“…Digging up a deep well appears to be challenging to them and not rewarding. The adaptation strategies practiced by smallholder farmers in the study area are more or less similar to those reported by several authors which were adopted by people for the sustainable production of various crops in different areas (e.g., Challinor et al 2014;Kifunda 2014;Lipper et al 2014;Malhi et al 2021;Koné and Galiegue 2023). Altering amounts and timing of irrigation and other water management practices like drip irrigation have been suggested to be good adaptation strategies for smallholder farmers (Ndamani and Watanabe 2015;Ogundeji 2022).…”

“…The results are supported by the study conducted in Dodoma City by Namwata et al (2015), who reported that access to quality water is expensive and therefore unaffordable by many farmers. Other studies, such as the research of Koné and Galiegue (2023), have recommended the combination of improved seed varieties, soil and water conservation practices, and the application of Biochar as one of the best innovations to adapt to climate change in agriculture.…”

Abstract. Kifunda CF. 2023. Effects of climate change and adaptation strategies on urban crop production in Kinondoni City, Tanzania. Asian J Agric 7: 98-107. Many countries worldwide, including Tanzania, have felt the effects of climate change on the productivity of major economic sectors, such as agriculture. This study assessed climate change's effects on urban agriculture's sustainability in Kinondoni City, Tanzania. Specifically, the study aimed to determine: i) the effects of climate change on crop production in Kinondoni City over the last 30 years, ii) other challenges of urban agriculture in Kinondoni City, and iii) adaptation strategies employed by smallholder farmers in sustainable urban agriculture in Kinondoni City. Data collection involves accessing temperature and rainfall data from Tanzania Meteorological Agency (TMA) headquarters and administering household questionnaires to 386 respondents who engaged in urban agriculture in Kinondoni City. Five wards of Bunju (118), Kunduchi (42), Mabwepande (102), Mzimuni (28) and Wazo (96) were involved. Focused group discussion, key informant interviews, and direct observation were also employed. Data were analyzed for temperature and rainfall variations over the last 30 years and people's knowledge of climate change indicators. The adaptation strategies employed in sustaining crop production in the study area were also quantified. The study reveals that most smallholder farmers (>70%) are aware of the indicators of climate change, which correlate with the data obtained from TMA. Among the indicators include an increase in temperature (76%) and a decrease in rainfall (73%). Pest and diseases were ranked higher (88%) among the significant effects of climate change on urban agriculture. Land scarcity was also a significant challenge in urban agriculture. The use of pesticides and fertilizers was ranked higher (65%) among the adaptation strategies employed by smallholder farmers. It is recommended that building capacity for smallholder farmers through getting access to micro-credits at low-interest rates and government support may contribute significantly to sustainable urban agriculture in Kinondoni City. Also, farmers in Kinondoni City can adopt sustainable agriculture practices such as Soil and Water Conservation practices and the use of Drought-Resistant Crop varieties to improve their resilience to future climate risks caused by climate change.

“…Despite these changes, the pH of the soil, phosphorus availability, and effective cation CEC remained unaffected for both forms of biochar, with the rice-husk biochar demonstrating nitrogen (N) retention. Studies conducted by Koné and Galiegue [164] in Senegal, Cornelissen et al [165] in Zambia, Kimetu et al [37], and Mahmoud et al [166] in Kenya also documented positive outcomes associated with biochar application on crops, mirroring the findings observed in Nigeria.…”

“…There are certain difficulties with biochar that need to be resolved. When biochar is mixed into soils or later eroded, tiny particles of biochar that are discharged into the air can potentially cause considerable regional and global warming [164]. Black carbon, present in charcoal, is one of the biggest contributors to global warming.…”

“…These stand to be a major problem during pyrolysis, particularly if the biomass has undergone chemical treatment, includes other pollutants, or is combined with municipal solid waste, used tires, and other garbage. Additionally, a study found that when applied, 30% of the biochar escaped into the atmosphere [164]. The dust produced by the ashes of rice husks has been linked to silicosis, a lung condition that often proves fatal and has irreversible and increasing effects [195].…”

Africa, specifically Nigeria, has witnessed a dramatic increase in population over the last century, prompting efforts to ensure sustainable food production and quality. Concerns for soil sustainability and food security have led to the exploration of cost-effective methods, such as biochar, to enhance soil quality. Researchers in Nigeria and Africa as a whole have investigated biochar’s potential to improve soil fertility and crop performance across various agroecological zones. This paper aims to review recent biochar research priorities on soil fertility and crop performance with an emphasis on various sole biochar applications and combinations with fertilizers to determine the research gaps that need to be developed more in biochar research in Nigeria. From the papers reviewed, sole biochar applications and biochar + macronutrients and biochar + manure combinations were studied more dominantly, while biochar + micronutrients research projects were scanty despite their low content in the semi-arid soils of Nigeria. The studies were spread across the country with the majority taking place in derived savanna and humid forest, while Sudan savanna and Sahel savanna received less research attention despite being characterized by a low-fertile soil and vast area of land. Research involving BC in the context of Sahel savanna (SLS) and Sudan savanna (SS) soils is strongly encouraged in Nigeria. This research should encompass a wide range of investigations, including sole BC applications and combinations of BC with macronutrients, micronutrients, and manure, as well as exploring its potential as a slow-release fertilizer. Incorporating exclusive biochar in substantial amounts appears economically unfeasible within the context of local biochar production. However, it can be utilized in the synthesis of slow-release fertilizers, requiring smaller quantities and potentially offering cost-effectiveness. This approach enhances soil condition and crop productivity. Challenges are faced due to less commercial production as a result of inadequate power and structural facilities. Exploring the modification of local biochar for slow-release fertilizers through future research offers potential profitability.
