Ladies and gentlemen, In just about three weeks from now, on November 5, Washington State will likely pass a ballot initiative to label GMOs. Those numbers may come down a bit, but my hunch is this particular battle is lost. But as Churchill once said, it is certainly the end of the beginning. The strategy of fighting labelling state by state will have failed, and something new will have to take its place.
Messenger Variability is the only guarantee when it comes to the rainfall of the Sahel, the transitional zone between the parched Sahara Desert and the wetter savanna in the south.
The rains often arrive late, and sometimes they barely come at all. This can lead to devastating crop failures and famine in a region that relies heavily on the rain to grow most of its food.
Over the centuries, farmers across the Sahel have adapted to the fickle rainfall by growing crops such as millet, Religion and nourish crops, peanut, and cowpea, which are well suited to produce grain even during periods of drought stress. To confound the already dire problem, the population of the Sahel is growing and crop yields are not increasing in step.
Farmers preparing fields for planting in Ghezzehei In these nutrient-poor soils with low fertilizer input, the land is in desperate need of agriculture systems that can provide adequate yields and soil conservation with minimal inputs.
This research on soil hydrology in the Sahel is part of a larger project funded by the National Science Foundation investigating how traditional techniques practiced by some farmers can be adapted to further increase crop yields, even during times of drought stress.
We found that planting food crops together with the native woody shrub Guiera senegalensis can improve crop growth with minimal costs. Drinking from the same straw In some other agroforestry systems where crops are grown in association with trees, the trees can outcompete the crops for water and reduce the growth and yield of the crops nearby.
In our work, we investigated a process called hydraulic lift, also known as hydraulic redistribution, whereby the G. Hydraulic lift has been seen in environments that undergo periodic drought spells and has been shown to increase the ability of shallow roots to take up nutrients and maintain higher levels of transpiration and photosynthesis.
The process of hydraulic lift in G. Senegalensis was first observed by Dr. Fred Kizito and his colleagues as part of a similar National Science Foundation project in Our hypothesis was that each day, nearby pearl millet crops take advantage of some of this water that is drawn up by the shrubs.
To test the hypothesis of water transfer, we set up a field study in Senegal under the harsh Sahelian conditions.

This work is part of an ongoing research study looking at the growth of crops in association with the shrubs during the rainy cropping season. In order to create the necessary dry conditions we used irrigation to manipulate the amount and timing of water delivered for this experiment.
Millet grown for hydraulic lift tracer study under irrigation midseason without shrubs left with shrubs right. Nathaniel Bogie We monitored the soil moisture by using soil moisture sensors. Once we observed the daily drying and nightly re-wetting of the soil that is characteristic of hydraulic lift, we began our study.
Water pathway Hydraulic lift occurs when roots remove water from the upper soil layers during the day, causing the soil to dry out.
Then with the wet soil deep down and dry soil near the surface, the water moves up through the plant along a gradient, just like sucking water through a straw.
Once it gets to the upper soil layers, it is pulled into the dry soil surrounding the roots in the same way a dry sponge sucks up a spill on a countertop. Our hypothesis is that some of this water that is released from the roots is used by nearby millet plants. To carry out the experiment we attached bottles of water that included a chemical tracer to the deep roots of the shrub.
Then we collected aboveground samples of the shrub and crop stems growing nearby over a period of five days to see where the tracer water went. We found evidence of the tracer in a shrub on the first day after injecting the water, and shortly thereafter we found it in a crop growing nearby.
This finding strongly supports the idea that water moved up through the roots of the shrub and into the crop. The exact route from the shrub roots to the crop is a topic of further investigation, but we are confident that a pathway exists.
This combination of hydraulic lift and water transfer between species has long been hypothesized but rarely seen. It has never been observed as a component of an agroforestry system with such profound effects on crop production.
Our team consisted of American, French and Senegalese professors and graduate students, researchers from multiple African countries, and local farmers hired as field technicians.
We rented land from a farmer named Saliou Diouf who works closely with the researchers at the Senegalese Agricultural Research Institute. Saliou and his sons gave us invaluable perspective on cultivating millet and managing the shrubs.
Power of native plants The amount of water transferred between plants appears to be quite small. However, the quantity of water deposited may be much less important than the location where it is released.This lesson will seek to define intensive agriculture.
In doing so, it will highlight the concepts of subsistence versus commercialization. It will also define cash crops and agribusinesses.
From production to consumption, and even religion and culture, it is one of the most highly debated topics in the food system.
Meat production today causes harmful impacts on people and the planet. There is a lot of debate over how much meat should be part of a healthy diet.
Nov 13, · As an ancient fertility goddess, Ix-Chel was responsible for sending rain to nourish the crops. When fulfilling that function she was called “Lady Rainbow”. The word indigenous means “originated in”, and thus the term “indigenous religion” means “the original religion of a place.” Essentially this term is applied to the group of people of any religion, culture, or area.
The indigenous religion is a unique religion associated with the particular group. Tales from the Underworld: Cacao in Ancient Maya Religion We are indebted Every kind of tree, plant, leaf, flower, fruit and root featured in their symbols.
