Three analytical systems often used in farm systems analyses are discussed in this chapter: (1) linear programming, (2) dynamic programming, and (3) systems simulation.

This chapter provides a brief overview of forest hydrology modelling approaches for answering important global research and management questions. Many hundreds of hydrological models have been applied globally across multiple decades to represent and predict forest hydrological processes. The focus ...

This chapter initially provides a review of computer structure and operational systems, but more importantly provides coverage of farm computer uses that might be helpful to a farmer. This latter aspect is about the software available. Areas where application software is available are outlined,...

Currently, agriculture is the biggest consumer of water globally. About 60% of global consumptive water demand is from the agriculture sector. With the world population increasing to about 9 billion, and the per capita GDP rising, the demand for domestic and industrial water will increase in future ...

Climate change is now a reality and is expected to have profound impacts on agricultural production systems, thus threatening food security. Local observational evidence of changing climate based on available historical weather data-sets is presented for selected locations in the Philippines. In...

Future inflow to the irrigation scheme of the Syr Darya Basin is modelled under two climate scenarios, based on outputs of International Panel on Climate Change (IPCC) core models run under IPCC-SRES A2 emission scenario. Under the GFDL99-R30-based scenario, the mean annual flow (MAF) is likely to...

This chapter will present the impacts of farm-level adaptation strategies on farm household income and food security under the changing climate in Northern region of Ghana using a bio-economic modelling approach. The modeling approach captures the heterogeneity of important resources of farm...

Models that describe the dynamics of soil organic carbon (SOC) can be useful tools when estimating the impacts of land cover, land management and climate change on ecosystems. The development of SOC models started with single-compartment models that assumed a constant decomposition rate. As...

This book is a compendium of studies on climate change challenges and adaptations at the farm level, capturing research carried out across the continents of Asia and Africa. Chapter 1 is on the introduction to climate change vulnerability and adaptation strategies with rural farm-level perspective. ...

Crop level adaptations to present and future climate are indispensable to farmers because their livelihood depends on crop-based income. Hence, quantifying impact and adaptation options at the field level is yet another important step in adaptation planning at farm-level. This chapter analyses the...
