Abstract Desert locust outbreak in East Africa is threatening livelihoods, food security, environment, and economic development the region. The current magnitude of desert invasion unprecedented has not been witnessed for more than 70 years. Identifying potential breeding sites pest essential to carry out cost-effective timely preventive measures before it inflicts significant damage. We accessed 9,134 occurrence records applied a machine-learning algorithm predict using key bio-climatic...
Integrated Pest Management (IPM) technologies offer effective solutions to reduce the negative effects of crop pests while considering human and environmental health. However, disseminating these faces several barriers, with one most significant being lack farmer awareness regarding their availability, deployment, uptake. Digital tools are perceived as a new form leverage for overcoming barriers. This study analyzes current IPM digital potential boost farmers' deployment adoption...
Abstract. Weeds are one of the major restrictions to sustaining crop productivity. often outcompete crops for nutrients, soil moisture, solar radiation, space and provide platforms breeding pests diseases. The ever-growing global food insecurity triggers need spatially explicit innovative geospatial technologies that can deliver timely detection weeds within agro-ecological systems. This will help pinpoint maize fields be prioritized weed control. Satellite remote sensing offers incomparable...
Monitoring of destructive invasive weeds such as those from the genus Striga requires accurate, near real-time predictions and integrated assessment techniques to enable better surveillance consistent initiatives. Thus, in this study, we predicted potential ecological niche (Striga asiatica) weed Zimbabwe, identify understand its propagation map potentially vulnerable cropping areas. Vegetation phenology remote sensing, bioclimatic other environmental variables (i.e. system, edaphic, land...
After five years of its first report on the African continent, Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) is considered a major threat to maize, sorghum, and millet production in sub-Saharan Africa. Despite rigorous work already conducted reduce FAW prevalence, dynamics invasion mechanisms Africa are still poorly understood. This study applied interdisciplinary tools, analytics, algorithms dataset with spatial lens provide insights project intensity infestation across The data...
Abstract BACKGROUND The cotton jassid, Amrasca biguttula , a dangerous and polyphagous pest, has recently invaded the Middle East, Africa South America, raising concerns about future of other food crops including okra, eggplant potato. However, its potential distribution remains largely unknown, posing challenge in developing effective phytosanitary strategies. We used an ensemble model six machine‐learning algorithms random forest, maxent, support vector machines, classification regression...
The invasion by Striga in most cereal crop fields Africa has posed a significant threat to food security and caused substantial socioeconomic losses. Hyperspectral remote sensing is an effective means discriminate plant species, providing possibilities track such weed invasions improve precision agriculture. However, essential baseline information using remotely sensed data missing, specifically for the Africa. In this study, we investigated spectral uniqueness of compared other co-occurring...
The fall armyworm (FAW), Spodoptera frugiperda J.E. Smith, has caused massive maize losses since its attack on the African continent in 2016, particularly east Africa. In this study, we predicted spatial distribution (established habitat) of FAW five countries viz., Kenya, Tanzania, Rwanda, Uganda, and Ethiopia. We used occurrence observations for three years i.e., 2018, 2019, 2020, maximum entropy (MaxEnt) model, bioclimatic, land surface temperature (LST), solar radiation, wind speed,...
Abstract This special issue presents the outcomes from “ Designing sustainable and circular agricultural systems for year 2100 ,” joint scientific workshop of ISOFAR, Thünen-Institute, INRA-Morocco, which was held November 14 to 16, 2019 in Marrakesh, Morocco. Nineteen scientists a broad array background nationalities came together with understanding that food security globally is at risk, especially post-2050 timeframe. Current concepts, strategies, measures, efforts carried out by...
Agricultural pest management faces mounting challenges with increasing pressure to reduce chemical pesticide use while ensuring food security, and environmental sustainability. Ecologically centered approaches, such as integrated (IPM), offer promising sustainable agroecological crop protection alternative solutions pesticides. This study assesses the investment viability sustainability of two IPM interventions-mango fruit fly (FF-IPM) push-pull technology (PPT) in Kenya Uganda, using...
Push–pull technology (PPT) integrates maize with the legume fodder Desmodium sp. and border crop Brachiaria sp., aiming to enhance production in Rwanda. Despite its potential, adoption of complementary soil management practices (SMP), vital for PPT’s success, remains low. This study employs spatial econometric methods evaluate determinants SMP interdependencies decision-making among PPT-practicing farmers. We constructed a weight matrix based on global Moran’s I index identified optimal...
Virulence is the primary factor used for selection of entomopathogenic fungi (EPF) development as biopesticides. To understand genetic mechanisms underlying differences in virulence fungal isolates on various arthropod pests, we compared chitinase genes, chi2 and chi4 , 8 Metarhizium anisopliae . The clustering showed groups depending their virulence. However, analysis DNA sequences did not reveal major divergences. Although protein translates have been implicated virulence, predicted...
Abstract Striga hermonthica (Del.) Benth is a parasitic weed that damaging major cereal crops in sub‐Saharan Africa (SSA). Although recognised as an agricultural scourge, there limited information available indicating the extent of its growth and spread impacted by changing climate Kenya. This study investigated impact current conditions projected future (2050) change on infestation western Kenya region. Specifically, aimed to predict habitat suitability five counties region through using...
Abstract. Poor crop yields remain one of the main causes chronic food insecurity in Africa. This is largely caused by insect pests, weeds, unfavourable climatic conditions and degraded soils. Weed pest control, based on climate-adapted ‘push-pull’ system, has become an important target for sustainable intensification production adopted many small-holder farmers. However, essential baseline information using remotely sensed data missing, specifically companion crops. In this study, we...
Data mining, particularly the analysis of multivariate time series data, plays a crucial role in extracting insights from complex systems and supporting informed decision-making across diverse domains. However, assessing similarity data presents several challenges, including dealing with large datasets, addressing temporal misalignments, need for efficient comprehensive analytical frameworks. To address all these we propose novel integrated computational approach known as Multivariate Time...
The use of wastewater in urban agriculture has gained a lot interest Senegal. aim this works was to assess the effect on agronomical performance two vegetable crops and hygienic threats as compared tap water. We also irrigation mode addition fertilizers. Results showed that there were no significant differences between modes. Thesturdiness at 2 months had positive number plant (tomato) harvest, yield fruit average weight. Considering following parameters studied (overall yield, corrected per...
Crop cultivation positively or negatively impacts soil biodiversity and associated ecological services. The push-pull technology (PPT), a climate-smart cereal - Desmodium spp.-Brachiaria spp. companion cropping system, is known for providing nature-based solutions pest fertility challenges has been practiced in sub-Saharan smallholder farmer fields more than two decades. However, the extent to which this system affects arthropod general Collembola particular poorly not known. This study...
