More efficient use of agricultural land can boost crop yields and meet growing global demand for food. Smallholders have a vital role to play, both because they produce much of the world's food and because they represent a large share of the world's poor and food insecure.
The three types of pf plate boundaries are spreading zones, transform faults and subduction zones. Most earthquakes occur along the boundaries of plate tectonics due to the effects of the earth's mantle layer that acts as a recycling agent and recycles 99% of the earth's surface layers from above.
Various tectonic forces and process act son these slabs and rocks from above and hence through the activities of erosion and denudation of the rocky masses these plates collide with each other as the earth is it's self not static its dynamic and moves continuously on a regular basis and hence changes take place on the surface of earth.
Thus it can be seen that the earthquakes and volcanic events occur at the plate boundaries and hence produce or are responsible for the various activities.
People generally move in climates where it's warm, but not too hot. That way they can hunt, raise livestock, and grow food for everyone. Also, it's just a nice climate in general to stay in. Hope this helped :)
