www.GlobalBuckets.org It's easy to build and grow using the two 5-gallon bucket container growing system! Reduce global hunger with a low cost and simple way of growing food. This foolproof method of gardening is very similar to the excellent Earthbox® method. Like the Earthbox system, Global Buckets: 1) 80% reduction in water usage 2) 100% reduction in weeds 3) Takes very little time or effort. 4) No place to plant a garden? Great! This system works excellent on concrete...like on a rooftop in Calcutta. Unlike the Earthbox method, Global Buckets uses locally sourced free or low cost materials, ideal for developing nations.

Choosing the Hydroponic System That Is Right For You
Deciding which hydroponic system you will use will depends on how much money you will spend, what kind of plants you are able to grow, and how successful your garden will be. Therefore, it is imperative that you choose a system that matches your budget, needs, and experience. Hydroponic systems vary in what kind of equipment is required, how the nutrients are delivered, and what media can be successfully used.
The main kinds of the hydroponic systems are:
Wick Hydroponic System - The wick hydroponic system is the simplest and typically the most inexpensive system, and is thus commonly the choice of beginners to hydroponics. It is a "passive system", which means that it does not have any moving parts. It works by drawing the necessary nutrients into the growing medium from a reservoir with a wick. This should only really be used for smaller plants that do not require much nutrients or moisture, as the wicks cannot supply the plants with these things very quickly.
Ebb and Flow Hydroponic System - The Ebb and Flow system, which is sometimes referred to as the "Flood and Drain" system, is a much more advanced and complicated system. This system works by using a pump that is placed into the reservoir to regularly flood the grow tray with the nutrient solution and then draining it back into the reservoir. The pump floods the tray at regular intervals for a set period of time by using a timer.
In larger, more professional ebb and flow systems, the solution is pumped into a group of buckets. The advantage of the bucket or modular system is that each plant is grown in its own container and therefore can be moved or handled much more easily.
Nutrient Film Technique - This system delivers a constant flow of nutrients to the plants with a pump, so no timer is required. This system doesn't require a growing medium; the plants are simply suspended in a plastic tray with the roots dangling in a nutrient solution. While the lack of a growing medium may save you some money because you won't have to pay to replace the medium after every crop, this system is a little more high maintenance than most and the roots may dry out very quickly if something goes wrong with the pump and the flow of nutrients is interrupted.
Drip Irrigation Hydroponic System - In this system, a timer delivers the nutrient solution through the base of each plant through drippers. Continuous drip systems can be recovery or non-recovery, meaning that the used nutrient solution can either be returned to the reservoir or run off as waste. Recovery systems are more cost effective because they use the nutrient solution more effectively, but non-recovery systems require less maintenance because the pH balance and nutrient strength remains constant.
Aeroponic Hydroponic System - Aeroponics is a newer and more high tech method of hydroponic growing. Like the nutrient film technique, there is no growing medium. The plants are suspended with the roots in the air and the nutrients and moisture are supplied in the form of a mist. A timer ensures that the pump delivers a new spray of mist every few minutes. Like the nutrient film technique, it is imperative that the pump is always functioning correctly, because even a brief interruption can cause the roots to dry out.

Residential Fire Sprinkler System Advantages
Fire sprinklers have been used in the protection of many business establishments. But lately these fire protection systems have also gained popularity among home builders and home buyers alike. So what leads people to install fire sprinklers in their residences even if they have already installed smoke alarms? It is because smoke alarms merely alert occupants to a spreading fire in the house, but these devices cannot suppress it. Fire sprinklers on the other hand have proven to be very effective in controlling a fire and protecting people from its associated dangers.
According to the National Fire Protection Association, there were about 396,000 residential fires during 2005 in the United States. These fires had caused 3,055 civilian fire fatalities, 13, 825 civilian fire physical injuries, and .9 billion in property losses.
Studies conducted by the Federal Emergency Management Agency's United States Fire Administration show that thousands of lives could have been saved if residential fire sprinklers had been installed in those burned homes. The installation of a fire sprinkler system could have also prevented most of the fire related injuries and substantially reduced property damage.
Residential fire sprinklers are therefore very beneficial to both people's lives and properties. The advantages of these fire protection systems are further detailed below:
Quick response
The Underwriters Laboratories (UL) lists the latest available residential fire sprinklers. It features fire sprinkler heads with a quick response time that is faster than that of the standard commercial and industrial sprinklers. Due to their enhanced trigger mechanism, early suppression fast response (ESFR) residential fire sprinklers automatically activate quickly to control the fire before it can gain momentum.
Affordable cost
The current average cost for residential fire sprinklers is approximately .00 to .50 per square foot in the construction of new homes. This cost is expected to go down as home fire sprinklers get more popular and demand increases. Existing homes can also install a fire sprinkler system, but the cost is typically higher since the home has already been constructed.
Small size
Residential fire sprinklers are relatively smaller than the conventional commercial and industrial versions of these devices. Home fire sprinkler systems can also be inconspicuously installed and can be aesthetically coordinated with the color scheme of your home interiors.
Nominal installation work
During the construction of a new house or renovation of an existing one, installation of a residential fire sprinkler system will necessitate only a minimal amount of piping and labor since access to the walls, ceilings and attics is easily obtained.
Minimal water requirement
Residential fire sprinklers need less water than fire sprinkler systems designed for commercial and industrial buildings. Typically a residential fire sprinkler system can be linked to your home's main water supply.
Less costly piping requirements
The use of plastic PVC pipes has considerably lowered the piping costs. Plastic pipes are also more advantageous than metal pipes because they do not have rusting or threading problems typically associated with metal.
Individual sprinkler activation
The activation of the fire sprinklers is on an individual basis. This means that if the fire is in the kitchen, the nearest sprinkler will be the only one to activate and contain the fire in that area. Thus, water requirements and water-related property damage are both minimized.
Discounted insurance cost
Depending on the coverage type, underwriters offer discounts of about 5 to 15 % in home insurance premium to homeowners who have fires sprinkler systems installed. These values are even expected to increase in the future.
Residential fire sprinkler systems indeed offer an inexpensive, low maintenance, and inconspicuous option of fire protection. And on top of those advantages is the proven reliability of these devices in protecting your property and family from the hazards of fire. For the minimal cost of having a fire sprinkler system installed in your home, you can potentially increase the value of your property, gain discounts in your insurance premiums, and protect your family and possessions. A fire sprinkler system installed in your home is certainly a valuable investment that will become priceless should you have a fire in your home.

Managing Salinization: Institutional Analysis of Public Irrigation Systems
!±8± Managing Salinization: Institutional Analysis of Public Irrigation Systems
Salinization of soils is a major threat to irrigated agriculture and counteracts the targets of costly public infrastructure investments. In this study, salinization is regarded as the outcome of an institutional arrangement which impedes the effective implementation of well-known and well-established control measures be they technical, managerial or economic. In public irrigation systems neither the management units nor the farmers are offered any incentives towards the control of high groundwater levels and salinization if the management units are embedded in a highly centralized non-market institutional setting. The author answers the question under which conditions management units and irrigators are active in halting and reversing the process of salinization.
