    Effectiveness of traditional approaches in management of desert locust(Schistocerca Gregaria Forskal) in arid areas of Isiolo and Laikipia Kenya
    (Uganda Martyrs University, 2024) Mwikali, Pamela; Musinguzi, Simon Peter; Mwamburi, Lizzy
    The Horn of Africa has witnessed an upsurge in desert locust invasions (Schistocerca gregaria Forskål). Curiously, the first-line of management is often based on traditional methods. We assessed the effectiveness the traditional methods of desert locust control in two rural arid areas in Kenya between 2019 and 2020 using a questionnaire survey. Large swarms of desert locusts were observed during the migratory, feeding, and developmental stages during the driest months. Most of the identified stages were adults and 3rd nymphal instars. The past desert locust preventive strategies among the respondents were early planting, high seed rates, early warning strategies, and information interchange. The physical/mechanical control strategies used by the respondents during the outbreaks included digging up eggs, handpicking, smoking, and baiting. The cultural desert locust control strategies used by the respondents were noise from beating drums, metallic containers, and motorbike hooting. These methods had low effectiveness in controlling desert locust populations. Traditional methods of locust control should not rely solely on desert locust management. There is a need to integrate these traditional methods with new methods for desert locust control only when the swarms are low.

    Income and price elasticities of household electricity demand: a comparative systematic review of aggregated and disaggregated data studies
    (Elsevier, Science Direct, 2024-12) Mubiinzi, Geoffrey; Senyonga, Livingstone; Kigongo Kaawaase, Twaha; Wasswa, Francis; Adaramola, Muyiwa S.; Nantongo, Maria
    This systematic review investigates disparities in research coverage and assesses the implications of income and price elasticities on household electricity demand. By analyzing studies across various regions and income groups, it aims to uncover imbalances in research distribution and understand their impact on energy policy development. The review employs a systematic approach, analyzing peer-reviewed and gray literature from Scopus, Web of Science, and Google Scholar databases from 1980 to 2023. It addresses four research questions: regional and income group classifications, differences in income elasticities, variations in price elasticities, and the accuracy and variability of household electricity demand elasticity estimates between aggregated and disaggregated data studies. The review reveals significant imbalances, with the Middle East, North Africa, and Sub-Saharan Africa underrepresented, while Europe and Central Asia exhibit robust research. Consistent inelasticity in electricity demand is observed across contexts and timeframes. High-income countries dominate this research, leading to a lack of empirical studies in low-income regions, hindering tailored interventions. Understanding short- and long-run elasticities is crucial for effective demand forecasting and policy design. This review uniquely compares income and price elasticities from aggregated and disaggregated data studies, highlighting regional research disparities and their implications for energy policy. It emphasizes the need for inclusive, context-specific investigations to foster sustainable development and equitable energy access globally.
