Hello children today in geography we  shall do chapter number eight regional Development this is one of the most beautiful lessons of geography which i have come across so let us have fun with chapter number 8 well before we begin with this lesson let’s go through the index the first thing we shall understand in the lesson is the concept of development Second what is regional development third what does regional imbalance forth what is human development index and last but not the least is what is the regional development in our very own state of Maharashtra  well let us  now understand the concept of development you will see 3 words across the screen change growth development My dear children do these words mean the same or are they different well let us find out with an example one day I sowed  a seed and after sowing the seed I saw to it that i watered and nurtured it and soon enough what happened after a few months the small little seed had transformed into a beautiful tree see  and this tree consisted of delicious apples well my dear children the seed becoming a tree is a change what is a change. change means to become different change is a natural process change takes place with plants it also takes place with animals change takes place with human beings with regions but you should always remember that whenever change takes place it has two directions the first direction is a progressive change the second direction is a non progressive change progressive change is a positive change non-progressive change is a negative change let us understand this better the change of a seed To a tree  is a progressive of change a positive change right and the non germination of the seed is a non progressive change look at the seed crying because it knows it has gone in the part of non progressive change so we have to take utmost care while changes occurring progressive change always leads to a desired growth then what is growth . growth is a change in the direction from lesser to more or from lower to higher my dear children earlier you saw the plant had less roots les stems less leaves but now the tree is definitely having more roots more stems more leaves right that’s definitely a progressive growth  when the tree is growing its different components like the roots and stems the branches and the leaves flowers and the Fruits all grow in proper proportion this is known as an all-around growth or a desired growth let us now understand what is a non progressive change a non progressive change leads to an undesired growth for example the growth of weeds is an undesired growth because the weeds will eventually destroy the tree right now whenever you find across you poverty or you come across disease waste and crime in cities definitely what you are seeing is an undesired growth in the cities these are all negative changes taking place around you which is really very bad right the desired growth leads to development and a non desired growth leads to no Development now let me make things more clear about change growth and development always remember that at first what takes place is always change and when there is a progressive of change it leads to growth and when the growth is in the desired direction it leads to development change and growth and narrow concepts well development is a broad concept change is a natural process development is a planned to process it takes a lot of efforts to develop your region yourself as a human being even the plant which you watered then nurtured so my dear children there is a formula for development. development is equal to progressive change plus desired growth  that’s the end of our module the concept of development in the next module we shall understand what is regional development
