Simple and widely adopted sustainable soil management (SSM) practices, especially improvements in the management and quality of farmyard manure (FYM), have enabled many thousands of small-scale farmers in the Middle Hills of Nepal to increase organic matter in their soils. This has been achieved without increases in livestock numbers or in the quantity of manure available. The organic matter contents have increased in all of five time series of on-farm topsoil monitoring over periods of one to three years, at rates varying from 2% to 27%.

This research analyzes the adoption patterns among cotton farmers for remote sensing, yield monitors, soil testing, soil electrical conductivity, and other precision agriculture technologies using a Multiple Indicator Multiple Causation regression model. Adoption patterns are analyzed using principle component analysis to determine natural technology groupings. Identified bundles are regressed on farm structure and operator characteristics.

Acacia mearnsii De Wild (black wattle) is an important plantation species for tannin production and woodchip exports in South Africa and Brazil. This study provides an updated overview of the black wattle industries in both countries, including planted areas and land ownership, silviculture and management, bark extract production, woodchip exports, as well as key research and development issues. The current total planted area to black wattle is 110 000 ha in South Africa and c. 170 000 ha in Brazil. In both countries black wattle is mainly cultivated by farmers (c.

Land degradation in terms of soil degradation is a major environmental issue posing threat to sustainable livelihood in the semi-arid region of Central Myanmar. However, the studies on soil degradation status and its impacts in this region are very scanty. The objective of this study was to determine the impact of land degradation on crop production both in terms of area and yield in the Dry Zone of Myanmar. Remote sensing and geographic information system-based modelling was utilized to assess and map soil erosion rates.

The common use of pesticide is a major challenge in trying to accomplish sustainable agriculture. Farming systems based on integrated pest management (IPM) technologies can reduce the use of pesticides to a great extent without causing harm to the yield. Therefore, Bangladesh, like many developing countries, launched IPM technologies to reduce the adverse effects of pesticides in social, economic and environmental aspects. This study made an attempt to analyze the level of IPM adoption and the intensity of IPM practices by vegetable farmers of Narsingdi district, Bangladesh.

In the Mekong Delta, alluvial clay soils have been used intensively over many generations for rice monoculture. Currently, farmers are confronted by problems of declining land productivity. Rotations comprising rice and upland crops can increase soil quality, but appropriate cropping systems for paddy soils have received relatively little attention. We therefore established a multiyear field experiment to evaluate the long‐term effects of cropping systems with different rotations on soil chemical quality.

The global rush for land has provoked diverse policy responses from host countries. While some governments are facilitating ‘land grabs’ within their borders, others have restricted land acquisitions by foreigners. Drawing from the Brazilian case, I argue that such restrictive regulations may be limited in their effectiveness because they apply a state‐centric geopolitical logic to a threat that is largely de‐territorialized and financialized.

In recent decades, markets have become widely used for environmental resources. Prime examples include water rights where trade enables water to be allocated to the most profitable crops, and allows farmers more flexibility to cope with climatic variability (Bjornlund 2003). Similarly, tradable rights for air pollution minimize the cost of meeting air quality targets (Stavins 1998). The same principles can potentially be widely applied to biodiversity conservation. In this issue, we are fortunate to have a short but diverse series of papers on tradable rights in conservation.

This report focuses on areas with highest potential efficiency gains to increase the value for money from investments in core public goods and services such as extension, irrigation and rural roads. This is a first attempt to carry out such an analysis in Cambodia, and even in the Greater Mekong sub-region. Based on extensive data gathering and surveys, this chapter analyzes the efficiency and effectiveness of agricultural sector expenditures in Cambodia and assesses various options for increasing the impact of government expenditures on agricultural growth.

The performance of the Malian economy is largely dependent on the performance of the agricultural sector. The overall good growth in the Malian economy over the last several years is attributed to the agricultural GDP growth. Since 1995, the economy grew at about 5 percent per year until 2010, but a global recession, the military coup and terrorist activity caused a noticeable slowdown in GDP to about 1.2 percent in 2011-2012. The economic growth has resumed at a slow pace since 2013 and is currently estimated around 4.5 percent for 2014-2015.

In sub-Saharan Africa women comprise a large proportion of the agricultural labor force, yet they are consistently found to be less productive than male farmers. The gender gap in agricultural productivity-measured by the value of agricultural produce per unit of cultivated land-ranges from 4-25 percent, depending on the country and the crop.1 The World Bank Africa Gender Innovation Lab, UN Women, and the UNDP-UNEP Poverty-Environment Initiative jointly produced a report to quantify the cost of the gender gap and the potential gains from closing that gap in Malawi, Tanzania, and Uganda.
