  abstract = {{O}rganic matter management is key to sustain ecosystem services provided by soils. {H}owever, it is rarely considered in a holistic view, considering local resources, agro-environmental effects and harmonization with farmers' needs. {O}rganic inputs, like compost and biochar, could represent a sustainable solution to massive current challenges associated to the intensification of agriculture, in particular for tropical regions. {H}ere we assess the potential of agricultural residues as a resource for farmer communities in southwestern {I}ndia to reduce their dependency on external inputs and sustain ecosystem services. {W}e propose a novel joint evaluation of farmers' aspirations together with agro-environmental effects of organic inputs on soils. {O}ur soil quality evaluation showed that biochar alone or with compost did not improve unilaterally soils in the tropics ({A}nthroposol, {F}erralsol and {V}ertisol). {M}any organic inputs led to an initial decrease in water-holding capacities of control soils (-27.3%: coconut shell biochar with compost on {A}nthroposol). {R}esponses to organic matter inputs for carbon were strongest for {F}erralsols (+33.4% with rice husk biochar), and mostly positive for {A}nthroposols and {V}ertisols (+12.5% to +13.8% respectively). {S}oil p{H} responses were surprisingly negative for {F}erralsols and only positive if biochar was applied alone (between -5.6% to +1.9%). {F}or {A}nthroposols and {V}ertisols, highest increases were achieved with rice husk biochar + vermicomposts (+7.2% and +5.2% respectively). {O}ur socio-economic evaluation showed that farmers with a stronger economical position showed greater interest towards technology like biochar (factor 1.3 to 1.6 higher for farmers cultivating {A}nthroposols and/or {V}ertisols compared to {F}erralsols), while poorer farmers more skepticism, which may lead to an increased economical gap within rural communities if technologies are not implemented with long-term guidance. {T}hese results advocate for an interdisciplinary evaluation of agricultural technology prior to its implementation as a development tool in the field.},
