Human resources development for sustainable aquaculture in the new millennium

Human resources development (HRD) is pivotal to aquaculture development in the new millennium, particularly so in the changing global pressure for all development to be environmentally and socially acceptable, irrespective of the economic status of nations. In the above context, HRD in the aquaculture sector has to have a more holistic approach, and the type of training provided has to be changed accordingly. Most nations in which aquaculture plays a significant role in poverty alleviation recognise that HRD is a key to sustained development of the sector. The types and levels of training required in the sector in the foreseeable future are discussed. The need to increase specialised training, particularly for researchers, in some of the developing nations likely to play adominant role in the aquaculture sector in the ensuing years, is also underlined. Examples are presented to indicate that current development programmes do not cater to HRD to the extent that is desirable to have a long-term impact.

Artikel 3(1) en (2) van die Mineral and Petroleum Resources Development Act 28 van 2002: 'n herbeskouing

Sections 3(1) and 3(2) of the Mineral and Petroleum Resources Development Act 28 of 2002
This contribution entails a discussion of the impact of section 3 of the Mineral and Petroleum Resources Development Act on various aspects of the new mineral and petroleum law. At the core of the discussion is the question of how this section is interpreted by various commentators, and the implications of the different opinions on the application of the section. The initial discussion highlights problems with the new definition of a "mineral": Soil, including topsoil is at present included in die definition of a "mineral" in the act. The definition should be rectified by the legislature as it has far-reaching consequences in respect of the extent of the state's power in terms of section 3(2) of the act to grant entitlements in respect of minerals, including topsoil. The implications of section 3 for the control and management of minerals are discussed and placed in the context of the question about the constitutionality of the act. It is argued that legislative guidance is urgently needed to clarify continuing uncertainty, caused by sloppy drafting and different opinions about the connection between private law and public law in relation to minerals and the actual position of existing right holders.

Influence of land cover on water resources

The influence of land cover on water quality and quantity was examined using a multidisciplinary approach that integrated land use maps, historical databases, and statistical modelling. Systematic changes in the Glenelg Hopkins landscape were identified, in addition to a relationship between greater proportions of vegetation and better water quality.

The four national taps of Singapore: a holistic approach to water resources management from drainage to drinking water

 Water resources in Singapore are managed following the principles of a closed loop hydrologic cycle by one agency, the Public Utility Board (PUB), which promotes its management philosophy through the Four National Taps of Singapore program. The four national taps are: water from local catchment areas; imported water (from Malaysia); reused water (known as NEWater); and desalinated water. Given the uncertainty of water imports, the remaining three national taps have become increasingly important and this paper begins with a general overview of the innovative programs implemented by PUB in support of these three taps. Stormwater runoff is captured from two-thirds of Singapore’s land area and stored in reservoirs for subsequent use. Stormwater management is an important component of the catchment area tap and extensive low impact development (LID) implementation has become a priority through the ABC (Active, Beautiful, Clean) Waters Program. Examples of several ABC Waters projects are discussed. NEWater currently supplies 30% of the country’s demand and this is projected to increase to 50% by 2060. NEWater plants take treated wastewater through the additional steps of microfiltration, reverse osmosis and ultraviolet treatment for use primarily in industry, although a portion also is blended into the municipal reservoirs. Singapore’s single desalination plant currently meets 10% of its demand, with a second plant to be completed in 2013 that will more than double production. Also discussed are the results of recently completed pilot projects related to stormwater management including testing of E. coli in runoff from high density residential areas, a blind taste test and survey on acceptance of NEWater, and a survey of Singaporean understanding about stormwater management issues.Water resources in Singapore are managed following the principles of a closed loop hydrologic cycle by one agency, the Public Utility Board (PUB), which promotes its management philosophy through the Four National Taps of Singapore program.

Tensions and dilemmas in community development: new discourses, new Trojans?

This paper begins by noting the range of contradictions and dilemmas facing those involved in community development today. It then draws on research into the operating frameworks that set the stage for much current community development activity. It discusses four key operating frameworks and how each framework can affect community development practice. The final section deals with the ways in which the frameworks, and the discourses associated with them, come together.

"Minerals", "petroleum" and "operations" in the Mineral and Petroleum Resources Development Act 28 of 2002 : a geologist as devil's advocate for a change? "

This article examines the meaning of "minerals", petroleum, "operations" and activities in relation to such substances to determine the ambit of the application of the Minerals and Petroleum Resources Development Act 28 of 2002, the type of rights necessary for such operations and activities and the ambit of these rights. The examination of the meaning of these concepts takes place with reference to prior definitions in statutes and also from a natural science and geology perspective. An attempt is made to show that the legal definitions do no always correspond with the geological meanings and the meanings on the ground. It is questioned whether in recent legislation why more reliance is not placed on input from geologists in the field.

Entrepreneurship policy development : New Zealand in comparison

This paper first examines the impact of entrepreneurship research on policy development in 20 countries of the Global Entrepreneurship Monitor project. Curiously, despite its entrepreneurial endowments, the impact on New Zealand falls behind other countries. For a deeper insight, the paper then compares entrepreneurship and innovation policies in New Zealand and Sinaloa, Mexico. New Zealand has a robust innovation policy yet places little emphasis on the needs of actual individual entrepreneurs and their decision to choose self-employment. In Sinaloa, the emphasis is on creating more and better entrepreneurs, but there is no innovation policy. Both sides have something to learn from the other.

Water, escaping sovereignty : the hydropolitics of the Tigris-Euphrates river and Turkish state formation

Develops a critical analysis of the domestic and international factors influencing the process of Turkish state formation. Focuses on the political economy of water resource development along the Tigris-Euphrates river basin, shared by the three riparian states, Turkey, Iraq and Syria. Turkey's large-scale development of the river is characterised as a state making imperative, highlighting the needs to improve regional resource diplomacy.
