Land-evaluation part 2

Question 1

Geospatial ecosystem methodology

Answer 1

Based on standardized Terrestrial ecosystems
- sequenatial physical stratification of the earth in a set of unique physical environments with their associated biota

• The biodiversity that occurs any area is largely the result of a biotic response to the physical environmental potential and local dynamic processes.

unique environmental settings = unique assemblages of biodiversity

• land surface forms, surficial lithology, bioclimates, topographic moisture potential, associated land cover

Question 2

AEZ

Answer 2

agro-ecological zoning

ZONES
- on basis of soil, landform & climatic characteristics

• similar combinations of potentials & constraints
• Focus for recommendations (increasing production or reducing land degradation

Can be further used for land resource appraisal, natural resource analysis & land use planning if combined with other information

• knowledge current and future production potentials
• identification land water limitation
• insight current yields and production gaps + causes

Question 3

environmental aproach

Answer 3

• standardizerd framework that analysis synergies and frameworks
• alternative uses for agriculture for providing food and energy
• preservation of environmental equality
