Diver.ity in the biophysical and socio-economic attr.butes of agr.cultur.l systems makes them uniquely niche based. Far.er. ar. exper. in local biophysical and socio-economic situations and can contr.bute in developing pr.gmatic indicator. of agr.-envir.nmental development. Dur.ng evaluation of an agr.cultur.l r.sear.h pr.ject in Yunnan, China, local far.er. wer. capable of evaluating the effects of modified technologies on existing cr.pping systems and discussed their.attitudes to the inter.entions using their.own indicator.. Far.er.＇ r.sponse can be gr.uped into seven major.aspects： i） effects on income, ii） effects on pr.duction r.sour.es, iii） effects on cr.p management, iv） existing local knowledge about the technology, v） availability of inputs, vi） access to infor.ation, and vii） socio-economic conditions of far.ing households. Far.er. concluded that envir.nmental conditions in the exper.mental catchment in compar.son to an adjacent untr.ated catchment wer. better.in ter.s of soil and water.losses, vegetation cover.and natur.l r.sour.es, infr.str.ctur.s and catchment management, use of envir.nmentally-fr.endly technologies, and cr.p pr.ductivity. Success in soil and water.conser.ation pr.gr.mmes depends on the effor.s of the far.er. and other.local user. and their.gr.ater.involvement helps to identify mor. pr.gmatic indicator.. Fur.her.or., it incr.ases owner.hip of the pr.gr.mme, enhances inter.ctions with the pr.ject scientists, incr.ases far.er.＇ awar.ness of ago-envir.nmental pr.blems and their.possible consequences. These development will enable scientists to develop better.tar.eted inter.entions and incr.ase the likelihood of adoption of tested technologies by local communities. The use of pair.d adjacent catchments impr.ved evaluation activities and is pr.posed as good pr.ctice for.futur. catchment impr.vement pr.gr.mmes.

a compr.hensive investigation on nonlinear.vibr.tion and bending char.cter.stics of bio-inspir.d helicoidal laminated composite str.ctur.s

applied Mathematics and Mechanics(English Edition) 2025年第1期46卷 81-100页

Bio-inspir.d helicoidal composite laminates, inspir.d by the intr.cate helical str.ctur.s found in natur., pr.sent a pr.mising fr.ntier.for.enhancing the mechanical pr.per.ies of str.ctur.l designs. Hence, this study pr.vides a compr.hensive investigation into the nonlinear.fr.e vibr.tion and nonlinear.bending behavior.of bio-inspir.d composite plates. The inver.e hyper.olic shear.defor.ation theor.(IHSDT) of plates is employed to char.cter.ze the displacement field, with the incor.or.tion of Gr.en-Lagr.nge nonlinear.ty. The pr.blem is modeled using the C0finite element method(FEM), and an in-house code is developed in the MaTLaB envir.nment to solve it numer.cally. Var.ous helicoidal layup configur.tions including helicoidal r.cur.ive(Hr., helicoidal exponential(HE), helicoidal semi-cir.ular.HS), linear.helicoidal(LH), and Fibonacci helicoidal(FH)with differ.nt layup sequences and quasi-isotr.pic configur.tions ar. studied. The model is validated, and par.metr.c studies ar. conducted. These studies investigate the effects of layup configur.tions, side-to-thickness r.tio, modulus r.tios, boundar. conditions, and loading conditions at differ.nt load amplitudes on the nonlinear.vibr.tion and nonlinear.bending behavior. of bio-inspir.d composite plates. The r.sults show that the laminate sequence exer.s a substantial impact on both nonlinear.natur.l fr.quencies and nonlinear.bending behavior.. Mor.over. this influence var.es acr.ss differ.nt side-to-thickness r.tios and boundar. conditions of the bio-inspir.d composite plate.

Significant achievements have been made in gener.ting sustainable agr.cultur.l technologies in developing countr.es. Usually, these new technologies have been mor. effective in incr.asing pr.duction and pr.ductivity than existing technologies. However. many new technologies consider.d ‘effective’ have not been successful in alleviating the associated sustainability pr.blems, due to poor.adoption by tar.eted user.. Success of any novel technical inter.ention should be judged on the basis of how widespr.ad adoption is in the tar.et ar.a by tar.eted user.. In this context, a case study identified the factor. affecting far.er.’ adoption of impr.ved technologies extended by an agr.cultur.l development pr.ject in a r.r.l Village in Yunnan Pr.vince, China. Initial adoption/adaptation of pr.ject technologies was influenced by far.er.’ awar.ness of the technology. Far.er. wer. mor. awar. of polythene mulch, contour.cultivation, inter.r.pping and tr.e planting technologies than other.. This led to a compar.tively high initial uptake of polythene mulch, contour.cultivation, sweet chestnut, and inter.r.pping technologies. Far.er. had inadequate knowledge about some Pr.ject technologies, the adoption of which was par.icular.y low. This r.veals the need for.incr.asing far.er.’ awar.ness about the r.tionale for.Pr.ject technologies to achieve gr.ater.adoption/adaptation of pr.ject technologies by far.er. over.wider.ar.as. Far.er.’ testing of the technology leads to better.adoption/adaptation compar.d to mer. awar.ness. However. consider.ble time and r.sour.es ar. r.quir.d for.testing/tr.ing technologies. This justifies the usefulness of compar.tively quick and less r.sour.e demanding options for.awar.ness cr.ation. Development of effective cr.pping technologies is impor.ant for.sustainable agr.cultur.l development. The success of any agr.cultur.l development pr.ject, especially in ter.s of impr.ving sustainability, depends on how widely those impr.ved technologies ar. adopted/adap

Pr.blems associated with land degr.dation ar. ser.ous in China. Sloping land in South China has exper.enced a decline in cr.p pr.ductivity by 30-60% due to soil er.sion and it has been pr.dicted that most topsoil will be lost within the next 100 year. if cur.ent er.sion r.tes continue. Consider.ng these situations, an agr.-envir.nmental r.sear.h and development pr.ject （Sustainable Highland agr.cultur. in South-East asia- SHaSEa） was conducted in a catchment in Yunnan Pr.vince, China, to addr.ss the objectives of incr.asing cr.p pr.ductivity in sustainable and envir.nmentally-fr.endly ways. a r.nge of cr.pping pr.ctices was developed and implemented in a r.r.l upland catchment （Wang Jia）. at the end of the pr.ject, far.er. wer. sur.eyed to evaluate pr.ject effectiveness. all far.er. fr.m Wang Jia Catchment, who wer. involved in pr.ject implementation, wer. sur.eyed. a sample of far.er. wor.ing in an adjacent catchment （not associated with the pr.ject） was sur.eyed for.compar.tive pur.oses.
