Abstract

Lack of improved water, sanitation, and hygiene (WASH) is a high risk for people who are living in urban and rural areas in Svay Rieng province. This study has three objectives: (a) to assess the current impact of climate change on rural WASH; (b) to examine the adaptation systems of rural WASH as they respond to climate change; and (c) to determine the elements of appropriate mechanisms and supporting systems for the sustainability of rural WASH's climate change adaptation. As a methodology, this research surveyed 136 samples from 8 districts in Svay Rieng province. The results found that knowledge and awareness of people on climate change were at 92.65%. The main factors that cause climate change are burning fossil fuels like oils, gasoline, and coal. The sensitive sectors impacted by climate change are water and sanitation. There are two kinds of elements: appropriate mechanisms and supporting systems for the sustainability of rural water supply. To improve future rural WASH in local communities and adaptation to climate change, people should focus on using high-tech infrastructure for water supply stations such as safe water pipe systems, water treatment stations, pump wells, and ponds that are resilient and adapt to climate impact.

Abstract

The complexities of climate change are well-known, and it has immediate and long-term consequences on the environment and natural resources. This global concern adversely affects sustainable development sectors and economic systems including the agricultural sector. The tea sector is among the largest export crops contributing to earnings and revenues. Its production has been declining, and the reasons behind this decline remain unclear. This study proposed to explore the influences of climate variability on the current productivity trend of smallholder tea farmers in Tanzania. The study involves quantitative data analysis, collected from 1990 to 2020 including monthly precipitation, temperature statistics, and Greenleaf production gathered as secondary data from the Tea Research Institute of Tanzania and the Tea Board of Tanzania. The study found that rainfall and temperature change significantly influence smallholder farmers' tea production in the East Usambara Mountains. The optimal climate elements (temperature and precipitation) positively improve smallholder farmers' tea production. In contrast, extreme climate variability triggers negative effects on tea production when precautions and adaptation measures are not considered. To summarize, it is recommended that farmers engage in different programs and training sessions to enhance their perception and adaptability to climate change.
