The sustainable development in the Sartenejan region requires maximising the potentials of agriculture, fisheries, eco- and scientific tourism, real estate, building, and energy supply. Niche markets can be developed to maximise profits and employment.

The sustainable development of these industries will provide a range of employment opportunities.

Improved facilities include services such as cheaper and more reliable electricity, better roads, and affordable garbage collection, more and better shops, restaurants, and entertainment. There will also be a more widely experienced and better trained workers skill base.

Niche markets could be within the Sartenejan region, retail Belize, tourist resorts, or internationally. Products include the sustainable development of new manufacturing industries, the production of specialised fruit trees and crops, aquaculture, and small scale livestock production.

Secondary products such as jams, spices, and food bars provide increased employment and are marketable with good branding. Both primary and secondary products are often successfully marketed through using branding that includes special locations, flavours or health benefits.

Sarteneja is an ideal location for the sustainable development of solar energy, both for heating water and for electricity. Sarteneja is the sunniest region on mainland Belize, and the long transmission lines to Sarteneja result in considerable loss of electricity (see Solar Energy). The use of wood fuel provides a sustainable energy source.

Sustainable development encourages the preservation of natural forest to maintain the beauty of the region, biodiversity, and rainfall, and to reduce wind damage and provide for water tables.

As the region sustainably develops the maintenance of both forest  and biodiversity will increasingly support higher land values and tourist potential.

To save cost and minimise pollution, chemical fertilisers, herbicide's, and pesticides should be used sparingly and organic farming methods used where practicable.

On a world scale the Sartenejan region is a very low producer of greenhouse gasses that increase global climate warming. To minimise greenhouse gas emissions for transport use bicycles if possible or vehicles that use the minimum fuel. Travel on busses rather than driving.

Recent and new house construction is largely concrete beam/block design with concrete roofs. These houses are structurally hurricane resistant, however, they tend to hold heat. Air conditioning is expensive and uses a lot of electricity. Cost efficient architecture that minimised heat intake by the house and maximised the control of ventilation could cool houses.

Sustainability includes problems shared between regions such as climate change and long term air born pollutants. However, each region has its particular opportunities for to build sustainability. For example, the high amount of sunshine in some locations makes them ideal for the development of solar energy.

In Central America soot from forest burning can be reduced in concert with forest retention. Soot contributes 30% to global warming. Soot quickly leaves the atmosphere so is effect is very short term. This means the positive effects of decreased atmospheric soot on reducing global warming is almost immediate. We are working on improved agricultural systems that increase income while reducing the need for forest clearance and burning. Minimising soot production through reduced burning would provides Sarteneja an opportunity to immediately reduce the rate of global warming and retian forest.

Further benefits of reducing burning are through the unburned vegetation acting as mulch. Mulch adds nutrients to the soil, and reduces nutrient loss, weeding, and water loss. Plant growth can greatly increase especially during dry periods as soil nutrition and water availability increase. This reduces the time before first production and increases crop yields and quality.

The sustainable development of the Sartenejan region will provide increased facilities, an improved environment and economy, more opportunities for youth employment in a career position.
