Water Harvesting and Management

We are living in a rather confusing era. In certain times of the year or certain parts of the world, flood and thunderstorms deluge the land without mercy; then in other times or places, there is nary a drop of drinkable water.

This is not only happening to the developing countries but in our own backyards too, from frequent California drought to submerging gulf coasts in Florida and Louisiana.

No water, no food, whether conventional or alternate food source!

Even a year 1 student knows that water is the essential factor of all living things, however, fear of diminishing usable water has become increasingly heard. This situation is not only affecting farming sector but also urban living when the water tabs run dry and the food price is escalating.

Agriculture utilizes 70 percent of total global water consumption. At this rate, it is worrisome how the world is going to have sufficient water to feed projected 9 billion people by 2050 as surface water is running low or polluted and ground reservoir water is increasingly tabbed.

The question of whether we can achieve better water management system to feed the whole world is no longer pertinent for we have no choice but to do it. World organizations, leading universities and research centers, governments and individuals have to come together to work out a sustainable water collection, utilization, and management systems. Water collection and management is a most tangled web of countless factors with each factor affects the water situation negatively or positively.

Studies conducted by leading institutions such as Columbia Water Center of Columbia University and the World Organization have indicated there are sufficient water to cater for human needs if managed properly. The broad strokes recommendations from these institutions are as followed:

Suitable Crop Growing
It is crucial to match the availability of water, biophysical environment, people social and economic capability with suitable crops for the maximum return. The crops grown has to be able to self-sustaining for local economy at the minimum. The good old day of growing water-insatiable plants in savannah region by piping in water to keep the plants alive is probably not the best practice. Looking at all possible alternate food source that are environment economical will be the way going forward.

Water Infrastructure and Water Technology Investment
One of the key success of the Roman Empire was their recognition of the importance of water supply and management. While their water infrastructure and aqua engineering were well developed and second to none, the world today is lagging in both. Unless investment in these areas takes priority and urgency, precious drinkable water will continue to be wasted.

Multiple Recycling of Water
Most drinkable water is utilized only once which is a complete waste of natural resources. In Japan, it is very common to see toilet bowls with sinks mounted directly on top of the water tank. The water used to wash hands flow directly into the tank for later flushing. This is one example of reusing water in a consistent manner. Even that, the water is only used twice. As technology advances, better water harvest and treatment may be the solution to water shortage. A flood management could well be a water resource management opportunity rather than the current disposal management practice.

Carrot Sticks
A radical change from the norm or past farming practice is unlikely to happen without clear government intervention in the form of education, incentives or aids. In Africa and India where most farmers are not well connected to the outside world, government leads are extremely important. Even in the urban area, if a change greatly inconvenient the people for the benefit of future generations, the majority of the people is not going to embrace the change without clear regulations from the government. With proper encouragement, innovation in water conservation and management can materialize faster than later.
As we inch towards 2050, the crucial point to take away is that we can no longer take water- the fluid of life, for granted. Better utilization, recycling, and innovation have to take precedent over others. What have been long practiced may no longer suitable, new thoughts and economical ways have to emerge. Without effective water harvest, the society will eventually perish.

Pulses for The Mass

uring the 2013 Sixty-eight annual meet of the United Nations General Assembly, the year 2016 was designated as the International Year of Pulses (IYP).

What is so import about pulses that the United Nations General Assembly compelled to declare 2016 as the Year of Pulses? Other than the familiar meaning of heart rhythmical throbbing or wave pulsation, pulses are the collective name for the dried seeds of the legume family including lentils, various types of beans, chickpeas and dried peas.

Green beans are a type of pulses.

UN hopes the declaration of IYP is able to increase public awareness of the health benefits of pulses as part of the sustainable food production plan to secure food supply and nutrient needed. IYP 2016 aims to foster connections throughout the food supply chain for a better utilization of plant-based proteins, increase production of pulses globally, to better employ suitable crop rotations and to tackle issues associated with the crop trading.

The role of legumes in the advancement of civilization is undeniably important although they are often taken for granted. Since prehistoric, legumes have provided the human with vegetable, grains and pulses, forage and winter silage for the livestock, and green manure for soil enrichment. Their root nodules hosting nitrogen-fixing ground bacteria are particularly beneficial in fertilizing the land and facilitating crop rotation.

Pulses of legumes are rich in protein, complex carbohydrates, dietary fiber, essential minerals but low in fat. Chickpeas and lentils, widely consumed pulses in India continent, are often promoted as very affordable super foods for very good reasons. Of Daily Value requirement, a 100g serving of chickpeas provides 38% of protein, 68% of dietary fiber, 34% of Iron, 28% of Magnesium, 25% of Potassium, 0% cholesterol and 9% total fat. A 100g serving of chicken breast, on the other hand, provide 62% of protein, 0% dietary fiber, 30% VitaminB-6, 7% Magnesium, 28% cholesterol and 5% total fat.

Cultivated legume plants are used for many purposes, as grain, forage, medicine, blooms, green manure/fertilizer, and even as timber sources.

Grounded beans can be used to replace other expensive ingredient without sacrificing on nutrient, taste or texture. For example, carob flour can be used to replace cocoa flour in chocolate cookies. Flour grounded from other beans can also be used to replace common flour in making cakes and bread.

There is another notable advantage of pulses. As they are dried produces with long shelf-live, they can be easily and economically stored and transported throughout the world when needed. Transported pulses are versatile enough they can be used as food or as seeds for future generation. The variety of legume plants is so numerous that there are species suitable to be grown in practically any region with human inhabitant, be it tropical area, temperate regions, savannah or deserts.

As the weather becoming increasingly unpredictable, soil natural nutrient depleting and agriculture land limited, legume plants are an important factor in ensuring sufficient and quality food source for the projected 9 billion people in 2050.
