Do I need to buy a separate map?

A good wall map earns its place more than an extra book does. The habit of locating what you read cuts the memorising work substantially.

Must I memorise a list of past disasters?

The framework matters more than the list. Questions tend to be about process, agencies and warning signals rather than a roll of past events.

Does this overlap with Bangladesh Affairs?

It does overlap, particularly on rivers and natural resources. Use that: reading them together advances both papers at once.

Geography is learned by looking as much as by reading. A name on a page is only a name; on a map it becomes a position, and positions stay in the memory far longer.

What the section covers

Area	Core content
Landforms	Hills, plains and floodplain divisions
River systems	Major rivers, sources and confluences
Climate	The seasonal cycle and monsoon
Natural resources	Gas fields, minerals and forests
Pollution	Types, causes and effects
Disaster management	Preparedness, response, rehabilitation

Reading it off the map

Put a large map on the wall and find on it whatever you are reading. When you meet a river, trace with a finger where it rises and where it joins; when you meet a district, look at its neighbours. This single habit halves the memorising.

The paper frequently asks positional questions — which district holds what, which river a place sits on. Reading with a map means you never have to memorise those separately.

What matters in the disaster section

Disaster questions are usually about process — what happens at which stage, which agency carries which responsibility, what the warning signals mean. So it is the management framework, not a list of past events, that you need to hold.

Separate the three stages: preparedness, response, rehabilitation.
Cyclone and flood warning systems are different — do not conflate them.
Keep a one-page map of which agency does what.

How to move through the environment part

In the environment part it is the link between type, cause and effect that carries the marks. Writing cause and consequence side by side for each kind of pollution lets you answer from either direction, since the paper asks sometimes for one and sometimes for the other.

Forest cover shares, gas reserves and pollution statistics are revised regularly — use them only after checking the relevant ministry’s latest report.
