Assessing potential of water rights and energy pricing in making groundwater use for irrigation sustainable in India
Groundwater emerged as a major source of irrigation in India during the mid-1970s. However, a large expansion in well irrigation due to a massive rural electrification programme, government policies of promoting private tube well construction and large subsidies on electricity for agricultural use resulted in groundwater over-abstraction in many semi-arid and arid regions of India. In addition, ...

Modeling irrigation management strategies to maximize cotton lint yield and water use efficiency
Increasing pumping costs and declining well capacities in the Southern High Plains compel producers to seek irrigation strategies to maximize yield and water use efficiency (WUE), which is the ratio of yield to evapotranspiration (ET). Cotton (Gossypium hirsutum L.) is suited to deficit irrigation using wells ranging from 0.29 to 0.93 L s–1 ha–1 capacity to supply limited, 2.5 mm d–1, to ...

Opportunities for saving and reallocating agricultural water to alleviate water scarcity
As water scarcity worsens globally, there is growing interest in finding ways to reduce water consumption, and for reallocating water savings to other uses including environmental restoration. Because irrigated agriculture is responsible for more than 90% of all consumptive water use in water-scarce regions, much attention is being focused on opportunities to save water on irrigated farms. At ...

Group method of data handling (GMDH) application for modelling of mechanical properties of trees irrigated with wastewater
Experiments have been carried out to identify the mechanical properties of trees irrigated with wastewater, as well as mathematical modelling of measurement results via the group method of data handling (GMDH) method. Eucalyptus trees were cultivated and irrigated with processed wastewater from a treatment plant. Characteristics of wood quality (axial compression and bending, etc.) were measured ...

GWT- Agro-Z media enhanced plant growth and reduces fertilizer usage in Nursery - Case Study
This case outlines the benefits and advantages of using GWT series Agro-Z medium in an agriculture plant nursery application. This particular large nursery was challenged with brackish water and salty soil. The plant growing operations were suffering due to lack of plant growth. Genesis Water Technologies, experienced in agriculture water treatment solutions provided both a water treatment ...

Spectral water indices for assessing yield in elite bread wheat genotypes under well-irrigated, water-stressed, and high-temperature conditions
The objective of the present work was to determine the relationship between spectral reflectance indices (SRI) and yield in spring wheat (Triticum aestivum L.) in NW Mexico in three environments (irrigated, water-stress, and high-temperature). The SRI were classified into vegetative indices (three indices) and water indices (five indices). The SRI were determined at booting, heading, and ...

Improved Agricultural Irrigation Scheduling Using a Soil Water Content Sensor - Case Study
Abstract The key to scheduling irrigation timing and amounts is determining moisture depletion in the soil. Two common methods include tracking crop evapotranspiration (ETc) and tracking the water content with a sensor buried in the soil. In Colorado, a popular online tool that estimates the ETc for a variety of well-irrigated crops is the Colorado Agricultural Meteorological Network (CoAgMet). ...

The effect of rigid scheduling on productivity and water-use of potatoes (Solanum tuberosum L.) grown under small-scale irrigation
This paper evaluates the results of a study highlighting the effect of rigid scheduling on crop water use and soil water extraction patterns, crop coefficients, crop response functions and water-use efficiency (WUE). The cumulative Penman potential evapotranspiration (Etp) at the end of the season reached around 400 mm and the total depth of water applied between planting and harvest through ...

Irrigation Application Management
The Irrigation Applications management takes all measurements of the inlet discharge and pressure at the pivot point and pivot end. Especially when the ground is uneven, where we take readings at the highest point. Preferably, this pressure value should be at least 5 PSI higher than the rated value of the pressure regulator, to ensure safety and proper operation, as the regulator must be ...

Could food shortages bring down civilization?
One of the toughest things for people to do is to anticipate sudden change. Typically we project the future by extrapolating from trends in the past. Much of the time this approach works well. But sometimes it fails spectacularly, and people are simply blindsided by events such as today’s economic crisis. For most of us, the idea that civilization itself could disintegrate probably seems ...

Watering Scarcity: Private investment opportunities in agricultural water use efficiency
This report was prepared by Rabobank in collaboration with the World Resources Institute. In many regions around the world, demand for fresh water now outstrips renewable supplies. Water scarcity is projected to worsen considerably due to a combination of factors such as population increase, higher incomes and changing lifestyles, pollution, and climate change. Agriculture is by far the biggest ...

Taxpayer dollars subsidizing destruction
One way to correct market failures is tax shifting—raising taxes on activities that harm the environment so that their prices begin to reflect their true cost and offsetting this with a reduction in income taxes. A complimentary way to achieve this goal is subsidy shifting. Each year the world's taxpayers provide at least $700 billion in subsidies for environmentally destructive activities, such ...

New Era of Food Scarcity Echoes Collapsed Civilizations
The world is in transition from an era of food abundance to one of scarcity. Over the last decade, world grain reserves have fallen by one third. World food prices have more than doubled, triggering a worldwide land rush and ushering in a new geopolitics of food. Food is the new oil. Land is the new gold. This new era is one of rising food prices and spreading hunger. On the demand side of the ...

How does participatory irrigation management work? A study of selected water users' associations in Anand district of Gujarat, western India
Measuring the performance of water users' associations (WUAs) is a complex task. Literature associates a large number of parameters with their success and failure. This paper presents an in-depth study of two WUAs that are considered to be functioning well by the irrigation department in Anand, India. It discusses some new issues and innovations being tried out in Anand, namely: (1) ...

Climate, vulnerability and farming: a preliminary study among Australian food growers
The present study examines climate change, vulnerability to climate, and other environmental challenges from the perspective of 80 horticulture operators from different Australian states. Vulnerability in the form of storms and droughts are respondents’ main environmental concerns; in some cases, the impact of wildlife displacement is affecting their production outputs. In addition, substantial ...

Farming Innovation: From Ammonia to AgTech Software
Just over a century ago, the Haber-Bosch process was invented in Germany, enabling the scalable production of copious amounts of ammonia for the very first time. This 1910 Eureka! moment meant farmers could fertilize their crops unlike ever before, growing food on a massive scale. So massive, in fact, a population explosion ensued – humankind went from 1.6 billion in 1900 to 7.7 billion 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 ...
