Read the passage below carefully:
Despite the abundance of flowing river networks in north-central Nigeria, off-grid agrarian communities along the River Niger frequently face severe energy poverty that cripples post-harvest crop processing. Conventional solar installations often prove suboptimal due to high battery replacement costs and seasonal cloud cover. Recently, hydrokinetic river turbines—which generate electricity continuously from natural river currents without requiring dam construction—have emerged as a viable solution. By directly converting kinetic energy into power, these zero-emission systems energize localized agro-milling hubs, significantly reducing grain spoilage. However, seasonal water level fluctuations and floating debris accumulation pose operational challenges, requiring community-led clearing routines and adaptive floating mountings to maintain year-round efficiency.
The sentences below represent synthesized key points from the passage. In what logical sequence should these points be arranged to form the most coherent and concise summary of the text?
- 1Energy scarcity in riverine agrarian communities severely hinders crop processing, while traditional solar power remains cost-prohibitive to maintain.
- 2Hydrokinetic river turbines offer a continuous, zero-emission alternative by harvesting electricity directly from flowing river currents without dams.
- 3This reliable power supply energizes local agro-milling facilities, effectively curbing post-harvest grain losses.
- 4Sustained long-term productivity requires community debris management and flexible mountings to withstand seasonal water fluctuations.
