Article
Cover cropping is a sustainable strategy for increasing soil nutrients and organic matter, and improving overall soil health. This practice is heavily promoted for annual vegetable growers; however, there is less widespread acknowledgement for cover crops as a management strategy in perennial settings. Research is limited in this field, specificall...

Tomato (Solanum lycopersicum L.) is an important vegetable crop in Florida, a state located in the southeastern region of the United States. The state is the second largest producer of tomatoes in the country and contributes to almost 90% of the domestic winter tomato supplies. However, tomato farmers in Florida have come under increasing pressure...

Coastal ecosystems are at great risk from climate change and sea level rise, potentially resulting in loss of habitat and economic costs to society. This study aimed to investigate whether users' attitudes toward climate risks have any bearing on how they value ecosystem services and express the desire to mitigate risks. The study used psychometric...
Article
This study aims to examine whether individuals' attitudes toward the anthropogenic risks facing staghorn corals and coral reef ecosystems off the Southeast (SE) coast of Florida influence their valuation of coral reef ecosystem services and willingness to mitigate risks. We use preference data and psychometric measures characterizing the public's a...
Article
As global fisheries management shifts towards ecosystem-based management, responsible organizations and governments must also address the socio-economic impacts of this shift. This study evaluates potential impacts of such management shift with a case study of Pulley Ridge (PR), an ecologically rich area in the Gulf of Mexico, on fishermen and econ...

We present a new Priority Rated Optimization Model (PROM) for multi-sector water resource assessment, allocation and management. PROM utilizes flow duration curves (FDC), demand-to-supply ratio (DSR) and utility indices (UI) to evaluate and optimize priority based multi-sector water allocation. DSR links demand volume and priority with correspondin...

Crop insurance claims can serve as a metric of the climate-related vulnerability of agriculture. As the expected frequency and intensity of flood and extreme precipitation increases over time, the amount of indemnities paid upon losses due to these events is also expected to increase. This study develops a game-theoretic model of agricultural polic...

Mangrove ecosystems are among the most important and productive coastal ecosystems globally. Due to their high productivity and rapid carbon cycling, these ecosystems are important modulators of carbon fluxes from the land to the ocean and between water and atmosphere. As a consequence, they may play a crucial role for the global carbon cycle and c...

Article
For decades, the increase of nutrient enrichment has threatened the ecological integrity and economic sustainability of many rivers, lakes, and coastal waters, including Lake Okeechobee, the second largest freshwater lake in the contiguous United States. Water quality trading programs have been an area of active development to both, reduce nutrient...
Article
Old growth mangroves in existing protected areas store more carbon than restored forests or plantations. Carbon storage in such forests has economic value independent of additionality, offering opportunities for policy makers to ensure their maintenance, and inclusion in climate change mitigation strategies. Mangrove forests of the Everglades Natio...

This chapter develops a concise, but comprehensive, plan for designing and developing a payment for watershed services (PWSs) mechanism in the Mara River basin (MRB), Kenya. It will describe the current water situation in the Mara and future trends. It will make the “case” for improved land management practices and more efficient water use in the h...
Article
Water quality and economic models were linked to assess the economic and environmental benefits of implementing a phosphorus credit trading program in an agricultural sub-basin of Lake Okeechobee watershed, Florida, United States. The water quality model determined the effects of rainfall, land use type, and agricultural management practices on the...
Article
The Mara River in East Africa is currently experiencing poor water quality and increased fluctuations in seasonal flow. Improved water quality will require upstream farmers and foresters to adopt Best Management Practices (BMPs), which might cost them considerably. This study proposes a Payment for Watershed Services (PWS) mechanism. This is a mark...

About a quarter of Chinese wild orchid species are used in traditional medicine or as health food supplements. The market demand for some species, such as those in the epiphytic genus Dendrobium, has diminished many wild populations to local extinction or dangerously small numbers. Conservation of these heavily exploited orchids currently relies on...
Article
A simple model was developed to assess space–time relationships of water resource availability and demand in data limited watersheds. The model used a defined index method to evaluate water resource status with respect to anticipated demands. Input data requirements and data processing steps and strategies were discussed. The model takes outputs fr...

The migratory nature of nuisance wildlife populations creates a special management problem by imposing a negative diffusion externality on landowners undertaking control efforts. This paper reviews three cost-minimizing wildlife-control models, each internalizing the diffusion externality under different management scenarios, namely, unilateral man...
Article
National agricultural policies intended to stabilize farm price and income may have different impacts on different agricultural sector of a state or a region. A policy which influences a region's agriculture also may affect the general economy of that region, depending on the degree to which agriculture is linked to the general economy. This study...

Agricultural chemicals that are derived from fossil-fuels are the major energy intensive inputs in agriculture. Growing scarcity of the world`s fossil resources stimulated research and development of energy-efficient technology for manufacturing these chemicals in the last decade. The purpose of this study is to revisit the energy requirements of m...
Article
This paper discusses the implications that The European Economic Community's recent Wild Fur Regulation (WFR) might have on the U.S. wildlife damage control program. Beginning Jan. 1, 1995, the regulation will ban fur imports originating from countries which fail to (1) stop foothold trapping, and (2) adopt international humane trapping standards....
Article
The US Castor canadensis population has caused severe damage to valuable timberland through dam-building and flooding of bottomland forest. Since beaver populations are mobile, beaver extermination in controlled parcels results in beaver immigration from neighbouring less controlled parcels. This study develops a bioeconomic model that incorporates...
Article
A bioeconomic model for optimal control of wildlife damage by migratory small mammal populations is developed under the framework of a nonlinear distributed parameter control problem. The model first simulates the spatio-temporal dynamics of dispersal population by parabolic diffusive Volterra-Lotka partial differential equation and then optimizes...
Article
This paper examines dynamically optimal trapping strategies for a resident beaver population causing damage to privately-held timber land. An extreme elimination strategy does not account for the dispersive behavior of neighboring beaver populations in filling the resulting environmental vacuum. This negative externality is accounted for by embeddi...
