Fund highlights

* "While the world's use of natural resources may not always rise
   smoothly and steadily, demand for these commodities is growing as
   countries around the globe modernize their economies. The portfolio's wide
   diversification among industries, geographic markets, and natural resource
   sectors seeks to produce solid returns while dampening the effects of a
   downturn in any one market or region."

Dear Shareholder:

It is difficult to imagine any thread in our world's economic weave that does
not in some fashion involve natural resources. Companies that provide the
fuels to power our factories and supply the materials to construct and
maintain our roads and buildings play prominently in the business of the
global village.

From this worldwide array of companies, Fund Manager Jeanne Mockard constantly
seeks out the most efficient and productive to include in the portfolio of
Putnam Global Natural Resources Fund. She is backed by an equity research
capability that ranks among the mutual fund industry's best.

The effectiveness of an investment focus on global natural resources over both
the fiscal year ended August 31, 1997, and longer periods is demonstrated in
the performance tables that follow Jeanne's management report. On the
following pages, she discusses the market and economic environment that
prevailed during fiscal 1997 and looks at prospects for the fiscal year just
begun.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
October 15, 1997



Report from the Fund Manager
Jeanne L. Mockard

As developing nations around the world continue to industrialize their
economies and modernize their physical infrastructures, the demand for natural
resources continues to grow. The building of bridges and roads, the
introduction of modern telecommunications, and the construction of housing and
commercial structures -- all of these changes create a need for the energy,
chemicals, metals, minerals, and other natural resources that underlie the
business of the companies in which this fund invests.

It is no surprise, then, that during the 12 months ended August 31, 1997,
Putnam Global Natural Resources Fund's class A shares rose by 31.39% at net
asset value and 23.84% at public offering price. For results over longer
periods and performance of class B and class M shares, please refer to pages 9
and 10.

* DIVERSIFICATION AND GLOBAL EMPHASIS PROVIDE PROTECTION AND STRONG RETURNS

Throughout the fiscal year, the fund's portfolio remained concentrated in
large multinational company stocks from a wide spectrum of industries. Many
are familiar, household names including Exxon, du Pont, Dow Chemical, and
Mobil, while others such as Freeport-McMoRan Copper & Gold Co. and
Schlumberger Ltd. are lesser known to consumers yet produce cutting-edge
products and hold industry leadership positions. As economic reforms and the
adoption of free-market policies continued throughout Asia, Latin America, and
the Pacific Rim, these multinational holdings provided strong returns during
the period.

Your fund's large-company, multinational stock holdings offer important
advantages. As the name implies, these companies sell their goods and services
in markets around the world so that a short-term problem in one country or
region is unlikely to affect their overall performance. In fact, a downturn in
one local economy may even benefit a multinational company by reducing some of
its production costs without affecting profits, which accrue in many different
countries. This is exactly what happened in Asia during your fund's fiscal
year as downturns in some local economies lowered costs for many petroleum
companies. At the same time, oil -- which is priced in dollars and is their
main commodity -- remained in demand and continued to bring in large profits.
In addition, many multinational companies have undertaken strict cost-cutting
measures in recent years, leaving them more profitable than ever, even in
today's environment of lower price margins.

* OIL POSITION BENEFITS FROM PRICE CHANGES, LARGE-CAP FOCUS, AND TREND TOWARD
  PRIVATIZATION

Oil stocks remained the fund's largest sector weighting throughout the period.
Last fall, when oil prices peaked, we shifted some of the fund's assets away
from stocks we believed had become fully valued. Some months later, Iraq was
allowed to resume oil production, eliminating a wild card that had been
creating a great deal of market uncertainty and price volatility. By March,
oil prices had retreated to their normal trading range -- $18 to $22 per
barrel -- as did oil stock prices. We capitalized on these lower prices to
increase oil holdings to an overweight position in anticipation of continued
solid returns in the months ahead.

[GRAPHIC OMITTED: horizontal bar chart TOP INDUSTRY SECTORS] 

TOP INDUSTRY SECTORS*

Oil and gas               35.2%

Chemicals                 14.0%

Oil services               9.9%

Metals and mining          7.9%

Paper and forest products  6.3%

Footnote reads:
*Based on net assets as of 8/31/97. Holdings will vary over time.

The fund's focus on large-capitalization oil company stocks also contributed
to strong performance in fiscal 1997. Last year, heavy exploration and
drilling demand and a shortage of companies equipped to provide these services
led to outperformance by small oil service company stocks. During 1997,
however, the market took back these gains and the large-company stocks favored
by this fund soon began to outperform once again.

In Europe, the trend toward privatizing formerly state-run oil companies also
created some unique investment opportunities during the period. The stocks of
these companies are selling at extremely attractive valuations relative to the
stocks of major oil companies such as British Petroleum and Exxon. After
meeting with the managements of several of these companies, we decided to add
ENI SPA of Italy, Elf Aquitaine of France, and YPF of Argentina to the
portfolio. We believe these companies are now well prepared to compete
successfully in the growing world market and have excellent performance
potential going forward. While these holdings, along with others discussed in
this report, were viewed favorably at the end of the fiscal period, all
portfolio holdings are subject to review and adjustment in accordance with the
fund's investment strategy and may vary in the future.

* CHEMICAL STOCKS CONTINUE OUTPERFORMANCE; PAPER HOLDINGS INCREASED

Chemical stocks were another of the portfolio's major sector allocations, at
14% of net assets. Once again these holdings were top performers, benefiting
from solid fundamentals and individual company strengths. Two holdings in
particular, du Pont and Dow Chemical Co., remain performance leaders. In both
cases, aggressive cost cutting has made the companies highly productive and
profitable, while innovative new products continue to sustain their
competitive edge in the market.

One of the major benefits of your fund's multisector strategy is the
portfolio's ability to shift into and out of different natural resource
industries as opportunities arise. During the recent period, we took advantage
of this flexibility to increase holdings in the paper and forest products
sector, giving the portfolio an overweight position in these areas. Prices on
paper, pulp, and packaging products began to firm during the latter half of
the fiscal year just as steady demand reduced inventories.

Portfolio holdings will vary over time

* IN METALS AND MINING, STRENGTH AMID WEAKNESS

The fund maintained approximately 8% of its assets in metals and mining stocks
over the period, focusing on companies with strong fundamentals and
diversified operations. In fact, although gold prices remained low throughout
the fiscal year, Freeport-McMoRan Copper & Gold Co., one of the fund's
holdings in this sector, delivered extremely strong relative returns. This
Louisiana-based company is conservatively managed and holds a world leadership
position in the exploration and recovery of copper, gold, and silver. Thus,
although gold prices moved lower over the period, Freeport-McMoRan's stock
rose in value as its diversified operations yielded profitable results.

* FAVORABLE ECONOMIC TRENDS CREATE OPTIMISTIC OUTLOOK

As we begin a new fiscal year, most global economies are in good shape,
although the Asian markets bear close watching to determine whether current
difficulties will be short lived or deepen with time. We will continue to
monitor natural resources industries around the world, seeking to keep the
portfolio well diversified while also taking advantage of the stocks of large
multinational companies.

The views expressed here are exclusively those of Putnam Management. They are
not meant as investment advice. Although the described holdings were viewed
favorably as of 8/31/97, there is no guarantee the fund will continue to hold
these securities in the future. Funds investing in a single sector may be
subject to more volatility than funds investing in a diverse group of sectors.
International investing involves certain risks, including those related to
economic instability, unfavorable political developments, and currency
fluctuations, not present with domestic investments.

Returns for class A and class M shares reflect the current maximum initial
sales charges of 5.75% for class A shares and 3.50% for class M shares.
One-, five-, and ten-year (when available) and life-of-fund returns for
class B shares reflect the applicable contingent deferred sales charge
(CDSC), which is 5% in the first year, declines each year to 1% in the
sixth year, and is eliminated thereafter. Returns shown for class B and
class M shares for periods prior to their inception are derived from the
historical performance of class A shares, adjusted to reflect both the
initial sales charge or CDSC, if any, currently applicable to each class
and, in the case of class B and class M shares, the higher operating costs
applicable to such shares. All returns assume reinvestment of
distributions at NAV and represent past performance; they do not guarantee
future results. Investment return and principal value will fluctuate so
that an investor's shares when redeemed may be worth more or less than
their original cost.

Performance data represent past results, do not reflect future

section for performance calculation method.

TERMS AND DEFINITIONS

Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested all
distributions in the fund.

Class A shares are generally subject to an initial sales charge.

Class B shares may be subject to a sales charge upon redemption.

Class M shares have a lower initial sales and a higher 12b-1 fee than
class A shares and no sales charge on redemption.

Net asset value (NAV) is the value of all your fund's assets, minus any
liabilities, divided by the number of outstanding shares, not including
any initial or contingent deferred sales charge.

Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the maximum 5.75% sales charge for class A
shares and 3.50% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time of
the redemption of class B shares and assumes redemption at the end of the
period. Your fund's CDSC declines from a 5% maximum during the first year
to 1% during the sixth year. After the sixth year, the CDSC no longer
applies.

Report of independent accountants

To the Trustees and Shareholders of
Putnam Global Natural Resources Fund

In our opinion, the accompanying statement of assets and liabilities,
including the portfolio of investments owned, and the related statements of
operations and of changes in net assets and the financial highlights present
fairly, in all material respects, the financial position of Putnam Global
Natural Resources Fund (the "fund") at August 31, 1997, and the results of its
operations, the changes in its net assets and the financial highlights for the
periods indicated, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the fund's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of investments owned at August 31, 1997 by correspondence with
the custodian and the application of alternative auditing procedures where
investments purchased were not yet received by the custodian, provide a
reasonable basis for the opinion expressed above.

Notes to financial statements
August 31, 1997

Note 1
Significant accounting policies

Putnam Global Natural Resources Fund ("the fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-ended
management investment company. The fund continues to seek capital appreciation
by investing primarily in the common stocks of companies in the energy and
natural resource industries, but may also invest a portion of its assets in
other industries and in fixed-income securities.

The fund offers class A, class B and class M shares. Class A shares are sold
with a maximum front-end sales charge of 5.75%. Class B shares, which convert
to class A shares after approximately eight years, do not pay a front-end
sales charge, but pay a higher ongoing distribution fee than class A shares,
and are subject to a contingent deferred sales charge, if those shares are
redeemed within six years of purchase. Class M shares are sold with a maximum
front-end sales charge of 3.50% and pay an ongoing distribution fee that is
lower than class B shares and higher than class A shares.

Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears expenses unique to that class (including
the distribution fees applicable to such class). Each class votes as a class
only with respect to its own distribution plan or other matters on which a
class vote is required by law or determined by the Trustees. Shares of each
class would receive their pro-rata share of the net assets of the fund, if the
fund were liquidated. In addition, the Trustees declare separate dividends on
each class of shares.

The following is a summary of significant accounting policies consistently
followed by the fund in the preparation of its financial statements. The
preparation of financial statements is in conformity with generally accepted
accounting principles and requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities. Actual
results could differ from those estimates.

A) Security valuation Investments for which market quotations are readily
available are stated at market value, which is determined using the last
reported sale price, or, if no sales are reported -- as in the case of some
securities traded over-the-counter -- the last reported bid price. Securities
quoted in foreign currencies are translated into U.S. dollars at the current
exchange rate. Market quotations are not considered to be readily available
for some convertible securities; such investments are stated at fair value on
the basis of valuations furnished by a pricing service approved by the
Trustees, which determines valuations for normal, institutional-size trading
units of such securities using methods based on market transactions for
comparable securities and various relationships between securities which are
generally recognized by institutional traders. Short-term investments having
remaining maturities of 60 days or less are stated at amortized cost, which
approximates market, and other investments are stated at fair value following
procedures approved by the Trustees.

B) Joint trading account Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the fund may transfer uninvested cash
balances into a joint trading account along with the cash of other registered
investment companies and certain other accounts managed by Putnam Investment
Management, Inc. ("Putnam Management"), the fund's Manager, a wholly-owned
subsidiary of Putnam Investments, Inc.. These balances may be invested in one
or more repurchase agreements and/or short-term money market instruments.

C) Repurchase agreements The fund, or any joint trading account, through its
custodian, receives delivery of the underlying securities, the market value of
which at the time of purchase is required to be in an amount at least equal to
the resale price, including accrued interest. Putnam Management is responsible
for determining that the value of these underlying securities is at all times
at least equal to the resale price, including accrued interest.

D) Security transactions and related investment income Security transactions
are accounted for on the trade date (date the order to buy or sell is
executed). Interest income is recorded on the accrual basis. Dividend income
is recorded on the ex-dividend date except that certain dividends from foreign
securities are recorded as soon as the fund is informed of the ex-dividend
date.

E) Foreign currency translation The accounting records of the fund are
maintained in U.S. dollars. The market value of foreign securities, currency
holdings, other assets and liabilities are recorded in the books and records
of the fund after translation to U.S. dollars based on the exchange rates on
that day. The cost of each security is determined using historical exchange
rates. Income and withholding taxes are translated at prevailing exchange
rates when accrued or incurred. The fund does not isolate that portion of
realized or unrealized gains or losses resulting from changes in the foreign
exchange rate on investments from fluctuations arising from changes in the
market prices of the securities. Such fluctuations are included with the net
realized and unrealized gain or loss on investments. Net realized gains and
losses on foreign currency transactions represent net exchange gains or losses
on closed forward currency contracts, disposition of foreign currencies and
the difference between the amount of investment income and foreign withholding
taxes recorded on the fund's books and the U.S. dollar equivalent amounts
actually received or paid. Net unrealized appreciation and depreciation of
assets and liabilities in foreign currencies arise from changes in the value
of open forward currency contracts and assets and liabilities other than
investments at the period end, resulting from changes in the exchange rate.

F) Forward currency contracts The fund may engage in forward currency
contracts, which are agreements between two parties to buy and sell currencies
at a set price on a future date, to protect against a decline in value
relative to the U.S. dollar of the currencies in which its portfolio
securities are denominated or quoted (or an increase in the value of a
currency in which securities a fund intends to buy are denominated, when a
fund holds cash reserves and short-term investments). The U.S. dollar value of
forward currency contracts is determined using forward currency exchange rates
supplied by a quotation service. The market value of the contract will
fluctuate with changes in currency exchange rates. The contract is "marked to
market" daily and the change in market value is recorded as an unrealized gain
or loss. When the contract is closed, the fund records a realized gain or loss
equal to the difference between the value of the contract at the time it was
opened and the value at the time it was closed. The fund could be exposed to
risk if the value of the currency changes unfavorably, if the counterparties
to the contracts are unable to meet the terms of their contracts or if the
fund is unable to enter into a closing position.

G) Federal taxes It is the policy of the fund to distribute all of its taxable
income within the prescribed time and otherwise comply with the provisions of
the Internal Revenue Code applicable to regulated investment companies. It is
also the intention of the fund to distribute an amount sufficient to avoid
imposition of any excise tax under Section 4982 of the Internal Revenue Code
of 1986, as amended. Therefore, no provision has been made for federal
taxes on income, capital gains or unrealized appreciation on securities held
nor for excise tax on income and capital gains.

H) Distributions to shareholders Distributions to shareholders from net
investment income are recorded by the fund on the ex-dividend date. Capital
gain distributions, if any, are recorded on the ex-dividend date and paid at
least annually. The amount and character of income and gains to be distributed
are determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. These differences include treatment
of losses on wash sale transactions, unrealized losses on forward foreign
currency contracts, post October foreign loss deferrals and non-taxable
dividends. Reclassifications are made to the fund's capital accounts to
reflect income and gains available for distribution (or available capital loss
carryovers) under income tax regulations. For the year ended August 31, 1997,
the fund reclassified $60,002 to decrease paid-in-capital, with an increase to
accumulated net realized gain on investments of $60,002. The calculation of
net investment income per share in the financial highlights table excludes
these adjustments.

Note 2
Management fee, administrative services and other transactions

Compensation of Putnam Management, for management and investment advisory
services is paid quarterly based on the average net assets of the fund. Such
fee is based on the following annual rates: 0.70% of the first $500 million of
average net assets, 0.60% of the next $500 million, 0.55% of the next $500
million, 0.50% of the next $5 billion, 0.475% of the next $5 billion, 0.455%
of the next $5 billion, 0.44% of the next $5 billion, 0.43% thereafter. Prior
to December 20, 1996, any amount over $1.5 billion was based on 0.50%.

The fund reimburses Putnam Management for the compensation and related
expenses of certain officers of the fund and their staff who provide
administrative services to the fund. The aggregate amount of all such
reimbursements is determined annually by the Trustees.

Custodial functions for the fund's assets are provided by Putnam Fiduciary
Trust Company (PFTC), a wholly-owned subsidiary of Putnam Investments, Inc.
Investor servicing agent functions are provided by Putnam Investor Services, a
division of PFTC.

For the year ended August 31, 1997, fund expenses were reduced by $137,087
under expense offset arrangements with PFTC and brokerage service
arrangements. Investor servicing and custodian fees reported in the Statement
of operations exclude these credits. The fund could have invested a portion of
the assets utilized in connection with the expense offset arrangements in an
income producing asset if it had not entered into such arrangements.

Trustees of the fund receive an annual Trustees fee of $870 and an additional
fee for each Trustee's meeting attended. Trustees who are not interested
persons of Putnam Management and who serve on committees of the Trustees
receive additional fees for attendance at certain committee meetings.

The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan") which
allows the Trustees to defer the receipt of all or a portion of Trustees Fees
payable on or after July 1, 1995. The deferred fees remain in the fund and are
invested in certain Putnam funds until distribution in accordance with the
Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension plan
(the "Pension Plan") covering all Trustees of the fund who have served as
Trustee for at least five years. Benefits under the Pension Plan are equal to
50% of the Trustee's average total retainer and meeting fees for the three
years preceding retirement. Pension expense for the fund is included in
Compensation of trustees in the Statement of operations. Accrued pension
liability is included in Payable for compensation of Trustees in the Statement
of assets and liabilities.

The fund has adopted distribution plans (the "Plans") with respect to its
class A, class B and class M shares pursuant to Rule 12b-1 under the
Investment Company Act of 1940. The purpose of the Plans is to compensate
Putnam Mutual Funds Corp., a wholly-owned subsidiary of Putnam Investments
Inc., for services provided and expenses incurred by it in distributing shares
of the fund. The Plans provide for payments by the fund to Putnam Mutual Funds
Corp. at an annual rate up to 0.35%, 1.00% and 1.00% of the average net assets
attributable to class A, class B and class M shares, respectively. The
Trustees have approved payment by the fund at an annual rate of 0.25%, 1.00%
and 0.75% of the average net assets attributable to class A, class B and class
M shares respectively.

For the year ended August 31, 1997, Putnam Mutual Funds Corp., acting as
underwriter received net commissions of $153,986 and $10,359 from the sale of
class A and class M shares, respectively and $166,547 in contingent deferred
sales charges from redemptions of class B shares. A deferred sales charge of
up to 1% is assessed on certain redemptions of class A shares. For the year
ended August 31, 1997, Putnam Mutual Funds Corp., acting as underwriter
received $4,424 on class A redemptions.

Note 3
Purchase and sales of securities

During the year ended August 31, 1997, purchases and sales of investment
securities other than short-term investments aggregated $195,107,251 and
$125,659,508, respectively. There were no purchases and sales of U.S.
government obligations. In determining the net gain or loss on securities
sold, the cost of securities has been determined on the identified cost basis.

Note 4
