What are the challenges of agro ecosystems in the world?

However, poor management practices in agroecosystems can also be the source of numerous disservices, including loss of wildlife habitat, nutrient runoff, sedimentation of waterways, greenhouse gas emissions, and pesticide poisoning of humans and non-target species.

Is agroecosystem affect the ecosystem itself why?

Intensification of agricultural practices causes the loss of biodiversity, and thus influence important ecosystem services. It affects plant production, plant protection, pollination, decomposition processes, nutrient cycles, and the resistance to invasive organisms [15, 63–65].

How does agriculture affect the ecosystem?

Agricultural practices have environmental impacts that affect a wide range of ecosystem services, including water quality, pollination, nutrient cycling, soil retention, carbon sequestration, and biodiversity conservation. In turn, ecosystem services affect agricultural productivity.

Which of the following is not a problem associated with agro ecosystem?

Answer: The correct answer of this question is option 4,increased dependence on few varieties of plants for food.

How does temperature affect the proliferation of insets in an agro ecosystem?

Warmer temperatures, changes in precipitation, increased drought frequency and higher CO2 concentrations due of climate change will have a devastating effect on abundance of insect pests, which might lead to the emergence of new pests.

What is meant by agro ecosystem?

An agroecosystem is the basic unit of study in agroecology, and is somewhat arbitrarily defined as a spatially and functionally coherent unit of agricultural activity, and includes the living and nonliving components involved in that unit as well as their interactions.

What is the importance of agrobiodiversity of agricultural ecosystem?

Agricultural biodiversity also performs ecosystem services such as soil and water conservation, maintenance of soil fertility and biota, and pollination, all of which are essential to human survival.

How do agriculture wastes harm the environment?

In many parts in developing countries, agricultural solid wastes are indiscriminately dumped or burnt in public places, thereby resulting in the generation of air pollution, soil contamination, a harmful gas, smoke and dust and the residue may be channeled into a water source thereby polluting the water and aquatic …

What is agro ecological system?

Agroecosystem. A simplified natural ecosystem subjected to exploitation for purposes of food and fiber production. Biodiversity. Diversity of microbial, animal, and plant species in an ecosystem that performs distinct ecological functions and services.

What is agro ecosystem management?

Agroecosystems management integrates economic, ecological and social values to tackle challenges and find opportunities. It takes a broad view that ranges from the ground under your feet to your neighboring farms and communities, and from farm to market to consumer.

What are the potential problems with agroecosystems?

In highly mechanized agroecosystems, the presence of combustion products from fossil fuels may also present problems. There are also specialized indoor environments that should be considered along with agroecosystems. These include such buildings as silos and livestock-rearing facilities, particularly those used for poultry or hogs.

How do managed agroecosystems differ from natural ecosystems?

In natural ecosystems there tend to be more niches and a higher diversity of species compared to most managed agroecosystems that are simpler, have fewer predatory and parasitic species, and less genetic diversity within a species.

Why are agricultural ecosystems more vulnerable to pest outbreaks than ecosystems?

Further, with low genetic diversity within agricultural species and across the landscape, the agricultural system is more vulnerable to pest outbreaks than natural ecosystems.

What is the role of Toxicology in the agroecosystem?

An item of particular importance to the role of toxicology in the agroecosystem is the regulation of the use of agrochemicals, particularly with respect to human health. In the USA, the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), administered by the US Environmental Protection Agency (EPA), is most important in this regard.
