“…Further, these strategies may also constrain (−1) the achievement of households' food security (SDG 2.1.2), the income of small-scale farmers (SDG 2.3.2), poverty reduction (SDG 1.1.1 and 1.2.1), and reducing undernourishment (SDG 2.1.1) (see Figure 6 and Table 4). Despite the importance of these strategies, they may not be effective during the severe decline in rainfall [9]. For example, during the household survey, some farmers complained that they planted early-maturity crops, but they dried up due to a lack of rain.…”

“…Agroforestry can improve soil fertility, enhance system resilience to climate change, reduce greenhouse gases, and maintain biodiversity on farmland (SDG 2.4.1) and the patterns that increase agricultural productivity and households' income (SDG 2.3.2), food security (SDG 2.1.2), and poverty reduction (SDG 1.1.1 and 1.2.1). Despite the importance of agroforestry, they still need water to provide better yields [9]. Hence, they may still offer limited additional benefits during times of severe decline in rainfall leading to food insecurity (SDG 2.1.1 and 2.1.2), a decrease in households' income (SDG 2.3.2), and an increase in poverty (SDG 1.1.1 and 1.2.1) [25].…”

“…Further, there are scant empirical studies on interactions between adaptation strategies recommended for farmers and their contributions toward achieving SDGs (1: no poverty and 2: zero hunger) in Africa, particularly in Tanzania. SDGs 1 and 2 are the most critical goals in Africa as the region is the poorest and most food insecure globally [9]. Agriculture is the primary economic activity, which employs many people on the continent, and is considered an important sector in alleviating poverty, ending hunger, and achieving food security [9].…”

This study investigated the potential adaptation measures for farmers in the Mwanga and Same Districts of Tanzania and then assessed their positive and negative interactions towards potential contributions to the selected sustainable development goal (SDG) indicators of no poverty and zero hunger. A total of 200 household surveys were conducted, and 36 participants were interviewed as key informants. Moreover, four focus group discussions were conducted to identify potential adaptation strategies in the studied areas. The literature and expert judgement approaches were used to understand and assess the positive and negative interactions between adaptation strategies and the selected indicators of SDGs. A seven-point scale of SDG interactions was used to determine the interactions between identified adaptation strategies and selected SDG indicators. Qualitative data were subjected to content analysis, whereas quantitative data were analyzed through descriptive statistics. The finding revealed that some of the adaptation strategies (i.e., stream bank crop cultivation, valley bottom crop cultivation, and cultivating crops near water sources) considered potential at the household levels and had strong negative interactions on achieving SDG 2.4.1. Further, most farmers hardly employed strategies (i.e., use of extension officers, concrete irrigation channels, crop insurance schemes, and credit schemes) that had strong positive interactions on the selected SDG indicators. Moreover, most of the identified strategies (i.e., early maturity crops, planting drought-resistant crops, use of improved varieties, mixing improved and local varieties, mixing short and long duration varieties, and crop diversification) are enabling strategies (+1), which, despite their importance, may constrain (−1) the income of small-scale farmers, food security, and poverty reduction. The importance of other strategies (i.e., irrigation infrastructures) must be addressed for better yields and positive impacts. Hence, achieving SDGs 1 and 2 in the studied areas will require the integration of different adaptation strategies that complement each other, and not by promoting only some strategies as used or suggested before. For example, the emphasis on using improved varieties and crop diversification should be complemented by access to credit schemes, irrigation infrastructures, crop insurance, and extension services at the village level.

“…The mitigation and adaptation of crop varieties and management, water and soil management, financial schemes, migration, and culture, and finally agriculture and weather services are four themes that can be used to group strategies to reduce the effects of climate change on farms in Africa, possibly Asia, and other parts of the world (Magesa et al, 2023).…”

The global temperature increase of 1.1°C over the past decade and human population growth are already escalating competition for water in locations where water is scarce, adversely affecting agriculture. Water-smart farming was developed to address challenges associated with the availability, access and use of agricultural water. It complements practices and goals related to agricultural water in climate-smart agriculture. It encompasses several climate-responsive food cropping systems, water-saving methods, tools, and technologies to grow food sustainably. Effective implementation of water-smart farming can ameliorate the pressing burden of agricultural water competition. Therefore, the conceptual framework of water-smart farming and its principal elements or ideology are introduced in this review. The major pillars of water-smart cropping, which include conditioning and improving the soil’s capacity to capture and hold moisture, basic infrastructure for water harvesting, storage and use as nature-based cropping solutions were elaborated. Further examples of technologies and best practices in water-smart crop farming, such as breeding for drought-tolerant crop varieties, promoting dryland cropping systems, alternate wetting and drying technology, water drainage and control structures, rainwater harvesting, utilization of irrigation reservoirs, cover cropping and intercropping for enhancing soil moisture conservation were presented. The review also briefly shows the contribution of some of these best practices and adaptive technologies of water-smart cropping toward promoting water-saving methods used for growing rice, maize, legumes, cassava and peri-urban vegetables.

Water availability and quality are fluctuating due to climate change, which has disastrous effects on life. Modeling climate change impact on streamflow in the Lake Tana sub‐basin (LTSB) in selected watersheds was the main goal of the research. This research is unique in that it applies the coupled MIKE SHE/MIKE HYDRO model technique, which has not been applied before to investigate changes in streamflow due to climate change in LTSB. Streamflow in the LTSB was forecasted using the MIKE SHE/MIKE HYDRO model from seven ensembles of GCMs under two emission scenarios (SSP2–4.5 and SSP5–8.5) between 2041 and 2,100. According to the calibration and validation results in the period of 1985–2007, MIKE SHE performs well while simulating streamflow in LTSB. During calibration and validation, the Nash‐Sutcliffe efficiency (NSE) values in all watersheds were greater than 0.8, except for the Ribb watershed calibration, where it was 0.75. The mean monthly changes in temperatures indicate an incremental tendency in the next decades. According to the simulation result, the monthly mean rainfall for SSP2–4.5 and SSP5–8.5 will increase from 0.05 to 61.9% and 2.02 to 46.26% in the 2050s and 8.7 to 44.38% to 6.44 to 66.24% in the 2080s, respectively. Gilgle Abay, Gumara, and Ribb watersheds will lose 56.2, 56.65, 57.01% of their mean monthly streamflow in the 2050s, according to SSP2–4.5. For the Gilgle Abay, Gumara, and Ribb watersheds, streamflow will increase by 6.7% to 21.94%, 6.08% to 23.26%, and 6.51% to 22.88%, accordingly, in the 2050s under SSP5–8.5. Increased rainfall in the watershed could result in floods in the already‐flooded Gumara and Ribb flood plains. The government and community should implement coping mechanisms to lessen the impact of climate change like early warring and planting more trees. Overall, the study showed that it is expected that conditions related to streamflow may change in the future due to climate alteration. By offering a better understanding of current and future climates, the integrated modeling system developed can assist environmentalists, hydrologists, and policymakers in water management and policy intervention.
