This chapter provides information on land suitability and the potential for agriculture and aquaculture in the Darwin catchments. The approach used to generate the results presented in this chapter involves a mixture of field surveys and desktop analysis. For example, the land suitability results draw on extensive field visits to describe, collect and analyse soils that are integrated with state of the art digital soil mapping. Many of the results are expressed in terms of potential. For example, the area of land suitable for cropping or aquaculture is estimated by considering the set of relevant soil and landscape biophysical attributes at each location and determining the most limiting attribute among them. It does not include water availability, cyclone or flood risk, legislative, regulatory, ecological, social or economic drivers that will inevitably constrain the actual area of land that is developed. Crops, forages and cropping systems results are based on data analysis and simulation models and assume good agronomic practices producing optimum yields given the soil and climate attributes in the catchment. Likewise, aquaculture is assessed in terms of potential using a combination of land suitability and productive capacity of a range of aquaculture species. Information is presented in a manner to enable the comparison of a variety of agriculture and aquaculture options. The results from individual components (land suitability, agriculture, aquaculture) are integrated to provide a sense of what is potentially viable in the catchment. This includes providing economic analyses such as gross margins (crops); how with the advantage of irrigation more intensive rotational cropping systems might be feasible; specific information on a wide range of crop types for agronomy, water use and land suitability for different irrigation types; and integrating agriculture and aquaculture to provide value-add within the catchment.
