This paper provides a quantitative assessment of the likely economy-wide impacts of agricultural productivity improvements in Sri Lanka. A static multi sector Computable General Equilibrium (CGE) model of the Sri Lankan economy using the input-output table for year 2000 is employed highlighting the agricultural sector and its interactions with other production sectors in the economy. The result...

1. Agriculture is the predominant user (75-80%) of the available freshwater resource in many parts of the world. At present most of the water used to grow crops is derived from rainfed soil moisture, with non-irrigated agriculture accounting for some 60% of production in developing countries. Although irrigation provides only 10% of agricultural water use and covers just around 20% of the cropl...

Rainfall is important for food production plan, water resource management and all activity, plans in the nature. The occurrence of prolonged dry period or heavy rain at the critical stages of the crop growth and development may lead to significant reduce crop yield. Indian is an agricultural country and its economy is largely based upon crop productivity. Thus rainfall prediction becomes a sign...

Terrain, an important limiting factor in land use change, strongly influences agricultural productivity. This study investigated the topographical characteristics of agricultural potential productivity of cropland transformations in China during the first decade of the 21st century, and explored the impacts of cropland transformations with different terrains on agricultural potential productivi...

The main objective of CRP 1.1 Dryland Systems is to achieve sustainable agricultural development in the drylands. On the technical level, it will aim at reducing demand for water per unit crop area, improving water capture and storage, increasing productivity per unit of water at farm and landscape levels, and changing land-use practices to better manage risk and sustainably enhance production ...

The world population is projected to become a staggering 8.3 billion by 2030 from about 6 billion today, which will aggravate food insecurity especially in developing countries [31]. By 2050, developing countries will account for 93% of cereal and 85% of meat demand growth [73]. In agricultural crop production systems, insects, diseases and weeds continue to threaten sustainability and account ...

The study examined the nexus of interest rate deregulation, lending rate and agricultural productivity in Nigeria by employing co-integration and error correction techniques on annual data spanning 1986 to 2009. Nigeria has embarked on several agricultural policy measures aimed at repositioning and enhancing variables that affects the sector’s productivity. The findings from the study showed th...

We assess long-run patterns of global agricultural productivity growth between 1970 and 2005 and examine the relationship between investments in technology capital and productivity. To measure agricultural total factor productivity (TFP) we employ a Solow-type growth accounting method to decompose output growth into input and TFP growth. For technology capital we construct two indexes reflectin...
