Natural resources stewardship is necessary for maintaining the health of the environment: providing the basis for prudent long-term production systems and resource sustainability; minimizing direct costs to producers for maintaining environmental quality and indirect costs suffered by consumers when environ- mental quality is diminished; and ensuring high envi 17 ronmental quality, with its concomitant benefits for food, soil, and water.
Many budding researchers confuse a rationale with a hypothesis.
A hypothesis is what the researcher thinks is most likely to be proven through the research.
The statement of purpose is not simply a statement of why the research is being done. .: On another hand, some research reports end (or begin) with an abstract.
(That is what the rationale section is for.) Rather, "purpose" refers to the goal or objective of your research. An abstract is a highly abbreviated (usually100-200 words) synopsis of your research.
