Mar 15, 2022 · There is considerable pressure on agriculture to meet the demands of a growing world population. This is heightened with rising demand for necessities such as food, raw materials for industries, and biofuels. However, growth in agricultural production globally does not match this demand well, especially in parts of Africa.

- Food production has a large environmental impact in several ways. What are the environmental impacts of food and agriculture? The visualization here shows a summary of some of the main global impacts
- Half of the world’s habitable land is used for agriculture. Around half of the world’s habitable land is used for agriculture. Habitable land is land that is ice- and desert-free.
- Food is responsible for one-quarter of the world’s emissions. Food systems are responsible for around one-quarter (26%) of global greenhouse gas emissions.8.
- Emissions from food alone would take us past 1.5°C or 2°C this century. One-quarter to one-third of global greenhouse gas emissions come from our food systems.
Feb 17, 2022 · Our primary aim is to provide descriptive insights into how the COVID-19 pandemic affects agricultural households. We refrain from generalising these results for the entire population and for all agricultural households due to selection and non-response biases associated with phone surveys.

At the regional level, the Southern and Western regions have the most substantial reductions in rainfall averaging between 3 and 4 percentage points with an interquartile range of 8 (Figs. 1 and S1). This suggests that the Southern and Western regions of Zambia are the most vulnerable to climate change and will likely experience more reduced rainfa...
Temperature is projected to be around 1.8 °C higher by 2046–2050 across all regions under the UCE scenario, although temperature increases could be as large as 3.6 °C (Fig. 2 and Table S1). Notably, all regions are expected to experience temperature increases of above the often used 1.5 °C threshold (Fig. 2, right panel).Footnote 10
The average annual yield deviations are between the baseline scenario where there is no climate change and each of the 421 and 398 different climate scenarios under UCE and L1S, respectively, for the period 2046 to 2050. According to the 2007 SAM for Zambia, the focal crops—maize, cotton, tobacco, root crops, and other cereals—account for just over...
Table 4 presents results on the impacts of climate change on production for specific crops and by region. These results highlight two main nuances. These impacts are measured as the ratio relative to the baseline scenario. As such, a value > 1 implies an increase relative to the baseline scenario without climate change, and a value of < 1 implies t...
The impacts of climate change on the general economy by decade under UCE are presented in Fig. 5. While climate change is projected to reduce GDP throughout the 4 decades, the negative impacts are progressive with time as is the uncertainty of these impacts (Fig. 5). For example, the impact of climate change on GDP in the first decade deviates only...
We use household expenditure as a measure of household welfare. Figure 6presents results by region and expenditure quintiles for rural households. The main finding is that climate change is projected to have larger negative effects on household expenditure for rural households in Southern and Western regions across all quintiles during the 2046–205...
The foregoing results show the potential impacts of climate change on the Zambian economy under the UCE scenario. When compared to results under the L1S scenario, the UCE scenario paints a more negative picture for Zambia with higher levels of uncertainty (see Fig. 7). For example, the impacts of climate change on maize production are less uncertai...

Apr 17, 2021 · Sustainable agriculture is an important aspect of the food system that plays a vital role in enhancing farm incomes and household food security, especially in developing countries (Zero Hunger Challenge, 2016). Achieving sustainable household food production in Africa is however beset with numerous challenges.

Apr 29, 2024 · Climate change reduces agricultural productivity and leads to greater instability in crop production, disrupting the global food supply and resulting in food and nutritional insecurity.
Mar 14, 2021 · Sustainable agriculture has been recognized in the literature as one of the important pathways to ensuring food systems and livelihoods among rural households in Africa.
