A RECURRING CHALLENGE OF RESOURCE POLICY IN CANADA HAS BEEN TO BALANCE INTERRELATED POWER WHEN THERE IS DIVERGENCE IN THE GOALS OF PROVINCIAL AND FEDERAL GOVERNMENTS. CONSTITUTIONAL AMENDEMENTS IN 1982 AND FEDERAL-PROVINCIAL NEGOTIATIONS IN THE 1970S AND THE 1980S CONFIRMED THE NEED FOR ACCOMMODATION. THE RESULT WAS TO STRENGTHEN THE DECENTRALIZATION OF MANAGEMENT, YET TO RECOGNIZE THE LEGITIMACY OF THE INTERESTS OF BOTH ORDERS OF GOVERNMENT. ESPECIALLY WITH THE EMERGENCE OF NEW TYPES OF INTERESTS IN THE RESOURCE SECTOR, OCCASIONAL FRICTIONS MAY BE ANTICIPATED BECAUSE OF THE INTERRELATEDNESS OF POWERS.

Ergebnisse einer empirischen Studie in KwaZulu über die Agrarstruktur im Subsistenzbereich. Befragt wurden 70 Haushalte im Distrikt Nkandla. Zwar wurde kein Vieh auf dem Markt verkauft, doch konnte der Verbrauch von Fleisch und Geflügel bewertet werden. Grundnahrungsmittel ist Mais; Produktionssteigerungen werden durch geringe Bodenfruchtbarkeit beschränkt. Weitere Probleme: starkes Unkrautwachstum und Benutzung traditionellen Saatguts. Vorgeschlagen wird das Anpflanzen von Nutzholz und Obstbäumen. (DÜI-Wsl)

AbstractWater treatment plants traditionally use coagulation/flocculation process to remove organics and turbidity particles in drinking water. As a result of the chemical optimisation of the coagulation process having such a strong influence, it is believed that the current hydraulic conditions for flocculation cited under best practice could be out of date. A 450 Mld plant treating upland water was chemically optimised, and it was observed that the total mixing energy input could be reduced by 66% without any detrimental impact upon the clarified water being observed. Under the new mixing regime, energy costs could be reduced by £37 300 pa equating to approximately a 280 t reduction in CO
