The article analyzes the effects of long term armed conflicts on the characteristics and evolution of traditional land uses. The main focus is on the Umbundu agroforestry system, an endogenous and dynamic traditional African land use in the Angolan Central Highlands, an area that has experienced numerous conflicts during the last 200 years. The study used field research and a literature review to analyze the historical evolution of the system and its recovery after the conflicts. The results provided a characterization of the system's main traits and stakeholders through time. The main focus of the system was maintaining a continuous supply of food crops under changing ownership and security, constrained by soil fertility, and the availability of water and fertilizers. Land use conflicts moulded the system, allowing it to be rich during low and medium intensity conflicts, though constraining it when conflicts escalated to a military civil war. The evolution of the land use system was examined using the frame of multi-functionality. Additional focus is made on its current and future challenges to become a sustainable and profitable agrarian land use system. The study has implications for land use management (e.g. regarding the length of fallow period) as well as conflict management.

Sweet cherry fruit in Norway are graded and packed with chlorinated water according to drinking water standards (max. 2 ppm free chlorine after fruit contact) as a transport medium in parts of the grading lines. A possibility of fruit contamination from fungal pathogens exists in such water. ‘Lapins’ fruit from 10 commercial orchards at each of three packinghouses were put through a simulated sale period (10 days at 2°C and 2-3 days at 20°C) either directly or after being transported on a grading line in 2007. In 2008, fruit were sampled at different times of the day (early, mid and late) and compared with the control. Fruit samples containing 5 x 100 fruits were weighed at time of sampling, after 10 days at 2°C (in a Lifespan bag) and after 2-3 days at 20°C. The number of fruit decayed with fungal pathogens were counted and diagnosed. Total fruit decay in a mean of 3 packing houses x 10 orchards was 14% before packing and 28% after packing in 2007. Brown rot (caused by Monilinia laxa) incidence decreased from 1.1% to 0.3% and Mucor rot (caused primarily by Mucor piriformis) incidence increased from 11% to 26%. In 2008, there were no significant differences between unpacked and packed fruits, or between the different packing hours, on the different fungal diseases or incidence of total fruit decay. These preliminary results indicate that there might be a risk of contamination in seasons with high levels of fruit decay (such as 2007), but in normal seasons a slight chlorination of water is satisfactory to minimize the risk to an acceptable level.
