greenhouse gas |
Greenhouse gases are those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of terrestrial radiation emitted by the Earth’s surface, the atmosphere itself, and by clouds. This property causes the greenhouse effect. Water vapour (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ozone (O3) are the primary greenhouse gases in the Earth’s atmosphere. Moreover, there are a number of entirely human-made greenhouse gases in the atmosphere, such as the halocarbons and other chlorine- and brominecontaining substances, dealt with under the Montreal Protocol. Beside CO2, N2O and CH4, the Kyoto Protocol deals with the greenhouse gases sulphur hexafluoride (SF6), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs).

malnutrition |
Malnutrition refers to deficiencies, excesses or imbalances in a person’s intake of energy and/or nutrients. The term malnutrition covers 2 broad groups of conditions. One is ‘undernutrition’—which includes stunting (low height for age), wasting (low weight for height), underweight (low weight for age) and micronutrient deficiencies or insufficiencies (a lack of important vitamins and minerals). The other is overweight, obesity and diet-related noncommunicable diseases (such as heart disease, stroke, diabetes and cancer).

for the purpose of the assessment, any action taken to address the threats, risks, distribution, abundance and impacts of an invasive alien species within a defined geographic area (Hulme, 2006; Pyšek et al., 2020). Management includes prevention, preparedness, eradication, containment, and control

management of wild species |
The management of wild species is the management process influencing interactions among and between wild species, its habitats and humans to achieve predefined impacts valued by stakeholders. It attempts to balance the needs of wild species and the preservation of the ecosystems they inhabit with the needs of humans, using the best available sources of knowledge.

Land having limitations which in aggregate are severe for sustained application of a given use. On these lands, options are limited for diversification without the use of inputs; inappropriate management of lands may cause irreversible degradation.

marginalization |
Marginalization refers to the set of processes through which some individuals and groups face systematic disadvantages in their interactions with dominant social, political and economic institutions. The disadvantages arise from class status, social group identity (kinship, ethnicity, caste and race), political affiliation, gender, age and disability.

marginalization |
Marginalisation is a complex and multidimensional concept, which simply cannot be seen as a state of being ( a condition of low income or food insecurity) but needs to be considered a process over time with several inter-related elements interacting with social and economic conditions, political standing, and environmental health. A full understanding of the term marginalisation needs to be based on the view that the best judge of poverty and marginalisation are the people experiencing it.

Marginalized communities, peoples or populations are groups and communities that experience discrimination and exclusion (social, political and economic) because of unequal power relationships across economic, political, social and cultural dimensions (National Collaborating Centre for Determinants of Health.

microevolution |
A change in gene frequency within a population. Evolution at this scale can be observed over short periods of time - for example, between one generation and the next, the frequency of a gene for pesticide resistance in a population of crop pests increases. Such a change might come about because natural selection favored the gene, because the population received new immigrants carrying the gene, because some nonresistant genes mutated to the resistant version, or because of random genetic drift from one generation to the next.
