What evidence exists for the effectiveness of on-farm conservation land management strategies for preserving ecosystem services in developing countries? A systematic map

Table 9 Overall outcomes on ecosystem service provision and yield, as reported by authors

Broad outcomes	ES improved	ES declined	ES mixed	ES same	Yield total
Yield improved	181	3	24	3	211
Yield declined	5	5	6	2	18
Yield mixed	27	2	39	1	69
Yield same	6	1	3	10	20
ES total	219	11	72	16	318

Table 9 shows the conclusions drawn by study authors, based on their results for yield and ecosystem services outcomes: 181 studies claimed on-farm conservation land management both improved ecosystem services and yield. This finding is a key topic for further exploration in a systematic review that includes statistical analysis (ES ecosystem service provision)
