“…This is supported by the findings of Antwi-Agyei and others [4]. When smallholder farmers increase the size of cultivable land to include fallow and virgin lands, as identified by Baruah and others [11], it leads to significant increase in crop yield and promising for food crop sustainability. Moreover, these local practices were never panaceas but rather requires careful application/usage to attain the desired output.…”

“…Some scholars have also drawn the attention of climate change scholars to the uneven geographies of climate change impacts, by showcasing the disparities in the vulnerability of farmers across geographies [3,50]. In doing so, they brought to light the manifold climate-related factors that act as drawbacks to the food crops production of smallholder farmers [11]. Climate change scholars have also showcased the insurgent and the diversity of measures that farmers undertake to limit the vulnerabilities that arise from climate change, including the Sustainable Intensification Agriculture and Ecological Intensification Agriculture [2,15,32,38].…”

Navigating complexities towards sustainable food crops production: local practices for climate change adaptation in rural Ghana

Globally, food crops production has been challenged by the impacts of climate change. Climate change scholars have argued that rural dwellers, particularly smallholder farmers who engage in food crops production, suffer the most due to their low capacity to adapt. A growing body of knowledge also suggests that local practices serve as safeguards, that enable smallholder farmers to lessen their vulnerability in food crops production. However, limited scholarly insight has been advanced about sustainable food production via the use of local practices. Through the mixed research approach, the study contributes to local practices and climate adaptation debates by examining the various local practices of smallholder farmers, the challenges they encounter with the use of such practices and the possibility for sustainable food crops production in the future in Ghana. The findings suggest that smallholders encounter multiple drawbacks in attempt to utilize local practices to adapt food crops production to climate change including the advent of modern farming inputs/practices. Even when multiple local practices (the planting of multiple crops’ varieties, switching between crops and livestock rearing, reducing cultivatable land size) are utilized, only the increment in farm size, the use of income/remittances of rural–urban migrants to support food crops production, and early cultivation offered some possibilities of sustaining improvement in food crops production for the future. Therefore, the study concluded that local practices are not necessarily panaceas for sustaining food crops production under climate change. The study recommended that further studies pay attention to the sustainability of local practices under climate change.

“…The increasing temperature and the changes in the precipitation intensity or frequency affect the magnitude and the intensity of the floods [13]. The annual mean temperature of the upper Brahmaputra valley region has increased by 0.15 • per decade from 1971 to 2007, while rainfall in the summer season has marked a decreasing trend [14]. The study on the seasonal and annual rainfall extent over the Indus, Ganga, and Brahmaputra River basins using the Tropical Rainfall Measuring Mission (TRMM) data of 1998 to 2017 indicated a significant decreasing trend of rainfall in the eastern part of the Indus-Ganga-Brahmaputra (IGB) basins and an increase towards the western part [15].…”

The Ganga-Brahmaputra basin is highly sensitive to the impacts of climate change and experiences recurrent flooding, which affects large agricultural areas and poses a high risk to the population. The present study is focused on the recent flood disaster in the Ganga-Brahmaputra basin, which mainly affected the regions of Bihar, West Bengal, and Assam in India and neighboring Bangladesh during July, August, and September 2020. Using the Sentinel-1A Synthetic Aperture Radar (SAR) data, the flood extent was derived in the Google Earth Engine (GEE) platform. The composite area under flood inundation for July–September was estimated to be 25,889.1 km2 for Bangladesh, followed by Bihar (20,837 km2), West Bengal (17,307.1 km2), and Assam (13,460.1 km2). The Copernicus Global Land Cover dataset was used to extract the affected agricultural area and flood-affected settlement. Floods have caused adverse impacts on agricultural lands and settlements, affecting 23.68–28.47% and 5.66–9.15% of these areas, respectively. The Gridded Population of the World (GPW) population density and Global Human Settlement Layer (GHSL) population dataset were also employed to evaluate flood impacts, which revealed that 23.29 million of the population was affected by floods in the Ganga-Brahmaputra basin. The highest impacts of floods can be seen from the Bihar state, as people reside in the lower valley and near to the riverbank due to their dependency on river water. Similarly, the highest impact was from Bangladesh because of the high population density as well as the settlement density. The study provided a holistic spatial assessment of flood inundation in the region due to the combined impact of the Ganga-Brahmaputra River basin. The identification of highly flood-prone areas with an estimated impact on cropland and build-up will provide necessary information to decision-makers for flood risk reduction, mitigation activities, and management.

“…Effective implementation of adaptation measures against the impacts of climate variability and change requires farmers' knowledge and perceptions of the changes [ [22] , [23] , [24] , [25] , [26] ]. Furthermore, farmers' knowledge and perceptions of climate variability and change, and adaptation to its adverse impacts may differ depending on the local climate regime, the magnitude of impact the change, and other socioeconomic factors [ 27 ]. Previous assessments of climate variability, farmers' perceptions of the changes and adaptation strategies are usually carried out at country or regional scale in Ethiopia [ 28 , 29 ].…”
