Agriculture at a Crossroads: The Global Report by Science, and Technology International Assessment of

By Science, and Technology International Assessment of Agricultural Knowledge

The foreign evaluate of Agricultural wisdom, technology, and expertise for improvement (IAASTD) appears realistically at how lets successfully use agriculture/AKST to aid us meet improvement and sustainability pursuits. An unparalleled three-year collaborative attempt, the IAASTD concerned greater than four hundred authors in a hundred and ten international locations and value greater than $11 million. It file at the advances and setbacks of the prior fifty years and provides techniques for the following fifty years.
 
The result of the undertaking are contained in seven reviews: a world record, 5 neighborhood Sub-Global exams, and a Synthesis file. the worldwide document supplies the most important findings of the review, and the 5 Sub-Global exams deal with local demanding situations. The volumes current suggestions for motion. all the experiences were generally peer-reviewed by way of governments and specialists and all were authorized by way of a panel of engaging governments. The Sub-Global checks all make the most of an analogous and constant framework: studying and reporting at the affects of AKST on starvation, poverty, nutrients, human overall healthiness, and environmental/social sustainability. The 5 Sub-Global tests hide the subsequent regions:
 
Central and West Asia and North Africa (CWANA)
East and South Asia and the Pacific (ESAP)
Latin the US and the Caribbean (LAC)
North the United States and Europe (NAE)
Sub-Saharan Africa (SSA)

Sample text

Agriculture uses 85% of freshwater withdrawals in developing countries, mainly for use in irrigation, and water scarcity is becoming an acute problem, limiting the future expansion of irrigation (CA, 2007). Water conservation and harvesting also have an important potential for rainfed farming (Liniger and Critchley, 2007) as water scarcity is widespread. Climate change: Climate change influences and is influenced by agricultural systems. The impact of climate change on agriculture is due to changes in mean temperature and to seasonal variability and extreme events.

The different contexts have led to economic disparities within and among regions, countries and especially between industrial and small-scale farmers (FAO, 2000). Apart from differences in labor productivity, examples of disparities are average farm sizes (121 ha in North America vs. 6 ha in Asia and Africa, see von Braun, 2005; 100,000 ha in Russia, Ukraine and Kazakhstan, see Serova, 2007) and the crop yield gap between high- and low-income countries. The last 50 years have seen a tremendous increase in agricultural food production, at a rate more rapid than human population growth.

Additionally, AKST assessments are inherently inter- or multidisciplinary and generate knowledge through transdisciplinary approaches. Conditions determined by ecosystems, agricultural systems and production systems The concept of ecosystems provides a valuable framework for analyzing and acting on the linkages between people and the environment (MA, 2005a). An ecosystem is defined as a dynamic complex of plant, animal and microorganism communities and their nonliving environment, interacting as a functional unit (UN, 1992).
