Through a basic income: Many already receive a basic income which can be spent on individual development. For instance, old-age pensions and compensation for those unable to work are often financed from income taxes. The US State of Alaska provides all residents with a basic income funded by oil revenue: all are part-owners of the rich oil reserves. Brazil contributes funds for the development of the poorest provided that they send their children to school and/or have them inoculated. 

Issuing tradable permits to citizens world-wide as a way to combat both Climate Change and Poverty. This method provides each person with a quota of energy for their use. This is like a basic income. Those not needing their full quota can sell a part to those seeking to use more. This is a way for countries to more easily meet the targets set by Kyoto or other international agreements.

Taxation: Universities, research institutes, and interested citizens have developed diverse creative methods of financing individual development by reshuffling existing tax systems; some discourage undesirable behaviours by replacing or supplementing existing ones with “polluter pays”, “consumption” or “currency exchange” (Tobin) taxes. Others suggest one equal basic income for all, so that the costs of administrating a country’s complex tax system can be greatly decreased and the money saved through a skeletal bureacracy can be used to help to finance the basic income.

Microfinancing: The Grameen Bank which provides small loans to microenterpreneurs, including beggars, has won Muhammad Yunis the Nobel Peace Prize; Trickle Up provides micro-grants to the very poorest. The micro financing is distributed via local NGOs.
 
Barter. The Local Exchange Trading System (LETSystem) is in use in communities world-wide. Time sharing is a form of barter used also in New York, whereby people exchange services: e.g one hour of gardening for one hour of tutoring or psychological counseling. In each case, there is a central form of accounting whereby each participant is listed both with regard to products and services offered and needs, so that whoever participates in a barter, pays to or receives points (called variously, Green Dollars, Stars, Noppes, etc.) from the system as a whole. There are plans to further develop the LETSystem into a global system.

Alternative currencies have been suggested to deal with a range of problems at the local level. Here is an example which has drawn comments by a number of Leaders (Part 3):

A Supplementary Global Economy: The late Dutchman Pieter Kooistra with the endorsement of Nobel Prize Winner Jan Tinbergen outlines how a global barter system can be used to finance a Supplementary Global Economy which would leave all existing economies in tact.
This would be financed by a hard virtual (or giro) currency with as collateral the extra marketable goods and services which emerge when the unmet needs for goods and services globally are linked with unmet need for additional markets. The extra currency can be divided equally among all to provide them with a basic income
This Supplementary Global Economy would address both material and spiritual poverty as well as a gamut of associated challenges by exclusively permitting trade in sustainable goods and services (as agreed upon with the input of citizens world-wide).
