This guideline jointly published by The UN Economic and Social Commission for Asia and the Pacific (ESCAP), the UN Economic Commission for Latin America and the Caribbean (ECLAC), and the UN Human Settlements Programme (UN-HABITAT), in partnership with the Urban Design Lab of the Earth Institute, Columbia University, provides practical tools for city planners and decision makers to reform urban planning and infrastructure design according to the principles of eco-efficiency and social inclusiveness. It includes case studies from the Republic of Korea, the Philippines, Japan and Sri Lanka.

This occasional paper examines the experiences of three leading global centres of the ICT industry – India, Silicon Valley, and Estonia – to reflect on how the lessons of these models can be applied to the context of countries in the Caribbean region.Several sectors of the technology industry are considered in relation to the suitability for their establishment in the Caribbean. Animation is an area that is showing encouraging signs of development in several countries, and which offers some promise to provide a significant source of employment in the region. However, the global market for animation production is likely to become increasingly competitive, as improved technology has reduced barriers to entry into the industry not only in the Caribbean, but around the world. The region’s animation industry will need to move swiftly up the value chain if it is to avoid the downsides of being caught in an increasingly commoditized market. Mobile applications development has also been widely a heralded industry for the Caribbean. However, the market for consumer-oriented smartphone applications has matured very quickly, and is now a very difficult sector in which to compete. Caribbean mobile developers would be better served to focus on creating applications to suit the needs of regional industries and governments, rather than attempting to gain notice in over-saturated consumer marketplaces such as the iTunes App Store and Google Play. Another sector considered for the Caribbean is “big data” analysis. This area holds significant potential for growth in coming years, but the Caribbean, which is generally considered to be a datapoor region, currently lacks a sufficient base of local customers to form a competitive foundation for such an industry. While a Caribbean big data industry could plausibly be oriented toward outsourcing, that orientation would limit positive externalities from the sector, and benefits from its establishment would largely accrue only to a relatively small number of direct participants in the industry. Instead, development in the big data sector should be twinned with the development of products to build a regional customer base for the industry. The region has pressing needs in areas such as disaster risk reduction, water resource management, and support for agricultural production. Development of big data solutions – and other technology products – to address areas such as these could help to establish niche industries that both support the needs of local populations, and provide viable opportunities for the export of higher-value products and services to regions of the world with similar needs.

Water security which is essential to life and livelihood, health and sanitation, is determined not only by the water resource, but also by the quality of water, the ability to store surplus from precipitation and runoff, as well as access to and affordability of supply. All of these measures have financial implications for national budgets. The water sector in the context of the assessment and discussion on the impact of climate change in this paper includes consideration of the existing as well as the projected available water resource and the demand in terms of: quantity and quality of surface and ground water, water supply infrastructure - collection, storage, treatment, distribution, and potential for adaptation. Wastewater management infrastructure is also considered a component of the water sector. Saint Vincent and the Grenadines has two distinct hydrological regimes: mainland St Vincent is one of the wetter islands of the eastern Caribbean whereas the Grenadines have a drier climate than St Vincent. Surface water is the primary source of water supply on St Vincent, whereas the Grenadines depend on man-made catchments, rainwater harvesting, wells, and desalination. The island state is considered already water stressed as marked seasonality in rainfall, inadequate supply infrastructure, and institutional capacity constrains water supply. Economic modelling approaches were implemented to estimate sectoral demand and supply between 2011 and 2050. Residential, tourism and domestic demand were analysed for the A2, B2 and BAU scenarios. In each of the three scenarios – A2, B2 and BAU Saint Vincent and the Grenadines will have a water gap represented by the difference between the two curves during the forecast period of 2011 and 2050. The amount of water required increases steadily between 2011 and 2050 implying an increasing demand on the country‘s resources as reflected by the fact that the water supply that is available cannot respond adequately to the demand. The Global Water Partnership in its 2005 policy brief suggested that the best way for countries to build the capacity to adapt to climate change will be to improve their ability to cope with today‘s climate variability (GWP, 2005). This suggestion is most applicable for St Vincent and the Grenadines, as the variability being experienced has already placed the island nation under water stress. Strategic priorities should therefore be adopted to increase water production, increase efficiency, strengthen the institutional framework, and decrease wastage. Cost benefit analysis was stymied by data availability, but the ―no-regrets approach‖ which intimates that adaptation measures will be beneficial to the land, people and economy of Saint Vincent and the Grenadines with or without climate change should be adopted.
