Document Summary
Highlight=things i found especially useful when studying. How do we know if a system is moving towards sustainability: how things are changing over time, e. g. yields, the process. Societal goals and objectives>>actions (policies, adoption of farming systems or practices)>>monitoring (indicators)>>evaluation>> societal goals and objectives: hard to come up with measures, environmentally relevant options are usually less feasible. !1: pollination services worth around billion annually. Socioeconomic indicators: farm income/pro tability, transience, quality of life indicators. Pro t margins by farm size: big farms are making the pro ts. Much harder for small and medium farms. 88% of the farms only account for 14% of the value. Issues of spatial and temporal scale: eld, farm, watershed, region, country, world, hours, days, storm events, seasons, years, rotation cycles, decades. For example- nutrient pollution and water quality impacts. Nutrients in waterways is a national priority. Do farmworkers receive adequate income to meet the basics: watershed/rural community.
