Agricultural Practices and Challenges

Natural habitats are transformed into agricultural land, decreasing biodiversity.
Deforestation involves cutting down forests for lumber, often for profit through trade.
Cleared land is used for farmland or settlements.
Less economically developed countries are more likely to destroy natural resources for economic gain.
More economically developed countries protect resources and engage in trade.
Deforestation occurs in slash-and-burn agriculture, where rainforest is cut and burned for crops.
Slash and burn increases CO_2 in the atmosphere and destroys ecosystems.

Excessive irrigation can lead to soil salinization.
Soil salinization is the accumulation of salt in the soil, harming plant roots.
Affected land becomes unsuitable for agriculture, leading to soil erosion, degradation, and desertification.
Pastoral nomads in the Middle East and Africa contribute to desertification through overgrazing.

Post-Green Revolution, there's increased use of GMOs, antibiotics, chemical fertilizers, pesticides, and herbicides.
Benefits include faster crop/livestock growth, higher yields, and increased profits.
Concerns arise over the impact on food and unintended consequences.
Modern agriculture unsustainably uses water, depleting aquifers.
Chemical fertilizers and pesticides cause soil degradation and pollute waterways.
Industrialized farms and feedlots have led to economies of scale, increasing inequalities and disadvantaging small family farms.
Livestock animals are often injected with hormones and antibiotics and raised in confined spaces, reducing the environment's resilience to climate change.

Inadequate infrastructure causes unequal access to fresh food globally.
Economically developing countries lack fresh food and a dependable food supply.
Global conflicts and natural disasters exacerbate food supply issues.
Food deserts exist in developed countries like the U.S., where people lack access to healthy foods, leading to higher rates of diabetes and obesity.
Urban sprawl replaces arable land with concrete.
Agricultural subsidies (government payments to farmers) influence farm operations and production.
Regions with pro-farm policies and subsidies may see increased production, while those with stricter regulations may see fewer farms.

Community-supported agriculture (CSA) involves local farmers selling directly to consumers, reducing risk and food miles.
Food miles refers to the distance food travels from production to consumption.
Urban farming includes small-scale farms in urban areas (backyards, rooftops, community gardens), providing fresh food, combating food deserts, creating green spaces, and offering recreation.
Organic farming uses natural methods without chemical fertilizers, pesticides, or GMOs, reducing pollution.
Fair trade practices enable consumers to buy directly from producers, who receive a larger portion of the profit and have better working conditions.

Value-added crops are processed agricultural products with increased value such as jams, cereals, juices.
Production involves packaging, branding, and adding preservatives.

In economically advanced countries, women have more opportunities.
In less economically developed regions, traditional gender roles persist, keeping women in the informal economy.
The informal economy involves unregulated jobs.
Agriculture is central in less economically developed regions, but women's participation varies.
Women may have limited access to resources and face cultural restrictions.
They may be limited to subsistence farming.
Women in less economically developed areas often lack nutritious food and may suffer from malnourishment due to poverty and limited education.
As countries advance, women gain political and social opportunities, participate more in the formal economy, benefit from legal protections, and have increased land ownership rights.
Increased women's participation leads to higher economic growth and a higher standard of living.
