Food Security: The Challenge of Feeding 9 Billion People
Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are a further threat. But the world can produce more food and can ensure that it is used more efficiently and equitably.
Implications of Climate Change for Fresh Groundwater Resources in Coastal Aquifers in Bangladesh
The objective of this study is to improve understanding of the implications of climate change for the groundwater systems in coastal Bangladesh. This is achieved by: (a) obtaining available geologic, hydrologic, and geochemical information on coastal aquifers of Bangladesh; (b) developing groundwater flow and salt transport models representing general features and conditions along the coast of Bangladesh; and (c) simulating potential changes in the groundwater systems due to various aspects of human activity and climate change.
Assessment of Innovative Approaches for Flood Risk Management and Financing in Agriculture
Floods are a major source of risk for the agricultural sector. Flood risk in the agricultural sector primarily arises from river flooding, flash floods, and coastal flooding. The impacts of floods can result in sizable agricultural damages at the local level. Floods in agricultural zones expose agricultural producers, agricultural supply chains, rural financial institutions (such as agricultural banks), and governments to financial risks due to the loss of crops, delinquency on seasonal production loans, damage to infrastructure and loss of public revenues.
Mongolia
The primary objective of the Southern Gobi Regional Environmental Assessment (REA) is to provide guidance for sustainable management of environmental resources in the future development of the Southern Gobi Region (SGR), development that will be led by rapid expansion of mining.

El mundo se ve distinto desde Charagua. Recibí al año 2010 en esta localidad del Chaco Boliviano, que acaba de ganar por referéndum su reconocimiento como municipio indígena, aunque realmente es intercultural, debido a una presencia importante de población guaraní, criolla, mestiza, menonita, quechua y aymara. Gran parte de sus habitantes se dedica a actividades agropecuarias como principal fuente de ingresos.
Fighting for land security in Southern Africa
It has emerged quite clearly from Urban LandMark’s work in South Africa – and increasingly in the region – that the emergence of more sophisticated property markets has taken place locally and in most larger cities in the region. While there might be a need to assist these markets to develop further, in particular the need to build market institutions and professions, these groupings tend to increase their own capacities as the markets develop, mostly with little assistance.
Climate change and natural resources conflicts in Africa
Africa is among the most likely vulnerable regions of the world that are to be negatively impacted by climate change. The continent’s vulnerability to climate change arises from a combination of many factors, including extreme poverty, high rate of population increase, frequent natural disasters such as droughts and floods, and agricultural systems that are heavily dependent on rainfall. Under-development in some African states has also been a function of existing protracted natural resource conflicts and climate change worsens the situation.

Potential Impacts of Climate Change on Land Use in the Lao PDR
Objectives of the study were to assess the evidence of climate change and the additional likely changes in the climate up to 2050. Further the recent changes in land use and their major drivers have been addessed. The outcome of the study are recommendation for adapted farming practices, taking predicted changes in climate into account.
An econometric investigation of impacts of sustainable land management practices on soil carbon and yield risk
We investigate the impacts of sustainable land management practices on soil carbon stocks and also impacts of soil carbon on the mean and variance of crop production using econometric tools. Using a cross-sectional plot-level dataset collected from three agroecological zones of Uganda with soil carbon measured at a depth of 0 to 15 centimeters, our results have robustly shown that irrigation, fertilizers, improved fallow, crop residues, mulching, and trash lines are positively and significantly associated with higher soil carbon, corroborating results from agronomic experiments.
The role of collective action and property rights in climage change strategies
The well-documented threats posed by climate change are serious and potentially devastating to the global community. The geographic areas that are most susceptible to the effects of climate change, such as increased droughts and flooding, are also the regions where the majority of the world’s poor live.
