“…The GHA is one of the regions that have sparse observational weather stations (Dinku et al, 2014;Kondela et al, 2015;Nsabagwa et al, 2016;Dinku, 2019;Mathew, 2022;Tzachor et al, 2023). Since data is key in weather and climate analysis, several interventions have been initiated with an aim of improving climate data services.…”

“…One key gap is related to building the capacity of NMHSs both infrastructurally and in staff skills (Mwesigwa et al, 2015;Lennard et al, 2018;Waruru, 2018;Nsabagwa et al, 2019). Additionally, in most countries over the GHA region the management and maintenance plan/operational procedures for weather and climate observations is relatively weak (Shanko, 2015;Nsabagwa et al, 2016;Aura et al, 2019). For this to be sustainable, governments should provide financial support, through special budgetary allocations, to ensure sustainability of the stations as most synoptic stations are currently not functional (Aura et al, 2019;Mathew, 2022).…”

The Greater Horn of Africa is prone to extreme climatic conditions, thus, making climate services increasingly important in supporting decision-making processes across a range of climate sensitive sectors. This study aims to provide a comprehensive review of the recent advances, gaps and challenges in the provision of climate services over the region, for each of the components of the Global Framework for Climate Services. The study explores various milestones that have been achieved toward climate service delivery. The achievements include improvement of station network coverage, and enhancing the capacity of member states to utilize various tools in data analysis and generate routine climate products. The advancement in science, and availability of High-Performance Computing has made it possible for forecast information to be provided from nowcasting to seasonal timescales. Moreover, operationalizing of the objective forecasting method for monthly and seasonal forecasts has made it possible to translate tercile forecasts for applications models. Additionally, innovative approaches to user engagement through co-production, communication channels, user-friendly interfaces, and dissemination of climate information have also been developed. Despite the significant progress that has been made in the provision of climate services, there are still many challenges and gaps that need to be overcome in order to ensure that these services are effectively meeting the needs of users. The research of the science underpinning climate variability, capacity building and stakeholder engagement, as well as improved data management and quality control processes are some of the gaps that exist over the region. Additionally, communication and dissemination of climate information, including timely warnings and risk communication, require improvement to reach diverse user groups effectively. Addressing these challenges will require strengthened partnerships, increased investment in capacity building, enhanced collaboration between the climate information producers and stakeholders, and the development of user-friendly climate products. Bridging these gaps will foster greater resilience to climate-related hazards and disasters in the Greater Horn of Africa and support sustainable development in the region.

“…We have used a 45Ah battery and 30W solar panel for this use case. Such sizes have domestic value and the meteorological authorities in Uganda and Tanzania have reported vandalism and theft of similar solar panels and batteries to be major challenges [20] [21]. Figure 6 shows a typical way this challenge is wrongly addressed in Uganda-using a secure cage.…”

This paper discusses the various design and operational challenges that we have met in providing power to Wireless Sensor Networks (WSNs) deployed in environment monitoring in East Africa. While such deployments in African environments have a major advantage of abundant sunshine, both in intensity and duration, the same environments still present a number of unique challenges. With the various research initiatives in Africa being quite disjointed, a major problem is the lack of a unified knowledge base that communicates the current challenges and solutions in designing power systems for these WSNs. We implemented a WSN with several autonomous sensors and two types of gateways. We kept track of voltages, uptime and other diagnostic data. We combine our experiences from the study of these devices, and those of some others in the region and other developing countries and make recommendations where we have achieved good results and propose solutions where work is still in progress.

“…Indeed, rain-fed agriculture and agriculture-related production are vital to the Ugandan economy; they averagely employ 80% of the labour force, account for 42% of the GDP, and bring in 90% of export earnings [2] [3]. However, Uganda is in the deficit of a dense rain gauge network and long-term in situ precipitation measurements are required for detailed assessment of her rainfall [4] [5]. The rain fall records are typical of non-continuity with only a few years of quality data, sparse rain gauge network, incomplete, inconsistent and non-reliable datasets.…”
