This paper investigates how land size
measurements vary across three common land measurement
methods (farmer estimated, Global Positioning System (GPS),
and compass and rope), and the effect of land size
measurement error on the inverse farm size relationship and
input demand functions. The analysis utilizes plot-level
data from the second wave of the Nigeria General Household
Survey Panel, as well as a supplementary land validation

Agricultural water management projects
that take an inclusive, participatory gendersensitive
approach at all levels of the project
cycle help increase project effectiveness and
improve account of livelihood concerns of
women and the rural poor. Participatory
planning methods; creation of genderspecific
indicators; continuous monitoring;
and beneficiary-led impact assessment are
key features of this approach.

China is considered one of the most seriously eroded countries in the world. The
many causes of this degradation can be divided into natural, human-induced and root causes.
The consequences of watershed degradation are severe and reach even beyond the country’s
boundaries. Addressing this issue requires a sustainable participatory and integrated watershed
management approach. The Loess Plateau Watershed Rehabilitation Projects, implemented by
the Ministry of Water Resources and co-financed by the World Bank has provided a model that

Este trabajo tiene por objetivo el análisis de la calidad del agua del arroyo Langueyú para determinar el estado de situación y su relación con la gestión de los recursos hídricos superficiales a nivel local. Se tuvieron en cuenta antecedentes hidrológicos regionales. Se efectuaron recorridos siguiendo el cauce del arroyo desde la cuenca alta, al Sur de la ciudad de Tandil incluyendo sus tributarios Blanco y Del Fuerte, hasta la intersección con la Ruta Provincial Nº 30. Se seleccionaron 9 sitios en los que se realizaron muestreos de calidad de agua en el período 2009-2011.

Water scarcity is one of the greatest challenges of the twenty-first century. Agriculture is both a cause and a casualty of water scarcity. It accounts for an estimated 70 percent of global water withdrawals, with freshwater resources heavily stressed by irrigation and food production. While demand for water for agriculture and other uses are increasing rapidly, climate change also affects fresh water resources negatively both in terms of quantity and quality.

NAEZ Project Proposal's goal is to improve monitoring and analysis of agricultural production system by strengthening land resources information management systems and Agro-Ecological Zones (AEZ) to support agricultural policies and climate-change adaptation in Afghanistan.

The relevance of the sustainable use, management and conservation of aquatic genetic resources (AqGR) for food and agriculture is relatively well known and documented, but there is still an urgent need to preserve and better manage existing aquatic diversity to enhance its contribution to food security, nutrition and livelihoods. Aquatic genetic resources for food and agriculture include thousands of species, which are found in the world’s oceans, seas, lakes, reservoirs, rivers, rice paddies and other wetlands, and also in aquaculture facilities in marine, brackish and fresh waters.
