“…The two are the leading avocado-producing regions in their respective countries, with Murang’a County accounting for 46.9% of the total avocado production in Kenya [ 3 ], while Kilimanjaro Region, specifically Siha District accounts for about 54% of the avocado production in Tanzania [ 6 , 37 ]. Using a multi-stage sampling procedure, a random sample of 410 [ 38 ] and 420 avocado-growing households were selected for the baseline survey in Kenya and Tanzania respectively. To assess the potential adoption of IPPM, their preferences for either the innovation in isolation (i.e.…”

“…IPM or pollinator supplementation (managed Western honey bee ( Apis mellifera ) hives) or integration of both (i.e. IPPM), were first determined [ 38 ]. Upon selecting the most preferred option, the respondents’ willingness to buy the selected option based on the current cost of pesticides for the management of the target pests and disease was elicited.…”

Using synthetic pesticides to manage pests can threaten pollination services, affecting the productivity of pollination-dependent crops such as avocado. The need to mitigate this negative externality has led to the emergence of the concept of integrated pest and pollinator management (IPPM) to achieve both pest and pollinator management, leading to complementary or synergistic benefits for yield and quality of the harvest. This paper aims to evaluate the potential economic and welfare impact of IPPM in avocado production systems in Kenya and Tanzania. We utilize both primary and secondary data and employed the economic surplus model. On average the potential economic gain from the adoption of IPPM is US$ 66 million annually in Kenya, with a benefit-cost ratio (BCR) of 13:1, while in Tanzania US$ 1.4 million per year, with a BCR of 34:1. The potential benefits from IPPM intervention gains are expected to reduce the number of poor people in Kenya and Tanzania by 10,464 and 1,255 people per year respectively. The findings conclude that policies that enhance the adoption of IPPM can fast-track economic development and therefore improve the livelihoods of various actors across the avocado value chain.

“…This ESA-derived LULC dataset was derived from a one-year of Sentinel-2A observations from December 2015 to December 2016 classified using the RF algorithm (ESA, 2020). Other studies on bees or other insect species have demonstrated the interdependence of land cover patterns and insect species, regarding their relative potential spatial distribution (Adan et al, 2021;Nyabako et al, 2020;Ropars et al, 2020). However, these regionally developed datasets such as the Sentinel-2 prototype land cover data for Africa used in this study often have accuracy limitations.…”

“…Normalized Difference Vegetation Index (NDVI) images available from NASA’s Land [ 58 , 59 ], Atmosphere Near real-time Capability for EOS (LANCE) and data from Group on Earth Observation Global Agricultural Monitoring (GEOGLAM) [ 60 ] provide important data on green vegetation density, mapping the regions where plants/crops are thriving and where they are under stress (i.e., due to lack of water). Aside from soil moisture, satellite imagery has been used in determining other soil parameters, such as carbon content, salinity, pH, temperature [ 56 , 61 , 62 ], detection of pests, diseases, and pollinators [ 63 , 64 ], prediction of crop yield and natural disasters, and phenotyping of crops [ 65 , 66 ]. Although it may seem appealing to use these methods due to the scale of the measurements, they have course spatial and temporal resolution and are restricted to shallow penetration.…”

Soil nutrients assessment has great importance in horticulture. Implementation of an information system for horticulture faces many challenges: (i) great spatial variability within farms (e.g., hilly topography); (ii) different soil properties (e.g., different water holding capacity, different content in sand, sit, clay, and soil organic matter, different pH, and different permeability) for different cultivated plants; (iii) different soil nutrient uptake by different cultivated plants; (iv) small size of monoculture; and (v) great variety of farm components, agroecological zone, and socio-economic factors. Advances in information and communication technologies enable creation of low cost, efficient information systems that would improve resources management and increase productivity and sustainability of horticultural farms. We present an information system based on different sensing capability, Internet of Things, and mobile application for horticultural farms. An overview on different techniques and technologies for soil fertility evaluation is also presented. The results obtained in a botanical garden that simulates the diversity of environment and plant diversity of a horticultural farm are discussed considering the challenges identified in the literature and field research. The study provides a theoretical basis and technical support for the development of technologies that enable horticultural farmers to improve resources management.
