Balancing ecological preservation with sustainable agricultural practices is a global issue. Erhai Lake has felt this challenge keenly. To address it, in 2022, a Science and Technology Backyards(STBs) project was launched in Gusheng Village. The goal of this is to care for the environment while ensuring that farms and farmers can thrive sustainably. The uniqueness of the Erhai STB arises from its interdisciplinary integration, encompassing fields such as ecology, agronomy and social science, resulting in specifically-designed solutions for the Erhai context. While this model aligns with broader STB paradigms, its distinctive edge lies in technological innovation and robust support mechanisms for local agricultural stakeholders. This paper describes the methodology and outcomes of the STB initiative, highlighting its pivotal role in spearheading sustainable transition in Erhai. Preliminary findings underscore the potential of the STB model as an efficacious tool for harmonizing environmental conservation and agricultural practices, that are both financially and environmentally sustainable, rendering it a potential model for comparable regions in China and other counties.

Globally,cocoa is famous for the production of chocolates and ***,it also serves as a source of raw material for the manufacturing of high-quality cosmetic and pharmaceutical products. Due to its high demand,cocoa is regarded as a major commodity for poverty alleviation in deprived cocoa farming communities. Government has therefore instigated relevant measures to address issues facing the sector by investing in extension programs. These programs act as information dissemination tools for teaching modern farming technologies and enhancing learning among farmers. This study highlighted the effects of the Cocoa Life Project (CLP) by Cooperative for Assistance and Relief Everywhere (CARE) International on farm productivity and income of 200 cocoa farmers in three districts of the Eastern Region,Ghana. Regression on covariates,Heckman’s treatment effects model,and propensity scores were used to test the robustness of the estimates. A positive association between extension program participation,farm productivity,and household income was discovered. Specifically,after correcting for selection bias,the estimated results of the Heckman’s model showed that the extension program significantly increased participating farmers’ cocoa yield by 14.3%. The effects on total farm income showed a significant increase of 25.1 and 42.9%,respectively from regression on propensity scores and the Heckman’s model. Across all three models,program participation led to an increase in total household income by 46.1,31.7,and 69.3%,respectively. Other variables such as farming characteristics,institutional and demographic factors affected farmers’ income,depending on the estimation method used. This study reiterated the supporting role played by extension programs in enhancing cocoa production and increasing household income in Ghana. Conclusively,government and development partners should invest in extension programs by providing enough logistics,training qualified agents,and creat

Oil palm is cultivated by agro-industries and smallholders for vegetable oil production. Good farm management practices with balanced soil and plant macronutrients are needed to attain optimum yields. Smallholder oil palm farmers of Dibombari Sub-Division, Cameroon, suffer from low on farm yields which could emanate from the agronomic practices implemented, which also has an influence on the soil and plant macronutrient status. This study provides information on the agronomic practices, soil and plant macronutrients status in smallholder oil palm fields. Structured questionnaires were administered to 200 farmers to collect data on their agronomic practices, using a stratified random sampling design. Soil and plants were sampled from plantations of different age groups (control, >0 - 4 years, >4 - 8 years and >8 - 15 years’ plantations) in four locations of the Sub-Division (i.e. Dibombari-central, Bonamateke, Bomono and Nkapa) using a randomized complete block design. Data collected, was analyzed using descriptive and inferential statistics. The results showed that 65% of farmers planted Tenera variety, with majority of them below the standards for weeding (81%), fertilizer use (100%), pruning (62%), pest/disease control (90.5%) and harvesting (96%) practices. Soil macronutrients were low across the different plantations except P which was optimal at >0 - 4 years and >4 - 8 years’ plantations but low at >8 - 15 years’ plantation. Similarly, for plant macronutrients, N and P were optimal across the different plantations, while K and Mg were optimal at >0 - 4 years’ plantation but low at >4 - 8 years and >8 - 15 years’ plantations. Thus, agronomic practices and macronutrient status of soil and plants were below standards in smallholder oil palm plantations of Dibombari, leading to low yields of fresh fruit bunches.

Transition to Certification Schemes and Implications for Market Access: GlobalGAP Perspectives in Kenya

引用

Agricultural Sciences 2014年第12期5卷 1100-1111页

作者： Isaac Maina Kariuki Department of Agricultural Economics and Business Management Egerton University Egerton Kenya

Voluntary pre-farm certification schemes especially GlobalGAP are increasingly defining market access for smallholders in developing countries. Their strict demand for financial and technical competencies and concerns for producer welfare and environmental conservation imply that transition to certified production could spell smallholders’ exit or shift to alternative markets for no-compliance. But what factors motivate successful transition to certification and does alternative market access exist for the unsuccessful transition? Multinomial logit estimates reveal training and higher farm assets base as key indicators of successful certification and organized production. However, a large cultivated land resource favours certification but disfavours transition to organized production. The results point to sensitivity of certification schemes to expertise on technical information and assets that enhance cultivation of quality, reliable and hygienic produce and economies of scale in farming. The transition to organized production seems efficient if technical knowledge and assets that enhance cultivation of quality, reliable and hygienic produce are present. The results imply that farmer expertise, farm assets and land resource are critical barriers for farmers transiting to certification schemes. This calls for concerted mitigation if smallholders in developing countries are to benefit from the lucrative premium markets in Western Europe.

Soil loss through erosion continues to pose serious challenges to increasing the smallholder agricultural productivity in Sierra Leone. While emphasis on sustainable land use practices continue to gain attention among land users, however, the rate of adoption among smallholder farmers is still very low and hence, in most part of the country soil fertility has been declining at alarming rates. In the Njala area, studies have shown that soil loss ranges from moderate to high. Though soil erosion has been identified as a major soil fertility declining factor, however, the effect of land use practices on the inherent resistance of soil materials to erosion is lacking. This study was therefore conducted to assess the effect of land uses on soil erodibility. The results showed that the soils are coarse sandy loam with high sand content. The dispersion ratios and erosion indices of soils under cassava, plantain, maize and guava were above the minimum thresholds of 15.0 and 10.0 respectively, thus indicating that these soils are highly erodible compared to soils under fallow and sweet potato which have dispersion ratios and erosion indices below the minimum thresholds. Clay content was inversely proportional to and significantly correlated with dispersion ratio and erosion index while the correlations between silt + clay, dispersion ration and erosion index, and silt, silt + clay and dispersion ratio were negative and non-significant. Considering the coarse nature of soils, landscape features and high erodibility indices, these soils would need special soil and water conservation practices to counter further degradation. These may include following, agroforestry, silvi-pasture, controlled and rotational grazing. In addition, awareness of sense of self-responsibility and forest policies and regulations are needed.

Coping with Shocks and Determinants among Indigenous Vegetable Smallholder Farmers in Kenya

引用

Agricultural Sciences 2018年第7期9卷 804-823页

作者： Evans Ngenoh Sindu W. Kebede Hillary K. Bett Wolfgang Bokelmann Department of Agricultural Economics Humboldt University of Berlin Berlin Germany Department of Agricultural Economics and Business Management Egerton University Nakuru Kenya

Farm households in developing countries are faced with various challenges one of which is occurrence of unexpected negative events namely shocks. Shocks could be caused by extreme adverse natural events (droughts, storms, flood, and landslides) and market-related events (fuel, food, input and output price fluctuations, volatilities and price hikes). Most of these shocks affect production systems, food markets and local economies, all of which have direct effects on food security. This study explores the prevalence of shocks among indigenous vegetable farmers in Kenya followed by an assessment of the type of coping strategies in response to these shocks. We find that over two thirds of farmers have coping strategies that are not based on market-related insurance mechanisms;rather they use strategies such as working for more hours and selling assets. We analyze which socioeconomic and institutional factors determine households’ decision and extent of coping with shocks. The results showed that access to high-value markets and market information were the major factors informing their decision and extent of using coping strategies along with access to critical services such as credit, extension, and farmer groups. This has significant policy implications regarding the dissemination of information and promotion of credit markets through mobile phone-based platforms for easy accessibility in remote rural areas. Social capital should be encouraged because it acts as a necessary and sufficient conduit for information dissemination and mutual support to help farmers’ access critical services and resources needed for successful and sustainable implementation of relevant and appropriate coping strategies.
