  • IMPROVING INTEGRATED PRODUCTION AND PEST MANAGEMENT OF RICE FOR CLIMATE CHANGE ADAPTATIONS IN UGANDABosco Bua, (PhD), Principal InvesigatorProject team 1.

Akasairi Ocwa, Undergraduate studentAbstractRice plays a central role in the economy of Uganda both as a food staple and source of cashincome for the majority of the population. Traditionally, lowland ecosystems have been thehome of rice production offering a stable water and nutrient supply. However, lack of water,greenhouse gases emissions, pests and diseases limit rice production in many parts of the worldincluding Uganda. Therefore, with the variability and change in climate, rice production isexpected to further decline due to a host of other production constraints. In fact, rice is both avictim and a contributor of climate change. Thus, any significant negative effect on riceproduction caused by climate change would be devastating for efforts to achieve national foodsecurity and address poverty. Therefore, there is need to produce rice varieties with improvedresistance to insects and diseases as well as water and nutrient use efficiencies among otherattributes. Indeed, new environmental conditions and shifts in production practices that farmersmay adopt to cope with climate change effects leading to improved integrated production andpest management of rice for climate change adaptations is urgently required. In fact, selection ofhigh yielding rice varieties that are; resistant to rice diseases, resilient to moisture stress,acceptable to the consumers, improved rice production systems for sustainable use that can copewith changing climate conditions is the answer. Studies are therefore being undertaken to 1)screen advanced breeding lines and local landraces for resistance to pests and diseases, 2) assessthe effects of water management practices on greenhouse gases emissions, and 3) assess theeffects of disposable rice residues on the greenhouse gases emissions and pests and diseasesdynamics in Uganda both in the screenhouse and field. In addition, laboratory analysis is beingundertaken to assess the soil carbon and nitrogen status of the fresh paddy soils and the usedpaddy soils as well as plant samples. Data collected on pests, disease incidence and severity andyield during first season of 2011 are being compiled for analysis. In general, the studies will berepeated for two more times during first and second seasons 2012, respectively.
