The effects of China's Sloping Land Conversion Program on agricultural households

In the late 1990s, China aimed to mitigate environmental degradation from agricultural production activities by introducing the world's largest “Payments for Environmental Services? program: the Sloping Land Conversion Program (SLCP). We develop a microeconomic Agricultural Household Model, which can model the production, consumption, and nonfarm labor supply decisions of agricultural households in rural China in a theoretically consistent fashion. Based on this theoretical model, we derive an empirical specification, which we econometrically estimate using the Hausman–Taylor method and a large longitudinal farm household data set. The empirical results significantly differ between regions, but are generally consistent with the results of our theoretical comparative static analysis, for example, that the SLCP significantly decreases agricultural production. While the SLCP only increases nonfarm labor supply and total consumption in some regions, these effects could not be observed in others. The recent reduction of the SLCP compensation payment rates generally had negligible effects on agricultural production and off‐farm work and only very small effects on household consumption.     

Investigating the Impact of Income on Savings Using a Chinese Household Level Dataset

This article uses the China Household Financial Survey (CHFS) to examine the savings behavior of Chinese Households. Using a standard cross-sectional empirical approach to modeling permanent and transitory income, we show that one way of explaining the relative high savings rate in China is by recognizing that in fast growing economies, individuals may have higher transitory income from which they save a large proportion. The estimation also contains a range of household specific variables which can be used to understand the impact of socio-economic characteristics such as urban vs rural dwelling, age, and the educational level.     

农地流转对农户生计转型影响的实证分析

[目的]为清晰识别土地流转对农户生计转型的影响程度,以期为后期土地流转政策及农户生计引导政策提供科学的决策依据。[方法]文章借鉴已有研究方法,基于农户可持续生计分析框架,利用内蒙古4个市区的380户农户样本数据,采用Multinomial Logit模型对参与土地流转和未参与土地流转农户的生计模式进行了分析,客观评价农村土地流转对农户生计转型的影响。[结果]农地流转在一定程度上对农户的生计转型产生了显著影响,拥有较低自然资本和较高金融资本的农户倾向混合型和务工型生计策略,同时人力资本水平高的家庭更倾向于采取混合型生计策略,而不是采取农业型生计策略。[结论]农地流转后,农户从繁重的种植业活动中得以解放,有了更多时间和精力从事非农生产活动,生计策略由单一化走向多样化,从传统的主要依赖种植业到经营养殖业、从事建筑业、交通运输业、批发零售业等非农行业,多元化了农户的收入来源。     

Issues in measuring success in community-based Indigenous tourism: elites,kin groups,social capital,gender dynamics and income flows

Tourism development is a key feature of the neoliberal economic development model. Through a mix of state and private investment, Indigenous communities in Mexico are encouraged to transform local cultural and environmental resources into tourist consumption sites. The process results in a shift toward reliance on tourism, in place of farming, leaving households with few alternative earning strategies amidst fluctuating tourist arrivals and income, confounding the relationship between tourism and sustainability and questioning the utility of tourism as a sustainable tool for development. This article analyses a community-based Indigenous tourism project in a rural Maya village in Mexico's Yucatan, and discusses strategies employed at household level to navigate the arrival of tourism. Funding agencies assessed this project based on a triple bottom line metric that accounts for ecological health, financial sustainability, and its relationship to local social capital; however, these fail to account for differences between local and non-local conceptions of authenticity, indigeneity, and success. From a social perspective, the project has exacerbated existing tensions and has arguably widened the gap between the politically and economically powerful and less powerful, marginalized families in the community. Questions about policy, governance systems, and elite domination and kin group control are raised.     

Trade openness and household welfare within a country: A microeconomic analysis of Vietnamese households

The positive effects of trade liberalisation on several dimensions of poverty have initiated studies of the trade–poverty relationship. Trade liberalisation accompanies institutional reforms that help to reduce institutional barriers against the poor. This study examines the impacts of trade openness and institutional reforms on rural household welfare at the provincial level through the analysis of the determinants of welfare of rural households in Vietnam. The study employs a model of micro-determinants of growth and tests it on the data from the Vietnam Household Living Standards Surveys (VHLSSs) of 2006 and 2010. What makes the study different from some other studies of the same vein is that it attempts to directly capture the institutional effect on welfare. The study finds that, in the provinces with high institutional reforms and trade openness, the welfare of rural households improved. Institutional reforms in Vietnam appeared to be sluggish in the late 2000s. In particular, both access to land and lower informal charges were the important determinants of welfare improvement over time. These findings suggest that Vietnam should maintain its development by accelerating the process of institutional reforms, thereby helping poor households to improve standards of living.     

退耕还林背景下农户收入的社会网络效应分析 ——以四川南江县白滩村为例

研究目的:探讨退耕农户在生产力安排和收入结构方面是否存在同群效应或者互补效应,以及劳动力流动、退耕还林政策因素对农户收入结构的影响机制。研究方法:考虑农村社会网络内部农户间互动对其决策的影响,利用空间权重矩阵精确且全面地捕捉和定位社会网络复杂关系,构建空间计量模型展开分析。研究结果:(1)在白滩村社会网络体系中,农户的农业收入比增长1%,其亲戚邻居的家庭农业收入比降低6.7%,这一情况反映了劳动力由农业部门向非农部门转移而产生的社会网络"互补效应";(2)白滩村退耕程度越高的农户,其农业收入占家庭总收入比例就越高,退耕程度每增加1%,农业收入比将提高5.2%;(3)家庭总劳动力越多的,农业收入占总收入比例越低,其中家庭农业劳动力每流出1%,农业收入比减少3.2%。研究结论:(1)将白滩村社会网络的互补效应应用于其农村信息共享平台建设;(2)通过鼓励种植收入较高的经济林提高农民退耕还林积极性;(3)以就业为核心促进白滩村剩余劳动力转移。     

A Gendered Model of the Peasant Household: Time poverty and Farm Production in Rural Mozambique

Using insights from a case study on the allocation of labor in subsistence households in Mozambique, this study develops a conceptual framework for examining linkages between time poverty and farm production. An unexpected event such as a health crisis increases the demand for labor provided by women, thus making them more time poor. The model and numerical simulations show that a deterioration in a woman's time constraint will have an adverse effect on agricultural output of the household. This occurs because most women respond to an increase in household work by reducing their work hours on the farm and by reducing their leisure time. The latter outcome is expected to have a negative effect on women's physical and mental health, which will then cause a decline in their productivity on the farm.     

Sustainability of fish pond culture in rural farming systems of Central and Western Cameroon

In Sub-Saharan Africa, fish ponds are often an integral part of farming systems but have suffered from a lack of viability and sustainability. The present study aims to understand the strategies used by fish farmers to overcome economic and environmental constraints. In 2008 and 2009, fish farmers were surveyed in Central and Western Cameroon, and the fish production systems were classified by cluster analysis. Four broad types were identified according to the complexity of household operations. The development of extensive systems (large-scale and low-input) in rural areas of central Cameroon is induced mainly by abundant available land. For semi-intensive systems in both regions (small-scale and high-input in the Western Region, large-scale and high-input in peri-urban areas of the Central Region), horizontal integration is not sufficient to make fish production profitable and sustainable. More intensive fish farms tend towards vertical integration, in which farmers establish close links with input suppliers. Main causes of low productivity of semi-intensive systems (1–2?t/ha/yr) are both lack of knowledge of fish farming principles by farmers and lack of technical improvement by extension agents and researchers which need to consider the local complexity of farming systems to develop and intensify fish production. The adaptation of development strategies to socio-economic and environmental contexts is a necessity to hope for an increase in fish pond aquaculture production in Africa.
