Are there any risks that affect only the landlord, and not the renter, other than the possibility of losing ownership?
For example, if you rent a plot of land for farming, what risks does the owner of that land face that you do not?
The owner assumes the total risk for the property.
As a basic example, consider starting a lease vs buying a property in 2007. If you were a renter when the real estate market collapsed in 2008 you were stuck paying higher than the market rate (most likely) until your lease ended, at which point your rent probably dropped to market rate. No biggie.
If you bought property at the top of the market in 2007 for say $500k, and the value of that property dropped to $250k in 2008, you are now paying a $500k mortgage payment for a property worth half that amount. Rent used to cover your mortgage payment but now the market rate for rent in the same property has halved so now instead of breaking even every month on your property you have to pay $1,000 a month for someone else to live in your property just to not default on the mortgage. Odds of having to declare bankruptcy in this scenario are high.
Not at all. If you could not afford your property because of a loss of income, you are eligible for another mortgage after a short sale or foreclosure within a year. If you can't document a loss of income, its only 3 years to get another mortgage.
Temporary credit damage? Indeed, but not necessarily bankruptcy.
If you had $1 million in 2007, it would have been more profitable to invest it in Google than to buy a two houses in Mt View and rent them out. That is the risk the landlord is assuming. There are examples where you have a negative return as well.

In the US with civil forfeiture, the police can seize the property.

Real estate is not as easy to diversify as stocks and bonds, certain unexpected and uninsurable external shocks can have disastrous effects on the profitability of your investment. Things such as new rent control, property tax increase, termite damage, spiteful tenants, corrupt HoA, and sudden market volatility can all cause you to lose significant money.
I'm not getting the message behind the Churchill quote, landlords clearly have operating expenses to commit towards keeping a plot of land and shelter in useful or livable condition.
The renter generally pays a higher price per year than an owner but has greater options and less risk.
This is generally true of renting vs buying. If you go to distant city for a one-week vacation, you are likely to rent accommodations and a car rather than buy them. At the end of the week you can just walk away, whereas the owner must concern himself with generating an income with his property.
