from Lee County in Southwest Florida over 1988-2008. The results suggest that food risks slow down farmland
conversion while locational attributes, proxies for farming proftability, and regional economic indicators have
expected signs and magnitudes. Spatial model specifcation indicates positive contagion externalities in land
conversion. These fndings may be helpful in land use policy design.
1. Introduction
Over the past few decades, agricultural land has undergone ex-
tensive conversion into residential and commercial uses that are more
vulnerable to natural disasters. Coastal regions, in particular, have seen
many inundations whose impacts were aggravated by the intense ur-
banization of food-prone areas, which led to loss of human life and
propertydamages(Wagneretal.,2009).Empiricalworkhasshownthat
net returns to alternative land uses are the major driver of land use
change (Irwin and Bockstael, 2002, 2007; Bell and Bockstael, 2000).In
a coastal area, however, land use change is also afected by the dif-
ferences in expected losses from natural disasters (hazards) in diferent
land uses (Bin and Kruse, 2006). This paper evaluates the impact of
both rent capitalization and potential losses from natural disasters on
land conversion dynamics in an urbanized coastal area in Florida using
interval censored duration analysis.
Much of the existing work in natural sciences has focused on the
relationshipsbetweennaturalriskandlandusechange.Hydrologicand
geographic studies emphasize the impact of natural disasters on land
use change. One concern identifed in this literature is that land cover
change afects not only the degree of infltration but also runof from
precipitation (Parrott et al., 2009). According to Mustard et al. (2012),
land surface performs a crucial function in the water cycle as it redis-
tributes precipitation into evaporation, runof, or soil moisture storage.
Tollan (2002) and Brath et al. (2006) fnd that food frequency can be
signifcantly reduced by modifyingthelandscapeorthroughlandcover
change. Similarly, Du et al. (2012), in analyzing land use in a coastal
areainChina,suggestthatlandusechangesignifcantlyincreasesdirect
runof in the long term, which is closely correlated with food events.
Another concern is the impact of urbanization on the discharge process
that increases the risk of fooding due to increased peak discharge and
volume (Nirupama and Simonovic, 2007; Suriya and Mudgal, 2012).
Schilling et al. (2014) also argue that undeveloped land can efciently
reduce food risks.
The economic models of land use change focus on explaining the
causal relationships between the returns to land in diferent uses and
land use change. The focus is on individual owners’ land use decisions
governed either by maximization of expected returns or utility derived
from the land (Irwin and Bockstael, 2002; Irwin et al., 2003; Irwin and
Bockstael, 2007). Landowners’ decisions on whether and when to
convert their land are based on maximization of the net present value
(NPV) of returns from land and the expected exposure to natural ha-
zards in diferent land uses. The decision to convert emphasizes in-
dividual choice in a static setting, while the timing of conversion in-
corporates future (expected) changes in demand, supply, and
productivity, as well as the option value of not converting (Bell et al.,
2006). The theory has been tested in empirical studies that identify
land’s locational attributes and soil quality as fundamental elements in
the agricultural land conversion decisions (Miller and Plantinga, 1999;
Lubowski et al., 2008), but the role of natural hazards remains less
