: The Budyko curve is an empirical relation among evapotranspiration, potential evapotranspiration and precipitation observed across a variety of landscapes and biomes around the world. Using data from more than three hundred catchments and a simple water balance model, the Budyko curve is inverted to explore the ecohydrological controls of the soil water balance. Comparing the results across catchments reveals that aboveground transpiration efficiency and belowground rooting structure have adapted to the dryness index and the phase lag between peak seasonal radiation and precipitation. The vertical and/or lateral extent of the rooting zone exhibits a maximum in semi-arid catchments or when peak radiation and precipitation are out of phase. This demonstrates plant strategies in Mediterranean climates in order to cope with water stress: the deeper rooting structure buffers the phase difference between precipitation and radiation. Results from this study can be used to constrain land-surface parameterizations in ungauged basins or general circulation models.

Interdependence is when two countries are mutually dependent. It is a reciprocal relationship between individuals or groups. In layman’s terms, it’s when country “A” relies on country “B” and vice versa. An obvious example of interdependence is subsidies; financial assistance given by the government to a group. By providing another country with something that is in excess of and obtaining what is required in return helps the countries raise its economical state. This is crucially necessary for the sake of the economy. Another benefit that Canada can achieve through interdependence is that it can become more aware of deadly viruses that have been spreading globally and help prevent them. Interdependence between countries is also shown by the way they rely on each other for aid around the world. There is also a new idea out there regarding digital currency; this concept will definitely affect Canada’s interdependency with other countries. Last but not least, there is the formation of the UN that was established by 51 countries to preserve peace through international cooperation. 
Due to Canada’s mass, it has a large amount of exported agricultural products. Its agricultural exports are increasing at such an astonishing rate that it has been requested that agricultural subsidies be cut. Canada spends approximately $14 billion on agricultural subsidies and this results in us spending $2 billion less on international aid which is a very essential thing to do, (MacGregor A8). Produce is an essential item and no matter what the price is, people will buy, therefore these products have to be at a minimal cost. The government is giving farmers subsidies that results in cheaper products for the population (MacGregor A8). This will make us naturally less dependent on other countries and we won’t be helping their economy grow that much.
