethroid insecticides were examined to ...

Fertility status, trace elements and heavy metal pollution of agricultural land irrigated from the Gediz River
The effect of the Gediz River, polluted by industrial and domestic wastes, on fertility status and trace elements and heavy metal pollution of agricultural land irrigated from this river was investigated. For this purpose, soil samples were collected in August 1998 between the source of the Gediz River (Murat Mountain) and its mouth (Aegean Sea). Soil samples were collected from 12 different ...

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 ...

Ancient water robotics and Abou-l Iz Al-Jazari
Although water resources have been developed throughout the centuries for the service of different civilizations, at different scales and in different regions, their use in automation has been conceived only recently. Research into the history of water from an automation point of view has led to some unknown or hidden facts. Starting from the ancient Greek period before the prophet Christ and ...

Nitrogen recovery from source-separated human urine using clinoptilolite and preliminary results of its use as fertilizer
The use of source separated human urine as fertilizer is one of the major suggestions of the new sanitation concept ECOSAN. Urine is rich in nitrogen, phosphorus and potassium which act as plant nutrients, however its salinity is high for agricultural and landscape purposes. Moreover, characteristics change significantly throughout storage where salinity increases to higher values as the ...

Upgrade Your Farm With Government Grants
The cost of upgrading farms using modern technology can be significant. Fortunately, there are a number of Canadian government grants for farmers, ranchers, and producers to alleviate these financial burdens. Technology plays a major role today in enhancing a farm’s production efficiency, yields and profits over the ...

The need for a professional network of agricultural and biosystems engineers in Africa
Agricultural productivity in Africa remains the lowest in the world, but recent concerns about food insecurity, rising food prices and resource depletion have spurred world–wide interest about the role of African agriculture in feeding Africa and the world. Majority of world's uncultivated agricultural land is in Africa, yet the capacity to harness this resource remains limited due partly ...

Project - FP202 - Upscaling Ecosystem Based Climate Resilience of Vulnerable Rural Communities in the Valles Macro-region of the Plurinational State of Bolivia (RECEM-Valles)
The Los Valles Macro-region in the landlocked, South American state of Bolivia is threatened by increasing temperatures and precipitation instability. Furthermore, frost intensity and hail events have put pressure on the delicate water systems in the valley. Climate change increases the vulnerability of water systems and the agricultural sector in the region, particularly smallholder farmers ...

Soil Sensor-driven Precision Agriculture
For centuries, farmers have relied on intuition, experience, and a hint of superstition to nurture their crops. While time-honored technologies still have value, the modern agricultural landscape has a powerful ally: precision agriculture. At the heart of this revolution is a silent orchestra of information-gathering heroes: soil sensor. Whispering wisdom from the earth: Gone are the days of ...

What is the difference between traditional and modern farming?
Agricultural systems in various parts of the world have evolved due to technological advances and increasing human knowledge. It develops from primitive agriculture, traditional agriculture to modern agriculture. At that time, hunting and gathering activities are familiar techniques for humans. Conventional agriculture started since humans began to settle and cultivate in one location. This ...

Rising Temperature, Rising Food Prices
Agriculture as it exists today developed over 11,000 years of rather remarkable climate stability. It has evolved to maximize production within that climate system. Now, suddenly, the climate is changing. With each passing year, the agricultural system is becoming more out of sync with the climate system. In generations past, when there was an extreme weather event, such as a monsoon failure in ...
