Chinese Forest Policy Reforms After 1998: The Case of the Natural Forest Protection Program and the Slope Land Conversion Program

Journal Articles & Books
Décembre, 2013
Chine

SUMMARYIn this article we discuss the two largest reforestation and forest conservation programmes in China, the Natural Forest Protection Programme (NFPP), and the Slope Land Conversion Programme (SLCP, also called Grain for Green), introduced in 1998. The NFPP reformed the state forest enterprises to reduce deforestation, increase the amount of forestland to be protected, and increase the sustainability of logging, while improving their financial viability. The SLCP reformed collective (i.e.

Soil organic matter of Iberian open woodland rangelands as influenced by vegetation cover and land management

Journal Articles & Books
Décembre, 2013

Spanish rangelands occupy more than 90,000km² of land grazed by millions of domestic and wild animals. Organic matter content of soil is an essential component for fertility and productivity in both, natural and human-induced ecosystems. Despite its importance to soil quality, soil organic carbon has been little studied in these rangelands. The main goal of this study is to assess the amounts and characteristics of soil organic matter in grazed open woodlands of SW Iberia as influenced by vegetation cover and land management.

Exploring the links between local management and conservation applying the ecosystem services concept: conservation and tourism service in Camargue, France

France

This article aims at testing whether the ecosystem services framework helps in understanding the link between local management and biodiversity conservation. Tourism was analysed in Camargue (France), a wetland area of high biodiversity value, via semi-structured interviews with local stakeholders. Three types of stakeholders were interviewed: protected area managers, livestock farmers and public institutions. This was done to examine whether they manage the land to enable tourism and/or maintain or restore the ecological state of ecosystems.

Prospects for arable farm uptake of Short Rotation Coppice willow and miscanthus in England

Journal Articles & Books
Décembre, 2013

Biomass will play a role in the UK meeting EU targets on renewable energy use. Short Rotation Coppice (SRC) and miscanthus are potential biomass feedstocks; however, supply will rely on farmer willingness to grow these crops. Despite attractive crop establishment grants for dedicated energy crops (DECs) in the UK, uptake remains low. Drawing on results from an on-farm survey with 244 English arable farmers, 81.6% (87.7%) of farmers would not consider growing miscanthus (SRC), while respectively, 17.2% (11.9%) would consider growing and 1.2% (0.4%) were currently growing these crops.

Collective management on communal grazing lands: Its impact on vegetation attributes and soil erosion in the upper Blue Nile basin, northwestern Ethiopia

Éthiopie

Collective action, on communal grazing land, has evolved in the highlands of northwestern Ethiopia to mitigate the problems of feed shortage and land degradation due to overgrazing. The exercise is liked by farmers for improving the availability of natural pasture during the long dry season when other feed sources get depleted. However, large portions of the communal grazing lands are still managed under free grazing throughout the year.

By the year 2050, agriculture will have to provide the food and nutrition requirements of some 9 billion people. Moreover, to maintain that level of productivity indefinitely it must do so using environmentally sustainable production systems. This task will be profoundly complicated by the effects of climate change, increasing competition for water resources and loss of productive lands.

Exploring double side-selling in cooperatives, case study of four coffee cooperatives in Rwanda

Rwanda

Apart from the difficulty to attract new members, leakage of sales outside the cooperative is a major challenge for the coffee cooperatives in Rwanda. Local (independent) traders still constitute a major market for coffee producers. Yet, cooperatives also accept the produce from non-members and pay them the same price. Our objective in this paper is to analyse the importance of this phenomenon of double side-selling. We collected data from a sample of 170 coffee farmers. We use a probit model to analyse characteristics linked to cooperative membership and to study double side-selling.

Carbon blinkers and policy blindness: The difficulties of ‘Growing Our Woodland in Wales’

Journal Articles & Books
Décembre, 2013

The need for climate change mitigation has led to a recent upsurge in policies aimed to deliver re-afforestation across the globe, but with mixed successes observed depending upon the levels of private land ownership and ability of governments to engage land managers. This paper evaluates a new government-led scheme in Wales, which is intended to increase woodland cover from 14% to 20% by 2030 to offset the greenhouse gas emissions from agriculture.

Contested institutions? Traditional leaders and land access and control in communal areas of Eastern Cape Province, South Africa

The South African government has endeavoured to strengthen property rights in communal areas and develop civil society institutions for community-led development and natural resource management. However, the effectiveness of this remains unclear as the emergence and operation of civil society institutions in these areas is potentially constrained by the persistence of traditional authorities. Focusing on the former Transkei region of Eastern Cape Province, three case study communities are used examine the extent to which local institutions overlap in issues of land access and control.

Crop and water productivity, profitability and energy consumption pattern of a maize-based crop sequence in the North Eastern Himalayan Region, India

Inde

Mono-cropping is the most common farming practice followed in the North Eastern Hilly Region (NEHR) of India and farmers leave the land fallow after harvesting the main crop. The identification of suitable sequential crops is essential to increase the cropping intensity, land-use efficiency and overall productivity of the land. Therefore, a study was carried out during 2008–09, 2009–10 and 2010–11 on maize (rainy season) followed by table pea, mustard, French bean and groundnut (post rainy season). Sequence crops were imposed with paddy straw mulch at 5.0 t ha⁻¹ and without mulch.

Responses to climate change and farming policies by rural communities in northern China: A report on field observation and farmers’ perception in dryland north Shaanxi and Ningxia

Chine

To address land degradation and rural poverty the Chinese government has put in place a series of land conversion programmes in the Loess Plateau area in northern China. In addition to problems arising from unsustainable land use, water resource availability driven in part by climatic forcing is also a threat to livelihoods in this region. To understand climate impacts on farming practice in poor areas of China, field observation and village reconnaissance took place in the summer of 2009 in three selected counties of Shaanxi and Ningxia Province, northern China.

LandCaRe DSS – An interactive decision support system for climate change impact assessment and the analysis of potential agricultural land use adaptation strategies

Journal Articles & Books
Décembre, 2013

Decision support to develop viable climate change adaptation strategies for agriculture and regional land use management encompasses a wide range of options and issues. Up to now, only a few suitable tools and methods have existed for farmers and regional stakeholders that support the process of decision-making in this field. The interactive model-based spatial information and decision support system LandCaRe DSS attempts to close the existing methodical gap.
