Crops are exposed to higher temperatures which many can endure. But it’s the increase in extremely hot days (and warm nights) that can cause the most damage. The threat of changing rainfall seasons leading to shifting rainfall dates plays havoc with planting dates and crop management.
How does rainfall affect plants?
This affects rainfall and seasonal patterns on a global scale.

Why do farmers use synthetic fertilizers?
Soil with a healthy texture is able to drain easily while still holding onto moisture, and it can also bind to nutrients to increase fertility. Weed control decreases soil organic matter, which results in poor fertility, which is why farmers have to use synthetic fertilizers.
How do weevils affect plants?
As the weevil infects one seed head, the insects start to reproduce and move on to the surrounding flowers. A lack of trees and native plants make it difficult for birds and beneficial insects to keep the population in check. Soon, an unstoppable swarm of weevils grows and moves across the field and decimates the crop.
Why are fields weed free?
Fields must be weed-free to prevent contamination in harvested crops and reduce water and nutrient competition. In nature, weeds don’t exist. Plants are intermingled, and each plant serves a purpose in the ecosystem. Some plants feed butterflies, bees, and hummingbirds.
What do plants feed?
Some plants feed butterflies, bees, and hummingbirds. Leafy plants feed grazing animals, while flowers and trees produce nuts and seeds for rodents. In commercial production, weeds compete with crops for water and nutrition, and some can get caught up in harvesting equipment and contaminate grain crops.
What are some examples of poor farming practices?
Examples include using excessive chemicals, over-tilling, and monocropping.
How does agriculture help the economy?
However, there is no consensus on the issue of whether agriculture is the most appropriate way to fight poverty in developing countries. One school of thought argues that since the majority of people in most developing countries are in rural areas and most of them are engaged in agricultural production or agriculture-related activities, agriculture is the most effective way to reduce poverty. The second school of thought recognises the contribution of agriculture to poverty alleviation but attaches more importance to non-agricultural activities (e.g. rural non-farm enterprises and social services). For example, McIntosh and Vaughan (1996:91) state that “… the notion that a broadly based smallholder agriculture can be created, and that it can transform the character of the agricultural production system is an inappropriate premise on which to build policy frameworks designed to improve livelihoods” in South Africa. Noting these divergent views on the role of smallholder agriculture in poverty alleviation, the following section outlines the positive contribution of agriculture, especially smallholder agriculture, to poverty alleviation.

Tracing The Problem
Within a year of the democratic government coming into power it had to accede to the World Trade Organisation(WTO). This meant that South Africa entered into an agreement that exposed its economy to global competition and had to play by global rules, both at home and internationally. Other agreements were signedwith the European Union (EU) and southern African countries. Some are still being negotiated. The direction taken by …
Two decisions – accession to the WTO and deregulation – put the sector in a very difficult position. In terms of job creation the sector has performed poorly. In addition, its contribution to GDPhas shrunk to less than 3% of GDP from 4.6% in 1994. Land redistribution has also not succeeded. Only 7.5%of he land targeted for black people has been tra…

Some Positive Outcomes
Despite the limited agricultural potential and resource scarcity, South Africa has managed to make substantial improvements in many areas. It remains one of the main exporters of agricultural products to the most lucrative markets in the developed world. It exports citrus, wool, avocados and nuts to the US and horticultural products, wine and tea to the EU. South Africa has also found new markets. Its biggest trading partners are now in Africa, …
Some of the contributors to the sector’s poor performance have been policy implementation and the panic these have caused among farmers.
