“…The findings indicate that there are existing information gaps on climate change mitigation policies in the renewable energy sub-sector in Tanzania. From the reviewed literature, most of the studies in the country (by August 2022) were on climate change adaptation (Kangalawe et al, 2011;Ndaki, 2014;Bahati & Kalugendo, 2017;Luhunga, 2018;Said et al, 2019;Shagega et al, 2019;Mourice, 2020;Chang'a et al, 2020;Doughertya et al, 2020;Birthe et al, 2020;Alemaw & Simatele, 2020;Mngumi, 2020;Nyembo et al, 2022;Mswima & Kaswamila, 2022). Where a study focused on climate change mitigation and energy, it was not on mitigation policies in the renewable energy sub-sector (Mwakaje, 2008;Rickerson et al, 2010;Marie-Louise et al, 2011;Ahlborg & Hammar, 2012;Ngaira & Omwayi;Sarakikya, 2015;Wood et al, 2016;Kashwan, 2017;Harnesk & Brogaard, 2017;Obadia et al, 2018;Ngowi et al, 2019;Obadia et al, 2020;Alemaw & Simatele, 2020;Rocco et al, 2020;Mhache, 2021;Olabisi & Richardson, 2022;Bazila et al, 2022;Rugaimukamu, 2022;Kristin, 2022;Mnzava et al;, Adornetto, 2022Gill-Wiehl et al, 2022).…”

“…For instance, Obadia et al (2018) reviewed and examined challenges of the current potential renewable energy for the achievement of sustainable development in Tanzania, but not climate change mitigation policies in the context of promoting renewable energy resources. On the other hand, Wood et al (2016) focused on financing energy access by clean development mechanism using evidence from Tanzania; while Nyembo et al (2022) assessed the impact of climate change on groundwater recharge in the lake Manyara catchment, in Tanzania. Mswima and Kaswamila (2022) assessed the role of ecovillage practices in strengthening climate change adaptive capacity and mitigating desertification in Chololo, Dodoma, Tanzania.…”

Tanzania has the target of reducing greenhouse gas emissions between 30% and 35% by 2030. Renewable energy sources have potential to contribute to reducing greenhouse gas emissions while achieving sustainable development in Tanzania. This paper provides an overview of the public policies in the renewable energy sub-sector in Tanzania. Information on renewable energy, climate change, relevant policies and other related literature were gathered through electronic search and desk review. The retrieved data and information confirm and demonstrate that warming of the climate system is unequivocal due to human induced activities. We note also that renewable energy sources have potential to contribute about two-third of the global total primary energy carbon dioxide emission reduction. Renewable energy may have carbon dioxide savings of the range of global cumulative carbon dioxide from about 220 to 560 GtCO2 in the period of 2010 to 2050. In Tanzania, renewable energy policies would enable the country to contribute to the global goal of reduction of greenhouse gas emissions while achieving its sustainable development according to the national circumstances.

“…Furthermore, changes in species' geographic ranges, growing seasons, reproductive phenology, primary production, and diversity are among the anticipated effects of climate change on water supplies (Fonseca, 2022;Habibullah et al, 2022;Moullec, 2022;Numata et al, 2022;Ornelas et al, 2018). Thus, any change in water resources (i.e., quantity and quality) brought on by the effects of climate change on precipitation might result in biodiversity loss (Fonseca, 2022;Habibullah et al, 2022;Nyembo et al, 2022); change in animal behaviour and physiology (Turner et al, 2022); and many other negative impacts (Table 1).

Climate change-related impacts on water resources can significantly lead to biodiversity loss. Species with specific water resource adaptations, including threatened and endemic species, are in danger of going extinct. The effect of climate change on biodiversity related to water scarcity or shortages has received less attention despite being acknowledged. This paper provides up-to-date collective information and knowledge gap on the impact of climate change on water and how it impacts biodiversity with a particular focus on the connection between climate change impacts, water resources, and the species biodiversity. Sixty (60) original peer reviewed research or review articles, and reports were reviewed to highpoint the impact of climate change on water resources and its implications on biodiversity including human being. We highlight that the impact of climate change on water resources (e.g., water scarcity and shortages) exerts more pressure on biodiversity conservation as it directly affects the growth and behaviour of species and modifies their habitats, population size, composition, interactions, timing of reproduction, reproductive phenology, and growing season. Furthermore, being the part of earth’s biodiversity, humans are also affected by the climate change water-related problems. This review earmarked that water shortages due to climate change puts the human population at great risk in terms of crop productivity, food security, and a variety of economic activities. Well–designed infrastructure to harvest water, mitigate and adapt to climate change is vital for protecting biodiversity from climate risks i.e., water shortages. This review paper is useful to government agencies charged with climate change and environmental conservation and policymakers mostly in developing nations to widen goals where the impact of climate is more noticeable. In addition, several deaths of animals and human due to water shortages have been reported.

“…These effects have been extensively researched in both surface water and groundwater sections, leading to the proposal of strategies for water resource adaptation to climate change. In recent years, there has been a great deal of research on the impact of climate change on water resources, with results indicating the undeniable impact of climate change on water resources and the effect of selecting a climate model and emission scenario on research outcomes (Epting et al, 2021;Costa et al, 2021;Nyembo et al, 2022). Most models have estimated a reduction in groundwater reserves, especially in arid and semi-arid regions, due to decreased precipitation and increased temperatures (Shamir et al, 2021;Amanambu et al, 2020;Majola et al, 2022).…”

In regions with arid and semi-arid climates, groundwater serves as one of the main sources of agricultural, industrial, and drinking water supply, constantly interacting with surface waters. The purpose of this study is to investigate changes in the level and volume of aquifer storage in Kermanshah by simulating the interaction of surface and groundwaters, using a coupling dynamic model WEAP-MODFLOW. This model is capable of calling and automatically running climate change scenarios and displaying their effects on the entire system. In this method, data and results between the MODFLOW and WEAP models are exchanged on a monthly basis, and the impacts of implementing each of the CMIP5 climate scenarios can be observed in both surface water and groundwater sections. The values of recharge, extraction, runoff, river levels, and water supply from the WEAP model are input into the MODFLOW model to calculate groundwater levels and changes in aquifer storage, with results fed back to the WEAP model. To apply model uncertainties and climate scenarios was developed a hybrid model based on the combination of predictions from 5 different AR5 models. The results showed that over a base period of 27 years (October 1991 to September 2018), the average groundwater level at the end of the period decreased by 4.3 meters, with a reservoir volume reduction of 253 million cubic meters. In the event of aquifer operation, based on the predicted climatic parameters derived from the hybrid model during the 81 years (October 2018 to September 2099), the level of reduction and volume of aquifer storage was predicted under the optimistic scenario of RCP2.6 in order of 2.52m and 251.51MCM and the pessimistic scenario RCP8.5, respectively 8.88m and 769.04 MCM. The results demonstrated that employing an integrated operation model in a dynamic link mode is an effective strategy for better river and aquifer management under climate change conditions. The effects of each climate scenario on the entire system are observable in this model, aiding decision-makers in implementing effective adaptation strategies to climate change.
