“…Agricultural production generally depends on favorable weather conditions [19], which determine the types of crops cultivated in different regions, overall productivity, and farmers' livelihood [20]. Global increases in temperature and recurrent climate hazards like droughts, floods, and wildfires [3,21,22] threaten agricultural sustainability [23][24][25][26][27] and the livelihood of farmers [28][29][30].…”

Climate Change and Small Farmers’ Vulnerability to Food Insecurity in Cameroon

There is interconnectedness between small farmers’ productivity, climate change, and the state of food security in Africa south of the Sahara. The neglect of small farmers amidst climate change challenges in the Global South suggests the existence of a vicious circle of low productivity and deprivation that exacerbates the vulnerability of small-scale farmers, who largely depend on rain-fed agriculture to feed their families and nations. The limited adaptive capacity of these farmers in the face of growing instability in rainfall and temperatures is affecting the output, profitability, and survival of these small-scale farmers, whose production is principally for the local market and therefore critical for community food security. The underdeveloped local agricultural sector and limited investment in climate-smart agriculture also affect small farmers’ productivity and ability to meet the food demands of increasing populations. This paper examines the challenges of small-scale farmers in a resource-rich economy, their vulnerability to climate change, and the effects on food insecurity. It is based on an in-depth qualitative case study of 30 residents from the Tiko and Santa areas in the South West and North West regions of Cameroon, respectively. The paper argues that small farmers’ vulnerability to climate-induced agricultural losses increases the risks of food insecurity for the growing Cameroonian population.

Similar model was used by Nastis et al (2012) to analysis the climatic impact on agricultural productivity in Greek. Gupta et al (2012) employed a Cobb-Douglas production function model to investigate the effect of climatic and non-climatic factors on rice, sorghum and millet productivity utilizing panel in India.…”

This study provides an understanding for the relationship between climatic factors and sugarcane productivity in India. The main objective of this paper is to estimates the impact of climatic and non-climatic factors on sugarcane productivity. To check the consistency of empirical results, simple linear regression model, Ricardian productivity regression (non-linear) model and Cobb-Douglas production function models are employed. The data set incorporates 390 observations corresponding to thirteen states with panel data for 30 years during 1980 to 2009. These all models include sugarcane productivity as dependent variable. Irrigated area, agriculture labour, consumption of fertilizers, literacy rate, tractors and farm harvest price (at constant level) are considered as explanatory variables. Average rainfall, average maximum and average minimum temperature include as climatic factors to capture the effect of climatic conditions on cane productivity. These climatic factors are incorporate for three weather seasons such as rainy, winter and summer. Empirical results based on Prais Winsten models with panels corrected standard errors (PCSEs) estimation shows that climatic factors i.e. actual rainfall, average maximum and average minimum temperature have a statistically significant impact on sugarcane productivity. The climatic effect for various factors on cane productivity are varies within different seasons. Average maximum temperature in summer and average minimum temperature in rainy season have a negative and statistically significant effect on sugarcane productivity. While, sugarcane productivity positively get affect with increasing average maximum temperature in rainy season and winter seasons. The study concluded that there is non-linear relationship between climatic factors and sugarcane productivity in India.

“…The world population is expected to increase from 7.7 billion people in 2020 to about 9.7 billion people by 2050 [1]. As a result, the global food demand is expected to double by the 2050s [2,3]. Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years [2].…”

“…The production of crops in the future will be stressful, as climate change is expected to impact crop yields negatively. The climate attributes expected to have the most direct impacts on agricultural productivity are the rise in temperature, the change in the frequency and intensity of precipitation and extreme weather phenomena, and the increase in the level of CO 2 available for photosynthesis [3]. Many countries in tropical and sub-tropical regions are expected to be more vulnerable to climate change, which will affect their marginal water balance and harm their agricultural sectors [4].…”

Study on the Growth Performance of Lettuce (Lactuca sativa) and Pak Choi (Brassica chinensis) in Different Aquaponic Growing Systems

Aquaponics is a human-made recirculating ecosystem that integrates the cultivation of crops and aquaculture to produce higher-quality, safe, and nutritious food. However, limited studies have been conducted to investigate the performance of different aquaponic plant growing systems. As such, the current research focuses on evaluating the overall performance of four different aquaponic growing systems in the growth and yield of lettuce and pak choi. The data on the shoot and root biomass and growth parameters were collected, and the growth analysis was performed. The relative growth rate results indicated that the appropriate environmental conditions were provided for lettuce and pak choi to grow successfully in all the four aquaponic growing systems. The crop growth rate results revealed that all four aquaponic growing systems tested in this experiment were able to grow crops and provide yield successfully. However, the substrate-based closed capillary water distribution system (CCWD) had the best overall result, which showed great potential for aquaponic applications to promote alternative agriculture production under unfavored climate conditions.
