“…An earlier study showed that waterlogging in maize at a different stage of growth affected not only the yield and yield components but also the plant growth, such as plant height, leaf area index, and plant dry matter [18]. Another study showed that rainfall variability during the growing season strongly affects maize yield [19]. The results of this study are also in agreement with the results of a previous study in the area that rainfall has a strong effect on maize yield [5].…”

The Covid-19 pandemic has had a broad impact on several aspects of human life, one of which is the issue of food sufficiency. Due to social restrictions, the agricultural sector, which plays a role in producing food for humans, may be affected by the pandemic. These restrictions impact the availability of farm labor and the market, both agricultural inputs, and outputs. This three-year study examines the factors that influence the productivity and income of maize farmers in the dry sandy lands of Gumantar village, North Lombok, Indonesia, before and during the Covid-19 pandemic. The method used was descriptive quantitative with 50 respondents, determined by accidental sampling. The study results showed variations in land area ownership of respondent farmers, variations in crop productivity, and variations in the form of products sold, such as selling cobs and selling grains. Maize production was more affected by rainfall, fertilizer availability, and pest disturbances than the Covid-19 pandemic. However, the Covid-19 pandemic impacted the income of maize farmers due to restrictions on the mobility of maize buyers.

“…Firstly, because of its capability to simulate simultaneously, the effect of climate, soil and management variables on crop growth processes and yield on a daily time step thus matching reality (Dimes et al, 2003;Carberry et al, 2004;Probert and Dimes, 2004;Makuvaro, 2014;Masere and Duffy, 2014). Secondly, APSIM has been validated in many farming systems of the world including Africa (Dimes et al, 2003;Carberry et al, 2004;Duffy and Masere, 2015). Thirdly, some of the participant Lower Gweru farmers had prior experience of interacting with APSIM and its outputs as they had already been introduced to APSIM including how it operates and its input data requirements (daily climate data, soil description data and crop management data) in an earlier study by Masere and Worth (2015).…”

The agriculture sector is sensitive to climate change and the capacity of smallholder farmers in developing countries to adapt is limited. Similar to adoption of any development-oriented strategies, perception is prerequisite to successful adaptation of agricultural strategies against climate change effects. This study was conducted in the semi-arid Lower Gweru Communal area of Central Zimbabwe to sensitize smallholder farmers on climate change and to establish their perceptions of the projected climate of Zimbabwe by 2050. Data were collected during 2011 from a total of 60 farmers drawn from six villages in Mdubiwa and Nyama Wards. Farmers were selected using systematic random sampling from a households list and grouped into three wealth groups: resource rich; resource poor and intermediate. Focus Group Discussions were conducted with each group to investigate their perceptions of the projected climate by 2050 and their proposed adaptive strategies. Farmers perceived the projected climate to have negative effects on their livelihoods and there were no outstanding differences in the nature of responses across the three categories of farmers. Farmers' responses showed that they were concerned about crop and livestock productivity as well as availability of water resources, food and nutrition security and about their general well-being. The intermediate wealth group, which had more than half of its members above 70 years of age provided the least number of ideas for adaptations. Farmers also suggested how they could possibly counteract some of the predicted negative effects or maximize on positive effects. Strategies that were suggested by the farmers were largely concerned with cropping and tended to address water shortages. It was concluded that almost all strategies suggested by farmers were self-directed, rather than directed at authorities like government or donors to do something for them thus showing that farmers had the will power to deal with climate change themselves.

“…Employing panel data from China's 2006-2015 National Rural Fixed-Point Survey, the results showed that both drought and rainstorm shocks had a negative effect on agricultural yield and income. Duffy and Masere (2015) utilized simulations to explore the impact of different withinseason daily rainfall distributions on potential maize yields. The findings indicate that these distributions can indeed influence maize yields during periods of low rainfall, with the use of fertilizer also playing a crucial role.…”

Agricultural production has clearly gained acceptance, as a crucial approach to meeting the food consumption needs of Nigeria’s growing population as well as an important requirement for achieving food security. Hence, the objective of this paper is to quantify the effect of change in rainfall dynamics on agricultural output in Nigeria employing a Dynamic Computable General Equilibrium model and using data from the 2019 Social Accounting Matrix. The results revealed that rainfall shocks had an adverse effect on the four components of agricultural output considered such as crops, livestock, fishery and forestry in the short and long term. It also had a negative effect on aggregate agricultural output compared to the baseline scenario. Therefore, public policy towards investing heavily in rain harvesters cannot be overemphasized. There is the need for policy efforts towards targeted interventions that provide an enabling environment and the necessary infrastructures for private investments in agriculture, address climatic risks and build resilience among farmers.
