The Sub-Global exams all make the most of an identical and constant framework: studying and reporting at the affects of AKST on starvation, poverty, foodstuff, human well-being, and environmental/social sustainability.

The last 50 years have seen a tremendous increase in agricultural food production, at a rate more rapid than human population growth. This was mainly due to the increase in area productivity, which differed between the regions of the world, while cereal-harvested area stagnated almost everywhere (Cassman, 2003). In all regions of the world, however, a decrease in the economic importance of the agricultural sector at different stages of economic development can be observed. But there is insufficient recognition of the fact that, in a monetized economy, the central functions of agriculture support the performance of other sectors.

Together these land cover areas provide about 93% of agricultural products. It should be noted, however, that other services provided by agroecosystems will have a considerably different balance. An example is forests, which provide clean water, reduce flooding, offer biodiversity protection and recreational and spiritual value, which adds to the importance of the forests’ production value. 1 Poverty and livelihoods Eradication of extreme poverty and hunger is a key goal of the assessment. Progress has been particularly striking in Asia, but the proportion of people in sub-Saharan Africa who live in extreme poverty has changed little since 1990.

Processes of water and wind erosion, and of physical, chemical and biological degradation are difficult to reverse and costly to control once they have progressed. The Global Assessment of Human-induced Soil Degradation (GLASOD) showed that soil degradation in one form or another occurs in virtually all countries of the world. About 2,000 million hectares are affected by soil degradation. , 1990). Water quality and quantity changes. Access to enough, safe and reliable water is crucial for food production and poverty reduction.
