Keeping living roots in the ground, using cover crops to prevent erosion, and rotating shallow and deep rooting crops can increase soil health. 2. Water Climate change is increasing the frequency and severity of drought and flooding incidents. Improving floodwater defences and drainage on farms, ...
Why does groundwater have more dissolved substances than surface water? Why is groundwater considered to be a very clean source of water? Why is coastal erosion from cyclones a problem? Why is ocean salinity increasing? Why is groundwater important to the environment?
What is the role of agrochemicals in increasing food production? How does deforestation lead to soil erosion and soil degradation? Can not using fertilizer cause soil degradation? Why are nutrients from fertilizer harmful to aquatic ecosystems?
food output by 2050. It IS more likely, when use of pesticides, fertilizers, genetically modified organisms will be performing at constantly increasing rate, rather than applying principles of sustainable, organic, permaculture agriculture. Such assumptions can be proven with the following: most develop...
The increasing integration of the world, in terms of financial, trade, aid and other economic flows, as well as health, educational, scientific and other opportunities requires an increas- ingly sophisticated policy capability. So too does the management of the risks Why Do Some Countries Develop...
downstream enterprises. Carbon tax will increase the cost of energy consumption. Intuitively, carbon tax with full industry coverage may have the same effect with resource tax with full primary energy coverage, but the effects are totally different, as depicted in Fig.6. Why does this happen?
Just 50 years ago, no one knew why the Earth has mountains. Now we do. This is the story of how we figured it out - and how we keep learning.
Primary succession takes longer than secondary successionbecause soil needs to be created. Soil is already present in secondary succession. ... lichens and erosion help break down the rock to form new soil. Does succession happen in an urban environment?
does end badly. And all empires end the same way, with the assumption that nothing will happen. The currency’s acceptance as a reserve does come to an end. The persistent erosion of purchasing power and declining confidence in the legally imposed “lowest risk asset” are some of the red...
Why does the salinity of seawater remain constant? Why does ground-level ozone usually occur near the ocean? Why doesnt refraction happen at a curved surface? Why is the bottom layer of the ocean the coldest? Why does an increase in frequency not increase the velocity of wave? What causes ...
