This would imperatively require a two pronged strategy:
1. Effective means to get relocation done for the existing slum dwellers.
2. Prevent other chunk of population to add to the chunk of existing slums or create new slums (in same cities or other cities).
Tackling either of the above two would be like trying to fill a leaky bucket with water. The resources/efforts put in will not yield desired results since on one hand you try to fill & on the other hand your efforts get ineffected by the leakage. Result=> Ineffective Solution. Thus both the above require to be addressed.
Now before trying to tackle the above two, it is desired to understand the root cause of the problem i.e a need to figure out the major reasons for the slums to come up & what prevents the existing slums to be erradicated?
I provide below a broad framework of this approach:
Reason for slums coming up:
Reason 1. The Pull factor: The people from rural ares migrating in search of new & greener pastures sinectheir traditional source of livelihood (primarily agriculture) marred by various recent developments such as weather, decreasing demand for their produce, ineffective support from government/others, high cost of loans to start a new source of livelihood etc.
Reason 2. A chunk of unskilled population trying to continue their battle for a better living seeing the well to do city population.
& So on list all the major plausible reasons.
Thereafter list all the plausible measures as an answer to the above reasons:
Measure 1: Prevention of villagers migrating to villages out of compulsion by providing better infrastruture & source of livelihood to them in their villages itselg eg. technological help, colective grouping for better yield on their produce, elimination/reduction of intermediaries to get them more return on their produce, low cost loans & guidance mechanism to start up a new source/venture etc. The essence is to make them happy in their native place rather than leaving them to migrate to cities out of compulsion & add to the slums.
Measure 2: Relocating the existing slum dwellers to a new place/their native place. With an effective communication & implementation of measure 1 quite a few may be motivated to relocate to their native places as quite a few of the slum dwellers would have their origins in rural areas.
The others who do not migrate are to be relocated to new areas with better living conditions. A proper open system of communication is also must for the efforts to succeed in the long run. The slum dwellers should not only have an option of a better home with basic facilities such as water, light, road etc. but also a source of livelihood near the new place. This kind of solution need to be understood for acceptance & being effective & hence the need for an open communication & harbouring of trust. For this a team may be formed from the existing slum dwellers in each of the sulms & an effort made to make this team realize the benefits of relocation. This team should then support in communicating these to others in the slums. The choice of the right candidates in this team would be mandatory for success of any initiative. Those youths that are open to communication, motivated for the upliftment of their peers & are trusted by their peers are to be roped in.
& So on.
