"This paper presents an empirical case study about farmer management of rice genetic resources in two communities of Nepal, drawing on interdisciplinary, participatory research that involved farmers, rice geneticists, and social scientists. The decision-making process of farm households is modeled and estimated in order to provide information for the design of community-based conservation programs.

This study aims to explore and quantify systematic similarities and differences between four major global cropping systems products: the dataset of monthly irrigated and rainfed crop areas around the year 2000 (MIRCA2000), the spatial production allocation model (SPAM), the global agroecological zone (GAEZ) dataset, and the M3 dataset developed by Monfreda, Ramankutty, and Foley.

This study assesses whether the recent public and private efforts to improve farmers’ access to mechanical power in Ghana have had the intended effects on the country’s agricultural sector. Using panel survey data, this paper analyses the drivers of farm mechanization and its net impacts on cropland expansion and farming system intensification in northern Ghana. Several factors explain the use and use intensity of agricultural mechanization, including landholding size, total labor and fertilizer use per hectare, chemical use, and amount of land left fallow.

Land degradation in the tropics is strongly associated with human population growth. The latter phenomenon is quite marked in humid areas and in the temperate highlands (Jahnke 1982). Notably in the plateaux of Sub-Saharan Africa and Asia, several pastoral systems have gradually evolved into mixed farming, in order to cope with such pressure (Ruthenberg, 1980). Land is more intensively utilized as population density increases since mixed systems are more efficient than specialized crop or livestock systems (McIntire et al.,1992). In fact, livestock crop integration allows:

The Vision of the present cross-sectoral Forestry Strategy 2020 (FS2020) establishes that by 2020, the Government of the Lao PDR envisages a sizeable, vigorous and robust forestry sector continuing in its role as one of the leading sectors advancing national socio-economic development. A sector in which scientifically-managed natural production forests generate timber and non-timber products at sustainable levels with village participation, under supervision and technical support from well-staffed, well-trained local and national government units.

These provisions lay down amendments and addenda to the Nitrates Action Programme Regulations. New definitions are inserted in regulation 2 (livestock unit, deep litter system). The addenda concern exemptions for units of bovines, swine, ovines, caprines and rabbits, as well as production units of layer hens and broilers managed by a single farmer having an animal population equivalent or lower than the animal populations listed in Schedule IV (but in any case less than three livestock units).

The overall aim of the present Forest and Wildlife Policy is the conservation and sustainable development of forest and wildlife resources for the maintenance of environmental stability and continuous flow of optimum benefits from the socio-cultural and economic goods and services that the forest environment provides to the present and future generations whilst fulfilling Ghana’s commitments under international agreements and conventions.
