“…The Kagera region experiences a bi-modal pattern of rainfall (between March and June and from August/September to December) with an annual average ranging from 600 to 2000 millimeters [33,34]. The driest period is from mid-June to mid-August and the second short dry season extends from January to March with daily temperatures ranging from 12 0 C to 34 0 C (average of approximately 21 0 C).…”

Generating evidence of malaria burden in areas with confirmed artemisinin partial resistance (ART-R) is the first step before developing a response strategy to the resistance. In this study, we assessed the burden of malaria in Kagera region (with recently confirmed ART-R) by geospatial analysis using data from health facilities (HFs) and community surveys from 2017 to 2023. In 2983717/8124363 patients from HFs, rapid diagnostic test positivity rate was 36.7% (range: 0-80%) and was similar in patients aged under-fives (33.1%, range: 0-79%) and ≥5 years (33.7%, range: 3-80%). The prevalence of malaria was 10.0% (range: 0-40.5%, n=84999/ 853761) in pregnant women but it was 26.1% (3409/13065) in school children (range: 0-78.4%). We identified hotspots and coldspots, and persistently high burden in 69/192 wards, school children, and patients aged ≥5 years, providing evidence for planning and developing an ART-R response for the region.

“…Phosphorus (P) occurs in limited amounts because of soil erosion, losses and fixation due to high clay content and metal oxides as a result of weathering activities [21,22]. Availability of P for agricultural uptakes in semi-arid soils from P-containing fertilizers depends on the sorption capacity of the soil to hold it from losses, soil pH and metal cations [27,29,31], and the P saturation degree of the soil which determines additional P to be added to the soils and held safely with minimum losses to the environment [29]. Generally, 70-90% of added P through fertilization in soils is fixed depending on soil characteristics, thus decreasing plant available P [4], consequently leading to high P fertilizer application rates in agricultural fields (Bekele et al, 2020).…”

This study was conducted in the Kongwa District to assess the fertility status of soils of the selected fields under maize production to understand fertility variability among soils and recommend appropriate fertilizer rates. The study involved randomly selected 24 maize fields. Composite soil samples were collected in these fields at 0–20 cm deep and characterized for soil fertility status. Results indicated that 48% of the soils were sandy clay loam and 26% were sandy loam. The remaining fields had clay or loamy sand textural classes. The soil pH ranged from extremely acidic (3.52) to moderately alkaline (7.7), organic carbon ranged from very low to medium (0.19-1.60%) and total N were very low to low (0.01-0.15%). Also, results indicated that 42% of soils had P deficiency and 16.7% had inadequate S levels. In addition, 45.8% of the soils had inadequate exchangeable K and exchangeable Mg levels ranged from very low to high (0.29-4.06 cmol(+) kg-1). Exchangeable Ca was low to very high (1.06 to 10.04 cmol(+) kg-1) with favourable base saturation for crop production. The CEC ranged from very low (2.62 cmol(+) kg-1) to medium (18.9 cmol(+) kg-1). Extractable micronutrients such as Cu, Fe, and Mn were adequate but Zn was inadequate in 58% of the soils. Categorizing nutrient status in soils of the study area showed that fertility is poor regarding N, P, K, Zn, Mg, and Ca. Hence, the studied soils need external nutrient inputs and proper management to optimize crop production.
