Environmental impact of irrigation. The first environmental effect is increased crop growth, such as in the Rubaksa gardens in Ethiopia. The irrigation that grows crops, especially in dry countries, can also be responsible for taxing aquifers beyond their capacities. Groundwater depletion is embedded in the international food trade, with ...
Society portal. v. t. e. Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments [ 1 ] and to ecosystems, biodiversity, and natural resources [ 2 ] caused directly or indirectly by humans. Modifying the environment to fit the needs of society (as in the built environment) is causing ...
Relocating current croplands to environmentally more optimal locations, whilst allowing ecosystems in then-abandoned areas to regenerate could substantially decrease the current carbon, biodiversity, and irrigation water footprint of global crop production, with relocation only within national borders also having substantial potential.

Human impact on river systems. Many river systems are shaped by human activity and through anthropogenic forces. [1] The process of human influence on nature, including rivers, is stated with the beginning of the Anthropocene, which has replaced the Holocene. [citation needed] This long-term impact is analyzed and explained by a wide range of ...
Water conservation aims to sustainably manage the natural resource of fresh water, protect the hydrosphere, and meet current and future human demand. Water conservation makes it possible to avoid water scarcity. It covers all the policies, strategies and activities to reach these aims. Population, household size and growth and affluence all ...
Biodiversity (or biological diversity) is the variety and variability of life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and phylogenetic diversity. [ 1 ] Diversity is not distributed evenly on Earth.
Using water for domestic, food and industrial uses has major impacts on ecosystems in many parts of the world. This can apply even to regions not considered "water scarce". [3] Water scarcity damages the environment in many ways. These include adverse effects on lakes, rivers, ponds, wetlands and other fresh water resources.
No one factor operates in isolation and components of the ecosystem respond differently to each individual factor. The traditional approach to fisheries science and management has been to focus on a single species. This can be contrasted with the ecosystem-based approach. Ecosystem-based fishery concepts have been implemented in some regions. [42]
